1 .TH Server "Empire4 Changes"
2 .NA Empire4 "Changes from the Empire3 server to the Empire4 Server"
5 There have been several changes/fixes made to the Empire3 code in the
6 new Empire4 Server. This outlines the various changes and how they
7 will affect you, the player. These were coded as the Wolfpack project,
8 and bug-reports should be sent to <wolfpack@wolfpackempire.com>.
10 Changes to Empire 4.3.33 - Fri Mar 13 06:03:30 UTC 2015
11 * New client option -r for restricted mode. Contributed by Marisa
13 * The add syntax deprecated in 4.3.29 is now gone.
14 * The explore, move, test, transport syntax deprecated in 4.3.27 is
16 * The bmap flag syntax deprecated in 4.3.27 is now gone.
17 * Stricter configuration validation:
18 - Reject odd WORLD_X instead of making it even silently.
20 - Reject missiles that lack capability VTOL instead of adding VTOL
22 - Reject ships that can carry planes, but have neither capability
23 plane nor miss, instead of adding miss silently.
24 * Outlaw ships that can drop depth charges, but not fire. No such
25 ships exist in the stock game. 4.3.31 permitted them, but keeping
26 them working has turned out to be bothersome.
27 * Changes to fire and torpedo:
28 - Don't disclose that the torpedo's path to the target is blocked
29 by land when the target is out of range. Screwed up in 4.2.2.
30 - When a submarine gets hit by return fire after firing its deck
31 gun, the defender again learns the submarine's uid and type, just
32 like for surface ships. This is how it worked before Empire 2.3.
33 - When a submarine gets hit by return fire after launching a
34 torpedo, the defender again learns the submarine's uid. Before
35 Empire 2.3, he learned uid and type.
36 - Print "Kaboom" even when the target is out of range.
37 - Always clear missions when firing guns or dropping depth charges.
38 Screwed up when missions were added in Chainsaw.
39 - Report "Sector X,Y ready to fire" instead of "Sector X,Y firing",
40 because the sector isn't firing, yet, then. Also report ships
41 and land units ready to fire.
42 - Suppress bulletin when player shells or torpedoes his own ship.
43 * When artillery on a bridge span shelled down the supporting bridge
44 head, the bridge fell and the artillery drowned alright. But then
45 the bridge rose right back. Broken in 4.3.14.
46 * Fix board to charge mobility even when defender is less than 100%
47 efficient. Broken in Empire 2.
48 * The convert command charged security land units mobility until
49 4.3.16 broke that. Drop this undocumented feature instead of
51 * Report the owner of ships sunk by return torpedoes instead of POGO.
52 Screwed up when return torpedoes were added in Chainsaw.
53 * Don't disclose uid, type and owner of torpedoed submarines. The
54 latter leaked through the news.
56 - Fix damage to mobility when bombing planes. Has always been
58 - Include position when reporting bombing of a land unit, like we
60 - Suppress bulletin when player bombs his own assets.
61 - Report bombing of plane to owner once, not twice.
62 - Don't permit bombing of dead planes. Missed when we did the same
63 for dead ships and land units in 4.3.16.
64 * Changes to retreat and lretreat:
65 - Be less loquacious when changing orders.
66 - Deprecate pseudo-condition 'c'. Use retreat path 'h' to cancel
68 - Change query syntax from "retreat SHIPS" to "retreat SHIPS q".
69 Consistent with mission, and makes prompting for arguments more
70 usable. Keep accepting the old syntax for now, but deprecate it.
71 - Reject invalid retreat paths instead of silently ignoring invalid
72 characters during retreat. Unfortunately, the path needs to be
73 valid even with deprecated pseudo-condition 'c', where it's not
74 actually used. This might break some existing usage.
75 - Fail without charging BTUs when the player gives no conditions.
76 - Fix infinite loop when third argument contains '?'. Broken in
78 * Rename retreat flag "torped" to "torpedoed" in xdump retreat-flags.
79 This could conceivably break clients. No actual breakage is known.
80 * Rewrite automatic retreat to fix its many bugs and inconsistencies
81 with navigate and march:
82 - When a ship defeats a boarding party, but suffers enough damage
83 to sink, retreat the victim's group (if any) instead of ship#0.
84 - Permit retreat exactly when navigate and march would be
85 permitted. Before, land units happily retreated while on the
86 trading block (forbidden with march since 4.0.9), crewless
87 (likewise since 4.0.0), kidnapped in a foreign sector
88 (inconsistent since land units were added in Chainsaw 3), loaded
89 on a ship (likewise) or a land unit (inconsistent since that
90 became possible in 4.0.0). Ships retreated while on the trading
91 block (forbidden with navigate since 4.0.9).
92 - Land units can now retreat into foreign sectors exactly when they
93 could march there: when the sector is allied, or when the land
94 unit is a spy (with the usual risks).
95 - Land units can now retreat into mountains.
96 - Land unit retreat now resets fortification.
97 - Group retreat now happens only along a single path. Before, you
98 could scatter a group in several directions, and even retreat in
99 far away places. The latter was a highly abusable design flaw.
100 - Bulletins provide more useful information in fewer words. In
101 particular, they always report the end sector.
102 - Fix retreat after a torpedo hit to include the torpedo damage in
103 its mobility cost calculation.
104 - When retreat runs into a sector that cannot be entered, don't
105 consume the retreat direction.
106 - Don't charge mobility for retreating in direction 'h'
107 - You can no longer make your own ships or land units retreat.
108 - Clear mission only when the ship or land unit actually retreats.
109 - Land unit group retreat could corrupt the land unit file or crash
110 the server. Screwed up when Chainsaw added land unit retreat.
111 - Fix ship retreat when helpless. Surface ships claimed to retreat
112 in a bulletin, but that was a lie. Submarines didn't even
114 * Don't tell the player he sunk a ship when it survives an attack
115 with bomb, fire, launch or torpedo, but sinks during retreat. bomb
116 even reported where it had retreated to when it sank.
117 * Land mine fixes, affecting march and, if option INTERDICT_ATT is
118 enabled, attack and assault:
119 - Fix march sub-command 'm' to not let non-engineers hit mines.
120 Broken in Empire 2. Fixed in 4.0.17 for ships only.
121 - Engineers now risk hitting mines twice instead of once on sector
122 entry, just like minesweepers.
123 - No sweeping with zero mobility. Screwed up when Chainsaw added
125 * Navigate and march cleanup and bug hunt:
126 - Stop on non-fatal mine hits, too. Before, we carried on, and
127 ships that lost all crew were left behind only at the next
128 prompt. Note that we already stop on non-fatal interdiction
129 damage since Empire 2.
130 - Fix use-after-free when a flagship or leader stays behind without
131 a prompt following immediately.
132 - When something other than movement charged mobility, the charge
133 was lost on the next movement, unless there was a prompt in
134 between. For instance, mobility lost to mine hits could come
136 - Fix parser not to get confused by white-space.
137 - Make ships use radar always, not just most of the time.
138 - Land units now use radar automatically like ships.
139 - Report flagship and leader changes immediately, and always.
140 Before, they were reported only around a prompt.
141 - Wipe mission and retreat orders less eagerly. Before, they where
142 sometimes wiped even for ships and land units the command
144 - Give up fortification only when a land unit actually moves or
146 - Report where exactly ships and land units sweep mines.
147 - Nicer error messages for sub-command 'm'.
148 - Fix sub-command 'm' not to drop engineers without mobility from
150 - When denying ships entry to an unfriendly sector with canals,
151 don't disclose whether it's above 2%.
152 - Both navigate and march now require all their ships and land
153 units to be in the same sector. Support for scattered ships and
154 land units complicates the code and blows up the test matrix.
155 It's also rather obscure; I suspect accidental use has been more
156 frequent than intentional use.
157 - Check for sector abandonment before anyone marches instead of
158 right before moving the last land unit. Fixes a bug that could
159 scatter the group when something interferes while waiting for the
160 player to confirm abandonment.
161 - When marching a mixed group of spies and non-spies into a
162 non-allied sector, remove non-spies from the group, and move the
163 spies. Before, only the spies before the first non-spy moved
164 into the non-allied sector, which could scatter the group.
165 Screwed up when 4.0.0 added spy units.
166 - Don't permit trains to march out of sectors without rail.
167 - When navigating a mixed group of ships with and without canal
168 capability into a canal, remove incapable ships from the group,
169 and move the capable ships. Before, only the ships before the
170 first incapable ship moved into the canal, which could scatter
171 the group. Broken in 4.3.0.
172 - Fix navigate buffer overrun for impossibly long paths taken. No
173 remotely sane game configuration provides a ship fast enough to
174 trigger it. Broken in 4.0.0.
175 * Remove option SAIL (commands follow, mquota, sail, unsail; ship
176 selectors mquota, path, follow) and autonav (commands order,
177 qorder, sorder; ship selectors xstart, xend, ystart, yend,
178 cargostart, cargoend, amtstart, amtend, autonav) due to multiple
180 - The orders are executed at the update. Crafty players can use
181 them to get around the update window.
182 - Usability is poor, especially for autonav.
183 - Few players use them.
184 - Documentation is inaccurate.
185 - Code has bugs, some of them critical.
186 - It's almost 1300 lines of rather crufty code nobody wants to
188 - Code sharing complicates maintenance of the navigate command.
189 * Configuration tables reader and empdump improvements:
190 - Better error messages.
191 - Export now omits redundant data by default. Use empdump -c to
193 - Import can cope with omitted sectors and realms. Omitted sectors
194 become sea, and omitted realms become empty.
195 - Column order is now unrestricted. Before, some tables required
196 an ID field to come first.
197 - Support splitting any table. Before, tables sect, news, lost,
198 realm, game, infrastructure could not be split.
199 - Support strings longer than 65535 characters.
200 * Fix empdump -i to reject strings that are one character too long.
201 The bug affected ship table columns path, name and rpath, land
202 table column rpath, nat table columns cname, passwd, ip, hostname
204 * Reject nat selectors relations, contacts and rejects, because they
205 don't actually make sense. They exist just for xdump.
206 * Drop the code to resolve player IP address. It's been disabled
207 since 4.2.13. Deprecate nat selector hostname.
208 * Fix bridge spans next to a bridge tower or head taking damage to
209 fall when they should with EASY_BRIDGES off. Has always been
211 * Fix bridge spans next to a collapsing bridge tower to fall when
212 they should with EASY_BRIDGES on. Broken in 4.3.12.
213 * When you scrap a plane, you get crew back only proportionally to
216 - Fail the attempt to build a bridge not next to land or bridge
218 - Deities can now build anywhere, without materials, work or money.
219 - Building a plane no longer uses at least one military. Military
220 for crew are now rounded just like the other materials. The
221 special case dates back to 4.2.3.
222 - Report missing materials more nicely.
223 - You now need the required materials rounded up to be present.
224 Actual use is still randomly rounded. Before, crafty players
225 could exploit the rounding to save materials, or build
226 sufficiently cheap things without materials. In the stock game,
227 linf and many plane types could be built without materials.
228 * Remove option TREATIES. Usability is very poor, virtually nobody
229 uses them, conditions are incomplete, the code is buggy, and a
231 * Test suite improvements:
232 - Coverage extended to commands build, navigate, march, fire,
233 torpedo, retreat, lretreat, falling bridges, automatic retreat,
234 command info page completeness, and the empdump utility program.
235 - Maintainability of tests much improved.
236 - Test harness refactoring.
238 * Adjust stack sizes. Stack overflow was possibly for tiny worlds.
239 * Fix start, stop to not operate on dead units when used by a deity.
240 Screwed up when start, stop were extended to units in 4.3.6.
241 * Nukes can be grouped into stockpiles, just like ships can be
242 grouped into fleets. The new command stockpile does for nukes what
243 fleet does for ships. Likewise the new nuke selector stockpile.
244 * wingadd no longer costs BTUs, for consistency with fleetadd and
247 - Keep missions centered on ship, plane or land unit centered when
248 teleporting it. Screwed up when Chainsaw added missions.
249 - Preserve "does not follow" when copying ships. Preserve "no
250 distribution center" when copying sectors, and don't mess up
251 coastal flag. Screwed when Chainsaw added the means to copy a
253 - You can now edit nukes.
254 - Suppress bulletin on no-op ship, plane, land unit location
255 change. Screwed up in 4.3.32.
256 - You can now edit ship, plane and land unit types.
257 - Changing the owner of a ship, plane or land unit away from POGO
259 * Fix "make uninstall" to remove HTML info pages (which are not
260 installed by default) and directory share/empire/.
261 * Fix "make install" to remove stale formatted info pages.
262 * Code refactoring and cleanup.
263 * Info file fixes and improvements.
265 Changes to Empire 4.3.32 - Sun Aug 25 07:55:34 UTC 2013
266 * Fix an LWP stack overflow observed on AIX 7.1.
267 * Fix portability bug in standalone client Makefile
268 * Fix portability bug in configure test for curses.
269 * The break command now honors new designation of sanctuaries.
270 * Changes to edit, give, setsector, setresource, swapsector:
271 - Generalize edit to multiple objects: accept
272 <SECTS|SHIPS|PLANES|LANDS|NATS> argument instead of just
273 <SECT|SHIP|PLANE|LAND|NAT>. Obsoletes setsector and setresource.
274 - Make interactive "edit c" detect and handle concurrent updates,
276 - Don't reprint edited object when done with it.
277 - Always print a message describing the actual change. Necessary
278 to give the deity a chance to catch unexpected changes, e.g. a
279 player moving away stuff right before a give command, leaving
280 fewer items than the deity intends to take. Existing messages
281 improved, missing ones added.
282 - Consistently send bulletins to the victim / beneficiary of deity
283 meddling, except when changing stuff mortals can't see.
284 - Report much more deity meddling in the news (subject to option
286 - More robust argument checking. Before, careless deity edits
287 could cause internal errors. Much bounds checking was missing,
288 inconsistent or wrong.
289 - Teleport planes and land units to carrier on load.
290 - Refuse to move planes and land units on carriers.
291 - Fix stack smash in edit l key 'L' that can mess up sector file.
292 - Fix setsector to again print actual landmine change for occupied
293 sectors. Broken in 4.3.31.
294 - Suppress bulletins for acts of god to himself.
295 - Suppress news for acts of god to gods.
296 - Suppress news and bulletins on no-op acts of god.
297 - Always send bulletins from POGO. Name the meddling deity in the
298 bulletin text instead. Inconsistent since Chainsaw.
299 - Make interactive edit accept empty key argument again.
300 - Make interactive edit treat blank input like empty input.
301 - Don't let edit put a land unit or plane on two carriers
302 - Do not disclose when a deity destroys a ship, tell the ex-owner
303 only that he lost it.
304 - edit p and u now show the edited unit like edit s.
305 - edit s now shows the edited ship even when its owner is invalid.
306 * Clean up output of satellite, land, sorder and mission for world
307 sizes between 200 and 1998. cutoff and level still have issues
309 * Plug harmless file descriptor leak on OpenBSD with IPv6. Broken in
311 * New doc/contributing explains how to contribute to Empire.
312 * Code refactoring and cleanup.
313 * Info page, manual page and documentation fixes and clarifications.
315 Changes to Empire 4.3.31 - Sun May 12 16:58:34 UTC 2013
316 * Fix read beyond end of conditional argument on missing operand.
317 * Don't put broken links into info pages formatted as HTML.
318 * Permit ships that can drop depth charges, but not fire. No such
319 ships exist in the stock game.
320 * Consistently require guns for dropping depth charges. Before, only
321 the fire command required guns (since 4.3.12 and before 4.0.6).
322 * Change econfig key rollover_avail_max from 0 to 50.
323 * Make sector production more predictable. Commands production and
324 budget are now a bit more accurate.
325 * Fix bugs that messed up xdump lost and xdump trade on big endian
326 hosts (broken in 4.3.8), and made the server fail during startup on
327 most big endian hosts (broken in 4.3.12).
328 * Build process robustness fixes.
329 * Use "Level: Obsolete" to mark obsolete info pages, and drop "info
331 * Server now uses IPv4 format for IPv4-mapped addresses. Simplifies
332 safe use of econfig key privip.
333 * Server logs a few more network connection details.
334 * Fixes and workarounds for econfig key listen_addr "" (which is the
335 default) when the system has both IPv4 and IPv6 addresses
337 - Server accepted only IPv6 connections on Windows and BSDs. Fix
338 to accept IPv4 ones, too.
339 - Except for OpenBSD, where the fix doesn't work. Accept IPv4
340 connections instead of IPv6 ones there, and document how to get
341 IPv6 accepted instead.
342 - Linux systems are frequently configured in a way that makes the
343 server accept only IPv4 connections. Document workaround: use
345 * Change fairland island size probability distribution: roll two dice
346 instead of one. This makes extreme sizes much less likely.
347 * Make fairland record the island number in the deity territory.
348 * Fix extension of market bidding time when high bidder changes.
349 Introduced broken in 4.0.7, with insufficient fixes in 4.0.9 and
351 * Fix market not to mess up ridiculously high unit prices. Has been
352 broken since 4.0.0 introduced the market.
353 * Fix melting of big piles of stuff by ridiculously heavy fallout.
354 Has been broken since fallout exists.
355 * Fix crash on edit s, p, u key 'U' with negative argument.
356 * When a deity builds ships or land units in foreign sectors, they're
357 given to the sector owner. This lets POGO build them, and it's how
358 build works for planes and nukes.
359 * Fix PRNG (pseudo-random number generator) seeding to resist
360 guessing: seed with a kernel random number. If we can't get one,
361 fall back to a hash of high-resolution time and process ID. This
362 should happen only on old systems or Windows. Far worse than a
363 kernel random number, but far better than just low-resolution time.
364 Fairland's seeding used to be low-resolution time and process ID,
365 but regressed in 4.2.20 to just time.
366 * Switch PRNG from BSD random() to Mersenne Twister. This is a is a
367 proven, high-quality PRNG.
368 * Fix tiny error in distribution of some die rolls.
369 * Increase land unit retreat chance and nuclear damage's chance to
370 destroy a nuke by one percentage point, for simplicity.
371 * Merge news items a bit more aggressively.
372 * Fix a year 2038 bug in news item merging.
373 * Retire the nightly build.
374 * New make target check. Just a few tests for now, derived from the
375 smoke test that used to be part of the nightly build.
376 * Really fix accepting connections from "long" IPv6 address. The fix
377 in 4.3.23 could mess up player's host address in player output and
378 logs, and cause extra "Last connection" messages.
379 * Take ship cost into account when picking missile interdiction
380 target. Broken in 4.3.8.
381 * Really fix give, setsector and setresource not to wipe out
382 concurrent updates. The fix in 4.3.27 was insufficient.
383 * Fix setsector not to disclose number of landmines to occupier.
384 * Make capital fail more nicely when the sector is unsuitable. Its
385 argument must now be a single sector. Before, it silently picked
386 the first suitable one when the argument selected several. Has
387 always been that way, and never documented.
388 * Changes to option GODNEWS:
389 - Deity command give could downgrade the deity's relations to the
390 sector owner when GODNEWS was enabled. No more.
391 - Likewise, deity commands edit and setsector can no longer
392 downgrade the victim's relations to the deity.
393 - News enabled by GODNEWS no longer affect news headlines.
394 * Fix bomb, drop, fly, paradrop, recon and sweep to again accept a
395 destination sector equal to the assembly point. Broken in 4.3.27.
396 * Fix portability bug in configure test for Windows API.
397 * More user friendly server startup: journal open errors are detected
398 while the server still runs in the foreground, which makes it
399 possible to complain to stderr and to exit unsuccessfully.
401 - Forbid selling conquered populace. Only relevant when the deity
402 allows selling civilians, which is probably a bad idea.
403 - Permit selling military by default.
404 - Forbid selling ships and land units carrying unsalable cargo.
405 * Scrapping ships and land units now spreads the plague
406 * Don't let scrap give away civilians, kill them off instead.
407 * Pilots and air cargo now spread the plague.
408 * Don't let fly and drop give away civilians.
409 * Fix fly to permit flying civs to a carrier in an occupied sector.
411 * Don't let planes fly to a carrier without sufficient space.
412 Before, planes that didn't fit were teleported home, which could be
413 abused. Broken in 4.3.17. Almost the same bug was previously
415 * Fix tend to foreign ships:
416 - Refuse to tend civilians to foreign ships.
417 - Don't leak friendly foreign ships' commodity cargo.
418 - Continue with remaining target ships after skipping a foreign one
419 when tending a negative amount of commodities.
420 All broken when Chainsaw 2 added tending to allies.
421 * march sub-command 'm' can now sweep own landmines.
422 * Land units no longer sweep allied landmines, except when executing
423 march sub-command 'm'. They don't hit them since 4.3.27. Sweeping
425 * Fix bmap commands not to parse empty flags argument as "revert".
427 * Code refactoring and cleanup.
428 * Info page fixes and clarifications.
430 Changes to Empire 4.3.30 - Tue May 22 18:34:52 UTC 2012
431 * Disable damage to base sector or ship when missile explodes on
432 launch for now, because damage done to other missiles there can be
433 wiped out in some cases. Broken in Empire 2.
434 * Fix navigate and march not to wipe out concurrent updates.
435 Abusable, but probably not worthwhile.
436 * Fix some buffer overruns in fairland. Has always been broken.
437 * Fix arm to require nuke and plane to be in the same sector. A
438 remote nuke got teleported to its plane when the plane moved.
440 * Change login command kill (used by client option -k) to kill less
441 ruthlessly: send a flash message and try to flush output, exactly
442 like a server shutdown does.
443 * Fix server shutdown to wait for player threads to reach a safe
444 state. Before, player threads raced with shutdown, and failed to
445 update the treasury, record play time, and write log entries when
446 they lost. Bug goes back to Empire 2. Patched partially or
447 unsuccessfully in 4.2.10, 4.2.12, 4.2.20, 4.3.6, 4.3.10 and 4.3.23.
448 The race was hard to lose in practice, until an unrelated
449 "simplification" in 4.3.23 could get player threads stuck sending
450 output after shutdown aborted a command.
451 * Idle timeout changes:
452 - The grace period for clients to complete login and logout is now
453 separate from the idle timeout. Configurable with new econfig
454 key login_grace_time, default is 120 seconds.
455 - The idle timeout for visitors is now separate from the one for
456 players. Configurable with new econfig key max_idle_visitor,
457 default is five minutes.
458 - Fix the idle timeout when the connection gets stuck sending
459 output. Broken in 4.3.20.
460 - Idle timeout during execute now terminates the connection, not
461 just the execute command.
462 * Fix stack smash in build. Remote hole! Broken when Empire 2 added
463 the confirmation prompt.
464 * Fix stack smash in scrap and scuttle. Remote hole! Broken when
465 Chainsaw added the confirmation prompt. Additionally, the
466 confirmation prompt is misleading when the player supplies
467 conditionals. Redesign the flawed prompt.
468 * Fix execute's echo of the command. Broken in 4.3.28.
469 * The mobility cost of retreating a defending land unit was
470 calculated for an uninitialized sector. This could charge
471 incorrect mobility, prevent retreat, or, if the stars align just
472 right, crash the server. Broken in 4.3.6.
473 * Commands cutoff, headlines, land, lstat, motd, neweff, payoff,
474 qorder, sorder, and wall now behave like the other information
475 query commands when the player's connection can't take more output:
476 they pause to let other code run.
477 * Revised command permissions:
478 - arm and disarm no longer require money, for consistency with the
479 other commands to move stuff around.
480 - satellite no longer requires money, for consistency with lookout,
481 radar, sonar and skywatch.
482 - qorder, sorder, survey and test no longer require a capital, for
483 consistency with the other commands that report on stuff the
485 - start and stop no longer require a capital, for consistency with
486 the other commands to control production.
487 - fortify now requires a capital, for consistency with mission,
489 - Anybody may now use country, echo and financial.
490 - Visitors can no longer use census, commodity, map, nmap,
491 sinfrastructure (useless without sectors), read (visitors don't
492 get any telegrams), and change (always failed).
