1 Changes to Empire 4.3.28 - Sat Jul 16 11:30:53 UTC 2011
2 * Don't let POGO (#0) navigate dead ships, and march dead land units.
3 The ghosts even got sighted and interdicted, and could hit mines.
4 Has always been that way.
5 * llook can't see land units and planes loaded on land units anymore.
6 * Fix board to ignore land units loaded on land units when testing
7 whether a sector can board. Broken in 4.0.17.
8 * Fix transport to reject planes loaded on land units. The plane
9 remained on its carrier. When the land unit moved, the plane was
10 teleported right back to it. Broken since Chainsaw 3 added land
12 * Fix lradar not to let land units loaded on land units use radar.
13 Broken since 4.0.0 added trains.
14 * Fix strength to ignore land units loaded on land units. Broken in
16 * Fix navigate and march to find paths longer than a few sectors
17 again (7 for 64 bit hosts, 3 for 32 bit hosts). Broken in 4.3.27.
18 * march sub-command 'i' now shows number of military and land units
20 * New server option -F to force start even when state looks bad.
21 Risks crashes and further corruption, but gives deities a chance to
22 fix up a bad game state with edit commands and such.
23 * empdump -x no longer refuses to export game state that looks bad.
24 Gives deities another tool to fix up a bad game state.
25 * Land units loaded on land units fight che again, as they used to
27 * When a land unit dies fighting che, land units loaded on it get
28 unloaded, and planes loaded on it die. Before, the update left
29 them stuck on their dead carrier. Impact like the next item.
30 Abusable. Broken since Chainsaw 3 added land units.
31 * The update no longer destroys ships, planes and land units for lack
32 of maintenance. Before, it left any embarked planes, land units
33 and nukes on their dead carrier. In this state, units behaved as
34 if their carrier was still alive, with additional protection from
35 the fact that a dead carrier can't be damaged or boarded. If
36 another unit with the same number got built, it picked up the stuck
37 cargo. The cargo got teleported to its new carrier when the
38 carrier moved. Abusable, but it involves going broke, so it's
39 rarely practical. Slightly more practical before 4.3.6 removed
40 budget priorities. Broken for ships and land units when Empire 2
41 added their maintenance cost, and for planes when v4.3.3 replaced
42 nuclear stockpiles by nuke units.
43 * Fix bogus internal error triggered by navigate and march
44 sub-commands 'r', 'l' and 's'. Broken in 4.3.27.
45 * Fix client not to reject redirections and execute containing
46 non-ASCII characters with a bogus scary warning when using UTF-8.
47 * Fix execute not to mangle non-ASCII characters in the argument when
48 prompting for it while login option utf-8 is on.
49 * Fix handling of non-ASCII and control characters in batch files.
50 * Conversion from UTF-8 to ASCII ate the character following a
51 replaced non-ASCII character. Buffer overrun possible if the
52 terminating zero gets eaten. Could happen in players, read, flash,
54 * Fix handling of empty commands:
55 - Time used was not updated.
56 - Mortal player wasn't logged off for game hours, game down, and
58 - Notifications were delayed: going broke, becoming solvent, new
59 telegrams (toggle inform off only), new announcements, capital
61 * Minor tweaks to nightly build.
62 * Server's and empdump's sanity checking of configuration and game
63 state is now more rigorous.
64 * Deity xdump no longer dumps unused countries' realms.
65 * Remove option LANDSPIES. Deities can customize the land table to
67 * Remove option TRADESHIPS. Deities can customize the ship table to
69 * Configuration table changes (builtin and custom):
70 - Rows must be in ascending uid order.
71 - Omitting rows in tables item, sect-chr and infrastructure is no
73 - Custom tables now replace the builtin table completely. Before,
74 omitted rows defaulted to the builtin version, except at the end
75 of a table. Commenting out unwanted stuff just works now.
76 - Permit custom table product having fewer than 14 entries.
77 - Reject custom tables where customization has no effect (updates,
78 table, meta, all symbol tables) or where it's unsafe (news-chr).
79 - Input is checked more rigorously.
81 - Don't touch plane file when import fails.
82 - Refuse import of incorrectly sized table instead of silently
83 creating one the server will reject.
84 - Replace old state completely. Before, omitted rows in the dump
85 defaulted to the old state, except at the end of a table.
86 - Input is checked more rigorously.
87 * Fix xdump updates not to dump bogus extra updates.
88 * Fix use-after-free when a plane got shot down or aborted by flak.
90 * Friendlier diagnostics in the build command.
91 * Fix build to set nuke's tech exactly like for ships, planes and
92 land units. It's not currently used for anything.
93 * Research required for nukes was slightly off sometimes due to
95 * Bridge building required 0.005 tech less than advertised, fix.
96 * "show nuke" now obeys toggle techlists.
97 * Fix "show land s" to show columns xpl and lnd again. Broken in
99 * Code refactoring and cleanup.
100 * Documentation on custom tables, xdump updated.
103 Changes to Empire 4.3.27 - Sun Apr 17 11:36:29 UTC 2011
104 * License upgrade to GPL version 3 or later.
105 * Fix buy not to wipe out concurrent updates. Can be abused to
106 duplicate commodities.
107 * Don't let fighters, SAMs and ABMs intercept while on trading block.
108 * Don't let missiles interdict ships or land units while on trading
110 * Fix client to log long input lines untruncated.
111 * Fix client crash for long input lines.
112 * info subject pages now mark unusually long pages with a !.
113 * The edit command keys deprecated in 4.3.15, 4.3.17 and 4.3.20 are
115 * Fix give, setsector and setres not to wipe out concurrent updates.
116 * Fix explore, move, test, transport not to ignore spaces in path
117 arguments. Broken in 4.3.7.
118 * Improvements to map drawing commands:
119 - Don't fail silently when asked to draw a map around an invalid
120 unit, explain the problem.
121 - Deprecate bmap flag "r". Use (a prefix of) "revert" instead.
122 - bmap flags following "t" are no longer ignored. However, info
123 pages previously documented an argument "true" in addition to
124 flag "t". To keep that working, keep ignoring flags following
125 "t" when they're bad. But deprecate that usage.
126 - Reverting the bmap no longer draws a map.
127 - Bad conditionals could make the commands misinterpret their first
129 - The commands now fail when they reject their second argument.
130 * The xdump syntax deprecated in 4.3.12 is now gone.
131 * Fix satellite to fail on bad conditionals instead of ignoring them.
132 * Journal improvements:
133 - Optional logging of output.
134 - Long lines are no longer truncated.
135 - Login phase input is now logged, too.
136 - Commands are now logged. Allows making sense of input without
138 * Option BRIDGETOWERS is now disabled by default.
139 * Bridge towers now take 300 hcms to build, down from 400.
140 * Fix stop orders to expire even when the country is broke. Broken
142 * Fix march and navigate not to advise on "legal directions" when
145 - Much faster, especially for distribution, i.e. where it matters
146 most. Speedups in excess of 30x have been observed for updates
147 taken from real games.
148 - Old land path finder leaked memory occasionally.
149 - Old land path finder overran buffers for very long paths. A
150 malicious player can arrange sufficiently long paths, but it
151 takes a lot of land. Distribution, the distribute command, land
152 unit reaction, and automatic supply now handle arbitrary long
153 paths. Commands explore, move, test, transport, march, navigate
154 and path now handle paths up to 1023 characters. Command
155 bestpath shows paths longer than 1023 characters with the tail
157 - Old sea and air path finder treated destinations as unreachable
158 when the best path was longer than 99 characters. Command sorder
159 now handles arbitrary long paths. Commands bomb, drop, fly,
160 paradrop, recon, sweep and sail now handle paths up to 1023
161 characters. Autonav considers up to 1023 characters at the
162 update. Planes can fly missions up to 1023 sectors from their
164 * Automatic supply charged mobility for the path back to the source
165 instead forward to the sink.
166 * Make bestpath work for deities in foreign land.
167 * More robust savecore example script.
168 * Fix buffer overruns in the lookout, spy, map and nmap commands when
169 WORLD_X * WORLD_Y is not a multiple of 16.
170 * The path command's maps weren't always fitted to the path
171 correctly. Broken in 4.3.17.
172 * Land units no longer hit allied mines.
173 * Change sharebmap with yourself to do nothing instead of telling you
174 you're not friendly to yourself.
175 * You can now flash yourself. Enjoy!
176 * A race condition could make the flash command claim an ally was not
177 logged on when he was. Hard to trigger outside the lab.
178 * The flash command no longer prints "Flash sent" for deities. It's
179 annoying. It never did that for mortals.
180 * Plug memory leaks in mission code on a number of conditions:
181 - Submarines moving where own planes would interdict hostile
183 - Ground combat where countries hostile to one of the parties would
184 support if relations were right (allied to one party, at war with
186 - Ships or land units moving within hostile missile mission op
188 - Any player action within marine missile mission op areas that
189 could trigger the missile owners' missions.
191 - When you ordered a sector to attack with military, but lost the
192 sector before the attack was executed, and the new owner was
193 allied to you, the server got confused: it let the military
194 attack even though they were already dead, but not occupy.
195 - When you ordered a land unit to attack from an allied sector, and
196 the sector got lost before the attack was executed, the server
197 reported things as if you had owned the sector yourself. The
198 land unit still attacked when the new owner was also allied to
200 - When a land unit attacked out of an allied sector, its mobility
201 cost was computed as if the ally owned the land unit. Attacking
202 sectors old-owned by that ally was too cheap, and taking back
203 one's own was too expensive.
204 * Fix trade ships to pay off in own harbor. Broken in 4.3.17.
205 * Remove option SLOW_WAR. It hasn't been enabled in a public game
206 for years, and the code implementing it was buggy.
207 * Fix a bug in sail that limited the sail path to 27 instead of the
208 intended 28 characters.
209 * Fix race condition in transmission of flash and telegram
210 information messages that could double output and possibly crash
212 * Planes get to sweep and sonar only after flak and interception.
213 * Don't limit the radar command's range to fit its output into a
214 world map without clipping. The limiting goes back to Chainsaw 2.
215 * Make flak vs. pinpoint bombing consistent with ordinary flak:
216 - 4.3.6 reduced the plane abort chance on damage, but missed the
217 additional flak vs. pinpoint bombing. Fix that.
218 - Fix to charge mobility appropriate for damage.
219 * Prettier flak damage reporting.
220 * Fix bugs that could cause bmap updates from recon and satellite to
222 * Fix lookout to properly report sector ownership to deities.
223 * Suppress bogus messages deities with non-zero country number got
224 when attempting to navigate foreign ships or march foreign land
225 units. Such deity use hasn't worked since Empire 2.
226 * Deities can no longer fly foreign planes. It didn't fully work
227 since Chainsaw 3, and can trigger internal errors since 4.3.11.
228 * Don't split lines over several bulletins. The read command
229 normally merges these bulletins, but if they are more than five
230 seconds apart (clock jumped somehow), we get a bulletin header in
231 the middle of a line. Broken since Empire 2.
232 * Don't beep when plane, land unit or nuke die on a collapsing
233 bridge. Not nice, because it could beep many times, and could put
234 beeps in bulletins. Beeping was added in 4.0.18.
235 * Minor improvements to nuclear damage reporting.
236 * When a deity dropped a foreign nuke, parts of the output went to
237 the owner of the nuke instead of the deity.
238 * When a player triggered a foreign missile launch (mission or
239 interception), and the missile exploded on launch, part of the
240 report went to the player instead of the missile owner. This
241 disclosed the missile owner's origin. Broken in Empire 2.
242 * When autonav reported to a ship owner that it can't load or unload
243 foreign civilians, it used the sector owner's coordinate system.
244 This disclosed the sector owner's origin. Abusable.
245 * When nuclear damage bounced off a sanctuary, the bulletin to the
246 sanctuary owner used the attacker's coordinate system. This
247 disclosed the attacker's origin.
248 * When a deity used sweep, lmine, sail or sabotage with a foreign
249 plane, land unit or ship, its location was reported in the foreign
251 * When a deity asked for a foreign nation report, the capital
252 location was reported in the foreign coordinate system.
253 * Code refactoring and cleanup.
254 * Info file improvements.
256 Changes to Empire 4.3.26 - Mon May 24 16:37:40 UTC 2010
257 * Land units loaded on ships or land units can no longer fight che.
258 * When foreign land units were present, a che revolt could damage
259 them instead of the defending land units. This could let defenders
260 survive the revolt. They were captured or blown up if che took
262 * Fix che revolt to damage only land units that actually fight
263 * Fix loading x-light missiles on ships without capability plane.
264 These ships could only use their x-light slots for x-light planes,
265 not their plane slots. Broken in 4.3.17.
266 * Update bmap when nuclear detonation makes wasteland.
267 * Fix fly and drop to report discarded cargo items correctly.
268 * New client option -s to specify server host and port.
269 * Hitting landmines could crash the server. When not, the damage
270 reduction for capability engineer was applied unpredictably.
272 * Fix retreat and lretreat condition 'c'. Broken in 4.3.16.
273 * coastwatch and skywatch could see too far. Up to one sector for
274 practical radar ranges.
275 * skywatch now reports satellite uids. The uid is required for
276 launching a-sats since 4.3.23.
277 * Fix client not to send an empty line of input before aborting the
278 command on player interrupt (normally ^C).
279 * Fix sabotage not to kill the spy every time. Broken in 4.3.17.
281 * Info page fixes, manual page improvements.
283 Changes to Empire 4.3.25 - Sun Mar 21 08:27:37 UTC 2010
284 * Hitting seamines could crash the server. When not, the damage
285 reduction for capability sweep was applied unpredictably. Broken
287 * When an interdiction did damage other than collateral damage, the
288 planes that intercepted it from interdicted carriers used no
289 petrol. 4.3.24 fixed only the "no damage" case.
290 * Ship anti-missile defense failed to charge shells when the ship was
291 interdicted. The fix in 4.3.24 covered only launch.
292 * Fix a bug in navigate and march that let players lay mines free of
293 charge. Also fix them not to prompt for the number of mines.
294 * Missile exploding on launch could not damage its base if it was
295 armed with a nuke. Broken in 4.3.23.
296 * When a torpedo attack triggered a return torpedo, the news reported
297 it to be fired by the attacker instead of the defender.
298 * Interdiction attacked submarines with surface-only weapons. Broken
300 * Fix a bug in lradar, path, radar, route, satellite, sect and survey
301 that could leak maps to other players. Broken in 4.2.0. Fixed in
302 4.2.8 for bmap, lbmap, lmap, map, nmap, pbmap, pmap, sbmap and smap
304 * files could clobber the game when reading confirmation fails.
305 * fairland no longer rejects small worlds without trying.
307 Changes to Empire 4.3.24 - Tue Jan 26 21:29:14 UTC 2010
308 * The client sometimes hung under Windows when the server closed the
309 connection. Broken in 4.3.23.
310 * Fix navigate and march not to crash the server when a path argument
311 consists of a valid path plus whitespace. Broken in 4.3.7.
312 * When a client sent a blank line in the login phase, the server
313 crashed on some systems.
314 * Fix crash bug in bomb, drop, fly, paradrop, recon and sail. Broken
316 * Fix bogus internal error on escort, recon, and satellite launch.
317 Mostly harmless, as error recovery worked fine. Broken in 4.3.23.
318 * Stop ship and land unit movement on interdiction even when it does
320 * When an interdiction did no or only collateral damage, the planes
321 that intercepted it from interdicted carriers used no petrol, and
322 interdicted land units were immune to collateral damage.
323 * The limit for the number of sectors, ships, planes, land units,
324 nukes, and so forth is now large enough not to matter. It used to
325 be 32768 on common machines. The sector limit was introduced in
326 4.3.12. World x- and y-size are still limited to 65536 on common
328 * News use much less space, and thus I/O. Space was wasted in
329 4.3.12. Side effects of the change:
330 - Expiry of old news no longer updates news timestamps. Updating
331 timestamps was wrong, because it defeated incremental xdump news.
332 - The empdump utility can no longer update timestamps of imported
333 news. Unfortunate, as it breaks incremental xdump news.
334 * New news selector duration, the time span covered by this news item
336 * ABMs failed to charge supplies when their sector was the
337 intercepted missile's target. The stock game's ABMs use no
339 * Ship anti-missile defense failed to charge shells when the ship was
340 the missile's target.
341 * Code refactoring and cleanup.
343 Changes to Empire 4.3.23 - Sun Dec 13 16:34:49 UTC 2009
344 * Fix missile interception not to intercept tactical and marine
345 missiles attacking missiles or satellites. No such missiles exist
346 in the stock game. Interception of tactical ABMs could crash the
347 server. Broken in Empire 2.
348 * Missiles missing their target do collateral damage again. Was
349 disabled because of bugs in 4.0.18 for manual launch and in 4.3.16
350 for automatic launch.
351 * News reported victim as actor for sub-launched anti-sat and ABM.
352 * Defense value of missiles vs. ABMs and satellites vs. anti-sats
353 failed to improve with tech.
354 * Fix a bug that let missiles interdict ships outside their op area.
355 This could happen when a group navigating together was partly
357 * Only bomb strategic and launch at sector can use nukes. Before,
358 they could also be used by missions, bomb pinpoint, and launch at
359 ships, but there were several bugs and inconsistencies, and the
360 code was messy. The arm command now rejects marine missiles in
361 addition to satellites, ABMs and SAMs, and clears the mission. The
362 mission command now rejects planes armed with nukes.
363 * Missiles exploding on launch pad no longer set off their nukes.
364 * The launch command now more accurately reports why a missile can't
365 be equipped. It no longer draws supplies automatically.
366 * Manually launched anti-sat now always kills when it hits, for
367 consistency with automatically launched ones.
368 * Don't permit nukes on satellites, ABMs and SAMs. Nukes on
369 satellites could be armed and disarmed even in orbit. Nukes on
370 ABMs and SAMs were lost without effect when their missile
371 intercepted. The stock game is not affected, because its
372 satellites, ABMs and SAMs all have zero load.
373 * Remove obsolete plane capabilities stealth and half-stealth. Not
374 used by the stock game.
375 * Penalize fighter combat value for any load, not just bombs. The
376 stock game's fighters can't carry anything but bombs.
377 * Make bomb work for non-tactical cargo bomber. No such planes exist
379 * Revised cargo plane rules: a cargo flight can be either an airlift
380 or an airdrop now. Airlifts carry more cargo than airdrops. A
381 cargo drop or paradrop with a non-VTOL plane is an airdrop.
382 Anything else is an airlift. This makes paradrop loads consistent
383 with drop loads. Paradrop with VTOL transports now carries twice
384 the punch, and drop with non-VTOL transports hauls less than fly.
385 In particular, the stock game's tr can't drop guns anymore.
386 * Enforce plane selection rules more tightly:
387 - bomb command can select only planes with capability bomber or
388 tactical. Before, other planes with non-zero load flew along,
389 but their bombs were silently lost.
390 - sweep command can select only planes with capability sweep.
391 Before, other planes performed ordinary reconnaissance instead.
392 - drop command can select only planes with capability cargo.
393 Before, other planes flew along but dropped nothing.
394 * Fix paradrop to fail without destroying the paratroopers when the
395 player owns the target sector.
396 * Launching an anti-sat now takes the target plane as argument.
397 Before, it took a sector argument, and targeted the lowest-numbered
398 satellite there. Rather inconvenient when your own satellite masks
400 * Remove option PINPOINTMISSILE. Deities can customize the plane
401 table to disable marine missiles.
402 * Ridiculously impotent nukes could do unpredictable interdiction
403 damage. No such nukes exist in the stock game.
404 * The production command could mispredict resource-depleting level
405 production. No such products exist in the stock game. In fact,
406 they'd be highly unusual.
407 * The update could crash or corrupt the game when a (misconfigured)
408 product depleted resource "none".
409 * Revamp the Windows port based on ideas stolen from Gnulib. Share
410 the code between server and client.
411 * Don't log out player when update aborts a command under Windows.
412 Broken in 4.3.20, and not fully fixed in 4.3.21.
413 * Fix accepting connections from hosts with "long" IPv6 address. The
414 internal buffer had insufficient space.
415 * Delay shutdown up to 3s to let player output buffers drain.
416 * Fix a race between main thread and player threads, which could
417 theoretically make the server crash on start.
418 * Clean up synchronization between commands, update and shutdown, and
419 when player threads sleep on I/O.
420 * Clean up the cruft that has accumulated in and behind the empio
421 interface, and, to a lesser degree, the empthread interface.
422 * Fix time difference underflows in pthread and Windows code. They
423 could potentially cause hangs, although none have been observed.
424 * Make budget's "Sector building" line look better.
425 * Make sector maintenance cost configurable. New sect-chr selector
426 maint. Capitals now pay maintenance regardless of efficiency.
427 * Overhaul show sect b.
428 * Fix mine production resource limit for sector peffic != 100. This
429 affects mountains in the stock game, but only with an impractically
430 large number of ETUs per update.
431 * Code refactoring and cleanup.
432 * Info file fixes and improvements.
434 Changes to Empire 4.3.22 - Sat Apr 25 11:56:29 UTC 2009
435 * Fix a Windows client bug that could lead to hangs, at least with
436 some versions of the C run-time. Broken in 4.3.11.
437 * Allow building without curses terminfo. Highlighting in the client
439 * Really fix bomb not to wipe out plane updates made while it asked
440 for pinpoint targets. The fix in 4.3.21 didn't cover escorts.
441 * Fix tend land not to wipe out concurrent updates.
442 * Automatic supply fixes:
443 - Ships with just two shells could fire a torpedo to return fire or
445 - Ships with just one shell could use their anti-missile defense.
446 - Land units were considered in supply even when they had not quite
447 enough supplies. Such land units could defend without penalty,
450 * Fix update to take dead units off carriers.
451 * Standalone client distribution built empire instead of empire.exe
452 for Windows. Broken in 4.3.0.
453 * Fix client to abort script execution on SIGINT.
454 * Fix Windows client not to hang on EOF on standard input when that
456 * Fix a client bug that could make it hang when EOF on standard input
457 follows an execute command closely.
458 * Seamines under bridge spans were disabled a long time ago, in
459 Empire 2. The drop command refuses to mine there. Change mine
460 command to do so as well.
461 * Seamines under bridge spans were mistaken for landmines by ground
462 combat, land units retreating from bombs, and non-land unit ground
464 * When a bridge tower collapsed, its landmines magically became
466 * Don't log out player when he interrupts a command. Broken in
468 * Code cleanup and portability improvements.
469 * Info file and documentation fixes.
471 Changes to Empire 4.3.21 - Mon Mar 9 21:34:52 UTC 2009
472 * Fix swapsector not to wipe out concurrent changes to the swapped
474 * Fix a bug in crash dumping that could mess up the journal and, at
475 least in theory, mess up commands info, read, turn, and wire;
476 announcement expiry, and reading of econfig and schedule.
477 * Fix bomb not to wipe out plane updates made while it asked for
479 * When bombing ships with a force containing both planes with and
480 without capability ASW, the bomb command could fail to report
481 presence of submarines, and could refuse to bomb ships when there
482 were only submarines.
483 * Leaving land units behind after a victorious attack could in some
484 cases wipe out changes made to them since the victory.
485 * The timestamp selectors added to commodity, load and trade in
