1 Changes to Empire 4.3.30 - Sat May 5 14:12:11 UTC 2012
2 * Fix some buffer overruns in fairland. Has always been broken.
3 * Fix arm to require nuke and plane to be in the same sector. A
4 remote nuke got teleported to its plane when the plane moved.
6 * Change login command kill (used by client option -k) to kill less
7 ruthlessly: send a flash message and try to flush output, exactly
8 like a server shutdown does.
9 * Fix server shutdown to wait for player threads to reach a safe
10 state. Before, player threads raced with shutdown, and failed to
11 update the treasury, record play time, and write log entries when
12 they lost. Bug goes back to Empire 2. Patched partially or
13 unsuccessfully in 4.2.10, 4.2.12, 4.2.20, 4.3.6, 4.3.10 and 4.3.23.
14 The race was hard to lose in practice, until an unrelated
15 "simplification" in 4.3.23 could get player threads stuck sending
16 output after shutdown aborted a command.
17 * Idle timeout changes:
18 - The grace period for clients to complete login and logout is now
19 separate from the idle timeout. Configurable with new econfig
20 key login_grace_time, default is 120 seconds.
21 - The idle timeout for visitors is now separate from the one for
22 players. Configurable with new econfig key max_idle_visitor,
23 default is five minutes.
24 - Fix the idle timeout when the connection gets stuck sending
25 output. Broken in 4.3.20.
26 - Idle timeout during execute now terminates the connection, not
27 just the execute command.
28 * Fix stack smash in build. Remote hole! Broken when Empire 2 added
29 the confirmation prompt.
30 * Fix stack smash in scrap and scuttle. Remote hole! Broken when
31 Chainsaw added the confirmation prompt. Additionally, the
32 confirmation prompt is misleading when the player supplies
33 conditionals. Redesign the flawed prompt.
34 * Fix execute's echo of the command. Broken in 4.3.28.
35 * The mobility cost of retreating a defending land unit was
36 calculated for an uninitialized sector. This could charge
37 incorrect mobility, prevent retreat, or, if the stars align just
38 right, crash the server. Broken in 4.3.6.
39 * Commands cutoff, headlines, land, lstat, motd, neweff, payoff,
40 qorder, sorder, and wall now behave like the other information
41 query commands when the player's connection can't take more output:
42 they pause to let other code run.
43 * Revised command permissions:
44 - arm and disarm no longer require money, for consistency with the
45 other commands to move stuff around.
46 - satellite no longer requires money, for consistency with lookout,
47 radar, sonar and skywatch.
48 - qorder, sorder, survey and test no longer require a capital, for
49 consistency with the other commands that report on stuff the
51 - start and stop no longer require a capital, for consistency with
52 the other commands to control production.
53 - fortify now requires a capital, for consistency with mission,
55 - Anybody may now use country, echo and financial.
56 - Visitors can no longer use census, commodity, map, nmap,
57 sinfrastructure (useless without sectors), read (visitors don't
58 get any telegrams), and change (always failed).
59 - Players can no longer use map and nmap before break. This is
60 consistent with all the other commands to examine the
61 environment. It also prevents people from trying multiple
62 unbroken countries in a blitz to find the one with the nicest
64 - Players can now use resource before break, just like census.
65 * read could swallow the first telegram header when showing the
66 telegrams that arrived while waiting for the player to confirm
67 deletion. Broken in 4.3.29.
68 * Fix 'm' in path argument of explore, move, transport:
69 - Don't moan about deprecated argument syntax ('m' without a space
70 before its argument) even when there's no argument.
71 - Recognize the flags argument again.
74 - Command market is no longer available to visitors, because it
75 triggers execution of trades that have become ready.
76 - Fix a race condition that could cause commodity trades to be
77 executed multiple times. Abusing this to duplicate commodities
78 seems tricky, but possible. Broken in Empire 3.
79 - Don't expropriate sellers of units. POGO got the the money, the
80 telegrams and made the news, the seller got nothing. Broken in
82 * Login command quit and server shutdown could lose player output.
83 4.3.23 tried to fix the shutdown case, but the fix was incomplete.
84 * Fix login command quit to really quit. It sometimes just swallowed
85 buffered input, at least on some systems.
86 * 4.2.22's fairer command scheduling failed to cover the execute
88 * When a client shuts down input transmission to log out, output
89 could get lost. Our client never does that.
90 * Don't skip post command treasury update and status notification on
91 EOF from player, after quit command, and when command is aborted by
92 server shutdown. An unluckily timed EOF or shutdown can deprive a
93 player of money gained from scuttling tradeships or sacking a
94 capital. Can be abused to build bridges and infrastructure free of
95 charge. Can also be abused to designate sectors for free, but the
96 stock game's sector types are all free anyway. Has always been
98 * Fix client not to send an empty line on player interrupt (normally
99 ^C) before the first command. This was missed in 4.3.26.
100 * Code and info page cleanup.
101 * Documentation fixes.
103 Changes to Empire 4.3.29 - Fri Jan 20 19:20:20 UTC 2012
104 * drop and fly from carrier could fail to load last civilian or
106 * Telegram and announcement changes:
107 - wire no longer loops to show announcements that arrived while
108 waiting for the player to confirm deletion.
109 - At most five seconds worth of messages are now squashed together
110 into one. Before, only the time between adjacent telegrams was
111 limited, not the total time.
112 - When telegrams arrived while read was waiting for the player to
113 confirm deletion, and we then showed them, we nevertheless
114 claimed "you have new telegrams" before the next command prompt.
115 Only with toggle inform off. Known bug since Empire 2.
116 - Fix read not to clobber asynchronous notification of telegrams
117 arriving while waiting for the player to confirm deletion.
118 - Fix wire not to reset number of pending telegrams with toggle
119 inform on. Broken when Empire 2 introduced toggle inform.
120 - The number of pending announcements was off when announcements
121 were squashed together.
122 - More careful error handling and logging.
123 * Ensure all of an update's output goes into a single production
125 - Avoid splitting it up when the update is slow. Empire 2 already
126 did that for the number of pending telegrams, but not for read.
127 - Don't turn parts of it into BULLETINs. Autonav and sail could do
129 * files now creates POGO with user interface flags beep, coastwatch,
130 sonar and techlists set, for consistency with add.
131 * Change newcap back to not wiping the country (it wiped since
132 4.3.12). Additionally, leave levels and telegrams alone.
133 * Changes to deity command add:
134 - Require confirmation for unadvisable actions.
135 - Refuse to touch a country while it's being played.
136 - Don't crash on negative country number.
137 - Create deities with money, just like files creates POGO.
138 - Always reset the country completely, not just when adding a
140 - Rename argument "new" to "player". Keep recognizing "new" for
141 now, but deprecate it.
142 - Drop argument "active". If you really want to create a player
143 country without a capital, add the player country normally, then
144 activate it with edit instead of newcap.
145 - Drop the obscure sector check and wipe option. If you really
146 need to wipe out a country, there's much more to wipe than just
148 - Drop the undocumented land unit destruction feature.
149 * Permit no-op country name change again. Accidentally outlawed in
151 * Plug a few minor memory and file descriptor leaks.
152 * Fix use-after-free when plane gets shot down or aborted in
153 dogfight. Broken in 4.3.27.
155 * Info page and manual page fixes.
157 Changes to Empire 4.3.28 - Sat Jul 16 11:30:53 UTC 2011
158 * Don't let POGO (#0) navigate dead ships, and march dead land units.
159 The ghosts even got sighted and interdicted, and could hit mines.
160 Has always been that way.
161 * llook can't see land units and planes loaded on land units anymore.
162 * Fix board to ignore land units loaded on land units when testing
163 whether a sector can board. Broken in 4.0.17.
164 * Fix transport to reject planes loaded on land units. The plane
165 remained on its carrier. When the land unit moved, the plane was
166 teleported right back to it. Broken since Chainsaw 3 added land
168 * Fix lradar not to let land units loaded on land units use radar.
169 Broken since 4.0.0 added trains.
170 * Fix strength to ignore land units loaded on land units. Broken in
172 * Fix navigate and march to find paths longer than a few sectors
173 again (7 for 64 bit hosts, 3 for 32 bit hosts). Broken in 4.3.27.
174 * march sub-command 'i' now shows number of military and land units
176 * New server option -F to force start even when state looks bad.
177 Risks crashes and further corruption, but gives deities a chance to
178 fix up a bad game state with edit commands and such.
179 * empdump -x no longer refuses to export game state that looks bad.
180 Gives deities another tool to fix up a bad game state.
181 * Land units loaded on land units fight che again, as they used to
183 * When a land unit dies fighting che, land units loaded on it get
184 unloaded, and planes loaded on it die. Before, the update left
185 them stuck on their dead carrier. Impact like the next item.
186 Abusable. Broken since Chainsaw 3 added land units.
187 * The update no longer destroys ships, planes and land units for lack
188 of maintenance. Before, it left any embarked planes, land units
189 and nukes on their dead carrier. In this state, units behaved as
190 if their carrier was still alive, with additional protection from
191 the fact that a dead carrier can't be damaged or boarded. If
192 another unit with the same number got built, it picked up the stuck
193 cargo. The cargo got teleported to its new carrier when the
194 carrier moved. Abusable, but it involves going broke, so it's
195 rarely practical. Slightly more practical before 4.3.6 removed
196 budget priorities. Broken for ships and land units when Empire 2
197 added their maintenance cost, and for planes when 4.3.3 replaced
198 nuclear stockpiles by nuke units.
199 * Fix bogus internal error triggered by navigate and march
200 sub-commands 'r', 'l' and 's'. Broken in 4.3.27.
201 * Fix client not to reject redirections and execute containing
202 non-ASCII characters with a bogus scary warning when using UTF-8.
203 * Fix execute not to mangle non-ASCII characters in the argument when
204 prompting for it while login option utf-8 is on.
205 * Fix handling of non-ASCII and control characters in batch files.
206 * Conversion from UTF-8 to ASCII ate the character following a
207 replaced non-ASCII character. Buffer overrun possible if the
208 terminating zero gets eaten. Could happen in players, read, flash,
210 * Fix handling of empty commands:
211 - Time used was not updated.
212 - Mortal player wasn't logged off for game hours, game down, and
214 - Notifications were delayed: going broke, becoming solvent, new
215 telegrams (toggle inform off only), new announcements, capital
217 * Minor tweaks to nightly build.
218 * Server's and empdump's sanity checking of configuration and game
219 state is now more rigorous.
220 * Deity xdump no longer dumps unused countries' realms.
221 * Remove option LANDSPIES. Deities can customize the land table to
223 * Remove option TRADESHIPS. Deities can customize the ship table to
225 * Configuration table changes (builtin and custom):
226 - Rows must be in ascending uid order.
227 - Omitting rows in tables item, sect-chr and infrastructure is no
229 - Custom tables now replace the builtin table completely. Before,
230 omitted rows defaulted to the builtin version, except at the end
231 of a table. Commenting out unwanted stuff just works now.
232 - Permit custom table product having fewer than 14 entries.
233 - Reject custom tables where customization has no effect (updates,
234 table, meta, all symbol tables) or where it's unsafe (news-chr).
235 - Input is checked more rigorously.
237 - Don't touch plane file when import fails.
238 - Refuse import of incorrectly sized table instead of silently
239 creating one the server will reject.
240 - Replace old state completely. Before, omitted rows in the dump
241 defaulted to the old state, except at the end of a table.
242 - Input is checked more rigorously.
243 * Fix xdump updates not to dump bogus extra updates.
244 * Fix use-after-free when a plane got shot down or aborted by flak.
246 * Friendlier diagnostics in the build command.
247 * Fix build to set nuke's tech exactly like for ships, planes and
248 land units. It's not currently used for anything.
249 * Research required for nukes was slightly off sometimes due to
251 * Bridge building required 0.005 tech less than advertised, fix.
252 * "show nuke" now obeys toggle techlists.
253 * Fix "show land s" to show columns xpl and lnd again. Broken in
255 * Code refactoring and cleanup.
256 * Documentation on custom tables and xdump updated.
259 Changes to Empire 4.3.27 - Sun Apr 17 11:36:29 UTC 2011
260 * License upgrade to GPL version 3 or later.
261 * Fix buy not to wipe out concurrent updates. Can be abused to
262 duplicate commodities.
263 * Don't let fighters, SAMs and ABMs intercept while on trading block.
264 * Don't let missiles interdict ships or land units while on trading
266 * Fix client to log long input lines untruncated.
267 * Fix client crash for long input lines.
268 * info subject pages now mark unusually long pages with a !.
269 * The edit command keys deprecated in 4.3.15, 4.3.17 and 4.3.20 are
271 * Fix give, setsector and setres not to wipe out concurrent updates.
272 * Fix explore, move, test, transport not to ignore spaces in path
273 arguments. Broken in 4.3.7. Deprecate use of 'm' without space
275 * Improvements to map drawing commands:
276 - Don't fail silently when asked to draw a map around an invalid
277 unit, explain the problem.
278 - Deprecate bmap flag "r". Use (a prefix of) "revert" instead.
279 - bmap flags following "t" are no longer ignored. However, info
280 pages previously documented an argument "true" in addition to
281 flag "t". To keep that working, keep ignoring flags following
282 "t" when they're bad. But deprecate that usage.
283 - Reverting the bmap no longer draws a map.
284 - Bad conditionals could make the commands misinterpret their first
286 - The commands now fail when they reject their second argument.
287 * The xdump syntax deprecated in 4.3.12 is now gone.
288 * Fix satellite to fail on bad conditionals instead of ignoring them.
289 * Journal improvements:
290 - Optional logging of output.
291 - Long lines are no longer truncated.
292 - Login phase input is now logged, too.
293 - Commands are now logged. Allows making sense of input without
295 * Option BRIDGETOWERS is now disabled by default.
296 * Bridge towers now take 300 hcms to build, down from 400.
297 * Fix stop orders to expire even when the country is broke. Broken
299 * Fix march and navigate not to advise on "legal directions" when
302 - Much faster, especially for distribution, i.e. where it matters
303 most. Speedups in excess of 30x have been observed for updates
304 taken from real games.
305 - Old land path finder leaked memory occasionally.
306 - Old land path finder overran buffers for very long paths. A
307 malicious player can arrange sufficiently long paths, but it
308 takes a lot of land. Distribution, the distribute command, land
309 unit reaction, and automatic supply now handle arbitrary long
310 paths. Commands explore, move, test, transport, march, navigate
311 and path now handle paths up to 1023 characters. Command
312 bestpath shows paths longer than 1023 characters with the tail
314 - Old sea and air path finder treated destinations as unreachable
315 when the best path was longer than 99 characters. Command sorder
316 now handles arbitrary long paths. Commands bomb, drop, fly,
317 paradrop, recon, sweep and sail now handle paths up to 1023
318 characters. Autonav considers up to 1023 characters at the
319 update. Planes can fly missions up to 1023 sectors from their
321 * Automatic supply charged mobility for the path back to the source
322 instead forward to the sink.
323 * Make bestpath work for deities in foreign land.
324 * More robust savecore example script.
325 * Fix buffer overruns in the lookout, spy, map and nmap commands when
326 WORLD_X * WORLD_Y is not a multiple of 16.
327 * The path command's maps weren't always fitted to the path
328 correctly. Broken in 4.3.17.
329 * Land units no longer hit allied mines.
330 * Change sharebmap with yourself to do nothing instead of telling you
331 you're not friendly to yourself.
332 * You can now flash yourself. Enjoy!
333 * A race condition could make the flash command claim an ally was not
334 logged on when he was. Hard to trigger outside the lab.
335 * The flash command no longer prints "Flash sent" for deities. It's
336 annoying. It never did that for mortals.
337 * Plug memory leaks in mission code on a number of conditions:
338 - Submarines moving where own planes would interdict hostile
340 - Ground combat where countries hostile to one of the parties would
341 support if relations were right (allied to one party, at war with
343 - Ships or land units moving within hostile missile mission op
345 - Any player action within marine missile mission op areas that
346 could trigger the missile owners' missions.
348 - When you ordered a sector to attack with military, but lost the
349 sector before the attack was executed, and the new owner was
350 allied to you, the server got confused: it let the military
351 attack even though they were already dead, but not occupy.
352 - When you ordered a land unit to attack from an allied sector, and
353 the sector got lost before the attack was executed, the server
354 reported things as if you had owned the sector yourself. The
355 land unit still attacked when the new owner was also allied to
357 - When a land unit attacked out of an allied sector, its mobility
358 cost was computed as if the ally owned the land unit. Attacking
359 sectors old-owned by that ally was too cheap, and taking back
360 one's own was too expensive.
361 * Fix trade ships to pay off in own harbor. Broken in 4.3.17.
362 * Remove option SLOW_WAR. It hasn't been enabled in a public game
363 for years, and the code implementing it was buggy.
364 * Fix a bug in sail that limited the sail path to 27 instead of the
365 intended 28 characters.
366 * Fix race condition in transmission of flash and telegram
367 information messages that could double output and possibly crash
369 * Planes get to sweep and sonar only after flak and interception.
370 * Don't limit the radar command's range to fit its output into a
371 world map without clipping. The limiting goes back to Chainsaw 2.
372 * Make flak vs. pinpoint bombing consistent with ordinary flak:
373 - 4.3.6 reduced the plane abort chance on damage, but missed the
374 additional flak vs. pinpoint bombing. Fix that.
375 - Fix to charge mobility appropriate for damage.
376 * Prettier flak damage reporting.
377 * Fix bugs that could cause bmap updates from recon and satellite to
379 * Fix lookout to properly report sector ownership to deities.
380 * Suppress bogus messages deities with non-zero country number got
381 when attempting to navigate foreign ships or march foreign land
382 units. Such deity use hasn't worked since Empire 2.
383 * Deities can no longer fly foreign planes. It didn't fully work
384 since Chainsaw 3, and can trigger internal errors since 4.3.11.
385 * Don't split lines over several bulletins. The read command
386 normally merges these bulletins, but if they are more than five
387 seconds apart (clock jumped somehow), we get a bulletin header in
388 the middle of a line. Broken since Empire 2.
389 * Don't beep when plane, land unit or nuke die on a collapsing
390 bridge. Not nice, because it could beep many times, and could put
391 beeps in bulletins. Beeping was added in 4.0.18.
392 * Minor improvements to nuclear damage reporting.
393 * When a deity dropped a foreign nuke, parts of the output went to
394 the owner of the nuke instead of the deity.
395 * When a player triggered a foreign missile launch (mission or
396 interception), and the missile exploded on launch, part of the
397 report went to the player instead of the missile owner. This
398 disclosed the missile owner's origin. Broken in Empire 2.
399 * When autonav reported to a ship owner that it can't load or unload
400 foreign civilians, it used the sector owner's coordinate system.
401 This disclosed the sector owner's origin. Abusable.
402 * When nuclear damage bounced off a sanctuary, the bulletin to the
403 sanctuary owner used the attacker's coordinate system. This
404 disclosed the attacker's origin.
405 * When a deity used sweep, lmine, sail or sabotage with a foreign
406 plane, land unit or ship, its location was reported in the foreign
408 * When a deity asked for a foreign nation report, the capital
409 location was reported in the foreign coordinate system.
410 * Code refactoring and cleanup.
411 * Info file improvements.
413 Changes to Empire 4.3.26 - Mon May 24 16:37:40 UTC 2010
414 * Land units loaded on ships or land units can no longer fight che.
415 * When foreign land units were present, a che revolt could damage
416 them instead of the defending land units. This could let defenders
417 survive the revolt. They were captured or blown up if che took
419 * Fix che revolt to damage only land units that actually fight
420 * Fix loading x-light missiles on ships without capability plane.
421 These ships could only use their x-light slots for x-light planes,
422 not their plane slots. Broken in 4.3.17.
423 * Update bmap when nuclear detonation makes wasteland.
424 * Fix fly and drop to report discarded cargo items correctly.
425 * New client option -s to specify server host and port.
426 * Hitting landmines could crash the server. When not, the damage
427 reduction for capability engineer was applied unpredictably.
429 * Fix retreat and lretreat condition 'c'. Broken in 4.3.16.
430 * coastwatch and skywatch could see too far. Up to one sector for
431 practical radar ranges.
432 * skywatch now reports satellite uids. The uid is required for
433 launching a-sats since 4.3.23.
434 * Fix client not to send an empty line of input before aborting the
435 command on player interrupt (normally ^C).
436 * Fix sabotage not to kill the spy every time. Broken in 4.3.17.
438 * Info page fixes, manual page improvements.
440 Changes to Empire 4.3.25 - Sun Mar 21 08:27:37 UTC 2010
441 * Hitting seamines could crash the server. When not, the damage
442 reduction for capability sweep was applied unpredictably. Broken
444 * When an interdiction did damage other than collateral damage, the
445 planes that intercepted it from interdicted carriers used no
446 petrol. 4.3.24 fixed only the "no damage" case.
447 * Ship anti-missile defense failed to charge shells when the ship was
448 interdicted. The fix in 4.3.24 covered only launch.
449 * Fix a bug in navigate and march that let players lay mines free of
450 charge. Also fix them not to prompt for the number of mines.
451 * Missile exploding on launch could not damage its base if it was
452 armed with a nuke. Broken in 4.3.23.
453 * When a torpedo attack triggered a return torpedo, the news reported
454 it to be fired by the attacker instead of the defender.
455 * Interdiction attacked submarines with surface-only weapons. Broken
457 * Fix a bug in lradar, path, radar, route, satellite, sect and survey
458 that could leak maps to other players. Broken in 4.2.0. Fixed in
459 4.2.8 for bmap, lbmap, lmap, map, nmap, pbmap, pmap, sbmap and smap
461 * files could clobber the game when reading confirmation fails.
462 * fairland no longer rejects small worlds without trying.
464 Changes to Empire 4.3.24 - Tue Jan 26 21:29:14 UTC 2010
465 * The client sometimes hung under Windows when the server closed the
466 connection. Broken in 4.3.23.
