1 Changes to Empire 4.3.20 - Fri Feb 20 18:14:20 UTC 2009
2 * Option LOANS is now disabled by default.
3 * Option RAILWAYS is now enabled by default.
4 * Many fixes to automatic supply:
5 - Planes flying interception or support missions, abms intercepting
6 ballistic missiles, and the launch command for missiles and
7 anti-sats could all supply more shells than necessary, lose
8 shells, or conjure them up.
9 - Ships shooting down marine missiles could supply more shells than
10 necessary, or lose shells.
11 - Supply ships could conjure up shells when firing guns using
12 multiple shells, or launching torpedoes, or dropping depth
13 charges, or shooting down marine missiles. No supply ships
14 capable of doing that exist in the stock game.
15 - Supply engineers could conjure up shells when laying mines. They
16 don't exist in the stock game.
17 - load, lload and supply could supply land units with enough food
18 from the sector containing them to starve the sector.
19 - Sectors were charged too much mobility for moving supplies
21 - Land units serving as supply source no longer draw supplies
22 recursively, because the bugs there are too hard to fix to be
24 - Defending and reacting units only checked whether they could draw
25 supplies, but didn't actually draw them.
26 - load, lload, supply, assault and board no longer supply land
27 units from ships carrying them. This feature, added in 4.0.14,
28 was inconsistent with other ways to supply.
29 - Don't use automatic supply to avoid starvation at the update. It
30 adds complexity to the update. How much good it does to players
31 is highly doubtful; certainly nobody can rely on it. It isn't
32 covered by the starvation command. Ships or land units could
33 steal enough food from their sector to make it starve.
34 - lmine could only fetch shells for engineers that use ammo. The
35 stock game's engineers all do.
36 The changes listed for load and lload are actually lies, because
37 supply has been disabled there since 4.3.17.
38 * Don't let an engineer lay mines while it is on a ship or land unit,
39 or in a foreign sector.
40 * Sectors and ships no longer need shells to fire flak.
41 * Use IPv4 and v6 only when suitable interfaces are configured.
42 * Fix turn off not to fail when the message is empty. Broken in
44 * Don't nag the deity about game hours restriction in force all the
46 * Tell deity when the game is down, just like players. Also make the
47 information available in xdump, as game selector down.
48 * Corrupt mailboxes could crash the server.
49 * Fix reject accept. Broken in 4.3.4.
50 * If a player was at a prompt when the deity turned the game down, he
51 was allowed to enter one more command.
52 * Air defense is no longer separate from interception. Putting a
53 plane on air defense now merely changes where it intercepts.
54 Separate air defense added too much pointless complexity. Its
55 implementation violated design assumptions of the intercept code.
56 Because of that, the same plane could intercept both an air defense
57 mission and the planes that triggered it, and the damage it
58 received in the first interception was wiped out.
59 * Intercept the same all along the flight path. In each sector, any
60 country owning the sector, a surface ship or a land unit there gets
61 to intercept. Before, only the sector owner got to intercept,
62 except for the assembly point and the target sector. In the target
63 sector, any country owning surface ships or land units got to
64 intercept in addition to the sector owner. Thus, a sector owner
65 with surface ships or land units there got to intercept twice. The
66 sector owner did not get to intercept at the assembly point,
67 even when it was the target sector.
68 * Spotting rule changes:
69 - Ships and land units now spot overflying planes along all of the
70 flight path instead of just the target sector, and no longer
72 - Planes now spot ships and land units only when flying recon or
73 sweep, and along all of their flight path instead of just the
74 target sector. It still takes a spy plane to identify ships and
76 - Planes now spot ships and land units in a sector even when all
78 - Planes now spot all foreign ships and land units, not just
80 * Fix SAM interception for intercepts other than the first.
81 * Fix air defense and flak over sectors allied to the planes. Air
82 defense was broken in Empire 2. Flak was broken in 4.2.8.
83 * Establishing contact by spotting planes from sectors didn't work.
84 * Fix reconnaissance patrols to use sonar when any capable plane is
85 present. Before, all planes had to be capable.
86 * Fix recon and sweep not to spy after all spy planes are gone.
87 * Fix a bug that made multiple clients running on the same Windows
88 machine interfere with each other. Broken in 4.3.11.
89 * Fix enforcing game hours for players already logged in. Broken in
91 * Fix distribution not to abandon a distribution center by exporting
93 * Many fixes to load, unload, lload and lunload:
94 - Now usable for deities.
95 - Plug loopholes that let you steal foreign commodities by making
96 load/lload unload and unload/lunload load through use of negative
98 - Fix not to let you give away civilians.
99 - You can't use lload in foreign sectors or lunload with foreign
100 land units anymore. Loading stuff in foreign sectors was
101 prohibited already for ships.
102 - lload and lunload now work on foreign land units only when
103 they're explicitly named by uid. This matches behavior of load
105 - Fix to test relations of foreign object's owner to player instead
106 of the other way round.
107 * Make sure land units with maximum mobility can attack mountains.
108 * Fix land unit attack mobility cost. Broken in 4.3.6.
109 * Conditions comparing string-valued selectors like wing to unquoted
110 values are now interpreted more smartly. Before, unquoted strings
111 were prone to be interpreted as selector names even when that made
112 no sense. You still have to disambiguate truly ambiguous cases
113 like w=w for planes, e.g. as wing=w or w='w'.
114 * Fix reporting of shot spies in news. Broken in 4.3.16.
115 * Remove econfig key mission_mob_cost. Questionable feature, and
116 hasn't been used in a long time.
117 * Reserve and escort missions now have an op-area, like all the other
119 * Land units now react only when on a reserve mission. The lrange
121 * Fix a bug that could mess up mission op-area when the range of
122 ship, plane or land unit on the mission decreases, e.g. through the
124 * Reserve missions no longer give a bonus to reaction range.
126 * Code refactoring and cleanup.
128 Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
129 * LWP doesn't work with Darwin due to OS bugs, avoid it for now.
130 * Don't let ships double-retreat first on 'i' (injured) and then on
131 'h' (helpless) when shelled.
132 * Fix a bug that suppressed the "sunk!" message. Broken in 4.3.17.
133 * Log out player when maximum time per day is exceeded. Before, he
134 could remain logged in with visitor privileges only, but once
135 logged out could not log back in.
136 * If a player was at a prompt when either game hours restriction
137 started or maximum time per day was exceeded, he was allowed to
138 enter one more command.
139 * Deitying a capital failed to charge money and report news. Broken
141 * Overhaul accounting of play time, fixing minor inaccuracies.
142 * Fix parsing of 24:00 in econfig key game_hours and
144 * New option RAILWAYS.
145 * Che ages just like military reserves (1% per 24 ETUs).
146 * Permit ships to assault the sector they're in.
147 * Sectors eating less than one unit of food don't make one unit of
148 food for free anymore. They still can't starve.
149 * New concept sector terrain. Deities can use it to make sectors
150 other than wilderness redesignatable. See sect.config for more
152 * Represent play time in seconds rather than minutes. This affects
153 xdump: nat selector minused (counting minutes) is replaced by
154 timeused (counting seconds).
155 * Improved nightly build, with additional tests.
157 Changes to Empire 4.3.18 - Sat Oct 18 18:39:17 UTC 2008
158 * Fix building of planes, land units and nukes with uids that have
159 never been used before. This could crash the server on some
160 systems in certain states. Broken in 4.3.17.
161 * Improved nightly build, with restructured and extended tests.
163 Changes to Empire 4.3.17 - Sat Sep 20 16:07:44 UTC 2008
164 * Fix standalone client build for Windows. Broken in 4.3.11.
165 * Disable automatic supply of land units on load for now, it's broken
166 in a highly abusable way.
167 * Make trade show exactly what's on sale, remove option SHOW_PLANE.
168 * Stop ships, planes, land units and nukes on violent takeover, just
170 * Wipe orders when ships, planes, land units and nukes are taken over
171 violently or given away peacefully. Fleet, wing, army and mission
172 were already cleared in many, but not all cases. Other orders were
173 never cleared: mission op areas (visible in xdump), ship autonav
174 orders, ship sail path (including ship to follow and mobility
175 quota), land unit retreat orders, plane range limit, and land unit
177 * Fix takeover of stuff by attack, assault, board, lboard, paradrop
179 - Corrupt land unit file could lead to infinite recursion.