493 - Players can no longer use map and nmap before break. This is
494 consistent with all the other commands to examine the
495 environment. It also prevents people from trying multiple
496 unbroken countries in a blitz to find the one with the nicest
498 - Players can now use resource before break, just like census.
499 * read could swallow the first telegram header when showing the
500 telegrams that arrived while waiting for the player to confirm
501 deletion. Broken in 4.3.29.
502 * Fix 'm' in path argument of explore, move, transport:
503 - Don't moan about deprecated argument syntax ('m' without a space
504 before its argument) even when there's no argument.
505 - Recognize the flags argument again.
508 - Command market is no longer available to visitors, because it
509 triggers execution of trades that have become ready.
510 - Fix a race condition that could cause commodity trades to be
511 executed multiple times. Abusing this to duplicate commodities
512 seems tricky, but possible. Broken in Empire 3.
513 - Don't expropriate sellers of units. POGO got the the money, the
514 telegrams and made the news, the seller got nothing. Broken in
516 * Login command quit and server shutdown could lose player output.
517 4.3.23 tried to fix the shutdown case, but the fix was incomplete.
518 * Fix login command quit to really quit. It sometimes just swallowed
519 buffered input, at least on some systems.
520 * 4.2.22's fairer command scheduling failed to cover the execute
522 * When a client shuts down input transmission to log out, output
523 could get lost. Our client never does that.
524 * Don't skip post command treasury update and status notification on
525 EOF from player, after quit command, and when command is aborted by
526 server shutdown. An unluckily timed EOF or shutdown can deprive a
527 player of money gained from scuttling tradeships or sacking a
528 capital. Can be abused to build bridges and infrastructure free of
529 charge. Can also be abused to designate sectors for free, but the
530 stock game's sector types are all free anyway. Has always been
532 * Fix client not to send an empty line on player interrupt (normally
533 ^C) before the first command. This was missed in 4.3.26.
534 * Code and info page cleanup.
535 * Documentation fixes.
537 Changes to Empire 4.3.29 - Fri Jan 20 19:20:20 UTC 2012
538 * drop and fly from carrier could fail to load last civilian or
540 * Telegram and announcement changes:
541 - wire no longer loops to show announcements that arrived while
542 waiting for the player to confirm deletion.
543 - At most five seconds worth of messages are now squashed together
544 into one. Before, only the time between adjacent telegrams was
545 limited, not the total time.
546 - When telegrams arrived while read was waiting for the player to
547 confirm deletion, and we then showed them, we nevertheless
548 claimed "you have new telegrams" before the next command prompt.
549 Only with toggle inform off. Known bug since Empire 2.
550 - Fix read not to clobber asynchronous notification of telegrams
551 arriving while waiting for the player to confirm deletion.
552 - Fix wire not to reset number of pending telegrams with toggle
553 inform on. Broken when Empire 2 introduced toggle inform.
554 - The number of pending announcements was off when announcements
555 were squashed together.
556 - More careful error handling and logging.
557 * Ensure all of an update's output goes into a single production
559 - Avoid splitting it up when the update is slow. Empire 2 already
560 did that for the number of pending telegrams, but not for read.
561 - Don't turn parts of it into BULLETINs. Autonav and sail could do
563 * files now creates POGO with user interface flags beep, coastwatch,
564 sonar and techlists set, for consistency with add.
565 * Change newcap back to not wiping the country (it wiped since
566 4.3.12). Additionally, leave levels and telegrams alone.
567 * Changes to deity command add:
568 - Require confirmation for unadvisable actions.
569 - Refuse to touch a country while it's being played.
570 - Don't crash on negative country number.
571 - Create deities with money, just like files creates POGO.
572 - Always reset the country completely, not just when adding a
574 - Rename argument "new" to "player". Keep recognizing "new" for
575 now, but deprecate it.
576 - Drop argument "active". If you really want to create a player
577 country without a capital, add the player country normally, then
578 activate it with edit instead of newcap.
579 - Drop the obscure sector check and wipe option. If you really
580 need to wipe out a country, there's much more to wipe than just
582 - Drop the undocumented land unit destruction feature.
583 * Permit no-op country name change again. Accidentally outlawed in
585 * Plug a few minor memory and file descriptor leaks.
586 * Fix use-after-free when plane gets shot down or aborted in
587 dogfight. Broken in 4.3.27.
589 * Info page and manual page fixes.
591 Changes to Empire 4.3.28 - Sat Jul 16 11:30:53 UTC 2011
592 * Don't let POGO (#0) navigate dead ships, and march dead land units.
593 The ghosts even got sighted and interdicted, and could hit mines.
594 Has always been that way.
595 * llook can't see land units and planes loaded on land units anymore.
596 * Fix board to ignore land units loaded on land units when testing
597 whether a sector can board. Broken in 4.0.17.
598 * Fix transport to reject planes loaded on land units. The plane
599 remained on its carrier. When the land unit moved, the plane was
600 teleported right back to it. Broken since Chainsaw 3 added land
602 * Fix lradar not to let land units loaded on land units use radar.
603 Broken since 4.0.0 added trains.
604 * Fix strength to ignore land units loaded on land units. Broken in
606 * Fix navigate and march to find paths longer than a few sectors
607 again (7 for 64 bit hosts, 3 for 32 bit hosts). Broken in 4.3.27.
608 * march sub-command 'i' now shows number of military and land units
610 * New server option -F to force start even when state looks bad.
611 Risks crashes and further corruption, but gives deities a chance to
612 fix up a bad game state with edit commands and such.
613 * empdump -x no longer refuses to export game state that looks bad.
614 Gives deities another tool to fix up a bad game state.
615 * Land units loaded on land units fight che again, as they used to
617 * When a land unit dies fighting che, land units loaded on it get
618 unloaded, and planes loaded on it die. Before, the update left
619 them stuck on their dead carrier. Impact like the next item.
620 Abusable. Broken since Chainsaw 3 added land units.
621 * The update no longer destroys ships, planes and land units for lack
622 of maintenance. Before, it left any embarked planes, land units
623 and nukes on their dead carrier. In this state, units behaved as
624 if their carrier was still alive, with additional protection from
625 the fact that a dead carrier can't be damaged or boarded. If
626 another unit with the same number got built, it picked up the stuck
627 cargo. The cargo got teleported to its new carrier when the
628 carrier moved. Abusable, but it involves going broke, so it's
629 rarely practical. Slightly more practical before 4.3.6 removed
630 budget priorities. Broken for ships and land units when Empire 2
631 added their maintenance cost, and for planes when 4.3.3 replaced
632 nuclear stockpiles by nuke units.
633 * Fix bogus internal error triggered by navigate and march
634 sub-commands 'r', 'l' and 's'. Broken in 4.3.27.
635 * Fix client not to reject redirections and execute containing
636 non-ASCII characters with a bogus scary warning when using UTF-8.
637 * Fix execute not to mangle non-ASCII characters in the argument when
638 prompting for it while login option utf-8 is on.
639 * Fix handling of non-ASCII and control characters in batch files.
640 * Conversion from UTF-8 to ASCII ate the character following a
641 replaced non-ASCII character. Buffer overrun possible if the
642 terminating zero gets eaten. Could happen in players, read, flash,
644 * Fix handling of empty commands:
645 - Time used was not updated.
646 - Mortal player wasn't logged off for game hours, game down, and
648 - Notifications were delayed: going broke, becoming solvent, new
649 telegrams (toggle inform off only), new announcements, capital
651 * Minor tweaks to nightly build.
652 * Server's and empdump's sanity checking of configuration and game
653 state is now more rigorous.
654 * Deity xdump no longer dumps unused countries' realms.
655 * Remove option LANDSPIES. Deities can customize the land table to
657 * Remove option TRADESHIPS. Deities can customize the ship table to
659 * Configuration table changes (builtin and custom):
660 - Rows must be in ascending uid order.
661 - Omitting rows in tables item, sect-chr and infrastructure is no
663 - Custom tables now replace the builtin table completely. Before,
664 omitted rows defaulted to the builtin version, except at the end
665 of a table. Commenting out unwanted stuff just works now.
666 - Permit custom table product having fewer than 14 entries.
667 - Reject custom tables where customization has no effect (updates,
668 table, meta, all symbol tables) or where it's unsafe (news-chr).
669 - Input is checked more rigorously.
671 - Don't touch plane file when import fails.
672 - Refuse import of incorrectly sized table instead of silently
673 creating one the server will reject.
674 - Replace old state completely. Before, omitted rows in the dump
675 defaulted to the old state, except at the end of a table.
676 - Input is checked more rigorously.
677 * Fix xdump updates not to dump bogus extra updates.
678 * Fix use-after-free when a plane got shot down or aborted by flak.
680 * Friendlier diagnostics in the build command.
681 * Fix build to set nuke's tech exactly like for ships, planes and
682 land units. It's not currently used for anything.
683 * Research required for nukes was slightly off sometimes due to
685 * Bridge building required 0.005 tech less than advertised, fix.
686 * "show nuke" now obeys toggle techlists.
687 * Fix "show land s" to show columns xpl and lnd again. Broken in
689 * Code refactoring and cleanup.
690 * Documentation on custom tables and xdump updated.
693 Changes to Empire 4.3.27 - Sun Apr 17 11:36:29 UTC 2011
694 * License upgrade to GPL version 3 or later.
695 * Fix buy not to wipe out concurrent updates. Can be abused to
696 duplicate commodities.
697 * Don't let fighters, SAMs and ABMs intercept while on trading block.
698 * Don't let missiles interdict ships or land units while on trading
700 * Fix client to log long input lines untruncated.
701 * Fix client crash for long input lines.
702 * info subject pages now mark unusually long pages with a !.
703 * The edit command keys deprecated in 4.3.15, 4.3.17 and 4.3.20 are
705 * Fix give, setsector and setres not to wipe out concurrent updates.
706 * Fix explore, move, test, transport not to ignore spaces in path
707 arguments. Broken in 4.3.7. Deprecate use of 'm' without space
709 * Improvements to map drawing commands:
710 - Don't fail silently when asked to draw a map around an invalid
711 unit, explain the problem.
712 - Deprecate bmap flag "r". Use (a prefix of) "revert" instead.
713 - bmap flags following "t" are no longer ignored. However, info
714 pages previously documented an argument "true" in addition to
715 flag "t". To keep that working, keep ignoring flags following
716 "t" when they're bad. But deprecate that usage.
717 - Reverting the bmap no longer draws a map.
718 - Bad conditionals could make the commands misinterpret their first
720 - The commands now fail when they reject their second argument.
721 * The xdump syntax deprecated in 4.3.12 is now gone.
722 * Fix satellite to fail on bad conditionals instead of ignoring them.
723 * Journal improvements:
724 - Optional logging of output.
725 - Long lines are no longer truncated.
726 - Login phase input is now logged, too.
727 - Commands are now logged. Allows making sense of input without
729 * Option BRIDGETOWERS is now disabled by default.
730 * Bridge towers now take 300 hcms to build, down from 400.
731 * Fix stop orders to expire even when the country is broke. Broken
733 * Fix march and navigate not to advise on "legal directions" when
736 - Much faster, especially for distribution, i.e. where it matters
737 most. Speedups in excess of 30x have been observed for updates
738 taken from real games.
739 - Old land path finder leaked memory occasionally.
740 - Old land path finder overran buffers for very long paths. A
741 malicious player can arrange sufficiently long paths, but it
742 takes a lot of land. Distribution, the distribute command, land
743 unit reaction, and automatic supply now handle arbitrary long
744 paths. Commands explore, move, test, transport, march, navigate
745 and path now handle paths up to 1023 characters. Command
746 bestpath shows paths longer than 1023 characters with the tail
748 - Old sea and air path finder treated destinations as unreachable
749 when the best path was longer than 99 characters. Command sorder
750 now handles arbitrary long paths. Commands bomb, drop, fly,
751 paradrop, recon, sweep and sail now handle paths up to 1023
752 characters. Autonav considers up to 1023 characters at the
753 update. Planes can fly missions up to 1023 sectors from their
755 * Automatic supply charged mobility for the path back to the source
756 instead forward to the sink.
757 * Make bestpath work for deities in foreign land.
758 * More robust savecore example script.
759 * Fix buffer overruns in the lookout, spy, map and nmap commands when
760 WORLD_X * WORLD_Y is not a multiple of 16.
761 * The path command's maps weren't always fitted to the path
762 correctly. Broken in 4.3.17.
763 * Land units no longer hit allied mines.
764 * Change sharebmap with yourself to do nothing instead of telling you
765 you're not friendly to yourself.
766 * You can now flash yourself. Enjoy!
767 * A race condition could make the flash command claim an ally was not
768 logged on when he was. Hard to trigger outside the lab.
769 * The flash command no longer prints "Flash sent" for deities. It's
770 annoying. It never did that for mortals.
771 * Plug memory leaks in mission code on a number of conditions:
772 - Submarines moving where own planes would interdict hostile
774 - Ground combat where countries hostile to one of the parties would
775 support if relations were right (allied to one party, at war with
777 - Ships or land units moving within hostile missile mission op
779 - Any player action within marine missile mission op areas that
780 could trigger the missile owners' missions.
782 - When you ordered a sector to attack with military, but lost the
783 sector before the attack was executed, and the new owner was
784 allied to you, the server got confused: it let the military
785 attack even though they were already dead, but not occupy.
786 - When you ordered a land unit to attack from an allied sector, and
787 the sector got lost before the attack was executed, the server
788 reported things as if you had owned the sector yourself. The
789 land unit still attacked when the new owner was also allied to
791 - When a land unit attacked out of an allied sector, its mobility
792 cost was computed as if the ally owned the land unit. Attacking
793 sectors old-owned by that ally was too cheap, and taking back
794 one's own was too expensive.
795 * Fix trade ships to pay off in own harbor. Broken in 4.3.17.
796 * Remove option SLOW_WAR. It hasn't been enabled in a public game
797 for years, and the code implementing it was buggy.
798 * Fix a bug in sail that limited the sail path to 27 instead of the
799 intended 28 characters.
800 * Fix race condition in transmission of flash and telegram
801 information messages that could double output and possibly crash
803 * Planes get to sweep and sonar only after flak and interception.
804 * Don't limit the radar command's range to fit its output into a
805 world map without clipping. The limiting goes back to Chainsaw 2.
806 * Make flak vs. pinpoint bombing consistent with ordinary flak:
807 - 4.3.6 reduced the plane abort chance on damage, but missed the
808 additional flak vs. pinpoint bombing. Fix that.
809 - Fix to charge mobility appropriate for damage.
810 * Prettier flak damage reporting.
811 * Fix bugs that could cause bmap updates from recon and satellite to
813 * Fix lookout to properly report sector ownership to deities.
814 * Suppress bogus messages deities with non-zero country number got
815 when attempting to navigate foreign ships or march foreign land
816 units. Such deity use hasn't worked since Empire 2.
817 * Deities can no longer fly foreign planes. It didn't fully work
818 since Chainsaw 3, and can trigger internal errors since 4.3.11.
819 * Don't split lines over several bulletins. The read command
820 normally merges these bulletins, but if they are more than five
821 seconds apart (clock jumped somehow), we get a bulletin header in
822 the middle of a line. Broken since Empire 2.
823 * Don't beep when plane, land unit or nuke die on a collapsing
824 bridge. Not nice, because it could beep many times, and could put
825 beeps in bulletins. Beeping was added in 4.0.18.
826 * Minor improvements to nuclear damage reporting.
827 * When a deity dropped a foreign nuke, parts of the output went to
828 the owner of the nuke instead of the deity.
829 * When a player triggered a foreign missile launch (mission or
830 interception), and the missile exploded on launch, part of the
831 report went to the player instead of the missile owner. This
832 disclosed the missile owner's origin. Broken in Empire 2.
833 * When autonav reported to a ship owner that it can't load or unload
834 foreign civilians, it used the sector owner's coordinate system.
835 This disclosed the sector owner's origin. Abusable.
836 * When nuclear damage bounced off a sanctuary, the bulletin to the
837 sanctuary owner used the attacker's coordinate system. This
838 disclosed the attacker's origin.
839 * When a deity used sweep, lmine, sail or sabotage with a foreign
840 plane, land unit or ship, its location was reported in the foreign
842 * When a deity asked for a foreign nation report, the capital
843 location was reported in the foreign coordinate system.
844 * Code refactoring and cleanup.
845 * Info file improvements.
847 Changes to Empire 4.3.26 - Mon May 24 16:37:40 UTC 2010
848 * Land units loaded on ships or land units can no longer fight che.
849 * When foreign land units were present, a che revolt could damage
850 them instead of the defending land units. This could let defenders
851 survive the revolt. They were captured or blown up if che took
853 * Fix che revolt to damage only land units that actually fight
854 * Fix loading x-light missiles on ships without capability plane.
855 These ships could only use their x-light slots for x-light planes,
856 not their plane slots. Broken in 4.3.17.
857 * Update bmap when nuclear detonation makes wasteland.
858 * Fix fly and drop to report discarded cargo items correctly.
859 * New client option -s to specify server host and port.
860 * Hitting landmines could crash the server. When not, the damage
861 reduction for capability engineer was applied unpredictably.
863 * Fix retreat and lretreat condition 'c'. Broken in 4.3.16.
864 * coastwatch and skywatch could see too far. Up to one sector for
865 practical radar ranges.
866 * skywatch now reports satellite uids. The uid is required for
867 launching a-sats since 4.3.23.
868 * Fix client not to send an empty line of input before aborting the
869 command on player interrupt (normally ^C).
870 * Fix sabotage not to kill the spy every time. Broken in 4.3.17.
872 * Info page fixes, manual page improvements.
874 Changes to Empire 4.3.25 - Sun Mar 21 08:27:37 UTC 2010
875 * Hitting seamines could crash the server. When not, the damage
876 reduction for capability sweep was applied unpredictably. Broken
878 * When an interdiction did damage other than collateral damage, the
879 planes that intercepted it from interdicted carriers used no
880 petrol. 4.3.24 fixed only the "no damage" case.
881 * Ship anti-missile defense failed to charge shells when the ship was
882 interdicted. The fix in 4.3.24 covered only launch.
883 * Fix a bug in navigate and march that let players lay mines free of
884 charge. Also fix them not to prompt for the number of mines.
885 * Missile exploding on launch could not damage its base if it was
886 armed with a nuke. Broken in 4.3.23.
887 * When a torpedo attack triggered a return torpedo, the news reported
888 it to be fired by the attacker instead of the defender.
889 * Interdiction attacked submarines with surface-only weapons. Broken
891 * Fix a bug in lradar, path, radar, route, satellite, sect and survey
892 that could leak maps to other players. Broken in 4.2.0. Fixed in
893 4.2.8 for bmap, lbmap, lmap, map, nmap, pbmap, pmap, sbmap and smap
895 * files could clobber the game when reading confirmation fails.
896 * fairland no longer rejects small worlds without trying.
898 Changes to Empire 4.3.24 - Tue Jan 26 21:29:14 UTC 2010
899 * The client sometimes hung under Windows when the server closed the
900 connection. Broken in 4.3.23.
901 * Fix navigate and march not to crash the server when a path argument
902 consists of a valid path plus whitespace. Broken in 4.3.7.
903 * When a client sent a blank line in the login phase, the server
904 crashed on some systems.
905 * Fix crash bug in bomb, drop, fly, paradrop, recon and sail. Broken
907 * Fix bogus internal error on escort, recon, and satellite launch.
908 Mostly harmless, as error recovery worked fine. Broken in 4.3.23.
909 * Stop ship and land unit movement on interdiction even when it does
911 * When an interdiction did no or only collateral damage, the planes
912 that intercepted it from interdicted carriers used no petrol, and
913 interdicted land units were immune to collateral damage.
914 * The limit for the number of sectors, ships, planes, land units,
915 nukes, and so forth is now large enough not to matter. It used to
916 be 32768 on common machines. The sector limit was introduced in
917 4.3.12. World x- and y-size are still limited to 65536 on common
919 * News use much less space, and thus I/O. Space was wasted in
920 4.3.12. Side effects of the change:
921 - Expiry of old news no longer updates news timestamps. Updating
922 timestamps was wrong, because it defeated incremental xdump news.
923 - The empdump utility can no longer update timestamps of imported
924 news. Unfortunate, as it breaks incremental xdump news.
925 * New news selector duration, the time span covered by this news item
927 * ABMs failed to charge supplies when their sector was the
928 intercepted missile's target. The stock game's ABMs use no
930 * Ship anti-missile defense failed to charge shells when the ship was
931 the missile's target.
932 * Code refactoring and cleanup.
934 Changes to Empire 4.3.23 - Sun Dec 13 16:34:49 UTC 2009
935 * Fix missile interception not to intercept tactical and marine
936 missiles attacking missiles or satellites. No such missiles exist
937 in the stock game. Interception of tactical ABMs could crash the
938 server. Broken in Empire 2.
939 * Missiles missing their target do collateral damage again. Was
940 disabled because of bugs in 4.0.18 for manual launch and in 4.3.16
941 for automatic launch.
942 * News reported victim as actor for sub-launched anti-sat and ABM.
943 * Defense value of missiles vs. ABMs and satellites vs. anti-sats
944 failed to improve with tech.
945 * Fix a bug that let missiles interdict ships outside their op area.
946 This could happen when a group navigating together was partly
948 * Only bomb strategic and launch at sector can use nukes. Before,
949 they could also be used by missions, bomb pinpoint, and launch at
950 ships, but there were several bugs and inconsistencies, and the
951 code was messy. The arm command now rejects marine missiles in
952 addition to satellites, ABMs and SAMs, and clears the mission. The
953 mission command now rejects planes armed with nukes.
954 * Missiles exploding on launch pad no longer set off their nukes.
955 * The launch command now more accurately reports why a missile can't
956 be equipped. It no longer draws supplies automatically.
957 * Manually launched anti-sat now always kills when it hits, for
958 consistency with automatically launched ones.
959 * Don't permit nukes on satellites, ABMs and SAMs. Nukes on
960 satellites could be armed and disarmed even in orbit. Nukes on
961 ABMs and SAMs were lost without effect when their missile
962 intercepted. The stock game is not affected, because its
963 satellites, ABMs and SAMs all have zero load.
964 * Remove obsolete plane capabilities stealth and half-stealth. Not
965 used by the stock game.
966 * Penalize fighter combat value for any load, not just bombs. The
967 stock game's fighters can't carry anything but bombs.
968 * Make bomb work for non-tactical cargo bomber. No such planes exist
970 * Revised cargo plane rules: a cargo flight can be either an airlift
971 or an airdrop now. Airlifts carry more cargo than airdrops. A
972 cargo drop or paradrop with a non-VTOL plane is an airdrop.
973 Anything else is an airlift. This makes paradrop loads consistent
974 with drop loads. Paradrop with VTOL transports now carries twice
975 the punch, and drop with non-VTOL transports hauls less than fly.
976 In particular, the stock game's tr can't drop guns anymore.
977 * Enforce plane selection rules more tightly:
978 - bomb command can select only planes with capability bomber or
979 tactical. Before, other planes with non-zero load flew along,
980 but their bombs were silently lost.
981 - sweep command can select only planes with capability sweep.
982 Before, other planes performed ordinary reconnaissance instead.
983 - drop command can select only planes with capability cargo.
984 Before, other planes flew along but dropped nothing.
985 * Fix paradrop to fail without destroying the paratroopers when the
986 player owns the target sector.
987 * Launching an anti-sat now takes the target plane as argument.
988 Before, it took a sector argument, and targeted the lowest-numbered
989 satellite there. Rather inconvenient when your own satellite masks
991 * Remove option PINPOINTMISSILE. Deities can customize the plane
992 table to disable marine missiles.
993 * Ridiculously impotent nukes could do unpredictable interdiction
994 damage. No such nukes exist in the stock game.
995 * The production command could mispredict resource-depleting level
996 production. No such products exist in the stock game. In fact,
997 they'd be highly unusual.