467 * Fix navigate and march not to crash the server when a path argument
468 consists of a valid path plus whitespace. Broken in 4.3.7.
469 * When a client sent a blank line in the login phase, the server
470 crashed on some systems.
471 * Fix crash bug in bomb, drop, fly, paradrop, recon and sail. Broken
473 * Fix bogus internal error on escort, recon, and satellite launch.
474 Mostly harmless, as error recovery worked fine. Broken in 4.3.23.
475 * Stop ship and land unit movement on interdiction even when it does
477 * When an interdiction did no or only collateral damage, the planes
478 that intercepted it from interdicted carriers used no petrol, and
479 interdicted land units were immune to collateral damage.
480 * The limit for the number of sectors, ships, planes, land units,
481 nukes, and so forth is now large enough not to matter. It used to
482 be 32768 on common machines. The sector limit was introduced in
483 4.3.12. World x- and y-size are still limited to 65536 on common
485 * News use much less space, and thus I/O. Space was wasted in
486 4.3.12. Side effects of the change:
487 - Expiry of old news no longer updates news timestamps. Updating
488 timestamps was wrong, because it defeated incremental xdump news.
489 - The empdump utility can no longer update timestamps of imported
490 news. Unfortunate, as it breaks incremental xdump news.
491 * New news selector duration, the time span covered by this news item
493 * ABMs failed to charge supplies when their sector was the
494 intercepted missile's target. The stock game's ABMs use no
496 * Ship anti-missile defense failed to charge shells when the ship was
497 the missile's target.
498 * Code refactoring and cleanup.
500 Changes to Empire 4.3.23 - Sun Dec 13 16:34:49 UTC 2009
501 * Fix missile interception not to intercept tactical and marine
502 missiles attacking missiles or satellites. No such missiles exist
503 in the stock game. Interception of tactical ABMs could crash the
504 server. Broken in Empire 2.
505 * Missiles missing their target do collateral damage again. Was
506 disabled because of bugs in 4.0.18 for manual launch and in 4.3.16
507 for automatic launch.
508 * News reported victim as actor for sub-launched anti-sat and ABM.
509 * Defense value of missiles vs. ABMs and satellites vs. anti-sats
510 failed to improve with tech.
511 * Fix a bug that let missiles interdict ships outside their op area.
512 This could happen when a group navigating together was partly
514 * Only bomb strategic and launch at sector can use nukes. Before,
515 they could also be used by missions, bomb pinpoint, and launch at
516 ships, but there were several bugs and inconsistencies, and the
517 code was messy. The arm command now rejects marine missiles in
518 addition to satellites, ABMs and SAMs, and clears the mission. The
519 mission command now rejects planes armed with nukes.
520 * Missiles exploding on launch pad no longer set off their nukes.
521 * The launch command now more accurately reports why a missile can't
522 be equipped. It no longer draws supplies automatically.
523 * Manually launched anti-sat now always kills when it hits, for
524 consistency with automatically launched ones.
525 * Don't permit nukes on satellites, ABMs and SAMs. Nukes on
526 satellites could be armed and disarmed even in orbit. Nukes on
527 ABMs and SAMs were lost without effect when their missile
528 intercepted. The stock game is not affected, because its
529 satellites, ABMs and SAMs all have zero load.
530 * Remove obsolete plane capabilities stealth and half-stealth. Not
531 used by the stock game.
532 * Penalize fighter combat value for any load, not just bombs. The
533 stock game's fighters can't carry anything but bombs.
534 * Make bomb work for non-tactical cargo bomber. No such planes exist
536 * Revised cargo plane rules: a cargo flight can be either an airlift
537 or an airdrop now. Airlifts carry more cargo than airdrops. A
538 cargo drop or paradrop with a non-VTOL plane is an airdrop.
539 Anything else is an airlift. This makes paradrop loads consistent
540 with drop loads. Paradrop with VTOL transports now carries twice
541 the punch, and drop with non-VTOL transports hauls less than fly.
542 In particular, the stock game's tr can't drop guns anymore.
543 * Enforce plane selection rules more tightly:
544 - bomb command can select only planes with capability bomber or
545 tactical. Before, other planes with non-zero load flew along,
546 but their bombs were silently lost.
547 - sweep command can select only planes with capability sweep.
548 Before, other planes performed ordinary reconnaissance instead.
549 - drop command can select only planes with capability cargo.
550 Before, other planes flew along but dropped nothing.
551 * Fix paradrop to fail without destroying the paratroopers when the
552 player owns the target sector.
553 * Launching an anti-sat now takes the target plane as argument.
554 Before, it took a sector argument, and targeted the lowest-numbered
555 satellite there. Rather inconvenient when your own satellite masks
557 * Remove option PINPOINTMISSILE. Deities can customize the plane
558 table to disable marine missiles.
559 * Ridiculously impotent nukes could do unpredictable interdiction
560 damage. No such nukes exist in the stock game.
561 * The production command could mispredict resource-depleting level
562 production. No such products exist in the stock game. In fact,
563 they'd be highly unusual.
564 * The update could crash or corrupt the game when a (misconfigured)
565 product depleted resource "none".
566 * Revamp the Windows port based on ideas stolen from Gnulib. Share
567 the code between server and client.
568 * Don't log out player when update aborts a command under Windows.
569 Broken in 4.3.20, and not fully fixed in 4.3.21.
570 * Fix accepting connections from hosts with "long" IPv6 address. The
571 internal buffer had insufficient space.
572 * Delay shutdown up to 3s to let player output buffers drain.
573 * Fix a race between main thread and player threads, which could
574 theoretically make the server crash on start.
575 * Clean up synchronization between commands, update and shutdown, and
576 when player threads sleep on I/O.
577 * Clean up the cruft that has accumulated in and behind the empio
578 interface, and, to a lesser degree, the empthread interface.
579 * Fix time difference underflows in pthread and Windows code. They
580 could potentially cause hangs, although none have been observed.
581 * Make budget's "Sector building" line look better.
582 * Make sector maintenance cost configurable. New sect-chr selector
583 maint. Capitals now pay maintenance regardless of efficiency.
584 * Overhaul show sect b.
585 * Fix mine production resource limit for sector peffic != 100. This
586 affects mountains in the stock game, but only with an impractically
587 large number of ETUs per update.
588 * Code refactoring and cleanup.
589 * Info file fixes and improvements.
591 Changes to Empire 4.3.22 - Sat Apr 25 11:56:29 UTC 2009
592 * Fix a Windows client bug that could lead to hangs, at least with
593 some versions of the C run-time. Broken in 4.3.11.
594 * Allow building without curses terminfo. Highlighting in the client
596 * Really fix bomb not to wipe out plane updates made while it asked
597 for pinpoint targets. The fix in 4.3.21 didn't cover escorts.
598 * Fix tend land not to wipe out concurrent updates.
599 * Automatic supply fixes:
600 - Ships with just two shells could fire a torpedo to return fire or
602 - Ships with just one shell could use their anti-missile defense.
603 - Land units were considered in supply even when they had not quite
604 enough supplies. Such land units could defend without penalty,
607 * Fix update to take dead units off carriers.
608 * Standalone client distribution built empire instead of empire.exe
609 for Windows. Broken in 4.3.0.
610 * Fix client to abort script execution on SIGINT.
611 * Fix Windows client not to hang on EOF on standard input when that
613 * Fix a client bug that could make it hang when EOF on standard input
614 follows an execute command closely.
615 * Seamines under bridge spans were disabled a long time ago, in
616 Empire 2. The drop command refuses to mine there. Change mine
617 command to do so as well.
618 * Seamines under bridge spans were mistaken for landmines by ground
619 combat, land units retreating from bombs, and non-land unit ground
621 * When a bridge tower collapsed, its landmines magically became
623 * Don't log out player when he interrupts a command. Broken in
625 * Code cleanup and portability improvements.
626 * Info file and documentation fixes.
628 Changes to Empire 4.3.21 - Mon Mar 9 21:34:52 UTC 2009
629 * Fix swapsector not to wipe out concurrent changes to the swapped
631 * Fix a bug in crash dumping that could mess up the journal and, at
632 least in theory, mess up commands info, read, turn, and wire;
633 announcement expiry, and reading of econfig and schedule.
634 * Fix bomb not to wipe out plane updates made while it asked for
636 * When bombing ships with a force containing both planes with and
637 without capability ASW, the bomb command could fail to report
638 presence of submarines, and could refuse to bomb ships when there
639 were only submarines.
640 * Leaving land units behind after a victorious attack could in some
641 cases wipe out changes made to them since the victory.
642 * The timestamp selectors added to commodity, load and trade in
643 4.3.12 could lead to spurious command failures. None have been
644 observed in the wild.
645 * Don't log out player when update aborts a command. Broken in
647 * Code refactoring and cleanup.
649 Changes to Empire 4.3.20 - Fri Feb 20 18:14:20 UTC 2009
650 * Option LOANS is now disabled by default.
651 * Option RAILWAYS is now enabled by default.
652 * Many fixes to automatic supply:
653 - Planes flying interception or support missions, abms intercepting
654 ballistic missiles, and the launch command for missiles and
655 anti-sats could all supply more shells than necessary, lose
656 shells, or conjure them up.
657 - Ships shooting down marine missiles could supply more shells than
658 necessary, or lose shells.
659 - Supply ships could conjure up shells when firing guns using
660 multiple shells, or launching torpedoes, or dropping depth
661 charges, or shooting down marine missiles. No supply ships
662 capable of doing that exist in the stock game.
663 - Supply engineers could conjure up shells when laying mines. They
664 don't exist in the stock game.
665 - load, lload and supply could supply land units with enough food
666 from the sector containing them to starve the sector.
667 - Sectors were charged too much mobility for moving supplies
669 - Land units serving as supply source no longer draw supplies
670 recursively, because the bugs there are too hard to fix to be
672 - Defending and reacting units only checked whether they could draw
673 supplies, but didn't actually draw them.
674 - load, lload, supply, assault and board no longer supply land
675 units from ships carrying them. This feature, added in 4.0.14,
676 was inconsistent with other ways to supply.
677 - Don't use automatic supply to avoid starvation at the update. It
678 adds complexity to the update. How much good it does to players
679 is highly doubtful; certainly nobody can rely on it. It isn't
680 covered by the starvation command. Ships or land units could
681 steal enough food from their sector to make it starve.
682 - lmine could only fetch shells for engineers that use ammo. The
683 stock game's engineers all do.
684 The changes listed for load and lload are actually lies, because
685 supply has been disabled there since 4.3.17.
686 * Don't let an engineer lay mines while it is on a ship or land unit,
687 or in a foreign sector.
688 * Sectors and ships no longer need shells to fire flak.
689 * Use IPv4 and v6 only when suitable interfaces are configured.
690 * Fix turn off not to fail when the message is empty. Broken in
692 * Don't nag the deity about game hours restriction in force all the
694 * Tell deity when the game is down, just like players. Also make the
695 information available in xdump, as game selector down.
696 * Corrupt mailboxes could crash the server.
697 * Fix reject accept. Broken in 4.3.4.
698 * If a player was at a prompt when the deity turned the game down, he
699 was allowed to enter one more command.
700 * Air defense is no longer separate from interception. Putting a
701 plane on air defense now merely changes where it intercepts.
702 Separate air defense added too much pointless complexity. Its
703 implementation violated design assumptions of the intercept code.
704 Because of that, the same plane could intercept both an air defense
705 mission and the planes that triggered it, and the damage it
706 received in the first interception was wiped out.
707 * Intercept the same all along the flight path. In each sector, any
708 country owning the sector, a surface ship or a land unit there gets
709 to intercept. Before, only the sector owner got to intercept,
710 except for the assembly point and the target sector. In the target
711 sector, any country owning surface ships or land units got to
712 intercept in addition to the sector owner. Thus, a sector owner
713 with surface ships or land units there got to intercept twice. The
714 sector owner did not get to intercept at the assembly point,
715 even when it was the target sector.
716 * Spotting rule changes:
717 - Ships and land units now spot overflying planes along all of the
718 flight path instead of just the target sector, and no longer
719 report allied planes.
720 - Planes now spot ships and land units only when flying recon or
721 sweep, and along all of their flight path instead of just the
722 target sector. It still takes a spy plane to identify ships and
724 - Planes now spot ships and land units in a sector even when all
726 - Planes now spot all foreign ships and land units, not just
728 * Fix SAM interception for intercepts other than the first.
729 * Fix air defense and flak over sectors allied to the planes. Air
730 defense was broken in Empire 2. Flak was broken in 4.2.8.
731 * Establishing contact by spotting planes from sectors didn't work.
732 * Fix reconnaissance patrols to use sonar when any capable plane is
733 present. Before, all planes had to be capable.
734 * Fix recon and sweep not to spy after all spy planes are gone.
735 * Fix a bug that made multiple clients running on the same Windows
736 machine interfere with each other. Broken in 4.3.11.
737 * Fix enforcing game hours for players already logged in. Broken in
739 * Fix distribution not to abandon a distribution center by exporting
741 * Many fixes to load, unload, lload and lunload:
742 - Now usable for deities.
743 - Plug loopholes that let you steal foreign commodities by making
744 load/lload unload and unload/lunload load through use of negative
746 - Fix not to let you give away civilians.
747 - You can't use lload in foreign sectors or lunload with foreign
748 land units anymore. Loading stuff in foreign sectors was
749 prohibited already for ships.
750 - lload and lunload now work on foreign land units only when
751 they're explicitly named by uid. This matches behavior of load
753 - Fix to test relations of foreign object's owner to player instead
754 of the other way round.
755 * Make sure land units with maximum mobility can attack mountains.
756 * Fix land unit attack mobility cost. Broken in 4.3.6.
757 * Conditions comparing string-valued selectors like wing to unquoted
758 values are now interpreted more smartly. Before, unquoted strings
759 were prone to be interpreted as selector names even when that made
760 no sense. You still have to disambiguate truly ambiguous cases
761 like w=w for planes, e.g. as wing=w or w='w'.
762 * Fix reporting of shot spies in news. Broken in 4.3.16.
763 * Remove econfig key mission_mob_cost. Questionable feature, and
764 hasn't been used in a long time.
765 * Reserve and escort missions now have an op-area, like all the other
767 * Land units now react only when on a reserve mission. The lrange
768 command is gone. The edit command still accepts and ignores the
769 land unit key 'P' for compatibility, but it is deprecated.
770 * Fix a bug that could mess up mission op-area when the range of
771 ship, plane or land unit on the mission decreases, e.g. through the
773 * Reserve missions no longer give a bonus to reaction range.
775 * Code refactoring and cleanup.
777 Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
778 * LWP doesn't work with Darwin due to OS bugs, avoid it for now.
779 * Don't let ships double-retreat first on 'i' (injured) and then on
780 'h' (helpless) when shelled.
781 * Fix a bug that suppressed the "sunk!" message. Broken in 4.3.17.
782 * Log out player when maximum time per day is exceeded. Before, he
783 could remain logged in with visitor privileges only, but once
784 logged out could not log back in.
785 * If a player was at a prompt when either game hours restriction
786 started or maximum time per day was exceeded, he was allowed to
787 enter one more command.
788 * Deitying a capital failed to charge money and report news. Broken
790 * Overhaul accounting of play time, fixing minor inaccuracies.
791 * Fix parsing of 24:00 in econfig key game_hours and
793 * New option RAILWAYS.
794 * Che ages just like military reserves (1% per 24 ETUs).
795 * Permit ships to assault the sector they're in.
796 * Sectors eating less than one unit of food don't make one unit of
797 food for free anymore. They still can't starve.
798 * New concept sector terrain. Deities can use it to make sectors
799 other than wilderness redesignatable. See sect.config for more
801 * Represent play time in seconds rather than minutes. This affects
802 xdump: nat selector minused (counting minutes) is replaced by
803 timeused (counting seconds).
804 * Improved nightly build, with additional tests.
806 Changes to Empire 4.3.18 - Sat Oct 18 18:39:17 UTC 2008
807 * Fix building of planes, land units and nukes with uids that have
808 never been used before. This could crash the server on some
809 systems in certain states. Broken in 4.3.17.
810 * Improved nightly build, with restructured and extended tests.
812 Changes to Empire 4.3.17 - Sat Sep 20 16:07:44 UTC 2008
813 * Fix standalone client build for Windows. Broken in 4.3.11.
814 * Disable automatic supply of land units on load for now, it's
815 broken, and can be abused to duplicate supplies.
816 * Make trade show exactly what's on sale, remove option SHOWPLANE.
817 * Stop ships, planes, land units and nukes on violent takeover, just
819 * Wipe orders when ships, planes, land units and nukes are taken over
820 violently or given away peacefully. Fleet, wing, army and mission
821 were already cleared in many, but not all cases. Other orders were
822 never cleared: mission op-areas (visible in xdump), ship autonav
823 orders, ship sail path (including ship to follow and mobility
824 quota), land unit retreat orders, plane range limit, and land unit
826 * Fix takeover of stuff by attack, assault, board, lboard, paradrop
828 - Corrupt land unit file could lead to infinite recursion.
829 - Take over nuke armed on plane along with the plane. Broken in
831 - Taking over land units with negative mobility increased mobility
832 to zero. Ditto for planes embarked on ships or land units.
833 * Fix a bug that made set and xdump not recognize unused trade lots
835 * Fix giving away stuff by trading it:
836 - When an armed nuke is sold separately from its plane, take it off
837 the plane. You couldn't do that before 4.3.3.
838 - Give away nuke armed on sold plane along with the plane. Broken
840 - Don't zero mobility of planes and land units on sold ships.
841 * Fix giving away stuff by unloading from its carrier: Give away any
842 nukes armed on planes (broken in 4.3.3) and land units loaded on
843 land units. The latter can't happen in the stock game.
844 * Fix giving away stuff by scrapping or scuttling its carrier:
846 - Disarm the nuke from a plane instead of destroying it.
847 - Give away any loaded land units and planes, too.
849 - Fix scuttle to ask for confirmation when scuttling a tradeship in
850 an unsuitable sector even when the tradeship is pirated. Broken
852 - Fix scuttle to require 2% harbor efficiency for a trade ship to
853 pay. Also require at least friendly relations.
854 - Make autonav refuse scuttle orders in unsuitable sectors.
855 * Clean up rules on where you can scrap stuff:
856 - Ships in own or friendly, efficient harbors (relations used not
857 to matter, contrary to info)
858 - Planes in own or allied, efficient airfields (friendly used to
859 work as well, contrary to info)
860 - Land units in any own or allied sector (relations used not to
861 matter, and you couldn't scrap them on ships)
862 Also tell player why something can't be scrapped instead of
863 ignoring it silently.
864 * Rewrite the broken code to move land units, planes and nukes along
865 with their carrier. The old code was a hack that didn't update
866 timestamps (so incremental dumps didn't pick up the movement), and
867 it didn't cover all uses. The update, in particular, was prone to
868 see cargo in old locations, which could screw up repairs.
869 * Expire lost items at the update instead of continuously.
870 * Replace econfig key lost_items_timeout by lost_keep_hours.
871 * Minor Windows threading fixes.
872 * Journal now uses human-readable names to identify threads.
873 * Ship and land unit load counters are no longer stored in game
874 state, because they duplicate information already there. Same for
875 the type of nuke loaded on a plane. Remove field nuketype from
876 xdump plane. Clients can simply find the plane's nuke instead.
877 The edit command still accepts and ignores the plane key 'n' for
878 compatibility, but it is deprecated.
879 * Ship and land unit load counts as displayed by ship, sdump, land,
880 ldump, ship selectors nplane, nxlight, nchoppers, nland, and land
881 selectors nxlight, nland are now reliable. They used to get out of
883 * Ship load counts now reflect what is loaded, not how it is stored.
884 For instance, if a light carrier, capable of carrying 4 x-lights
885 and 20 light planes carries nothing but 5 sams, we now have
886 nxlight=5, nplane=0 instead of nxlight=4, nplane=1.
887 * New cargo lists data structure to let code find loaded planes, land
888 units and nukes easily and efficiently.
889 * Revamped upkeep of lost file. It should be reliable now.
890 * Disable the ill-advised error recovery on sector access that swept
891 bugs under the carpet rather than recovering from them.
892 * Occupied sectors no longer revert to the old owner when all
893 military and land units go away. This feature was added in
894 Chainsaw 3. It wasn't integrated properly with the che code
895 (things went wrong when che killed all defenders, but couldn't
896 convert the sector due to its loyalty), and combat code (if an
897 attack killed off all local defenders and got defeated by reacting
898 units, the sector changed ownership anyway, silently).
899 * Include destination coordinates in interception and plane mission
901 * Client could misdiagnose redirections and executes as unauthorized,
902 or die outright. Broken in 4.3.11.
903 * Fix xdump realm to dump player instead of absolute coordinates.
904 Disclosed the true origin. Broken in 4.3.0.
905 * Fix spy to reliably avoid spying same sector more than once.
906 * The map drawing code could smash the heap when the world was
908 * When a satellite's launch trajectory was off, its coordinates could
909 get screwed up, which made it invisible in skywatch.
910 * Fix several bugs that made the path command screw up when the path
912 * Fix the default size of the map shown by move, test and transport
914 * Fix bugs that could make arguments in area or dist syntax miss
915 ships, planes, land units and nukes at the border of the selected
916 area, if that area spans the whole world. In sufficiently small
917 worlds, it could also make radar miss satellites and ships, sonar
918 miss ships, satellite miss ships and land units, nuclear
919 detonations miss ships, planes, land units and nukes, automatic
920 supply miss ship and land unit supply sources, ships and land units
921 fail to return fire, ships fail to fire support.
922 * Maps sometimes showed x-coordinates as three lines instead of two
924 * Improved nightly build, tests in particular.
925 * Code refactoring and cleanup.
927 Changes to Empire 4.3.16 - Sat Aug 9 15:56:52 UTC 2008
928 * Production command incorrectly limited the number of graduates,
929 happy strollers, technological breakthroughs and medical
930 discoveries produced by a sector to 999. Broken in 4.2.15.