486 4.3.12 could lead to spurious command failures. None have been
487 observed in the wild.
488 * Don't log out player when update aborts a command. Broken in
490 * Code refactoring and cleanup.
492 Changes to Empire 4.3.20 - Fri Feb 20 18:14:20 UTC 2009
493 * Option LOANS is now disabled by default.
494 * Option RAILWAYS is now enabled by default.
495 * Many fixes to automatic supply:
496 - Planes flying interception or support missions, abms intercepting
497 ballistic missiles, and the launch command for missiles and
498 anti-sats could all supply more shells than necessary, lose
499 shells, or conjure them up.
500 - Ships shooting down marine missiles could supply more shells than
501 necessary, or lose shells.
502 - Supply ships could conjure up shells when firing guns using
503 multiple shells, or launching torpedoes, or dropping depth
504 charges, or shooting down marine missiles. No supply ships
505 capable of doing that exist in the stock game.
506 - Supply engineers could conjure up shells when laying mines. They
507 don't exist in the stock game.
508 - load, lload and supply could supply land units with enough food
509 from the sector containing them to starve the sector.
510 - Sectors were charged too much mobility for moving supplies
512 - Land units serving as supply source no longer draw supplies
513 recursively, because the bugs there are too hard to fix to be
515 - Defending and reacting units only checked whether they could draw
516 supplies, but didn't actually draw them.
517 - load, lload, supply, assault and board no longer supply land
518 units from ships carrying them. This feature, added in 4.0.14,
519 was inconsistent with other ways to supply.
520 - Don't use automatic supply to avoid starvation at the update. It
521 adds complexity to the update. How much good it does to players
522 is highly doubtful; certainly nobody can rely on it. It isn't
523 covered by the starvation command. Ships or land units could
524 steal enough food from their sector to make it starve.
525 - lmine could only fetch shells for engineers that use ammo. The
526 stock game's engineers all do.
527 The changes listed for load and lload are actually lies, because
528 supply has been disabled there since 4.3.17.
529 * Don't let an engineer lay mines while it is on a ship or land unit,
530 or in a foreign sector.
531 * Sectors and ships no longer need shells to fire flak.
532 * Use IPv4 and v6 only when suitable interfaces are configured.
533 * Fix turn off not to fail when the message is empty. Broken in
535 * Don't nag the deity about game hours restriction in force all the
537 * Tell deity when the game is down, just like players. Also make the
538 information available in xdump, as game selector down.
539 * Corrupt mailboxes could crash the server.
540 * Fix reject accept. Broken in 4.3.4.
541 * If a player was at a prompt when the deity turned the game down, he
542 was allowed to enter one more command.
543 * Air defense is no longer separate from interception. Putting a
544 plane on air defense now merely changes where it intercepts.
545 Separate air defense added too much pointless complexity. Its
546 implementation violated design assumptions of the intercept code.
547 Because of that, the same plane could intercept both an air defense
548 mission and the planes that triggered it, and the damage it
549 received in the first interception was wiped out.
550 * Intercept the same all along the flight path. In each sector, any
551 country owning the sector, a surface ship or a land unit there gets
552 to intercept. Before, only the sector owner got to intercept,
553 except for the assembly point and the target sector. In the target
554 sector, any country owning surface ships or land units got to
555 intercept in addition to the sector owner. Thus, a sector owner
556 with surface ships or land units there got to intercept twice. The
557 sector owner did not get to intercept at the assembly point,
558 even when it was the target sector.
559 * Spotting rule changes:
560 - Ships and land units now spot overflying planes along all of the
561 flight path instead of just the target sector, and no longer
562 report allied planes.
563 - Planes now spot ships and land units only when flying recon or
564 sweep, and along all of their flight path instead of just the
565 target sector. It still takes a spy plane to identify ships and
567 - Planes now spot ships and land units in a sector even when all
569 - Planes now spot all foreign ships and land units, not just
571 * Fix SAM interception for intercepts other than the first.
572 * Fix air defense and flak over sectors allied to the planes. Air
573 defense was broken in Empire 2. Flak was broken in 4.2.8.
574 * Establishing contact by spotting planes from sectors didn't work.
575 * Fix reconnaissance patrols to use sonar when any capable plane is
576 present. Before, all planes had to be capable.
577 * Fix recon and sweep not to spy after all spy planes are gone.
578 * Fix a bug that made multiple clients running on the same Windows
579 machine interfere with each other. Broken in 4.3.11.
580 * Fix enforcing game hours for players already logged in. Broken in
582 * Fix distribution not to abandon a distribution center by exporting
584 * Many fixes to load, unload, lload and lunload:
585 - Now usable for deities.
586 - Plug loopholes that let you steal foreign commodities by making
587 load/lload unload and unload/lunload load through use of negative
589 - Fix not to let you give away civilians.
590 - You can't use lload in foreign sectors or lunload with foreign
591 land units anymore. Loading stuff in foreign sectors was
592 prohibited already for ships.
593 - lload and lunload now work on foreign land units only when
594 they're explicitly named by uid. This matches behavior of load
596 - Fix to test relations of foreign object's owner to player instead
597 of the other way round.
598 * Make sure land units with maximum mobility can attack mountains.
599 * Fix land unit attack mobility cost. Broken in 4.3.6.
600 * Conditions comparing string-valued selectors like wing to unquoted
601 values are now interpreted more smartly. Before, unquoted strings
602 were prone to be interpreted as selector names even when that made
603 no sense. You still have to disambiguate truly ambiguous cases
604 like w=w for planes, e.g. as wing=w or w='w'.
605 * Fix reporting of shot spies in news. Broken in 4.3.16.
606 * Remove econfig key mission_mob_cost. Questionable feature, and
607 hasn't been used in a long time.
608 * Reserve and escort missions now have an op-area, like all the other
610 * Land units now react only when on a reserve mission. The lrange
611 command is gone. The edit command still accepts and ignores the
612 land unit key 'P' for compatibility, but it is deprecated.
613 * Fix a bug that could mess up mission op-area when the range of
614 ship, plane or land unit on the mission decreases, e.g. through the
616 * Reserve missions no longer give a bonus to reaction range.
618 * Code refactoring and cleanup.
620 Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
621 * LWP doesn't work with Darwin due to OS bugs, avoid it for now.
622 * Don't let ships double-retreat first on 'i' (injured) and then on
623 'h' (helpless) when shelled.
624 * Fix a bug that suppressed the "sunk!" message. Broken in 4.3.17.
625 * Log out player when maximum time per day is exceeded. Before, he
626 could remain logged in with visitor privileges only, but once
627 logged out could not log back in.
628 * If a player was at a prompt when either game hours restriction
629 started or maximum time per day was exceeded, he was allowed to
630 enter one more command.
631 * Deitying a capital failed to charge money and report news. Broken
633 * Overhaul accounting of play time, fixing minor inaccuracies.
634 * Fix parsing of 24:00 in econfig key game_hours and
636 * New option RAILWAYS.
637 * Che ages just like military reserves (1% per 24 ETUs).
638 * Permit ships to assault the sector they're in.
639 * Sectors eating less than one unit of food don't make one unit of
640 food for free anymore. They still can't starve.
641 * New concept sector terrain. Deities can use it to make sectors
642 other than wilderness redesignatable. See sect.config for more
644 * Represent play time in seconds rather than minutes. This affects
645 xdump: nat selector minused (counting minutes) is replaced by
646 timeused (counting seconds).
647 * Improved nightly build, with additional tests.
649 Changes to Empire 4.3.18 - Sat Oct 18 18:39:17 UTC 2008
650 * Fix building of planes, land units and nukes with uids that have
651 never been used before. This could crash the server on some
652 systems in certain states. Broken in 4.3.17.
653 * Improved nightly build, with restructured and extended tests.
655 Changes to Empire 4.3.17 - Sat Sep 20 16:07:44 UTC 2008
656 * Fix standalone client build for Windows. Broken in 4.3.11.
657 * Disable automatic supply of land units on load for now, it's
658 broken, and can be abused to duplicate supplies.
659 * Make trade show exactly what's on sale, remove option SHOWPLANE.
660 * Stop ships, planes, land units and nukes on violent takeover, just
662 * Wipe orders when ships, planes, land units and nukes are taken over
663 violently or given away peacefully. Fleet, wing, army and mission
664 were already cleared in many, but not all cases. Other orders were
665 never cleared: mission op-areas (visible in xdump), ship autonav
666 orders, ship sail path (including ship to follow and mobility
667 quota), land unit retreat orders, plane range limit, and land unit
669 * Fix takeover of stuff by attack, assault, board, lboard, paradrop
671 - Corrupt land unit file could lead to infinite recursion.
672 - Take over nuke armed on plane along with the plane. Broken in
674 - Taking over land units with negative mobility increased mobility
675 to zero. Ditto for planes embarked on ships or land units.
676 * Fix a bug that made set and xdump not recognize unused trade lots
678 * Fix giving away stuff by trading it:
679 - When an armed nuke is sold separately from its plane, take it off
680 the plane. You couldn't do that before 4.3.3.
681 - Give away nuke armed on sold plane along with the plane. Broken
683 - Don't zero mobility of planes and land units on sold ships.
684 * Fix giving away stuff by unloading from its carrier: Give away any
685 nukes armed on planes (broken in 4.3.3) and land units loaded on
686 land units. The latter can't happen in the stock game.
687 * Fix giving away stuff by scrapping or scuttling its carrier:
689 - Disarm the nuke from a plane instead of destroying it.
690 - Give away any loaded land units and planes, too.
692 - Fix scuttle to ask for confirmation when scuttling a tradeship in
693 an unsuitable sector even when the tradeship is pirated. Broken
695 - Fix scuttle to require 2% harbor efficiency for a trade ship to
696 pay. Also require at least friendly relations.
697 - Make autonav refuse scuttle orders in unsuitable sectors.
698 * Clean up rules on where you can scrap stuff:
699 - Ships in own or friendly, efficient harbors (relations used not
700 to matter, contrary to info)
701 - Planes in own or allied, efficient airfields (friendly used to
702 work as well, contrary to info)
703 - Land units in any own or allied sector (relations used not to
704 matter, and you couldn't scrap them on ships)
705 Also tell player why something can't be scrapped instead of
706 ignoring it silently.
707 * Rewrite the broken code to move land units, planes and nukes along
708 with their carrier. The old code was a hack that didn't update
709 timestamps (so incremental dumps didn't pick up the movement), and
710 it didn't cover all uses. The update, in particular, was prone to
711 see cargo in old locations, which could screw up repairs.
712 * Expire lost items at the update instead of continuously.
713 * Replace econfig key lost_items_timeout by lost_keep_hours.
714 * Minor Windows threading fixes.
715 * Journal now uses human-readable names to identify threads.
716 * Ship and land unit load counters are no longer stored in game
717 state, because they duplicate information already there. Same for
718 the type of nuke loaded on a plane. Remove field nuketype from
719 xdump plane. Clients can simply find the plane's nuke instead.
720 The edit command still accepts and ignores the plane key 'n' for
721 compatibility, but it is deprecated.
722 * Ship and land unit load counts as displayed by ship, sdump, land,
723 ldump, ship selectors nplane, nxlight, nchoppers, nland, and land
724 selectors nxlight, nland are now reliable. They used to get out of
726 * Ship load counts now reflect what is loaded, not how it is stored.
727 For instance, if a light carrier, capable of carrying 4 x-lights
728 and 20 light planes carries nothing but 5 sams, we now have
729 nxlight=5, nplane=0 instead of nxlight=4, nplane=1.
730 * New cargo lists data structure to let code find loaded planes, land
731 units and nukes easily and efficiently.
732 * Revamped upkeep of lost file. It should be reliable now.
733 * Disable the ill-advised error recovery on sector access that swept
734 bugs under the carpet rather than recovering from them.
735 * Occupied sectors no longer revert to the old owner when all
736 military and land units go away. This feature was added in
737 Chainsaw 3. It wasn't integrated properly with the che code
738 (things went wrong when che killed all defenders, but couldn't
739 convert the sector due to its loyalty), and combat code (if an
740 attack killed off all local defenders and got defeated by reacting
741 units, the sector changed ownership anyway, silently).
742 * Include destination coordinates in interception and plane mission
744 * Client could misdiagnose redirections and executes as unauthorized,
745 or die outright. Broken in 4.3.11.
746 * Fix xdump realm to dump player instead of absolute coordinates.
747 Disclosed the true origin. Broken in 4.3.0.
748 * Fix spy to reliably avoid spying same sector more than once.
749 * The map drawing code could smash the heap when the world was
751 * When a satellite's launch trajectory was off, its coordinates could
752 get screwed up, which made it invisible in skywatch.
753 * Fix several bugs that made the path command screw up when the path
755 * Fix the default size of the map shown by move, test and transport
757 * Fix bugs that could make arguments in area or dist syntax miss
758 ships, planes, land units and nukes at the border of the selected
759 area, if that area spans the whole world. In sufficiently small
760 worlds, it could also make radar miss satellites and ships, sonar
761 miss ships, satellite miss ships and land units, nuclear
762 detonations miss ships, planes, land units and nukes, automatic
763 supply miss ship and land unit supply sources, ships and land units
764 fail to return fire, ships fail to fire support.
765 * Maps sometimes showed x-coordinates as three lines instead of two
767 * Improved nightly build, tests in particular.
768 * Code refactoring and cleanup.
770 Changes to Empire 4.3.16 - Sat Aug 9 15:56:52 UTC 2008
771 * Production command incorrectly limited the number of graduates,
772 happy strollers, technological breakthroughs and medical
773 discoveries produced by a sector to 999. Broken in 4.2.15.
774 * Fix a bug in improve that could let you spend more money than you
776 * Fix work command not to spend more mobility than requested, and to
777 round mobility use randomly instead of down.
778 * Commands demobilize, convert and work no longer let you spend more
779 money than you have. Commands demobilize and convert no longer ask
780 for confirmation before spending more than half your money. Saving
781 that feature would have been more work than it's worth.
782 * Remove undocumented key 'd' at bomb ship, plane and land unit
784 * Fix land unit flak when pin-bombed to match flak when overflown:
785 proportional to efficiency, and randomly rounded. Was missed in
787 * Don't permit bombing of embarked planes and land units.
788 * Fix capital maintenance to charge at 60% efficiency.
789 * launch command now requires only 40% plane efficiency, for
790 consistency with other ways to launch missiles.
791 * Disable collateral damage when automatically launched missiles miss
792 their target. Collateral damage was done even when the launch
793 failed or the missile got intercepted. It's been disabled for
794 manually launched missiles since 4.0.18, for the same reason.
795 * Fix a bug that corrupted the lostitems file. Broken in 4.3.12.
796 * Show command changes:
797 - Move product information from "show sect c" into new "show
798 product", and reformat it to be easier to understand.
799 - New column navigability in "show sect s".
800 - "show sect s" now shows the packing bonus type instead of
801 selected packing bonuses. "show item" shows the actual bonuses
803 - "show sect b" now shows the usual values in addition to unusual
805 * Fix interdiction to obey op-area for missiles.
806 * Fix a bug that caused a stale sources.mk to be distributed in the
807 4.3.14 an 4.3.15 tarballs. The latter does not build out of the
809 * Don't strip tab characters from quoted command arguments. Broken
811 * shutdown commands now always take effect immediately. Before, they
812 could be delayed by up to a minute.
813 * shutdown could start multiple shutdown threads when you initiated a
814 shutdown shortly after cancelling one. This screwed up the timing
816 * Deity syntax of zdone changed, and is now documented in info.
817 * The threshold command could be tricked into accepting negative
819 * Fix designate to always write updated bmap to disk.
820 * Fix bomb to fail on empty <pin|strat> argument instead of flying
822 * Fix a bug in distribute that screwed up the current sector's
823 distribution center when the command got aborted.
824 * Commands arm, bomb, deliver, drop, fire, fly, paradrop, recon,
825 lmine, order, power, range, sail, shutdown, sweep and tend did not
826 honor command abortion at some prompts.
827 * Fix a bug in handling of EOF from client that could bite in the
829 - EOF at target prompts for bombing commodities, ships, planes and
830 land units sent the server into an infinite loop that ate all
832 - EOF at sail's path prompt crashed the server.
833 - EOF at some prompts in deliver, designate, fly, morale, zdone,
834 attack and assault didn't abort the command.
836 * Selector terr is now the same as terr0 for mortal players, and
837 dterr for deities. This matches how the territory command works.
838 Unfortunately, this required us to rename xdump sect field terr to
839 terr0. Sorry about that.
840 * Fix bomb not to let you bomb dead ships and land units.
841 * Make the retreat command a bit more helpful on retreat conditions,
842 and make it fail on bad conditions.
843 * Fix the mapper scripts. Broken in 4.2.0.
844 * Fix flying commands not to let planes do double duty as escorts.
846 * When a minesweeper hit a mine after sweeping, the mine wasn't used
847 up. If it sank the minesweeper, the code accessed freed memory,
848 which could clobber the ship file or worse. Broken in 4.0.17.
849 * Don't let non-light units board ships that can't carry them.
850 * Capitals can now employ up to 1000 civilians instead of 999.
851 * Spy command changes:
852 - Spy now requires sector military. Before, presence of land units
853 was sufficient, but spies shot were only deduced from sector
854 military. If you lost more spies than you had sector military,
855 the rest came back from the dead.
856 - Spy no longer ignores non-sea sectors without civilians, military
858 - Remove columns lnd, pln from spy report. The values didn't match
859 the reported land units and planes, and could leak the presence
861 - Establish contact when spy succeeds even though the spy was
863 * Fix news reporting and damage when land units interdict ships in
864 sectors other than sea.
865 * Fix land unit return fire damage to ships to take accuracy into
866 account, like the fire command and interdiction does.
867 * Remove the inconsistent shelling damage reduction for range. Fire
868 command got damage reduced by 10-20% with a chance depending on
869 range ("Wind deflects shells"). Ships interdicting got it reduced
870 by half. Other ways to shell did not get damage reduced for range.
871 * Fix ground combat to report defending land units. Broken in 4.3.4.
872 * Info file and documentation fixes and improvements.
874 Changes to Empire 4.3.15 - Sun May 18 08:59:30 UTC 2008
875 * The edit command keys deprecated in 4.3.10 are now gone.
876 * fairland now obeys game file locks.
877 * Do not leak world creation time in files utility, because that
878 facilitates attacks against fairland's PRNG. Broken in 4.3.12.
879 * Fix starvation not to starve one more than it should. The last man
880 on a boat or land unit now can't starve anymore.
881 * Fix a crash bug in satellite. Broken in 4.2.7 and not fixed
883 * Fix a coordinate normalization bug that could theoretically lead to
884 buffer overruns and other unpleasantness. None have been
885 reproduced, though. Broken in 4.3.12.
886 * Remove option FUEL. The abstract idea of tying ships and land
887 units to a logistical tether is sound, the concrete implementation
888 as option FUEL is flawed. It adds too much busy-work to the game
889 to be enjoyable. It hasn't been enabled in a public game for
890 years. The code implementing it is ugly, repetitive, and a burden
891 to maintain. The edit command still accepts and ignores the fuel
892 keys for compatibility, but they are deprecated.
893 * Fix pin-bomb not to report subs when there are none.
894 * You now have to take a capital to capture the victim's money, loans
895 or market lots. Merely obliterating the capital doesn't cut it.
896 It still makes the victim lose money, though.
897 * Fix a bug that could theoretically allow sacking of non-existant
898 capitals of visitors, deities and such.
899 * You now gain BTUs and MOB_ACCESS mobility before the first update
900 again. You didn't since 4.3.10 introduced the ETU clock.
901 * Fix edit to detect when the edited object changes while it's being
903 * Fix xdump nat for relations: it got HIDDEN backwards. Broken in
905 * Fix origin command not to prompt twice for its argument. Broken in
907 * Info file improvements.
909 Changes to Empire 4.3.14 - Mon May 5 04:57:03 UTC 2008
910 * Another round of fixes to the fire command:
911 - Don't disclose where the target retreated to.
912 - Charge the target shells for returning fire.
913 - Always use guns when the target is out of range, even if it's a
914 submarine. Before, the difference in shell use disclosed whether
915 the target is a submarine. Loophole opened in 4.3.12.
916 - Make depth charges again work with just one shell. Failing the
917 command in that case lets players find out whether the target is
918 a submarine. Loophole opened in 4.3.12.
919 - Detect when the firing sector, ship or land unit changes across
920 the target prompt. Can be abused to duplicate commodities, and
922 * Fix parsing of anchor-relative time in update schedule. Broken in
924 * Fix logging of player input in the journal to include command
925 interruption and EOF.
926 * Fix oversights in 4.3.12's change to keep track of flying planes:
927 planes could be erroneously reported damaged by their own ground
928 strikes. Happened with missions and the launch command.
929 * Fix load not load hardened missiles.
930 * Fix harden not to harden missiles loaded on land units.
931 * New server option -E to choose what to do on recoverable internal
932 error. You can now make the server dump core and keep going (not
933 implemented for Windows). New econfig key post_crash_dump_hook to
934 run a program after crash-dumping. See scripts/savecore for an
936 * Journal entries are now flushed to disk right away even when the
937 server is not running in debug mode.
938 * Don't let land units load trains.
939 * Allow deity to display power report for all types of countries,
941 * Fix designate's check for disallowed sector types. Broken in
943 * Documentation fixes.
945 Changes to Empire 4.3.13 - Tue Apr 15 19:03:11 UTC 2008
946 * Work around strptime() lossage on some systems. Fixes the parsing
947 of the schedule file there.
948 * New selector maxnoc for xdump version.
949 * Fix initialization of realms in newcap. Broken in 4.3.12.
950 * Fix add for status arguments active, god, delete. Broken in
952 * Info file, manual page and documentation fixes.
954 Changes to Empire 4.3.12 - Wed Apr 2 05:35:06 UTC 2008
955 * Fix rounding error in update that could result in more babies than
956 food permits, and negative food.
957 * Fix a bug that could lead to unfair thread scheduling under
959 * Fix ship and land unit missile interdiction and ballistic missile
960 interception to require a proper base. Before, missiles could
961 launch from anywhere for that.
963 - Don't allow launching from unowned sectors.
964 - Don't destroy missiles stuck on foreign ships.
965 - Use up the supplies required for launching an asat only when it
967 - Don't ignore satellites' fuel use.
968 * Deity command newcap now requires its second argument (sanctuary
969 coordinates). Before, it tried to pick a suitable location when
970 none was given. The code implementing this feature had problems,
971 and it's not worth fixing, because it is obscure, and rarely (if
972 ever) used: no conscientious deity would use it for a real game,
973 and for blitzes fairland does a better job.
974 * Keep track of flying planes properly. This fixes a number of bugs:
975 - While the bomb command awaited pin-bombing target input from the