998 * The update could crash or corrupt the game when a (misconfigured)
999 product depleted resource "none".
1000 * Revamp the Windows port based on ideas stolen from Gnulib. Share
1001 the code between server and client.
1002 * Don't log out player when update aborts a command under Windows.
1003 Broken in 4.3.20, and not fully fixed in 4.3.21.
1004 * Fix accepting connections from hosts with "long" IPv6 address. The
1005 internal buffer had insufficient space.
1006 * Delay shutdown up to 3s to let player output buffers drain.
1007 * Fix a race between main thread and player threads, which could
1008 theoretically make the server crash on start.
1009 * Clean up synchronization between commands, update and shutdown, and
1010 when player threads sleep on I/O.
1011 * Clean up the cruft that has accumulated in and behind the empio
1012 interface, and, to a lesser degree, the empthread interface.
1013 * Fix time difference underflows in pthread and Windows code. They
1014 could potentially cause hangs, although none have been observed.
1015 * Make budget's "Sector building" line look better.
1016 * Make sector maintenance cost configurable. New sect-chr selector
1017 maint. Capitals now pay maintenance regardless of efficiency.
1018 * Overhaul show sect b.
1019 * Fix mine production resource limit for sector peffic != 100. This
1020 affects mountains in the stock game, but only with an impractically
1021 large number of ETUs per update.
1022 * Code refactoring and cleanup.
1023 * Info file fixes and improvements.
1025 Changes to Empire 4.3.22 - Sat Apr 25 11:56:29 UTC 2009
1026 * Fix a Windows client bug that could lead to hangs, at least with
1027 some versions of the C run-time. Broken in 4.3.11.
1028 * Allow building without curses terminfo. Highlighting in the client
1030 * Really fix bomb not to wipe out plane updates made while it asked
1031 for pinpoint targets. The fix in 4.3.21 didn't cover escorts.
1032 * Fix tend land not to wipe out concurrent updates.
1033 * Automatic supply fixes:
1034 - Ships with just two shells could fire a torpedo to return fire or
1036 - Ships with just one shell could use their anti-missile defense.
1037 - Land units were considered in supply even when they had not quite
1038 enough supplies. Such land units could defend without penalty,
1041 * Fix update to take dead units off carriers.
1042 * Standalone client distribution built empire instead of empire.exe
1043 for Windows. Broken in 4.3.0.
1044 * Fix client to abort script execution on SIGINT.
1045 * Fix Windows client not to hang on EOF on standard input when that
1047 * Fix a client bug that could make it hang when EOF on standard input
1048 follows an execute command closely.
1049 * Seamines under bridge spans were disabled a long time ago, in
1050 Empire 2. The drop command refuses to mine there. Change mine
1051 command to do so as well.
1052 * Seamines under bridge spans were mistaken for landmines by ground
1053 combat, land units retreating from bombs, and non-land unit ground
1055 * When a bridge tower collapsed, its landmines magically became
1057 * Don't log out player when he interrupts a command. Broken in
1059 * Code cleanup and portability improvements.
1060 * Info file and documentation fixes.
1062 Changes to Empire 4.3.21 - Mon Mar 9 21:34:52 UTC 2009
1063 * Fix swapsector not to wipe out concurrent changes to the swapped
1065 * Fix a bug in crash dumping that could mess up the journal and, at
1066 least in theory, mess up commands info, read, turn, and wire;
1067 announcement expiry, and reading of econfig and schedule.
1068 * Fix bomb not to wipe out plane updates made while it asked for
1070 * When bombing ships with a force containing both planes with and
1071 without capability ASW, the bomb command could fail to report
1072 presence of submarines, and could refuse to bomb ships when there
1073 were only submarines.
1074 * Leaving land units behind after a victorious attack could in some
1075 cases wipe out changes made to them since the victory.
1076 * The timestamp selectors added to commodity, load and trade in
1077 4.3.12 could lead to spurious command failures. None have been
1078 observed in the wild.
1079 * Don't log out player when update aborts a command. Broken in
1081 * Code refactoring and cleanup.
1083 Changes to Empire 4.3.20 - Fri Feb 20 18:14:20 UTC 2009
1084 * Option LOANS is now disabled by default.
1085 * Option RAILWAYS is now enabled by default.
1086 * Many fixes to automatic supply:
1087 - Planes flying interception or support missions, abms intercepting
1088 ballistic missiles, and the launch command for missiles and
1089 anti-sats could all supply more shells than necessary, lose
1090 shells, or conjure them up.
1091 - Ships shooting down marine missiles could supply more shells than
1092 necessary, or lose shells.
1093 - Supply ships could conjure up shells when firing guns using
1094 multiple shells, or launching torpedoes, or dropping depth
1095 charges, or shooting down marine missiles. No supply ships
1096 capable of doing that exist in the stock game.
1097 - Supply engineers could conjure up shells when laying mines. They
1098 don't exist in the stock game.
1099 - load, lload and supply could supply land units with enough food
1100 from the sector containing them to starve the sector.
1101 - Sectors were charged too much mobility for moving supplies
1103 - Land units serving as supply source no longer draw supplies
1104 recursively, because the bugs there are too hard to fix to be
1106 - Defending and reacting units only checked whether they could draw
1107 supplies, but didn't actually draw them.
1108 - load, lload, supply, assault and board no longer supply land
1109 units from ships carrying them. This feature, added in 4.0.14,
1110 was inconsistent with other ways to supply.
1111 - Don't use automatic supply to avoid starvation at the update. It
1112 adds complexity to the update. How much good it does to players
1113 is highly doubtful; certainly nobody can rely on it. It isn't
1114 covered by the starvation command. Ships or land units could
1115 steal enough food from their sector to make it starve.
1116 - lmine could only fetch shells for engineers that use ammo. The
1117 stock game's engineers all do.
1118 The changes listed for load and lload are actually lies, because
1119 supply has been disabled there since 4.3.17.
1120 * Don't let an engineer lay mines while it is on a ship or land unit,
1121 or in a foreign sector.
1122 * Sectors and ships no longer need shells to fire flak.
1123 * Use IPv4 and v6 only when suitable interfaces are configured.
1124 * Fix turn off not to fail when the message is empty. Broken in
1126 * Don't nag the deity about game hours restriction in force all the
1128 * Tell deity when the game is down, just like players. Also make the
1129 information available in xdump, as game selector down.
1130 * Corrupt mailboxes could crash the server.
1131 * Fix reject accept. Broken in 4.3.4.
1132 * If a player was at a prompt when the deity turned the game down, he
1133 was allowed to enter one more command.
1134 * Air defense is no longer separate from interception. Putting a
1135 plane on air defense now merely changes where it intercepts.
1136 Separate air defense added too much pointless complexity. Its
1137 implementation violated design assumptions of the intercept code.
1138 Because of that, the same plane could intercept both an air defense
1139 mission and the planes that triggered it, and the damage it
1140 received in the first interception was wiped out.
1141 * Intercept the same all along the flight path. In each sector, any
1142 country owning the sector, a surface ship or a land unit there gets
1143 to intercept. Before, only the sector owner got to intercept,
1144 except for the assembly point and the target sector. In the target
1145 sector, any country owning surface ships or land units got to
1146 intercept in addition to the sector owner. Thus, a sector owner
1147 with surface ships or land units there got to intercept twice. The
1148 sector owner did not get to intercept at the assembly point,
1149 even when it was the target sector.
1150 * Spotting rule changes:
1151 - Ships and land units now spot overflying planes along all of the
1152 flight path instead of just the target sector, and no longer
1153 report allied planes.
1154 - Planes now spot ships and land units only when flying recon or
1155 sweep, and along all of their flight path instead of just the
1156 target sector. It still takes a spy plane to identify ships and
1158 - Planes now spot ships and land units in a sector even when all
1160 - Planes now spot all foreign ships and land units, not just
1162 * Fix SAM interception for intercepts other than the first.
1163 * Fix air defense and flak over sectors allied to the planes. Air
1164 defense was broken in Empire 2. Flak was broken in 4.2.8.
1165 * Establishing contact by spotting planes from sectors didn't work.
1166 * Fix reconnaissance patrols to use sonar when any capable plane is
1167 present. Before, all planes had to be capable.
1168 * Fix recon and sweep not to spy after all spy planes are gone.
1169 * Fix a bug that made multiple clients running on the same Windows
1170 machine interfere with each other. Broken in 4.3.11.
1171 * Fix enforcing game hours for players already logged in. Broken in
1173 * Fix distribution not to abandon a distribution center by exporting
1175 * Many fixes to load, unload, lload and lunload:
1176 - Now usable for deities.
1177 - Plug loopholes that let you steal foreign commodities by making
1178 load/lload unload and unload/lunload load through use of negative
1180 - Fix not to let you give away civilians.
1181 - You can't use lload in foreign sectors or lunload with foreign
1182 land units anymore. Loading stuff in foreign sectors was
1183 prohibited already for ships.
1184 - lload and lunload now work on foreign land units only when
1185 they're explicitly named by uid. This matches behavior of load
1187 - Fix to test relations of foreign object's owner to player instead
1188 of the other way round.
1189 * Make sure land units with maximum mobility can attack mountains.
1190 * Fix land unit attack mobility cost. Broken in 4.3.6.
1191 * Conditions comparing string-valued selectors like wing to unquoted
1192 values are now interpreted more smartly. Before, unquoted strings
1193 were prone to be interpreted as selector names even when that made
1194 no sense. You still have to disambiguate truly ambiguous cases
1195 like w=w for planes, e.g. as wing=w or w='w'.
1196 * Fix reporting of shot spies in news. Broken in 4.3.16.
1197 * Remove econfig key mission_mob_cost. Questionable feature, and
1198 hasn't been used in a long time.
1199 * Reserve and escort missions now have an op-area, like all the other
1201 * Land units now react only when on a reserve mission. The lrange
1202 command is gone. The edit command still accepts and ignores the
1203 land unit key 'P' for compatibility, but it is deprecated.
1204 * Fix a bug that could mess up mission op-area when the range of
1205 ship, plane or land unit on the mission decreases, e.g. through the
1207 * Reserve missions no longer give a bonus to reaction range.
1209 * Code refactoring and cleanup.
1211 Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
1212 * LWP doesn't work with Darwin due to OS bugs, avoid it for now.
1213 * Don't let ships double-retreat first on 'i' (injured) and then on
1214 'h' (helpless) when shelled.
1215 * Fix a bug that suppressed the "sunk!" message. Broken in 4.3.17.
1216 * Log out player when maximum time per day is exceeded. Before, he
1217 could remain logged in with visitor privileges only, but once
1218 logged out could not log back in.
1219 * If a player was at a prompt when either game hours restriction
1220 started or maximum time per day was exceeded, he was allowed to
1221 enter one more command.
1222 * Deitying a capital failed to charge money and report news. Broken
1224 * Overhaul accounting of play time, fixing minor inaccuracies.
1225 * Fix parsing of 24:00 in econfig key game_hours and
1227 * New option RAILWAYS.
1228 * Che ages just like military reserves (1% per 24 ETUs).
1229 * Permit ships to assault the sector they're in.
1230 * Sectors eating less than one unit of food don't make one unit of
1231 food for free anymore. They still can't starve.
1232 * New concept sector terrain. Deities can use it to make sectors
1233 other than wilderness redesignatable. See sect.config for more
1235 * Represent play time in seconds rather than minutes. This affects
1236 xdump: nat selector minused (counting minutes) is replaced by
1237 timeused (counting seconds).
1238 * Improved nightly build, with additional tests.
1240 Changes to Empire 4.3.18 - Sat Oct 18 18:39:17 UTC 2008
1241 * Fix building of planes, land units and nukes with uids that have
1242 never been used before. This could crash the server on some
1243 systems in certain states. Broken in 4.3.17.
1244 * Improved nightly build, with restructured and extended tests.
1246 Changes to Empire 4.3.17 - Sat Sep 20 16:07:44 UTC 2008
1247 * Fix standalone client build for Windows. Broken in 4.3.11.
1248 * Disable automatic supply of land units on load for now, it's
1249 broken, and can be abused to duplicate supplies.
1250 * Make trade show exactly what's on sale, remove option SHOWPLANE.
1251 * Stop ships, planes, land units and nukes on violent takeover, just
1253 * Wipe orders when ships, planes, land units and nukes are taken over
1254 violently or given away peacefully. Fleet, wing, army and mission
1255 were already cleared in many, but not all cases. Other orders were
1256 never cleared: mission op-areas (visible in xdump), ship autonav
1257 orders, ship sail path (including ship to follow and mobility
1258 quota), land unit retreat orders, plane range limit, and land unit
1260 * Fix takeover of stuff by attack, assault, board, lboard, paradrop
1262 - Corrupt land unit file could lead to infinite recursion.
1263 - Take over nuke armed on plane along with the plane. Broken in
1265 - Taking over land units with negative mobility increased mobility
1266 to zero. Ditto for planes embarked on ships or land units.
1267 * Fix a bug that made set and xdump not recognize unused trade lots
1269 * Fix giving away stuff by trading it:
1270 - When an armed nuke is sold separately from its plane, take it off
1271 the plane. You couldn't do that before 4.3.3.
1272 - Give away nuke armed on sold plane along with the plane. Broken
1274 - Don't zero mobility of planes and land units on sold ships.
1275 * Fix giving away stuff by unloading from its carrier: Give away any
1276 nukes armed on planes (broken in 4.3.3) and land units loaded on
1277 land units. The latter can't happen in the stock game.
1278 * Fix giving away stuff by scrapping or scuttling its carrier:
1280 - Disarm the nuke from a plane instead of destroying it.
1281 - Give away any loaded land units and planes, too.
1283 - Fix scuttle to ask for confirmation when scuttling a tradeship in
1284 an unsuitable sector even when the tradeship is pirated. Broken
1286 - Fix scuttle to require 2% harbor efficiency for a trade ship to
1287 pay. Also require at least friendly relations.
1288 - Make autonav refuse scuttle orders in unsuitable sectors.
1289 * Clean up rules on where you can scrap stuff:
1290 - Ships in own or friendly, efficient harbors (relations used not
1291 to matter, contrary to info)
1292 - Planes in own or allied, efficient airfields (friendly used to
1293 work as well, contrary to info)
1294 - Land units in any own or allied sector (relations used not to
1295 matter, and you couldn't scrap them on ships)
1296 Also tell player why something can't be scrapped instead of
1297 ignoring it silently.
1298 * Rewrite the broken code to move land units, planes and nukes along
1299 with their carrier. The old code was a hack that didn't update
1300 timestamps (so incremental dumps didn't pick up the movement), and
1301 it didn't cover all uses. The update, in particular, was prone to
1302 see cargo in old locations, which could screw up repairs.
1303 * Expire lost items at the update instead of continuously.
1304 * Replace econfig key lost_items_timeout by lost_keep_hours.
1305 * Minor Windows threading fixes.
1306 * Journal now uses human-readable names to identify threads.
1307 * Ship and land unit load counters are no longer stored in game
1308 state, because they duplicate information already there. Same for
1309 the type of nuke loaded on a plane. Remove field nuketype from
1310 xdump plane. Clients can simply find the plane's nuke instead.
1311 The edit command still accepts and ignores the plane key 'n' for
1312 compatibility, but it is deprecated.
1313 * Ship and land unit load counts as displayed by ship, sdump, land,
1314 ldump, ship selectors nplane, nxlight, nchoppers, nland, and land
1315 selectors nxlight, nland are now reliable. They used to get out of
1317 * Ship load counts now reflect what is loaded, not how it is stored.
1318 For instance, if a light carrier, capable of carrying 4 x-lights
1319 and 20 light planes carries nothing but 5 sams, we now have
1320 nxlight=5, nplane=0 instead of nxlight=4, nplane=1.
1321 * New cargo lists data structure to let code find loaded planes, land
1322 units and nukes easily and efficiently.
1323 * Revamped upkeep of lost file. It should be reliable now.
1324 * Disable the ill-advised error recovery on sector access that swept
1325 bugs under the carpet rather than recovering from them.
1326 * Occupied sectors no longer revert to the old owner when all
1327 military and land units go away. This feature was added in
1328 Chainsaw 3. It wasn't integrated properly with the che code
1329 (things went wrong when che killed all defenders, but couldn't
1330 convert the sector due to its loyalty), and combat code (if an
1331 attack killed off all local defenders and got defeated by reacting
1332 units, the sector changed ownership anyway, silently).
1333 * Include destination coordinates in interception and plane mission
1335 * Client could misdiagnose redirections and executes as unauthorized,
1336 or die outright. Broken in 4.3.11.
1337 * Fix xdump realm to dump player instead of absolute coordinates.
1338 Disclosed the true origin. Broken in 4.3.0.
1339 * Fix spy to reliably avoid spying same sector more than once.
1340 * The map drawing code could smash the heap when the world was
1342 * When a satellite's launch trajectory was off, its coordinates could
1343 get screwed up, which made it invisible in skywatch.
1344 * Fix several bugs that made the path command screw up when the path
1346 * Fix the default size of the map shown by move, test and transport
1348 * Fix bugs that could make arguments in area or dist syntax miss
1349 ships, planes, land units and nukes at the border of the selected
1350 area, if that area spans the whole world. In sufficiently small
1351 worlds, it could also make radar miss satellites and ships, sonar
1352 miss ships, satellite miss ships and land units, nuclear
1353 detonations miss ships, planes, land units and nukes, automatic
1354 supply miss ship and land unit supply sources, ships and land units
1355 fail to return fire, ships fail to fire support.
1356 * Maps sometimes showed x-coordinates as three lines instead of two
1358 * Improved nightly build, tests in particular.
1359 * Code refactoring and cleanup.
1361 Changes to Empire 4.3.16 - Sat Aug 9 15:56:52 UTC 2008
1362 * Production command incorrectly limited the number of graduates,
1363 happy strollers, technological breakthroughs and medical
1364 discoveries produced by a sector to 999. Broken in 4.2.15.
1365 * Fix a bug in improve that could let you spend more money than you
1367 * Fix work command not to spend more mobility than requested, and to
1368 round mobility use randomly instead of down.
1369 * Commands demobilize, convert and work no longer let you spend more
1370 money than you have. Commands demobilize and convert no longer ask
1371 for confirmation before spending more than half your money. Saving
1372 that feature would have been more work than it's worth.
1373 * Remove undocumented key 'd' at bomb ship, plane and land unit
1375 * Fix land unit flak when pin-bombed to match flak when overflown:
1376 proportional to efficiency, and randomly rounded. Was missed in
1378 * Don't permit bombing of embarked planes and land units.
1379 * Fix capital maintenance to charge at 60% efficiency.
1380 * launch command now requires only 40% plane efficiency, for
1381 consistency with other ways to launch missiles.
1382 * Disable collateral damage when automatically launched missiles miss
1383 their target. Collateral damage was done even when the launch
1384 failed or the missile got intercepted. It's been disabled for
1385 manually launched missiles since 4.0.18, for the same reason.
1386 * Fix a bug that corrupted the lostitems file. Broken in 4.3.12.
1387 * Show command changes:
1388 - Move product information from "show sect c" into new "show
1389 product", and reformat it to be easier to understand.
1390 - New column navigability in "show sect s".
1391 - "show sect s" now shows the packing bonus type instead of
1392 selected packing bonuses. "show item" shows the actual bonuses
1394 - "show sect b" now shows the usual values in addition to unusual
1396 * Fix interdiction to obey op-area for missiles.
1397 * Fix a bug that caused a stale sources.mk to be distributed in the
1398 4.3.14 an 4.3.15 tarballs. The latter does not build out of the
1399 box because of that.
1400 * Don't strip tab characters from quoted command arguments. Broken
1402 * shutdown commands now always take effect immediately. Before, they
1403 could be delayed by up to a minute.
1404 * shutdown could start multiple shutdown threads when you initiated a
1405 shutdown shortly after cancelling one. This screwed up the timing
1407 * Deity syntax of zdone changed, and is now documented in info.
1408 * The threshold command could be tricked into accepting negative
1410 * Fix designate to always write updated bmap to disk.
1411 * Fix bomb to fail on empty <pin|strat> argument instead of flying
1413 * Fix a bug in distribute that screwed up the current sector's
1414 distribution center when the command got aborted.
1415 * Commands arm, bomb, deliver, drop, fire, fly, paradrop, recon,
1416 lmine, order, power, range, sail, shutdown, sweep and tend did not
1417 honor command abortion at some prompts.
1418 * Fix a bug in handling of EOF from client that could bite in the
1420 - EOF at target prompts for bombing commodities, ships, planes and
1421 land units sent the server into an infinite loop that ate all
1423 - EOF at sail's path prompt crashed the server.
1424 - EOF at some prompts in deliver, designate, fly, morale, zdone,
1425 attack and assault didn't abort the command.
1427 * Selector terr is now the same as terr0 for mortal players, and
1428 dterr for deities. This matches how the territory command works.
1429 Unfortunately, this required us to rename xdump sect field terr to
1430 terr0. Sorry about that.
1431 * Fix bomb not to let you bomb dead ships and land units.
1432 * Make the retreat command a bit more helpful on retreat conditions,
1433 and make it fail on bad conditions.
1434 * Fix the mapper scripts. Broken in 4.2.0.
1435 * Fix flying commands not to let planes do double duty as escorts.
1437 * When a minesweeper hit a mine after sweeping, the mine wasn't used
1438 up. If it sank the minesweeper, the code accessed freed memory,
1439 which could clobber the ship file or worse. Broken in 4.0.17.
1440 * Don't let non-light units board ships that can't carry them.
1441 * Capitals can now employ up to 1000 civilians instead of 999.
1442 * Spy command changes:
1443 - Spy now requires sector military. Before, presence of land units
1444 was sufficient, but spies shot were only deduced from sector
1445 military. If you lost more spies than you had sector military,
1446 the rest came back from the dead.
1447 - Spy no longer ignores non-sea sectors without civilians, military
1449 - Remove columns lnd, pln from spy report. The values didn't match
1450 the reported land units and planes, and could leak the presence
1452 - Establish contact when spy succeeds even though the spy was
1454 * Fix news reporting and damage when land units interdict ships in
1455 sectors other than sea.
1456 * Fix land unit return fire damage to ships to take accuracy into
1457 account, like the fire command and interdiction does.
1458 * Remove the inconsistent shelling damage reduction for range. Fire
1459 command got damage reduced by 10-20% with a chance depending on
1460 range ("Wind deflects shells"). Ships interdicting got it reduced
1461 by half. Other ways to shell did not get damage reduced for range.
1462 * Fix ground combat to report defending land units. Broken in 4.3.4.
1463 * Info file and documentation fixes and improvements.
1465 Changes to Empire 4.3.15 - Sun May 18 08:59:30 UTC 2008
1466 * The edit command keys deprecated in 4.3.10 are now gone.
1467 * fairland now obeys game file locks.
1468 * Do not leak world creation time in files utility, because that
1469 facilitates attacks against fairland's PRNG. Broken in 4.3.12.
1470 * Fix starvation not to starve one more than it should. The last man
1471 on a boat or land unit now can't starve anymore.
1472 * Fix a crash bug in satellite. Broken in 4.2.7 and not fixed
1473 correctly in 4.2.12.
1474 * Fix a coordinate normalization bug that could theoretically lead to
1475 buffer overruns and other unpleasantness. None have been
1476 reproduced, though. Broken in 4.3.12.
1477 * Remove option FUEL. The abstract idea of tying ships and land
1478 units to a logistical tether is sound, the concrete implementation
1479 as option FUEL is flawed. It adds too much busy-work to the game
1480 to be enjoyable. It hasn't been enabled in a public game for
1481 years. The code implementing it is ugly, repetitive, and a burden
1482 to maintain. The edit command still accepts and ignores the fuel
1483 keys for compatibility, but they are deprecated.
1484 * Fix pin-bomb not to report subs when there are none.
1485 * You now have to take a capital to capture the victim's money, loans
1486 or market lots. Merely obliterating the capital doesn't cut it.