931 * Fix a bug in improve that could let you spend more money than you
933 * Fix work command not to spend more mobility than requested, and to
934 round mobility use randomly instead of down.
935 * Commands demobilize, convert and work no longer let you spend more
936 money than you have. Commands demobilize and convert no longer ask
937 for confirmation before spending more than half your money. Saving
938 that feature would have been more work than it's worth.
939 * Remove undocumented key 'd' at bomb ship, plane and land unit
941 * Fix land unit flak when pin-bombed to match flak when overflown:
942 proportional to efficiency, and randomly rounded. Was missed in
944 * Don't permit bombing of embarked planes and land units.
945 * Fix capital maintenance to charge at 60% efficiency.
946 * launch command now requires only 40% plane efficiency, for
947 consistency with other ways to launch missiles.
948 * Disable collateral damage when automatically launched missiles miss
949 their target. Collateral damage was done even when the launch
950 failed or the missile got intercepted. It's been disabled for
951 manually launched missiles since 4.0.18, for the same reason.
952 * Fix a bug that corrupted the lostitems file. Broken in 4.3.12.
953 * Show command changes:
954 - Move product information from "show sect c" into new "show
955 product", and reformat it to be easier to understand.
956 - New column navigability in "show sect s".
957 - "show sect s" now shows the packing bonus type instead of
958 selected packing bonuses. "show item" shows the actual bonuses
960 - "show sect b" now shows the usual values in addition to unusual
962 * Fix interdiction to obey op-area for missiles.
963 * Fix a bug that caused a stale sources.mk to be distributed in the
964 4.3.14 an 4.3.15 tarballs. The latter does not build out of the
966 * Don't strip tab characters from quoted command arguments. Broken
968 * shutdown commands now always take effect immediately. Before, they
969 could be delayed by up to a minute.
970 * shutdown could start multiple shutdown threads when you initiated a
971 shutdown shortly after cancelling one. This screwed up the timing
973 * Deity syntax of zdone changed, and is now documented in info.
974 * The threshold command could be tricked into accepting negative
976 * Fix designate to always write updated bmap to disk.
977 * Fix bomb to fail on empty <pin|strat> argument instead of flying
979 * Fix a bug in distribute that screwed up the current sector's
980 distribution center when the command got aborted.
981 * Commands arm, bomb, deliver, drop, fire, fly, paradrop, recon,
982 lmine, order, power, range, sail, shutdown, sweep and tend did not
983 honor command abortion at some prompts.
984 * Fix a bug in handling of EOF from client that could bite in the
986 - EOF at target prompts for bombing commodities, ships, planes and
987 land units sent the server into an infinite loop that ate all
989 - EOF at sail's path prompt crashed the server.
990 - EOF at some prompts in deliver, designate, fly, morale, zdone,
991 attack and assault didn't abort the command.
993 * Selector terr is now the same as terr0 for mortal players, and
994 dterr for deities. This matches how the territory command works.
995 Unfortunately, this required us to rename xdump sect field terr to
996 terr0. Sorry about that.
997 * Fix bomb not to let you bomb dead ships and land units.
998 * Make the retreat command a bit more helpful on retreat conditions,
999 and make it fail on bad conditions.
1000 * Fix the mapper scripts. Broken in 4.2.0.
1001 * Fix flying commands not to let planes do double duty as escorts.
1003 * When a minesweeper hit a mine after sweeping, the mine wasn't used
1004 up. If it sank the minesweeper, the code accessed freed memory,
1005 which could clobber the ship file or worse. Broken in 4.0.17.
1006 * Don't let non-light units board ships that can't carry them.
1007 * Capitals can now employ up to 1000 civilians instead of 999.
1008 * Spy command changes:
1009 - Spy now requires sector military. Before, presence of land units
1010 was sufficient, but spies shot were only deduced from sector
1011 military. If you lost more spies than you had sector military,
1012 the rest came back from the dead.
1013 - Spy no longer ignores non-sea sectors without civilians, military
1015 - Remove columns lnd, pln from spy report. The values didn't match
1016 the reported land units and planes, and could leak the presence
1018 - Establish contact when spy succeeds even though the spy was
1020 * Fix news reporting and damage when land units interdict ships in
1021 sectors other than sea.
1022 * Fix land unit return fire damage to ships to take accuracy into
1023 account, like the fire command and interdiction does.
1024 * Remove the inconsistent shelling damage reduction for range. Fire
1025 command got damage reduced by 10-20% with a chance depending on
1026 range ("Wind deflects shells"). Ships interdicting got it reduced
1027 by half. Other ways to shell did not get damage reduced for range.
1028 * Fix ground combat to report defending land units. Broken in 4.3.4.
1029 * Info file and documentation fixes and improvements.
1031 Changes to Empire 4.3.15 - Sun May 18 08:59:30 UTC 2008
1032 * The edit command keys deprecated in 4.3.10 are now gone.
1033 * fairland now obeys game file locks.
1034 * Do not leak world creation time in files utility, because that
1035 facilitates attacks against fairland's PRNG. Broken in 4.3.12.
1036 * Fix starvation not to starve one more than it should. The last man
1037 on a boat or land unit now can't starve anymore.
1038 * Fix a crash bug in satellite. Broken in 4.2.7 and not fixed
1039 correctly in 4.2.12.
1040 * Fix a coordinate normalization bug that could theoretically lead to
1041 buffer overruns and other unpleasantness. None have been
1042 reproduced, though. Broken in 4.3.12.
1043 * Remove option FUEL. The abstract idea of tying ships and land
1044 units to a logistical tether is sound, the concrete implementation
1045 as option FUEL is flawed. It adds too much busy-work to the game
1046 to be enjoyable. It hasn't been enabled in a public game for
1047 years. The code implementing it is ugly, repetitive, and a burden
1048 to maintain. The edit command still accepts and ignores the fuel
1049 keys for compatibility, but they are deprecated.
1050 * Fix pin-bomb not to report subs when there are none.
1051 * You now have to take a capital to capture the victim's money, loans
1052 or market lots. Merely obliterating the capital doesn't cut it.
1053 It still makes the victim lose money, though.
1054 * Fix a bug that could theoretically allow sacking of non-existant
1055 capitals of visitors, deities and such.
1056 * You now gain BTUs and MOB_ACCESS mobility before the first update
1057 again. You didn't since 4.3.10 introduced the ETU clock.
1058 * Fix edit to detect when the edited object changes while it's being
1060 * Fix xdump nat for relations: it got HIDDEN backwards. Broken in
1062 * Fix origin command not to prompt twice for its argument. Broken in
1064 * Info file improvements.
1066 Changes to Empire 4.3.14 - Mon May 5 04:57:03 UTC 2008
1067 * Another round of fixes to the fire command:
1068 - Don't disclose where the target retreated to.
1069 - Charge the target shells for returning fire.
1070 - Always use guns when the target is out of range, even if it's a
1071 submarine. Before, the difference in shell use disclosed whether
1072 the target is a submarine. Loophole opened in 4.3.12.
1073 - Make depth charges again work with just one shell. Failing the
1074 command in that case lets players find out whether the target is
1075 a submarine. Loophole opened in 4.3.12.
1076 - Detect when the firing sector, ship or land unit changes across
1077 the target prompt. Can be abused to duplicate commodities, and
1079 * Fix parsing of anchor-relative time in update schedule. Broken in
1081 * Fix logging of player input in the journal to include command
1082 interruption and EOF.
1083 * Fix oversights in 4.3.12's change to keep track of flying planes:
1084 planes could be erroneously reported damaged by their own ground
1085 strikes. Happened with missions and the launch command.
1086 * Fix load not load hardened missiles.
1087 * Fix harden not to harden missiles loaded on land units.
1088 * New server option -E to choose what to do on recoverable internal
1089 error. You can now make the server dump core and keep going (not
1090 implemented for Windows). New econfig key post_crash_dump_hook to
1091 run a program after crash-dumping. See scripts/savecore for an
1093 * Journal entries are now flushed to disk right away even when the
1094 server is not running in debug mode.
1095 * Don't let land units load trains.
1096 * Allow deity to display power report for all types of countries,
1098 * Fix designate's check for disallowed sector types. Broken in
1100 * Documentation fixes.
1102 Changes to Empire 4.3.13 - Tue Apr 15 19:03:11 UTC 2008
1103 * Work around strptime() lossage on some systems. Fixes the parsing
1104 of the schedule file there.
1105 * New selector maxnoc for xdump version.
1106 * Fix initialization of realms in newcap. Broken in 4.3.12.
1107 * Fix add for status arguments active, god, delete. Broken in
1109 * Info file, manual page and documentation fixes.
1111 Changes to Empire 4.3.12 - Wed Apr 2 05:35:06 UTC 2008
1112 * Fix rounding error in update that could result in more babies than
1113 food permits, and negative food.
1114 * Fix a bug that could lead to unfair thread scheduling under
1116 * Fix ship and land unit missile interdiction and ballistic missile
1117 interception to require a proper base. Before, missiles could
1118 launch from anywhere for that.
1120 - Don't allow launching from unowned sectors.
1121 - Don't destroy missiles stuck on foreign ships.
1122 - Use up the supplies required for launching an asat only when it
1124 - Don't ignore satellites' fuel use.
1125 * Deity command newcap now requires its second argument (sanctuary
1126 coordinates). Before, it tried to pick a suitable location when
1127 none was given. The code implementing this feature had problems,
1128 and it's not worth fixing, because it is obscure, and rarely (if
1129 ever) used: no conscientious deity would use it for a real game,
1130 and for blitzes fairland does a better job.
1131 * Keep track of flying planes properly. This fixes a number of bugs:
1132 - While the bomb command awaited pin-bombing target input from the
1133 player, other players could interact with the pin-bombers and
1134 escorts as if they were sitting in their bases: spy them, damage,
1135 capture, load, unload, or upgrade them, even get intercepted by
1136 them. But any changes to those planes were wiped out when they
1138 - The bomb command could bomb its own escorts, directly (pin-bomb
1139 planes) or through collateral damage, strategic sector damage,
1140 collapsing bridges or nuke damage. The damage to the escorts was
1141 wiped out when they landed.
1142 - If you asked for a plane to fly both in the primary mission and
1143 escort, you got charged fuel for two sorties instead of one.
1144 * Plug memory leaks in plane interception.
1145 * Fix trade not to let the buyer teleport satellites (not in orbit)
1146 and asats to an arbitrary sector. Abusable, because abms
1147 intercepted from anywhere, and satellites could be launched from
1149 * The PRNG seed is now logged in the journal.
1150 * Fix nightly build for Windows.
1151 * Fix crash bug that bit when custom tables contained columns names
1152 that existed, but weren't supposed to be in the custom table.
1153 * New timestamp selector for commodity, country, game, loan, nation,
1154 news, realm, trade, treaty to support incremental xdump.
1155 * Deity commands newcap and add wipe the nation more thoroughly. add
1156 no longer touches relations and flags for status active and god.
1157 * New utility program empdump to export and import game state as
1158 plain text. Check its manual for details, including limitations.
1159 * Plane, ship and land unit stats are no longer stored as game state,
1160 but recomputed from tech and base stats as needed.
1161 * xdump ver is no longer a special case. Syntax "xdump ver" is now
1162 deprecated. Use "xdump version *".
1163 * Fire and torpedo cleanup and bug hunt:
1164 - Plug memory leak in fire command.
1165 - Fix ammunition use when returning fire: resupply could lose
1166 shells when returning fire to multiple targets, and land units
1167 were charged per target instead of just once.
1168 - Interdicting land units now resupply shells automatically, for
1169 consistency with other ways to fire.
1170 - torpedo and fire no longer resupply shells automatically. The
1171 latter used to resupply land units only.
1172 - Land units no longer have to be in supply to fire actively, for
1173 consistency with other ways to fire.
1174 - Submarines with zero mobility can no longer interdict, for
1175 consistency with other ways to torpedo.
1176 - Fix bugs that let submarines without capability torp use
1177 torpedoes to return fire and interdict.
1178 - Fix torpedo command not to require a line of sight for return
1179 fire and depth charges, and to use torpedo range instead of
1180 firing range for return torpedoes.
1181 - Active fire and interdiction didn't work for ships with zero
1182 firing range, even though return fire and support did. No such
1183 ships exist in the stock game.
1184 - Let land units with zero firing range and non-zero firing damage
1185 fire, for consistency with ships. No such units exist in the
1187 - Ships required different numbers of military to operate their
1188 guns for the various kinds of fire. Unify to require 2*N-1
1189 military to fire N guns.
1190 - Ship ammunition use differed for the various kinds of fire.
1191 Unify to use one shell per two guns.
1192 - Forts could fire support even when there were not enough mil.
1193 - Fix automatic shell resupply in several places to supply exactly
1194 the shells actually fired, no more, no less.
1195 * Change depth charges back to how they are documented and worked
1196 before 4.0.6, mostly: require no guns, one military, do damage like
1197 shell fire from three guns (before 4.0.6: two guns), use two
1198 shells. In 4.0.6's model, they worked exactly like shell fire
1199 (require guns and gun crew, non-zero firing range, damage and
1200 ammunition use scales with available guns), except for missions,
1201 which was a bug. Note that depth charge damage for all ships is
1202 now like fire from three guns for two shells. No change for dd; af
1203 did two gun damage for one shell before, and nas did four gun
1204 damage for two shells.
1205 * The edit command keys deprecated in 4.3.3 are now gone.
1206 * Fix build not to screw up automatic dependencies on certain compile
1208 * Fix a bug that could prevent repeated news from properly
1209 aggregating into one news item.
1210 * Properly initialize all bits in game state files, even those that
1212 * Fix explore's test for stopping on a splashed bridge. The bug made
1213 explore print to a bogus message.
1214 * Fix spelling of symbol airburst in table plane-flags. This could
1216 * Change designate not to check total cost before executing the
1217 redesignation. The code implementing that was buggy and too ugly
1218 to live. Designate doesn't cost anything in the stock game.
1219 * Always charge land units at least as much mobility for assaulting
1220 from non-landing ships as from landing ships. Before, marines lost
1221 all mobility when assaulting from a non-landing ship, which could
1222 be less than what the same assault costs from a landing ship (half
1224 * Fix LWP's stack initialization for -s. It caused crashes on some
1226 * Fix confused and buggy bridge splashing code:
1227 - Flying planes could be reported drowned.
1228 - Pin-bombing a bridge head failed to collapse bridge spans for
1229 lack of support, unless the pin-bombing caused collateral damage.
1230 - Corrupt sector file could lead to infinite recursion.
1231 * Relative names now work for econfig keys data and info.
1232 * Fix utility programs to abort on internal errors. They used to
1233 print a message and attempt to recover.
1234 * Fix off-by-one in fairland that ate the last expansion island.
1235 * Switch from CVS to git.
1236 * Code refactoring and cleanup.
1237 * Portability fixes.
1238 * Info file, manual page and documentation fixes and updates.
1240 Changes to Empire 4.3.11 - Tue Jan 1 18:57:38 UTC 2008
1241 * New sector selector elev. It's set by fairland, but has no effect
1242 on the game. It can be useful for deities to customize a world
1243 created by fairland.
1244 * The client now copes with ids greater than 15. The Empire
1245 protocol currently uses 14 ids.
1246 * Rewrite the client's code for reading server output during login.
1247 The old code could write one byte beyond the end of the buffer
1248 (theoretically a remote hole), got confused by long lines, and
1249 lines that didn't arrive in one piece.
1250 * Long country name, password or user name crashed the client.
1251 * Fix xdump not to deny access to game state tables when maximum
1252 minutes per day are exceeded.
1253 * The server considers a country bankrupt when its treasury is
1254 negative. Except when it doesn't. Fix that:
1255 - report misreported countries with $0 as broke.
1256 - If a command spent a few cents more than you had, commands requiring
1257 money became unavailable even when rounding brought you back to
1258 $0. But logging out and back in then bankrupted you.
1259 - If your treasury rose to exactly $0, commands requiring money
1260 remained unavailable.
1261 - If you had $0, sectors didn't build and sectors and ships didn't
1262 produce at the update.
1263 * Fix a bug in trade that made your money evaporate when a trade fell
1264 through because you couldn't fully pay. This bug was there since
1265 the introduction of the market in 4.0.0. It got aggravated by the
1266 removal of forced loans in 4.3.0.
1267 * Fix printing of the new group in army, fleet and wing. Broken in
1269 * Fix flash not to screw up the message when the first argument
1270 contains white-space.
1271 * Don't let planes intercept when they are stuck in foreign bases, on
1272 inefficient ships or land units, or on land units loaded on ships
1274 * Fix a bug that made interception require petrol to be present even
1275 for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
1276 defense missions weren't affected.
1277 * fairland and setsector now limit fertility to 100 instead of 120,
1278 like the other resources.
1279 * Generalize the autonav hack for fishing boats so it covers oil
1281 * Fix bug in path command that made it swallow every other step.
1283 * The execute command no longer supports redirections and execute in
1284 batch files. Flaws in the Empire protocol make it next to
1285 impossible for clients to implement that correctly. See
1286 doc/clients-howto for an explanation.
1287 * Rewrite much of the client's code for sending commands and
1288 receiving server output:
1289 - No longer blocks on sending commands, which could deadlock the
1291 - Fix race condition that could cause server output to be discarded
1292 on EOF on standard input.
1293 - Don't discard server output when reading standard input fails.
1294 - Fix error handling for execute and other, more obscure cases.
1295 - More rigorous error checking for redirections and execute.
1296 Clearer error messages, too.
1297 - Fix execute redirected to file or pipe. Believed to be broken in
1299 - The client now creates files for redirections with the same
1300 permissions whether the redirection is in a pipe or not. Before,
1301 redirections without a pipe created files with no permissions for
1302 group and others. This change may make your redirected output
1303 visible to other users on your system. Use the usual controls,
1304 like umask, to restrict permissions to your liking.
1305 - Reject unexpected redirections (violating the protocol). Before,
1306 they silently replaced the current one, and in the case of pipes
1307 leaked file descriptors and memory.
1308 - Redirections in batch files are not implemented. They didn't
1309 quite work before, and could leak memory and file descriptors. A
1310 flaw in the Empire protocol makes them next to impossible to
1311 implement correctly.
1312 - The execute command in batch files is not implemented. A flaw in
1313 the Empire protocol makes this practically useless anyway.
1314 - Old code leaked memory in various places.
1315 - Unfortunate incompatibility with older servers: if you type the
1316 EOF character (normally ^D) at an argument prompt, the session
1317 hangs. Use the interrupt character (normally ^C) to get out.
1318 * The client now supports options -h and -v.
1319 * The client no longer zaps its command line in a lame attempt at
1320 protecting users who foolishly specify passwords on the command
1321 line. Zapping annoys system administrators and creates a false
1323 * Journal entries are now flushed to disk right away when the server
1324 is running in debug mode.
1325 * Fix bugs in load that could make loading operations fail noisily
1326 instead of silently on some systems.
1327 * Server now reliably shuts down session when it receives an
1328 end-of-file condition from the client. Before, it merely failed
1329 the current command when it got it at an argument prompt.
1330 * Fix bug in execute that could crash the server on some systems when
1331 it prompts for the argument.
1332 * Fix bug that let you check whether a non-allied carrier is
1333 efficient enough for takeoff when one of your planes got stuck
1335 * Fix bug that let you attempt to escort a one-way mission to a
1336 carrier with non-light, non-interceptor escorts. Such planes don't
1337 fit on carriers, and the command then failed with a bogus error
1338 message. Before 4.2.17, the planes flew, and the escorts were
1340 * Change the rules for fitting planes on ships slightly, so that the
1341 order of loading no longer matters. Choppers and x-lights can now
1342 use plane slots even when not light. X-light choppers, which don't
1343 exist in the stock game, can no longer use x-light slots.
1344 * The server now keeps its log file open, just like the journal.
1345 * New server option -R to set the PRNG seed. This is for
1346 reproducible tests. Change the Windows-only service uninstall
1347 options from -r/-R to -u/-U.
1348 * Supply a real PRNG for Windows instead of the leaky water-pistol
1350 * Threads sleeping until a specified time could return early under
1351 Windows. This could cause missed updates. Broken in 4.3.10.
1352 * Fix missing newline in show updates.
1353 * Power report didn't factor tech into power correctly. Broken in
1355 * Code refactoring and cleanup.
1356 * Info file and documentation fixes and updates.
1358 Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
1359 * Bridge spans now cost $1000 instead of $2000, and bridge towers
1360 $3000 instead of $7500.
1361 * The Windows port now supports IPv6, but it still needs to be
1362 enabled manually at compile-time.
1363 * The custom table reader detects more errors.
1364 * Do not leak world creation time in files and fairland, because
1365 that facilitates attacks against the PRNG. This misfeature crept
1367 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
1368 Using it required manual hackery since 4.3.0.
1369 * Plug file descriptor leak in add command.
1370 * Don't kill player connections violently when their thread appears
1371 to be hung. Threads being aborted by update or shutdown could be
1372 misidentified as hung, and the violence could lead to resource
1373 leaks, locked out updates, and corrupted game state.
1374 * Fix LWP to reliably wake up threads sleeping for a time. Before,
1375 players with a sufficiently fast connection could starve out system
1376 threads, including the update.
1377 * Fix a class of bugs that made commands behave differently while the
1378 update is attempting to take control:
1379 - No MOB_ACCESS mobility was gained.
1380 - Telegrams were miscounted.
1381 - Bulletins got misfiled as production reports.
1382 - The navigate command ignored sail paths.
1383 - The declare command was more quiet, and declarations of war
1384 failed silently when SLOW_WAR was enabled.
1385 - Many messages got misdirected to bulletins.
1386 Some of these bugs go back all the way to Empire 2, ca 1995.
1387 * New deity command reload, effect similar to SIGHUP.