180 - Take over nuke armed on plane along with the plane. Broken in
182 - Taking over land units with negative mobility increased mobility
183 to zero. Ditto for planes embarked on ships or land units.
184 * Fix a bug that made set and xdump not recognize unused trade lots
186 * Fix giving away stuff by trading it:
187 - When an armed nuke is sold separately from its plane, take it off
188 the plane. You couldn't do that before 4.3.3.
189 - Give away nuke armed on sold plane along with the plane. Broken
191 - Don't zero mobility of planes and land units on sold ships.
192 * Fix giving away stuff by unloading from its carrier: Give away any
193 nukes armed on planes (broken in 4.3.3) and land units loaded on
194 land units. The latter can't happen in the stock game.
195 * Fix giving away stuff by scrapping or scuttling its carrier:
197 - Disarm the nuke from a plane instead of destroying it.
198 - Give away any loaded land units and planes, too.
200 - Fix scuttle to ask for confirmation when scuttling a tradeship in
201 an unsuitable sector even when the tradeship is pirated. Broken
203 - Fix scuttle to require 2% harbor efficiency for a trade ship to
204 pay. Also require at least friendly relations.
205 - Make autonav refuse scuttle orders in unsuitable sectors.
206 * Clean up rules on where you can scrap stuff:
207 - Ships in own or friendly, efficient harbors (relations used not
208 to matter, contrary to info)
209 - Planes in own or allied, efficient airfields (friendly used to
210 work as well, contrary to info)
211 - Land units in any own or allied sector (relations used not to
212 matter, and you couldn't scrap them on ships)
213 Also tell player why something can't be scrapped instead of
214 ignoring it silently.
215 * Rewrite the broken code to move land units, planes and nukes along
216 with their carrier. The old code was a hack that didn't update
217 timestamps (so incremental dumps didn't pick up the movement), and
218 it didn't cover all uses. The update, in particular, was prone to
219 see cargo in old locations, which could screw up repairs.
220 * Expire lost items at the update instead of continuously.
221 * Replace econfig key lost_items_timeout by lost_keep_hours.
222 * Minor Windows threading fixes.
223 * Journal now uses human-readable names to identify threads.
224 * Ship and land unit load counters are no longer stored in game
225 state, because they duplicate information already there. Same for
226 the type of nuke loaded on a plane. Remove field nuketype from
227 xdump plane. Clients can simply find the plane's nuke instead.
228 * Ship and land unit load counts as displayed by ship, sdump, land,
229 ldump, ship selectors nplane, nxlight, nchoppers, nland, and land
230 selectors nxlight, nland are now reliable. They used to get out of
232 * Ship load counts now reflect what is loaded, not how it is stored.
233 For instance, if a light carrier, capable of carrying 4 x-lights
234 and 20 light planes carries nothing but 5 sams, we now have
235 nxlight=5, nplane=0 instead of nxlight=4, nplane=1.
236 * New cargo lists data structure to let code find loaded planes, land
237 units and nukes easily and efficiently.
238 * Revamped upkeep of lost file. It should be reliable now.
239 * Disable the ill-advised error recovery on sector access that swept
240 bugs under the carpet rather than recovering from them.
241 * Occupied sectors no longer revert to the old owner when all
242 military and land units go away. This feature was added in
243 Chainsaw 3. It wasn't integrated properly with the che code
244 (things went wrong when che killed all defenders, but couldn't
245 convert the sector due to its loyalty), and combat code (if an
246 attack killed off all local defenders and got defeated by reacting
247 units, the sector changed ownership anyway, silently).
248 * Include destination coordinates in interception and plane mission
250 * Client could misdiagnose redirections and executes as unauthorized,
251 or die outright. Broken in 4.3.11.
252 * Fix xdump realm to dump player instead of absolute coordinates.
253 Disclosed the true origin. Broken in 4.3.0.
254 * Fix spy to reliably avoid spying same sector more than once.
255 * The map drawing code could smash the heap when the world was
257 * When a satellite's launch trajectory was off, its coordinates could
258 get screwed up, which made it invisible in skywatch.
259 * Fix several bugs that made the path command screw up when the path
261 * Fix the default size of the map shown by move, test and transport
263 * Fix bugs that could make arguments in area or dist syntax miss
264 ships, planes, land units and nukes at the border of the selected
265 area, if that area spans the whole world. In sufficiently small
266 worlds, it could also make radar miss satellites and ships, sonar
267 miss ships, satellite miss ships and land units, nuclear
268 detonations miss ships, planes, land units and nukes, automatic
269 supply miss ship and land unit supply sources, ships and land units
270 fail to return fire, ships fail to fire support.
271 * Maps sometimes showed x-coordinates as three lines instead of two
273 * Improved nightly build, tests in particular.
274 * Code refactoring and cleanup.
276 Changes to Empire 4.3.16 - Sat Aug 9 15:56:52 UTC 2008
277 * Production command incorrectly limited the number of graduates,
278 happy strollers, technological breakthroughs and medical
279 discoveries produced by a sector to 999. Broken in 4.2.15.
280 * Fix a bug in improve that could let you spend more money than you
282 * Fix work command not to spend more mobility than requested, and to
283 round mobility use randomly instead of down.
284 * Commands demobilize, convert and work no longer let you spend more
285 money than you have. Commands demobilize and convert no longer ask
286 for confirmation before spending more than half your money. Saving
287 that feature would have been more work than it's worth.
288 * Remove undocumented key 'd' at bomb ship, plane and land unit
290 * Fix land unit flak when pin-bombed to match flak when overflown:
291 proportional to efficiency, and randomly rounded. Was missed in
293 * Don't permit bombing of embarked planes and land units.
294 * Fix capital maintenance to charge at 60% efficiency.
295 * launch command now requires only 40% plane efficiency, for
296 consistency with other ways to launch missiles.
297 * Disable collateral damage when automatically launched missiles miss
298 their target. Collateral damage was done even when the launch
299 failed or the missile got intercepted. It's been disabled for
300 manually launched missiles since 4.0.18, for the same reason.
301 * Fix a bug that corrupted the lostitems file. Broken in 4.3.12.
302 * Show command changes:
303 - Move product information from "show sect c" into new "show
304 product", and reformat it to be easier to understand.
305 - New column navigability in "show sect s".
306 - "show sect s" now shows the packing bonus type instead of
307 selected packing bonuses. "show item" shows the actual bonuses
309 - "show sect b" now shows the usual values in addition to unusual
311 * Fix interdiction to obey op-area for missiles.
312 * Fix a bug that caused a stale sources.mk to be distributed in the
313 4.3.14 an 4.3.15 tarballs. The latter does not build out of the
315 * Don't strip tab characters from quoted command arguments. Broken
317 * shutdown commands now always take effect immediately. Before, they
318 could be delayed by up to a minute.
319 * shutdown could start multiple shutdown threads when you initiated a
320 shutdown shortly after cancelling one. This screwed up the timing
322 * Deity syntax of zdone changed, and is now documented in info.
323 * The threshold command could be tricked into accepting negative
325 * Fix designate to always write updated bmap to disk.
326 * Fix bomb to fail on empty <pin|strat> argument instead of flying
328 * Fix a bug in distribute that screwed up the current sector's
329 distribution center when the command got aborted.
330 * Commands arm, bomb, deliver, drop, fire, fly, paradrop, recon,
331 lmine, order, power, range, sail, shutdown, sweep and tend did not
332 honor command abortion at some prompts.
333 * Fix a bug in handling of EOF from client that could bite in the
335 - EOF at target prompts for bombing commodities, ships, planes and
336 land units sent the server into an infinite loop that ate all
338 - EOF at sail's path prompt crashed the server.
339 - EOF at some prompts in deliver, designate, fly, morale, zdone,
340 attack and assault didn't abort the command.
342 * Selector terr is now the same as terr0 for mortal players, and
343 dterr for deities. This matches how the territory command works.
344 Unfortunately, this required us to rename xdump sect field terr to
345 terr0. Sorry about that.