976 player, other players could interact with the pin-bombers and
977 escorts as if they were sitting in their bases: spy them, damage,
978 capture, load, unload, or upgrade them, even get intercepted by
979 them. But any changes to those planes were wiped out when they
981 - The bomb command could bomb its own escorts, directly (pin-bomb
982 planes) or through collateral damage, strategic sector damage,
983 collapsing bridges or nuke damage. The damage to the escorts was
984 wiped out when they landed.
985 - If you asked for a plane to fly both in the primary mission and
986 escort, you got charged fuel for two sorties instead of one.
987 * Plug memory leaks in plane interception.
988 * Fix trade not to let the buyer teleport satellites (not in orbit)
989 and asats to an arbitrary sector. Abusable, because abms
990 intercepted from anywhere, and satellites could be launched from
992 * The PRNG seed is now logged in the journal.
993 * Fix nightly build for Windows.
994 * Fix crash bug that bit when custom tables contained columns names
995 that existed, but weren't supposed to be in the custom table.
996 * New timestamp selector for commodity, country, game, loan, nation,
997 news, realm, trade, treaty to support incremental xdump.
998 * Deity commands newcap and add wipe the nation more thoroughly. add
999 no longer touches relations and flags for status active and god.
1000 * New utility program empdump to export and import game state as
1001 plain text. Check its manual for details, including limitations.
1002 * Plane, ship and land unit stats are no longer stored as game state,
1003 but recomputed from tech and base stats as needed.
1004 * xdump ver is no longer a special case. Syntax "xdump ver" is now
1005 deprecated. Use "xdump version *".
1006 * Fire and torpedo cleanup and bug hunt:
1007 - Plug memory leak in fire command.
1008 - Fix ammunition use when returning fire: resupply could lose
1009 shells when returning fire to multiple targets, and land units
1010 were charged per target instead of just once.
1011 - Interdicting land units now resupply shells automatically, for
1012 consistency with other ways to fire.
1013 - torpedo and fire no longer resupply shells automatically. The
1014 latter used to resupply land units only.
1015 - Land units no longer have to be in supply to fire actively, for
1016 consistency with other ways to fire.
1017 - Submarines with zero mobility can no longer interdict, for
1018 consistency with other ways to torpedo.
1019 - Fix bugs that let submarines without capability torp use
1020 torpedoes to return fire and interdict.
1021 - Fix torpedo command not to require a line of sight for return
1022 fire and depth charges, and to use torpedo range instead of
1023 firing range for return torpedoes.
1024 - Active fire and interdiction didn't work for ships with zero
1025 firing range, even though return fire and support did. No such
1026 ships exist in the stock game.
1027 - Let land units with zero firing range and non-zero firing damage
1028 fire, for consistency with ships. No such units exist in the
1030 - Ships required different numbers of military to operate their
1031 guns for the various kinds of fire. Unify to require 2*N-1
1032 military to fire N guns.
1033 - Ship ammunition use differed for the various kinds of fire.
1034 Unify to use one shell per two guns.
1035 - Forts could fire support even when there were not enough mil.
1036 - Fix automatic shell resupply in several places to supply exactly
1037 the shells actually fired, no more, no less.
1038 * Change depth charges back to how they are documented and worked
1039 before 4.0.6, mostly: require no guns, one military, do damage like
1040 shell fire from three guns (before 4.0.6: two guns), use two
1041 shells. In 4.0.6's model, they worked exactly like shell fire
1042 (require guns and gun crew, non-zero firing range, damage and
1043 ammunition use scales with available guns), except for missions,
1044 which was a bug. Note that depth charge damage for all ships is
1045 now like fire from three guns for two shells. No change for dd; af
1046 did two gun damage for one shell before, and nas did four gun
1047 damage for two shells.
1048 * The edit command keys deprecated in 4.3.3 are now gone.
1049 * Fix build not to screw up automatic dependencies on certain compile
1051 * Fix a bug that could prevent repeated news from properly
1052 aggregating into one news item.
1053 * Properly initialize all bits in game state files, even those that
1055 * Fix explore's test for stopping on a splashed bridge. The bug made
1056 explore print to a bogus message.
1057 * Fix spelling of symbol airburst in table plane-flags. This could
1059 * Change designate not to check total cost before executing the
1060 redesignation. The code implementing that was buggy and too ugly
1061 to live. Designate doesn't cost anything in the stock game.
1062 * Always charge land units at least as much mobility for assaulting
1063 from non-landing ships as from landing ships. Before, marines lost
1064 all mobility when assaulting from a non-landing ship, which could
1065 be less than what the same assault costs from a landing ship (half
1067 * Fix LWP's stack initialization for -s. It caused crashes on some
1069 * Fix confused and buggy bridge splashing code:
1070 - Flying planes could be reported drowned.
1071 - Pin-bombing a bridge head failed to collapse bridge spans for
1072 lack of support, unless the pin-bombing caused collateral damage.
1073 - Corrupt sector file could lead to infinite recursion.
1074 * Relative names now work for econfig keys data and info.
1075 * Fix utility programs to abort on internal errors. They used to
1076 print a message and attempt to recover.
1077 * Fix off-by-one in fairland that ate the last expansion island.
1078 * Switch from CVS to git.
1079 * Code refactoring and cleanup.
1080 * Portability fixes.
1081 * Info file, manual page and documentation fixes and updates.
1083 Changes to Empire 4.3.11 - Tue Jan 1 18:57:38 UTC 2008
1084 * New sector selector elev. It's set by fairland, but has no effect
1085 on the game. It can be useful for deities to customize a world
1086 created by fairland.
1087 * The client now copes with ids greater than 15. The Empire
1088 protocol currently uses 14 ids.
1089 * Rewrite the client's code for reading server output during login.
1090 The old code could write one byte beyond the end of the buffer
1091 (theoretically a remote hole), got confused by long lines, and
1092 lines that didn't arrive in one piece.
1093 * Long country name, password or user name crashed the client.
1094 * Fix xdump not to deny access to game state tables when maximum
1095 minutes per day are exceeded.
1096 * The server considers a country bankrupt when its treasury is
1097 negative. Except when it doesn't. Fix that:
1098 - report misreported countries with $0 as broke.
1099 - If a command spent a few cents more than you had, commands requiring
1100 money became unavailable even when rounding brought you back to
1101 $0. But logging out and back in then bankrupted you.
1102 - If your treasury rose to exactly $0, commands requiring money
1103 remained unavailable.
1104 - If you had $0, sectors didn't build and sectors and ships didn't
1105 produce at the update.
1106 * Fix a bug in trade that made your money evaporate when a trade fell
1107 through because you couldn't fully pay. This bug was there since
1108 the introduction of the market in 4.0.0. It got aggravated by the
1109 removal of forced loans in 4.3.0.
1110 * Fix printing of the new group in army, fleet and wing. Broken in
1112 * Fix flash not to screw up the message when the first argument
1113 contains white-space.
1114 * Don't let planes intercept when they are stuck in foreign bases, on
1115 inefficient ships or land units, or on land units loaded on ships
1117 * Fix a bug that made interception require petrol to be present even
1118 for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
1119 defense missions weren't affected.
1120 * fairland and setsector now limit fertility to 100 instead of 120,
1121 like the other resources.
1122 * Generalize the autonav hack for fishing boats so it covers oil
1124 * Fix bug in path command that made it swallow every other step.
1126 * The execute command no longer supports redirections and execute in
1127 batch files. Flaws in the Empire protocol make it next to
1128 impossible for clients to implement that correctly. See
1129 doc/clients-howto for an explanation.
1130 * Rewrite much of the client's code for sending commands and
1131 receiving server output:
1132 - No longer blocks on sending commands, which could deadlock the
1134 - Fix race condition that could cause server output to be discarded
1135 on EOF on standard input.
1136 - Don't discard server output when reading standard input fails.
1137 - Fix error handling for execute and other, more obscure cases.
1138 - More rigorous error checking for redirections and execute.
1139 Clearer error messages, too.
1140 - Fix execute redirected to file or pipe. Believed to be broken in
1142 - The client now creates files for redirections with the same
1143 permissions whether the redirection is in a pipe or not. Before,
1144 redirections without a pipe created files with no permissions for
1145 group and others. This change may make your redirected output
1146 visible to other users on your system. Use the usual controls,
1147 like umask, to restrict permissions to your liking.
1148 - Reject unexpected redirections (violating the protocol). Before,
1149 they silently replaced the current one, and in the case of pipes
1150 leaked file descriptors and memory.
1151 - Redirections in batch files are not implemented. They didn't
1152 quite work before, and could leak memory and file descriptors. A
1153 flaw in the Empire protocol makes them next to impossible to
1154 implement correctly.
1155 - The execute command in batch files is not implemented. A flaw in
1156 the Empire protocol makes this practically useless anyway.
1157 - Old code leaked memory in various places.
1158 - Unfortunate incompatibility with older servers: if you type the
1159 EOF character (normally ^D) at an argument prompt, the session
1160 hangs. Use the interrupt character (normally ^C) to get out.
1161 * The client now supports options -h and -v.
1162 * The client no longer zaps its command line in a lame attempt at
1163 protecting users who foolishly specify passwords on the command
1164 line. Zapping annoys system administrators and creates a false
1166 * Journal entries are now flushed to disk right away when the server
1167 is running in debug mode.
1168 * Fix bugs in load that could make loading operations fail noisily
1169 instead of silently on some systems.
1170 * Server now reliably shuts down session when it receives an
1171 end-of-file condition from the client. Before, it merely failed
1172 the current command when it got it at an argument prompt.
1173 * Fix bug in execute that could crash the server on some systems when
1174 it prompts for the argument.
1175 * Fix bug that let you check whether a non-allied carrier is
1176 efficient enough for takeoff when one of your planes got stuck
1178 * Fix bug that let you attempt to escort a one-way mission to a
1179 carrier with non-light, non-interceptor escorts. Such planes don't
1180 fit on carriers, and the command then failed with a bogus error
1181 message. Before 4.2.17, the planes flew, and the escorts were
1183 * Change the rules for fitting planes on ships slightly, so that the
1184 order of loading no longer matters. Choppers and x-lights can now
1185 use plane slots even when not light. X-light choppers, which don't
1186 exist in the stock game, can no longer use x-light slots.
1187 * The server now keeps its log file open, just like the journal.
1188 * New server option -R to set the PRNG seed. This is for
1189 reproducible tests. Change the Windows-only service uninstall
1190 options from -r/-R to -u/-U.
1191 * Supply a real PRNG for Windows instead of the leaky water-pistol
1193 * Threads sleeping until a specified time could return early under
1194 Windows. This could cause missed updates. Broken in 4.3.10.
1195 * Fix missing newline in show updates.
1196 * Power report didn't factor tech into power correctly. Broken in
1198 * Code refactoring and cleanup.
1199 * Info file and documentation fixes and updates.
1201 Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
1202 * Bridge spans now cost $1000 instead of $2000, and bridge towers
1203 $3000 instead of $7500.
1204 * The Windows port now supports IPv6, but it still needs to be
1205 enabled manually at compile-time.
1206 * The custom table reader detects more errors.
1207 * Do not leak world creation time in files and fairland, because
1208 that facilitates attacks against the PRNG. This misfeature crept
1210 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
1211 Using it required manual hackery since 4.3.0.
1212 * Plug file descriptor leak in add command.
1213 * Don't kill player connections violently when their thread appears
1214 to be hung. Threads being aborted by update or shutdown could be
1215 misidentified as hung, and the violence could lead to resource
1216 leaks, locked out updates, and corrupted game state.
1217 * Fix LWP to reliably wake up threads sleeping for a time. Before,
1218 players with a sufficiently fast connection could starve out system
1219 threads, including the update.
1220 * Fix a class of bugs that made commands behave differently while the
1221 update is attempting to take control:
1222 - No MOB_ACCESS mobility was gained.
1223 - Telegrams were miscounted.
1224 - Bulletins got misfiled as production reports.
1225 - The navigate command ignored sail paths.
1226 - The declare command was more quiet, and declarations of war
1227 failed silently when SLOW_WAR was enabled.
1228 - Many messages got misdirected to bulletins.
1229 Some of these bugs go back all the way to Empire 2, ca 1995.
1230 * New deity command reload, effect similar to SIGHUP.
1231 * Not voting for a demand update no longer lets you veto further
1232 demand updates. This feature was flawed (it encourages players to
1233 vote late so that they can tactically vote no and thus build up
1234 veto rights), virtually unused, and buggy. The edit command still
1235 accepts and ignores the country key 'U' for compatibility, but it
1237 * Fix zdone not to claim to have triggered an update when they're
1239 * New update scheduler and ETU clock:
1240 - New schedule file. See doc/schedule for how to use it. Replaces
1241 econfig keys update_policy, adj_update, update_times, hourslop,
1242 blitz_time. A change of schedule does not require a server
1244 - The force command can no longer force updates in the future.
1245 Edit the schedule file for that.
1246 - New command show updates to show the update schedule. Obsoletes
1248 - New xdump game and xdump updates.
1249 - New utility program empsched to help test update schedules.
1250 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
1251 by econfig key update_demand.
1252 - econfig key update_demandtimes no longer applies to scheduled
1254 - You now receive new BTUs at the update in addition to login.
1255 - You now always gain the same BTUs and MOB_ACCESS mobility per
1256 turn, even when the update schedule changes, updates get missed,
1257 or unscheduled demand updates run.
1258 - Remove the mobupdate command, because porting it to the new ETU
1259 clock is not worth it.
1260 * Redesign of synchronization between commands, update and shutdown,
1261 and how updates are triggered:
1262 - Simplify update to a single thread waiting for the trigger.
1263 Before, three update threads had to perform a carefully
1264 choreographed dance to make updates happen. The dance relied on
1265 thread priorities for correctness, which are only implemented by
1266 LWP. With pthreads and under Windows, demand updates were prone
1267 to two update threads starting up concurrently. Even with LWP,
1268 forced and demand updates could lead to double updates.
1269 - Use a lock for synchronization: commands take it shared, update
1270 and shutdown take it exclusive. This makes update and shutdown
1271 block until all aborted commands terminated and gave up their
1272 lock. Before, they proceeded blindly after waiting two or one
1273 seconds respectively, which was cheesy and unsafe.
1274 - New commands no longer fail while the update is pending, they are
1275 delayed until after the update.
1276 - New commands can no longer start during shutdown. Before, they
1277 could, but risked getting killed violently, possibly corrupting
1279 - Fix command execution so that commands blocked in writing
1280 redirections are abortable. The bug allowed players to delay
1281 update and shutdown indefinitely.
1282 - Fix shutdown not to let player threads block on output. This
1283 let players delay shutdown indefinitely.
1284 - Fix reading of player input not to block again after update or
1285 shutdown aborted it. The bug allowed players to delay update and
1286 shutdown indefinitely.
1287 * Thread priorities are only implemented by LWP and no longer used.
1288 With LWP, they let players with a sufficiently fast connection
1289 starve out the threads that clean the lost file and kill idle
1290 connections. Drop them.
1291 * Show nuke rounded required research incorrectly.
1292 * Log unprintable characters as octal escapes rather than question
1293 marks in the journal file.
1294 * The files program no longer changes permissions of existing files.
1295 * The files program now creates all files with permissions ug=rw and
1296 all directories ug=rwx, modified by umask.
1297 * Fix a bug that could make arm, disarm and nuke detonation work with
1298 a used-up nuke instead of the armed one. This could be abused to
1299 detonate nukes multiple times. Broken in 4.3.3.
1300 * Fix nuke detonation output for zero blast radius.
1301 * Plug memory leaks in thread code.
1302 * Fix a bug that made LWP I/O wakeup unreliable.
1303 * New march sub-command v for view.
1304 * Journal was initialized before threads were, which was wrong.
1305 * Fix server not to create a journal on SIGHUP when it is disabled.
1306 * shutdown 0 now requests immediate shutdown instead of cancellation
1307 of a pending shutdown. shutdown -1 now cancels.
1308 * flash and wall no longer split long message lines.
1309 * Fix a bug in collect that screwed up a fully collected loan instead
1310 of deleting it. The screwed up loan could not be sharked or
1311 collected, but it could be repaid.
1312 * Remove the wait command, it's been broken and restricted to deity
1313 since Empire 2, ca. 1995.
1314 * Budget failed to take sector production into account for predicting
1315 unit repairs. Before 4.3.6, this bug bit only when you fooled
1316 around with budget priorities.
1317 * When unit repairs are limited by materials, the efficiency gain is
1319 * Ship repairs outside harbors and plane repairs by carriers used to
1320 consume commodities when and as far as available. Now, they
1321 consume the same fraction of the real cost of each commodity,
1322 i.e. commodity use is limited by the most scarce commodity.
1323 Neither old nor new behavior make much sense, but the new code is
1325 * Code refactoring and cleanup, in particular to make the Windows
1327 * Portability fixes.
1328 * Info file and manual page updates. All manual pages are now
1329 installed in section 6.
1331 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
1332 * Fix declare to prevent the deity from changing relations for a
1333 player to self. Allow the deity to set the relations of a player
1335 * Fix arm not to put the same nuke on multiple planes (broken in
1337 * New option AUTO_POWER.
1338 * Sectors now repair allied land units.
1339 * Sectors now repair only own and allied planes.
1340 * Fix repair of planes on foreign carriers: repair allied planes,
1341 ignore the others. Before 4.3.3, carriers destroyed rather than
1342 repaired foreign planes. Since 4.3.3, foreign planes were treated
1343 as recoverable error.
1344 * Fix automatic fortification of land units to use all excess
1345 mobility even when mobility delta exceeds mobility maximum.
1346 * Disable automatic fortification of land units when MOB_ACCESS is
1347 on, because it is prohibitively slow then (broken in 4.2.13).
1348 * Budget now shows level production (tech, education, research and
1349 happiness) rounded instead of randomly rounded.
1350 * Fix update not to randomly flush small level production to zero.
1351 * Fix overly restrictive game file locking under Windows (broken in
1353 * Fix navigate to charge mobility for sweeping mines without moving
1357 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
1358 * Ships no longer produce stuff when the government is broke.
1359 * Fix land unit casualties in revolts.
1360 * Fix security units not to raid friendly che.
1361 * Fix update sequence to ensure stopped sectors don't work on the
1362 ships, planes and land units in the sector. Before 4.3.6, this bug
1363 bit only when you fooled around with budget priorities.
1364 * Fix canal loading (was broken in 4.3.0).
1365 * Fix tend not to tend land units that could not be loaded.
1366 * Make xdump command available before break, but deny access to game
1368 * Lock game files to prevent concurrent access by multiple programs.
1369 fairland does not yet obey the lock.
1370 * Fix production to consider sector item limit.
1371 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
1372 * Enhanced mapping sub-commands in move, test, explore and transport.
1376 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
1377 * Sanctuaries are again fully populated with civilians (4.3.6 changed
1378 the limit, but not the population). Food is now spread evenly
1380 * Fix path finder to find shortest naval and aerial paths again
1382 * transport's map sub-command now does the right thing for a unit
1384 * Fix bug in map sub-command of move, explore and transport that
1385 passed junk to map command. Could theoretically crash.
1386 * Food need reported by starvation was one short for sectors without
1388 * Change land unit ammunition use back to what it was before 4.2.3.
1389 This lets deities customize ammunition use independent of damage.
1390 It also substantially reduces ammunition consumption at high tech.
1391 * navigation and march enhancements:
1392 - Sub-command 'f' now takes an optional ship / land unit number.
1393 - Mapping sub-commands now take an optional ship / land unit
1395 - New sub-command 'd' to drop mines.
1396 * Let minesweepers retreat at their full speed (missed in 4.3.6).
1397 * SUPER_BARS cannot be harmed, so don't interdict them.
1398 * Don't let trains and non-trains march together for now, because the
1399 march code isn't prepared for that.
1400 * New mapping flag 'n' to show nukes.
1401 * Mapping flag '*' now shows nukes as well.
1402 * New command nbmap to bmap around a nuke. Overload command nmap to
1403 map around a nuke when given a nuke argument.
1404 * Fix an inconsistency that gave tactical bombers a small bonus
1405 vs. flak when pin-bombing.
1406 * Fix production to show the designation that actually produces, not
1407 the designation as it is now (broken in 4.3.6).
1408 * Fix accidental whitespace change in output of sdump, pdump and
1409 ldump that crept into 4.3.5.
1410 * Support user-defined sector types and products in custom tables,
1411 not just customization of existing ones.
1412 * Fix off-by-one bug in budget that used to be masked by budget
1413 priorities until their demise in 4.3.6. The bug could crash the
1414 game on certain systems.
1418 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
1419 * The shutdown command now terminates the server process correctly
1420 even with LinuxThreads pthreads under Linux 2.4 and earlier.
1421 * Cope with old versions of groff (broken in 4.3.0).
1422 * You can now arm allied planes with nukes.
1423 * Taking a nuke off a plane gives it to the sector owner again.
1424 Feature was accidentally dropped in 4.3.3. Recipient must be
1426 * Naval path went bananas for impassable end sectors (broken in
1428 * New econfig key disabled_commands.
1429 * New territory selector dterr, restricted to deities. The territory
1430 command defaults to it for deities.
1431 * Let land units attack as long as they have positive mobility,
1432 except for high-mobility terrain (mountains), where the rules
1433 remain as they were: land units need to have all the mobility
1434 charged for the attack, not counting combat and moving in to
1435 occupy. Rationale: Making sure your land units reach attack
1436 positions with enough mobility left is a pain in the neck.
1437 Requiring only positive mobility is friendlier, but allowed rushing
1438 of mountains, so we make an exception there.
1439 * Can typeset info pages as PostScript. Result isn't exactly pretty.
1440 * Support disabling of infrastructure in infra custom table. Remove
1441 redundant option DEFENSE_INFRA. show command now shows only enabled
1443 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
1444 pmap sbmap, smap (broken in 4.3.1).
1445 * New, simpler sector mobility cost formula:
1446 - The basic cost is still a linear function of sector efficiency,
1447 with customizable cost at 0% and at 100%. The latter used to be
1448 derived from the former. The show command shows both parameters
1450 - Mountains are no longer a special case.
1451 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
1452 to 1.304, highway, bridge head, bridge span and bridge tower
1453 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
1454 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