1487 It still makes the victim lose money, though.
1488 * Fix a bug that could theoretically allow sacking of non-existant
1489 capitals of visitors, deities and such.
1490 * You now gain BTUs and MOB_ACCESS mobility before the first update
1491 again. You didn't since 4.3.10 introduced the ETU clock.
1492 * Fix edit to detect when the edited object changes while it's being
1494 * Fix xdump nat for relations: it got HIDDEN backwards. Broken in
1496 * Fix origin command not to prompt twice for its argument. Broken in
1498 * Info file improvements.
1500 Changes to Empire 4.3.14 - Mon May 5 04:57:03 UTC 2008
1501 * Another round of fixes to the fire command:
1502 - Don't disclose where the target retreated to.
1503 - Charge the target shells for returning fire.
1504 - Always use guns when the target is out of range, even if it's a
1505 submarine. Before, the difference in shell use disclosed whether
1506 the target is a submarine. Loophole opened in 4.3.12.
1507 - Make depth charges again work with just one shell. Failing the
1508 command in that case lets players find out whether the target is
1509 a submarine. Loophole opened in 4.3.12.
1510 - Detect when the firing sector, ship or land unit changes across
1511 the target prompt. Can be abused to duplicate commodities, and
1513 * Fix parsing of anchor-relative time in update schedule. Broken in
1515 * Fix logging of player input in the journal to include command
1516 interruption and EOF.
1517 * Fix oversights in 4.3.12's change to keep track of flying planes:
1518 planes could be erroneously reported damaged by their own ground
1519 strikes. Happened with missions and the launch command.
1520 * Fix load not load hardened missiles.
1521 * Fix harden not to harden missiles loaded on land units.
1522 * New server option -E to choose what to do on recoverable internal
1523 error. You can now make the server dump core and keep going (not
1524 implemented for Windows). New econfig key post_crash_dump_hook to
1525 run a program after crash-dumping. See scripts/savecore for an
1527 * Journal entries are now flushed to disk right away even when the
1528 server is not running in debug mode.
1529 * Don't let land units load trains.
1530 * Allow deity to display power report for all types of countries,
1532 * Fix designate's check for disallowed sector types. Broken in
1534 * Documentation fixes.
1536 Changes to Empire 4.3.13 - Tue Apr 15 19:03:11 UTC 2008
1537 * Work around strptime() lossage on some systems. Fixes the parsing
1538 of the schedule file there.
1539 * New selector maxnoc for xdump version.
1540 * Fix initialization of realms in newcap. Broken in 4.3.12.
1541 * Fix add for status arguments active, god, delete. Broken in
1543 * Info file, manual page and documentation fixes.
1545 Changes to Empire 4.3.12 - Wed Apr 2 05:35:06 UTC 2008
1546 * Fix rounding error in update that could result in more babies than
1547 food permits, and negative food.
1548 * Fix a bug that could lead to unfair thread scheduling under
1550 * Fix ship and land unit missile interdiction and ballistic missile
1551 interception to require a proper base. Before, missiles could
1552 launch from anywhere for that.
1554 - Don't allow launching from unowned sectors.
1555 - Don't destroy missiles stuck on foreign ships.
1556 - Use up the supplies required for launching an asat only when it
1558 - Don't ignore satellites' fuel use.
1559 * Deity command newcap now requires its second argument (sanctuary
1560 coordinates). Before, it tried to pick a suitable location when
1561 none was given. The code implementing this feature had problems,
1562 and it's not worth fixing, because it is obscure, and rarely (if
1563 ever) used: no conscientious deity would use it for a real game,
1564 and for blitzes fairland does a better job.
1565 * Keep track of flying planes properly. This fixes a number of bugs:
1566 - While the bomb command awaited pin-bombing target input from the
1567 player, other players could interact with the pin-bombers and
1568 escorts as if they were sitting in their bases: spy them, damage,
1569 capture, load, unload, or upgrade them, even get intercepted by
1570 them. But any changes to those planes were wiped out when they
1572 - The bomb command could bomb its own escorts, directly (pin-bomb
1573 planes) or through collateral damage, strategic sector damage,
1574 collapsing bridges or nuke damage. The damage to the escorts was
1575 wiped out when they landed.
1576 - If you asked for a plane to fly both in the primary mission and
1577 escort, you got charged fuel for two sorties instead of one.
1578 * Plug memory leaks in plane interception.
1579 * Fix trade not to let the buyer teleport satellites (not in orbit)
1580 and asats to an arbitrary sector. Abusable, because abms
1581 intercepted from anywhere, and satellites could be launched from
1583 * The PRNG seed is now logged in the journal.
1584 * Fix nightly build for Windows.
1585 * Fix crash bug that bit when custom tables contained columns names
1586 that existed, but weren't supposed to be in the custom table.
1587 * New timestamp selector for commodity, country, game, loan, nation,
1588 news, realm, trade, treaty to support incremental xdump.
1589 * Deity commands newcap and add wipe the nation more thoroughly. add
1590 no longer touches relations and flags for status active and god.
1591 * New utility program empdump to export and import game state as
1592 plain text. Check its manual for details, including limitations.
1593 * Plane, ship and land unit stats are no longer stored as game state,
1594 but recomputed from tech and base stats as needed.
1595 * xdump ver is no longer a special case. Syntax "xdump ver" is now
1596 deprecated. Use "xdump version *".
1597 * Fire and torpedo cleanup and bug hunt:
1598 - Plug memory leak in fire command.
1599 - Fix ammunition use when returning fire: resupply could lose
1600 shells when returning fire to multiple targets, and land units
1601 were charged per target instead of just once.
1602 - Interdicting land units now resupply shells automatically, for
1603 consistency with other ways to fire.
1604 - torpedo and fire no longer resupply shells automatically. The
1605 latter used to resupply land units only.
1606 - Land units no longer have to be in supply to fire actively, for
1607 consistency with other ways to fire.
1608 - Submarines with zero mobility can no longer interdict, for
1609 consistency with other ways to torpedo.
1610 - Fix bugs that let submarines without capability torp use
1611 torpedoes to return fire and interdict.
1612 - Fix torpedo command not to require a line of sight for return
1613 fire and depth charges, and to use torpedo range instead of
1614 firing range for return torpedoes.
1615 - Active fire and interdiction didn't work for ships with zero
1616 firing range, even though return fire and support did. No such
1617 ships exist in the stock game.
1618 - Let land units with zero firing range and non-zero firing damage
1619 fire, for consistency with ships. No such units exist in the
1621 - Ships required different numbers of military to operate their
1622 guns for the various kinds of fire. Unify to require 2*N-1
1623 military to fire N guns.
1624 - Ship ammunition use differed for the various kinds of fire.
1625 Unify to use one shell per two guns.
1626 - Forts could fire support even when there were not enough mil.
1627 - Fix automatic shell resupply in several places to supply exactly
1628 the shells actually fired, no more, no less.
1629 * Change depth charges back to how they are documented and worked
1630 before 4.0.6, mostly: require no guns, one military, do damage like
1631 shell fire from three guns (before 4.0.6: two guns), use two
1632 shells. In 4.0.6's model, they worked exactly like shell fire
1633 (require guns and gun crew, non-zero firing range, damage and
1634 ammunition use scales with available guns), except for missions,
1635 which was a bug. Note that depth charge damage for all ships is
1636 now like fire from three guns for two shells. No change for dd; af
1637 did two gun damage for one shell before, and nas did four gun
1638 damage for two shells.
1639 * The edit command keys deprecated in 4.3.3 are now gone.
1640 * Fix build not to screw up automatic dependencies on certain compile
1642 * Fix a bug that could prevent repeated news from properly
1643 aggregating into one news item.
1644 * Properly initialize all bits in game state files, even those that
1646 * Fix explore's test for stopping on a splashed bridge. The bug made
1647 explore print to a bogus message.
1648 * Fix spelling of symbol airburst in table plane-flags. This could
1650 * Change designate not to check total cost before executing the
1651 redesignation. The code implementing that was buggy and too ugly
1652 to live. Designate doesn't cost anything in the stock game.
1653 * Always charge land units at least as much mobility for assaulting
1654 from non-landing ships as from landing ships. Before, marines lost
1655 all mobility when assaulting from a non-landing ship, which could
1656 be less than what the same assault costs from a landing ship (half
1658 * Fix LWP's stack initialization for -s. It caused crashes on some
1660 * Fix confused and buggy bridge splashing code:
1661 - Flying planes could be reported drowned.
1662 - Pin-bombing a bridge head failed to collapse bridge spans for
1663 lack of support, unless the pin-bombing caused collateral damage.
1664 - Corrupt sector file could lead to infinite recursion.
1665 * Relative names now work for econfig keys data and info.
1666 * Fix utility programs to abort on internal errors. They used to
1667 print a message and attempt to recover.
1668 * Fix off-by-one in fairland that ate the last expansion island.
1669 * Switch from CVS to git.
1670 * Code refactoring and cleanup.
1671 * Portability fixes.
1672 * Info file, manual page and documentation fixes and updates.
1674 Changes to Empire 4.3.11 - Tue Jan 1 18:57:38 UTC 2008
1675 * New sector selector elev. It's set by fairland, but has no effect
1676 on the game. It can be useful for deities to customize a world
1677 created by fairland.
1678 * The client now copes with ids greater than 15. The Empire
1679 protocol currently uses 14 ids.
1680 * Rewrite the client's code for reading server output during login.
1681 The old code could write one byte beyond the end of the buffer
1682 (theoretically a remote hole), got confused by long lines, and
1683 lines that didn't arrive in one piece.
1684 * Long country name, password or user name crashed the client.
1685 * Fix xdump not to deny access to game state tables when maximum
1686 minutes per day are exceeded.
1687 * The server considers a country bankrupt when its treasury is
1688 negative. Except when it doesn't. Fix that:
1689 - report misreported countries with $0 as broke.
1690 - If a command spent a few cents more than you had, commands requiring
1691 money became unavailable even when rounding brought you back to
1692 $0. But logging out and back in then bankrupted you.
1693 - If your treasury rose to exactly $0, commands requiring money
1694 remained unavailable.
1695 - If you had $0, sectors didn't build and sectors and ships didn't
1696 produce at the update.
1697 * Fix a bug in trade that made your money evaporate when a trade fell
1698 through because you couldn't fully pay. This bug was there since
1699 the introduction of the market in 4.0.0. It got aggravated by the
1700 removal of forced loans in 4.3.0.
1701 * Fix printing of the new group in army, fleet and wing. Broken in
1703 * Fix flash not to screw up the message when the first argument
1704 contains white-space.
1705 * Don't let planes intercept when they are stuck in foreign bases, on
1706 inefficient ships or land units, or on land units loaded on ships
1708 * Fix a bug that made interception require petrol to be present even
1709 for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
1710 defense missions weren't affected.
1711 * fairland and setsector now limit fertility to 100 instead of 120,
1712 like the other resources.
1713 * Generalize the autonav hack for fishing boats so it covers oil
1715 * Fix bug in path command that made it swallow every other step.
1717 * The execute command no longer supports redirections and execute in
1718 batch files. Flaws in the Empire protocol make it next to
1719 impossible for clients to implement that correctly. See
1720 doc/clients-howto for an explanation.
1721 * Rewrite much of the client's code for sending commands and
1722 receiving server output:
1723 - No longer blocks on sending commands, which could deadlock the
1725 - Fix race condition that could cause server output to be discarded
1726 on EOF on standard input.
1727 - Don't discard server output when reading standard input fails.
1728 - Fix error handling for execute and other, more obscure cases.
1729 - More rigorous error checking for redirections and execute.
1730 Clearer error messages, too.
1731 - Fix execute redirected to file or pipe. Believed to be broken in
1733 - The client now creates files for redirections with the same
1734 permissions whether the redirection is in a pipe or not. Before,
1735 redirections without a pipe created files with no permissions for
1736 group and others. This change may make your redirected output
1737 visible to other users on your system. Use the usual controls,
1738 like umask, to restrict permissions to your liking.
1739 - Reject unexpected redirections (violating the protocol). Before,
1740 they silently replaced the current one, and in the case of pipes
1741 leaked file descriptors and memory.
1742 - Redirections in batch files are not implemented. They didn't
1743 quite work before, and could leak memory and file descriptors. A
1744 flaw in the Empire protocol makes them next to impossible to
1745 implement correctly.
1746 - The execute command in batch files is not implemented. A flaw in
1747 the Empire protocol makes this practically useless anyway.
1748 - Old code leaked memory in various places.
1749 - Unfortunate incompatibility with older servers: if you type the
1750 EOF character (normally ^D) at an argument prompt, the session
1751 hangs. Use the interrupt character (normally ^C) to get out.
1752 * The client now supports options -h and -v.
1753 * The client no longer zaps its command line in a lame attempt at
1754 protecting users who foolishly specify passwords on the command
1755 line. Zapping annoys system administrators and creates a false
1757 * Journal entries are now flushed to disk right away when the server
1758 is running in debug mode.
1759 * Fix bugs in load that could make loading operations fail noisily
1760 instead of silently on some systems.
1761 * Server now reliably shuts down session when it receives an
1762 end-of-file condition from the client. Before, it merely failed
1763 the current command when it got it at an argument prompt.
1764 * Fix bug in execute that could crash the server on some systems when
1765 it prompts for the argument.
1766 * Fix bug that let you check whether a non-allied carrier is
1767 efficient enough for takeoff when one of your planes got stuck
1769 * Fix bug that let you attempt to escort a one-way mission to a
1770 carrier with non-light, non-interceptor escorts. Such planes don't
1771 fit on carriers, and the command then failed with a bogus error
1772 message. Before 4.2.17, the planes flew, and the escorts were
1774 * Change the rules for fitting planes on ships slightly, so that the
1775 order of loading no longer matters. Choppers and x-lights can now
1776 use plane slots even when not light. X-light choppers, which don't
1777 exist in the stock game, can no longer use x-light slots.
1778 * The server now keeps its log file open, just like the journal.
1779 * New server option -R to set the PRNG seed. This is for
1780 reproducible tests. Change the Windows-only service uninstall
1781 options from -r/-R to -u/-U.
1782 * Supply a real PRNG for Windows instead of the leaky water-pistol
1784 * Threads sleeping until a specified time could return early under
1785 Windows. This could cause missed updates. Broken in 4.3.10.
1786 * Fix missing newline in show updates.
1787 * Power report didn't factor tech into power correctly. Broken in
1789 * Code refactoring and cleanup.
1790 * Info file and documentation fixes and updates.
1792 Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
1793 * Bridge spans now cost $1000 instead of $2000, and bridge towers
1794 $3000 instead of $7500.
1795 * The Windows port now supports IPv6, but it still needs to be
1796 enabled manually at compile-time.
1797 * The custom table reader detects more errors.
1798 * Do not leak world creation time in files and fairland, because
1799 that facilitates attacks against the PRNG. This misfeature crept
1801 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
1802 Using it required manual hackery since 4.3.0.
1803 * Plug file descriptor leak in add command.
1804 * Don't kill player connections violently when their thread appears
1805 to be hung. Threads being aborted by update or shutdown could be
1806 misidentified as hung, and the violence could lead to resource
1807 leaks, locked out updates, and corrupted game state.
1808 * Fix LWP to reliably wake up threads sleeping for a time. Before,
1809 players with a sufficiently fast connection could starve out system
1810 threads, including the update.
1811 * Fix a class of bugs that made commands behave differently while the
1812 update is attempting to take control:
1813 - No MOB_ACCESS mobility was gained.
1814 - Telegrams were miscounted.
1815 - Bulletins got misfiled as production reports.
1816 - The navigate command ignored sail paths.
1817 - The declare command was more quiet, and declarations of war
1818 failed silently when SLOW_WAR was enabled.
1819 - Many messages got misdirected to bulletins.
1820 Some of these bugs go back all the way to Empire 2, ca 1995.
1821 * New deity command reload, effect similar to SIGHUP.
1822 * Not voting for a demand update no longer lets you veto further
1823 demand updates. This feature was flawed (it encourages players to
1824 vote late so that they can tactically vote no and thus build up
1825 veto rights), virtually unused, and buggy. The edit command still
1826 accepts and ignores the country key 'U' for compatibility, but it
1828 * Fix zdone not to claim to have triggered an update when they're
1830 * New update scheduler and ETU clock:
1831 - New schedule file. See doc/schedule for how to use it. Replaces
1832 econfig keys update_policy, adj_update, update_times, hourslop,
1833 blitz_time. A change of schedule does not require a server
1835 - The force command can no longer force updates in the future.
1836 Edit the schedule file for that.
1837 - New command show updates to show the update schedule. Obsoletes
1839 - New xdump game and xdump updates.
1840 - New utility program empsched to help test update schedules.
1841 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
1842 by econfig key update_demand.
1843 - econfig key update_demandtimes no longer applies to scheduled
1845 - You now receive new BTUs at the update in addition to login.
1846 - You now always gain the same BTUs and MOB_ACCESS mobility per
1847 turn, even when the update schedule changes, updates get missed,
1848 or unscheduled demand updates run.
1849 - Remove the mobupdate command, because porting it to the new ETU
1850 clock is not worth it.
1851 * Redesign of synchronization between commands, update and shutdown,
1852 and how updates are triggered:
1853 - Simplify update to a single thread waiting for the trigger.
1854 Before, three update threads had to perform a carefully
1855 choreographed dance to make updates happen. The dance relied on
1856 thread priorities for correctness, which are only implemented by
1857 LWP. With pthreads and under Windows, demand updates were prone
1858 to two update threads starting up concurrently. Even with LWP,
1859 forced and demand updates could lead to double updates.
1860 - Use a lock for synchronization: commands take it shared, update
1861 and shutdown take it exclusive. This makes update and shutdown
1862 block until all aborted commands terminated and gave up their
1863 lock. Before, they proceeded blindly after waiting two or one
1864 seconds respectively, which was cheesy and unsafe.
1865 - New commands no longer fail while the update is pending, they are
1866 delayed until after the update.
1867 - New commands can no longer start during shutdown. Before, they
1868 could, but risked getting killed violently, possibly corrupting
1870 - Fix command execution so that commands blocked in writing
1871 redirections are abortable. The bug allowed players to delay
1872 update and shutdown indefinitely.
1873 - Fix shutdown not to let player threads block on output. This
1874 let players delay shutdown indefinitely.
1875 - Fix reading of player input not to block again after update or
1876 shutdown aborted it. The bug allowed players to delay update and
1877 shutdown indefinitely.
1878 * Thread priorities are only implemented by LWP and no longer used.
1879 With LWP, they let players with a sufficiently fast connection
1880 starve out the threads that clean the lost file and kill idle
1881 connections. Drop them.
1882 * Show nuke rounded required research incorrectly.
1883 * Log unprintable characters as octal escapes rather than question
1884 marks in the journal file.
1885 * The files program no longer changes permissions of existing files.
1886 * The files program now creates all files with permissions ug=rw and
1887 all directories ug=rwx, modified by umask.
1888 * Fix a bug that could make arm, disarm and nuke detonation work with
1889 a used-up nuke instead of the armed one. This could be abused to
1890 detonate nukes multiple times. Broken in 4.3.3.
1891 * Fix nuke detonation output for zero blast radius.
1892 * Plug memory leaks in thread code.
1893 * Fix a bug that made LWP I/O wakeup unreliable.
1894 * New march sub-command v for view.
1895 * Journal was initialized before threads were, which was wrong.
1896 * Fix server not to create a journal on SIGHUP when it is disabled.
1897 * shutdown 0 now requests immediate shutdown instead of cancellation
1898 of a pending shutdown. shutdown -1 now cancels.
1899 * flash and wall no longer split long message lines.
1900 * Fix a bug in collect that screwed up a fully collected loan instead
1901 of deleting it. The screwed up loan could not be sharked or
1902 collected, but it could be repaid.
1903 * Remove the wait command, it's been broken and restricted to deity
1904 since Empire 2, ca. 1995.
1905 * Budget failed to take sector production into account for predicting
1906 unit repairs. Before 4.3.6, this bug bit only when you fooled
1907 around with budget priorities.
1908 * When unit repairs are limited by materials, the efficiency gain is
1910 * Ship repairs outside harbors and plane repairs by carriers used to
1911 consume commodities when and as far as available. Now, they
1912 consume the same fraction of the real cost of each commodity,
1913 i.e. commodity use is limited by the most scarce commodity.
1914 Neither old nor new behavior make much sense, but the new code is
1916 * Code refactoring and cleanup, in particular to make the Windows
1918 * Portability fixes.
1919 * Info file and manual page updates. All manual pages are now
1920 installed in section 6.
1922 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
1923 * Fix declare to prevent the deity from changing relations for a
1924 player to self. Allow the deity to set the relations of a player
1926 * Fix arm not to put the same nuke on multiple planes (broken in
1928 * New option AUTO_POWER.
1929 * Sectors now repair allied land units.
1930 * Sectors now repair only own and allied planes.
1931 * Fix repair of planes on foreign carriers: repair allied planes,
1932 ignore the others. Before 4.3.3, carriers destroyed rather than
1933 repaired foreign planes. Since 4.3.3, foreign planes were treated
1934 as recoverable error.
1935 * Fix automatic fortification of land units to use all excess
1936 mobility even when mobility delta exceeds mobility maximum.
1937 * Disable automatic fortification of land units when MOB_ACCESS is
1938 on, because it is prohibitively slow then (broken in 4.2.13).
1939 * Budget now shows level production (tech, education, research and
1940 happiness) rounded instead of randomly rounded.
1941 * Fix update not to randomly flush small level production to zero.
1942 * Fix overly restrictive game file locking under Windows (broken in
1944 * Fix navigate to charge mobility for sweeping mines without moving
1948 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
1949 * Ships no longer produce stuff when the government is broke.
1950 * Fix land unit casualties in revolts.
1951 * Fix security units not to raid friendly che.
1952 * Fix update sequence to ensure stopped sectors don't work on the
1953 ships, planes and land units in the sector. Before 4.3.6, this bug
1954 bit only when you fooled around with budget priorities.
1955 * Fix canal loading (was broken in 4.3.0).
1956 * Fix tend not to tend land units that could not be loaded.
1957 * Make xdump command available before break, but deny access to game
1959 * Lock game files to prevent concurrent access by multiple programs.
1960 fairland does not yet obey the lock.
1961 * Fix production to consider sector item limit.
1962 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
1963 * Enhanced mapping sub-commands in move, test, explore and transport.
1967 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
1968 * Sanctuaries are again fully populated with civilians (4.3.6 changed
1969 the limit, but not the population). Food is now spread evenly
1971 * Fix path finder to find shortest naval and aerial paths again
1973 * transport's map sub-command now does the right thing for a unit
1975 * Fix bug in map sub-command of move, explore and transport that
1976 passed junk to map command. Could theoretically crash.
1977 * Food need reported by starvation was one short for sectors without
1979 * Change land unit ammunition use back to what it was before 4.2.3.
1980 This lets deities customize ammunition use independent of damage.
1981 It also substantially reduces ammunition consumption at high tech.
1982 * navigation and march enhancements:
1983 - Sub-command 'f' now takes an optional ship / land unit number.
1984 - Mapping sub-commands now take an optional ship / land unit
1986 - New sub-command 'd' to drop mines.
1987 * Let minesweepers retreat at their full speed (missed in 4.3.6).
1988 * SUPER_BARS cannot be harmed, so don't interdict them.
1989 * Don't let trains and non-trains march together for now, because the
1990 march code isn't prepared for that.
1991 * New mapping flag 'n' to show nukes.
1992 * Mapping flag '*' now shows nukes as well.
1993 * New command nbmap to bmap around a nuke. Overload command nmap to
1994 map around a nuke when given a nuke argument.
1995 * Fix an inconsistency that gave tactical bombers a small bonus
1996 vs. flak when pin-bombing.
1997 * Fix production to show the designation that actually produces, not
1998 the designation as it is now (broken in 4.3.6).
1999 * Fix accidental whitespace change in output of sdump, pdump and
2000 ldump that crept into 4.3.5.