346 * Fix bomb not to let you bomb dead ships and land units.
347 * Make the retreat command a bit more helpful on retreat conditions,
348 and make it fail on bad conditions.
349 * Fix the mapper scripts. Broken in 4.2.0.
350 * Fix flying commands not to let planes do double duty as escorts.
352 * When a minesweeper hit a mine after sweeping, the mine wasn't used
353 up. If it sank the minesweeper, the code accessed freed memory,
354 which could clobber the ship file or worse. Broken in 4.0.17.
355 * Don't let non-light units board ships that can't carry them.
356 * Capitals can now employ up to 1000 civilians instead of 999.
357 * Spy command changes:
358 - Spy now requires sector military. Before, presence of land units
359 was sufficient, but spies shot were only deduced from sector
360 military. If you lost more spies than you had sector military,
361 the rest came back from the dead.
362 - Spy no longer ignores non-sea sectors without civilians, military
364 - Remove columns lnd, pln from spy report. The values didn't match
365 the reported land units and planes, and could leak the presence
367 - Establish contact when spy succeeds even though the spy was
369 * Fix news reporting and damage when land units interdict ships in
370 sectors other than sea.
371 * Fix land unit return fire damage to ships to take accuracy into
372 account, like the fire command and interdiction does.
373 * Remove the inconsistent shelling damage reduction for range. Fire
374 command got damage reduced by 10-20% with a chance depending on
375 range ("Wind deflects shells"). Ships interdicting got it reduced
376 by half. Other ways to shell did not get damage reduced for range.
377 * Fix ground combat to report defending land units. Broken in 4.3.4.
378 * Info file and documentation fixes and improvements.
380 Changes to Empire 4.3.15 - Sun May 18 08:59:30 UTC 2008
381 * The edit command keys deprecated in 4.3.10 are now gone.
382 * fairland now obeys game file locks.
383 * Do not leak world creation time in files utility, because that
384 facilitates attacks against fairland's PRNG. Broken in 4.3.12.
385 * Fix starvation not to starve one more than it should. The last man
386 on a boat or land unit now can't starve anymore.
387 * Fix a crash bug in satellite. Broken in 4.2.7 and not fixed
389 * Fix a coordinate normalization bug that could theoretically lead to
390 buffer overruns and other unpleasantness. None have been
391 reproduced, though. Broken in 4.3.12.
392 * Remove option FUEL. The abstract idea of tying ships and land
393 units to a logistical tether is sound, the concrete implementation
394 as option FUEL is flawed. It adds too much busy-work to the game
395 to be enjoyable. It hasn't been enabled in a public game for
396 years. The code implementing it is ugly, repetitive, and a burden
397 to maintain. The edit command still accepts and ignores the fuel
398 keys for compatibility, but they are deprecated.
399 * Fix pin-bomb not to report subs when there are none.
400 * You now have to take a capital to capture the victim's money, loans
401 or market lots. Merely obliterating the capital doesn't cut it.
402 It still makes the victim lose money, though.
403 * Fix a bug that could theoretically allow sacking of non-existant
404 capitals of visitors, deities and such.
405 * You now gain BTUs and MOB_ACCESS mobility before the first update
406 again. You didn't since 4.3.10 introduced the ETU clock.
407 * Fix edit to detect when the edited object changes while it's being
409 * Fix xdump nat for relations: it got HIDDEN backwards. Broken in
411 * Fix origin command not to prompt twice for its argument. Broken in
413 * Info file improvements.
415 Changes to Empire 4.3.14 - Mon May 5 04:57:03 UTC 2008
416 * Another round of fixes to the fire command:
417 - Don't disclose where the target retreated to.
418 - Charge the target shells for returning fire.
419 - Always use guns when the target is out of range, even if it's a
420 submarine. Before, the difference in shell use disclosed whether
421 the target is a submarine. Loophole opened in 4.3.12.
422 - Make depth charges again work with just one shell. Failing the
423 command in that case lets players find out whether the target is
424 a submarine. Loophole opened in 4.3.12.
425 - Detect when the firing sector, ship or land unit changes across
426 the target prompt. Abusable.
427 * Fix parsing of anchor-relative time in update schedule. Broken in
429 * Fix logging of player input in the journal to include command
430 interruption and EOF.
431 * Fix oversights in 4.3.12's change to keep track of flying planes:
432 planes could be erroneously reported damaged by their own ground
433 strikes. Happened with missions and the launch command.
434 * Fix load not load hardened missiles.
435 * Fix harden not to harden missiles loaded on land units.
436 * New server option -E to choose what to do on recoverable internal
437 error. You can now make the server dump core and keep going (not
438 implemented for Windows). New econfig key post_crash_dump_hook to
439 run a program after crash-dumping. See scripts/savecore for an
441 * Journal entries are now flushed to disk right away even when the
442 server is not running in debug mode.
443 * Don't let land units load trains.
444 * Allow deity to display power report for all types of countries,
446 * Fix designate's check for disallowed sector types. Broken in
448 * Documentation fixes.
450 Changes to Empire 4.3.13 - Tue Apr 15 19:03:11 UTC 2008
451 * Work around strptime() lossage on some systems. Fixes the parsing
452 of the schedule file there.
453 * New selector maxnoc for xdump version.
454 * Fix initialization of realms in newcap. Broken in 4.3.12.
455 * Fix add for status arguments active, god, delete. Broken in
457 * Info file, manual page and documentation fixes.
459 Changes to Empire 4.3.12 - Wed Apr 2 05:35:06 UTC 2008
460 * Fix rounding error in update that could result in more babies than
461 food permits, and negative food.
462 * Fix a bug that could lead to unfair thread scheduling under
464 * Fix ship and land unit missile interdiction and ballistic missile
465 interception to require a proper base. Before, missiles could
466 launch from anywhere for that.
468 - Don't allow launching from unowned sectors.
469 - Don't destroy missiles stuck on foreign ships.
470 - Use up the supplies required for launching an asat only when it
472 - Don't ignore satellites' fuel use.
473 * Deity command newcap now requires its second argument (sanctuary
474 coordinates). Before, it tried to pick a suitable location when
475 none was given. The code implementing this feature had problems,
476 and it's not worth fixing, because it is obscure, and rarely (if
477 ever) used: no conscientious deity would use it for a real game,
478 and for blitzes fairland does a better job.
479 * Keep track of flying planes properly. This fixes a number of bugs:
480 - While the bomb command awaited pin-bombing target input from the
481 player, other players could interact with the pin-bombers and
482 escorts as if they were sitting in their bases: spy them, damage,
483 capture, load, unload, or upgrade them, even get intercepted by
484 them. But any changes to those planes were wiped out when they
486 - The bomb command could bomb its own escorts, directly (pin-bomb
487 planes) or through collateral damage, strategic sector damage,
488 collapsing bridges or nuke damage. The damage to the escorts was
489 wiped out when they landed.
490 - If you asked for a plane to fly both in the primary mission and
491 escort, you got charged fuel for two sorties instead of one.
492 * Plug memory leaks in plane interception.
493 * Fix trade not to let the buyer teleport satellites (not in orbit)
494 and asats to an arbitrary sector. Abusable, because abms
495 intercepted from anywhere, and satellites could be launched from
497 * The PRNG seed is now logged in the journal.
498 * Fix nightly build for Windows.
499 * Fix crash bug that bit when custom tables contained columns names
500 that existed, but weren't supposed to be in the custom table.
501 * New timestamp selector for commodity, country, game, loan, nation,
502 news, realm, trade, treaty to support incremental xdump.
503 * Deity commands newcap and add wipe the nation more thoroughly. add
504 no longer touches relations and flags for status active and god.
505 * New utility program empdump to export and import game state as
506 plain text. Check its manual for details, including limitations.
507 * Plane, ship and land unit stats are no longer stored as game state,
508 but recomputed from tech and base stats as needed.
509 * xdump ver is no longer a special case. Syntax "xdump ver" is now
510 deprecated. Use "xdump version *".
511 * Fire and torpedo cleanup and bug hunt:
512 - Plug memory leak in fire command.