1455 players can designate now cost the same at 0%. That's a feature.
1456 - Road infrastructure now reduces cost up to 90%, linear in road
1457 efficiency (used to be close to that, but non-linear). Same for
1458 rail infrastructure, but 99%. Adapted from Ice World V.
1459 - Double land unit minimum cost to 0.02, to slow them down on
1461 - Change land unit cost penalty in newly taken land to an extra 0.2
1462 instead of a minimum of 0.2, to reduce penetration depth.
1463 * Reduce bridge head defense and collect value to match highway's.
1464 * sinfrastructure displayed bogus rail mobility costs when there was
1466 * Retreating engineers took full landmine damage instead of half.
1467 * Fix socket creation code not to print a null pointer.
1468 * Fix login option code not to search beyond end of table (broken in
1470 * Spy planes and satellites can no longer spot landspies.
1471 * Spy planes can now spot surface ships at sea. They can no longer
1472 spot land units loaded on ships or land units.
1473 * Fix train retreat mobility cost, and don't permit retreat off rail.
1474 * Change maximum population to 100 for plains (was 49), mountains
1475 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
1476 the other habitable sector types (was 999).
1477 * Let minesweepers navigate at the speed their stats indicate by
1478 letting them sweep on the move at no extra mobility charge.
1479 * Reduce chance for planes to abort from 100-eff (if eff<80) to
1480 80-eff. This should make it easier to punch through air defense,
1481 flak in particular, and increase the risk of getting shot down.
1482 * Ship and land unit flak intensity is now proportional to efficiency.
1483 * Ship and land unit flak intensity is no longer scaled by the tech
1484 of the owner of the last thing firing. It's still scaled by each
1486 * All ships and land units firing flak now spot the plane and are
1487 spotted by the plane. Previously, spotting stopped as soon as flak
1489 * Inefficient land units were overcharged mobility when reacting.
1490 Broken when Empire3 changed land unit mobility use not to depend on
1491 efficiency, except for supply units.
1492 * New journal file to log complete player input plus selected
1493 important events. Controlled by new econfig key keep_journal, off
1495 * Fix unsafe shutdown on SIGINT and SIGTERM.
1496 * Fix land unit path finding: paths weren't always cheapest (broken
1497 in 4.0.2), and trains could be sent down paths without rail (never
1498 worked). Also fixes unit reaction path cost.
1499 * The custom table reader can now deal with sector, item, product and
1500 infra tables more comfortably.
1501 * Remove option BIG_CITY. Deities can customize the sect table to
1502 get the same effect.
1503 * Many more selectors can now be compared with names, not just
1504 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
1505 not fully work for queer names like &&&.
1506 * Let land units on missions support, just like ships.
1507 * Don't let units loaded on a train react.
1508 * Change update sequence to repair ships, planes and land units after
1509 sectors produce. This makes repairs use new avail instead of old.
1510 * Let players stop and start units.
1511 * Remove budget priorities.
1512 * Make plane report easier to understand.
1513 * Change land report to show carriers in the same format as plane and
1516 * Info file and manual page fixes.
1518 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
1519 * In conditionals, ~ compared to a string selector now stands for an
1521 * Change encoding of `not in any group' from " " to "". This makes
1522 fleet=~ work. It also affects xdump.
1523 * Fix plane capture code to clear wing.
1524 * People now eat and starve exactly the same in sectors, ships and
1525 land units. There used to be small differences, and civilians and
1526 uw loaded on land units didn't eat at all. The starvation command
1527 has been updated accordingly.
1528 * Fix bug that makes it impossible to assault or board with land
1529 units (broken in 4.3.4).
1532 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
1533 * Don't use non-portable groff features (broken in 4.3.0).
1534 * Work around potential crash bugs in command argument access.
1535 * Plug major information leak through nation selectors (broken in
1536 4.2.21). The fix unfortunately exchanges the meaning of xdump
1537 nation and xdump country. Sorry about that.
1538 * Minimize redundancy between (mortal's) xdump nation and xdump
1540 * New nation selector rejects.
1541 * xdump nation now shows foreign relations and no longer discloses
1543 * Fix crash bug in edit.
1544 * Fix number of planes building in budget command (broken in 4.3.3).
1545 * Selectors group, fleet, wing and army are now strings, and obvious
1546 syntax like fleet#a works. xdump also shows the strings now.
1547 Units not assigned to a group currently have group string " ", but
1548 that may still change.
1549 * Don't fold conditionals to lower case, because it breaks valid
1550 conditionals like fleet#A.
1551 * Mobility cost of a plane sortie is no longer limited to current
1553 * Various formulas no longer truncate or round intermediate results.
1554 * Interdiction mission charged twice the normal mobility cost for
1556 * Fix sail not to interpret negative x-coordinates as unsail
1558 * Improved configure script.
1561 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
1562 * power c can now show powerless countries. power c * works.
1563 * Fortresses now require 5% efficiency to return fire and interdict.
1564 * Range of ship return fire and support fire no longer depends on
1566 * Fix heap smash in login command client. Remote hole!
1567 * Properly destroy nukes on collapsing bridges. Before, you could
1568 rescue them by building a new bridge or arming them on naval
1570 * Nukes are now numbered like other units:
1571 - New selector type replaces selectors number and types.
1572 - New selector plane points to plane armed with this nuke.
1573 - New selectors effic, mobil, tech, group, opx, opy, mission,
1574 radius. Provided because all units have them; values are
1575 currently not interesting.
1576 - nuke command output redesigned.
1577 - ndump output changed subtly: nukes are no longer sorted by
1578 location, nukes in the same location no longer share id, and
1579 nukes on planes are shown.
1580 - transport nuke now works like transport plane.
1581 * arm and disarm now accept the common plane syntax, not just plane
1583 * Fix arm to let you change an armed plane's air-burst/ground-burst
1585 * territory no longer re-prompts when supplied with a bad argument,
1587 * edit lets you edit stuff that is actually computed from other
1588 state, like sector's coastal flag. This makes no sense and is now
1589 deprecated. Stuff deprecated since 4.2.15 is now gone.
1592 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
1593 * Fix security units' raid at the update (broken in 4.0.0, fixed only
1594 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
1595 increase. Make sure empty units don't kill anyone.
1596 * Fix bug in player_init(), which was most likely fatal on 64 bit
1597 hosts. Broken in 4.3.0.
1598 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
1599 * The order in which sectors were visited for `*' arguments disclosed
1600 the real origin, fix. Mapping commands used to work around this
1601 bug, until 4.3.1 exposed it there as well.
1602 * Code didn't compile on some systems.
1603 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
1605 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
1606 * Fix check of game state on server startup (new in 4.3.0).
1607 * sail now accepts a destination sector.
1608 * Tend could send bogus bulletins (broken in 4.3.0).
1609 * Plug memory leaks in mission command.
1610 * Close loophole in navigate that allowed players to find all sectors
1611 that are unfriendly or inefficient harbors or bridges.
1612 * Server didn't start when default econfig was missing and user
1613 didn't supply one with -e (broken in 4.3.0).
1614 * Retreat condition 'h' (helpless) never worked, fix.
1615 * Fix retreating mine sweepers to use mobility for sweeping.
1616 * Fix retreating land units to hit mines with the same probability
1617 and to take the same damage as in normal movement. Before,
1618 hit probability was higher, and damage was lower.
1619 * Ships could retreat into sectors owned by whoever made them
1620 retreat, but not in their owner's sectors.
1621 * Fix 'm' at the movement prompt of transport and test.
1622 * Fix march and test not to apply conditionals to sectors mapped,
1623 which led to spurious error messages.
1624 * Fix break not to respect conditionals. The bug let players keep
1626 * Fix retreat code not to respect conditionals. Attackers could
1627 abuse this to suppress fleet and army retreat orders.
1628 * Fix retreat and edit to zero-terminate retreat paths.
1629 Theoretically abusable for gaining information.
1630 * Fix format string crash bugs in load, spy and bomb.
1631 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
1632 ~p before the first line of text never worked.
1633 * Fix ancient bridge building race condition that could break the
1634 test whether the player can afford the bridge.
1635 * Fix trade lot change detection in set command. Can probably be
1636 abused to defraud sellers.
1637 * The pthread code now compiles under Solaris.
1638 * navigate and march now permit any whitespace between route and
1639 optional argument for radar, lookout, sonar, not just spaces.
1640 * Fix canal navigation (was broken in 4.3.0).
1643 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
1644 * version no longer pretends option SHIPNAMES still exists.
1645 * Remove files auth and ban. They could be used to restrict client
1646 address and user. Restricting user is useless, because players can
1647 send whatever they want. Banning IPs is better done with a packet
1648 filter. That leaves restricting deity IPs. Provide new econfig
1649 key privip for that. Apply it to session kill as well as login.
1650 * xdump escapes GUINEA_PIGS status:
1651 - xdump is now enabled unconditionally.
1652 - xdump sect now dumps selector coastal, because it can't be
1653 reliably computed from other xdump information.
1654 - New xdump realm and country. Realm information is now stored in
1655 a separate file, with appropriate selectors.
1656 - Reviewed for completeness and information leaks. See info xdump
1657 for remaining issues. New treaty selector uid, nat selectors
1658 relations, contacts. Removed useless selectors: news and lost
1660 - Command syntax changed.
1661 - xdump opt is no more, option information is now in xdump ver.
1662 - xdump can now dump meta-data.
1663 - Header and footer changed to be more compact. You now need
1664 meta-data to identify fields.
1666 - Documentation in doc/xdump.
1667 * New econfig key builtindir.
1668 * New econfig key custom_tables lets you customize configuration
1669 tables without recompiling. Customizing tables other than unit
1670 tables is not recommended for now. See doc/econfig for
1672 * Check configuration and game state are sane on server startup.
1673 * Remove option NONUKES and NEUTRON. Deities can load a suitable
1674 nuke table to get the same effect.
1675 * Remove option DRNUKE. Use econfig key drnuke_const to control
1676 whether nukes need research.
1677 * Disqualify land units from performing missions while loaded on
1679 * Fix dump for strings without terminating zero.
1680 * Fix login command option not to send an extra prompt.
1681 * zdone now displays information about demand update vetoing.
1682 * The Windows port now requires Winsock version 2.
1683 * Remove econfig key powe_cost.
1684 * version report now shows all the configurable settings of interest
1686 * carg and lcarg now display people as well.
1687 * ldump now dumps civ and uw as well.
1688 * Fix dangling pointer dereference in dogfighting code.
1689 * Tell sector owner when partisans take over. But don't disclose che
1691 * emp_server, files, fairland now support options -h and -v.
1692 * Simplify baroque version numbering to a single version number.
1693 This affects output of version.
1694 * New show item and show news.
1695 * New build process:
1696 - Follow the usual steps: configure; make; make install. The
1697 latter is optional. The only file deities still have to edit is
1699 - Use GNU Autoconf for system configuration.
1700 - Use GNU Make for portability and features.
1701 - Support separate build trees.
1702 - Remake out-of-date dependencies automatically.
1703 - Remake out-of-date info files automatically.
1704 - Flatten info directory.
1705 - Formatted info files are no longer distributed in source tarball.
1706 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
1707 low-level options doesn't seem to be worth the effort, as
1708 UCONTEXT should be pretty portable.
1709 * Fix use of freed memory in sail.
1710 * sail could let large ships enter big cities.
1711 * Fix reject and accept not to require contact.
1712 * Fix sharebmap and telegram to prompt for a missing first argument.
1713 * Fix report to align column research correctly for deities.
1714 * When the optional newspaper argument doesn't work because HIDDEN is
1715 enabled, complain instead of ignoring it silently.
1716 * When BLITZ is enabled, fairland no longer permutes country numbers
1717 in newcap_script so that start islands are ordered from top left to
1719 * Minimize output format differences between options:
1720 - census shows column fall regardless of FALLOUT.
1721 - show nuke now shows column res regardless of DRNUKE.
1722 - report no longer suppress column status when HIDDEN is enabled.
1723 HIDDEN limits status information like for the country command.
1724 - relations column width differed depending on option SLOW_WAR.
1725 Always use the wider format.
1726 * Fix a bug in edit that suppressed the player notification telex on
1727 military reserve change.
1728 * Fix command dispatch not to let deities use commands that are
1729 declared not to be available to them. The only command affected is
1731 * Fix the list command for visitor.
1732 * econfig key m_m_p_d no longer applies to deities.
1733 * Fix the origin command for country #0. Allow moving origin to
1734 another country's origin. Allow deities to reset origin to
1735 absolute 0,0. This turns origin into a superset of the offset
1736 command. Remove offset command.
1737 * Fix a bug that caused unpredictable flak damage when it should have
1738 been maximum damage (was broken in 4.2.19).
1739 * Don't store initial capital location, remove the associated nat
1740 selectors xstart, ystart.
1741 * Fix production command to consider resource depletion.
1742 * Fix justification of coordinate output in cutoff and mission.
1743 * Option UPDATESCHED is no longer optional. Disabling it didn't
1746 * Turn options into ordinary econfig keys.
1747 * New econfig key start_cash.
1748 * BTU regeneration now depends on the capital's work percentage.
1749 * nation now supports an optional argument that lets deities ask for
1750 somebody else's nation report.
1751 * Fix nation to display SANCTUARY instead of VISITOR for countries in
1753 * Fix capital to let you use a regained sacked capital without
1754 activating another one in between.
1755 * Don't move capital when it is sacked.
1756 * New ship capability canal, replacing obscure formula based on build
1758 * You now need a capital to request a demand update.
1759 * power now ignores landspies.
1760 * Fix LWP stack checking.
1761 * Clean up LWP, drop dead machine-specific code, fix portability bugs
1763 * census now shows the old owner instead of `*'. dump is unchanged
1764 to avoid breaking clients.
1765 * peek no longer prints the old owner.
1766 * When a bombed land unit retreated, collateral damage was applied to
1768 * paradrop, drop and fly can no longer abandon the base sector.
1769 * Tending foreign ships now sends a bulletin to the owner.
1770 * Fix bug that permitted login for inactive countries, including ""
1771 * Fix tend for spies.
1772 * Change launch to fire all missiles selected at the same target.
1773 Previously, it prompted for a new target after each missile.
1774 * add, consider, build, launch and fire no longer re-prompt when
1775 supplied with a bad argument, they just fail. Consequently, the
1776 build command no longer lets you list types you can build. It
1777 points to the show command instead.
1778 * Fix add not to truncate country number.
1779 * Fix selector coastal to be accurate at all times.
1780 * Fix obscure bug in fairland: the sector added last to an island
1781 wasn't considered coastal. Affected resource computation.
1782 * Fix sector wiping in add command.
1783 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
1784 ways. Custom configuration tables should become a serviceable
1785 replacement eventually.
1786 * Client no longer freezes on long lines of server output.
1787 * Fix uninitialized signal mask bugs.
1788 * Fix Windows service code's treatment of -e.
1789 * Sub interdiction disclosed sub owner through news' actor selector.
1790 * country reports on all countries, but carefully limits information
1791 disclosed to mortals. Output format changed.
1792 * Market no longer forces sellers to grant loans.
1793 * Fix potential crash bug in set command. Friendlier prompt and
1795 * Substantial code cleanup and portability fixes.
1796 * Extend empfile abstraction to cover game configuration.
1797 * Overhaul of game state storage.
1798 * The above includes major contributions from Ron Koenderink. Many
1801 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
1802 * Make version pretend option SHIPNAMES still exists, for the benefit
1803 of clients that still depend on it.
1804 * The change to conv in 4.2.22 could crash or compute incorrect
1806 * Info updates missing in 4.2.22.
1807 * A few code cleanups.
1809 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
1810 * Log player login, logout and session kill.
1811 * Close loophole in assembly point rules that allowed players to find
1812 all unowned sectors. The assembly point must now be owned by you
1813 or an ally, or you or an ally must have a ship there.
1814 * Don't let embarked land units fire flak.
1815 * Fix display of the last connection's host when the host name was
1817 * Fix change command to accept full length representative (password),
1818 currently 19 characters. It used to chop off after eight
1820 * Non-recon missions no longer establish contact to owners of
1821 overflown sectors, because those missions do not identify the
1822 owner. This matches info Hidden.
1823 * The following events now establish contact:
1825 - Sighting a ship when toggle coastwatch is off
1826 - Spotting overflying planes
1827 - satellite spotting land units
1828 - lookout and llookout spotting ships, planes and land units
1829 - Any relations change
1830 * The country command's `temporary' state of disorder ended after
1832 * Telegram notifications could get lost in exotic circumstances,
1833 e.g. while a second client attempted to connect. Can be abused for
1835 * Remove option SNEAK_ATTACK.
1836 * Fix lboard not to let you board dead land units.
1837 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
1839 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
1841 * Fix fly to let the player abort the command at the last prompt.
1842 * Client no longer reads execute scripts in binary mode under
1844 * New econfig key listen_address.
1845 * econfig key port can now be a service name. Service empire no
1846 longer takes precedence over econfig.
1847 * Client falls back to compiled-in host only if environment doesn't
1848 supply one, not if it can't be resolved. Same for port.
1849 * Oil derrick could extract slightly more oil than was in the ground.
1850 * test command checked start sector for space and some other things
1851 instead of end sector.
1852 * convert now silently limits conversions to avoid exceeding maximum
1854 * shoot no longer limits you to 999 victims.
1855 * 4.2.19 broke pin-bombing commodities on some platforms.
1856 * Don't block on output while update is pending. This is required to
1857 ensure the update can abort commands.
1858 * Commands submitted while the update is waiting for commands to
1860 * The force command no longer waits for the specified time. It
1861 starts a scheduling thread instead, just like shutdown.
1862 * Correct grammar and punctuation in output of version.
1863 * Option SHIPNAMES is no longer optional.
1864 * Fix output of qorder and sorder for ships with sail path.
1865 * Don't change capital to agribusiness on retake. From Pat Loney.
1866 * bdes prompt for new designation was messed up for empty bmaps.
1867 * Client now supports pipes under Windows.
1868 * Care for subtle Windows socket incompatibilities.
1869 * Fix strength command not to lie about units reacting into
1871 * strength now yields the processor periodically, to keep the game
1873 * Schedule commands more fairly. Previously, a sufficiently fast
1874 player could starve out the others.
1875 * launch assumed plane maximum mobility 127 for calculating when
1876 satellites will be ready to use.
1877 * Drop support for for DCE threads.
1878 * Drop support for pthread implementations lacking pthread_kill().
1879 This includes ancient versions of OS X.
1881 * Minor info file fixes.
1882 * The above includes major contributions from Ron Koenderink. Many
1885 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
1886 * Don't let threads block on output to another player thread's
1887 socket. Such blocking violates basic design assumptions and can
1888 cause all kinds of grief. In particular, it causes player session
1889 hangs under Windows with 4.2.20. Broken since the introduction of
1890 flash and asynchronous telegram notification many years ago.
1891 * Threads sleeping until a specified time could return early under
1892 Windows. This could cause double-updates.
1893 * Fix fallout damage (was broken in 4.2.19).
1894 * Fix show sector s (was broken in 4.2.19).
1895 * Fix deliver not to deliver friendly civilians into occupied
1897 * Fix mil duplication in board (was broken in 4.2.14).
1898 * Fix stack smash in lrange, shoot and execute. Remote holes, and
1899 the last one doesn't even require authentication.
1900 * Fix crash bug in emp_config parsing.
1901 * Fix buffer overruns in turn and shutdown.
1902 * Fix second argument of shutdown.
1903 * announce, pray, telegram and turn now abort on EOF.
1904 * Fix display of MOTD and game down message of maximum size.
1905 * Correctly support telnet line termination on input. Previously,
1906 carriage returns could slip into ship names and such.
1907 * Fix flash not to lie about recipients that are just logging in.
1908 * Remove obscure login command list.
1909 * Convert client from obsolete termcap to terminfo, and clean up
1911 * New fairland option -h to print usage information. Improved
1912 command line syntax diagnostics. Exit unsuccessfully on unknown
1914 * fleet and army now copy retreat orders of the fleet's or army's
1915 first member with group retreat orders in the same sector.
1916 Previously, they used the retreat orders of the first fleet or army
1917 member, which is less than useful, and failed to take ownership
1918 into account, which is an abusable bug.
1920 * Fix xdump not to disclose other countries' losses.
1921 * Fix exit status of files program when it can't create files.
1922 * Support UTF-8 encoded Unicode in human-human communications. This
1923 affects MOTD, game down message, telexes, announcements and flash
1924 messages. See new doc/unicode for technical details.
1925 * New login command `options' for client/server option negotiation.
1926 See new doc/clients-howto for technical details. The only option
1928 * emp_client -u now requests UTF-8. This requires a terminal that
1930 * Fix news for land unit defensive support.
1931 * Properly mark sea mines hit by retreating ships. Unmark mines
1933 * Fix diagnostics for unknown selector names in conditionals (was
1935 * Fix selector name clashes: rename ship selector mobquota to mquota,
1936 land selector for reaction range limit from rad to rmax.
1937 * Fix Windows services for relative file names on command line or in
1938 econfig (was broken in 4.2.20).
1939 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
1940 are now float. This gives deities finer control over maximum
1942 * Fix production command for sectors with 60% efficiency.
1943 * Improve syntax of read for deities.
1945 * Some info topic names differed only in case, which loses on
1946 case-insensitive file systems, and is a bad user interface even
1947 when it works. Change those names. Rename deity command hidden to
1948 peek because its info topic clashed with that of option HIDDEN.
1949 * Thanks to Doug Wescott sheep are finally covered properly in info.
1950 * Documentation fixes.
1951 * Much of the above was contributed by Ron Koenderink. Many thanks!
1953 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
1954 * When units in different sectors marched, only units in the sector
1955 with the highest-numbered unit were interdicted. A marching
1956 non-spy made all marching spies visible to interdiction regardless
1958 * Fix crash when interdiction sinks second ship in a sector. Broken
1960 * Fix an ancient bug in simulation of level production that clobbered
1961 stack and could lead to low predictions, typically zero, which
1962 screwed up budget. The bug had no effect until 4.2.19.
1963 * When a sector revolts, and there wasn't enough space to liberate
1964 all uw, the number of remaining uw got the wrong sign. Broken in