2001 * Support user-defined sector types and products in custom tables,
2002 not just customization of existing ones.
2003 * Fix off-by-one bug in budget that used to be masked by budget
2004 priorities until their demise in 4.3.6. The bug could crash the
2005 game on certain systems.
2009 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
2010 * The shutdown command now terminates the server process correctly
2011 even with LinuxThreads pthreads under Linux 2.4 and earlier.
2012 * Cope with old versions of groff (broken in 4.3.0).
2013 * You can now arm allied planes with nukes.
2014 * Taking a nuke off a plane gives it to the sector owner again.
2015 Feature was accidentally dropped in 4.3.3. Recipient must be
2017 * Naval path went bananas for impassable end sectors (broken in
2019 * New econfig key disabled_commands.
2020 * New territory selector dterr, restricted to deities. The territory
2021 command defaults to it for deities.
2022 * Let land units attack as long as they have positive mobility,
2023 except for high-mobility terrain (mountains), where the rules
2024 remain as they were: land units need to have all the mobility
2025 charged for the attack, not counting combat and moving in to
2026 occupy. Rationale: Making sure your land units reach attack
2027 positions with enough mobility left is a pain in the neck.
2028 Requiring only positive mobility is friendlier, but allowed rushing
2029 of mountains, so we make an exception there.
2030 * Can typeset info pages as PostScript. Result isn't exactly pretty.
2031 * Support disabling of infrastructure in infra custom table. Remove
2032 redundant option DEFENSE_INFRA. show command now shows only enabled
2034 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
2035 pmap sbmap, smap (broken in 4.3.1).
2036 * New, simpler sector mobility cost formula:
2037 - The basic cost is still a linear function of sector efficiency,
2038 with customizable cost at 0% and at 100%. The latter used to be
2039 derived from the former. The show command shows both parameters
2041 - Mountains are no longer a special case.
2042 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
2043 to 1.304, highway, bridge head, bridge span and bridge tower
2044 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
2045 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
2046 players can designate now cost the same at 0%. That's a feature.
2047 - Road infrastructure now reduces cost up to 90%, linear in road
2048 efficiency (used to be close to that, but non-linear). Same for
2049 rail infrastructure, but 99%. Adapted from Ice World V.
2050 - Double land unit minimum cost to 0.02, to slow them down on
2052 - Change land unit cost penalty in newly taken land to an extra 0.2
2053 instead of a minimum of 0.2, to reduce penetration depth.
2054 * Reduce bridge head defense and collect value to match highway's.
2055 * sinfrastructure displayed bogus rail mobility costs when there was
2057 * Retreating engineers took full landmine damage instead of half.
2058 * Fix socket creation code not to print a null pointer.
2059 * Fix login option code not to search beyond end of table (broken in
2061 * Spy planes and satellites can no longer spot landspies.
2062 * Spy planes can now spot surface ships at sea. They can no longer
2063 spot land units loaded on ships or land units.
2064 * Fix train retreat mobility cost, and don't permit retreat off rail.
2065 * Change maximum population to 100 for plains (was 49), mountains
2066 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
2067 the other habitable sector types (was 999).
2068 * Let minesweepers navigate at the speed their stats indicate by
2069 letting them sweep on the move at no extra mobility charge.
2070 * Reduce chance for planes to abort from 100-eff (if eff<80) to
2071 80-eff. This should make it easier to punch through air defense,
2072 flak in particular, and increase the risk of getting shot down.
2073 * Ship and land unit flak intensity is now proportional to efficiency.
2074 * Ship and land unit flak intensity is no longer scaled by the tech
2075 of the owner of the last thing firing. It's still scaled by each
2077 * All ships and land units firing flak now spot the plane and are
2078 spotted by the plane. Previously, spotting stopped as soon as flak
2080 * Inefficient land units were overcharged mobility when reacting.
2081 Broken when Empire3 changed land unit mobility use not to depend on
2082 efficiency, except for supply units.
2083 * New journal file to log complete player input plus selected
2084 important events. Controlled by new econfig key keep_journal, off
2086 * Fix unsafe shutdown on SIGINT and SIGTERM.
2087 * Fix land unit path finding: paths weren't always cheapest (broken
2088 in 4.0.2), and trains could be sent down paths without rail (never
2089 worked). Also fixes unit reaction path cost.
2090 * The custom table reader can now deal with sector, item, product and
2091 infra tables more comfortably.
2092 * Remove option BIG_CITY. Deities can customize the sect table to
2093 get the same effect.
2094 * Many more selectors can now be compared with names, not just
2095 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
2096 not fully work for queer names like &&&.
2097 * Let land units on missions support, just like ships.
2098 * Don't let units loaded on a train react.
2099 * Change update sequence to repair ships, planes and land units after
2100 sectors produce. This makes repairs use new avail instead of old.
2101 * Let players stop and start units.
2102 * Remove budget priorities.
2103 * Make plane report easier to understand.
2104 * Change land report to show carriers in the same format as plane and
2107 * Info file and manual page fixes.
2109 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
2110 * In conditionals, ~ compared to a string selector now stands for an
2112 * Change encoding of `not in any group' from " " to "". This makes
2113 fleet=~ work. It also affects xdump.
2114 * Fix plane capture code to clear wing.
2115 * People now eat and starve exactly the same in sectors, ships and
2116 land units. There used to be small differences, and civilians and
2117 uw loaded on land units didn't eat at all. The starvation command
2118 has been updated accordingly.
2119 * Fix bug that makes it impossible to assault or board with land
2120 units (broken in 4.3.4).
2123 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
2124 * Don't use non-portable groff features (broken in 4.3.0).
2125 * Work around potential crash bugs in command argument access.
2126 * Plug major information leak through nation selectors (broken in
2127 4.2.21). The fix unfortunately exchanges the meaning of xdump
2128 nation and xdump country. Sorry about that.
2129 * Minimize redundancy between (mortal's) xdump nation and xdump
2131 * New nation selector rejects.
2132 * xdump nation now shows foreign relations and no longer discloses
2134 * Fix crash bug in edit.
2135 * Fix number of planes building in budget command (broken in 4.3.3).
2136 * Selectors group, fleet, wing and army are now strings, and obvious
2137 syntax like fleet#a works. xdump also shows the strings now.
2138 Units not assigned to a group currently have group string " ", but
2139 that may still change.
2140 * Don't fold conditionals to lower case, because it breaks valid
2141 conditionals like fleet#A.
2142 * Mobility cost of a plane sortie is no longer limited to current
2144 * Various formulas no longer truncate or round intermediate results.
2145 * Interdiction mission charged twice the normal mobility cost for
2147 * Fix sail not to interpret negative x-coordinates as unsail
2149 * Improved configure script.
2152 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
2153 * power c can now show powerless countries. power c * works.
2154 * Fortresses now require 5% efficiency to return fire and interdict.
2155 * Range of ship return fire and support fire no longer depends on
2157 * Fix heap smash in login command client. Remote hole!
2158 * Properly destroy nukes on collapsing bridges. Before, you could
2159 rescue them by building a new bridge or arming them on naval
2161 * Nukes are now numbered like other units:
2162 - New selector type replaces selectors number and types.
2163 - New selector plane points to plane armed with this nuke.
2164 - New selectors effic, mobil, tech, group, opx, opy, mission,
2165 radius. Provided because all units have them; values are
2166 currently not interesting.
2167 - nuke command output redesigned.
2168 - ndump output changed subtly: nukes are no longer sorted by
2169 location, nukes in the same location no longer share id, and
2170 nukes on planes are shown.
2171 - transport nuke now works like transport plane.
2172 * arm and disarm now accept the common plane syntax, not just plane
2174 * Fix arm to let you change an armed plane's air-burst/ground-burst
2176 * territory no longer re-prompts when supplied with a bad argument,
2178 * edit lets you edit stuff that is actually computed from other
2179 state, like sector's coastal flag. This makes no sense and is now
2180 deprecated. Stuff deprecated since 4.2.15 is now gone.
2183 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
2184 * Fix security units' raid at the update (broken in 4.0.0, fixed only
2185 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
2186 increase. Make sure empty units don't kill anyone.
2187 * Fix bug in player_init(), which was most likely fatal on 64 bit
2188 hosts. Broken in 4.3.0.
2189 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
2190 * The order in which sectors were visited for `*' arguments disclosed
2191 the real origin, fix. Mapping commands used to work around this
2192 bug, until 4.3.1 exposed it there as well.
2193 * Code didn't compile on some systems.
2194 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
2196 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
2197 * Fix check of game state on server startup (new in 4.3.0).
2198 * sail now accepts a destination sector.
2199 * Tend could send bogus bulletins (broken in 4.3.0).
2200 * Plug memory leaks in mission command.
2201 * Close loophole in navigate that allowed players to find all sectors
2202 that are unfriendly or inefficient harbors or bridges.
2203 * Server didn't start when default econfig was missing and user
2204 didn't supply one with -e (broken in 4.3.0).
2205 * Retreat condition 'h' (helpless) never worked, fix.
2206 * Fix retreating mine sweepers to use mobility for sweeping.
2207 * Fix retreating land units to hit mines with the same probability
2208 and to take the same damage as in normal movement. Before,
2209 hit probability was higher, and damage was lower.
2210 * Ships could retreat into sectors owned by whoever made them
2211 retreat, but not in their owner's sectors.
2212 * Fix 'm' at the movement prompt of transport and test.
2213 * Fix march and test not to apply conditionals to sectors mapped,
2214 which led to spurious error messages.
2215 * Fix break not to respect conditionals. The bug let players keep
2217 * Fix retreat code not to respect conditionals. Attackers could
2218 abuse this to suppress fleet and army retreat orders.
2219 * Fix retreat and edit to zero-terminate retreat paths.
2220 Theoretically abusable for gaining information.
2221 * Fix format string crash bugs in load, spy and bomb.
2222 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
2223 ~p before the first line of text never worked.
2224 * Fix ancient bridge building race condition that could break the
2225 test whether the player can afford the bridge.
2226 * Fix trade lot change detection in set command. Can probably be
2227 abused to defraud sellers.
2228 * The pthread code now compiles under Solaris.
2229 * navigate and march now permit any whitespace between route and
2230 optional argument for radar, lookout, sonar, not just spaces.
2231 * Fix canal navigation (was broken in 4.3.0).
2234 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
2235 * version no longer pretends option SHIPNAMES still exists.
2236 * Remove files auth and ban. They could be used to restrict client
2237 address and user. Restricting user is useless, because players can
2238 send whatever they want. Banning IPs is better done with a packet
2239 filter. That leaves restricting deity IPs. Provide new econfig
2240 key privip for that. Apply it to session kill as well as login.
2241 * xdump escapes GUINEA_PIGS status:
2242 - xdump is now enabled unconditionally.
2243 - xdump sect now dumps selector coastal, because it can't be
2244 reliably computed from other xdump information.
2245 - New xdump realm and country. Realm information is now stored in
2246 a separate file, with appropriate selectors.
2247 - Reviewed for completeness and information leaks. See info xdump
2248 for remaining issues. New treaty selector uid, nat selectors
2249 relations, contacts. Removed useless selectors: news and lost
2251 - Command syntax changed.
2252 - xdump opt is no more, option information is now in xdump ver.
2253 - xdump can now dump meta-data.
2254 - Header and footer changed to be more compact. You now need
2255 meta-data to identify fields.
2257 - Documentation in doc/xdump.
2258 * New econfig key builtindir.
2259 * New econfig key custom_tables lets you customize configuration
2260 tables without recompiling. Customizing tables other than unit
2261 tables is not recommended for now. See doc/econfig for
2263 * Check configuration and game state are sane on server startup.
2264 * Remove option NONUKES and NEUTRON. Deities can load a suitable
2265 nuke table to get the same effect.
2266 * Remove option DRNUKE. Use econfig key drnuke_const to control
2267 whether nukes need research.
2268 * Disqualify land units from performing missions while loaded on
2270 * Fix dump for strings without terminating zero.
2271 * Fix login command option not to send an extra prompt.
2272 * zdone now displays information about demand update vetoing.
2273 * The Windows port now requires Winsock version 2.
2274 * Remove econfig key powe_cost.
2275 * version report now shows all the configurable settings of interest
2277 * carg and lcarg now display people as well.
2278 * ldump now dumps civ and uw as well.
2279 * Fix dangling pointer dereference in dogfighting code.
2280 * Tell sector owner when partisans take over. But don't disclose che
2282 * emp_server, files, fairland now support options -h and -v.
2283 * Simplify baroque version numbering to a single version number.
2284 This affects output of version.
2285 * New show item and show news.
2286 * New build process:
2287 - Follow the usual steps: configure; make; make install. The
2288 latter is optional. The only file deities still have to edit is
2290 - Use GNU Autoconf for system configuration.
2291 - Use GNU Make for portability and features.
2292 - Support separate build trees.
2293 - Remake out-of-date dependencies automatically.
2294 - Remake out-of-date info files automatically.
2295 - Flatten info directory.
2296 - Formatted info files are no longer distributed in source tarball.
2297 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
2298 low-level options doesn't seem to be worth the effort, as
2299 UCONTEXT should be pretty portable.
2300 * Fix use of freed memory in sail.
2301 * sail could let large ships enter big cities.
2302 * Fix reject and accept not to require contact.
2303 * Fix sharebmap and telegram to prompt for a missing first argument.
2304 * Fix report to align column research correctly for deities.
2305 * When the optional newspaper argument doesn't work because HIDDEN is
2306 enabled, complain instead of ignoring it silently.
2307 * When BLITZ is enabled, fairland no longer permutes country numbers
2308 in newcap_script so that start islands are ordered from top left to
2310 * Minimize output format differences between options:
2311 - census shows column fall regardless of FALLOUT.
2312 - show nuke now shows column res regardless of DRNUKE.
2313 - report no longer suppress column status when HIDDEN is enabled.
2314 HIDDEN limits status information like for the country command.
2315 - relations column width differed depending on option SLOW_WAR.
2316 Always use the wider format.
2317 * Fix a bug in edit that suppressed the player notification telex on
2318 military reserve change.
2319 * Fix command dispatch not to let deities use commands that are
2320 declared not to be available to them. The only command affected is
2322 * Fix the list command for visitor.
2323 * econfig key m_m_p_d no longer applies to deities.
2324 * Fix the origin command for country #0. Allow moving origin to
2325 another country's origin. Allow deities to reset origin to
2326 absolute 0,0. This turns origin into a superset of the offset
2327 command. Remove offset command.
2328 * Fix a bug that caused unpredictable flak damage when it should have
2329 been maximum damage (was broken in 4.2.19).
2330 * Don't store initial capital location, remove the associated nat
2331 selectors xstart, ystart.
2332 * Fix production command to consider resource depletion.
2333 * Fix justification of coordinate output in cutoff and mission.
2334 * Option UPDATESCHED is no longer optional. Disabling it didn't
2337 * Turn options into ordinary econfig keys.
2338 * New econfig key start_cash.
2339 * BTU regeneration now depends on the capital's work percentage.
2340 * nation now supports an optional argument that lets deities ask for
2341 somebody else's nation report.
2342 * Fix nation to display SANCTUARY instead of VISITOR for countries in
2344 * Fix capital to let you use a regained sacked capital without
2345 activating another one in between.
2346 * Don't move capital when it is sacked.
2347 * New ship capability canal, replacing obscure formula based on build
2349 * You now need a capital to request a demand update.
2350 * power now ignores landspies.
2351 * Fix LWP stack checking.
2352 * Clean up LWP, drop dead machine-specific code, fix portability bugs
2354 * census now shows the old owner instead of `*'. dump is unchanged
2355 to avoid breaking clients.
2356 * peek no longer prints the old owner.
2357 * When a bombed land unit retreated, collateral damage was applied to
2359 * paradrop, drop and fly can no longer abandon the base sector.
2360 * Tending foreign ships now sends a bulletin to the owner.
2361 * Fix bug that permitted login for inactive countries, including ""
2362 * Fix tend for spies.
2363 * Change launch to fire all missiles selected at the same target.
2364 Previously, it prompted for a new target after each missile.
2365 * add, consider, build, launch and fire no longer re-prompt when
2366 supplied with a bad argument, they just fail. Consequently, the
2367 build command no longer lets you list types you can build. It
2368 points to the show command instead.
2369 * Fix add not to truncate country number.
2370 * Fix selector coastal to be accurate at all times.
2371 * Fix obscure bug in fairland: the sector added last to an island
2372 wasn't considered coastal. Affected resource computation.
2373 * Fix sector wiping in add command.
2374 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
2375 ways. Custom configuration tables should become a serviceable
2376 replacement eventually.
2377 * Client no longer freezes on long lines of server output.
2378 * Fix uninitialized signal mask bugs.
2379 * Fix Windows service code's treatment of -e.
2380 * Sub interdiction disclosed sub owner through news' actor selector.
2381 * country reports on all countries, but carefully limits information
2382 disclosed to mortals. Output format changed.
2383 * Market no longer forces sellers to grant loans.
2384 * Fix potential crash bug in set command. Friendlier prompt and
2386 * Substantial code cleanup and portability fixes.
2387 * Extend empfile abstraction to cover game configuration.
2388 * Overhaul of game state storage.
2389 * The above includes major contributions from Ron Koenderink. Many
2392 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
2393 * Make version pretend option SHIPNAMES still exists, for the benefit
2394 of clients that still depend on it.
2395 * The change to conv in 4.2.22 could crash or compute incorrect
2397 * Info updates missing in 4.2.22.
2398 * A few code cleanups.
2400 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
2401 * Log player login, logout and session kill.
2402 * Close loophole in assembly point rules that allowed players to find
2403 all unowned sectors. The assembly point must now be owned by you
2404 or an ally, or you or an ally must have a ship there.
2405 * Don't let embarked land units fire flak.
2406 * Fix display of the last connection's host when the host name was
2408 * Fix change command to accept full length representative (password),
2409 currently 19 characters. It used to chop off after eight
2411 * Non-recon missions no longer establish contact to owners of
2412 overflown sectors, because those missions do not identify the
2413 owner. This matches info Hidden.
2414 * The following events now establish contact:
2416 - Sighting a ship when toggle coastwatch is off
2417 - Spotting overflying planes
2418 - satellite spotting land units
2419 - lookout and llookout spotting ships, planes and land units
2420 - Any relations change
2421 * The country command's `temporary' state of disorder ended after
2423 * Telegram notifications could get lost in exotic circumstances,
2424 e.g. while a second client attempted to connect. Can be abused for
2426 * Remove option SNEAK_ATTACK.
2427 * Fix lboard not to let you board dead land units.
2428 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
2430 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
2432 * Fix fly to let the player abort the command at the last prompt.
2433 * Client no longer reads execute scripts in binary mode under
2435 * New econfig key listen_address.
2436 * econfig key port can now be a service name. Service empire no
2437 longer takes precedence over econfig.
2438 * Client falls back to compiled-in host only if environment doesn't
2439 supply one, not if it can't be resolved. Same for port.
2440 * Oil derrick could extract slightly more oil than was in the ground.
2441 * test command checked start sector for space and some other things
2442 instead of end sector.
2443 * convert now silently limits conversions to avoid exceeding maximum
2445 * shoot no longer limits you to 999 victims.
2446 * 4.2.19 broke pin-bombing commodities on some platforms.
2447 * Don't block on output while update is pending. This is required to
2448 ensure the update can abort commands.
2449 * Commands submitted while the update is waiting for commands to
2451 * The force command no longer waits for the specified time. It
2452 starts a scheduling thread instead, just like shutdown.
2453 * Correct grammar and punctuation in output of version.
2454 * Option SHIPNAMES is no longer optional.
2455 * Fix output of qorder and sorder for ships with sail path.
2456 * Don't change capital to agribusiness on retake. From Pat Loney.
2457 * bdes prompt for new designation was messed up for empty bmaps.
2458 * Client now supports pipes under Windows.
2459 * Care for subtle Windows socket incompatibilities.
2460 * Fix strength command not to lie about units reacting into
2462 * strength now yields the processor periodically, to keep the game
2464 * Schedule commands more fairly. Previously, a sufficiently fast
2465 player could starve out the others.
2466 * launch assumed plane maximum mobility 127 for calculating when
2467 satellites will be ready to use.
2468 * Drop support for for DCE threads.
2469 * Drop support for pthread implementations lacking pthread_kill().
2470 This includes ancient versions of OS X.
2472 * Minor info file fixes.
2473 * The above includes major contributions from Ron Koenderink. Many
2476 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
2477 * Don't let threads block on output to another player thread's
2478 socket. Such blocking violates basic design assumptions and can
2479 cause all kinds of grief. In particular, it causes player session
2480 hangs under Windows with 4.2.20. Broken since the introduction of
2481 flash and asynchronous telegram notification many years ago.
2482 * Threads sleeping until a specified time could return early under
2483 Windows. This could cause double-updates.
2484 * Fix fallout damage (was broken in 4.2.19).
2485 * Fix show sector s (was broken in 4.2.19).
2486 * Fix deliver not to deliver friendly civilians into occupied
2488 * Fix mil duplication in board (was broken in 4.2.14).
2489 * Fix stack smash in lrange, shoot and execute. Remote holes, and
2490 the last one doesn't even require authentication.
2491 * Fix crash bug in emp_config parsing.
2492 * Fix buffer overruns in turn and shutdown.
2493 * Fix second argument of shutdown.
2494 * announce, pray, telegram and turn now abort on EOF.
2495 * Fix display of MOTD and game down message of maximum size.
2496 * Correctly support telnet line termination on input. Previously,
2497 carriage returns could slip into ship names and such.
2498 * Fix flash not to lie about recipients that are just logging in.
2499 * Remove obscure login command list.
2500 * Convert client from obsolete termcap to terminfo, and clean up
2502 * New fairland option -h to print usage information. Improved
2503 command line syntax diagnostics. Exit unsuccessfully on unknown
2505 * fleet and army now copy retreat orders of the fleet's or army's
2506 first member with group retreat orders in the same sector.
2507 Previously, they used the retreat orders of the first fleet or army
2508 member, which is less than useful, and failed to take ownership
2509 into account, which is an abusable bug.
2511 * Fix xdump not to disclose other countries' losses.
2512 * Fix exit status of files program when it can't create files.
2513 * Support UTF-8 encoded Unicode in human-human communications. This
2514 affects MOTD, game down message, telexes, announcements and flash
2515 messages. See new doc/unicode for technical details.
2516 * New login command `options' for client/server option negotiation.
2517 See new doc/clients-howto for technical details. The only option
2519 * emp_client -u now requests UTF-8. This requires a terminal that
2521 * Fix news for land unit defensive support.
2522 * Properly mark sea mines hit by retreating ships. Unmark mines
2524 * Fix diagnostics for unknown selector names in conditionals (was
2526 * Fix selector name clashes: rename ship selector mobquota to mquota,
2527 land selector for reaction range limit from rad to rmax.
2528 * Fix Windows services for relative file names on command line or in
2529 econfig (was broken in 4.2.20).
2530 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
2531 are now float. This gives deities finer control over maximum
2533 * Fix production command for sectors with 60% efficiency.
2534 * Improve syntax of read for deities.
2536 * Some info topic names differed only in case, which loses on
2537 case-insensitive file systems, and is a bad user interface even
2538 when it works. Change those names. Rename deity command hidden to
2539 peek because its info topic clashed with that of option HIDDEN.
2540 * Thanks to Doug Wescott sheep are finally covered properly in info.
2541 * Documentation fixes.
2542 * Much of the above was contributed by Ron Koenderink. Many thanks!
2544 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
2545 * When units in different sectors marched, only units in the sector
2546 with the highest-numbered unit were interdicted. A marching
2547 non-spy made all marching spies visible to interdiction regardless
2549 * Fix crash when interdiction sinks second ship in a sector. Broken
2551 * Fix an ancient bug in simulation of level production that clobbered
2552 stack and could lead to low predictions, typically zero, which
2553 screwed up budget. The bug had no effect until 4.2.19.