1388 * Not voting for a demand update no longer lets you veto further
1389 demand updates. This feature was flawed (it encourages players to
1390 vote late so that they can tactically vote no and thus build up
1391 veto rights), virtually unused, and buggy. The edit command still
1392 accepts and ignores the country key 'U' for compatibility, but it
1394 * Fix zdone not to claim to have triggered an update when they're
1396 * New update scheduler and ETU clock:
1397 - New schedule file. See doc/schedule for how to use it. Replaces
1398 econfig keys update_policy, adj_update, update_times, hourslop,
1399 blitz_time. A change of schedule does not require a server
1401 - The force command can no longer force updates in the future.
1402 Edit the schedule file for that.
1403 - New command show updates to show the update schedule. Obsoletes
1405 - New xdump game and xdump updates.
1406 - New utility program empsched to help test update schedules.
1407 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
1408 by econfig key update_demand.
1409 - econfig key update_demandtimes no longer applies to scheduled
1411 - You now receive new BTUs at the update in addition to login.
1412 - You now always gain the same BTUs and MOB_ACCESS mobility per
1413 turn, even when the update schedule changes, updates get missed,
1414 or unscheduled demand updates run.
1415 - Remove the mobupdate command, because porting it to the new ETU
1416 clock is not worth it.
1417 * Redesign of synchronization between commands, update and shutdown,
1418 and how updates are triggered:
1419 - Simplify update to a single thread waiting for the trigger.
1420 Before, three update threads had to perform a carefully
1421 choreographed dance to make updates happen. The dance relied on
1422 thread priorities for correctness, which are only implemented by
1423 LWP. With pthreads and under Windows, demand updates were prone
1424 to two update threads starting up concurrently. Even with LWP,
1425 forced and demand updates could lead to double updates.
1426 - Use a lock for synchronization: commands take it shared, update
1427 and shutdown take it exclusive. This makes update and shutdown
1428 block until all aborted commands terminated and gave up their
1429 lock. Before, they proceeded blindly after waiting two or one
1430 seconds respectively, which was cheesy and unsafe.
1431 - New commands no longer fail while the update is pending, they are
1432 delayed until after the update.
1433 - New commands can no longer start during shutdown. Before, they
1434 could, but risked getting killed violently, possibly corrupting
1436 - Fix command execution so that commands blocked in writing
1437 redirections are abortable. The bug allowed players to delay
1438 update and shutdown indefinitely.
1439 - Fix shutdown not to let player threads block on output. This
1440 let players delay shutdown indefinitely.
1441 - Fix reading of player input not to block again after update or
1442 shutdown aborted it. The bug allowed players to delay update and
1443 shutdown indefinitely.
1444 * Thread priorities are only implemented by LWP and no longer used.
1445 With LWP, they let players with a sufficiently fast connection
1446 starve out the threads that clean the lost file and kill idle
1447 connections. Drop them.
1448 * Show nuke rounded required research incorrectly.
1449 * Log unprintable characters as octal escapes rather than question
1450 marks in the journal file.
1451 * The files program no longer changes permissions of existing files.
1452 * The files program now creates all files with permissions ug=rw and
1453 all directories ug=rwx, modified by umask.
1454 * Fix a bug that could make arm, disarm and nuke detonation work with
1455 a used-up nuke instead of the armed one. This could be abused to
1456 detonate nukes multiple times. Broken in 4.3.3.
1457 * Fix nuke detonation output for zero blast radius.
1458 * Plug memory leaks in thread code.
1459 * Fix a bug that made LWP I/O wakeup unreliable.
1460 * New march sub-command v for view.
1461 * Journal was initialized before threads were, which was wrong.
1462 * Fix server not to create a journal on SIGHUP when it is disabled.
1463 * shutdown 0 now requests immediate shutdown instead of cancellation
1464 of a pending shutdown. shutdown -1 now cancels.
1465 * flash and wall no longer split long message lines.
1466 * Fix a bug in collect that screwed up a fully collected loan instead
1467 of deleting it. The screwed up loan could not be sharked or
1468 collected, but it could be repaid.
1469 * Remove the wait command, it's been broken and restricted to deity
1470 since Empire 2, ca. 1995.
1471 * Budget failed to take sector production into account for predicting
1472 unit repairs. Before 4.3.6, this bug bit only when you fooled
1473 around with budget priorities.
1474 * When unit repairs are limited by materials, the efficiency gain is
1476 * Ship repairs outside harbors and plane repairs by carriers used to
1477 consume commodities when and as far as available. Now, they
1478 consume the same fraction of the real cost of each commodity,
1479 i.e. commodity use is limited by the most scarce commodity.
1480 Neither old nor new behavior make much sense, but the new code is
1482 * Code refactoring and cleanup, in particular to make the Windows
1484 * Portability fixes.
1485 * Info file and manual page updates. All manual pages are now
1486 installed in section 6.
1488 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
1489 * Fix declare to prevent the deity from changing relations for a
1490 player to self. Allow the deity to set the relations of a player
1492 * Fix arm not to put the same nuke on multiple planes (broken in
1494 * New option AUTO_POWER.
1495 * Sectors now repair allied land units.
1496 * Sectors now repair only own and allied planes.
1497 * Fix repair of planes on foreign carriers: repair allied planes,
1498 ignore the others. Before 4.3.3, carriers destroyed rather than
1499 repaired foreign planes. Since 4.3.3, foreign planes were treated
1500 as recoverable error.
1501 * Fix automatic fortification of land units to use all excess
1502 mobility even when mobility delta exceeds mobility maximum.
1503 * Disable automatic fortification of land units when MOB_ACCESS is
1504 on, because it is prohibitively slow then (broken in 4.2.13).
1505 * Budget now shows level production (tech, education, research and
1506 happiness) rounded instead of randomly rounded.
1507 * Fix update not to randomly flush small level production to zero.
1508 * Fix overly restrictive game file locking under Windows (broken in
1510 * Fix navigate to charge mobility for sweeping mines without moving
1514 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
1515 * Ships no longer produce stuff when the government is broke.
1516 * Fix land unit casualties in revolts.
1517 * Fix security units not to raid friendly che.
1518 * Fix update sequence to ensure stopped sectors don't work on the
1519 ships, planes and land units in the sector. Before 4.3.6, this bug
1520 bit only when you fooled around with budget priorities.
1521 * Fix canal loading (was broken in 4.3.0).
1522 * Fix tend not to tend land units that could not be loaded.
1523 * Make xdump command available before break, but deny access to game
1525 * Lock game files to prevent concurrent access by multiple programs.
1526 fairland does not yet obey the lock.
1527 * Fix production to consider sector item limit.
1528 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
1529 * Enhanced mapping sub-commands in move, test, explore and transport.
1533 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
1534 * Sanctuaries are again fully populated with civilians (4.3.6 changed
1535 the limit, but not the population). Food is now spread evenly
1537 * Fix path finder to find shortest naval and aerial paths again
1539 * transport's map sub-command now does the right thing for a unit
1541 * Fix bug in map sub-command of move, explore and transport that
1542 passed junk to map command. Could theoretically crash.
1543 * Food need reported by starvation was one short for sectors without
1545 * Change land unit ammunition use back to what it was before 4.2.3.
1546 This lets deities customize ammunition use independent of damage.
1547 It also substantially reduces ammunition consumption at high tech.
1548 * navigation and march enhancements:
1549 - Sub-command 'f' now takes an optional ship / land unit number.
1550 - Mapping sub-commands now take an optional ship / land unit
1552 - New sub-command 'd' to drop mines.
1553 * Let minesweepers retreat at their full speed (missed in 4.3.6).
1554 * SUPER_BARS cannot be harmed, so don't interdict them.
1555 * Don't let trains and non-trains march together for now, because the
1556 march code isn't prepared for that.
1557 * New mapping flag 'n' to show nukes.
1558 * Mapping flag '*' now shows nukes as well.
1559 * New command nbmap to bmap around a nuke. Overload command nmap to
1560 map around a nuke when given a nuke argument.
1561 * Fix an inconsistency that gave tactical bombers a small bonus
1562 vs. flak when pin-bombing.
1563 * Fix production to show the designation that actually produces, not
1564 the designation as it is now (broken in 4.3.6).
1565 * Fix accidental whitespace change in output of sdump, pdump and
1566 ldump that crept into 4.3.5.
1567 * Support user-defined sector types and products in custom tables,
1568 not just customization of existing ones.
1569 * Fix off-by-one bug in budget that used to be masked by budget
1570 priorities until their demise in 4.3.6. The bug could crash the
1571 game on certain systems.
1575 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
1576 * The shutdown command now terminates the server process correctly
1577 even with LinuxThreads pthreads under Linux 2.4 and earlier.
1578 * Cope with old versions of groff (broken in 4.3.0).
1579 * You can now arm allied planes with nukes.
1580 * Taking a nuke off a plane gives it to the sector owner again.
1581 Feature was accidentally dropped in 4.3.3. Recipient must be
1583 * Naval path went bananas for impassable end sectors (broken in
1585 * New econfig key disabled_commands.
1586 * New territory selector dterr, restricted to deities. The territory
1587 command defaults to it for deities.
1588 * Let land units attack as long as they have positive mobility,
1589 except for high-mobility terrain (mountains), where the rules
1590 remain as they were: land units need to have all the mobility
1591 charged for the attack, not counting combat and moving in to
1592 occupy. Rationale: Making sure your land units reach attack
1593 positions with enough mobility left is a pain in the neck.
1594 Requiring only positive mobility is friendlier, but allowed rushing
1595 of mountains, so we make an exception there.
1596 * Can typeset info pages as PostScript. Result isn't exactly pretty.
1597 * Support disabling of infrastructure in infra custom table. Remove
1598 redundant option DEFENSE_INFRA. show command now shows only enabled
1600 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
1601 pmap sbmap, smap (broken in 4.3.1).
1602 * New, simpler sector mobility cost formula:
1603 - The basic cost is still a linear function of sector efficiency,
1604 with customizable cost at 0% and at 100%. The latter used to be
1605 derived from the former. The show command shows both parameters
1607 - Mountains are no longer a special case.
1608 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
1609 to 1.304, highway, bridge head, bridge span and bridge tower
1610 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
1611 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
1612 players can designate now cost the same at 0%. That's a feature.
1613 - Road infrastructure now reduces cost up to 90%, linear in road
1614 efficiency (used to be close to that, but non-linear). Same for
1615 rail infrastructure, but 99%. Adapted from Ice World V.
1616 - Double land unit minimum cost to 0.02, to slow them down on
1618 - Change land unit cost penalty in newly taken land to an extra 0.2
1619 instead of a minimum of 0.2, to reduce penetration depth.
1620 * Reduce bridge head defense and collect value to match highway's.
1621 * sinfrastructure displayed bogus rail mobility costs when there was
1623 * Retreating engineers took full landmine damage instead of half.
1624 * Fix socket creation code not to print a null pointer.
1625 * Fix login option code not to search beyond end of table (broken in
1627 * Spy planes and satellites can no longer spot landspies.
1628 * Spy planes can now spot surface ships at sea. They can no longer
1629 spot land units loaded on ships or land units.
1630 * Fix train retreat mobility cost, and don't permit retreat off rail.
1631 * Change maximum population to 100 for plains (was 49), mountains
1632 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
1633 the other habitable sector types (was 999).
1634 * Let minesweepers navigate at the speed their stats indicate by
1635 letting them sweep on the move at no extra mobility charge.
1636 * Reduce chance for planes to abort from 100-eff (if eff<80) to
1637 80-eff. This should make it easier to punch through air defense,
1638 flak in particular, and increase the risk of getting shot down.
1639 * Ship and land unit flak intensity is now proportional to efficiency.
1640 * Ship and land unit flak intensity is no longer scaled by the tech
1641 of the owner of the last thing firing. It's still scaled by each
1643 * All ships and land units firing flak now spot the plane and are
1644 spotted by the plane. Previously, spotting stopped as soon as flak
1646 * Inefficient land units were overcharged mobility when reacting.
1647 Broken when Empire3 changed land unit mobility use not to depend on
1648 efficiency, except for supply units.
1649 * New journal file to log complete player input plus selected
1650 important events. Controlled by new econfig key keep_journal, off
1652 * Fix unsafe shutdown on SIGINT and SIGTERM.
1653 * Fix land unit path finding: paths weren't always cheapest (broken
1654 in 4.0.2), and trains could be sent down paths without rail (never
1655 worked). Also fixes unit reaction path cost.
1656 * The custom table reader can now deal with sector, item, product and
1657 infra tables more comfortably.
1658 * Remove option BIG_CITY. Deities can customize the sect table to
1659 get the same effect.
1660 * Many more selectors can now be compared with names, not just
1661 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
1662 not fully work for queer names like &&&.
1663 * Let land units on missions support, just like ships.
1664 * Don't let units loaded on a train react.
1665 * Change update sequence to repair ships, planes and land units after
1666 sectors produce. This makes repairs use new avail instead of old.
1667 * Let players stop and start units.
1668 * Remove budget priorities.
1669 * Make plane report easier to understand.
1670 * Change land report to show carriers in the same format as plane and
1673 * Info file and manual page fixes.
1675 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
1676 * In conditionals, ~ compared to a string selector now stands for an
1678 * Change encoding of `not in any group' from " " to "". This makes
1679 fleet=~ work. It also affects xdump.
1680 * Fix plane capture code to clear wing.
1681 * People now eat and starve exactly the same in sectors, ships and
1682 land units. There used to be small differences, and civilians and
1683 uw loaded on land units didn't eat at all. The starvation command
1684 has been updated accordingly.
1685 * Fix bug that makes it impossible to assault or board with land
1686 units (broken in 4.3.4).
1689 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
1690 * Don't use non-portable groff features (broken in 4.3.0).
1691 * Work around potential crash bugs in command argument access.
1692 * Plug major information leak through nation selectors (broken in
1693 4.2.21). The fix unfortunately exchanges the meaning of xdump
1694 nation and xdump country. Sorry about that.
1695 * Minimize redundancy between (mortal's) xdump nation and xdump
1697 * New nation selector rejects.
1698 * xdump nation now shows foreign relations and no longer discloses
1700 * Fix crash bug in edit.
1701 * Fix number of planes building in budget command (broken in 4.3.3).
1702 * Selectors group, fleet, wing and army are now strings, and obvious
1703 syntax like fleet#a works. xdump also shows the strings now.
1704 Units not assigned to a group currently have group string " ", but
1705 that may still change.
1706 * Don't fold conditionals to lower case, because it breaks valid
1707 conditionals like fleet#A.
1708 * Mobility cost of a plane sortie is no longer limited to current
1710 * Various formulas no longer truncate or round intermediate results.
1711 * Interdiction mission charged twice the normal mobility cost for
1713 * Fix sail not to interpret negative x-coordinates as unsail
1715 * Improved configure script.
1718 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
1719 * power c can now show powerless countries. power c * works.
1720 * Fortresses now require 5% efficiency to return fire and interdict.
1721 * Range of ship return fire and support fire no longer depends on
1723 * Fix heap smash in login command client. Remote hole!
1724 * Properly destroy nukes on collapsing bridges. Before, you could
1725 rescue them by building a new bridge or arming them on naval
1727 * Nukes are now numbered like other units:
1728 - New selector type replaces selectors number and types.
1729 - New selector plane points to plane armed with this nuke.
1730 - New selectors effic, mobil, tech, group, opx, opy, mission,
1731 radius. Provided because all units have them; values are
1732 currently not interesting.
1733 - nuke command output redesigned.
1734 - ndump output changed subtly: nukes are no longer sorted by
1735 location, nukes in the same location no longer share id, and
1736 nukes on planes are shown.
1737 - transport nuke now works like transport plane.
1738 * arm and disarm now accept the common plane syntax, not just plane
1740 * Fix arm to let you change an armed plane's air-burst/ground-burst
1742 * territory no longer re-prompts when supplied with a bad argument,
1744 * edit lets you edit stuff that is actually computed from other
1745 state, like sector's coastal flag. This makes no sense and is now
1746 deprecated. Stuff deprecated since 4.2.15 is now gone.
1749 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
1750 * Fix security units' raid at the update (broken in 4.0.0, fixed only
1751 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
1752 increase. Make sure empty units don't kill anyone.
1753 * Fix bug in player_init(), which was most likely fatal on 64 bit
1754 hosts. Broken in 4.3.0.
1755 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
1756 * The order in which sectors were visited for `*' arguments disclosed
1757 the real origin, fix. Mapping commands used to work around this
1758 bug, until 4.3.1 exposed it there as well.
1759 * Code didn't compile on some systems.
1760 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
1762 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
1763 * Fix check of game state on server startup (new in 4.3.0).
1764 * sail now accepts a destination sector.
1765 * Tend could send bogus bulletins (broken in 4.3.0).
1766 * Plug memory leaks in mission command.
1767 * Close loophole in navigate that allowed players to find all sectors
1768 that are unfriendly or inefficient harbors or bridges.
1769 * Server didn't start when default econfig was missing and user
1770 didn't supply one with -e (broken in 4.3.0).
1771 * Retreat condition 'h' (helpless) never worked, fix.
1772 * Fix retreating mine sweepers to use mobility for sweeping.
1773 * Fix retreating land units to hit mines with the same probability
1774 and to take the same damage as in normal movement. Before,
1775 hit probability was higher, and damage was lower.
1776 * Ships could retreat into sectors owned by whoever made them
1777 retreat, but not in their owner's sectors.
1778 * Fix 'm' at the movement prompt of transport and test.
1779 * Fix march and test not to apply conditionals to sectors mapped,
1780 which led to spurious error messages.
1781 * Fix break not to respect conditionals. The bug let players keep
1783 * Fix retreat code not to respect conditionals. Attackers could
1784 abuse this to suppress fleet and army retreat orders.
1785 * Fix retreat and edit to zero-terminate retreat paths.
1786 Theoretically abusable for gaining information.
1787 * Fix format string crash bugs in load, spy and bomb.
1788 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
1789 ~p before the first line of text never worked.
1790 * Fix ancient bridge building race condition that could break the
1791 test whether the player can afford the bridge.
1792 * Fix trade lot change detection in set command. Can probably be
1793 abused to defraud sellers.
1794 * The pthread code now compiles under Solaris.
1795 * navigate and march now permit any whitespace between route and
1796 optional argument for radar, lookout, sonar, not just spaces.
1797 * Fix canal navigation (was broken in 4.3.0).
1800 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
1801 * version no longer pretends option SHIPNAMES still exists.
1802 * Remove files auth and ban. They could be used to restrict client
1803 address and user. Restricting user is useless, because players can
1804 send whatever they want. Banning IPs is better done with a packet
1805 filter. That leaves restricting deity IPs. Provide new econfig
1806 key privip for that. Apply it to session kill as well as login.
1807 * xdump escapes GUINEA_PIGS status:
1808 - xdump is now enabled unconditionally.
1809 - xdump sect now dumps selector coastal, because it can't be
1810 reliably computed from other xdump information.
1811 - New xdump realm and country. Realm information is now stored in
1812 a separate file, with appropriate selectors.
1813 - Reviewed for completeness and information leaks. See info xdump
1814 for remaining issues. New treaty selector uid, nat selectors
1815 relations, contacts. Removed useless selectors: news and lost
1817 - Command syntax changed.
1818 - xdump opt is no more, option information is now in xdump ver.
1819 - xdump can now dump meta-data.
1820 - Header and footer changed to be more compact. You now need
1821 meta-data to identify fields.
1823 - Documentation in doc/xdump.
1824 * New econfig key builtindir.
1825 * New econfig key custom_tables lets you customize configuration
1826 tables without recompiling. Customizing tables other than unit
1827 tables is not recommended for now. See doc/econfig for
1829 * Check configuration and game state are sane on server startup.
1830 * Remove option NONUKES and NEUTRON. Deities can load a suitable
1831 nuke table to get the same effect.
1832 * Remove option DRNUKE. Use econfig key drnuke_const to control
1833 whether nukes need research.
1834 * Disqualify land units from performing missions while loaded on
1836 * Fix dump for strings without terminating zero.
1837 * Fix login command option not to send an extra prompt.
1838 * zdone now displays information about demand update vetoing.
1839 * The Windows port now requires Winsock version 2.
1840 * Remove econfig key powe_cost.
1841 * version report now shows all the configurable settings of interest
1843 * carg and lcarg now display people as well.
1844 * ldump now dumps civ and uw as well.
1845 * Fix dangling pointer dereference in dogfighting code.
1846 * Tell sector owner when partisans take over. But don't disclose che
1848 * emp_server, files, fairland now support options -h and -v.
1849 * Simplify baroque version numbering to a single version number.
1850 This affects output of version.
1851 * New show item and show news.
1852 * New build process:
1853 - Follow the usual steps: configure; make; make install. The
1854 latter is optional. The only file deities still have to edit is
1856 - Use GNU Autoconf for system configuration.
1857 - Use GNU Make for portability and features.
1858 - Support separate build trees.
1859 - Remake out-of-date dependencies automatically.
1860 - Remake out-of-date info files automatically.
1861 - Flatten info directory.
1862 - Formatted info files are no longer distributed in source tarball.
1863 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
1864 low-level options doesn't seem to be worth the effort, as
1865 UCONTEXT should be pretty portable.
1866 * Fix use of freed memory in sail.
1867 * sail could let large ships enter big cities.
1868 * Fix reject and accept not to require contact.
1869 * Fix sharebmap and telegram to prompt for a missing first argument.
1870 * Fix report to align column research correctly for deities.
1871 * When the optional newspaper argument doesn't work because HIDDEN is
1872 enabled, complain instead of ignoring it silently.
1873 * When BLITZ is enabled, fairland no longer permutes country numbers
1874 in newcap_script so that start islands are ordered from top left to
1876 * Minimize output format differences between options:
1877 - census shows column fall regardless of FALLOUT.
1878 - show nuke now shows column res regardless of DRNUKE.
1879 - report no longer suppress column status when HIDDEN is enabled.
1880 HIDDEN limits status information like for the country command.
1881 - relations column width differed depending on option SLOW_WAR.