1966 * Log and abort when LWP stack check detects stack smash. Server
1967 option -s no longer implies -p.
1968 * The native Windows build now supports -p and -s.
1969 * The native Windows build now properly deals with ^C when running in
1970 the foreground. It no longer prompts for a quit command on the
1972 * The meaning of server option -D in presence of -e is unclear.
1973 Other programs only support -e. Remove option -D. Use -e
1974 DIR/econfig instead of -D DIR.
1975 * New server option -v shows version information.
1976 * Fix the server's exit status with -h. Broken in 4.2.19.
1977 * The linux-pthreads build failed to shut down on signals.
1978 * Fix threading bugs in the native Windows build that made shutdown
1979 unsafe and screwed up update aborting commands.
1980 * New econfig key pre_update_hook to allow automatic, safe backup
1981 right before the update. See scripts/backup for an example.
1982 * The server now prints log messages to stderr as well when running
1984 * Fix potential buffer overflows in logerror() and lwpStatus().
1985 * Server now requires POSIX signals. It no longer catches SIGUSR1.
1986 * Remove support for ancient versions of HP-UX.
1987 * Fix seeding of PRNG broken in 4.2.19.
1988 * Don't reseed the PRNG in commands, it hurts randomness and could be
1989 abused by crafty players.
1990 * The server now makes the data directory its working directory.
1991 This also gets rid of a bug that changed the file name of the
1992 sector, power, nation and lostitems file unless econfig could not
1994 * The server now writes a pid file. Thanks to Daniel O'Connor.
1995 * More user friendly server startup: more errors are detected while
1996 the server still runs in the foreground, which makes it possible to
1997 complain to stderr and to exit unsuccessfully.
1998 * Early log messages went to the log file in the default data
1999 directory, even though econfig specifies another data directory.
2000 * Specifying an econfig file on the command line that can't be read
2002 * Errors in econfig are now fatal.
2003 * The server now refuses to start when it can't open data files.
2004 * News are now sorted and expire sanely.
2005 * Conditionals can now compare strings as well.
2006 * Corrupted down and motd files could cause buffer overflows.
2007 * Fix recon to let player abort at the flight path prompt.
2008 * power no longer rounds worldwide numbers for deities.
2009 * power command failed to recognize deities with non-zero country
2011 * Change output of production command so that columns are aligned
2012 even for large values. Replace column wkfc by more useful column
2014 * neweff and production miscalculated work when mil exceeded
2016 * neweff miscalculated work when the population limit exceeded 999.
2017 * Fix capping of avail when a big city is torn down.
2018 * Fix a bug in fire that allowed players to find all submarine uids.
2019 * Maximum sector population is no longer hardcoded, and now covered
2020 by xdump. Option RES_POP now affects mountains and plains as
2021 well. From Ray Hyatt.
2022 * Fix fina and news not to ignore errors in conditions.
2023 * The native Windows build now requires Windows Sockets 2.
2024 * The native Windows build now supports multiple instances of the
2025 service. The ability to supply additional startup parameters to
2026 the service has been removed.
2027 * Implement fairland command line parsing under Windows.
2028 * Improved fairland and emp_server usage message.
2030 * Minor info file and documentation fixes.
2031 * Much of the above was contributed by Ron Koenderink. Many thanks!
2033 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
2034 * Fix order not to unload into full sectors.
2035 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
2037 * Fix distribute not to conjure up a civilian when importing
2038 civilians from a dist center that doesn't have any.
2039 * Fix flak to resupply no more shells than actually needed.
2040 * Fix rounding error in shoot that could result in more people shot
2041 than actually there.
2042 * Fix info and apro error handling. In particular, do not leak
2043 potentially sensitive information on the server to players.
2044 * info no longer shows a random matching page when the topic argument
2045 is ambiguous. Instead, it lists all matching topics.
2046 * Embarked land units and overflying planes no longer spot each
2048 * Fix show command to show only sectors that players can designate
2049 (was broken in 4.2.18).
2050 * Fix a rounding error in production command column `max'.
2051 * Fix production command for overpopulated mountains and plains.
2052 * Fix tradeship ally cut to match documentation.
2053 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
2054 * Fix a bug in aerial sonar where ships could mask submarines with
2055 the same number modulo 256.
2056 * Don't allow bombing of subs that were not detected.
2057 * MOTD and the game down message are now entirely separate: use `turn
2058 motd' for the MOTD, and `turn on' and `turn off' for the game down
2059 message. `turn on' no longer lets you edit the MOTD.
2060 * Remove option NUKEFAILDETONATE.
2061 * Option ORBIT is no longer optional.
2062 * New option GUINEA_PIGS to control experimental stuff not ready for
2063 prime time. If your deity enables this in a serious game, run!
2064 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
2065 * New ship and land selectors rflags, rpath.
2066 * New ship selectors for order: xstart. xend, ystart, yend,
2067 cargostart, cargend, amtstart, amtend
2068 * New ship selectors for sail: mobquota, path, follow.
2069 * New news selector uid.
2070 * Implement command line parsing under Windows where it was missing.
2071 * emp_server and and files print a usage message on command line
2073 * Fix how emp_server exits after being panicked by a signal. It can
2074 now dump core when this happens.
2075 * Fix bug in client that could crash it when a line of input starts
2077 * Client now gets user name from environment variable LOGNAME if set,
2079 * The native Windows build can now run as a service.
2080 * Redirecting client input now works under Windows.
2082 * Don't confuse work with loyalty in info Citizens.
2083 * Minor info file and manual page fixes.
2084 * Much of the above was contributed by Ron Koenderink and Marc
2085 Olzheim. Many thanks!
2087 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
2088 * Fix info to accept abbreviated arguments under Windows. From Ron
2090 * Buying planes or land units loaded on something didn't work when
2091 that something moved.
2092 * Fix a bug that could produce update cascades with update policy
2094 * Fix delivery and distribution to grant packing bonus only to
2095 efficient sectors, just like move. Previously, delivery ignored
2096 efficiency, and distribution behaved as if it were an efficient
2097 sector without special bonuses.
2098 * New sector selectors loyal, access; ship selectors radius, access,
2099 xbuilt, ybuilt, builder, name; plane selectors radius, access,
2100 theta; land unit selectors radius, react, nland, access; lost
2102 * Fix sector selectors che, che_target; plane selectors att, def;
2103 nuke selector types; treaty selector exp; news selector time;
2104 commodity selectors type, xbuy, ybuy.
2105 * Option PLANENAMES is no longer optional.
2106 * Ensure config parameter variables and their description in
2107 configkeys[] are consistent. Inconsistencies there caused bugs in
2108 the past. From Marc Olzheim.
2109 * Complain if econfig file can't be read.
2110 * Better messages for errors in econfig file.
2111 * Remove unused econfig keys hard_tech and last_demand_update.
2112 * New econfig key news_keep_days to configure news expiry.
2113 * New econfig key anno_keep_days to configure announcement expiry.
2114 * Fix announcement expiry. It leaked file descriptors and memory,
2115 and could corrupt the anno file. From Ron Koenderink.
2116 * New command xdump: experimental extended dump. Disabled for now.
2117 * Bankers no longer round down debts, and they collect interest for
2118 the time debtors are idling at sub-prompts.
2119 * Loan interest calculation was broken at the due date and after a
2120 last payment made at the due date. With luck, debtors could abuse
2121 this to repay loans cheap (they couldn't gain cash, though), sharks
2122 to purchase loans cheap, and creditors to collect excessively.
2123 * Fix major bug in transport that allowed two cooperating countries
2125 * Don't report interdiction damage twice when transporting planes.
2126 * Fix message for attempting to transport a plane in a sector not
2127 owned by the player.
2128 * Fix confusing diagnostics when refusing to improve defense because
2129 option DEFENSE_INFRA is off.
2130 * Simplify confusing code in budget.
2131 * Fix spacing in output of budget and show.
2132 * Change one-way plane sorties to match ordinary sorties: offer
2133 carriers regardless of the sector they're in, require carriers to
2136 * Don't print owner of incoming missile twice when intercepting it.
2137 * Simplify constituent storage in product characteristics.
2138 * Replace remaining `variables' leftovers; mainly in unit
2140 * Remove leading spaces in deity unit dumps.
2141 * Replace inappropriate uses of compile time constant ETUS by 60.
2142 Deities don't change ETUS, they change etu_per_update by editing
2143 econfig. This nonsense dates back at least to chainsaw 3.31.
2144 * Change ship production (fishing and drilling for oil) to match
2145 sector production. Ship efficiency and tech are now relevant, and
2146 all people on board work. From Ron Koenderink.
2148 * Minor info file fixes.
2150 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
2151 * Fix seeding of PRNG under Windows. The bug made updates occur at
2152 a predictable time in the update window. From Ron Koenderink.
2153 * Close major loophole in drop that allowed players to determine
2154 whether an arbitrary sector is sea, allied land, or other land.
2155 * fly could fly civilians into occupied sectors. For consistency
2156 with other means to move around stuff, this is no longer possible.
2157 * Don't allow flying to a carrier that doesn't have space for the
2158 planes. Previously, planes that did this were teleported home,
2159 which could be abused.
2160 * Close loophole in bomb that allowed players to find all
2162 * Fix move and explore not to crash when moving civilians to a sector
2163 without civilians, and interdiction destroys them all. Found and
2164 debugged by Jeff Cotter.
2165 * Fix printing of messages entered with turn command. '%' characters
2166 could cause havoc, even crashes.
2167 * Use sector's actual maximum population to compute chance of plague
2168 outbreak. Previously, code used 9999 for big cities and 999 for
2169 other sectors, and info Plague said 999. This makes all crowded
2170 sectors equally vulnerable, even mountains, plains, and inefficient
2172 * Oil derricks no longer drill and deplete more oil than they can
2173 hold. From Ron Koenderink.
2174 * Version 4.2.15's coordinate and list parsing fixes reject trailing
2175 junk. That's too strict. Silently ignore trailing junk as long as
2176 it starts with whitespace.
2177 * Version 4.2.15's selector rewrite broke some type literals,
2178 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
2179 type literals to selectors.
2180 * Nightly build patches game to get repeatable PRNG results. From
2183 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
2184 * Previous version broke sector production when part of the work is
2185 used for sector construction. Fix courtesy Jeff Cotter.
2186 * Add rudimentary tests to nightly build. From Marc Olzheim.
2188 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
2189 * test command no longer asks whether to abandon the sector.
2190 * explore command could generate a bogus `lost' record when it
2191 regains an abandoned start sector.
2192 * edit command now properly updates stats when editing tech level of
2193 ships, planes or land units. A few of these stats can be edited
2194 separately, which doesn't make much sense, and is now deprecated.
2195 * edit command no longer accepts efficiency values that would destroy
2196 the edited unit. Deities can still delete units by setting the
2198 * upgrade command used to charge an amount of avail that didn't match
2199 info upgrade. Neither the implemented nor the documented amount
2200 made much sense. Change it to 15% of the full build cost. Rewrite
2202 * Commands upgrade and build could be off by one when reporting
2204 * upgrade command reported rounded cost but charged unrounded
2205 cost. Round cost of upgrade down to match behavior of build.
2206 * Upgrading planes now preserves range when it is less than the
2207 maximum range. It used to set it to the new maximum range.
2208 * show bridge and show tower no longer claim bridge building requires
2209 `workers' (whatever that is), since it doesn't.
2210 * Replace option ROLLOVER_AVAIL by econfig parameter
2211 rollover_avail_max, which is the maximum amount of avail that rolls
2212 over. Previously, avail was limited after rollover, and even when
2213 ROLLOVER_AVAIL was off. Fix that.
2214 * Ships weren't always charged mobility for firing with option
2216 * Fix shell use of return torpedoes.
2217 * designate no longer complains twice about deity only designations.
2218 * Ensure designate zaps efficiency only when sector type really
2220 * Fix strength to always report mines to deities.
2221 * Remove option SHIP_DECAY.
2222 * Fix bug in sonar that could crash or yield unpredictable results
2223 near the true origin.
2224 * Fix buffer overflow in flash and wall.
2225 * Fix wall not to strip out first word of message.
2226 * Change market and order to use item types instead of mnemo
2227 characters internally.
2228 * Market now reports sales with full item names instead of single
2230 * buy now requires first argument to be an item name, as documented.
2231 * production command handled production backlog incorrectly, failed
2232 to limit production for production efficiency greater than one,
2233 e.g. agribusiness, and incorrectly limited raw material
2234 consumption. Also fix a rounding error. With help from Ron
2236 * Sector work was accidentally truncated to even.
2237 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
2238 don't divide SHRT_MAX+1.
2239 * Properly diagnose over-long unit lists.
2240 * Rewrite selector code. Old code let players smash the stack by
2241 supplying too many conditions. New code properly rejects ambiguous
2242 abbreviations and prefers exact matches. Selectors with names that
2243 collide with types, like land units' rad and spy, now work.
2244 Selectors with non-integral values, like land units' att, now work.
2245 * survey used to display hundreds for everything but variables. Now
2246 it displays hundreds only for values that can be large.
2247 * Rewrite info survey. Document ability to survey properties other
2248 than items and resources.
2249 * Rewrite info build, since it was inaccurate and poorly structured.
2250 * Fix info fire on required military. From Marc Olzheim.
2251 * New fairland argument -R to set the PRNG seed. Print the seed.
2252 This allows you to recreate the same world again.
2253 * New facilities to deal with internal errors. These crash when the
2254 server is started with -d, which is appropriate for debugging, and
2255 potentially disastrous for running a real game.
2256 * Automated nightly builds.
2259 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
2260 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
2261 * Gripe about unknown options in econfig.
2262 * Remove option GRAB_THINGS.
2263 * Utility program files takes new option -f.
2264 * Remove utility programs land, ore and perfect, which don't compile
2265 since 4.2.0 (Oct '98).
2266 * fairland no longer warns when it added resources, but when it
2268 * Fallout code could claim destruction of more items than actually
2270 * Fix recursive resupply (resupply from supply land unit triggering a
2271 resupply of the land unit) when just testing for how much can be
2272 resupplied. The bug could have led to insufficient resupply.
2273 * Fix recursive resupply not to consume all fuel in supply units. No
2274 supply units consuming fuel exist in the stock game.
2275 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
2276 Distribution threshold were previously limited to 10000, and
2277 delivery thresholds to 65528.
2278 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
2279 used to limit to 9990. Market transactions and commands explore,
2280 move, drop and fly to 32767. Limiting in autonav code (order
2281 command) didn't work. Item delivery used to stop at 9990,
2282 distribution at 9999. Food growing and sector production used to
2283 stop at 9999. Grind, assault lunchboxes, demobilization, mine
2284 sweeping and che liberating uw could theoretically attempt to
2285 increase items beyond 65535, which would have been ignored
2286 (destroying the increase).
2287 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
2288 fallout increases behaved inconsistently. Increases beyond 65535
2289 could get ignored, or fallout could saturate at 9999, or it could
2290 overflow at 65536 (that would take quite some nuking, though).
2291 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
2292 operation that would have gone beyond 65535 was ignored.
2293 * Fix `are we loading or unloading' tests for load, unload, lload and
2295 * Fix editing of land unit attack and defense values. Implement
2296 editing of ship defense values. Contributed by Ron Koenderink.
2297 * edit now edits che number and target separately.
2298 * Fix edit to properly extend unit files. Contributed by Ron
2300 * Major internal reorganisation: Sectors need space for items,
2301 deliveries and distribution thresholds. To save space, the
2302 ancients invented `variables': a collection of key-value pairs,
2303 missing means zero value, space for `enough' keys. This
2304 complicates the code, as assigning to a `variable' can fail for
2305 lack of space. Over time, `enough' increased, and for quite some
2306 time now `variables' have been *wasting* space. Replace them,
2307 except in unit characteristics, where they are read-only, and will
2308 be replaced later. This also removes misfeatures like plague
2309 outbreaks silently deleting deliveries.
2310 * Remove disabled commands dissolve and mult. Remove configuration
2311 parameters minmult and maxmult.
2312 * trade command indexed an array out of bounds when attempting to
2313 display the plague as commodity. Fix.
2314 * New make goal interix. Contributed by Ron Koenderink.
2315 * The type selector now prefers an exact match to a partial match.
2316 ?type=sb now selects sb, not sbc, even when sbc happens to be found
2318 * Value of selector sell was always zero, remove it.
2319 * Clean up selector code.
2320 * satellite now displays all sectors owned by other players, and none
2321 else. It used to display all but sea, mountains, sanctuaries,
2322 wasteland and wilderness.
2323 * map commands now display wilderness and plains owned by other
2324 players as '?'. Radar commands now display all wilderness and
2326 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
2327 * Make client abort the current command on ^C under Windows, as
2328 everywhere else. Contributed by Ron Koenderink.
2329 * Command line parser interpreted trailing whitespace as an another
2330 (empty) argument. Ignore it instead.
2331 * Properly declare stuff in headers, include proper system headers.
2332 Remove all nested external declarations. Source code is now fully
2333 prototyped. Enable appropriate gcc warnings.
2334 * Fix several type errors. Some may have been show-stoppers on big
2335 endian machines where sizeof(long) != sizeof(int).
2336 * Remove pre-ISO C compatibility cruft (hey, it's been only fifteen
2338 * Various portability fixes. Some bugs may have been show-stoppers
2339 when sizeof(long) != sizeof(int). With help from Marc Olzheim and
2341 * Move some code to more logical places. Remove some unused code,
2342 some of which was hard to port.
2343 * The files program could print error messages to a log file in some
2344 circumstances. Make it print to stderr.
2345 * deliver can now change direction without changing the threshold.
2346 * deliver now provides appropriate context when prompting for
2348 * Login command play no longer ignores up to two arguments if there
2350 * Fix payoff (was broken in 4.2.13).
2351 * Capability fish didn't work together with capability oil.
2352 * Fix and clarify plague outbreak chance in info Plague.
2353 * Fix RES_POP maximum population in info Research.
2354 * Fix info telegram and info announce on ~ escapes.
2355 * Update info Selector to match code.
2356 * Document all undocumented unit capabilities and stats.
2357 * Document submarines' ability to carry landspies.
2358 * Fix info shoot on security units.
2359 * Various small info file fixes.
2360 * Many fixes in the troff macro package for info files.
2361 * Many fixes for translating info files to HTML.
2362 * Many info file markup fixes.
2364 Changes to Empire 4.2.13 - Fri Feb 13 22:12:36 UTC 2004
2365 * Source code reindented and cleaned up somewhat.
2366 * Various small info file fixes.
2367 * Fixed change requiring 254 BTUs even when not charging any
2369 * Fixed tactical non-marine missile crash.
2370 * Fixed spy unit detection chance for eff<100.
2371 * Fixed output of sorder.
2372 * `edit' can now work non-interactively. Contributed by Ron
2374 * Fixed and extended edit for sectors.
2375 * Fixed use of errno.
2376 * Minor security fix: doconfig now writes example auth entry as
2378 * Fixed reading of country name and password in client for Windows.
2379 * Replace use of some obsolete non-portable library functions by
2380 portable equivalents.
2381 * designate now warns about redesignated capital only when it
2382 succeeds in redesignating the capital.
2383 * attack could be off by one when reporting required unit mobility.
2384 * Fixed command matching. Unique prefixes were not always
2385 recognized, and junk suffixes were ignored.
2386 * Removed bestdistpath. bestpath yields the same results.
2387 * Renamed lstats to lstat for consistency and to match info page.
2388 * Fixed non-portable fd_set * arguments of select().
2389 * New `map' flag `h' to highlight own sectors. Contributed by Marc
2391 * Fixed `sabo' reporting damage to player in deity coordinates.
2392 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
2393 * Fix Windows server shutdown on reading "quit" from stdin.
2394 * Land units now fortify automatically when mobility plus growth
2395 exceeds the maximum. With code from Marc Olzheim.
2396 * Wandering che are less predictable.
2397 * Land units no longer regenerate mobility faster while it is
2399 * Fixed emp_client -k.
2400 * No longer allow pirates to ferret out where a ship was built.
2401 * Fixed map commands to reject bmap flags `t' and `r' instead of
2403 * Fixed lmine shell resupply.
2404 * News no longer call all sub-launched missiles nuclear.
2405 * Incoming missiles are now reported with coordinates.
2406 * Removed some code that served no purpose except crashing on
2408 * Fixed Mac OSX and AIX build problems.
2409 * Don't resolve player IP addresses for now, because it can crash
2410 with certain versions of GNU libc.
2411 * Fixed recording of lost nukes.
2413 Changes to Empire 4.2.12 - Mon Aug 18 16:54:21 MDT 2003
2414 * Corrected contact information for Wolfpack.
2415 * Sector isn't abandoned until move or explore is complete.
2416 * Fixed multiple cases where return value of getstarg() was
2417 used without being checked which crashed the server.
2418 * Used stdarg.h instead of varargs.h.
2419 * Call only_subs and save result before mission frees attacker
2420 list. Call with free list could cause server crash.
2421 * Fixed spy sat map for units on opposite side of world wrap.
2422 * Don't sleep in main thread when called from signal handler.
2423 * Fixed error checking in pthreads.
2424 * Properly detach pthreads.
2425 * Pass unlocked mutex to pthread_mutex_unlock.
2426 * Cope with interrupted sleep in pthread empth_sleep to prevent
2428 * Added server configurable update window.
2429 * Initialized variables passed to setsockopt in accept.c.
2430 * Fixed bug where sharing bmap with uncontacted country crashes
2433 Changes to Empire 4.2.11 - Sun Sep 1 09:54:59 MDT 2002
2434 * Added compile option for the Mac OSX architecture.
2435 * Fixed bug in cargo where unit array was indexed by shp_maxno
2436 instead of lnd_maxno.
2437 * Fixed bug in reject where aborting the command crashes the
2439 * Can't buy land units into enemy headquarters.
2440 * Added sabotage command and commando unit.
2441 * Spies moving by themselves will not trigger interdiction.
2442 * Fixed error in map distance calculation that caused errant
2444 * Ships going under -127 mobility will be set to -127 mob and
2445 not roll over to positive mobility.
2446 * Corrected plane cost in info Maintenance.
2447 * Changed error message for loans rejected for being too big.
2448 * Land units will take casualty damage proportional to their
2449 ability to carry mil.
2450 * Fixed bug where "route i *" crashes server.
2451 * Cannot upgrade planes in orbit.
2452 * Fixed bug in declare with deity aborting command at last
2453 prompt crashes the server.
2454 * Coastwatch notify works with NO_FORT_FIRE option.
2455 * Thread that kills idle connection will charge player for
2456 minutes the player was logged on.
2457 * Removed separate sendeof at end of execute from emp_client
2458 that logged players off on certain platforms.