2554 * When a sector revolts, and there wasn't enough space to liberate
2555 all uw, the number of remaining uw got the wrong sign. Broken in
2557 * Log and abort when LWP stack check detects stack smash. Server
2558 option -s no longer implies -p.
2559 * The native Windows build now supports -p and -s.
2560 * The native Windows build now properly deals with ^C when running in
2561 the foreground. It no longer prompts for a quit command on the
2563 * The meaning of server option -D in presence of -e is unclear.
2564 Other programs only support -e. Remove option -D. Use -e
2565 DIR/econfig instead of -D DIR.
2566 * New server option -v shows version information.
2567 * Fix the server's exit status with -h. Broken in 4.2.19.
2568 * The linux-pthreads build failed to shut down on signals.
2569 * Fix threading bugs in the native Windows build that made shutdown
2570 unsafe and screwed up update aborting commands.
2571 * New econfig key pre_update_hook to allow automatic, safe backup
2572 right before the update. See scripts/backup for an example.
2573 * The server now prints log messages to stderr as well when running
2575 * Fix potential buffer overflows in logerror() and lwpStatus().
2576 * Server now requires POSIX signals. It no longer catches SIGUSR1.
2577 * Remove support for ancient versions of HP-UX.
2578 * Fix seeding of PRNG broken in 4.2.19.
2579 * Don't reseed the PRNG in commands, it hurts randomness and could be
2580 abused by crafty players.
2581 * The server now makes the data directory its working directory.
2582 This also gets rid of a bug that changed the file name of the
2583 sector, power, nation and lostitems file unless econfig could not
2585 * The server now writes a pid file. Thanks to Daniel O'Connor.
2586 * More user friendly server startup: more errors are detected while
2587 the server still runs in the foreground, which makes it possible to
2588 complain to stderr and to exit unsuccessfully.
2589 * Early log messages went to the log file in the default data
2590 directory, even though econfig specifies another data directory.
2591 * Specifying an econfig file on the command line that can't be read
2593 * Errors in econfig are now fatal.
2594 * The server now refuses to start when it can't open data files.
2595 * News are now sorted and expire sanely.
2596 * Conditionals can now compare strings as well.
2597 * Corrupted down and motd files could cause buffer overflows.
2598 * Fix recon to let player abort at the flight path prompt.
2599 * power no longer rounds worldwide numbers for deities.
2600 * power command failed to recognize deities with non-zero country
2602 * Change output of production command so that columns are aligned
2603 even for large values. Replace column wkfc by more useful column
2605 * neweff and production miscalculated work when mil exceeded
2607 * neweff miscalculated work when the population limit exceeded 999.
2608 * Fix capping of avail when a big city is torn down.
2609 * Fix a bug in fire that allowed players to find all submarine uids.
2610 * Maximum sector population is no longer hardcoded, and now covered
2611 by xdump. Option RES_POP now affects mountains and plains as
2612 well. From Ray Hyatt.
2613 * Fix fina and news not to ignore errors in conditions.
2614 * The native Windows build now requires Windows Sockets 2.
2615 * The native Windows build now supports multiple instances of the
2616 service. The ability to supply additional startup parameters to
2617 the service has been removed.
2618 * Implement fairland command line parsing under Windows.
2619 * Improved fairland and emp_server usage message.
2621 * Minor info file and documentation fixes.
2622 * Much of the above was contributed by Ron Koenderink. Many thanks!
2624 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
2625 * Fix order not to unload into full sectors.
2626 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
2628 * Fix distribute not to conjure up a civilian when importing
2629 civilians from a dist center that doesn't have any.
2630 * Fix flak to resupply no more shells than actually needed.
2631 * Fix rounding error in shoot that could result in more people shot
2632 than actually there.
2633 * Fix info and apro error handling. In particular, do not leak
2634 potentially sensitive information on the server to players.
2635 * info no longer shows a random matching page when the topic argument
2636 is ambiguous. Instead, it lists all matching topics.
2637 * Embarked land units and overflying planes no longer spot each
2639 * Fix show command to show only sectors that players can designate
2640 (was broken in 4.2.18).
2641 * Fix a rounding error in production command column `max'.
2642 * Fix production command for overpopulated mountains and plains.
2643 * Fix tradeship ally cut to match documentation.
2644 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
2645 * Fix a bug in aerial sonar where ships could mask submarines with
2646 the same number modulo 256.
2647 * Don't allow bombing of subs that were not detected.
2648 * MOTD and the game down message are now entirely separate: use `turn
2649 motd' for the MOTD, and `turn on' and `turn off' for the game down
2650 message. `turn on' no longer lets you edit the MOTD.
2651 * Remove option NUKEFAILDETONATE.
2652 * Option ORBIT is no longer optional.
2653 * New option GUINEA_PIGS to control experimental stuff not ready for
2654 prime time. If your deity enables this in a serious game, run!
2655 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
2656 * New ship and land selectors rflags, rpath.
2657 * New ship selectors for order: xstart. xend, ystart, yend,
2658 cargostart, cargend, amtstart, amtend
2659 * New ship selectors for sail: mobquota, path, follow.
2660 * New news selector uid.
2661 * Implement command line parsing under Windows where it was missing.
2662 * emp_server and and files print a usage message on command line
2664 * Fix how emp_server exits after being panicked by a signal. It can
2665 now dump core when this happens.
2666 * Fix bug in client that could crash it when a line of input starts
2668 * Client now gets user name from environment variable LOGNAME if set,
2670 * The native Windows build can now run as a service.
2671 * Redirecting client input now works under Windows.
2673 * Don't confuse work with loyalty in info Citizens.
2674 * Minor info file and manual page fixes.
2675 * Much of the above was contributed by Ron Koenderink and Marc
2676 Olzheim. Many thanks!
2678 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
2679 * Fix info to accept abbreviated arguments under Windows. From Ron
2681 * Buying planes or land units loaded on something didn't work when
2682 that something moved.
2683 * Fix a bug that could produce update cascades with update policy
2685 * Fix delivery and distribution to grant packing bonus only to
2686 efficient sectors, just like move. Previously, delivery ignored
2687 efficiency, and distribution behaved as if it were an efficient
2688 sector without special bonuses.
2689 * New sector selectors loyal, access; ship selectors radius, access,
2690 xbuilt, ybuilt, builder, name; plane selectors radius, access,
2691 theta; land unit selectors radius, react, nland, access; lost
2693 * Fix sector selectors che, che_target; plane selectors att, def;
2694 nuke selector types; treaty selector exp; news selector time;
2695 commodity selectors type, xbuy, ybuy.
2696 * Option PLANENAMES is no longer optional.
2697 * Ensure config parameter variables and their description in
2698 configkeys[] are consistent. Inconsistencies there caused bugs in
2699 the past. From Marc Olzheim.
2700 * Complain if econfig file can't be read.
2701 * Better messages for errors in econfig file.
2702 * Remove unused econfig keys hard_tech and last_demand_update.
2703 * New econfig key news_keep_days to configure news expiry.
2704 * New econfig key anno_keep_days to configure announcement expiry.
2705 * Fix announcement expiry. It leaked file descriptors and memory,
2706 and could corrupt the anno file. From Ron Koenderink.
2707 * New command xdump: experimental extended dump. Disabled for now.
2708 * Bankers no longer round down debts, and they collect interest for
2709 the time debtors are idling at sub-prompts.
2710 * Loan interest calculation was broken at the due date and after a
2711 last payment made at the due date. With luck, debtors could abuse
2712 this to repay loans cheap (they couldn't gain cash, though), sharks
2713 to purchase loans cheap, and creditors to collect excessively.
2714 * Fix major bug in transport that allowed two cooperating countries
2716 * Don't report interdiction damage twice when transporting planes.
2717 * Fix message for attempting to transport a plane in a sector not
2718 owned by the player.
2719 * Fix confusing diagnostics when refusing to improve defense because
2720 option DEFENSE_INFRA is off.
2721 * Simplify confusing code in budget.
2722 * Fix spacing in output of budget and show.
2723 * Change one-way plane sorties to match ordinary sorties: offer
2724 carriers regardless of the sector they're in, require carriers to
2727 * Don't print owner of incoming missile twice when intercepting it.
2728 * Simplify constituent storage in product characteristics.
2729 * Replace remaining `variables' leftovers; mainly in unit
2731 * Remove leading spaces in deity unit dumps.
2732 * Replace inappropriate uses of compile time constant ETUS by 60.
2733 Deities don't change ETUS, they change etu_per_update by editing
2734 econfig. This nonsense dates back at least to chainsaw 3.31.
2735 * Change ship production (fishing and drilling for oil) to match
2736 sector production. Ship efficiency and tech are now relevant, and
2737 all people on board work. From Ron Koenderink.
2739 * Minor info file fixes.
2741 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
2742 * Fix seeding of PRNG under Windows. The bug made updates occur at
2743 a predictable time in the update window. From Ron Koenderink.
2744 * Close major loophole in drop that allowed players to determine
2745 whether an arbitrary sector is sea, allied land, or other land.
2746 * fly could fly civilians into occupied sectors. For consistency
2747 with other means to move around stuff, this is no longer possible.
2748 * Don't allow flying to a carrier that doesn't have space for the
2749 planes. Previously, planes that did this were teleported home,
2750 which could be abused.
2751 * Close loophole in bomb that allowed players to find all
2753 * Fix move and explore not to crash when moving civilians to a sector
2754 without civilians, and interdiction destroys them all. Found and
2755 debugged by Jeff Cotter.
2756 * Fix printing of messages entered with turn command. '%' characters
2757 could cause havoc, even crashes.
2758 * Use sector's actual maximum population to compute chance of plague
2759 outbreak. Previously, code used 9999 for big cities and 999 for
2760 other sectors, and info Plague said 999. This makes all crowded
2761 sectors equally vulnerable, even mountains, plains, and inefficient
2763 * Oil derricks no longer drill and deplete more oil than they can
2764 hold. From Ron Koenderink.
2765 * Version 4.2.15's coordinate and list parsing fixes reject trailing
2766 junk. That's too strict. Silently ignore trailing junk as long as
2767 it starts with whitespace.
2768 * Version 4.2.15's selector rewrite broke some type literals,
2769 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
2770 type literals to selectors.
2771 * Nightly build patches game to get repeatable PRNG results. From
2774 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
2775 * Previous version broke sector production when part of the work is
2776 used for sector construction. Fix courtesy Jeff Cotter.
2777 * Add rudimentary tests to nightly build. From Marc Olzheim.
2779 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
2780 * test command no longer asks whether to abandon the sector.
2781 * explore command could generate a bogus `lost' record when it
2782 regains an abandoned start sector.
2783 * edit command now properly updates stats when editing tech level of
2784 ships, planes or land units. A few of these stats can be edited
2785 separately, which doesn't make much sense, and is now deprecated.
2786 * edit command no longer accepts efficiency values that would destroy
2787 the edited unit. Deities can still delete units by setting the
2789 * upgrade command used to charge an amount of avail that didn't match
2790 info upgrade. Neither the implemented nor the documented amount
2791 made much sense. Change it to 15% of the full build cost. Rewrite
2793 * Commands upgrade and build could be off by one when reporting
2795 * upgrade command reported rounded cost but charged unrounded
2796 cost. Round cost of upgrade down to match behavior of build.
2797 * Upgrading planes now preserves range when it is less than the
2798 maximum range. It used to set it to the new maximum range.
2799 * show bridge and show tower no longer claim bridge building requires
2800 `workers' (whatever that is), since it doesn't.
2801 * Replace option ROLLOVER_AVAIL by econfig parameter
2802 rollover_avail_max, which is the maximum amount of avail that rolls
2803 over. Previously, avail was limited after rollover, and even when
2804 ROLLOVER_AVAIL was off. Fix that.
2805 * Ships weren't always charged mobility for firing with option
2807 * Fix shell use of return torpedoes.
2808 * designate no longer complains twice about deity only designations.
2809 * Ensure designate zaps efficiency only when sector type really
2811 * Fix strength to always report mines to deities.
2812 * Remove option SHIP_DECAY.
2813 * Fix bug in sonar that could crash or yield unpredictable results
2814 near the true origin.
2815 * Fix buffer overflow in flash and wall.
2816 * Fix wall not to strip out first word of message.
2817 * Change market and order to use item types instead of mnemo
2818 characters internally.
2819 * Market now reports sales with full item names instead of single
2821 * buy now requires first argument to be an item name, as documented.
2822 * production command handled production backlog incorrectly, failed
2823 to limit production for production efficiency greater than one,
2824 e.g. agribusiness, and incorrectly limited raw material
2825 consumption. Also fix a rounding error. With help from Ron
2827 * Sector work was accidentally truncated to even.
2828 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
2829 don't divide SHRT_MAX+1.
2830 * Properly diagnose over-long unit lists.
2831 * Rewrite selector code. Old code let players smash the stack by
2832 supplying too many conditions. New code properly rejects ambiguous
2833 abbreviations and prefers exact matches. Selectors with names that
2834 collide with types, like land units' rad and spy, now work.
2835 Selectors with non-integral values, like land units' att, now work.
2836 * survey used to display hundreds for everything but variables. Now
2837 it displays hundreds only for values that can be large.
2838 * Rewrite info survey. Document ability to survey properties other
2839 than items and resources.
2840 * Rewrite info build, since it was inaccurate and poorly structured.
2841 * Fix info fire on required military. From Marc Olzheim.
2842 * New fairland argument -R to set the PRNG seed. Print the seed.
2843 This allows you to recreate the same world again.
2844 * New facilities to deal with internal errors. These crash when the
2845 server is started with -d, which is appropriate for debugging, and
2846 potentially disastrous for running a real game.
2847 * Automated nightly builds.
2850 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
2851 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
2852 * Gripe about unknown options in econfig.
2853 * Remove option GRAB_THINGS.
2854 * Utility program files takes new option -f.
2855 * Remove utility programs land, ore and perfect, which don't compile
2856 since 4.2.0 (Oct '98).
2857 * fairland no longer warns when it added resources, but when it
2859 * Fallout code could claim destruction of more items than actually
2861 * Fix recursive resupply (resupply from supply land unit triggering a
2862 resupply of the land unit) when just testing for how much can be
2863 resupplied. The bug could have led to insufficient resupply.
2864 * Fix recursive resupply not to consume all fuel in supply units. No
2865 supply units consuming fuel exist in the stock game.
2866 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
2867 Distribution threshold were previously limited to 10000, and
2868 delivery thresholds to 65528.
2869 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
2870 used to limit to 9990. Market transactions and commands explore,
2871 move, drop and fly to 32767. Limiting in autonav code (order
2872 command) didn't work. Item delivery used to stop at 9990,
2873 distribution at 9999. Food growing and sector production used to
2874 stop at 9999. Grind, assault lunchboxes, demobilization, mine
2875 sweeping and che liberating uw could theoretically attempt to
2876 increase items beyond 65535, which would have been ignored
2877 (destroying the increase).
2878 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
2879 fallout increases behaved inconsistently. Increases beyond 65535
2880 could get ignored, or fallout could saturate at 9999, or it could
2881 overflow at 65536 (that would take quite some nuking, though).
2882 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
2883 operation that would have gone beyond 65535 was ignored.
2884 * Fix `are we loading or unloading' tests for load, unload, lload and
2886 * Fix editing of land unit attack and defense values. Implement
2887 editing of ship defense values. Contributed by Ron Koenderink.
2888 * edit now edits che number and target separately.
2889 * Fix edit to properly extend unit files. Contributed by Ron
2891 * Major internal reorganisation: Sectors need space for items,
2892 deliveries and distribution thresholds. To save space, the
2893 ancients invented `variables': a collection of key-value pairs,
2894 missing means zero value, space for `enough' keys. This
2895 complicates the code, as assigning to a `variable' can fail for
2896 lack of space. Over time, `enough' increased, and for quite some
2897 time now `variables' have been *wasting* space. Replace them,
2898 except in unit characteristics, where they are read-only, and will
2899 be replaced later. This also removes misfeatures like plague
2900 outbreaks silently deleting deliveries.
2901 * Remove disabled commands dissolve and mult. Remove configuration
2902 parameters minmult and maxmult.

2913 wasteland and wilderness.
2914 * map commands now display wilderness and plains owned by other
2915 players as '?'. Radar commands now display all wilderness and
2917 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
2918 * Make client abort the current command on ^C under Windows, as
2919 everywhere else. Contributed by Ron Koenderink.
2920 * Command line parser interpreted trailing whitespace as an another
2921 (empty) argument. Ignore it instead.
2922 * Properly declare stuff in headers, include proper system headers.
2923 Remove all nested external declarations. Source code is now fully

2932 * Move some code to more logical places. Remove some unused code,
2933 some of which was hard to port.
2934 * The files program could print error messages to a log file in some

2979 * Fixed non-portable fd_set * arguments of select().
2980 * New `map' flag `h' to highlight own sectors. Contributed by Marc

2983 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
2984 * Fix Windows server shutdown on reading "quit" from stdin.
2985 * Land units now fortify automatically when mobility plus growth

3013 * Don't sleep in main thread when called from signal handler.
3014 * Fixed error checking in pthreads.

3107 * Added new NF_SACKED flag to indicate when a country has had it's
3108 capital sacked. This flag is only cleared when the country actively
3109 redesignates it's capital using the "capital" command, and changed
3110 capital.t to reflect this (no more re-sacking after an update if the
3111 country doesn't reset and repeating until they are out of cash.)
3112 * Added land unit to edit command for planes.
3113 * Added nuketype to edit command for planes.
3114 * Changed so that if the leader of a group of units is a train, the
3115 railways are used for bestpath instead of roadways.
3116 * Changed mission command to also print reaction radius of reserve
3117 missions when set for land units.
3118 * Changed Flak.t to reflect guns having to be loaded onto a land unit

3125 the sector, ship or unit a plane is taking off from if it is not owned
3126 by the owner of the plane.
3127 * Changed so that when a sector reverts during a guerrilla revolt, the
3128 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
3129 you would always get at least an updates worth of mobility. With
3130 MOB_ACCESS, sectors that reverted during the update were useless, since you
3131 got no mobility for a long time. This fixes that problem, and makes che
3132 more useful as well.
3133 * Changed so that air defense missions don't always send up every plane in the
3134 area, but instead always send up at most two times the number of incoming
3135 planes (for each interdicting country.) This helps to stop 1 plane from
3136 stripping the mobility from 25 air defense planes all at once, but doesn't
3137 limit it to n+1 as there is for regular interception.
3138 * Clarified deity reversion of sectors in Sector-ownership.t
3139 * Clarified production efficiency and added pointer to "show sector cap"
3141 * Clarified nuketype selector for planes in Selector.t

3145 * Cleaned up comments causing minor complaints in some builds.
3146 * Fixed bug in loans where you could collect on proposed loans.
3147 * Fixed production command to be more accurate (though it *still* has some
3148 rounding errors, it's better.)
3149 * Fixed potential memory leak in air defense missions.
3150 * Fixed bug where you couldn't pinbomb some commodities if other commodities
3151 didn't already exist in the sector.
3152 * Fixed bug where you couldn't build 0 crew planes without military in the
3153 sector. (This is different from needing at least 1 military to build all
3154 planes that need a crew which introduced another related bug earlier.)
3155 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
3156 messages to be displayed for deity owned planes.
3157 * Fixed bug where land units on ships in a sector taken over were blown
3159 * Fixed bug where planes on ships in a sector taken over were blown up
3161 * Fixed bug in sdump printing origx and origy in deity coordinates.
3162 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
3164 * Fixed bug in launch showing wrong satellite target (showed asat instead
3165 of the target satellite.)
3166 * Fixed bug where you could gain information not normally available using
3167 the "fire" command to determine sector type information.
3168 * Fixed bug in market/trade creating extra money when loans are taken out.
3169 * Fixed problem with land units not being reported sunk after being sunk
3170 on a ship that was nuked or wastelanded in a sector.
3171 * Fixed problem with Spies.t using "llook" instead of "llookout".
3172 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
3173 on some Linux boxes.
3174 * Fixed problem with plague infection being way too high in cities when
3175 the BIG_CITY option is enabled.
3176 * Fixed bug in edit command getting confused with arguments.
3177 * Fixed bug in ask_move_in_off asking you to move in a negative number of
3178 troops (hey, it could happen. :) )
3179 * Fixed bug in add command not keeping flags or relations initially correct.
3180 * Fixed bug in torpedo command sometimes telling victim about torpedo
3181 sightings even when way out of range.
3182 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
3183 as not formatting them properly when reporting them.
3184 * Fixed bug in satellite with noisy transmission causing a potential
3185 crash of the server with non-100% efficient satellites.
3186 * Fixed potential crashing of the server during satellite display when not
3187 calculating distances to ships and units correctly.
3188 * Fixed bug where planes in non-allied sectors, ships and units could be
3190 * Fixed bug where planes on the trading block could be used on missions.
3191 * Fixed bug where planes and units that get traded don't have mobility set
3192 correctly when using MOB_ACCESS option.
3193 * Fixed bug which made security units virtually useless.
3194 * Fixed access times and mobility not being set right when building planes,
3195 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
3196 * Fixed minor formatting problem with launch of satellites.
3197 * Fixed minor formatting problem with planes with greater than 999 tech.
3198 * Fixed minor formatting problem with ships with greater than 999 tech.
3199 * Fixed problem with "llook" showing up in TOP info file.
3200 * Fixed problem with lwp Makefile choking on NT builds with clean target.
3201 * General cleanup of potentially ambiguous statements.
3203 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
3204 * Added "TECH_POP" as an option where technology costs more to make
3205 as your population grows past 50K civilians. It is disabled by
3207 * Changed "produce" command to accurately print what the true p.e. is.
3208 * Changed "update" command to display if mobility updating is enabled for
3210 * Fixed bug where toggling off the coastwatch flag also turned off
3211 forts firing on hostile ships coming into range.
3212 * Fixed bug where assaulting your own land would violate any treaties
3213 you have where assaults are a violation.
3214 * Fixed bug where all planes (even those without need for a crew, such
3215 as missiles) needed at least 1 military to build.
3216 * Fixed bug where when a ship sinks during the update due to lack of maint,
3217 land units and planes on it were left stranded.
3218 * Fixed bug where when a land unit dies during the update due to lack of
3219 maint, land units and planes on it were left stranded on it.
3220 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
3222 * Fixed bug in "show sector capabilities" not showing products correctly.
3223 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
3225 * Fixed bug in sectors that don't revolt not showing up as lost items.

3229 * Fixed bug in the way treaties are examined and sometimes produce
3231 * Fixed edit to allow creating negative mobility for sectors.
3232 * Fixed setsector to allow creating negative mobility for sectors.
3233 * Fixed bug where when writing out the value of a sector that had
3234 negative mobility and was damaged in combat, mobility was being
3236 * Fixed Taxes.t info page to reflect that captured civvies only pay
3238 * Fixed Technology.t info page to reflect TECH_POP option.
3239 * Fixed navigate.t info page to reflect that only ships in the fleet
3240 in the same sector that are fired upon have damage divided up.
3241 * Made techlists toggle on by default (so things are shown in order of
3242 technological advances.)
3244 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
3245 * Added optimization to increasing mobility to check if an object is
3246 already at max mob, just return since it can't be increased.
3247 * Added "-ltermcap" for client libs for hp build (it was already in
3249 * Added clearing of telegram flags after the update so that the next
3250 telegram is flagged as new and not part of the update.
3251 * Fixed Update-sequence.t to reflect MOB_ACCESS.
3252 * Fixed bug where fortification amount was not being limited to
3253 maximum mobility for land units (land_mob_max).

3255 by using 127 instead of land_mob_max.
3256 * Fixed bug where scrapping land units was creating military.
3257 * Fixed description of sect_mob_neg_factor in econfig file.

3269 value when MOB_ACCESS was enabled.
3270 * Fixed bug in enlist setting mobility incorrectly sometimes.
3271 * Added doc/backup file for deities which recommends how backups and
3272 restores of the data directory should be done.