513 - Fix ammunition use when returning fire: resupply could lose
514 shells when returning fire to multiple targets, and land units
515 were charged per target instead of just once.
516 - Interdicting land units now resupply shells automatically, for
517 consistency with other ways to fire.
518 - torpedo and fire no longer resupply shells automatically. The
519 latter used to resupply land units only.
520 - Land units no longer have to be in supply to fire actively, for
521 consistency with other ways to fire.
522 - Submarines with zero mobility can no longer interdict, for
523 consistency with other ways to torpedo.
524 - Fix bugs that let submarines without capability torp use
525 torpedoes to return fire and interdict.
526 - Fix torpedo command not to require a line of sight for return
527 fire and depth charges, and to use torpedo range instead of
528 firing range for return torpedoes.
529 - Active fire and interdiction didn't work for ships with zero
530 firing range, even though return fire and support did. No such
531 ships exist in the stock game.
532 - Let land units with zero firing range and non-zero firing damage
533 fire, for consistency with ships. No such units exist in the
535 - Ships required different numbers of military to operate their
536 guns for the various kinds of fire. Unify to require 2*N-1
537 military to fire N guns.
538 - Ship ammunition use differed for the various kinds of fire.
539 Unify to use one shell per two guns.
540 - Forts could fire support even when there were not enough mil.
541 - Fix automatic shell resupply in several places to supply exactly
542 the shells actually fired, no more, no less.
543 * Change depth charges back to how they are documented and worked
544 before 4.0.6, mostly: require no guns, one military, do damage like
545 shell fire from three guns (before 4.0.6: two guns), use two
546 shells. In 4.0.6's model, they worked exactly like shell fire
547 (require guns and gun crew, non-zero firing range, damage and
548 ammunition use scales with available guns), except for missions,
549 which was a bug. Note that depth charge damage for all ships is
550 now like fire from three guns for two shells. No change for dd; af
551 did two gun damage for one shell before, and nas did four gun
552 damage for two shells.
553 * The edit command keys deprecated in 4.3.3 are now gone.
554 * Fix build not to screw up automatic dependencies on certain compile
556 * Fix a bug that could prevent repeated news from properly
557 aggregating into one news item.
558 * Properly initialize all bits in game state files, even those that
560 * Fix explore's test for stopping on a splashed bridge. The bug made
561 explore print to a bogus message.
562 * Fix spelling of symbol airburst in table plane-flags. This could
564 * Change designate not to check total cost before executing the
565 redesignation. The code implementing that was buggy and too ugly
566 to live. Designate doesn't cost anything in the stock game.
567 * Always charge land units at least as much mobility for assaulting
568 from non-landing ships as from landing ships. Before, marines lost
569 all mobility when assaulting from a non-landing ship, which could
570 be less than what the same assault costs from a landing ship (half
572 * Fix LWP's stack initialization for -s. It caused crashes on some
574 * Fix confused and buggy bridge splashing code:
575 - Flying planes could be reported drowned.
576 - Pin-bombing a bridge head failed to collapse bridge spans for
577 lack of support, unless the pin-bombing caused collateral damage.
578 - Corrupt sector file could lead to infinite recursion.
579 * Relative names now work for econfig keys data and info.
580 * Fix utility programs to abort on internal errors. They used to
581 print a message and attempt to recover.
582 * Fix off-by-one in fairland that ate the last expansion island.
583 * Switch from CVS to git.
584 * Code refactoring and cleanup.
586 * Info file, manual page and documentation fixes and updates.
588 Changes to Empire 4.3.11 - Tue Jan 1 18:57:38 UTC 2008
589 * New sector selector elev. It's set by fairland, but has no effect
590 on the game. It can be useful for deities to customize a world
592 * The client now copes with ids greater than 15. The Empire
593 protocol currently uses 14 ids.
594 * Rewrite the client's code for reading server output during login.
595 The old code could write one byte beyond the end of the buffer
596 (theoretically a remote hole), got confused by long lines, and
597 lines that didn't arrive in one piece.
598 * Long country name, password or user name crashed the client.
599 * Fix xdump not to deny access to game state tables when maximum
600 minutes per day are exceeded.
601 * The server considers a country bankrupt when its treasury is
602 negative. Except when it doesn't. Fix that:
603 - report misreported countries with $0 as broke.
604 - If a command spent a few cents more than you had, commands requiring
605 money became unavailable even when rounding brought you back to
606 $0. But logging out and back in then bankrupted you.
607 - If your treasury rose to exactly $0, commands requiring money
608 remained unavailable.
609 - If you had $0, sectors didn't build and sectors and ships didn't
610 produce at the update.
611 * Fix a bug in trade that made your money evaporate when a trade fell
612 through because you couldn't fully pay. This bug was there since
613 the introduction of the market in 4.0.0. It got aggravated by the
614 removal of forced loans in 4.3.0.
615 * Fix printing of the new group in army, fleet and wing. Broken in
617 * Fix flash not to screw up the message when the first argument
618 contains white-space.
619 * Don't let planes intercept when they are stuck in foreign bases, on
620 inefficient ships or land units, or on land units loaded on ships
622 * Fix a bug that made interception require petrol to be present even
623 for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
624 defense missions weren't affected.
625 * fairland and setsector now limit fertility to 100 instead of 120,
626 like the other resources.
627 * Generalize the autonav hack for fishing boats so it covers oil
629 * Fix bug in path command that made it swallow every other step.
631 * The execute command no longer supports redirections and execute in
632 batch files. Flaws in the Empire protocol make it next to
633 impossible for clients to implement that correctly. See
634 doc/clients-howto for an explanation.
635 * Rewrite much of the client's code for sending commands and
636 receiving server output:
637 - No longer blocks on sending commands, which could deadlock the
639 - Fix race condition that could cause server output to be discarded
640 on EOF on standard input.
641 - Don't discard server output when reading standard input fails.
642 - Fix error handling for execute and other, more obscure cases.
643 - More rigorous error checking for redirections and execute.
644 Clearer error messages, too.
645 - Fix execute redirected to file or pipe. Believed to be broken in
647 - The client now creates files for redirections with the same
648 permissions whether the redirection is in a pipe or not. Before,
649 redirections without a pipe created files with no permissions for
650 group and others. This change may make your redirected output
651 visible to other users on your system. Use the usual controls,
652 like umask, to restrict permissions to your liking.
653 - Reject unexpected redirections (violating the protocol). Before,
654 they silently replaced the current one, and in the case of pipes
655 leaked file descriptors and memory.
656 - Redirections in batch files are not implemented. They didn't
657 quite work before, and could leak memory and file descriptors. A
658 flaw in the Empire protocol makes them next to impossible to
660 - The execute command in batch files is not implemented. A flaw in
661 the Empire protocol makes this practically useless anyway.
662 - Old code leaked memory in various places.
663 - Unfortunate incompatibility with older servers: if you type the
664 EOF character (normally ^D) at an argument prompt, the session
665 hangs. Use the interrupt character (normally ^C) to get out.
666 * The client now supports options -h and -v.
667 * The client no longer zaps its command line in a lame attempt at
668 protecting users who foolishly specify passwords on the command
669 line. Zapping annoys system administrators and creates a false
671 * Journal entries are now flushed to disk right away when the server
672 is running in debug mode.
673 * Fix bugs in load that could make loading operations fail noisily
674 instead of silently on some systems.
675 * Server now reliably shuts down session when it receives an
676 end-of-file condition from the client. Before, it merely failed
677 the current command when it got it at an argument prompt.
678 * Fix bug in execute that could crash the server on some systems when
679 it prompts for the argument.
680 * Fix bug that let you check whether a non-allied carrier is
681 efficient enough for takeoff when one of your planes got stuck
683 * Fix bug that let you attempt to escort a one-way mission to a
684 carrier with non-light, non-interceptor escorts. Such planes don't
685 fit on carriers, and the command then failed with a bogus error
686 message. Before 4.2.17, the planes flew, and the escorts were
688 * Change the rules for fitting planes on ships slightly, so that the
689 order of loading no longer matters. Choppers and x-lights can now
690 use plane slots even when not light. X-light choppers, which don't
691 exist in the stock game, can no longer use x-light slots.
692 * The server now keeps its log file open, just like the journal.