1882 Always use the wider format.
1883 * Fix a bug in edit that suppressed the player notification telex on
1884 military reserve change.
1885 * Fix command dispatch not to let deities use commands that are
1886 declared not to be available to them. The only command affected is
1888 * Fix the list command for visitor.
1889 * econfig key m_m_p_d no longer applies to deities.
1890 * Fix the origin command for country #0. Allow moving origin to
1891 another country's origin. Allow deities to reset origin to
1892 absolute 0,0. This turns origin into a superset of the offset
1893 command. Remove offset command.
1894 * Fix a bug that caused unpredictable flak damage when it should have
1895 been maximum damage (was broken in 4.2.19).
1896 * Don't store initial capital location, remove the associated nat
1897 selectors xstart, ystart.
1898 * Fix production command to consider resource depletion.
1899 * Fix justification of coordinate output in cutoff and mission.
1900 * Option UPDATESCHED is no longer optional. Disabling it didn't
1903 * Turn options into ordinary econfig keys.
1904 * New econfig key start_cash.
1905 * BTU regeneration now depends on the capital's work percentage.
1906 * nation now supports an optional argument that lets deities ask for
1907 somebody else's nation report.
1908 * Fix nation to display SANCTUARY instead of VISITOR for countries in
1910 * Fix capital to let you use a regained sacked capital without
1911 activating another one in between.
1912 * Don't move capital when it is sacked.
1913 * New ship capability canal, replacing obscure formula based on build
1915 * You now need a capital to request a demand update.
1916 * power now ignores landspies.
1917 * Fix LWP stack checking.
1918 * Clean up LWP, drop dead machine-specific code, fix portability bugs
1920 * census now shows the old owner instead of `*'. dump is unchanged
1921 to avoid breaking clients.
1922 * peek no longer prints the old owner.
1923 * When a bombed land unit retreated, collateral damage was applied to
1925 * paradrop, drop and fly can no longer abandon the base sector.
1926 * Tending foreign ships now sends a bulletin to the owner.
1927 * Fix bug that permitted login for inactive countries, including ""
1928 * Fix tend for spies.
1929 * Change launch to fire all missiles selected at the same target.
1930 Previously, it prompted for a new target after each missile.
1931 * add, consider, build, launch and fire no longer re-prompt when
1932 supplied with a bad argument, they just fail. Consequently, the
1933 build command no longer lets you list types you can build. It
1934 points to the show command instead.
1935 * Fix add not to truncate country number.
1936 * Fix selector coastal to be accurate at all times.
1937 * Fix obscure bug in fairland: the sector added last to an island
1938 wasn't considered coastal. Affected resource computation.
1939 * Fix sector wiping in add command.
1940 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
1941 ways. Custom configuration tables should become a serviceable
1942 replacement eventually.
1943 * Client no longer freezes on long lines of server output.
1944 * Fix uninitialized signal mask bugs.
1945 * Fix Windows service code's treatment of -e.
1946 * Sub interdiction disclosed sub owner through news' actor selector.
1947 * country reports on all countries, but carefully limits information
1948 disclosed to mortals. Output format changed.
1949 * Market no longer forces sellers to grant loans.
1950 * Fix potential crash bug in set command. Friendlier prompt and
1952 * Substantial code cleanup and portability fixes.
1953 * Extend empfile abstraction to cover game configuration.
1954 * Overhaul of game state storage.
1955 * The above includes major contributions from Ron Koenderink. Many
1958 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
1959 * Make version pretend option SHIPNAMES still exists, for the benefit
1960 of clients that still depend on it.
1961 * The change to conv in 4.2.22 could crash or compute incorrect
1963 * Info updates missing in 4.2.22.
1964 * A few code cleanups.
1966 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
1967 * Log player login, logout and session kill.
1968 * Close loophole in assembly point rules that allowed players to find
1969 all unowned sectors. The assembly point must now be owned by you
1970 or an ally, or you or an ally must have a ship there.
1971 * Don't let embarked land units fire flak.
1972 * Fix display of the last connection's host when the host name was
1974 * Fix change command to accept full length representative (password),
1975 currently 19 characters. It used to chop off after eight
1977 * Non-recon missions no longer establish contact to owners of
1978 overflown sectors, because those missions do not identify the
1979 owner. This matches info Hidden.
1980 * The following events now establish contact:
1982 - Sighting a ship when toggle coastwatch is off
1983 - Spotting overflying planes
1984 - satellite spotting land units
1985 - lookout and llookout spotting ships, planes and land units
1986 - Any relations change
1987 * The country command's `temporary' state of disorder ended after
1989 * Telegram notifications could get lost in exotic circumstances,
1990 e.g. while a second client attempted to connect. Can be abused for
1992 * Remove option SNEAK_ATTACK.
1993 * Fix lboard not to let you board dead land units.
1994 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
1996 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
1998 * Fix fly to let the player abort the command at the last prompt.
1999 * Client no longer reads execute scripts in binary mode under
2001 * New econfig key listen_address.
2002 * econfig key port can now be a service name. Service empire no
2003 longer takes precedence over econfig.
2004 * Client falls back to compiled-in host only if environment doesn't
2005 supply one, not if it can't be resolved. Same for port.
2006 * Oil derrick could extract slightly more oil than was in the ground.
2007 * test command checked start sector for space and some other things
2008 instead of end sector.
2009 * convert now silently limits conversions to avoid exceeding maximum
2011 * shoot no longer limits you to 999 victims.
2012 * 4.2.19 broke pin-bombing commodities on some platforms.
2013 * Don't block on output while update is pending. This is required to
2014 ensure the update can abort commands.
2015 * Commands submitted while the update is waiting for commands to
2017 * The force command no longer waits for the specified time. It
2018 starts a scheduling thread instead, just like shutdown.
2019 * Correct grammar and punctuation in output of version.
2020 * Option SHIPNAMES is no longer optional.
2021 * Fix output of qorder and sorder for ships with sail path.
2022 * Don't change capital to agribusiness on retake. From Pat Loney.
2023 * bdes prompt for new designation was messed up for empty bmaps.
2024 * Client now supports pipes under Windows.
2025 * Care for subtle Windows socket incompatibilities.
2026 * Fix strength command not to lie about units reacting into
2028 * strength now yields the processor periodically, to keep the game
2030 * Schedule commands more fairly. Previously, a sufficiently fast
2031 player could starve out the others.
2032 * launch assumed plane maximum mobility 127 for calculating when
2033 satellites will be ready to use.
2034 * Drop support for for DCE threads.
2035 * Drop support for pthread implementations lacking pthread_kill().
2036 This includes ancient versions of OS X.
2038 * Minor info file fixes.
2039 * The above includes major contributions from Ron Koenderink. Many
2042 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
2043 * Don't let threads block on output to another player thread's
2044 socket. Such blocking violates basic design assumptions and can
2045 cause all kinds of grief. In particular, it causes player session
2046 hangs under Windows with 4.2.20. Broken since the introduction of
2047 flash and asynchronous telegram notification many years ago.
2048 * Threads sleeping until a specified time could return early under
2049 Windows. This could cause double-updates.
2050 * Fix fallout damage (was broken in 4.2.19).
2051 * Fix show sector s (was broken in 4.2.19).
2052 * Fix deliver not to deliver friendly civilians into occupied
2054 * Fix mil duplication in board (was broken in 4.2.14).
2055 * Fix stack smash in lrange, shoot and execute. Remote holes, and
2056 the last one doesn't even require authentication.
2057 * Fix crash bug in emp_config parsing.
2058 * Fix buffer overruns in turn and shutdown.
2059 * Fix second argument of shutdown.
2060 * announce, pray, telegram and turn now abort on EOF.
2061 * Fix display of MOTD and game down message of maximum size.
2062 * Correctly support telnet line termination on input. Previously,
2063 carriage returns could slip into ship names and such.
2064 * Fix flash not to lie about recipients that are just logging in.
2065 * Remove obscure login command list.
2066 * Convert client from obsolete termcap to terminfo, and clean up
2068 * New fairland option -h to print usage information. Improved
2069 command line syntax diagnostics. Exit unsuccessfully on unknown
2071 * fleet and army now copy retreat orders of the fleet's or army's
2072 first member with group retreat orders in the same sector.
2073 Previously, they used the retreat orders of the first fleet or army
2074 member, which is less than useful, and failed to take ownership
2075 into account, which is an abusable bug.
2077 * Fix xdump not to disclose other countries' losses.
2078 * Fix exit status of files program when it can't create files.
2079 * Support UTF-8 encoded Unicode in human-human communications. This
2080 affects MOTD, game down message, telexes, announcements and flash
2081 messages. See new doc/unicode for technical details.
2082 * New login command `options' for client/server option negotiation.
2083 See new doc/clients-howto for technical details. The only option
2085 * emp_client -u now requests UTF-8. This requires a terminal that
2087 * Fix news for land unit defensive support.
2088 * Properly mark sea mines hit by retreating ships. Unmark mines
2090 * Fix diagnostics for unknown selector names in conditionals (was
2092 * Fix selector name clashes: rename ship selector mobquota to mquota,
2093 land selector for reaction range limit from rad to rmax.
2094 * Fix Windows services for relative file names on command line or in
2095 econfig (was broken in 4.2.20).
2096 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
2097 are now float. This gives deities finer control over maximum
2099 * Fix production command for sectors with 60% efficiency.
2100 * Improve syntax of read for deities.
2102 * Some info topic names differed only in case, which loses on
2103 case-insensitive file systems, and is a bad user interface even
2104 when it works. Change those names. Rename deity command hidden to
2105 peek because its info topic clashed with that of option HIDDEN.
2106 * Thanks to Doug Wescott sheep are finally covered properly in info.
2107 * Documentation fixes.
2108 * Much of the above was contributed by Ron Koenderink. Many thanks!
2110 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
2111 * When units in different sectors marched, only units in the sector
2112 with the highest-numbered unit were interdicted. A marching
2113 non-spy made all marching spies visible to interdiction regardless
2115 * Fix crash when interdiction sinks second ship in a sector. Broken
2117 * Fix an ancient bug in simulation of level production that clobbered
2118 stack and could lead to low predictions, typically zero, which
2119 screwed up budget. The bug had no effect until 4.2.19.
2120 * When a sector revolts, and there wasn't enough space to liberate
2121 all uw, the number of remaining uw got the wrong sign. Broken in
2123 * Log and abort when LWP stack check detects stack smash. Server
2124 option -s no longer implies -p.
2125 * The native Windows build now supports -p and -s.
2126 * The native Windows build now properly deals with ^C when running in
2127 the foreground. It no longer prompts for a quit command on the
2129 * The meaning of server option -D in presence of -e is unclear.
2130 Other programs only support -e. Remove option -D. Use -e
2131 DIR/econfig instead of -D DIR.
2132 * New server option -v shows version information.
2133 * Fix the server's exit status with -h. Broken in 4.2.19.
2134 * The linux-pthreads build failed to shut down on signals.
2135 * Fix threading bugs in the native Windows build that made shutdown
2136 unsafe and screwed up update aborting commands.
2137 * New econfig key pre_update_hook to allow automatic, safe backup
2138 right before the update. See scripts/backup for an example.
2139 * The server now prints log messages to stderr as well when running
2141 * Fix potential buffer overflows in logerror() and lwpStatus().
2142 * Server now requires POSIX signals. It no longer catches SIGUSR1.
2143 * Remove support for ancient versions of HP-UX.
2144 * Fix seeding of PRNG broken in 4.2.19.
2145 * Don't reseed the PRNG in commands, it hurts randomness and could be
2146 abused by crafty players.
2147 * The server now makes the data directory its working directory.
2148 This also gets rid of a bug that changed the file name of the
2149 sector, power, nation and lostitems file unless econfig could not
2151 * The server now writes a pid file. Thanks to Daniel O'Connor.
2152 * More user friendly server startup: more errors are detected while
2153 the server still runs in the foreground, which makes it possible to
2154 complain to stderr and to exit unsuccessfully.
2155 * Early log messages went to the log file in the default data
2156 directory, even though econfig specifies another data directory.
2157 * Specifying an econfig file on the command line that can't be read
2159 * Errors in econfig are now fatal.
2160 * The server now refuses to start when it can't open data files.
2161 * News are now sorted and expire sanely.
2162 * Conditionals can now compare strings as well.
2163 * Corrupted down and motd files could cause buffer overflows.
2164 * Fix recon to let player abort at the flight path prompt.
2165 * power no longer rounds worldwide numbers for deities.
2166 * power command failed to recognize deities with non-zero country
2168 * Change output of production command so that columns are aligned
2169 even for large values. Replace column wkfc by more useful column
2171 * neweff and production miscalculated work when mil exceeded
2173 * neweff miscalculated work when the population limit exceeded 999.
2174 * Fix capping of avail when a big city is torn down.
2175 * Fix a bug in fire that allowed players to find all submarine uids.
2176 * Maximum sector population is no longer hardcoded, and now covered
2177 by xdump. Option RES_POP now affects mountains and plains as
2178 well. From Ray Hyatt.
2179 * Fix fina and news not to ignore errors in conditions.
2180 * The native Windows build now requires Windows Sockets 2.
2181 * The native Windows build now supports multiple instances of the
2182 service. The ability to supply additional startup parameters to
2183 the service has been removed.
2184 * Implement fairland command line parsing under Windows.
2185 * Improved fairland and emp_server usage message.
2187 * Minor info file and documentation fixes.
2188 * Much of the above was contributed by Ron Koenderink. Many thanks!
2190 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
2191 * Fix order not to unload into full sectors.
2192 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
2194 * Fix distribute not to conjure up a civilian when importing
2195 civilians from a dist center that doesn't have any.
2196 * Fix flak to resupply no more shells than actually needed.
2197 * Fix rounding error in shoot that could result in more people shot
2198 than actually there.
2199 * Fix info and apro error handling. In particular, do not leak
2200 potentially sensitive information on the server to players.
2201 * info no longer shows a random matching page when the topic argument
2202 is ambiguous. Instead, it lists all matching topics.
2203 * Embarked land units and overflying planes no longer spot each
2205 * Fix show command to show only sectors that players can designate
2206 (was broken in 4.2.18).
2207 * Fix a rounding error in production command column `max'.
2208 * Fix production command for overpopulated mountains and plains.
2209 * Fix tradeship ally cut to match documentation.
2210 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
2211 * Fix a bug in aerial sonar where ships could mask submarines with
2212 the same number modulo 256.
2213 * Don't allow bombing of subs that were not detected.
2214 * MOTD and the game down message are now entirely separate: use `turn
2215 motd' for the MOTD, and `turn on' and `turn off' for the game down
2216 message. `turn on' no longer lets you edit the MOTD.
2217 * Remove option NUKEFAILDETONATE.
2218 * Option ORBIT is no longer optional.
2219 * New option GUINEA_PIGS to control experimental stuff not ready for
2220 prime time. If your deity enables this in a serious game, run!
2221 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
2222 * New ship and land selectors rflags, rpath.
2223 * New ship selectors for order: xstart. xend, ystart, yend,
2224 cargostart, cargend, amtstart, amtend
2225 * New ship selectors for sail: mobquota, path, follow.
2226 * New news selector uid.
2227 * Implement command line parsing under Windows where it was missing.
2228 * emp_server and and files print a usage message on command line
2230 * Fix how emp_server exits after being panicked by a signal. It can
2231 now dump core when this happens.
2232 * Fix bug in client that could crash it when a line of input starts
2234 * Client now gets user name from environment variable LOGNAME if set,
2236 * The native Windows build can now run as a service.
2237 * Redirecting client input now works under Windows.
2239 * Don't confuse work with loyalty in info Citizens.
2240 * Minor info file and manual page fixes.
2241 * Much of the above was contributed by Ron Koenderink and Marc
2242 Olzheim. Many thanks!
2244 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
2245 * Fix info to accept abbreviated arguments under Windows. From Ron
2247 * Buying planes or land units loaded on something didn't work when
2248 that something moved.
2249 * Fix a bug that could produce update cascades with update policy
2251 * Fix delivery and distribution to grant packing bonus only to
2252 efficient sectors, just like move. Previously, delivery ignored
2253 efficiency, and distribution behaved as if it were an efficient
2254 sector without special bonuses.
2255 * New sector selectors loyal, access; ship selectors radius, access,
2256 xbuilt, ybuilt, builder, name; plane selectors radius, access,
2257 theta; land unit selectors radius, react, nland, access; lost
2259 * Fix sector selectors che, che_target; plane selectors att, def;
2260 nuke selector types; treaty selector exp; news selector time;
2261 commodity selectors type, xbuy, ybuy.
2262 * Option PLANENAMES is no longer optional.
2263 * Ensure config parameter variables and their description in
2264 configkeys[] are consistent. Inconsistencies there caused bugs in
2265 the past. From Marc Olzheim.
2266 * Complain if econfig file can't be read.
2267 * Better messages for errors in econfig file.
2268 * Remove unused econfig keys hard_tech and last_demand_update.
2269 * New econfig key news_keep_days to configure news expiry.
2270 * New econfig key anno_keep_days to configure announcement expiry.
2271 * Fix announcement expiry. It leaked file descriptors and memory,
2272 and could corrupt the anno file. From Ron Koenderink.
2273 * New command xdump: experimental extended dump. Disabled for now.
2274 * Bankers no longer round down debts, and they collect interest for
2275 the time debtors are idling at sub-prompts.
2276 * Loan interest calculation was broken at the due date and after a
2277 last payment made at the due date. With luck, debtors could abuse
2278 this to repay loans cheap (they couldn't gain cash, though), sharks
2279 to purchase loans cheap, and creditors to collect excessively.
2280 * Fix major bug in transport that allowed two cooperating countries
2282 * Don't report interdiction damage twice when transporting planes.
2283 * Fix message for attempting to transport a plane in a sector not
2284 owned by the player.
2285 * Fix confusing diagnostics when refusing to improve defense because
2286 option DEFENSE_INFRA is off.
2287 * Simplify confusing code in budget.
2288 * Fix spacing in output of budget and show.
2289 * Change one-way plane sorties to match ordinary sorties: offer
2290 carriers regardless of the sector they're in, require carriers to
2293 * Don't print owner of incoming missile twice when intercepting it.
2294 * Simplify constituent storage in product characteristics.
2295 * Replace remaining `variables' leftovers; mainly in unit
2297 * Remove leading spaces in deity unit dumps.
2298 * Replace inappropriate uses of compile time constant ETUS by 60.
2299 Deities don't change ETUS, they change etu_per_update by editing
2300 econfig. This nonsense dates back at least to chainsaw 3.31.
2301 * Change ship production (fishing and drilling for oil) to match
2302 sector production. Ship efficiency and tech are now relevant, and
2303 all people on board work. From Ron Koenderink.
2305 * Minor info file fixes.
2307 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
2308 * Fix seeding of PRNG under Windows. The bug made updates occur at
2309 a predictable time in the update window. From Ron Koenderink.
2310 * Close major loophole in drop that allowed players to determine
2311 whether an arbitrary sector is sea, allied land, or other land.
2312 * fly could fly civilians into occupied sectors. For consistency
2313 with other means to move around stuff, this is no longer possible.
2314 * Don't allow flying to a carrier that doesn't have space for the
2315 planes. Previously, planes that did this were teleported home,
2316 which could be abused.
2317 * Close loophole in bomb that allowed players to find all
2319 * Fix move and explore not to crash when moving civilians to a sector
2320 without civilians, and interdiction destroys them all. Found and
2321 debugged by Jeff Cotter.
2322 * Fix printing of messages entered with turn command. '%' characters
2323 could cause havoc, even crashes.
2324 * Use sector's actual maximum population to compute chance of plague
2325 outbreak. Previously, code used 9999 for big cities and 999 for
2326 other sectors, and info Plague said 999. This makes all crowded
2327 sectors equally vulnerable, even mountains, plains, and inefficient
2329 * Oil derricks no longer drill and deplete more oil than they can
2330 hold. From Ron Koenderink.
2331 * Version 4.2.15's coordinate and list parsing fixes reject trailing
2332 junk. That's too strict. Silently ignore trailing junk as long as
2333 it starts with whitespace.
2334 * Version 4.2.15's selector rewrite broke some type literals,
2335 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
2336 type literals to selectors.
2337 * Nightly build patches game to get repeatable PRNG results. From
2340 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
2341 * Previous version broke sector production when part of the work is
2342 used for sector construction. Fix courtesy Jeff Cotter.
2343 * Add rudimentary tests to nightly build. From Marc Olzheim.
2345 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
2346 * test command no longer asks whether to abandon the sector.
2347 * explore command could generate a bogus `lost' record when it
2348 regains an abandoned start sector.
2349 * edit command now properly updates stats when editing tech level of
2350 ships, planes or land units. A few of these stats can be edited
2351 separately, which doesn't make much sense, and is now deprecated.
2352 * edit command no longer accepts efficiency values that would destroy
2353 the edited unit. Deities can still delete units by setting the
2355 * upgrade command used to charge an amount of avail that didn't match
2356 info upgrade. Neither the implemented nor the documented amount
2357 made much sense. Change it to 15% of the full build cost. Rewrite
2359 * Commands upgrade and build could be off by one when reporting
2361 * upgrade command reported rounded cost but charged unrounded
2362 cost. Round cost of upgrade down to match behavior of build.
2363 * Upgrading planes now preserves range when it is less than the
2364 maximum range. It used to set it to the new maximum range.
2365 * show bridge and show tower no longer claim bridge building requires
2366 `workers' (whatever that is), since it doesn't.
2367 * Replace option ROLLOVER_AVAIL by econfig parameter
2368 rollover_avail_max, which is the maximum amount of avail that rolls
2369 over. Previously, avail was limited after rollover, and even when
2370 ROLLOVER_AVAIL was off. Fix that.
2371 * Ships weren't always charged mobility for firing with option
2373 * Fix shell use of return torpedoes.
2374 * designate no longer complains twice about deity only designations.