2460 wouldn't be kicked off during long flashes or writing telegrams.
2461 * LOSE_CONTACT will work as advertised.
2462 * Allied units marching through 0 mobility conquered sectors
2463 are charged at least LND_MINMOBCOST.
2465 Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001
2466 * Assault can reinforce own sector when SLOW_WAR is enabled.
2467 * emp_client no longer converts lines into tags but still verifies executes,
2468 pipes, and file redirect match players input.
2469 * Added pboard command to capture enemy planes in your territory.
2470 * Declaring war when at Sitzkrieg won't return relations to Mobilizing.
2471 * Declaring war won't charge money if you're already Mobilizing.

2473 * "show nuke build" displays the proper avail.
2474 * retreating land units will only retreat to sectors owned by the player
2476 * added hard cap of "250 + easy" to limit_level.
2477 * education p.e. calculation divides edu constant by etu per update.
2478 * Added patch for Linux for the PowerPC.
2480 Changes to Empire 4.2.9 - Sun Jan 7 15:49:13 PST 2001

2488 * Corrected formula for likelihood of plague in info Plague.
2489 * Fixed files to correctly size map and bmap files from econfig file.

2492 Changes to Empire 4.2.8 - Mon Oct 9 17:35:35 MDT 2000
2493 * Fixed range in radar.t and Sector-types.t. Maximum range at infinite
2495 * Changed so that player can't drop civilians into occupied sectors.
2496 * Fixed bug that crashes update if etus/update is less than 8.
2497 * Fixed sometimes not reporting overflights
2498 * Fixing flak for units/ships to be in all sectors as they should be
2499 * Updated order of firing flak in Flak.t.
2500 * Fixed 80% efficient planes on ships must be maintained.
2501 * Fixed initial MOB_ACCESS check thread sleep time was set by an uninitialized
2503 * Removed "TEMPORARILY DISABLED" message from mission command for escort
2504 missions. Escort missions have been re-enabled since 4.0.15.
2505 * Using sonar from the navigate command will print the sonar map.
2506 * Eliminated annoying error messages when using navigate with conditionals.
2507 * Fixed Technology.t to correctly add 1 before taking the logarithm.
2508 * Fixed bug that allowed players to steal opponents maps.
2509 * Put time limit for bidding on market and trade in econfig file.