693 * New server option -R to set the PRNG seed. This is for
694 reproducible tests. Change the Windows-only service uninstall
695 options from -r/-R to -u/-U.
696 * Supply a real PRNG for Windows instead of the leaky water-pistol
698 * Threads sleeping until a specified time could return early under
699 Windows. This could cause missed updates. Broken in 4.3.10.
700 * Fix missing newline in show updates.
701 * Power report didn't factor tech into power correctly. Broken in
703 * Code refactoring and cleanup.
704 * Info file and documentation fixes and updates.
706 Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
707 * Bridge spans now cost $1000 instead of $2000, and bridge towers
708 $3000 instead of $7500.
709 * The Windows port now supports IPv6, but it still needs to be
710 enabled manually at compile-time.
711 * The custom table reader detects more errors.
712 * Do not leak world creation time in files and fairland, because
713 that facilitates attacks against the PRNG. This misfeature crept
715 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
716 Using it required manual hackery since 4.3.0.
717 * Plug file descriptor leak in add command.
718 * Don't kill player connections violently when their thread appears
719 to be hung. Threads being aborted by update or shutdown could be
720 misidentified as hung, and the violence could lead to resource
721 leaks, locked out updates, and corrupted game state.
722 * Fix LWP to reliably wake up threads sleeping for a time. Before,
723 players with a sufficiently fast connection could starve out system
724 threads, including the update.
725 * Fix a class of bugs that made commands behave differently while the
726 update is attempting to take control:
727 - No MOB_ACCESS mobility was gained.
728 - Telegrams were miscounted.
729 - Bulletins got misfiled as production reports.
730 - The navigate command ignored sail paths.
731 - The declare command was more quiet, and declarations of war
732 failed silently when SLOW_WAR was enabled.
733 - Many messages got misdirected to bulletins.
734 Some of these bugs go back all the way to Empire 2, ca 1995.
735 * New deity command reload, effect similar to SIGHUP.
736 * Not voting for a demand update no longer lets you veto further
737 demand updates. This feature was flawed (it encourages players to
738 vote late so that they can tactically vote no and thus build up
739 veto rights), virtually unused, and buggy. The edit command still
740 accepts and ignores the country key 'U' for compatibility, but it
742 * Fix zdone not to claim to have triggered an update when they're
744 * New update scheduler and ETU clock:
745 - New schedule file. See doc/schedule for how to use it. Replaces
746 econfig keys update_policy, adj_update, update_times, hourslop,
747 blitz_time. A change of schedule does not require a server
749 - The force command can no longer force updates in the future.
750 Edit the schedule file for that.
751 - New command show updates to show the update schedule. Obsoletes
753 - New xdump game and xdump updates.
754 - New utility program empsched to help test update schedules.
755 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
756 by econfig key update_demand.
757 - econfig key update_demandtimes no longer applies to scheduled
759 - You now receive new BTUs at the update in addition to login.
760 - You now always gain the same BTUs and MOB_ACCESS mobility per
761 turn, even when the update schedule changes, updates get missed,
762 or unscheduled demand updates run.
763 - Remove the mobupdate command, because porting it to the new ETU
764 clock is not worth it.
765 * Redesign of synchronization between commands, update and shutdown,
766 and how updates are triggered:
767 - Simplify update to a single thread waiting for the trigger.
768 Before, three update threads had to perform a carefully
769 choreographed dance to make updates happen. The dance relied on
770 thread priorities for correctness, which are only implemented by
771 LWP. With pthreads and under Windows, demand updates were prone
772 to two update threads starting up concurrently. Even with LWP,
773 forced and demand updates could lead to double updates.
774 - Use a lock for synchronization: commands take it shared, update
775 and shutdown take it exclusive. This makes update and shutdown
776 block until all aborted commands terminated and gave up their
777 lock. Before, they proceeded blindly after waiting two or one
778 seconds respectively, which was cheesy and unsafe.
779 - New commands no longer fail while the update is pending, they are
780 delayed until after the update.
781 - New commands can no longer start during shutdown. Before, they
782 could, but risked getting killed violently, possibly corrupting
784 - Fix command execution so that commands blocked in writing
785 redirections are abortable. The bug allowed players to delay
786 update and shutdown indefinitely.
787 - Fix shutdown not to let player threads block on output. This
788 let players delay shutdown indefinitely.
789 - Fix reading of player input not to block again after update or
790 shutdown aborted it. The bug allowed players to delay update and
791 shutdown indefinitely.
792 * Thread priorities are only implemented by LWP and no longer used.
793 With LWP, they let players with a sufficiently fast connection
794 starve out the threads that clean the lost file and kill idle
795 connections. Drop them.
796 * Show nuke rounded required research incorrectly.
797 * Log unprintable characters as octal escapes rather than question
798 marks in the journal file.
799 * The files program no longer changes permissions of existing files.
800 * The files program now creates all files with permissions ug=rw and
801 all directories ug=rwx, modified by umask.
802 * Fix a bug that could make arm, disarm and nuke detonation work with
803 a used-up nuke instead of the armed one. This could be abused to
804 detonate nukes multiple times. Broken in 4.3.3.
805 * Fix nuke detonation output for zero blast radius.
806 * Plug memory leaks in thread code.
807 * Fix a bug that made LWP I/O wakeup unreliable.
808 * New march sub-command v for view.
809 * Journal was initialized before threads were, which was wrong.
810 * Fix server not to create a journal on SIGHUP when it is disabled.
811 * shutdown 0 now requests immediate shutdown instead of cancellation
812 of a pending shutdown. shutdown -1 now cancels.
813 * flash and wall no longer split long message lines.
814 * Fix a bug in collect that screwed up a fully collected loan instead
815 of deleting it. The screwed up loan could not be sharked or
816 collected, but it could be repaid.
817 * Remove the wait command, it's been broken and restricted to deity
818 since Empire 2, ca. 1995.
819 * Budget failed to take sector production into account for predicting
820 unit repairs. Before 4.3.6, this bug bit only when you fooled
821 around with budget priorities.
822 * When unit repairs are limited by materials, the efficiency gain is
824 * Ship repairs outside harbors and plane repairs by carriers used to
825 consume commodities when and as far as available. Now, they
826 consume the same fraction of the real cost of each commodity,
827 i.e. commodity use is limited by the most scarce commodity.
828 Neither old nor new behavior make much sense, but the new code is
830 * Code refactoring and cleanup, in particular to make the Windows
833 * Info file and manual page updates. All manual pages are now
834 installed in section 6.
836 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
837 * Fix declare to prevent the deity from changing relations for a
838 player to self. Allow the deity to set the relations of a player
840 * Fix arm not to put the same nuke on multiple planes (broken in
842 * New option AUTO_POWER.
843 * Sectors now repair allied land units.
844 * Sectors now repair only own and allied planes.
845 * Fix repair of planes on foreign carriers: repair allied planes,
846 ignore the others. Before 4.3.3, carriers destroyed rather than
847 repaired foreign planes. Since 4.3.3, foreign planes were treated
848 as recoverable error.
849 * Fix automatic fortification of land units to use all excess
850 mobility even when mobility delta exceeds mobility maximum.
851 * Disable automatic fortification of land units when MOB_ACCESS is
852 on, because it is prohibitively slow then (broken in 4.2.13).
853 * Budget now shows level production (tech, education, research and
854 happiness) rounded instead of randomly rounded.
855 * Fix update not to randomly flush small level production to zero.
856 * Fix overly restrictive game file locking under Windows (broken in
858 * Fix navigate to charge mobility for sweeping mines without moving
862 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
863 * Ships no longer produce stuff when the government is broke.
864 * Fix land unit casualties in revolts.
865 * Fix security units not to raid friendly che.
866 * Fix update sequence to ensure stopped sectors don't work on the
867 ships, planes and land units in the sector. Before 4.3.6, this bug
868 bit only when you fooled around with budget priorities.
869 * Fix canal loading (was broken in 4.3.0).
870 * Fix tend not to tend land units that could not be loaded.
871 * Make xdump command available before break, but deny access to game
873 * Lock game files to prevent concurrent access by multiple programs.
874 fairland does not yet obey the lock.