2375 * Ensure designate zaps efficiency only when sector type really
2377 * Fix strength to always report mines to deities.
2378 * Remove option SHIP_DECAY.
2379 * Fix bug in sonar that could crash or yield unpredictable results
2380 near the true origin.
2381 * Fix buffer overflow in flash and wall.
2382 * Fix wall not to strip out first word of message.
2383 * Change market and order to use item types instead of mnemo
2384 characters internally.
2385 * Market now reports sales with full item names instead of single
2387 * buy now requires first argument to be an item name, as documented.
2388 * production command handled production backlog incorrectly, failed
2389 to limit production for production efficiency greater than one,
2390 e.g. agribusiness, and incorrectly limited raw material
2391 consumption. Also fix a rounding error. With help from Ron
2393 * Sector work was accidentally truncated to even.
2394 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
2395 don't divide SHRT_MAX+1.
2396 * Properly diagnose over-long unit lists.
2397 * Rewrite selector code. Old code let players smash the stack by
2398 supplying too many conditions. New code properly rejects ambiguous
2399 abbreviations and prefers exact matches. Selectors with names that
2400 collide with types, like land units' rad and spy, now work.
2401 Selectors with non-integral values, like land units' att, now work.
2402 * survey used to display hundreds for everything but variables. Now
2403 it displays hundreds only for values that can be large.
2404 * Rewrite info survey. Document ability to survey properties other
2405 than items and resources.
2406 * Rewrite info build, since it was inaccurate and poorly structured.
2407 * Fix info fire on required military. From Marc Olzheim.
2408 * New fairland argument -R to set the PRNG seed. Print the seed.
2409 This allows you to recreate the same world again.
2410 * New facilities to deal with internal errors. These crash when the
2411 server is started with -d, which is appropriate for debugging, and
2412 potentially disastrous for running a real game.
2413 * Automated nightly builds.
2416 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
2417 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
2418 * Gripe about unknown options in econfig.
2419 * Remove option GRAB_THINGS.
2420 * Utility program files takes new option -f.
2421 * Remove utility programs land, ore and perfect, which don't compile
2422 since 4.2.0 (Oct '98).
2423 * fairland no longer warns when it added resources, but when it
2425 * Fallout code could claim destruction of more items than actually
2427 * Fix recursive resupply (resupply from supply land unit triggering a
2428 resupply of the land unit) when just testing for how much can be
2429 resupplied. The bug could have led to insufficient resupply.
2430 * Fix recursive resupply not to consume all fuel in supply units. No
2431 supply units consuming fuel exist in the stock game.
2432 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
2433 Distribution threshold were previously limited to 10000, and
2434 delivery thresholds to 65528.
2435 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
2436 used to limit to 9990. Market transactions and commands explore,
2437 move, drop and fly to 32767. Limiting in autonav code (order
2438 command) didn't work. Item delivery used to stop at 9990,
2439 distribution at 9999. Food growing and sector production used to
2440 stop at 9999. Grind, assault lunchboxes, demobilization, mine
2441 sweeping and che liberating uw could theoretically attempt to
2442 increase items beyond 65535, which would have been ignored
2443 (destroying the increase).
2444 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
2445 fallout increases behaved inconsistently. Increases beyond 65535
2446 could get ignored, or fallout could saturate at 9999, or it could
2447 overflow at 65536 (that would take quite some nuking, though).
2448 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
2449 operation that would have gone beyond 65535 was ignored.
2450 * Fix `are we loading or unloading' tests for load, unload, lload and
2452 * Fix editing of land unit attack and defense values. Implement
2453 editing of ship defense values. Contributed by Ron Koenderink.
2454 * edit now edits che number and target separately.
2455 * Fix edit to properly extend unit files. Contributed by Ron
2457 * Major internal reorganisation: Sectors need space for items,
2458 deliveries and distribution thresholds. To save space, the
2459 ancients invented `variables': a collection of key-value pairs,
2460 missing means zero value, space for `enough' keys. This
2461 complicates the code, as assigning to a `variable' can fail for
2462 lack of space. Over time, `enough' increased, and for quite some
2463 time now `variables' have been *wasting* space. Replace them,
2464 except in unit characteristics, where they are read-only, and will
2465 be replaced later. This also removes misfeatures like plague
2466 outbreaks silently deleting deliveries.
2467 * Remove disabled commands dissolve and mult. Remove configuration
2468 parameters minmult and maxmult.
2469 * trade command indexed an array out of bounds when attempting to
2470 display the plague as commodity. Fix.
2471 * New make goal interix. Contributed by Ron Koenderink.
2472 * The type selector now prefers an exact match to a partial match.
2473 ?type=sb now selects sb, not sbc, even when sbc happens to be found
2475 * Value of selector sell was always zero, remove it.
2476 * Clean up selector code.
2477 * satellite now displays all sectors owned by other players, and none
2478 else. It used to display all but sea, mountains, sanctuaries,
2479 wasteland and wilderness.
2480 * map commands now display wilderness and plains owned by other
2481 players as '?'. Radar commands now display all wilderness and
2483 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
2484 * Make client abort the current command on ^C under Windows, as
2485 everywhere else. Contributed by Ron Koenderink.
2486 * Command line parser interpreted trailing whitespace as an another
2487 (empty) argument. Ignore it instead.
2488 * Properly declare stuff in headers, include proper system headers.
2489 Remove all nested external declarations. Source code is now fully
2490 prototyped. Enable appropriate gcc warnings.
2491 * Fix several type errors. Some may have been show-stoppers on big
2492 endian machines where sizeof(long) != sizeof(int).
2493 * Remove pre-ISO C compatibility cruft (hey, it's been only fifteen
2495 * Various portability fixes. Some bugs may have been show-stoppers
2496 when sizeof(long) != sizeof(int). With help from Marc Olzheim and
2498 * Move some code to more logical places. Remove some unused code,
2499 some of which was hard to port.
2500 * The files program could print error messages to a log file in some
2501 circumstances. Make it print to stderr.
2502 * deliver can now change direction without changing the threshold.
2503 * deliver now provides appropriate context when prompting for
2505 * Login command play no longer ignores up to two arguments if there
2507 * Fix payoff (was broken in 4.2.13).
2508 * Capability fish didn't work together with capability oil.
2509 * Fix and clarify plague outbreak chance in info Plague.
2510 * Fix RES_POP maximum population in info Research.
2511 * Fix info telegram and info announce on ~ escapes.
2512 * Update info Selector to match code.
2513 * Document all undocumented unit capabilities and stats.
2514 * Document submarines' ability to carry landspies.
2515 * Fix info shoot on security units.
2516 * Various small info file fixes.
2517 * Many fixes in the troff macro package for info files.
2518 * Many fixes for translating info files to HTML.
2519 * Many info file markup fixes.
2521 Changes to Empire 4.2.13 - Fri Feb 13 22:12:36 UTC 2004
2522 * Source code reindented and cleaned up somewhat.
2523 * Various small info file fixes.

2533 * Minor security fix: doconfig now writes example auth entry as
2535 * Fixed reading of country name and password in client for Windows.
2536 * Replace use of some obsolete non-portable library functions by
2537 portable equivalents.
2538 * designate now warns about redesignated capital only when it
2539 succeeds in redesignating the capital.
2540 * attack could be off by one when reporting required unit mobility.
2541 * Fixed command matching. Unique prefixes were not always
2542 recognized, and junk suffixes were ignored.
2543 * Removed bestdistpath. bestpath yields the same results.
2544 * Renamed lstats to lstat for consistency and to match info page.
2545 * Fixed non-portable fd_set * arguments of select().
2546 * New `map' flag `h' to highlight own sectors. Contributed by Marc
2548 * Fixed `sabo' reporting damage to player in deity coordinates.
2549 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
2550 * Fix Windows server shutdown on reading "quit" from stdin.
2551 * Land units now fortify automatically when mobility plus growth
2552 exceeds the maximum. With code from Marc Olzheim.
2553 * Wandering che are less predictable.
2554 * Land units no longer regenerate mobility faster while it is
2556 * Fixed emp_client -k.
2557 * No longer allow pirates to ferret out where a ship was built.
2558 * Fixed map commands to reject bmap flags `t' and `r' instead of
2560 * Fixed lmine shell resupply.

2573 * Fixed multiple cases where return value of getstarg() was
2574 used without being checked which crashed the server.
2575 * Used stdarg.h instead of varargs.h.
2576 * Call only_subs and save result before mission frees attacker
2577 list. Call with free list could cause server crash.
2578 * Fixed spy sat map for units on opposite side of world wrap.
2579 * Don't sleep in main thread when called from signal handler.
2580 * Fixed error checking in pthreads.
2581 * Properly detach pthreads.
2582 * Pass unlocked mutex to pthread_mutex_unlock.
2583 * Cope with interrupted sleep in pthread empth_sleep to prevent
2585 * Added server configurable update window.
2586 * Initialized variables passed to setsockopt in accept.c.
2587 * Fixed bug where sharing bmap with uncontacted country crashes

2591 * Added compile option for the Mac OSX architecture.
2592 * Fixed bug in cargo where unit array was indexed by shp_maxno
2593 instead of lnd_maxno.
2594 * Fixed bug in reject where aborting the command crashes the
2596 * Can't buy land units into enemy headquarters.
2597 * Added sabotage command and commando unit.
2598 * Spies moving by themselves will not trigger interdiction.
2599 * Fixed error in map distance calculation that caused errant

2617 wouldn't be kicked off during long flashes or writing telegrams.
2618 * LOSE_CONTACT will work as advertised.
2619 * Allied units marching through 0 mobility conquered sectors
2620 are charged at least LND_MINMOBCOST.
2622 Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001
2623 * Assault can reinforce own sector when SLOW_WAR is enabled.

2625 pipes, and file redirect match players input.
2626 * Added pboard command to capture enemy planes in your territory.
2627 * Declaring war when at Sitzkrieg won't return relations to Mobilizing.

2672 Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
2673 * Added new NF_SACKED flag to indicate when a country has had it's
2674 capital sacked. This flag is only cleared when the country actively
2675 redesignates it's capital using the "capital" command, and changed
2676 capital.t to reflect this (no more re-sacking after an update if the
2677 country doesn't reset and repeating until they are out of cash.)
2678 * Added land unit to edit command for planes.
2679 * Added nuketype to edit command for planes.
2680 * Changed so that if the leader of a group of units is a train, the
2681 railways are used for bestpath instead of roadways.
2682 * Changed mission command to also print reaction radius of reserve
2683 missions when set for land units.
2684 * Changed Flak.t to reflect guns having to be loaded onto a land unit
2686 * Changed so that visitor countries cannot change their name or password.
2687 * Changed so that you cannot upgrade deity planes, ships or units.
2688 * Changed so that you know where missions are flown from.
2689 * Changed so that the airport owner you fly a mission from is informed.
2690 * Changed so that preperations for takeoff are reported to the owner of
2691 the sector, ship or unit a plane is taking off from if it is not owned
2692 by the owner of the plane.
2693 * Changed so that when a sector reverts during a guerrilla revolt, the
2694 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
2695 you would always get at least an updates worth of mobility. With
2696 MOB_ACCESS, sectors that reverted during the update were useless, since you
2697 got no mobility for a long time. This fixes that problem, and makes che
2698 more useful as well.
2699 * Changed so that air defense missions don't always send up every plane in the
2700 area, but instead always send up at most two times the number of incoming
2701 planes (for each interdicting country.) This helps to stop 1 plane from
2702 stripping the mobility from 25 air defense planes all at once, but doesn't
2703 limit it to n+1 as there is for regular interception.
2704 * Clarified deity reversion of sectors in Sector-ownership.t
2705 * Clarified production efficiency and added pointer to "show sector cap"
2707 * Clarified nuketype selector for planes in Selector.t
2708 * Clarified that fortifying units does not affect mission status in info
2709 pages for mission and fortify.
2710 * Clarified fuel syntax upon error in fuel command in empmod.c.
2711 * Cleaned up comments causing minor complaints in some builds.
2712 * Fixed bug in loans where you could collect on proposed loans.
2713 * Fixed production command to be more accurate (though it *still* has some
2714 rounding errors, it's better.)
2715 * Fixed potential memory leak in air defense missions.
2716 * Fixed bug where you couldn't pinbomb some commodities if other commodities
2717 didn't already exist in the sector.
2718 * Fixed bug where you couldn't build 0 crew planes without military in the
2719 sector. (This is different from needing at least 1 military to build all
2720 planes that need a crew which introduced another related bug earlier.)
2721 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
2722 messages to be displayed for deity owned planes.
2723 * Fixed bug where land units on ships in a sector taken over were blown
2725 * Fixed bug where planes on ships in a sector taken over were blown up
2727 * Fixed bug in sdump printing origx and origy in deity coordinates.
2728 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
2730 * Fixed bug in launch showing wrong satellite target (showed asat instead
2731 of the target satellite.)
2732 * Fixed bug where you could gain information not normally available using
2733 the "fire" command to determine sector type information.
2734 * Fixed bug in market/trade creating extra money when loans are taken out.
2735 * Fixed problem with land units not being reported sunk after being sunk
2736 on a ship that was nuked or wastelanded in a sector.
2737 * Fixed problem with Spies.t using "llook" instead of "llookout".
2738 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
2739 on some Linux boxes.
2740 * Fixed problem with plague infection being way too high in cities when
2741 the BIG_CITY option is enabled.
2742 * Fixed bug in edit command getting confused with arguments.
2743 * Fixed bug in ask_move_in_off asking you to move in a negative number of
2744 troops (hey, it could happen. :) )
2745 * Fixed bug in add command not keeping flags or relations initially correct.
2746 * Fixed bug in torpedo command sometimes telling victim about torpedo
2747 sightings even when way out of range.
2748 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
2749 as not formatting them properly when reporting them.
2750 * Fixed bug in satellite with noisy transmission causing a potential
2751 crash of the server with non-100% efficient satellites.
2752 * Fixed potential crashing of the server during satellite display when not
2753 calculating distances to ships and units correctly.
2754 * Fixed bug where planes in non-allied sectors, ships and units could be
2756 * Fixed bug where planes on the trading block could be used on missions.
2757 * Fixed bug where planes and units that get traded don't have mobility set
2758 correctly when using MOB_ACCESS option.
2759 * Fixed bug which made security units virtually useless.
2760 * Fixed access times and mobility not being set right when building planes,
2761 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
2762 * Fixed minor formatting problem with launch of satellites.
2763 * Fixed minor formatting problem with planes with greater than 999 tech.
2764 * Fixed minor formatting problem with ships with greater than 999 tech.
2765 * Fixed problem with "llook" showing up in TOP info file.
2766 * Fixed problem with lwp Makefile choking on NT builds with clean target.
2767 * General cleanup of potentially ambiguous statements.
2769 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
2770 * Added "TECH_POP" as an option where technology costs more to make
2771 as your population grows past 50K civilians. It is disabled by
2773 * Changed "produce" command to accurately print what the true p.e. is.
2774 * Changed "update" command to display if mobility updating is enabled for
2776 * Fixed bug where toggling off the coastwatch flag also turned off
2777 forts firing on hostile ships coming into range.
2778 * Fixed bug where assaulting your own land would violate any treaties
2779 you have where assaults are a violation.
2780 * Fixed bug where all planes (even those without need for a crew, such
2781 as missiles) needed at least 1 military to build.
2782 * Fixed bug where when a ship sinks during the update due to lack of maint,
2783 land units and planes on it were left stranded.
2784 * Fixed bug where when a land unit dies during the update due to lack of
2785 maint, land units and planes on it were left stranded on it.
2786 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
2788 * Fixed bug in "show sector capabilities" not showing products correctly.
2789 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
2791 * Fixed bug in sectors that don't revolt not showing up as lost items.
2792 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
2793 * Fixed bug where MOB_ACCESS was not updating the mobility just before
2795 * Fixed bug in the way treaties are examined and sometimes produce
2797 * Fixed edit to allow creating negative mobility for sectors.
2798 * Fixed setsector to allow creating negative mobility for sectors.
2799 * Fixed bug where when writing out the value of a sector that had
2800 negative mobility and was damaged in combat, mobility was being
2802 * Fixed Taxes.t info page to reflect that captured civvies only pay
2804 * Fixed Technology.t info page to reflect TECH_POP option.
2805 * Fixed navigate.t info page to reflect that only ships in the fleet
2806 in the same sector that are fired upon have damage divided up.
2807 * Made techlists toggle on by default (so things are shown in order of
2808 technological advances.)
2810 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
2811 * Added optimization to increasing mobility to check if an object is
2812 already at max mob, just return since it can't be increased.
2813 * Added "-ltermcap" for client libs for hp build (it was already in
2815 * Added clearing of telegram flags after the update so that the next
2816 telegram is flagged as new and not part of the update.
2817 * Fixed Update-sequence.t to reflect MOB_ACCESS.
2818 * Fixed bug where fortification amount was not being limited to
2819 maximum mobility for land units (land_mob_max).
2820 * Fixed bug where land unit fortification strength was being calculated
2821 by using 127 instead of land_mob_max.
2822 * Fixed bug where scrapping land units was creating military.
2823 * Fixed description of sect_mob_neg_factor in econfig file.

2832 * Fixed potential bug in fixing up timestamp information when restarting a
2833 game with MOB_ACCESS turned on.
2834 * Fixed bug in explore command not setting mobility to correct
2835 value when MOB_ACCESS was enabled.
2836 * Fixed bug in enlist setting mobility incorrectly sometimes.
2837 * Added doc/backup file for deities which recommends how backups and
2838 restores of the data directory should be done.
2840 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999

2842 * Added NO_FORT_FIRE option which disables the ability of forts to
2844 * Added more error checking and recovery for corrupt data files.
2845 * Changed alphapos target to alpha-pthreads for better clarity.
2846 * Changed fairland to allow 0 sector distance to other islands and
2847 continents (James Risner)
2848 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
2849 match the way ships are described (since this is how they really work.)
2850 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
2851 and "fir" as the number of guns that a land unit fires.
2852 * Cleaned up misc. build warnings.
2853 * Changed artillery damage to be 5 + d6 per gun firing from just d6
2854 per gun firing and updated Damage.t to reflect this change.
2855 * Changed artillery firing ranges to be like ships ranges - divided
2856 by two, and modified them to make more sense.
2857 * Changed artillery units to be "slightly" :) more powerful.
2858 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
2859 * Changed "artillery" unit to tech 35.
2860 * Changed so that guns are no longer required to build units, and
2861 that guns must be loaded onto artillery units for them to fire.
2862 Client developers note: the show command has not changed yet to
2863 remove the 'guns' column (since guns are no longer required) but
2864 will in a future revision (possibly 4.2.4) so "be prepared" for
2865 "show land build" to change. :)
2866 * Fixed landunitgun to handle all the damage calculations like it should.
2867 * Fixed bug sinking planes when the ship they are on sinks.
2868 * Fixed bug destroying planes when the land unit they are on is destroyed.
2869 * Fixed bug where land units could fire support without enough military.

2873 * Fixed bug in determinig operations range of a ship.
2874 * Fixed bug in building planes where you could manufacture military.
2875 * Fixed warnings in threading package(s).

2879 * Fixed Ship-types.t to reflect the way things really work.
2880 * Fixed the way shutdowns work to hopefully better protect data files.
2881 * Fixed bug in attacking when sector mobility is less than 0 and it would
2882 prompt for attacking with a negative amount of military.
2883 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
2884 * Fixed bug in client when it prompts for country name it was putting
2885 an extraneous end of line on the end that needed to be stripped off.
2886 * Fixed problems running on Linux running on an Alpha machine. Thanks
2887 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
2888 on a machine to work out the bugs. (Note that the only build that
2889 works on Linux/Alpha is the linux-pthreads)
2891 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
2892 * Added some code optimizations into the update code when building paths.
2893 * Added some new cacheing for building paths to help speed up updates.
2894 * Added so that you can use "name" and "password" with the change command
2895 as well as "country" and "representative".
2896 * Added flag to power command so that if you are a deity and enter
2897 a negative number of countries you want to see, you see the power chart
2898 for that many countries without power numbers on the next line. Only
2899 useful for deities that want to see the chart un-broken up by that line.
2900 * Added new functionality to fortify command. You can now use a negative
2901 fortification value to cause the unit to be fortified and leave at
2902 least that much mobility on the unit. I.E. "fort * -67" will fortify
2903 all units and make sure the mobility of each unit doesn't go below
2904 67. If the mobility is already below that level (or equal) the unit
2906 * Added that the realm command prints "Realm #n is x:x,y:y" after
2907 you set a new realm.
2908 * Added TREATIES option and enabled it by default.
2909 * Added "no depth-charging subs" and "no new land units" treaty
2911 * Added Trannie Carter's basic client fix to use fgets instead of gets.
2912 * Changed market and command to only print the lowest priced lot of
2913 each given commodity by default. If you specify "all" it shows
2914 all lots on the market, and if you specify a specific item, it shows
2915 all lots of that item type.
2916 * Changed start command to only write out sector if it changed.
2917 * Changed stop command to only write out sector if it changed.
2918 * Changed how plane names were changed on server startup if the
2919 PLANENAMES option was enabled.
2920 * Changed move command to use standard askyn function for abandoning
2922 * Changed plane overlight sightings to take stealth into account,
2923 and if the planes managed to evade all flak and interceptors, they
2924 are not marked as "spotted" over enemy sectors.
2925 * Changed all units with the supply flag to have their marching speeds
2926 based on efficiency since that is their purpose. What this means is
2927 that supply units and trains are more effective at 100% than at 10%
2928 (just as fighting units are more effective at 100% than at 10%, but
2929 their effectiveness is determined by how well they fight, not how well
2930 they "run away, run away!" :) )
2931 * Changed so that flash toggle is on by default for POGO at setup
2933 * Changed so that when a sector is taken, all land units owned by the
2934 current owner are treated as planes are during takeovers (i.e. there
2935 is a pretty good chance they are blown up, and if not, they change owner
2936 to the attacker and are beat up pretty good.)