2512 * Added logging of cases where write extends data file by more than one id.
2513 * Option MARKET is turned off by default.
2515 Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
2516 * Added new NF_SACKED flag to indicate when a country has had it's
2517 capital sacked. This flag is only cleared when the country actively
2518 redesignates it's capital using the "capital" command, and changed
2519 capital.t to reflect this (no more re-sacking after an update if the
2520 country doesn't reset and repeating until they are out of cash.)
2521 * Added land unit to edit command for planes.
2522 * Added nuketype to edit command for planes.
2523 * Changed so that if the leader of a group of units is a train, the
2524 railways are used for bestpath instead of roadways.
2525 * Changed mission command to also print reaction radius of reserve
2526 missions when set for land units.
2527 * Changed Flak.t to reflect guns having to be loaded onto a land unit
2529 * Changed so that visitor countries cannot change their name or password.
2530 * Changed so that you cannot upgrade deity planes, ships or units.
2531 * Changed so that you know where missions are flown from.
2532 * Changed so that the airport owner you fly a mission from is informed.
2533 * Changed so that preperations for takeoff are reported to the owner of
2534 the sector, ship or unit a plane is taking off from if it is not owned
2535 by the owner of the plane.
2536 * Changed so that when a sector reverts during a guerrilla revolt, the
2537 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
2538 you would always get at least an updates worth of mobility. With
2539 MOB_ACCESS, sectors that reverted during the update were useless, since you
2540 got no mobility for a long time. This fixes that problem, and makes che
2541 more useful as well.
2542 * Changed so that air defense missions don't always send up every plane in the
2543 area, but instead always send up at most two times the number of incoming
2544 planes (for each interdicting country.) This helps to stop 1 plane from
2545 stripping the mobility from 25 air defense planes all at once, but doesn't
2546 limit it to n+1 as there is for regular interception.
2547 * Clarified deity reversion of sectors in Sector-ownership.t
2548 * Clarified production efficiency and added pointer to "show sector cap"
2550 * Clarified nuketype selector for planes in Selector.t
2551 * Clarified that fortifying units does not affect mission status in info
2552 pages for mission and fortify.
2553 * Clarified fuel syntax upon error in fuel command in empmod.c.
2554 * Cleaned up comments causing minor complaints in some builds.
2555 * Fixed bug in loans where you could collect on proposed loans.
2556 * Fixed production command to be more accurate (though it *still* has some
2557 rounding errors, it's better.)
2558 * Fixed potential memory leak in air defense missions.
2559 * Fixed bug where you couldn't pinbomb some commodities if other commodities
2560 didn't already exist in the sector.
2561 * Fixed bug where you couldn't build 0 crew planes without military in the
2562 sector. (This is different from needing at least 1 military to build all
2563 planes that need a crew which introduced another related bug earlier.)
2564 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
2565 messages to be displayed for deity owned planes.
2566 * Fixed bug where land units on ships in a sector taken over were blown
2568 * Fixed bug where planes on ships in a sector taken over were blown up
2570 * Fixed bug in sdump printing origx and origy in deity coordinates.
2571 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
2573 * Fixed bug in launch showing wrong satellite target (showed asat instead
2574 of the target satellite.)
2575 * Fixed bug where you could gain information not normally available using
2576 the "fire" command to determine sector type information.
2577 * Fixed bug in market/trade creating extra money when loans are taken out.
2578 * Fixed problem with land units not being reported sunk after being sunk
2579 on a ship that was nuked or wastelanded in a sector.
2580 * Fixed problem with Spies.t using "llook" instead of "llookout".
2581 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
2582 on some Linux boxes.
2583 * Fixed problem with plague infection being way too high in cities when
2584 the BIG_CITY option is enabled.
2585 * Fixed bug in edit command getting confused with arguments.
2586 * Fixed bug in ask_move_in_off asking you to move in a negative number of
2587 troops (hey, it could happen. :) )
2588 * Fixed bug in add command not keeping flags or relations initially correct.
2589 * Fixed bug in torpedo command sometimes telling victim about torpedo
2590 sightings even when way out of range.
2591 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
2592 as not formatting them properly when reporting them.
2593 * Fixed bug in satellite with noisy transmission causing a potential
2594 crash of the server with non-100% efficient satellites.
2595 * Fixed potential crashing of the server during satellite display when not
2596 calculating distances to ships and units correctly.
2597 * Fixed bug where planes in non-allied sectors, ships and units could be
2599 * Fixed bug where planes on the trading block could be used on missions.
2600 * Fixed bug where planes and units that get traded don't have mobility set
2601 correctly when using MOB_ACCESS option.
2602 * Fixed bug which made security units virtually useless.
2603 * Fixed access times and mobility not being set right when building planes,
2604 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
2605 * Fixed minor formatting problem with launch of satellites.
2606 * Fixed minor formatting problem with planes with greater than 999 tech.
2607 * Fixed minor formatting problem with ships with greater than 999 tech.
2608 * Fixed problem with "llook" showing up in TOP info file.
2609 * Fixed problem with lwp Makefile choking on NT builds with clean target.
2610 * General cleanup of potentially ambiguous statements.
2612 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
2613 * Added "TECH_POP" as an option where technology costs more to make
2614 as your population grows past 50K civilians. It is disabled by
2616 * Changed "produce" command to accurately print what the true p.e. is.
2617 * Changed "update" command to display if mobility updating is enabled for
2619 * Fixed bug where toggling off the coastwatch flag also turned off
2620 forts firing on hostile ships coming into range.
2621 * Fixed bug where assaulting your own land would violate any treaties
2622 you have where assaults are a violation.
2623 * Fixed bug where all planes (even those without need for a crew, such
2624 as missiles) needed at least 1 military to build.
2625 * Fixed bug where when a ship sinks during the update due to lack of maint,
2626 land units and planes on it were left stranded.
2627 * Fixed bug where when a land unit dies during the update due to lack of
2628 maint, land units and planes on it were left stranded on it.
2629 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
2631 * Fixed bug in "show sector capabilities" not showing products correctly.
2632 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
2634 * Fixed bug in sectors that don't revolt not showing up as lost items.
2635 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
2636 * Fixed bug where MOB_ACCESS was not updating the mobility just before
2638 * Fixed bug in the way treaties are examined and sometimes produce
2640 * Fixed edit to allow creating negative mobility for sectors.
2641 * Fixed setsector to allow creating negative mobility for sectors.
2642 * Fixed bug where when writing out the value of a sector that had
2643 negative mobility and was damaged in combat, mobility was being
2645 * Fixed Taxes.t info page to reflect that captured civvies only pay
2647 * Fixed Technology.t info page to reflect TECH_POP option.
2648 * Fixed navigate.t info page to reflect that only ships in the fleet
2649 in the same sector that are fired upon have damage divided up.
2650 * Made techlists toggle on by default (so things are shown in order of
2651 technological advances.)
2653 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
2654 * Added optimization to increasing mobility to check if an object is
2655 already at max mob, just return since it can't be increased.
2656 * Added "-ltermcap" for client libs for hp build (it was already in
2658 * Added clearing of telegram flags after the update so that the next
2659 telegram is flagged as new and not part of the update.
2660 * Fixed Update-sequence.t to reflect MOB_ACCESS.
2661 * Fixed bug where fortification amount was not being limited to
2662 maximum mobility for land units (land_mob_max).
2663 * Fixed bug where land unit fortification strength was being calculated
2664 by using 127 instead of land_mob_max.
2665 * Fixed bug where scrapping land units was creating military.
2666 * Fixed description of sect_mob_neg_factor in econfig file.
2667 * Increased speed of PT boats.
2669 Changes to Empire 4.2.4 - Tue Feb 2 05:47:44 PST 1999
2670 * Added check to make military values match up correctly for land
2672 * Fixed bug in doconfig not putting ipglob.c in the right place.
2673 * Fixed bug where attacking deity sectors will violate a treaty.
2674 * Fixed newspaper.t information file.
2675 * Fixed potential bug in fixing up timestamp information when restarting a
2676 game with MOB_ACCESS turned on.
2677 * Fixed bug in explore command not setting mobility to correct
2678 value when MOB_ACCESS was enabled.
2679 * Fixed bug in enlist setting mobility incorrectly sometimes.
2680 * Added doc/backup file for deities which recommends how backups and
2681 restores of the data directory should be done.
2683 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
2684 * Added linux-pthreads target and build for using pthreads under Linux.
2685 * Added NO_FORT_FIRE option which disables the ability of forts to
2687 * Added more error checking and recovery for corrupt data files.
2688 * Changed alphapos target to alpha-pthreads for better clarity.
2689 * Changed fairland to allow 0 sector distance to other islands and
2690 continents (James Risner)
2691 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
2692 match the way ships are described (since this is how they really work.)
2693 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
2694 and "fir" as the number of guns that a land unit fires.
2695 * Cleaned up misc. build warnings.
2696 * Changed artillery damage to be 5 + d6 per gun firing from just d6
2697 per gun firing and updated Damage.t to reflect this change.
2698 * Changed artillery firing ranges to be like ships ranges - divided
2699 by two, and modified them to make more sense.
2700 * Changed artillery units to be "slightly" :) more powerful.
2701 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
2702 * Changed "artillery" unit to tech 35.
2703 * Changed so that guns are no longer required to build units, and
2704 that guns must be loaded onto artillery units for them to fire.
2705 Client developers note: the show command has not changed yet to
2706 remove the 'guns' column (since guns are no longer required) but
2707 will in a future revision (possibly 4.2.4) so "be prepared" for
2708 "show land build" to change. :)
2709 * Fixed landunitgun to handle all the damage calculations like it should.
2710 * Fixed bug sinking planes when the ship they are on sinks.
2711 * Fixed bug destroying planes when the land unit they are on is destroyed.
2712 * Fixed bug where land units could fire support without enough military.
2713 * Fixed bug in abandoning sectors by marching out a land unit where it
2714 would not let you sometimes (uninitialized variable problem.)
2715 * Fixed gets problem in files.c (James Risner)
2716 * Fixed bug in determinig operations range of a ship.
2717 * Fixed bug in building planes where you could manufacture military.
2718 * Fixed warnings in threading package(s).
2719 * Fixed fire.t to reflect new firing changes.
2720 * Fixed lstat.t to reflect new firing changes.
2721 * Fixed sstat.t to reflect the way things really work.
2722 * Fixed Ship-types.t to reflect the way things really work.
2723 * Fixed the way shutdowns work to hopefully better protect data files.
2724 * Fixed bug in attacking when sector mobility is less than 0 and it would
2725 prompt for attacking with a negative amount of military.
2726 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
2727 * Fixed bug in client when it prompts for country name it was putting
2728 an extraneous end of line on the end that needed to be stripped off.
2729 * Fixed problems running on Linux running on an Alpha machine. Thanks
2730 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
2731 on a machine to work out the bugs. (Note that the only build that
2732 works on Linux/Alpha is the linux-pthreads)
2734 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
2735 * Added some code optimizations into the update code when building paths.
2736 * Added some new cacheing for building paths to help speed up updates.
2737 * Added so that you can use "name" and "password" with the change command
2738 as well as "country" and "representative".
2739 * Added flag to power command so that if you are a deity and enter
2740 a negative number of countries you want to see, you see the power chart
2741 for that many countries without power numbers on the next line. Only
2742 useful for deities that want to see the chart un-broken up by that line.
2743 * Added new functionality to fortify command. You can now use a negative
2744 fortification value to cause the unit to be fortified and leave at
2745 least that much mobility on the unit. I.E. "fort * -67" will fortify
2746 all units and make sure the mobility of each unit doesn't go below
2747 67. If the mobility is already below that level (or equal) the unit
2749 * Added that the realm command prints "Realm #n is x:x,y:y" after
2750 you set a new realm.
2751 * Added TREATIES option and enabled it by default.
2752 * Added "no depth-charging subs" and "no new land units" treaty
2754 * Added Trannie Carter's basic client fix to use fgets instead of gets.
2755 * Changed market and command to only print the lowest priced lot of
2756 each given commodity by default. If you specify "all" it shows
2757 all lots on the market, and if you specify a specific item, it shows
2758 all lots of that item type.
2759 * Changed start command to only write out sector if it changed.
2760 * Changed stop command to only write out sector if it changed.
2761 * Changed how plane names were changed on server startup if the
2762 PLANENAMES option was enabled.
2763 * Changed move command to use standard askyn function for abandoning
2765 * Changed plane overlight sightings to take stealth into account,
2766 and if the planes managed to evade all flak and interceptors, they
2767 are not marked as "spotted" over enemy sectors.
2768 * Changed all units with the supply flag to have their marching speeds
2769 based on efficiency since that is their purpose. What this means is
2770 that supply units and trains are more effective at 100% than at 10%
2771 (just as fighting units are more effective at 100% than at 10%, but
2772 their effectiveness is determined by how well they fight, not how well
2773 they "run away, run away!" :) )
2774 * Changed so that flash toggle is on by default for POGO at setup
2776 * Changed so that when a sector is taken, all land units owned by the
2777 current owner are treated as planes are during takeovers (i.e. there
2778 is a pretty good chance they are blown up, and if not, they change owner
2779 to the attacker and are beat up pretty good.)
2780 * Fixed treaties to work again.
2781 * Fixed bug in taking over land units not using correct pointer (can
2782 cause a crash or data corruption.)
2783 * Fixed collect command to wipe deliver and distribution information
2785 * Fixed potential bug in bmap not working when destination bmap has
2787 * Fixed bug in shark command not getting right nation structure.
2788 * Fixed bug in server where empty commands (for example, all spaces
2789 or tabs) were being reported as bogus commands. They are now just
2791 * Fixed bug in scrap not dropping land units off of scrapped units carrying
2793 * Fixed bug in news where boarding of land units was reported backwards.
2794 * Fixed bug in calculating new people when growing them during an update.
2795 * Fixed missing -ltermcap in HP/UX build.
2796 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
2797 later and being reset to 0 anyway)
2798 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
2799 since that is what it really is.
2800 * Fixed retreat.t documentation to reflect the "retreat upon failed
2802 * Fixed bug where satellites were not orbiting the world during the
2804 * Fixed bug in torpedos being too smart. They knew how to jump over
2805 land! :) Now the "line_of_sight" routine is used to determine if a
2806 torpedo has a straight path to the destination. If it doesn't, the
2807 torpedo no longer jumps over land, but instead slams into it. This was
2808 an interesting bug because you could torp ships on the other side of
2809 a very skinny island as long as they were in range, even if there was
2810 no sea route possible.
2811 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
2812 units for example) but you still have to pick something to bomb. For
2813 ships it worked ok (just aborted that it couldn't find any more ships)
2814 and this was fixed for land units and planes.
2815 * Fixed server crashing bug when flying a plane and not carrying
2817 * Fixed bug in move losing commodities when it runs out of room in the
2818 destination sector. Goods are now attempted to be returned to the
2819 start sector, and apporpriate steps taken if the start sector is no
2821 * Fixed march to prompt you before you abandon a sector you own by
2822 marching out the last land unit.
2823 * Fixed check functions to only check the relevant portions of the structure
2824 and not the timestamp info that doesn't affect how the object functions.
2825 * Fixed bug in spy command that always told you if a spy unit was in a
2827 * Fixed bug in displaying of land unit missions not showing correct land
2829 * Fixed bug in wire command where new announcements that you read at
2830 the last second don't get wiped out properly.
2831 * Fixed bug where announcement file could be corrupted by very long lines.
2832 * Fixed bug where bmap was not set when player was told what kind of
2833 sector they were attacking (this was an old abusable bug that was
2834 removed long ago to fix the abuse, and it's been fixed in a non-abusable
2836 * Fixed bug where change command would warn you about monetary and
2837 BTU costs, but not prompt you to break out if you didn't want to really
2838 change your country name.
2839 * Fixed bug in sub-launched nukes that are intercepted being reported in
2840 the news incorrectly.
2841 * Fixed bug in load where you could abandon a sector and not know it by
2842 loading your last civilians or military onto a ship.
2843 * Fixed potential memory leak in autonav code.
2844 * Fixed potential bug where you could possibly determine if a sector is
2845 owned or not using one way plane missions.
2846 * Fixed Damage.t info page to properly show damages for planes and
2848 * Fixed deliver.t to include syntax for command.
2849 * Fixed country.t to include syntax for command.
2850 * Fixed bug where ships on orders were not adding radar information to
2851 the bmap during an update.
2852 * Fixed bug where ships on sail were not adding radar information to
2853 the bmap during an update.
2854 * Fixed bestownedpath code to use the bmap properly. Note this is a very
2855 important bug fix. When navigating a ship, players are no longer given
2856 free information that they would not normally know. For example, if you
2857 try sailing your ship off into uncharted areas of your bmap, the bestpath
2858 code will only use as much information as you have on-hand (i.e. your
2859 bmap) to plan out your path for you. If you have no information on an
2860 area, it just keeps forging on, until bumping into something. Of course,
2861 after the initial exploration through an area, the bmap will be set and
2862 used for all future sailings through that area. Harbors and bridges
2863 are still checked for construction worthiness if you know where they
2864 are (i.e. they are on your bmap.) (Overall, what happened before
2865 was that the bestpath code would route your ship around islands that
2866 you didn't even know were there, and you could use various commands
2867 to see how that ship was going to sail during the update and thus you
2868 gained information that you wouldn't normally know.)
2869 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
2870 and "BestAirPath" to use it properly. It is also good to note that
2871 bestownedpath is used to determine paths for ships and for planes,
2872 and that best_path (which uses the A* algorithm) is used for all land
2873 based paths, and that the two are never interchanged.
2874 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
2875 and RECON was never used before.)
2876 * Removed extraneous "resnoise" and "resbenefit" functions and combined
2877 the two for setresource and setsector commands.
2879 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
2880 * Fixed problem with global/plane.c not defining last structure element
2881 properly, and thus causing crashes when accessing certain plane
2882 routines. This happened during the move to make the PLANENAMES option
2883 run-time configurable.
2885 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
2886 * Bumped rev to 4.2.0 since this is a major release (the server is now
2887 run-time configurable for just about everything and is released under
2889 * Put in official licensing information.
2890 * Re-arranged and commented the econfig (Empire Configuration) file. The
2891 auto-generated "data/econfig" file is now pumped out chock full of
2892 comments (which may or may not be useful.) Since the server is
2893 pretty much fully run-time configurable (MAXNOC is not, but it gets
2894 a default of 99 anyway) deities will probably be spending more time
2896 * Added server support for building under NT, including mods from
2897 Doug Hay and Steve McClure to get the server building and running
2898 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
2900 * Added Doug Hay's ntthread.c implementation for NT threading.
2901 * Added max pop column to "show sector stats" output.
2902 * Added lboard command for boarding land units from sectors. Only raw
2903 mil can board land units, and only mil and land units aboard the unit
2904 being boarded fight back.
2905 * Added GODNEWS option. When enabled, the deity giving people stuff
2906 is shown in the news.
2907 * Added bridge tower sector ('@')
2908 * Added BRIDGETOWERS option. When enabled you can build bridge towers
2909 from a bridge span. You can then build bridge spans from the tower.
2910 If the tower is destroyed ( <20% eff) bridges connected fall unless
2911 supported on the other side. You can only build bridge towers in open
2912 water not adjacent to land and other towers. Expensive.
2913 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
2914 it is deity creatable only (can't redesignate unless you wasteland it
2916 * Changed "info all" to no longer use printdir, instead it just uses the "all"
2917 info page which contains this information.
2918 * Changed so you can now load up to 2 spy units onto non-land unit carrying
2919 submarines if the LANDSPIES option is enabled. Useful for sneaking up
2920 to shore and spying on your neighbors.
2921 * Changed so spies unloaded from ships are not given as gifts, they are just
2923 * Changed build command to handle building towers ("build t")
2924 * Changed show command to show tower stats ("show t b")
2925 * Changed reject so you can now reject things from any country except
2926 deity countries (this now includes sanctuary countries and visitor
2927 countries you don't want to deal with)
2928 * Changed ndump to dump nuclear stockpile ID as well.
2929 * Changed flash so that if someone allied to you is either not logged on or
2930 not accepting flashes, you are notified. This is info you could gain
2931 otherwise since you can see other countries that are allied to you via
2933 * Fixed bug in news command when HIDDEN mods are enabled.
2934 * Fixed distribute command to only write out to the database if we
2935 actually changed the sector (i.e. if we really moved the dist
2936 center, we write. Otherwise, it makes no point.)
2937 * Fixed threshold command to only write out to the database if
2938 we actually changed the sector (i.e. if we really changed the
2939 threshold, we write. Otherwise, it makes no point.)
2940 * Fixed - population growth and truncation in "Update-sequence.t" info
2942 * Fixed the way fortify takes mobility away from a land unit if
2943 engineers are present.
2944 * Fixed bug in buying commodities at the last minute not resetting the
2945 time correctly in all situations.
2946 * Fixed bug in building nukes where it would always ask if you tried
2947 building more than one at a time.
2948 * Fixed bug where if you put (either by building or by transporting)
2949 more than 127 of one type of nuke in a sector, they all got lost. A
2950 negative wrapover sort of thing.
2951 * Fixed ndump to print # of stockpiles dumped.
2952 * Fixed ndump.t to reflect changes
2953 * Fixed bug in build command that didn't account for EOL characters.
2954 * Fixed bug where you could use planes to drop conquered populace
2955 * Fixed bug in distribute command in how it checked for current distribution
2957 * Fixed pr_flash and pr_inform to no longer send messages if the player
2958 is still in the process of logging in (i.e. not in the PLAYING state)
2959 * Fixed report command output for deities.
2960 * Fixed bug in nuclear damage either taking out submarines when it
2961 shouldn't, or not taking them out when it should.
2962 * Fixed bug in loading units that are carrying units onto other units
2963 (note that it doesn't happen since only HEAVY units can carry other
2964 units and that check works, but that might change some day, and we
2965 don't want units carrying units to be carried by other units, etc. :) )
2966 * Fixed info pages to reflect new sector types.
2967 * Fixed info pages to reflect new spy unit capabilities.
2968 * Fixed show commands to only show trade ships if the TRADESHIPS option
2970 * Fixed build command to only allow building of trade ships if the
2971 TRADESHIPS options is enabled.
2972 * Fixed up some definitions located in many places used for checking
2973 sectors for navigation rights.