875 * Fix production to consider sector item limit.
876 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
877 * Enhanced mapping sub-commands in move, test, explore and transport.
881 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
882 * Sanctuaries are again fully populated with civilians (4.3.6 changed
883 the limit, but not the population). Food is now spread evenly
885 * Fix path finder to find shortest naval and aerial paths again
887 * transport's map sub-command now does the right thing for a unit
889 * Fix bug in map sub-command of move, explore and transport that
890 passed junk to map command. Could theoretically crash.
891 * Food need reported by starvation was one short for sectors without
893 * Change land unit ammunition use back to what it was before 4.2.3.
894 This lets deities customize ammunition use independent of damage.
895 It also substantially reduces ammunition consumption at high tech.
896 * navigation and march enhancements:
897 - Sub-command 'f' now takes an optional ship / land unit number.
898 - Mapping sub-commands now take an optional ship / land unit
900 - New sub-command 'd' to drop mines.
901 * Let minesweepers retreat at their full speed (missed in 4.3.6).
902 * SUPER_BARS cannot be harmed, so don't interdict them.
903 * Don't let trains and non-trains march together for now, because the
904 march code isn't prepared for that.
905 * New mapping flag 'n' to show nukes.
906 * Mapping flag '*' now shows nukes as well.
907 * New command nbmap to bmap around a nuke. Overload command nmap to
908 map around a nuke when given a nuke argument.
909 * Fix an inconsistency that gave tactical bombers a small bonus
910 vs. flak when pin-bombing.
911 * Fix production to show the designation that actually produces, not
912 the designation as it is now (broken in 4.3.6).
913 * Fix accidental whitespace change in output of sdump, pdump and
914 ldump that crept into 4.3.5.
915 * Support user-defined sector types and products in custom tables,
916 not just customization of existing ones.
917 * Fix off-by-one bug in budget that used to be masked by budget
918 priorities until their demise in 4.3.6. The bug could crash the
919 game on certain systems.
923 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
924 * The shutdown command now terminates the server process correctly
925 even with LinuxThreads pthreads under Linux 2.4 and earlier.
926 * Cope with old versions of groff (broken in 4.3.0).
927 * You can now arm allied planes with nukes.
928 * Taking a nuke off a plane gives it to the sector owner again.
929 Feature was accidentally dropped in 4.3.3. Recipient must be
931 * Naval path went bananas for impassable end sectors (broken in
933 * New econfig key disabled_commands.
934 * New territory selector dterr, restricted to deities. The territory
935 command defaults to it for deities.
936 * Let land units attack as long as they have positive mobility,
937 except for high-mobility terrain (mountains), where the rules
938 remain as they were: land units need to have all the mobility
939 charged for the attack, not counting combat and moving in to
940 occupy. Rationale: Making sure your land units reach attack
941 positions with enough mobility left is a pain in the neck.
942 Requiring only positive mobility is friendlier, but allowed rushing
943 of mountains, so we make an exception there.
944 * Can typeset info pages as PostScript. Result isn't exactly pretty.
945 * Support disabling of infrastructure in infra custom table. Remove
946 redundant option DEFENSE_INFRA. show command now shows only enabled
948 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
949 pmap sbmap, smap (broken in 4.3.1).
950 * New, simpler sector mobility cost formula:
951 - The basic cost is still a linear function of sector efficiency,
952 with customizable cost at 0% and at 100%. The latter used to be
953 derived from the former. The show command shows both parameters
955 - Mountains are no longer a special case.
956 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
957 to 1.304, highway, bridge head, bridge span and bridge tower
958 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
959 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
960 players can designate now cost the same at 0%. That's a feature.
961 - Road infrastructure now reduces cost up to 90%, linear in road
962 efficiency (used to be close to that, but non-linear). Same for
963 rail infrastructure, but 99%. Adapted from Ice World V.
964 - Double land unit minimum cost to 0.02, to slow them down on
966 - Change land unit cost penalty in newly taken land to an extra 0.2
967 instead of a minimum of 0.2, to reduce penetration depth.
968 * Reduce bridge head defense and collect value to match highway's.
969 * sinfrastructure displayed bogus rail mobility costs when there was
971 * Retreating engineers took full landmine damage instead of half.
972 * Fix socket creation code not to print a null pointer.
973 * Fix login option code not to search beyond end of table (broken in
975 * Spy planes and satellites can no longer spot landspies.
976 * Spy planes can now spot surface ships at sea. They can no longer
977 spot land units loaded on ships or land units.
978 * Fix train retreat mobility cost, and don't permit retreat off rail.
979 * Change maximum population to 100 for plains (was 49), mountains
980 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
981 the other habitable sector types (was 999).
982 * Let minesweepers navigate at the speed their stats indicate by
983 letting them sweep on the move at no extra mobility charge.
984 * Reduce chance for planes to abort from 100-eff (if eff<80) to
985 80-eff. This should make it easier to punch through air defense,
986 flak in particular, and increase the risk of getting shot down.
987 * Ship and land unit flak intensity is now proportional to efficiency.
988 * Ship and land unit flak intensity is no longer scaled by the tech
989 of the owner of the last thing firing. It's still scaled by each
991 * All ships and land units firing flak now spot the plane and are
992 spotted by the plane. Previously, spotting stopped as soon as flak
994 * Inefficient land units were overcharged mobility when reacting.
995 Broken when Empire3 changed land unit mobility use not to depend on
996 efficiency, except for supply units.
997 * New journal file to log complete player input plus selected
998 important events. Controlled by new econfig key keep_journal, off
1000 * Fix unsafe shutdown on SIGINT and SIGTERM.
1001 * Fix land unit path finding: paths weren't always cheapest (broken
1002 in 4.0.2), and trains could be sent down paths without rail (never
1003 worked). Also fixes unit reaction path cost.
1004 * The custom table reader can now deal with sector, item, product and
1005 infra tables more comfortably.
1006 * Remove option BIG_CITY. Deities can customize the sect table to
1007 get the same effect.
1008 * Many more selectors can now be compared with names, not just
1009 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
1010 not fully work for queer names like &&&.
1011 * Let land units on missions support, just like ships.
1012 * Don't let units loaded on a train react.
1013 * Change update sequence to repair ships, planes and land units after
1014 sectors produce. This makes repairs use new avail instead of old.
1015 * Let players stop and start units.
1016 * Remove budget priorities.
1017 * Make plane report easier to understand.
1018 * Change land report to show carriers in the same format as plane and
1021 * Info file and manual page fixes.
1023 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
1024 * In conditionals, ~ compared to a string selector now stands for an
1026 * Change encoding of `not in any group' from " " to "". This makes
1027 fleet=~ work. It also affects xdump.
1028 * Fix plane capture code to clear wing.
1029 * People now eat and starve exactly the same in sectors, ships and
1030 land units. There used to be small differences, and civilians and
1031 uw loaded on land units didn't eat at all. The starvation command
1032 has been updated accordingly.
1033 * Fix bug that makes it impossible to assault or board with land
1034 units (broken in 4.3.4).
1037 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
1038 * Don't use non-portable groff features (broken in 4.3.0).
1039 * Work around potential crash bugs in command argument access.
1040 * Plug major information leak through nation selectors (broken in
1041 4.2.21). The fix unfortunately exchanges the meaning of xdump
1042 nation and xdump country. Sorry about that.
1043 * Minimize redundancy between (mortal's) xdump nation and xdump
1045 * New nation selector rejects.
1046 * xdump nation now shows foreign relations and no longer discloses
1048 * Fix crash bug in edit.
1049 * Fix number of planes building in budget command (broken in 4.3.3).
1050 * Selectors group, fleet, wing and army are now strings, and obvious
1051 syntax like fleet#a works. xdump also shows the strings now.
1052 Units not assigned to a group currently have group string " ", but
1053 that may still change.
1054 * Don't fold conditionals to lower case, because it breaks valid
1055 conditionals like fleet#A.
1056 * Mobility cost of a plane sortie is no longer limited to current
1058 * Various formulas no longer truncate or round intermediate results.
1059 * Interdiction mission charged twice the normal mobility cost for
1061 * Fix sail not to interpret negative x-coordinates as unsail
1063 * Improved configure script.