2937 * Fixed treaties to work again.
2938 * Fixed bug in taking over land units not using correct pointer (can
2939 cause a crash or data corruption.)
2940 * Fixed collect command to wipe deliver and distribution information
2942 * Fixed potential bug in bmap not working when destination bmap has
2944 * Fixed bug in shark command not getting right nation structure.
2945 * Fixed bug in server where empty commands (for example, all spaces
2946 or tabs) were being reported as bogus commands. They are now just
2948 * Fixed bug in scrap not dropping land units off of scrapped units carrying
2950 * Fixed bug in news where boarding of land units was reported backwards.
2951 * Fixed bug in calculating new people when growing them during an update.
2952 * Fixed missing -ltermcap in HP/UX build.
2953 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
2954 later and being reset to 0 anyway)
2955 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
2956 since that is what it really is.
2957 * Fixed retreat.t documentation to reflect the "retreat upon failed
2959 * Fixed bug where satellites were not orbiting the world during the
2961 * Fixed bug in torpedos being too smart. They knew how to jump over
2962 land! :) Now the "line_of_sight" routine is used to determine if a
2963 torpedo has a straight path to the destination. If it doesn't, the
2964 torpedo no longer jumps over land, but instead slams into it. This was
2965 an interesting bug because you could torp ships on the other side of
2966 a very skinny island as long as they were in range, even if there was
2967 no sea route possible.
2968 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
2969 units for example) but you still have to pick something to bomb. For
2970 ships it worked ok (just aborted that it couldn't find any more ships)
2971 and this was fixed for land units and planes.
2972 * Fixed server crashing bug when flying a plane and not carrying
2974 * Fixed bug in move losing commodities when it runs out of room in the
2975 destination sector. Goods are now attempted to be returned to the
2976 start sector, and apporpriate steps taken if the start sector is no
2978 * Fixed march to prompt you before you abandon a sector you own by
2979 marching out the last land unit.
2980 * Fixed check functions to only check the relevant portions of the structure
2981 and not the timestamp info that doesn't affect how the object functions.
2982 * Fixed bug in spy command that always told you if a spy unit was in a
2984 * Fixed bug in displaying of land unit missions not showing correct land
2986 * Fixed bug in wire command where new announcements that you read at
2987 the last second don't get wiped out properly.
2988 * Fixed bug where announcement file could be corrupted by very long lines.
2989 * Fixed bug where bmap was not set when player was told what kind of
2990 sector they were attacking (this was an old abusable bug that was
2991 removed long ago to fix the abuse, and it's been fixed in a non-abusable
2993 * Fixed bug where change command would warn you about monetary and
2994 BTU costs, but not prompt you to break out if you didn't want to really
2995 change your country name.
2996 * Fixed bug in sub-launched nukes that are intercepted being reported in
2997 the news incorrectly.
2998 * Fixed bug in load where you could abandon a sector and not know it by
2999 loading your last civilians or military onto a ship.
3000 * Fixed potential memory leak in autonav code.
3001 * Fixed potential bug where you could possibly determine if a sector is
3002 owned or not using one way plane missions.
3003 * Fixed Damage.t info page to properly show damages for planes and
3005 * Fixed deliver.t to include syntax for command.
3006 * Fixed country.t to include syntax for command.
3007 * Fixed bug where ships on orders were not adding radar information to
3008 the bmap during an update.
3009 * Fixed bug where ships on sail were not adding radar information to
3010 the bmap during an update.
3011 * Fixed bestownedpath code to use the bmap properly. Note this is a very
3012 important bug fix. When navigating a ship, players are no longer given
3013 free information that they would not normally know. For example, if you
3014 try sailing your ship off into uncharted areas of your bmap, the bestpath
3015 code will only use as much information as you have on-hand (i.e. your
3016 bmap) to plan out your path for you. If you have no information on an
3017 area, it just keeps forging on, until bumping into something. Of course,
3018 after the initial exploration through an area, the bmap will be set and
3019 used for all future sailings through that area. Harbors and bridges
3020 are still checked for construction worthiness if you know where they
3021 are (i.e. they are on your bmap.) (Overall, what happened before
3022 was that the bestpath code would route your ship around islands that
3023 you didn't even know were there, and you could use various commands
3024 to see how that ship was going to sail during the update and thus you
3025 gained information that you wouldn't normally know.)
3026 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
3027 and "BestAirPath" to use it properly. It is also good to note that
3028 bestownedpath is used to determine paths for ships and for planes,
3029 and that best_path (which uses the A* algorithm) is used for all land
3030 based paths, and that the two are never interchanged.
3031 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
3032 and RECON was never used before.)
3033 * Removed extraneous "resnoise" and "resbenefit" functions and combined
3034 the two for setresource and setsector commands.
3036 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
3037 * Fixed problem with global/plane.c not defining last structure element
3038 properly, and thus causing crashes when accessing certain plane
3039 routines. This happened during the move to make the PLANENAMES option
3040 run-time configurable.
3042 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
3043 * Bumped rev to 4.2.0 since this is a major release (the server is now
3044 run-time configurable for just about everything and is released under
3046 * Put in official licensing information.
3047 * Re-arranged and commented the econfig (Empire Configuration) file. The
3048 auto-generated "data/econfig" file is now pumped out chock full of
3049 comments (which may or may not be useful.) Since the server is
3050 pretty much fully run-time configurable (MAXNOC is not, but it gets
3051 a default of 99 anyway) deities will probably be spending more time
3053 * Added server support for building under NT, including mods from
3054 Doug Hay and Steve McClure to get the server building and running
3055 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
3057 * Added Doug Hay's ntthread.c implementation for NT threading.
3058 * Added max pop column to "show sector stats" output.
3059 * Added lboard command for boarding land units from sectors. Only raw
3060 mil can board land units, and only mil and land units aboard the unit
3061 being boarded fight back.
3062 * Added GODNEWS option. When enabled, the deity giving people stuff
3063 is shown in the news.
3064 * Added bridge tower sector ('@')
3065 * Added BRIDGETOWERS option. When enabled you can build bridge towers
3066 from a bridge span. You can then build bridge spans from the tower.
3067 If the tower is destroyed ( <20% eff) bridges connected fall unless
3068 supported on the other side. You can only build bridge towers in open
3069 water not adjacent to land and other towers. Expensive.
3070 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
3071 it is deity creatable only (can't redesignate unless you wasteland it
3073 * Changed "info all" to no longer use printdir, instead it just uses the "all"
3074 info page which contains this information.
3075 * Changed so you can now load up to 2 spy units onto non-land unit carrying
3076 submarines if the LANDSPIES option is enabled. Useful for sneaking up
3077 to shore and spying on your neighbors.
3078 * Changed so spies unloaded from ships are not given as gifts, they are just
3080 * Changed build command to handle building towers ("build t")
3081 * Changed show command to show tower stats ("show t b")
3082 * Changed reject so you can now reject things from any country except
3083 deity countries (this now includes sanctuary countries and visitor
3084 countries you don't want to deal with)
3085 * Changed ndump to dump nuclear stockpile ID as well.
3086 * Changed flash so that if someone allied to you is either not logged on or
3087 not accepting flashes, you are notified. This is info you could gain
3088 otherwise since you can see other countries that are allied to you via
3090 * Fixed bug in news command when HIDDEN mods are enabled.
3091 * Fixed distribute command to only write out to the database if we
3092 actually changed the sector (i.e. if we really moved the dist
3093 center, we write. Otherwise, it makes no point.)
3094 * Fixed threshold command to only write out to the database if
3095 we actually changed the sector (i.e. if we really changed the
3096 threshold, we write. Otherwise, it makes no point.)
3097 * Fixed - population growth and truncation in "Update-sequence.t" info
3099 * Fixed the way fortify takes mobility away from a land unit if
3100 engineers are present.
3101 * Fixed bug in buying commodities at the last minute not resetting the
3102 time correctly in all situations.
3103 * Fixed bug in building nukes where it would always ask if you tried
3104 building more than one at a time.
3105 * Fixed bug where if you put (either by building or by transporting)
3106 more than 127 of one type of nuke in a sector, they all got lost. A
3107 negative wrapover sort of thing.
3108 * Fixed ndump to print # of stockpiles dumped.
3109 * Fixed ndump.t to reflect changes
3110 * Fixed bug in build command that didn't account for EOL characters.
3111 * Fixed bug where you could use planes to drop conquered populace
3112 * Fixed bug in distribute command in how it checked for current distribution
3114 * Fixed pr_flash and pr_inform to no longer send messages if the player
3115 is still in the process of logging in (i.e. not in the PLAYING state)
3116 * Fixed report command output for deities.
3117 * Fixed bug in nuclear damage either taking out submarines when it
3118 shouldn't, or not taking them out when it should.
3119 * Fixed bug in loading units that are carrying units onto other units
3120 (note that it doesn't happen since only HEAVY units can carry other
3121 units and that check works, but that might change some day, and we
3122 don't want units carrying units to be carried by other units, etc. :) )
3123 * Fixed info pages to reflect new sector types.
3124 * Fixed info pages to reflect new spy unit capabilities.
3125 * Fixed show commands to only show trade ships if the TRADESHIPS option
3127 * Fixed build command to only allow building of trade ships if the
3128 TRADESHIPS options is enabled.
3129 * Fixed up some definitions located in many places used for checking
3130 sectors for navigation rights.
3131 * Fixed power.t to correctly describe NEW_POWER formula.
3132 * Made HIDDEN option run time configurable.
3133 * Made LOSE_CONTACT option run time configurable.
3134 * Made ORBIT option run time configurable.
3135 * Made SAIL option run time configurable.
3136 * Made MOB_ACCESS option run time configurable.
3137 * Made FALLOUT option run time configurable.
3138 * Made SLOW_WAR option run time configurable.
3139 * Made SNEAK_ATTACK option run time configurable.
3140 * Made WORLD_X and WORLD_Y run time configurable.
3141 * Made MARKET option run time configurable.
3142 * Made LOANS option run time configurable.
3143 * Made BIG_CITY option run time configurable.
3144 * Made TRADESHIPS option run time configurable.
3145 * Made SHIPNAMES option run time configurable.
3146 * Made DEMANDUPDATE option run time configurable.
3147 * Made UPDATESCHED option run time configurable.
3148 * Made LANDSPIES option run time configurable.
3149 * Made NONUKES option run time configurable.
3150 * Made PLANENAMES option run time configurable.
3151 * Removed SMALL_SERVER stuff (unused baggage)
3152 * Removed trading post sector ('v')
3154 Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
3155 * Fixed bug in aircombat where planes in flight could intercept air
3156 defense planes and take no damage (i.e. they got to fight twice,
3158 * Fixed bug in freeing memory after performing missions that could crash
3159 the server (it mainly happened after an interdiction mission using
3160 planes and escorts, where some escorts came from airports that didn't have
3161 bombers going up. Freeing the leftover escorts was crashing the server.)
3162 * Fixed bug where you could load non-existant units if you were allied
3164 * Fixed bug where you could pin-bomb a plane with itself.
3165 * Fixed bug where satellites over a bridge may get killed if the bridge
3167 * Fixed bug where land units on a ship in the same sector as a bridge
3168 that is splashed may get sunk.
3169 * Fixed bug where planes on a ship in the same sector as a bridge
3170 that is splashed may get sunk.
3171 * Fixed doconfig with correct empire site text.
3172 * Fixed major problem with abms not firing, and sometimes crashing
3174 * Fixed bug in land units counting up loaded units wrong.
3175 * Fixed doconfig makefile to have doconfig.c as a dependency.
3176 * Fixed bug in resetting commodities (the comm_uid was not being
3178 * Fixed bug in repaying loans not working correctly (the l_uid was not
3179 being properly set.)
3180 * Fixed bug in buying items from the trading block not allowing you
3181 to due to a perceived change in item status.
3182 * Fixed bug in mfir.c where a bogus input to a target could crash
3184 * Fixed bug that after you read telegrams new telegrams may not send
3185 an inform message (the old telegram flags were not cleared.)
3186 * Fixed bug where fort support distance calculations are calculated
3187 twice instead of just once. This bug caused a lower percentage
3188 of support fire than designed.
3189 * Fixed bomb.t to reflect land unit changes.
3190 * Put in some integrity checking for planes returing from bombing runs.
3191 * Added ability to edit land unit that a land unit is loaded on in
3193 * Consolidated bridgefall code into "knockdown" function (this code
3194 existed in at least 3 places, and was different in all of them.)
3195 * Subs returning fire are no longer reported in the news.
3196 * Visitor countries can now use the 'motd' command.
3197 * When trying to use a visitor country, if it is in use, you are not told
3198 by whom, just that it is in use.
3199 * Optimized (slightly) support fire from forts not getting supply and
3200 shells if not needed (out of range)
3201 * Updated Education.t
3202 * Modified (increased) chances of hitting mines slightly.
3203 * Removed unused variables from shp_check_mines.
3205 Changes to Empire 4.0.17 - Fri Jul 31 06:12:21 PDT 1998
3206 * Added ability in edit to change coastal flag for sectors.
3207 * Added ability in edit to edit plague values for ships.
3208 * Added ability for "spy" to report all units/planes not owned by you
3209 that exist in the sector you are spying from.
3210 * Modified naval planes and anti-sub planes.
3211 * Changed so that missiles and bombs that miss their targets cause
3212 collateral damage in the target sector (they have to land somewhere!)
3213 * Changed llook so that non-spy units are required to have at least 1
3214 military personnel on board to see anything.
3215 * Fixed "llookout.t" to reflect change for military requirement.
3218 * Added "lmine" flag for deities to see what sectors have mines in them
3219 (works for sea and land mines, used "lmine" to distinguish it from "min"
3220 which determines mineral (iron) content of a sector.)
3221 * No longer able to pin bomb land units on a ship.
3222 * Land units are required to have at least one military loaded to perform
3224 * Firing land units are required to have at least on military loaded to
3225 be able to fire (or return fire.)
3226 * Spies are not always seen when being pinbombed. You have to look very
3227 carefully for them (as you usually would.)
3228 * Fixed typo in "Spies.t"
3229 * Added new info about spy ability to spy.t.
3230 * Updated tax information in Innards.t and Update-sequence.t
3231 * Fixed typo in fire.t information about units firing on ships.
3232 * Loading military onto land units now resets fortification. (You gotta
3233 re-fortify the new guys.)
3234 * Fixed bug where planes that were mine capable could not drop mines if
3235 they were not cargo capable.
3236 * Fixed bug in potentially crashing in update code for nations tech/research.
3237 * Fixed bug in execute putting you into execute mode incorrectly.
3238 * Fixed bug in board not allowing land units to board from 0 mobility
3240 * Fixed bug where interdicted land units that were missed displayed
3241 a "SPLASH! Bombs miss your ships" message.
3242 * Fixed bug in minesweeping sectors where, even with mobility or
3243 having the sweep ability, ships would get hit by mines for doing
3245 * Fixed bug in count_land_planes always writing out land units unnecessarily.
3246 * Fixed bug in count_planes always writing out ships unnecessarily.
3247 * Fixed bug in lnd_count_units always writing out land units unnecessarily.
3248 * Fixed bug in count_units always writing out ships unnecessarily.
3249 * Fixed bug in llook that reported units on ships.
3250 * Fixed bug in llook that reported satellites launched over the unit.
3251 * Fixed bug in llook that always reported spies (it should be a 10-100%
3253 * Fixed bug in anti possibly not saving lost items correctly.
3254 * Fixed bug in planes getting extended range when on missions and the
3255 op center is not where the plane is located.
3256 * Fixed bug in land unit defensive strength not being based on the eff of
3257 the unit when calculating odds of a battle.
3258 * Fixed bug in board not reporting consistant information.
3259 * Fixed bug in the way land unit casualties were being taken.
3260 * Fixed bug where land units on ships could return fire.
3261 * Fixed bug where land units on other land units could return fire.
3262 * Fixed bug where land units on other land units could fire.
3263 * Fixed bug in attacks/assaults/boardings spreading plague incorrectly.
3264 * Fixed bug in updating plague for ships.
3265 * Fixed bug in updating plague for land units.
3266 * Fixed bug in updating plague for attacking/defending land units.
3267 * Fixed bug where you couldn't pin-bomb land units that were < 20% eff.
3268 * Fixed bug which revealed the owner of torping subs when on a mission.
3270 Changes to Empire 4.0.16 - Fri Jun 12 08:52:06 EDT 1998
3271 * Added patches sent in by Steve McClure, Sverker Wiberg and Curtis
3272 Larsen. They are described with other changes below.
3273 * Fixed bugs in the following commands that allowed two cooperating
3274 countries to create infinite numbers of any commodity and/or cash
3275 at any time (race conditions in the server): build, board, deliver,
3276 designate, distribute, explore, fuel, improve, load, ltend, mobquota,
3277 move, name, order, reset, sail, sell, set, tend, territory, test,
3278 threshold, torpedo, transport, unload
3279 * Fixed bug in board command giving out too much information about a
3280 non-owned sector when it shouldn't be.
3281 * Fixed bug in board command when firing on a sector in defense before
3283 * Fixed bug in rangeedit allowing plane(s) to possibly be stored wrong.
3284 * Fixed bug in launch allowing plane to possibly be stored wrong after
3286 * Fixed bug in lrangeedit allowing land unit(s) to possibly be stored wrong.
3287 * Fixed bug in morale allowing land unit(s) to possibly be stored wrong.
3288 * Fixed bug in arm/disarm allowing a plane to possibly be stored wrong.
3289 * Fixed bug in loan sometimes not writing database correctly.
3290 * Fixed bug in collect.
3291 * Fixed bug in dropping mines from land units.
3292 * Fixed crashing bug in sector_strength routine when oceans take
3294 * Fixed bug in transport possibly decrementing too much mobility when
3296 * Fixed some little warning type messages building with gcc -Wall.
3297 * Fixed problem compiling lwp threads with glibc6 under Linux.
3298 * Changed flash so that players can always flash deities.
3299 * Changed players command to always show deities and visitor countries
3300 that are logged on, and only show allied countries for normal player
3302 * Fixed bug in anti command not stopping sectors when they revolt.
3303 * Fixed bug in set_coastal function not counting bridge spans as
3304 water based sectors (after all, the land is still a coastal sector,
3305 even if next to a bridge span.)
3306 * "flash" and "players" is re-enabled for visitor accounts.
3307 * Fixed bug in bleeding of technology and research to other players.
3308 * Fixed bug in explore not spreading plague correctly.
3309 * Fixed bug in move not spreading plague correctly.
3310 * Fixed bug in deliver not spreading plague correctly.
3311 * Fixed bug in distribute not spreading plague.
3312 * Included "postresults" script in the scripts directory which can be
3313 used to auto-post daily power chart/announcements to rec.games.empire.
3316 * Removed OVCONFIG from build.conf, and patched doconfig to match.
3317 * doconfig is only run if needed
3318 * emp_client and emp_server are only linked if needed
3319 * Added list of disabled options to the version command.
3320 * Fixed bug in survey allowing you to see hidden variables.
3321 * Re-enabled escort missions due to above bug fix most likely the problem.
3322 * Changed one instance of "restrict" to "restricted" in bestpath.c. For
3323 some reason, this was causing a problem on one of the Linux builds (??).
3324 * Added "show sector capabilities" functionality (this didn't exist
3326 * Fixed bug in neweff not reporting stopped sectors. It now (correctly)
3327 reports them as not changing eff.
3329 Changes to Empire 4.0.15 - Wed May 20 12:35:53 EDT 1998
3330 * Fixed the spelling of Markus' name in CHANGES4.0 files.
3331 * Added Markus' patches/fixes. Some are detailed below.
3332 * Added 'mipsultrix.gxx' build target.
3333 * Fixed doconfig to write ipglob.c in the correct target area.
3334 * Fixed a bunch of type casting that needed to be done correctly.
3335 * Only print out last connect by for non-visitor accounts.
3336 * 'players' command is only useable by non-visitor accounts.
3337 * Fixed ask_off in attsub.c to not print out allied sector mil counts

3350 Changes to Empire 4.0.14 - Wed Apr 8 08:47:54 EDT 1998
3351 * Fixed time_t problem in common/log.c
3352 * Fixed bug in headlines
3353 * Replaced vaxultrix build flags with proper vanilla ones.
3354 * Fixed bug in update/prepare.c (sometimes not getting charged for
3355 mil on units and ships)
3356 * Fixed bug in printing of "No ship(s)" twice in cargo command when no
3357 ships were selected.
3358 * Temporarily disabled escort missions until a fix is found. They are
3359 randomly crashing the server.
3360 * Fixed morale.t to reflect that retreat percentage is based off of
3361 morale_base and not 75.
3362 * Fixed bug in bridgefall where planes and units on ship in a sector
3363 that has a bridge collapse are being sunk.
3364 * Fixed bug in update/produce.c when a sector overflows it's capacity
3366 * Fixed bug in produce command reporting incorrect costs (sometimes).
3367 * Land units on ships will now try to draw supply from the ship they
3370 Changes to Empire 4.0.13 - Mon Mar 2 11:04:28 EST 1998
3371 * Fixed bug in distribute when world sizes are other than 64x32
3372 * Fixed bug in getcommand (not really a bug, just made it work like
3373 it used to so that the players command is useful for deities
3375 * Fixed building of POSIX threads on Alpha running Digital Unix.
3376 * Fixed line_of_sight prototype in sona.c
3377 * Fixed fairland not to conuse stupid C++ compilers.
3379 Changes to Empire 4.0.12 - Tue Feb 24 11:27:31 EST 1998
3380 * Fixed client build on linux (whoops)
3382 Changes to Empire 4.0.11 - Tue Feb 10 10:53:10 EST 1998
3383 * AIX build seems to only work with gcc right now (but at least that works)
3384 * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box.
3385 * Took out autosupply of airports when bombing or dropping shells.