3274 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999

3280 * Changed fairland to allow 0 sector distance to other islands and
3281 continents (James Risner)
3282 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
3283 match the way ships are described (since this is how they really work.)
3284 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
3285 and "fir" as the number of guns that a land unit fires.
3286 * Cleaned up misc. build warnings.
3287 * Changed artillery damage to be 5 + d6 per gun firing from just d6
3288 per gun firing and updated Damage.t to reflect this change.
3289 * Changed artillery firing ranges to be like ships ranges - divided
3290 by two, and modified them to make more sense.
3291 * Changed artillery units to be "slightly" :) more powerful.
3292 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
3293 * Changed "artillery" unit to tech 35.
3294 * Changed so that guns are no longer required to build units, and
3295 that guns must be loaded onto artillery units for them to fire.
3296 Client developers note: the show command has not changed yet to
3297 remove the 'guns' column (since guns are no longer required) but
3298 will in a future revision (possibly 4.2.4) so "be prepared" for
3299 "show land build" to change. :)
3300 * Fixed landunitgun to handle all the damage calculations like it should.
3301 * Fixed bug sinking planes when the ship they are on sinks.

3321 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
3322 on a machine to work out the bugs. (Note that the only build that
3323 works on Linux/Alpha is the linux-pthreads)
3325 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
3326 * Added some code optimizations into the update code when building paths.
3327 * Added some new cacheing for building paths to help speed up updates.
3328 * Added so that you can use "name" and "password" with the change command
3329 as well as "country" and "representative".
3330 * Added flag to power command so that if you are a deity and enter
3331 a negative number of countries you want to see, you see the power chart
3332 for that many countries without power numbers on the next line. Only
3333 useful for deities that want to see the chart un-broken up by that line.
3334 * Added new functionality to fortify command. You can now use a negative
3335 fortification value to cause the unit to be fortified and leave at
3336 least that much mobility on the unit. I.E. "fort * -67" will fortify
3337 all units and make sure the mobility of each unit doesn't go below
3338 67. If the mobility is already below that level (or equal) the unit
3340 * Added that the realm command prints "Realm #n is x:x,y:y" after
3341 you set a new realm.
3342 * Added TREATIES option and enabled it by default.
3343 * Added "no depth-charging subs" and "no new land units" treaty
3345 * Added Trannie Carter's basic client fix to use fgets instead of gets.
3346 * Changed market and command to only print the lowest priced lot of
3347 each given commodity by default. If you specify "all" it shows
3348 all lots on the market, and if you specify a specific item, it shows
3349 all lots of that item type.
3350 * Changed start command to only write out sector if it changed.
3351 * Changed stop command to only write out sector if it changed.
3352 * Changed how plane names were changed on server startup if the
3353 PLANENAMES option was enabled.
3354 * Changed move command to use standard askyn function for abandoning
3356 * Changed plane overlight sightings to take stealth into account,
3357 and if the planes managed to evade all flak and interceptors, they
3358 are not marked as "spotted" over enemy sectors.
3359 * Changed all units with the supply flag to have their marching speeds
3360 based on efficiency since that is their purpose. What this means is
3361 that supply units and trains are more effective at 100% than at 10%
3362 (just as fighting units are more effective at 100% than at 10%, but
3363 their effectiveness is determined by how well they fight, not how well
3364 they "run away, run away!" :) )
3365 * Changed so that flash toggle is on by default for POGO at setup
3367 * Changed so that when a sector is taken, all land units owned by the
3368 current owner are treated as planes are during takeovers (i.e. there
3369 is a pretty good chance they are blown up, and if not, they change owner
3370 to the attacker and are beat up pretty good.)
3371 * Fixed treaties to work again.
3372 * Fixed bug in taking over land units not using correct pointer (can
3373 cause a crash or data corruption.)
3374 * Fixed collect command to wipe deliver and distribution information
3376 * Fixed potential bug in bmap not working when destination bmap has
3378 * Fixed bug in shark command not getting right nation structure.
3379 * Fixed bug in server where empty commands (for example, all spaces
3380 or tabs) were being reported as bogus commands. They are now just
3382 * Fixed bug in scrap not dropping land units off of scrapped units carrying
3384 * Fixed bug in news where boarding of land units was reported backwards.
3385 * Fixed bug in calculating new people when growing them during an update.
3386 * Fixed missing -ltermcap in HP/UX build.
3387 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
3388 later and being reset to 0 anyway)
3389 * Fixed Sector-types.t to show a '\e' instead of a '/' for wasteland,
3390 since that is what it really is.
3391 * Fixed retreat.t documentation to reflect the "retreat upon failed
3393 * Fixed bug where satellites were not orbiting the world during the
3395 * Fixed bug in torpedos being too smart. They knew how to jump over
3396 land! :) Now the "line_of_sight" routine is used to determine if a
3397 torpedo has a straight path to the destination. If it doesn't, the
3398 torpedo no longer jumps over land, but instead slams into it. This was
3399 an interesting bug because you could torp ships on the other side of
3400 a very skinny island as long as they were in range, even if there was
3401 no sea route possible.
3402 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
3403 units for example) but you still have to pick something to bomb. For
3404 ships it worked ok (just aborted that it couldn't find any more ships)
3405 and this was fixed for land units and planes.
3406 * Fixed server crashing bug when flying a plane and not carrying
3408 * Fixed bug in move losing commodities when it runs out of room in the
3409 destination sector. Goods are now attempted to be returned to the
3410 start sector, and apporpriate steps taken if the start sector is no
3412 * Fixed march to prompt you before you abandon a sector you own by
3413 marching out the last land unit.
3414 * Fixed check functions to only check the relevant portions of the structure
3415 and not the timestamp info that doesn't affect how the object functions.
3416 * Fixed bug in spy command that always told you if a spy unit was in a
3418 * Fixed bug in displaying of land unit missions not showing correct land
3420 * Fixed bug in wire command where new announcements that you read at
3421 the last second don't get wiped out properly.
3422 * Fixed bug where announcement file could be corrupted by very long lines.
3423 * Fixed bug where bmap was not set when player was told what kind of
3424 sector they were attacking (this was an old abusable bug that was
3425 removed long ago to fix the abuse, and it's been fixed in a non-abusable
3427 * Fixed bug where change command would warn you about monetary and
3428 BTU costs, but not prompt you to break out if you didn't want to really
3429 change your country name.
3430 * Fixed bug in sub-launched nukes that are intercepted being reported in
3431 the news incorrectly.
3432 * Fixed bug in load where you could abandon a sector and not know it by
3433 loading your last civilians or military onto a ship.
3434 * Fixed potential memory leak in autonav code.
3435 * Fixed potential bug where you could possibly determine if a sector is
3436 owned or not using one way plane missions.
3437 * Fixed Damage.t info page to properly show damages for planes and
3439 * Fixed deliver.t to include syntax for command.
3440 * Fixed country.t to include syntax for command.
3441 * Fixed bug where ships on orders were not adding radar information to
3442 the bmap during an update.
3443 * Fixed bug where ships on sail were not adding radar information to
3444 the bmap during an update.
3445 * Fixed bestownedpath code to use the bmap properly. Note this is a very
3446 important bug fix. When navigating a ship, players are no longer given
3447 free information that they would not normally know. For example, if you
3448 try sailing your ship off into uncharted areas of your bmap, the bestpath
3449 code will only use as much information as you have on-hand (i.e. your
3450 bmap) to plan out your path for you. If you have no information on an
3451 area, it just keeps forging on, until bumping into something. Of course,
3452 after the initial exploration through an area, the bmap will be set and
3453 used for all future sailings through that area. Harbors and bridges
3454 are still checked for construction worthiness if you know where they
3455 are (i.e. they are on your bmap.) (Overall, what happened before
3456 was that the bestpath code would route your ship around islands that
3457 you didn't even know were there, and you could use various commands
3458 to see how that ship was going to sail during the update and thus you
3459 gained information that you wouldn't normally know.)
3460 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
3461 and "BestAirPath" to use it properly. It is also good to note that
3462 bestownedpath is used to determine paths for ships and for planes,
3463 and that best_path (which uses the A* algorithm) is used for all land
3464 based paths, and that the two are never interchanged.
3465 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
3466 and RECON was never used before.)
3467 * Removed extraneous "resnoise" and "resbenefit" functions and combined
3468 the two for setresource and setsector commands.
3470 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
3471 * Fixed problem with global/plane.c not defining last structure element
3472 properly, and thus causing crashes when accessing certain plane
3473 routines. This happened during the move to make the PLANENAMES option
3474 run-time configurable.
3476 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
3477 * Bumped rev to 4.2.0 since this is a major release (the server is now
3478 run-time configurable for just about everything and is released under
3480 * Put in official licensing information.
3481 * Re-arranged and commented the econfig (Empire Configuration) file. The
3482 auto-generated "data/econfig" file is now pumped out chock full of
3483 comments (which may or may not be useful.) Since the server is
3484 pretty much fully run-time configurable (MAXNOC is not, but it gets
3485 a default of 99 anyway) deities will probably be spending more time
3487 * Added server support for building under NT, including mods from
3488 Doug Hay and Steve McClure to get the server building and running
3489 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
3491 * Added Doug Hay's ntthread.c implementation for NT threading.
3492 * Added max pop column to "show sector stats" output.
3493 * Added lboard command for boarding land units from sectors. Only raw
3494 mil can board land units, and only mil and land units aboard the unit
3495 being boarded fight back.
3496 * Added GODNEWS option. When enabled, the deity giving people stuff
3497 is shown in the news.
3498 * Added bridge tower sector ('@')
3499 * Added BRIDGETOWERS option. When enabled you can build bridge towers
3500 from a bridge span. You can then build bridge spans from the tower.
3501 If the tower is destroyed ( <20% eff) bridges connected fall unless
3502 supported on the other side. You can only build bridge towers in open
3503 water not adjacent to land and other towers. Expensive.
3504 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
3505 it is deity creatable only (can't redesignate unless you wasteland it
3507 * Changed "info all" to no longer use printdir, instead it just uses the "all"
3508 info page which contains this information.
3509 * Changed so you can now load up to 2 spy units onto non-land unit carrying
3510 submarines if the LANDSPIES option is enabled. Useful for sneaking up
3511 to shore and spying on your neighbors.
3512 * Changed so spies unloaded from ships are not given as gifts, they are just
3514 * Changed build command to handle building towers ("build t")
3515 * Changed show command to show tower stats ("show t b")
3516 * Changed reject so you can now reject things from any country except
3517 deity countries (this now includes sanctuary countries and visitor
3518 countries you don't want to deal with)
3519 * Changed ndump to dump nuclear stockpile ID as well.
3520 * Changed flash so that if someone allied to you is either not logged on or
3521 not accepting flashes, you are notified. This is info you could gain
3522 otherwise since you can see other countries that are allied to you via
3524 * Fixed bug in news command when HIDDEN mods are enabled.
3525 * Fixed distribute command to only write out to the database if we
3526 actually changed the sector (i.e. if we really moved the dist
3527 center, we write. Otherwise, it makes no point.)
3528 * Fixed threshold command to only write out to the database if
3529 we actually changed the sector (i.e. if we really changed the
3530 threshold, we write. Otherwise, it makes no point.)
3531 * Fixed - population growth and truncation in "Update-sequence.t" info
3533 * Fixed the way fortify takes mobility away from a land unit if
3534 engineers are present.
3535 * Fixed bug in buying commodities at the last minute not resetting the
3536 time correctly in all situations.
3537 * Fixed bug in building nukes where it would always ask if you tried
3538 building more than one at a time.
3539 * Fixed bug where if you put (either by building or by transporting)
3540 more than 127 of one type of nuke in a sector, they all got lost. A
3541 negative wrapover sort of thing.
3542 * Fixed ndump to print # of stockpiles dumped.
3543 * Fixed ndump.t to reflect changes
3544 * Fixed bug in build command that didn't account for EOL characters.
3545 * Fixed bug where you could use planes to drop conquered populace
3546 * Fixed bug in distribute command in how it checked for current distribution
3548 * Fixed pr_flash and pr_inform to no longer send messages if the player
3549 is still in the process of logging in (i.e. not in the PLAYING state)
3550 * Fixed report command output for deities.
3551 * Fixed bug in nuclear damage either taking out submarines when it
3552 shouldn't, or not taking them out when it should.
3553 * Fixed bug in loading units that are carrying units onto other units
3554 (note that it doesn't happen since only HEAVY units can carry other
3555 units and that check works, but that might change some day, and we
3556 don't want units carrying units to be carried by other units, etc. :) )
3557 * Fixed info pages to reflect new sector types.
3558 * Fixed info pages to reflect new spy unit capabilities.
3559 * Fixed show commands to only show trade ships if the TRADESHIPS option
3561 * Fixed build command to only allow building of trade ships if the
3562 TRADESHIPS options is enabled.
3563 * Fixed up some definitions located in many places used for checking
3564 sectors for navigation rights.
3565 * Fixed power.t to correctly describe NEW_POWER formula.
3566 * Made HIDDEN option run time configurable.
3567 * Made LOSE_CONTACT option run time configurable.
3568 * Made ORBIT option run time configurable.
3569 * Made SAIL option run time configurable.
3570 * Made MOB_ACCESS option run time configurable.
3571 * Made FALLOUT option run time configurable.
3572 * Made SLOW_WAR option run time configurable.
3573 * Made SNEAK_ATTACK option run time configurable.
3574 * Made WORLD_X and WORLD_Y run time configurable.
3575 * Made MARKET option run time configurable.
3576 * Made LOANS option run time configurable.
3577 * Made BIG_CITY option run time configurable.
3578 * Made TRADESHIPS option run time configurable.
3579 * Made SHIPNAMES option run time configurable.
3580 * Made DEMANDUPDATE option run time configurable.
3581 * Made UPDATESCHED option run time configurable.
3582 * Made LANDSPIES option run time configurable.
3583 * Made NONUKES option run time configurable.
3584 * Made PLANENAMES option run time configurable.
3585 * Removed SMALL_SERVER stuff (unused baggage)
3586 * Removed trading post sector ('v')
3588 Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
3589 * Fixed bug in aircombat where planes in flight could intercept air
3590 defense planes and take no damage (i.e. they got to fight twice,
3592 * Fixed bug in freeing memory after performing missions that could crash
3593 the server (it mainly happened after an interdiction mission using
3594 planes and escorts, where some escorts came from airports that didn't have
3595 bombers going up. Freeing the leftover escorts was crashing the server.)
3596 * Fixed bug where you could load non-existant units if you were allied
3598 * Fixed bug where you could pin-bomb a plane with itself.
3599 * Fixed bug where satellites over a bridge may get killed if the bridge
3601 * Fixed bug where land units on a ship in the same sector as a bridge
3602 that is splashed may get sunk.
3603 * Fixed bug where planes on a ship in the same sector as a bridge
3604 that is splashed may get sunk.
3605 * Fixed doconfig with correct empire site text.
3606 * Fixed major problem with abms not firing, and sometimes crashing
3608 * Fixed bug in land units counting up loaded units wrong.
3609 * Fixed doconfig makefile to have doconfig.c as a dependency.
3610 * Fixed bug in resetting commodities (the comm_uid was not being
3612 * Fixed bug in repaying loans not working correctly (the l_uid was not
3613 being properly set.)
3614 * Fixed bug in buying items from the trading block not allowing you
3615 to due to a perceived change in item status.
3616 * Fixed bug in mfir.c where a bogus input to a target could crash
3618 * Fixed bug that after you read telegrams new telegrams may not send
3619 an inform message (the old telegram flags were not cleared.)
3620 * Fixed bug where fort support distance calculations are calculated
3621 twice instead of just once. This bug caused a lower percentage
3622 of support fire than designed.
3623 * Fixed bomb.t to reflect land unit changes.
3624 * Put in some integrity checking for planes returing from bombing runs.
3625 * Added ability to edit land unit that a land unit is loaded on in
3627 * Consolidated bridgefall code into "knockdown" function (this code
3628 existed in at least 3 places, and was different in all of them.)
3629 * Subs returning fire are no longer reported in the news.
3630 * Visitor countries can now use the 'motd' command.
3631 * When trying to use a visitor country, if it is in use, you are not told
3632 by whom, just that it is in use.
3633 * Optimized (slightly) support fire from forts not getting supply and
3634 shells if not needed (out of range)
3635 * Updated Education.t
3636 * Modified (increased) chances of hitting mines slightly.
3637 * Removed unused variables from shp_check_mines.
3639 Changes to Empire 4.0.17 - Fri Jul 31 06:12:21 PDT 1998
3640 * Added ability in edit to change coastal flag for sectors.
3641 * Added ability in edit to edit plague values for ships.
3642 * Added ability for "spy" to report all units/planes not owned by you
3643 that exist in the sector you are spying from.
3644 * Modified naval planes and anti-sub planes.
3645 * Changed so that missiles and bombs that miss their targets cause
3646 collateral damage in the target sector (they have to land somewhere!)
3647 * Changed llook so that non-spy units are required to have at least 1
3648 military personnel on board to see anything.
3649 * Fixed "llookout.t" to reflect change for military requirement.
3652 * Added "lmine" flag for deities to see what sectors have mines in them
3653 (works for sea and land mines, used "lmine" to distinguish it from "min"
3654 which determines mineral (iron) content of a sector.)
3655 * No longer able to pin bomb land units on a ship.
3656 * Land units are required to have at least one military loaded to perform
3658 * Firing land units are required to have at least on military loaded to
3659 be able to fire (or return fire.)
3660 * Spies are not always seen when being pinbombed. You have to look very
3661 carefully for them (as you usually would.)
3662 * Fixed typo in "Spies.t"
3663 * Added new info about spy ability to spy.t.
3664 * Updated tax information in Innards.t and Update-sequence.t
3665 * Fixed typo in fire.t information about units firing on ships.
3666 * Loading military onto land units now resets fortification. (You gotta
3667 re-fortify the new guys.)
3668 * Fixed bug where planes that were mine capable could not drop mines if
3669 they were not cargo capable.
3670 * Fixed bug in potentially crashing in update code for nations tech/research.
3671 * Fixed bug in execute putting you into execute mode incorrectly.
3672 * Fixed bug in board not allowing land units to board from 0 mobility
3674 * Fixed bug where interdicted land units that were missed displayed
3675 a "SPLASH! Bombs miss your ships" message.
3676 * Fixed bug in minesweeping sectors where, even with mobility or
3677 having the sweep ability, ships would get hit by mines for doing
3679 * Fixed bug in count_land_planes always writing out land units unnecessarily.
3680 * Fixed bug in count_planes always writing out ships unnecessarily.
3681 * Fixed bug in lnd_count_units always writing out land units unnecessarily.
3682 * Fixed bug in count_units always writing out ships unnecessarily.
3683 * Fixed bug in llook that reported units on ships.
3684 * Fixed bug in llook that reported satellites launched over the unit.
3685 * Fixed bug in llook that always reported spies (it should be a 10-100%
3687 * Fixed bug in anti possibly not saving lost items correctly.
3688 * Fixed bug in planes getting extended range when on missions and the
3689 op center is not where the plane is located.
3690 * Fixed bug in land unit defensive strength not being based on the eff of
3691 the unit when calculating odds of a battle.
3692 * Fixed bug in board not reporting consistant information.
3693 * Fixed bug in the way land unit casualties were being taken.
3694 * Fixed bug where land units on ships could return fire.
3695 * Fixed bug where land units on other land units could return fire.
3696 * Fixed bug where land units on other land units could fire.
3697 * Fixed bug in attacks/assaults/boardings spreading plague incorrectly.
3698 * Fixed bug in updating plague for ships.
3699 * Fixed bug in updating plague for land units.
3700 * Fixed bug in updating plague for attacking/defending land units.
3701 * Fixed bug where you couldn't pin-bomb land units that were < 20% eff.
3702 * Fixed bug which revealed the owner of torping subs when on a mission.
3704 Changes to Empire 4.0.16 - Fri Jun 12 08:52:06 EDT 1998
3705 * Added patches sent in by Steve McClure, Sverker Wiberg and Curtis
3706 Larsen. They are described with other changes below.
3707 * Fixed bugs in the following commands that allowed two cooperating
3708 countries to create infinite numbers of any commodity and/or cash
3709 at any time (race conditions in the server): build, board, deliver,
3710 designate, distribute, explore, fuel, improve, load, ltend, mobquota,
3711 move, name, order, reset, sail, sell, set, tend, territory, test,
3712 threshold, torpedo, transport, unload
3713 * Fixed bug in board command giving out too much information about a
3714 non-owned sector when it shouldn't be.
3715 * Fixed bug in board command when firing on a sector in defense before
3717 * Fixed bug in rangeedit allowing plane(s) to possibly be stored wrong.
3718 * Fixed bug in launch allowing plane to possibly be stored wrong after
3720 * Fixed bug in lrangeedit allowing land unit(s) to possibly be stored wrong.
3721 * Fixed bug in morale allowing land unit(s) to possibly be stored wrong.
3722 * Fixed bug in arm/disarm allowing a plane to possibly be stored wrong.
3723 * Fixed bug in loan sometimes not writing database correctly.
3724 * Fixed bug in collect.
3725 * Fixed bug in dropping mines from land units.
3726 * Fixed crashing bug in sector_strength routine when oceans take
3728 * Fixed bug in transport possibly decrementing too much mobility when
3730 * Fixed some little warning type messages building with gcc -Wall.
3731 * Fixed problem compiling lwp threads with glibc6 under Linux.
3732 * Changed flash so that players can always flash deities.
3733 * Changed players command to always show deities and visitor countries
3734 that are logged on, and only show allied countries for normal player
3736 * Fixed bug in anti command not stopping sectors when they revolt.
3737 * Fixed bug in set_coastal function not counting bridge spans as
3738 water based sectors (after all, the land is still a coastal sector,
3739 even if next to a bridge span.)
3740 * "flash" and "players" is re-enabled for visitor accounts.
3741 * Fixed bug in bleeding of technology and research to other players.
3742 * Fixed bug in explore not spreading plague correctly.
3743 * Fixed bug in move not spreading plague correctly.
3744 * Fixed bug in deliver not spreading plague correctly.
3745 * Fixed bug in distribute not spreading plague.
3746 * Included "postresults" script in the scripts directory which can be
3747 used to auto-post daily power chart/announcements to rec.games.empire.
3750 * Removed OVCONFIG from build.conf, and patched doconfig to match.
3751 * doconfig is only run if needed
3752 * emp_client and emp_server are only linked if needed
3753 * Added list of disabled options to the version command.
3754 * Fixed bug in survey allowing you to see hidden variables.
3755 * Re-enabled escort missions due to above bug fix most likely the problem.
3756 * Changed one instance of "restrict" to "restricted" in bestpath.c. For
3757 some reason, this was causing a problem on one of the Linux builds (??).
3758 * Added "show sector capabilities" functionality (this didn't exist
3760 * Fixed bug in neweff not reporting stopped sectors. It now (correctly)
3761 reports them as not changing eff.
3763 Changes to Empire 4.0.15 - Wed May 20 12:35:53 EDT 1998
3764 * Fixed the spelling of Markus' name in CHANGES4.0 files.
3765 * Added Markus' patches/fixes. Some are detailed below.
3766 * Added 'mipsultrix.gxx' build target.
3767 * Fixed doconfig to write ipglob.c in the correct target area.
3768 * Fixed a bunch of type casting that needed to be done correctly.
3769 * Only print out last connect by for non-visitor accounts.
3770 * 'players' command is only useable by non-visitor accounts.
3771 * Fixed ask_off in attsub.c to not print out allied sector mil counts
3772 when attacking from neighboring sectors.

3775 * Fixed update not updating timestamps of objects (ships, planes, land
3777 * Fixed bug delivering conquered populace.
3778 * Fixed potential bug scuttling ship with land units on it.
3779 * Moved heavy bombers to tech 90.
3780 * Fixed bug in setsector telling the deity coordinates of sectors being
3782 * Fixed bug in setting budget of enlistment sectors to 0.