1066 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
1067 * power c can now show powerless countries. power c * works.
1068 * Fortresses now require 5% efficiency to return fire and interdict.
1069 * Range of ship return fire and support fire no longer depends on
1071 * Fix heap smash in login command client. Remote hole!
1072 * Properly destroy nukes on collapsing bridges. Before, you could
1073 rescue them by building a new bridge or arming them on naval
1075 * Nukes are now numbered like other units:
1076 - New selector type replaces selectors number and types.
1077 - New selector plane points to plane armed with this nuke.
1078 - New selectors effic, mobil, tech, group, opx, opy, mission,
1079 radius. Provided because all units have them; values are
1080 currently not interesting.
1081 - nuke command output redesigned.
1082 - ndump output changed subtly: nukes are no longer sorted by
1083 location, nukes in the same location no longer share id, and
1084 nukes on planes are shown.
1085 - transport nuke now works like transport plane.
1086 * arm and disarm now accept the common plane syntax, not just plane
1088 * Fix arm to let you change an armed plane's air-burst/ground-burst
1090 * territory no longer re-prompts when supplied with a bad argument,
1092 * edit lets you edit stuff that is actually computed from other
1093 state, like sector's coastal flag. This makes no sense and is now
1094 deprecated. Stuff deprecated since 4.2.15 is now gone.
1097 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
1098 * Fix security units' raid at the update (broken in 4.0.0, fixed only
1099 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
1100 increase. Make sure empty units don't kill anyone.
1101 * Fix bug in player_init(), which was most likely fatal on 64 bit
1102 hosts. Broken in 4.3.0.
1103 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
1104 * The order in which sectors were visited for `*' arguments disclosed
1105 the real origin, fix. Mapping commands used to work around this
1106 bug, until 4.3.1 exposed it there as well.
1107 * Code didn't compile on some systems.
1108 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
1110 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
1111 * Fix check of game state on server startup (new in 4.3.0).
1112 * sail now accepts a destination sector.
1113 * Tend could send bogus bulletins (broken in 4.3.0).
1114 * Plug memory leaks in mission command.
1115 * Close loophole in navigate that allowed players to find all sectors
1116 that are unfriendly or inefficient harbors or bridges.
1117 * Server didn't start when default econfig was missing and user
1118 didn't supply one with -e (broken in 4.3.0).
1119 * Retreat condition 'h' (helpless) never worked, fix.
1120 * Fix retreating mine sweepers to use mobility for sweeping.
1121 * Fix retreating land units to hit mines with the same probability
1122 and to take the same damage as in normal movement. Before,
1123 hit probability was higher, and damage was lower.
1124 * Ships could retreat into sectors owned by whoever made them
1125 retreat, but not in their owner's sectors.
1126 * Fix 'm' at the movement prompt of transport and test.
1127 * Fix march and test not to apply conditionals to sectors mapped,
1128 which led to spurious error messages.
1129 * Fix break not to respect conditionals. The bug let players keep
1131 * Fix retreat code not to respect conditionals. Attackers could
1132 abuse this to suppress fleet and army retreat orders.
1133 * Fix retreat and edit to zero-terminate retreat paths.
1134 Theoretically abusable for gaining information.
1135 * Fix format string crash bugs in load, spy and bomb.
1136 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
1137 ~p before the first line of text never worked.
1138 * Fix ancient bridge building race condition that could break the
1139 test whether the player can afford the bridge.
1140 * Fix trade lot change detection in set command. Probably abusable.
1141 * The pthread code now compiles under Solaris.
1142 * navigate and march now permit any whitespace between route and
1143 optional argument for radar, lookout, sonar, not just spaces.
1144 * Fix canal navigation (was broken in 4.3.0).
1147 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
1148 * version no longer pretends option SHIPNAMES still exists.
1149 * Remove files auth and ban. They could be used to restrict client
1150 address and user. Restricting user is useless, because players can
1151 send whatever they want. Banning IPs is better done with a packet
1152 filter. That leaves restricting deity IPs. Provide new econfig
1153 key privip for that. Apply it to session kill as well as login.
1154 * xdump escapes GUINEA_PIGS status:
1155 - xdump is now enabled unconditionally.
1156 - xdump sect now dumps selector coastal, because it can't be
1157 reliably computed from other xdump information.
1158 - New xdump realm and country. Realm information is now stored in
1159 a separate file, with appropriate selectors.
1160 - Reviewed for completeness and information leaks. See info xdump
1161 for remaining issues. New treaty selector uid, nat selectors
1162 relations, contacts. Removed useless selectors: news and lost
1164 - Command syntax changed.
1165 - xdump opt is no more, option information is now in xdump ver.
1166 - xdump can now dump meta-data.
1167 - Header and footer changed to be more compact. You now need
1168 meta-data to identify fields.
1170 - Documentation in doc/xdump.
1171 * New econfig key builtindir.
1172 * New econfig key custom_tables lets you customize configuration
1173 tables without recompiling. Customizing tables other than unit
1174 tables is not recommended for now. See doc/econfig for
1176 * Check configuration and game state are sane on server startup.
1177 * Remove option NONUKES and NEUTRON. Deities can load a suitable
1178 nuke table to get the same effect.
1179 * Remove option DRNUKE. Use econfig key drnuke_const to control
1180 whether nukes need research.
1181 * Disqualify land units from performing missions while loaded on
1183 * Fix dump for strings without terminating zero.
1184 * Fix login command option not to send an extra prompt.
1185 * zdone now displays information about demand update vetoing.
1186 * The Windows port now requires Winsock version 2.
1187 * Remove econfig key powe_cost.
1188 * version report now shows all the configurable settings of interest
1190 * carg and lcarg now display people as well.
1191 * ldump now dumps civ and uw as well.
1192 * Fix dangling pointer dereference in dogfighting code.
1193 * Tell sector owner when partisans take over. But don't disclose che
1195 * emp_server, files, fairland now support options -h and -v.
1196 * Simplify baroque version numbering to a single version number.
1197 This affects output of version.
1198 * New show item and show news.
1199 * New build process:
1200 - Follow the usual steps: configure; make; make install. The
1201 latter is optional. The only file deities still have to edit is
1203 - Use GNU Autoconf for system configuration.
1204 - Use GNU Make for portability and features.
1205 - Support separate build trees.
1206 - Remake out-of-date dependencies automatically.
1207 - Remake out-of-date info files automatically.
1208 - Flatten info directory.
1209 - Formatted info files are no longer distributed in source tarball.
1210 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
1211 low-level options doesn't seem to be worth the effort, as
1212 UCONTEXT should be pretty portable.
1213 * Fix use of freed memory in sail.
1214 * sail could let large ships enter big cities.
1215 * Fix reject and accept not to require contact.
1216 * Fix sharebmap and telegram to prompt for a missing first argument.
1217 * Fix report to align column research correctly for deities.
1218 * When the optional newspaper argument doesn't work because HIDDEN is
1219 enabled, complain instead of ignoring it silently.
1220 * When BLITZ is enabled, fairland no longer permutes country numbers
1221 in newcap_script so that start islands are ordered from top left to
1223 * Minimize output format differences between options:
1224 - census shows column fall regardless of FALLOUT.
1225 - show nuke now shows column res regardless of DRNUKE.
1226 - report no longer suppress column status when HIDDEN is enabled.
1227 HIDDEN limits status information like for the country command.
1228 - relations column width differed depending on option SLOW_WAR.
1229 Always use the wider format.
1230 * Fix a bug in edit that suppressed the player notification telex on
1231 military reserve change.
1232 * Fix command dispatch not to let deities use commands that are
1233 declared not to be available to them. The only command affected is
1235 * Fix the list command for visitor.
1236 * econfig key m_m_p_d no longer applies to deities.
1237 * Fix the origin command for country #0. Allow moving origin to
1238 another country's origin. Allow deities to reset origin to
1239 absolute 0,0. This turns origin into a superset of the offset
1240 command. Remove offset command.
1241 * Fix a bug that caused unpredictable flak damage when it should have
1242 been maximum damage (was broken in 4.2.19).