3386 (This was the only commodity this was done for, and it was creating
3387 problems since supply is still somewhat broken somewhere)
3388 * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
3389 submitted patches, which collectively included cleaning up most
3390 of the server prototypes and bogus declarations. Many thanks.
3391 * Increased incoming command buffer to 1024 from 512 bytes
3392 * Increased the # of parsed arguments from 64 to 100
3393 * Fixed bug where spies were not dying when damaged.
3394 * Fixed bug in HIDDEN mods in declare command not printing country # of
3395 uncontacted country correctly (or at all as a matter of fact)
3397 Changes to Empire 4.0.10 - Mon Aug 18 12:34:58 EDT 1997
3398 * Fixed bug where fleets were being interdicted but the damage was being
3399 spread to ships not in the same sectors.
3400 * Fixed but in market when buying goods without enough cash.
3401 * Planes in orbit over airports are no longer fixed up during updates.
3402 * Planes in orbit are no longer damaged when the sectors they are over
3404 * Planes on ships are no longer damaged when the sectors they are in are
3405 damaged, unless the ship is damaged.
3406 * Fixed problem with no newline after partisan activity telegram in
3408 * Fixed problem in chan.c printing out change costs incorrectly.
3409 * Fixed problem in dispatch.c screwing things up on redirection.
3410 * financial should now handle 6 and 7 digit loans.
3411 * Planes on ships that are in sectors that revolt are no longer taken
3413 * Fixed bug in powe.c where the power report was mis-calculating the
3414 efficiency of planes.
3415 * Fixed doconfig.c to use STDC instead of multi-level #ifdefs.
3416 * Fixed bug in parse.c that was screwing up double quotes in conditional
3418 * Military in a sector now only produce up to maxpop, just like civvies
3419 and uw's. No more stuffing 6K mil into a mountain to max it out. You
3420 can still hold more mil there over the updates, but the extras just
3421 won't produce anymore.
3422 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
3424 * Fixed bug in day of week calculation for server up time in common/keyword.c
3425 that is used for gamedays.
3426 * Documented what happens to standing military in collect.t when you collect
3428 * Documented mountains only holding and using 1/10th of the normal sector
3429 population in Sector-types.t.
3430 * Fixed documentation on ship's firing ranges in fire.t to be less
3432 * Updated nukes in nuke.t
3433 * Added apropos command (thanks to Mike Wise)
3434 * Added case-insensitivity to the info command (thanks to Mike Wise). If
3435 there are two files of the same name, and you don't get a complete match,
3436 then whichever file is found first in the directory is used.
3437 * Changed documentation in wantupd.h
3439 Changes to Empire 4.0.9 - Sat Apr 19 23:01:51 EDT 1997
3440 * Fixed dump info pages that were getting formatted funny.
3441 * Fixed improve info page.
3442 * Fixed bug in allied planes/units not moving when the carriers move.

3446 * Fixed bug in harden not printing correct values.
3447 * Fixed bug in creating/moving/etc. nuclear stockpiles.
3448 * Fixed bug where subs were trying to torp commodities moving on land when
3449 on interdiction. (This was funny ;-) )
3450 * Fixed bug in "move" where you could keep a sector even after someone else
3452 * Budget now correctly reports the # of units being built.
3453 * Mil on units & ships are now reported as normal military costs, not
3454 ship or unit maintainence costs in budget.
3455 * Fixed bug in update code where taxes could potentially be initialized
3456 incorrectly (affected budgets too.)
3457 * Fixed bug in nat.h header so that it uses SCT_MAXDEF instead of a fixed
3458 number (that was incorrect.)
3459 * Fixed bug with trains - they needed the xlight flag to carry planes.
3460 * Revamped and improved flak.
3461 * Added "Flak" info page.
3462 * Added "Fallout" info page.
3463 * Fixed repay/offer/consider to all need a capital to be used.
3464 * Fixed bug with air defense missions not running when not AT WAR. They now
3466 * plane/ship/unit short names are all now 4 characters, padded if needed.
3467 * pdump/sdump/ldump/ndump now just print the short name for the type.
3468 * sdump now has ship name at very end in quotes.
3469 These were done at the request of some client developers for ease of use.
3470 * Fixed extra space in the dump output.
3471 * Fixed fallout - not quite so nasty anymore.
3472 * Fixed fallout - things on ships/units are damaged now.
3473 * Fixed and balanced planes/ships/units/nukes in conjunction with each other.
3474 * Fixed bug in doconfig.c calculating wrong s_p_etu sometimes.
3475 * Fixed bug where harbors weren't being used to resupply.
3476 * Fixed bug where selling units loaded with planes and units wouldn't take
3477 the loaded planes or units - they are now dropped.
3478 * Fixed bug in arm/disarm where you could arm/disarm planes on the trading
3480 * Deities can now remove things from the trading block/market.
3481 * Fixed bug in "work" not charging engineers enough mob.
3482 * Fixed bug in "work" not adding teardown and buildup avail costs together.
3483 * Subs no longer need mobility to return fire when fired upon.
3485 * Fixed bug in "trade" allowing 2 players to pay for the same item, but only
3486 the last player gets it.
3487 * Fixed bug where you couldn't launch missiles from allied ships or sectors.
3488 * Fixed bombing so that pin-bombing can cause collateral damage too.
3489 * Fixed sector damage to damage planes there too.
3490 * Fixed flag in lload so that it doesn't always print if not needed.
3491 * Fixed "sell.t" info page.
3492 * Fixed bug in "buy" where not entering the price correctly could cause
3494 * Fixed "sell" so that at least 1 mobility is required to sell goods. Keeps
3495 the midnight "raid and sell" abuse down. :)
3496 * Fixed "show plane cap" to move the last column over 1 more where it should
3498 * Fixed timestamps to be updated for units/planes on ships/units that move,
3499 since those units/planes move too.
3501 Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
3502 * Fixed bug in nstr_exec that was wiping out the previous conditional.
3503 This was major because it affected timestamp values which are more
3505 * Fixed bug in sdump.c for typo in reporting the trade ships origin.
3507 Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
3508 * Fixed bug in aircombat.c when calculating the air combat odds. Negative
3509 numbers were screwing things up good...
3510 * Fort sector's coordinates are no longer printed when auto-firing at
3512 * Subs can now surface and fire deck guns (again) They can also be
3513 hit by return fire when doing so.
3514 * Fixed bug in setting of plane attack and defensive values so that
3515 negative numbers don't keep going further negative.
3516 * Fixed incorrect military control calculation in the sell command.
3517 * Trading posts are no longer required to sell goods from. You can sell
3518 from harbors and warehouses now too.
3519 * Spy now prints out the owner of land units you see when spying. Before
3520 this was assumed to be sector owner, which is no longer true.
3521 * Loading land units now prints out what was loaded onto each unit,
3522 just as loading ships do.
3523 * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output.
3524 * Added "GO_RENEW" option. This option means that gold and oil resources
3526 * Added "lost_items_timeout" config variable, and set the default to
3527 48 hours. This determines how long lost items stay in the lost items
3529 * Fixed land unit names to be more consistent.
3530 * Fixed mission.t info page.
3531 * Fixed bug in that if mission_mob_cost was set to 0, even negative
3532 mob units should be able to be put on missions.
3533 * Removed restriction on things needing to be at least 60% to be put
3534 on a mission. Note that while you can put them on missions at < 60%
3535 now, when trying to do the mission, it still checks the eff. This
3536 is to help in automatic setup (build, put on mission, forget) instead
3537 of having to come back repeatedly.
3538 * Spies caught in Neutral or Friendly countries cause the Neutral or
3539 Friendly country to go Hostile towards the owner of the spy.
3540 * Tweaked ammunition numbers for artillery units.
3541 * No more automatic declarations of War should be made. You will go
3542 hostile, but since going to war doesn't increase your countries
3543 defenses, and is purely political, it is left to the player to go
3545 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
3546 * Fixed bug in "lmine" that was crashing the server if the land unit was
3548 * Fixed buy so that if you specify a product, you can only bid on that
3550 * Added "lost.t" info page.
3551 * Added "lost items" database (EF_LOST)
3552 * Fixed bug where you could move in allied forces after an attack if they
3553 bordered the victim area.
3554 * Fixed nstr_comp to deal with values > 16 bits coming in from
3555 client for comparisons.
3556 * Changed last minute market/trade timers to increment 5 minutes. 2 minutes
3558 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
3559 * Commented out the logging of the market checking in server/marketup.c,
3560 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
3561 pretty much useless data that made parsing the server.log file more
3562 more difficult than it needed to be.
3563 * Fixed crashing bug in ldump.
3564 * sdump, ldump, ndump, pdump and dump now print out the current
3565 timestamp on the "DUMP XXX" line.
3566 * Fixed denial of service bug in lib/player/accept.c in
3567 player_find_other function.
3568 * Fixed bug in shark reporting incorrect buyer of the loan.
3569 * Fixed bug in sdump.c (case 0 should have been case 10)
3570 * ldump and sdump now always print the fuel column if asked for,
3571 even if opt_FUEL is turned off. In the case that it is turned
3572 off, the fuel is listed as 0.
3573 * Added "timestamp" field, which is updated every time an item is
3575 * Fixed up the Clients.t info page.
3576 * sdump now prints trade ship building origin.
3577 * sdump now always prints name even if SHIPNAMES isn't defined. If
3578 it is not defined, then the name is empty.
3579 * Added "timestamp" to info/Concepts/Selector.t
3580 * Added some more relevant info to info/Server/Empire4.t
3581 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
3582 is no longer torn down when a sector is re-designated.
3583 * Fixed sell.t to more accurately reflect the time-delay market.
3584 * Fixed read.t and wire.t to reference accept and reject.
3585 * Fixed reject.t not referencing accept command.
3586 * Fixed collect.t to more accurately reflect what goes on when collecting
3588 * Fixed financial.t to reflect defaulted loans.
3589 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
3591 * Fixed "census.t" (had incorrect reference to "info syntax" instead
3594 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
3595 * Increased damage from depthcharges because on increased damage from
3596 torpedos. Sub frange decreased to be more balanced with destroyer frange.
3597 * Intelligence reports (spy) on units will now report the estimated number
3599 * Fixed equation for ship visibility so it will drop as tech increases.
3600 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
3601 land units, planes, and nukes.
3602 * If fields are provided, dump will only supply those fields requested.
3603 * Decreased speed of subs.
3604 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
3605 required for infrastructure improvements.
3606 * Units that lose an assault or a boarding attempt from a ship will no
3607 longer swim back to the ship they came from.
3608 * Units that take extra casualties will no longer lose all their mil at
3610 * Infrastucture is retained when redesignating a sector.
3611 * Dieing spies will no longer crash the server.
3612 * Units, planes, and ships must have mobility to perform missions.
3613 * Units on ship being scrapped are transferred to harbor.
3614 * Food is no longer autoloaded onto units when they are built.
3615 * Fixed show plane stat to show correct range.
3616 * Infantries now take damage at same rate as casualties.
3617 * Fixed bug with hap_fact. Having more happiness now helps with fighting
3619 * Fixed anti to write back target country so che will continue to fight
3621 * Fixed llookout to show correct estimate on number of mil on unit.
3622 * Added buildable architecture "hp". This type will build the server on
3623 a HP/UX machine using the standard compiler instead of gcc.
3625 Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
3626 * Fixed bug in update/distribute.c where pathcost was not being called with
3627 the MOB_ROAD argument (and thus distribution costs could be GREATLY
3628 affected.) - Thanks Ice!
3630 Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996
3631 * Fixed Solaris port using gcc.
3632 * Fixed doconfig.c to create directories with right modes.
3633 * Fixed install macros in makefiles to move binaries to the right
3636 Changes to Empire 4.0.3 - Wed Dec 4 22:46:53 EST 1996
3638 * Fixed doconfig.c (put exit(0) at the end of main.)
3639 * Fixed improve.c (moved the prompt[] string outside the fcn.)
3641 Changes to Empire 4.0.2 - Mon Oct 14 12:26:40 EDT 1996
3642 * Put in LND_MINMOBCOST in land.h
3643 * Put in change in lnd_mobcost in lndsub.c
3644 * Put in new nuke costs in nuke.c
3645 * Put in fix so that total work can only be done by the max pop. No more extra
3646 civvies tossed in will do it anymore in human.c.
3647 * Put in fix for src/util/Makefile - beefed it up.
3648 * Put in fix to show where your ship is when it gets shelled in mfir.c.
3649 * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in
3651 * Fixed Update-sequence.t.
3652 * Put in fix for mobcost bonus for 0% highways.
3655 * Spruced up torpedo damage somewhat. :) :)
3656 * Fixed "assault bmap bug" in attsub.c
3657 * Fixed Produce.t (bars cost)
3658 * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
3662 * Fixed "offer" and "consider" not being legal commands in player/empmod.c
3665 * Fixed lstat.c, pstat.c and sstat.c
3666 * Fixed cutoff command in cuto.c
3667 * Fixed attack value in attack_val in lndsub.c
3668 * Fixed lload in commands/load.c
3669 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
3670 always fight until dead or retreating. 0 makes them get stuck.
3671 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
3672 else for that matter.)
3673 * Fixed llook in commands/look.c
3674 * Fixed che bug in subs/nstr.c
3675 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
3676 of people would starve.)
3677 * Fixed update/human.c - feed_people rounding problems (I hope.)
3678 * Fixed morale problem in update/land.c
3679 * Fixed count_bodies in attsub.c
3680 * Fixed lnd_mobcost.
3681 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
3682 * Fixed interest rate in commands/offe.c
3683 * Fixed bug in buy.c.
3684 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
3685 infrastructure. When off, the defensive infrastructure is the same
3686 as the sector efficiency, and you can't improve it. This is OFF by
3690 * Land units are now built with a default reaction radius of 0.
3691 * Changed name of lt artilleries to "lat" from "lart" so you can now build
3693 * Lowered the speed and firing range of pt boats.
3694 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
3696 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
3697 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
3698 1.5 * ETU_RATE for ships.)
3699 * Conquered civvies only pay 1/4 taxes.
3700 * Railways don't get torn down when you rebuild sectors anymore (but roads
3701 and defenses do (if enabled.)
3703 Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
3704 * Added "extern double tradetax" to check_trade in trad.c
3705 * Improved description of data directory in build.conf
3706 * Fixed bug in attacking land units that retreat so they now get
3707 charged mobility for attacking.
3708 * Fixed dump to report road, rail and defense of a sector at the end.
3709 * Fixed doconfig bug in not checking the right directory to see if the
3710 "data" directory existed or not before trying to create it.
3711 * "change" now works for sanctuary countries.
3712 * Fixed the description of "sinfrastructure".
3713 * Added more info to "Infrastructure".
3714 * Units/planes are no longer reduced to 75% when bought from the trading
3716 * Supply units were slowed down to the speed of infantry units.
3717 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
3718 * Bars interest is up to $250 per 1K again.
3719 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
3720 * Fixed various info pages.
3721 * Fixed bug in people not getting truncated when broke (this was thought
3722 to be fixed, but wasn't. Now it is, dammit!)
3723 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
3724 * Market/trade taxes and trade ship payoff figures were added to version.
3725 * "cede" has been removed as a default command.
3726 * Makefile rule was fixed for depend build.
3727 * Fixed bug in mapdist not taking world edges into account nicely enough.
3728 * Added a "scuttle" order for autoscuttling trade ships. Makes using them
3729 easier. Cleaned up scuttle code while in there.
3730 * Fixed bug with scuttling a ship with units on it not scuttling the units
3733 Changes to Empire 4.0.0 - Wed Aug 21 1996
3734 * Initial Wolfpack release - Long live the Wolfpack!!!!
3735 * Cleaned up the build environment. Now all that is needed is to edit the
3736 build.conf file, answer the questions there and type "make <arch>" to
3737 build for a specific architecture. Thus, no more reliance on gnumake
3738 or special shell scripts.
3739 * We are now shipping the pre-built info pages with the server for those who
3740 Don't want to build them. You can also still just type "make" and have
3741 the info pages build, but it doesn't completely work (i.e. rebuild new
3742 Subjects) if you don't have perl5 installed.
3743 * Put in the "help" command that does the same thing as "info".
3744 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
3745 wish to support it. 2) We envision a better scheme for doing similar
3746 things will come along.
3747 * Put in MOB_ACCESS - This allows real-time updating of mobility.
3748 * Put in MARKET - This is the time-based market (yes, still teleports,
3749 but it's not as bad as it was.)
3750 * Lots of the documenation has been updated, but there is more to do.
3751 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
3752 enabled, you don't need any of that type of material to build things.
3753 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
3754 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
3755 any materials to build a bridge.
3756 * There is no mobility cost for assigning missions. But, there is also
3757 no longer any benefit for being on a mission either.
3758 * Damage is the same for all commodities (people too.) This means you
3759 can deity shell/bomb sectors again.
3760 * Units are now dependant on tech. What this means is that their statistics
3761 now increase with tech. In addition, there is only 1 type of each basic
3762 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
3763 This reflects the idea that as you learn more, you learn how to not only
3764 build better units, but you learn to build units better. :) This also
3765 opens the door for a "lupgrade" command along the same lines as the
3766 "upgrade" command for ships.
3767 * Units now have a minimum mob cost for attacking a sector. Marching
3768 mob costs have not changed.
3769 * Starting units have been removed. This means that at the beginning, people
3770 may live a little longer since their neighbor can't come visiting quite
3772 * Shells are no longer required to build units.
3773 * Mil are no longer required to build units.
3774 * Mil are no longer an intrinsic part of a unit. They are now a loadable
3775 commodity. The way a unit's defense/att bonuses work now are
3776 attack = (att * mil * eff)
3777 defense = (def * mil * eff)
3778 In addition, when a unit takes damage, both the eff and the mil go
3779 down. You can quickly toss in new hacks, but you need to wait to repair
3780 the unit at the update. Thus, you can now look at unit's efficiency
3782 * You need at least 1 mil on a unit to march it (spies are the exception.)
3783 * Units always react if in range and they have the mobility, no matter
3784 what their efficency.
3785 * Units may now march anywhere - in your own sectors, deity owned sectors
3786 or allied sectors, with 1 exception, spies. Also, your units can get
3787 trapped if your ally declares non-alliance with you while your units
3788 are still in his country.)
3789 * Units always march at their speed, efficiency doesn't matter.
3790 * LANDSPIES was added - This creates land unit based spies. Spies may march
3791 anywhere, with a chance of getting caught (except in allied territory.)
3792 See "info Spies" for more info on them.
3793 * Planes may now be based out of allied airports. Landing planes on
3794 ships/sectors you do not own no longer changes thier owner. You can only
3795 land on owned/allied sectors/ships, and you may only
3796 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
3797 you are allied with goes hostile at you, your planes are now stuck there.
3798 Note that if you are using an allied airport, their commodities get
3799 sucked up, not yours (obviously.)
3800 * Planes are now tech-based. Their statistics increase as their tech
3801 increases. Deleted extraneous planes.
3802 * There is a new toggle, "techlists", which allows you to see what you
3803 can build/stats/capabilities sorted by tech instead of groupings.
3804 * Ships are now tech-based. Their statistics increase as their tech
3805 increases. Deleted extraneous ships.
3806 * Che can now be lessened by making happiness. If you have more happiness
3807 than your conquered populace, they don't fight as hard or recruit as
3808 much. If you have less than them, they fight harder and recruit more.
3809 It's not much though - it ranges from 2.0 in your favor to only 0.8
3810 against you (whereas it was always 1.0 before.) So, it definitely
3811 favors the attackers to make lots of happy now.
3812 * Bridgeheads can only be built on coasts.
3813 * Players command was fixed so you only see allies, and don't get
3814 approx #'s of players anymore.
3815 * POSIX threads support has been added.
3816 * The attack bmap bug has been fixed.
3817 * BTUs regenerate 3 times faster now.
3818 * GRAB_THINGS is off by default.
3819 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
3820 as a default (you couldn't make wasteland before with FALLOUT, now
3822 * You can now deliver military and civilians.
3823 * Added SHIP_DECAY option - off by default (turns off ships decaying out
3824 at sea if not enough mil.)
3825 * The reverting owner bug has been fixed in territory, thresh, dist
3826 and deliver. There are probably more, and when found, will be fixed.
3827 * The "sectors don't starve when stopped or broke" bug has been fixed.
3828 * The "people never get truncated" bug has been fixed.
3829 * Added infrastructure to sectors. What this means is that a sector
3830 can now have it's mobility improved by building both roads and
3831 railways. It also means that a sectors defense is now based on the
3832 defensive infrastructure you build into the sector (no more intrinsic
3833 better defenses based on the sector, you determine which sectors are
3834 defended heavily, and which aren't.)
3835 * The defensive value of a sector no longer relies on the efficiency of
3836 the sector. Instead, it relies on the defensive efficiency of the sector.
3837 Thus, the "production" and "defensive" aspects of sectors have been
3839 * "show sect stats" now shows the maximum defensive value for sectors.
3840 * Changed sector structure to take floats for off/def values so we can use
3841 a base of 1 instead of 2.
3842 * Added "improve" and "sinfrastructure" to support the infrastructure
3844 * Added L_TRAIN units which can only travel along railways. Very fast on
3845 efficient railways, slow on non-efficient ones.
3846 * Added the ability for units to carry other units.
3847 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
3848 * Forts only cost $500 to build and 100 hcms now (since they don't get any
3849 better defenses automagically.)
3850 * Modified "show sect build" to show the costs for building up the
3851 infrastructure of a sector.
3852 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
3853 spyplanes too) to show the new infrastructure stuff, rounded of course.
3854 * Added Drake's info->html scripts, with some modifications, so you can
3855 now type "make html" and have your info pages built as html files too.
3856 This adds a new directory, "info.html", to the build tree.
3857 * Modified upgrade so that planes and land units may now be upgraded.
3858 * Added pstat command to list the statistics of your planes.
3859 * Added lstat command to list the statistics of your land units.
3860 * Added sstat command to list the statistics of your ships.
3861 * Added nmap command to show a map of your sectors after their new
3862 designations have taken place.