3784 Changes to Empire 4.0.14 - Wed Apr 8 08:47:54 EDT 1998
3785 * Fixed time_t problem in common/log.c
3786 * Fixed bug in headlines
3787 * Replaced vaxultrix build flags with proper vanilla ones.
3788 * Fixed bug in update/prepare.c (sometimes not getting charged for
3789 mil on units and ships)
3790 * Fixed bug in printing of "No ship(s)" twice in cargo command when no
3791 ships were selected.
3792 * Temporarily disabled escort missions until a fix is found. They are
3793 randomly crashing the server.
3794 * Fixed morale.t to reflect that retreat percentage is based off of
3795 morale_base and not 75.
3796 * Fixed bug in bridgefall where planes and units on ship in a sector
3797 that has a bridge collapse are being sunk.
3798 * Fixed bug in update/produce.c when a sector overflows it's capacity
3800 * Fixed bug in produce command reporting incorrect costs (sometimes).
3801 * Land units on ships will now try to draw supply from the ship they
3804 Changes to Empire 4.0.13 - Mon Mar 2 11:04:28 EST 1998
3805 * Fixed bug in distribute when world sizes are other than 64x32
3806 * Fixed bug in getcommand (not really a bug, just made it work like
3807 it used to so that the players command is useful for deities
3809 * Fixed building of POSIX threads on Alpha running Digital Unix.
3810 * Fixed line_of_sight prototype in sona.c
3811 * Fixed fairland not to conuse stupid C++ compilers.
3813 Changes to Empire 4.0.12 - Tue Feb 24 11:27:31 EST 1998
3814 * Fixed client build on linux (whoops)
3816 Changes to Empire 4.0.11 - Tue Feb 10 10:53:10 EST 1998
3817 * AIX build seems to only work with gcc right now (but at least that works)
3818 * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box.
3819 * Took out autosupply of airports when bombing or dropping shells.
3820 (This was the only commodity this was done for, and it was creating
3821 problems since supply is still somewhat broken somewhere)
3822 * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
3823 submitted patches, which collectively included cleaning up most
3824 of the server prototypes and bogus declarations. Many thanks.
3825 * Increased incoming command buffer to 1024 from 512 bytes
3826 * Increased the # of parsed arguments from 64 to 100
3827 * Fixed bug where spies were not dying when damaged.
3828 * Fixed bug in HIDDEN mods in declare command not printing country # of
3829 uncontacted country correctly (or at all as a matter of fact)
3831 Changes to Empire 4.0.10 - Mon Aug 18 12:34:58 EDT 1997
3832 * Fixed bug where fleets were being interdicted but the damage was being
3833 spread to ships not in the same sectors.
3834 * Fixed but in market when buying goods without enough cash.
3835 * Planes in orbit over airports are no longer fixed up during updates.
3836 * Planes in orbit are no longer damaged when the sectors they are over
3838 * Planes on ships are no longer damaged when the sectors they are in are
3839 damaged, unless the ship is damaged.
3840 * Fixed problem with no newline after partisan activity telegram in
3842 * Fixed problem in chan.c printing out change costs incorrectly.
3843 * Fixed problem in dispatch.c screwing things up on redirection.
3844 * financial should now handle 6 and 7 digit loans.
3845 * Planes on ships that are in sectors that revolt are no longer taken
3847 * Fixed bug in powe.c where the power report was mis-calculating the
3848 efficiency of planes.
3849 * Fixed doconfig.c to use STDC instead of multi-level #ifdefs.
3850 * Fixed bug in parse.c that was screwing up double quotes in conditional
3852 * Military in a sector now only produce up to maxpop, just like civvies
3853 and uw's. No more stuffing 6K mil into a mountain to max it out. You
3854 can still hold more mil there over the updates, but the extras just
3855 won't produce anymore.
3856 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
3858 * Fixed bug in day of week calculation for server up time in common/keyword.c
3859 that is used for gamedays.
3860 * Documented what happens to standing military in collect.t when you collect
3862 * Documented mountains only holding and using 1/10th of the normal sector
3863 population in Sector-types.t.
3864 * Fixed documentation on ship's firing ranges in fire.t to be less
3866 * Updated nukes in nuke.t
3867 * Added apropos command (thanks to Mike Wise)
3868 * Added case-insensitivity to the info command (thanks to Mike Wise). If
3869 there are two files of the same name, and you don't get a complete match,
3870 then whichever file is found first in the directory is used.
3871 * Changed documentation in wantupd.h
3873 Changes to Empire 4.0.9 - Sat Apr 19 23:01:51 EDT 1997
3874 * Fixed dump info pages that were getting formatted funny.
3875 * Fixed improve info page.
3876 * Fixed bug in allied planes/units not moving when the carriers move.
3877 * Fixed bug in satellite output for <100% satellites.
3878 * Fixed bug in load/unload not putting a newline after some unloadings
3880 * Fixed bug in harden not printing correct values.
3881 * Fixed bug in creating/moving/etc. nuclear stockpiles.
3882 * Fixed bug where subs were trying to torp commodities moving on land when
3883 on interdiction. (This was funny ;-) )
3884 * Fixed bug in "move" where you could keep a sector even after someone else
3886 * Budget now correctly reports the # of units being built.
3887 * Mil on units & ships are now reported as normal military costs, not
3888 ship or unit maintainence costs in budget.
3889 * Fixed bug in update code where taxes could potentially be initialized
3890 incorrectly (affected budgets too.)
3891 * Fixed bug in nat.h header so that it uses SCT_MAXDEF instead of a fixed
3892 number (that was incorrect.)
3893 * Fixed bug with trains - they needed the xlight flag to carry planes.
3894 * Revamped and improved flak.
3895 * Added "Flak" info page.
3896 * Added "Fallout" info page.
3897 * Fixed repay/offer/consider to all need a capital to be used.
3898 * Fixed bug with air defense missions not running when not AT WAR. They now
3900 * plane/ship/unit short names are all now 4 characters, padded if needed.
3901 * pdump/sdump/ldump/ndump now just print the short name for the type.
3902 * sdump now has ship name at very end in quotes.
3903 These were done at the request of some client developers for ease of use.
3904 * Fixed extra space in the dump output.
3905 * Fixed fallout - not quite so nasty anymore.
3906 * Fixed fallout - things on ships/units are damaged now.
3907 * Fixed and balanced planes/ships/units/nukes in conjunction with each other.
3908 * Fixed bug in doconfig.c calculating wrong s_p_etu sometimes.
3909 * Fixed bug where harbors weren't being used to resupply.
3910 * Fixed bug where selling units loaded with planes and units wouldn't take
3911 the loaded planes or units - they are now dropped.
3912 * Fixed bug in arm/disarm where you could arm/disarm planes on the trading
3914 * Deities can now remove things from the trading block/market.
3915 * Fixed bug in "work" not charging engineers enough mob.
3916 * Fixed bug in "work" not adding teardown and buildup avail costs together.
3917 * Subs no longer need mobility to return fire when fired upon.
3919 * Fixed bug in "trade" allowing 2 players to pay for the same item, but only
3920 the last player gets it.
3921 * Fixed bug where you couldn't launch missiles from allied ships or sectors.
3922 * Fixed bombing so that pin-bombing can cause collateral damage too.
3923 * Fixed sector damage to damage planes there too.
3924 * Fixed flag in lload so that it doesn't always print if not needed.
3925 * Fixed "sell.t" info page.
3926 * Fixed bug in "buy" where not entering the price correctly could cause
3928 * Fixed "sell" so that at least 1 mobility is required to sell goods. Keeps
3929 the midnight "raid and sell" abuse down. :)
3930 * Fixed "show plane cap" to move the last column over 1 more where it should
3932 * Fixed timestamps to be updated for units/planes on ships/units that move,
3933 since those units/planes move too.
3935 Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
3936 * Fixed bug in nstr_exec that was wiping out the previous conditional.
3937 This was major because it affected timestamp values which are more
3939 * Fixed bug in sdump.c for typo in reporting the trade ships origin.
3941 Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
3942 * Fixed bug in aircombat.c when calculating the air combat odds. Negative
3943 numbers were screwing things up good...
3944 * Fort sector's coordinates are no longer printed when auto-firing at
3946 * Subs can now surface and fire deck guns (again) They can also be
3947 hit by return fire when doing so.
3948 * Fixed bug in setting of plane attack and defensive values so that
3949 negative numbers don't keep going further negative.
3950 * Fixed incorrect military control calculation in the sell command.
3951 * Trading posts are no longer required to sell goods from. You can sell
3952 from harbors and warehouses now too.
3953 * Spy now prints out the owner of land units you see when spying. Before
3954 this was assumed to be sector owner, which is no longer true.
3955 * Loading land units now prints out what was loaded onto each unit,
3956 just as loading ships do.
3957 * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output.
3958 * Added "GO_RENEW" option. This option means that gold and oil resources
3960 * Added "lost_items_timeout" config variable, and set the default to
3961 48 hours. This determines how long lost items stay in the lost items
3963 * Fixed land unit names to be more consistent.
3964 * Fixed mission.t info page.
3965 * Fixed bug in that if mission_mob_cost was set to 0, even negative
3966 mob units should be able to be put on missions.
3967 * Removed restriction on things needing to be at least 60% to be put
3968 on a mission. Note that while you can put them on missions at < 60%
3969 now, when trying to do the mission, it still checks the eff. This
3970 is to help in automatic setup (build, put on mission, forget) instead
3971 of having to come back repeatedly.
3972 * Spies caught in Neutral or Friendly countries cause the Neutral or
3973 Friendly country to go Hostile towards the owner of the spy.
3974 * Tweaked ammunition numbers for artillery units.
3975 * No more automatic declarations of War should be made. You will go
3976 hostile, but since going to war doesn't increase your countries
3977 defenses, and is purely political, it is left to the player to go
3979 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
3980 * Fixed bug in "lmine" that was crashing the server if the land unit was
3982 * Fixed buy so that if you specify a product, you can only bid on that
3984 * Added "lost.t" info page.
3985 * Added "lost items" database (EF_LOST)
3986 * Fixed bug where you could move in allied forces after an attack if they
3987 bordered the victim area.
3988 * Fixed nstr_comp to deal with values > 16 bits coming in from
3989 client for comparisons.
3990 * Changed last minute market/trade timers to increment 5 minutes. 2 minutes
3992 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
3993 * Commented out the logging of the market checking in server/marketup.c,
3994 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
3995 pretty much useless data that made parsing the server.log file more
3996 more difficult than it needed to be.
3997 * Fixed crashing bug in ldump.
3998 * sdump, ldump, ndump, pdump and dump now print out the current
3999 timestamp on the "DUMP XXX" line.
4000 * Fixed denial of service bug in lib/player/accept.c in
4001 player_find_other function.
4002 * Fixed bug in shark reporting incorrect buyer of the loan.
4003 * Fixed bug in sdump.c (case 0 should have been case 10)
4004 * ldump and sdump now always print the fuel column if asked for,
4005 even if opt_FUEL is turned off. In the case that it is turned
4006 off, the fuel is listed as 0.
4007 * Added "timestamp" field, which is updated every time an item is
4009 * Fixed up the Clients.t info page.
4010 * sdump now prints trade ship building origin.
4011 * sdump now always prints name even if SHIPNAMES isn't defined. If
4012 it is not defined, then the name is empty.
4013 * Added "timestamp" to info/Concepts/Selector.t
4014 * Added some more relevant info to info/Server/Empire4.t
4015 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
4016 is no longer torn down when a sector is re-designated.
4017 * Fixed sell.t to more accurately reflect the time-delay market.
4018 * Fixed read.t and wire.t to reference accept and reject.
4019 * Fixed reject.t not referencing accept command.
4020 * Fixed collect.t to more accurately reflect what goes on when collecting
4022 * Fixed financial.t to reflect defaulted loans.
4023 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
4025 * Fixed "census.t" (had incorrect reference to "info syntax" instead
4028 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
4029 * Increased damage from depthcharges because on increased damage from
4030 torpedos. Sub frange decreased to be more balanced with destroyer frange.
4031 * Intelligence reports (spy) on units will now report the estimated number
4033 * Fixed equation for ship visibility so it will drop as tech increases.
4034 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
4035 land units, planes, and nukes.
4036 * If fields are provided, dump will only supply those fields requested.
4037 * Decreased speed of subs.
4038 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
4039 required for infrastructure improvements.
4040 * Units that lose an assault or a boarding attempt from a ship will no
4041 longer swim back to the ship they came from.
4042 * Units that take extra casualties will no longer lose all their mil at
4044 * Infrastucture is retained when redesignating a sector.
4045 * Dieing spies will no longer crash the server.
4046 * Units, planes, and ships must have mobility to perform missions.
4047 * Units on ship being scrapped are transferred to harbor.
4048 * Food is no longer autoloaded onto units when they are built.
4049 * Fixed show plane stat to show correct range.
4050 * Infantries now take damage at same rate as casualties.
4051 * Fixed bug with hap_fact. Having more happiness now helps with fighting
4053 * Fixed anti to write back target country so che will continue to fight
4055 * Fixed llookout to show correct estimate on number of mil on unit.
4056 * Added buildable architecture "hp". This type will build the server on
4057 a HP/UX machine using the standard compiler instead of gcc.
4059 Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
4060 * Fixed bug in update/distribute.c where pathcost was not being called with
4061 the MOB_ROAD argument (and thus distribution costs could be GREATLY
4062 affected.) - Thanks Ice!
4064 Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996
4065 * Fixed Solaris port using gcc.
4066 * Fixed doconfig.c to create directories with right modes.
4067 * Fixed install macros in makefiles to move binaries to the right
4070 Changes to Empire 4.0.3 - Wed Dec 4 22:46:53 EST 1996
4072 * Fixed doconfig.c (put exit(0) at the end of main.)
4073 * Fixed improve.c (moved the prompt[] string outside the fcn.)
4075 Changes to Empire 4.0.2 - Mon Oct 14 12:26:40 EDT 1996
4076 * Put in LND_MINMOBCOST in land.h
4077 * Put in change in lnd_mobcost in lndsub.c
4078 * Put in new nuke costs in nuke.c
4079 * Put in fix so that total work can only be done by the max pop. No more extra
4080 civvies tossed in will do it anymore in human.c.
4081 * Put in fix for src/util/Makefile - beefed it up.
4082 * Put in fix to show where your ship is when it gets shelled in mfir.c.
4083 * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in
4085 * Fixed Update-sequence.t.
4086 * Put in fix for mobcost bonus for 0% highways.
4089 * Spruced up torpedo damage somewhat. :) :)
4090 * Fixed "assault bmap bug" in attsub.c
4091 * Fixed Produce.t (bars cost)
4092 * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
4096 * Fixed "offer" and "consider" not being legal commands in player/empmod.c
4099 * Fixed lstat.c, pstat.c and sstat.c
4100 * Fixed cutoff command in cuto.c
4101 * Fixed attack value in attack_val in lndsub.c
4102 * Fixed lload in commands/load.c
4103 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
4104 always fight until dead or retreating. 0 makes them get stuck.
4105 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
4106 else for that matter.)
4107 * Fixed llook in commands/look.c
4108 * Fixed che bug in subs/nstr.c
4109 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
4110 of people would starve.)
4111 * Fixed update/human.c - feed_people rounding problems (I hope.)
4112 * Fixed morale problem in update/land.c
4113 * Fixed count_bodies in attsub.c
4114 * Fixed lnd_mobcost.
4115 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
4116 * Fixed interest rate in commands/offe.c
4117 * Fixed bug in buy.c.
4118 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
4119 infrastructure. When off, the defensive infrastructure is the same
4120 as the sector efficiency, and you can't improve it. This is OFF by
4124 * Land units are now built with a default reaction radius of 0.
4125 * Changed name of lt artilleries to "lat" from "lart" so you can now build
4127 * Lowered the speed and firing range of pt boats.
4128 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
4130 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
4131 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
4132 1.5 * ETU_RATE for ships.)
4133 * Conquered civvies only pay 1/4 taxes.
4134 * Railways don't get torn down when you rebuild sectors anymore (but roads
4135 and defenses do (if enabled.)
4137 Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
4138 * Added "extern double tradetax" to check_trade in trad.c
4139 * Improved description of data directory in build.conf
4140 * Fixed bug in attacking land units that retreat so they now get
4141 charged mobility for attacking.
4142 * Fixed dump to report road, rail and defense of a sector at the end.
4143 * Fixed doconfig bug in not checking the right directory to see if the
4144 "data" directory existed or not before trying to create it.
4145 * "change" now works for sanctuary countries.
4146 * Fixed the description of "sinfrastructure".
4147 * Added more info to "Infrastructure".
4148 * Units/planes are no longer reduced to 75% when bought from the trading
4150 * Supply units were slowed down to the speed of infantry units.
4151 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
4152 * Bars interest is up to $250 per 1K again.
4153 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
4154 * Fixed various info pages.
4155 * Fixed bug in people not getting truncated when broke (this was thought
4156 to be fixed, but wasn't. Now it is, dammit!)
4157 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
4158 * Market/trade taxes and trade ship payoff figures were added to version.
4159 * "cede" has been removed as a default command.
4160 * Makefile rule was fixed for depend build.
4161 * Fixed bug in mapdist not taking world edges into account nicely enough.
4162 * Added a "scuttle" order for autoscuttling trade ships. Makes using them
4163 easier. Cleaned up scuttle code while in there.
4164 * Fixed bug with scuttling a ship with units on it not scuttling the units
4167 Changes to Empire 4.0.0 - Wed Aug 21 1996
4168 * Initial Wolfpack release - Long live the Wolfpack!!!!
4169 * Cleaned up the build environment. Now all that is needed is to edit the
4170 build.conf file, answer the questions there and type "make <arch>" to
4171 build for a specific architecture. Thus, no more reliance on gnumake
4172 or special shell scripts.
4173 * We are now shipping the pre-built info pages with the server for those who
4174 Don't want to build them. You can also still just type "make" and have
4175 the info pages build, but it doesn't completely work (i.e. rebuild new
4176 Subjects) if you don't have perl5 installed.
4177 * Put in the "help" command that does the same thing as "info".
4178 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
4179 wish to support it. 2) We envision a better scheme for doing similar
4180 things will come along.
4181 * Put in MOB_ACCESS - This allows real-time updating of mobility.
4182 * Put in MARKET - This is the time-based market (yes, still teleports,
4183 but it's not as bad as it was.)
4184 * Lots of the documenation has been updated, but there is more to do.
4185 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
4186 enabled, you don't need any of that type of material to build things.
4187 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
4188 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
4189 any materials to build a bridge.
4190 * There is no mobility cost for assigning missions. But, there is also
4191 no longer any benefit for being on a mission either.
4192 * Damage is the same for all commodities (people too.) This means you
4193 can deity shell/bomb sectors again.
4194 * Units are now dependant on tech. What this means is that their statistics
4195 now increase with tech. In addition, there is only 1 type of each basic
4196 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
4197 This reflects the idea that as you learn more, you learn how to not only
4198 build better units, but you learn to build units better. :) This also
4199 opens the door for a "lupgrade" command along the same lines as the
4200 "upgrade" command for ships.
4201 * Units now have a minimum mob cost for attacking a sector. Marching
4202 mob costs have not changed.
4203 * Starting units have been removed. This means that at the beginning, people
4204 may live a little longer since their neighbor can't come visiting quite
4206 * Shells are no longer required to build units.
4207 * Mil are no longer required to build units.
4208 * Mil are no longer an intrinsic part of a unit. They are now a loadable
4209 commodity. The way a unit's defense/att bonuses work now are
4210 attack = (att * mil * eff)
4211 defense = (def * mil * eff)
4212 In addition, when a unit takes damage, both the eff and the mil go
4213 down. You can quickly toss in new hacks, but you need to wait to repair
4214 the unit at the update. Thus, you can now look at unit's efficiency
4216 * You need at least 1 mil on a unit to march it (spies are the exception.)
4217 * Units always react if in range and they have the mobility, no matter
4218 what their efficency.
4219 * Units may now march anywhere - in your own sectors, deity owned sectors
4220 or allied sectors, with 1 exception, spies. Also, your units can get
4221 trapped if your ally declares non-alliance with you while your units
4222 are still in his country.)
4223 * Units always march at their speed, efficiency doesn't matter.
4224 * LANDSPIES was added - This creates land unit based spies. Spies may march
4225 anywhere, with a chance of getting caught (except in allied territory.)
4226 See "info Spies" for more info on them.
4227 * Planes may now be based out of allied airports. Landing planes on
4228 ships/sectors you do not own no longer changes thier owner. You can only
4229 land on owned/allied sectors/ships, and you may only
4230 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
4231 you are allied with goes hostile at you, your planes are now stuck there.
4232 Note that if you are using an allied airport, their commodities get
4233 sucked up, not yours (obviously.)
4234 * Planes are now tech-based. Their statistics increase as their tech
4235 increases. Deleted extraneous planes.
4236 * There is a new toggle, "techlists", which allows you to see what you
4237 can build/stats/capabilities sorted by tech instead of groupings.
4238 * Ships are now tech-based. Their statistics increase as their tech
4239 increases. Deleted extraneous ships.
4240 * Che can now be lessened by making happiness. If you have more happiness
4241 than your conquered populace, they don't fight as hard or recruit as
4242 much. If you have less than them, they fight harder and recruit more.
4243 It's not much though - it ranges from 2.0 in your favor to only 0.8
4244 against you (whereas it was always 1.0 before.) So, it definitely
4245 favors the attackers to make lots of happy now.
4246 * Bridgeheads can only be built on coasts.
4247 * Players command was fixed so you only see allies, and don't get
4248 approx #'s of players anymore.
4249 * POSIX threads support has been added.
4250 * The attack bmap bug has been fixed.
4251 * BTUs regenerate 3 times faster now.
4252 * GRAB_THINGS is off by default.
4253 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
4254 as a default (you couldn't make wasteland before with FALLOUT, now
4256 * You can now deliver military and civilians.
4257 * Added SHIP_DECAY option - off by default (turns off ships decaying out
4258 at sea if not enough mil.)
4259 * The reverting owner bug has been fixed in territory, thresh, dist
4260 and deliver. There are probably more, and when found, will be fixed.
4261 * The "sectors don't starve when stopped or broke" bug has been fixed.
4262 * The "people never get truncated" bug has been fixed.
4263 * Added infrastructure to sectors. What this means is that a sector
4264 can now have it's mobility improved by building both roads and
4265 railways. It also means that a sectors defense is now based on the
4266 defensive infrastructure you build into the sector (no more intrinsic
4267 better defenses based on the sector, you determine which sectors are
4268 defended heavily, and which aren't.)
4269 * The defensive value of a sector no longer relies on the efficiency of
4270 the sector. Instead, it relies on the defensive efficiency of the sector.
4271 Thus, the "production" and "defensive" aspects of sectors have been
4273 * "show sect stats" now shows the maximum defensive value for sectors.
4274 * Changed sector structure to take floats for off/def values so we can use
4275 a base of 1 instead of 2.
4276 * Added "improve" and "sinfrastructure" to support the infrastructure
4278 * Added L_TRAIN units which can only travel along railways. Very fast on
4279 efficient railways, slow on non-efficient ones.
4280 * Added the ability for units to carry other units.
4281 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
4282 * Forts only cost $500 to build and 100 hcms now (since they don't get any
4283 better defenses automagically.)
4284 * Modified "show sect build" to show the costs for building up the
4285 infrastructure of a sector.
4286 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
4287 spyplanes too) to show the new infrastructure stuff, rounded of course.
4288 * Added Drake's info->html scripts, with some modifications, so you can
4289 now type "make html" and have your info pages built as html files too.
4290 This adds a new directory, "info.html", to the build tree.
4291 * Modified upgrade so that planes and land units may now be upgraded.
4292 * Added pstat command to list the statistics of your planes.
4293 * Added lstat command to list the statistics of your land units.
4294 * Added sstat command to list the statistics of your ships.
4295 * Added nmap command to show a map of your sectors after their new
4296 designations have taken place.