2978 * Made SAIL option run time configurable.
2979 * Made MOB_ACCESS option run time configurable.
2980 * Made FALLOUT option run time configurable.
2981 * Made SLOW_WAR option run time configurable.
2982 * Made SNEAK_ATTACK option run time configurable.
2983 * Made WORLD_X and WORLD_Y run time configurable.
2984 * Made MARKET option run time configurable.
2985 * Made LOANS option run time configurable.
2986 * Made BIG_CITY option run time configurable.
2987 * Made TRADESHIPS option run time configurable.
2988 * Made SHIPNAMES option run time configurable.
2989 * Made DEMANDUPDATE option run time configurable.
2990 * Made UPDATESCHED option run time configurable.
2991 * Made LANDSPIES option run time configurable.

2993 * Made PLANENAMES option run time configurable.
2994 * Removed SMALL_SERVER stuff (unused baggage)
2995 * Removed trading post sector ('v')

2999 defense planes and take no damage (i.e. they got to fight twice,
3001 * Fixed bug in freeing memory after performing missions that could crash
3002 the server (it mainly happened after an interdiction mission using
3003 planes and escorts, where some escorts came from airports that didn't have
3004 bombers going up. Freeing the leftover escorts was crashing the server.)
3005 * Fixed bug where you could load non-existant units if you were allied
3007 * Fixed bug where you could pin-bomb a plane with itself.
3008 * Fixed bug where satellites over a bridge may get killed if the bridge
3010 * Fixed bug where land units on a ship in the same sector as a bridge

3024 to due to a perceived change in item status.
3025 * Fixed bug in mfir.c where a bogus input to a target could crash
3027 * Fixed bug that after you read telegrams new telegrams may not send
3028 an inform message (the old telegram flags were not cleared.)
3029 * Fixed bug where fort support distance calculations are calculated
3030 twice instead of just once. This bug caused a lower percentage
3031 of support fire than designed.
3032 * Fixed bomb.t to reflect land unit changes.
3033 * Put in some integrity checking for planes returing from bombing runs.
3034 * Added ability to edit land unit that a land unit is loaded on in
3036 * Consolidated bridgefall code into "knockdown" function (this code

3044 * Updated Education.t
3045 * Modified (increased) chances of hitting mines slightly.
3046 * Removed unused variables from shp_check_mines.

3052 that exist in the sector you are spying from.
3053 * Modified naval planes and anti-sub planes.
3054 * Changed so that missiles and bombs that miss their targets cause
3055 collateral damage in the target sector (they have to land somewhere!)
3056 * Changed llook so that non-spy units are required to have at least 1
3057 military personnel on board to see anything.
3058 * Fixed "llookout.t" to reflect change for military requirement.
3061 * Added "lmine" flag for deities to see what sectors have mines in them

3067 * Firing land units are required to have at least on military loaded to

3073 * Updated tax information in Innards.t and Update-sequence.t

3115 Larsen. They are described with other changes below.
3116 * Fixed bugs in the following commands that allowed two cooperating
3117 countries to create infinite numbers of any commodity and/or cash

3339 * Fixed "show plane cap" to move the last column over 1 more where it should
3341 * Fixed timestamps to be updated for units/planes on ships/units that move,
3342 since those units/planes move too.
3344 Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
3345 * Fixed bug in nstr_exec that was wiping out the previous conditional.
3346 This was major because it affected timestamp values which are more
3348 * Fixed bug in sdump.c for typo in reporting the trade ships origin.
3350 Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
3351 * Fixed bug in aircombat.c when calculating the air combat odds. Negative
3352 numbers were screwing things up good...
3353 * Fort sector's coordinates are no longer printed when auto-firing at
3355 * Subs can now surface and fire deck guns (again) They can also be
3356 hit by return fire when doing so.
3357 * Fixed bug in setting of plane attack and defensive values so that
3358 negative numbers don't keep going further negative.
3359 * Fixed incorrect military control calculation in the sell command.
3360 * Trading posts are no longer required to sell goods from. You can sell
3361 from harbors and warehouses now too.
3362 * Spy now prints out the owner of land units you see when spying. Before
3363 this was assumed to be sector owner, which is no longer true.
3364 * Loading land units now prints out what was loaded onto each unit,
3365 just as loading ships do.
3366 * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output.
3367 * Added "GO_RENEW" option. This option means that gold and oil resources
3369 * Added "lost_items_timeout" config variable, and set the default to
3370 48 hours. This determines how long lost items stay in the lost items
3372 * Fixed land unit names to be more consistent.
3373 * Fixed mission.t info page.
3374 * Fixed bug in that if mission_mob_cost was set to 0, even negative
3375 mob units should be able to be put on missions.
3376 * Removed restriction on things needing to be at least 60% to be put
3377 on a mission. Note that while you can put them on missions at < 60%
3378 now, when trying to do the mission, it still checks the eff. This
3379 is to help in automatic setup (build, put on mission, forget) instead
3380 of having to come back repeatedly.
3381 * Spies caught in Neutral or Friendly countries cause the Neutral or
3382 Friendly country to go Hostile towards the owner of the spy.
3383 * Tweaked ammunition numbers for artillery units.
3384 * No more automatic declarations of War should be made. You will go
3385 hostile, but since going to war doesn't increase your countries
3386 defenses, and is purely political, it is left to the player to go
3388 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
3389 * Fixed bug in "lmine" that was crashing the server if the land unit was
3391 * Fixed buy so that if you specify a product, you can only bid on that
3393 * Added "lost.t" info page.
3394 * Added "lost items" database (EF_LOST)
3395 * Fixed bug where you could move in allied forces after an attack if they
3396 bordered the victim area.
3397 * Fixed nstr_comp to deal with values > 16 bits coming in from
3398 client for comparisons.
3399 * Changed last minute market/trade timers to increment 5 minutes. 2 minutes
3401 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
3402 * Commented out the logging of the market checking in server/marketup.c,
3403 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
3404 pretty much useless data that made parsing the server.log file more
3405 more difficult than it needed to be.
3406 * Fixed crashing bug in ldump.
3407 * sdump, ldump, ndump, pdump and dump now print out the current
3408 timestamp on the "DUMP XXX" line.
3409 * Fixed denial of service bug in lib/player/accept.c in
3410 player_find_other function.
3411 * Fixed bug in shark reporting incorrect buyer of the loan.
3412 * Fixed bug in sdump.c (case 0 should have been case 10)
3413 * ldump and sdump now always print the fuel column if asked for,
3414 even if opt_FUEL is turned off. In the case that it is turned
3415 off, the fuel is listed as 0.
3416 * Added "timestamp" field, which is updated every time an item is
3418 * Fixed up the Clients.t info page.
3419 * sdump now prints trade ship building origin.
3420 * sdump now always prints name even if SHIPNAMES isn't defined. If
3421 it is not defined, then the name is empty.
3422 * Added "timestamp" to info/Concepts/Selector.t
3423 * Added some more relevant info to info/Server/Empire4.t
3424 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
3425 is no longer torn down when a sector is re-designated.
3426 * Fixed sell.t to more accurately reflect the time-delay market.
3427 * Fixed read.t and wire.t to reference accept and reject.
3428 * Fixed reject.t not referencing accept command.
3429 * Fixed collect.t to more accurately reflect what goes on when collecting
3431 * Fixed financial.t to reflect defaulted loans.
3432 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
3434 * Fixed "census.t" (had incorrect reference to "info syntax" instead
3437 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
3438 * Increased damage from depthcharges because on increased damage from
3439 torpedos. Sub frange decreased to be more balanced with destroyer frange.
3440 * Intelligence reports (spy) on units will now report the estimated number
3442 * Fixed equation for ship visibility so it will drop as tech increases.
3443 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
3444 land units, planes, and nukes.
3445 * If fields are provided, dump will only supply those fields requested.
3446 * Decreased speed of subs.
3447 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
3448 required for infrastructure improvements.
3449 * Units that lose an assault or a boarding attempt from a ship will no
3450 longer swim back to the ship they came from.
3451 * Units that take extra casualties will no longer lose all their mil at
3453 * Infrastucture is retained when redesignating a sector.
3454 * Dieing spies will no longer crash the server.
3455 * Units, planes, and ships must have mobility to perform missions.
3456 * Units on ship being scrapped are transferred to harbor.
3457 * Food is no longer autoloaded onto units when they are built.
3458 * Fixed show plane stat to show correct range.
3459 * Infantries now take damage at same rate as casualties.
3460 * Fixed bug with hap_fact. Having more happiness now helps with fighting
3462 * Fixed anti to write back target country so che will continue to fight
3464 * Fixed llookout to show correct estimate on number of mil on unit.
3465 * Added buildable architecture "hp". This type will build the server on
3466 a HP/UX machine using the standard compiler instead of gcc.
3468 Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
3469 * Fixed bug in update/distribute.c where pathcost was not being called with
3470 the MOB_ROAD argument (and thus distribution costs could be GREATLY
3471 affected.) - Thanks Ice!
3473 Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996
3474 * Fixed Solaris port using gcc.
3475 * Fixed doconfig.c to create directories with right modes.
3476 * Fixed install macros in makefiles to move binaries to the right
3479 Changes to Empire 4.0.3 - Wed Dec 4 22:46:53 EST 1996
3481 * Fixed doconfig.c (put exit(0) at the end of main.)
3482 * Fixed improve.c (moved the prompt[] string outside the fcn.)
3484 Changes to Empire 4.0.2 - Mon Oct 14 12:26:40 EDT 1996
3485 * Put in LND_MINMOBCOST in land.h
3486 * Put in change in lnd_mobcost in lndsub.c
3487 * Put in new nuke costs in nuke.c
3488 * Put in fix so that total work can only be done by the max pop. No more extra
3489 civvies tossed in will do it anymore in human.c.
3490 * Put in fix for src/util/Makefile - beefed it up.
3491 * Put in fix to show where your ship is when it gets shelled in mfir.c.
3492 * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in
3494 * Fixed Update-sequence.t.
3495 * Put in fix for mobcost bonus for 0% highways.
3498 * Spruced up torpedo damage somewhat. :) :)
3499 * Fixed "assault bmap bug" in attsub.c
3500 * Fixed Produce.t (bars cost)
3501 * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
3505 * Fixed "offer" and "consider" not being legal commands in player/empmod.c
3508 * Fixed lstat.c, pstat.c and sstat.c
3509 * Fixed cutoff command in cuto.c
3510 * Fixed attack value in attack_val in lndsub.c
3511 * Fixed lload in commands/load.c
3512 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
3513 always fight until dead or retreating. 0 makes them get stuck.
3514 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
3515 else for that matter.)
3516 * Fixed llook in commands/look.c
3517 * Fixed che bug in subs/nstr.c
3518 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
3519 of people would starve.)
3520 * Fixed update/human.c - feed_people rounding problems (I hope.)
3521 * Fixed morale problem in update/land.c
3522 * Fixed count_bodies in attsub.c
3523 * Fixed lnd_mobcost.
3524 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
3525 * Fixed interest rate in commands/offe.c
3526 * Fixed bug in buy.c.
3527 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
3528 infrastructure. When off, the defensive infrastructure is the same
3529 as the sector efficiency, and you can't improve it. This is OFF by
3533 * Land units are now built with a default reaction radius of 0.
3534 * Changed name of lt artilleries to "lat" from "lart" so you can now build
3536 * Lowered the speed and firing range of pt boats.
3537 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
3539 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
3540 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
3541 1.5 * ETU_RATE for ships.)
3542 * Conquered civvies only pay 1/4 taxes.
3543 * Railways don't get torn down when you rebuild sectors anymore (but roads
3544 and defenses do (if enabled.)
3546 Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
3547 * Added "extern double tradetax" to check_trade in trad.c
3548 * Improved description of data directory in build.conf
3549 * Fixed bug in attacking land units that retreat so they now get
3550 charged mobility for attacking.
3551 * Fixed dump to report road, rail and defense of a sector at the end.
3552 * Fixed doconfig bug in not checking the right directory to see if the
3553 "data" directory existed or not before trying to create it.
3554 * "change" now works for sanctuary countries.
3555 * Fixed the description of "sinfrastructure".
3556 * Added more info to "Infrastructure".
3557 * Units/planes are no longer reduced to 75% when bought from the trading
3559 * Supply units were slowed down to the speed of infantry units.
3560 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
3561 * Bars interest is up to $250 per 1K again.
3562 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
3563 * Fixed various info pages.
3564 * Fixed bug in people not getting truncated when broke (this was thought
3565 to be fixed, but wasn't. Now it is, dammit!)
3566 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
3567 * Market/trade taxes and trade ship payoff figures were added to version.
3568 * "cede" has been removed as a default command.
3569 * Makefile rule was fixed for depend build.
3570 * Fixed bug in mapdist not taking world edges into account nicely enough.
3571 * Added a "scuttle" order for autoscuttling trade ships. Makes using them
3572 easier. Cleaned up scuttle code while in there.
3573 * Fixed bug with scuttling a ship with units on it not scuttling the units
3576 Changes to Empire 4.0.0 - Wed Aug 21 1996
3577 * Initial Wolfpack release - Long live the Wolfpack!!!!
3578 * Cleaned up the build environment. Now all that is needed is to edit the
3579 build.conf file, answer the questions there and type "make <arch>" to
3580 build for a specific architecture. Thus, no more reliance on gnumake
3581 or special shell scripts.
3582 * We are now shipping the pre-built info pages with the server for those who
3583 Don't want to build them. You can also still just type "make" and have
3584 the info pages build, but it doesn't completely work (i.e. rebuild new
3585 Subjects) if you don't have perl5 installed.
3586 * Put in the "help" command that does the same thing as "info".
3587 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
3588 wish to support it. 2) We envision a better scheme for doing similar
3589 things will come along.
3590 * Put in MOB_ACCESS - This allows real-time updating of mobility.
3591 * Put in MARKET - This is the time-based market (yes, still teleports,
3592 but it's not as bad as it was.)
3593 * Lots of the documenation has been updated, but there is more to do.
3594 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
3595 enabled, you don't need any of that type of material to build things.
3596 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
3597 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
3598 any materials to build a bridge.
3599 * There is no mobility cost for assigning missions. But, there is also
3600 no longer any benefit for being on a mission either.
3601 * Damage is the same for all commodities (people too.) This means you
3602 can deity shell/bomb sectors again.
3603 * Units are now dependant on tech. What this means is that their statistics
3604 now increase with tech. In addition, there is only 1 type of each basic
3605 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
3606 This reflects the idea that as you learn more, you learn how to not only
3607 build better units, but you learn to build units better. :) This also
3608 opens the door for a "lupgrade" command along the same lines as the
3609 "upgrade" command for ships.
3610 * Units now have a minimum mob cost for attacking a sector. Marching
3611 mob costs have not changed.
3612 * Starting units have been removed. This means that at the beginning, people
3613 may live a little longer since their neighbor can't come visiting quite
3615 * Shells are no longer required to build units.
3616 * Mil are no longer required to build units.
3617 * Mil are no longer an intrinsic part of a unit. They are now a loadable
3618 commodity. The way a unit's defense/att bonuses work now are
3619 attack = (att * mil * eff)
3620 defense = (def * mil * eff)
3621 In addition, when a unit takes damage, both the eff and the mil go
3622 down. You can quickly toss in new hacks, but you need to wait to repair
3623 the unit at the update. Thus, you can now look at unit's efficiency
3625 * You need at least 1 mil on a unit to march it (spies are the exception.)
3626 * Units always react if in range and they have the mobility, no matter
3627 what their efficency.
3628 * Units may now march anywhere - in your own sectors, deity owned sectors
3629 or allied sectors, with 1 exception, spies. Also, your units can get
3630 trapped if your ally declares non-alliance with you while your units
3631 are still in his country.)
3632 * Units always march at their speed, efficiency doesn't matter.
3633 * LANDSPIES was added - This creates land unit based spies. Spies may march
3634 anywhere, with a chance of getting caught (except in allied territory.)
3635 See "info Spies" for more info on them.
3636 * Planes may now be based out of allied airports. Landing planes on
3637 ships/sectors you do not own no longer changes thier owner. You can only
3638 land on owned/allied sectors/ships, and you may only
3639 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
3640 you are allied with goes hostile at you, your planes are now stuck there.
3641 Note that if you are using an allied airport, their commodities get
3642 sucked up, not yours (obviously.)
3643 * Planes are now tech-based. Their statistics increase as their tech
3644 increases. Deleted extraneous planes.
3645 * There is a new toggle, "techlists", which allows you to see what you
3646 can build/stats/capabilities sorted by tech instead of groupings.
3647 * Ships are now tech-based. Their statistics increase as their tech
3648 increases. Deleted extraneous ships.
3649 * Che can now be lessened by making happiness. If you have more happiness
3650 than your conquered populace, they don't fight as hard or recruit as
3651 much. If you have less than them, they fight harder and recruit more.
3652 It's not much though - it ranges from 2.0 in your favor to only 0.8
3653 against you (whereas it was always 1.0 before.) So, it definitely
3654 favors the attackers to make lots of happy now.
3655 * Bridgeheads can only be built on coasts.
3656 * Players command was fixed so you only see allies, and don't get
3657 approx #'s of players anymore.
3658 * POSIX threads support has been added.
3659 * The attack bmap bug has been fixed.
3660 * BTUs regenerate 3 times faster now.
3661 * GRAB_THINGS is off by default.
3662 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
3663 as a default (you couldn't make wasteland before with FALLOUT, now
3665 * You can now deliver military and civilians.
3666 * Added SHIP_DECAY option - off by default (turns off ships decaying out
3667 at sea if not enough mil.)
3668 * The reverting owner bug has been fixed in territory, thresh, dist
3669 and deliver. There are probably more, and when found, will be fixed.
3670 * The "sectors don't starve when stopped or broke" bug has been fixed.
3671 * The "people never get truncated" bug has been fixed.
3672 * Added infrastructure to sectors. What this means is that a sector
3673 can now have it's mobility improved by building both roads and
3674 railways. It also means that a sectors defense is now based on the
3675 defensive infrastructure you build into the sector (no more intrinsic
3676 better defenses based on the sector, you determine which sectors are
3677 defended heavily, and which aren't.)
3678 * The defensive value of a sector no longer relies on the efficiency of
3679 the sector. Instead, it relies on the defensive efficiency of the sector.
3680 Thus, the "production" and "defensive" aspects of sectors have been
3682 * "show sect stats" now shows the maximum defensive value for sectors.
3683 * Changed sector structure to take floats for off/def values so we can use
3684 a base of 1 instead of 2.
3685 * Added "improve" and "sinfrastructure" to support the infrastructure
3687 * Added L_TRAIN units which can only travel along railways. Very fast on
3688 efficient railways, slow on non-efficient ones.
3689 * Added the ability for units to carry other units.
3690 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
3691 * Forts only cost $500 to build and 100 hcms now (since they don't get any
3692 better defenses automagically.)
3693 * Modified "show sect build" to show the costs for building up the
3694 infrastructure of a sector.
3695 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
3696 spyplanes too) to show the new infrastructure stuff, rounded of course.
3697 * Added Drake's info->html scripts, with some modifications, so you can
3698 now type "make html" and have your info pages built as html files too.
3699 This adds a new directory, "info.html", to the build tree.
3700 * Modified upgrade so that planes and land units may now be upgraded.
3701 * Added pstat command to list the statistics of your planes.
3702 * Added lstat command to list the statistics of your land units.
3703 * Added sstat command to list the statistics of your ships.
3704 * Added nmap command to show a map of your sectors after their new
3705 designations have taken place.