1243 * Don't store initial capital location, remove the associated nat
1244 selectors xstart, ystart.
1245 * Fix production command to consider resource depletion.
1246 * Fix justification of coordinate output in cutoff and mission.
1247 * Option UPDATESCHED is no longer optional. Disabling it didn't
1250 * Turn options into ordinary econfig keys.
1251 * New econfig key start_cash.
1252 * BTU regeneration now depends on the capital's work percentage.
1253 * nation now supports an optional argument that lets deities ask for
1254 somebody else's nation report.
1255 * Fix nation to display SANCTUARY instead of VISITOR for countries in
1257 * Fix capital to let you use a regained sacked capital without
1258 activating another one in between.
1259 * Don't move capital when it is sacked.
1260 * New ship capability canal, replacing obscure formula based on build
1262 * You now need a capital to request a demand update.
1263 * power now ignores landspies.
1264 * Fix LWP stack checking.
1265 * Clean up LWP, drop dead machine-specific code, fix portability bugs
1267 * census now shows the old owner instead of `*'. dump is unchanged
1268 to avoid breaking clients.
1269 * peek no longer prints the old owner.
1270 * When a bombed land unit retreated, collateral damage was applied to
1272 * paradrop, drop and fly can no longer abandon the base sector.
1273 * Tending foreign ships now sends a bulletin to the owner.
1274 * Fix bug that permitted login for inactive countries, including ""
1275 * Fix tend for spies.
1276 * Change launch to fire all missiles selected at the same target.
1277 Previously, it prompted for a new target after each missile.
1278 * add, consider, build, launch and fire no longer re-prompt when
1279 supplied with a bad argument, they just fail. Consequently, the
1280 build command no longer lets you list types you can build. It
1281 points to the show command instead.
1282 * Fix add not to truncate country number.
1283 * Fix selector coastal to be accurate at all times.
1284 * Fix obscure bug in fairland: the sector added last to an island
1285 wasn't considered coastal. Affected resource computation.
1286 * Fix sector wiping in add command.
1287 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
1288 ways. Custom configuration tables should become a serviceable
1289 replacement eventually.
1290 * Client no longer freezes on long lines of server output.
1291 * Fix uninitialized signal mask bugs.
1292 * Fix Windows service code's treatment of -e.
1293 * Sub interdiction disclosed sub owner through news' actor selector.
1294 * country reports on all countries, but carefully limits information
1295 disclosed to mortals. Output format changed.
1296 * Market no longer forces sellers to grant loans.
1297 * Fix potential crash bug in set command. Friendlier prompt and
1299 * Substantial code cleanup and portability fixes.
1300 * Extend empfile abstraction to cover game configuration.
1301 * Overhaul of game state storage.
1302 * The above includes major contributions from Ron Koenderink. Many
1305 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
1306 * Make version pretend option SHIPNAMES still exists, for the benefit
1307 of clients that still depend on it.
1308 * The change to conv in 4.2.22 could crash or compute incorrect
1310 * Info updates missing in 4.2.22.
1311 * A few code cleanups.
1313 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
1314 * Log player login, logout and session kill.
1315 * Close loophole in assembly point rules that allowed players to find
1316 all unowned sectors. The assembly point must now be owned by you
1317 or an ally, or you or an ally must have a ship there.
1318 * Don't let embarked land units fire flak.
1319 * Fix display of the last connection's host when the host name was
1321 * Fix change command to accept full length representative (password),
1322 currently 19 characters. It used to chop off after eight
1324 * Non-recon missions no longer establish contact to owners of
1325 overflown sectors, because those missions do not identify the
1326 owner. This matches info Hidden.
1327 * The following events now establish contact:
1329 - Sighting a ship when toggle coastwatch is off
1330 - Spotting overflying planes
1331 - satellite spotting land units
1332 - lookout and llookout spotting ships, planes and land units
1333 - Any relations change
1334 * The country command's `temporary' state of disorder ended after
1336 * Telegram notifications could get lost in exotic circumstances,
1337 e.g. while a second client attempted to connect. Abusable.
1338 * Remove option SNEAK_ATTACK.
1339 * Fix lboard not to let you board dead land units.
1340 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
1342 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
1344 * Fix fly to let the player abort the command at the last prompt.
1345 * Client no longer reads execute scripts in binary mode under
1347 * New econfig key listen_address.
1348 * econfig key port can now be a service name. Service empire no
1349 longer takes precedence over econfig.
1350 * Client falls back to compiled-in host only if environment doesn't
1351 supply one, not if it can't be resolved. Same for port.
1352 * Oil derrick could extract slightly more oil than was in the ground.
1353 * test command checked start sector for space and some other things
1354 instead of end sector.
1355 * convert now silently limits conversions to avoid exceeding maximum
1357 * shoot no longer limits you to 999 victims.
1358 * 4.2.19 broke pin-bombing commodities on some platforms.
1359 * Don't block on output while update is pending. This is required to
1360 ensure the update can abort commands.
1361 * Commands submitted while the update is waiting for commands to
1363 * The force command no longer waits for the specified time. It
1364 starts a scheduling thread instead, just like shutdown.
1365 * Correct grammar and punctuation in output of version.
1366 * Option SHIPNAMES is no longer optional.
1367 * Fix output of qorder and sorder for ships with sail path.
1368 * Don't change capital to agribusiness on retake. From Pat Loney.
1369 * bdes prompt for new designation was messed up for empty bmaps.
1370 * Client now supports pipes under Windows.
1371 * Care for subtle Windows socket incompatibilities.
1372 * Fix strength command not to lie about units reacting into
1374 * strength now yields the processor periodically, to keep the game
1376 * Schedule commands more fairly. Previously, a sufficiently fast
1377 player could starve out the others.
1378 * launch assumed plane maximum mobility 127 for calculating when
1379 satellites will be ready to use.
1380 * Drop support for for DCE threads.
1381 * Drop support for pthread implementations lacking pthread_kill().
1382 This includes ancient versions of OS X.
1384 * Minor info file fixes.
1385 * The above includes major contributions from Ron Koenderink. Many
1388 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
1389 * Don't let threads block on output to another player thread's
1390 socket. Such blocking violates basic design assumptions and can
1391 cause all kinds of grief. In particular, it causes player session
1392 hangs under Windows with 4.2.20. Broken since the introduction of
1393 flash and asynchronous telegram notification many years ago.
1394 * Threads sleeping until a specified time could return early under
1395 Windows. This could cause double-updates.
1396 * Fix fallout damage (was broken in 4.2.19).
1397 * Fix show sector s (was broken in 4.2.19).
1398 * Fix deliver not to deliver friendly civilians into occupied
1400 * Fix mil duplication in board (was broken in 4.2.14).
1401 * Fix stack smash in lrange, shoot and execute. Remote holes, and
1402 the last one doesn't even require authentication.
1403 * Fix crash bug in emp_config parsing.
1404 * Fix buffer overruns in turn and shutdown.
1405 * Fix second argument of shutdown.
1406 * tele and turn now abort on EOF.
1407 * Fix display of MOTD and game down message of maximum size.
1408 * Correctly support telnet line termination on input. Previously,
1409 carriage returns could slip into ship names and such.
1410 * Fix flash not to lie about recipients that are just logging in.
1411 * Remove obscure login command list.
1412 * Convert client from obsolete termcap to terminfo, and clean up
1414 * New fairland option -h to print usage information. Improved
1415 command line syntax diagnostics. Exit unsuccessfully on unknown
1417 * fleet and army now copy retreat orders of the fleet's or army's
1418 first member with group retreat orders in the same sector.
1419 Previously, they used the retreat orders of the first fleet or army
1420 member, which is less than useful, and failed to take ownership
1421 into account, which is an abusable bug.
1423 * Fix xdump not to disclose other countries' losses.
1424 * Fix exit status of files program when it can't create files.
1425 * Support UTF-8 encoded Unicode in human-human communications. This
1426 affects MOTD, game down message, telexes, announcements and flash
1427 messages. See new doc/unicode for technical details.
1428 * New login command `options' for client/server option negotiation.
1429 See new doc/clients-howto for technical details. The only option
1431 * emp_client -u now requests UTF-8. This requires a terminal that
1433 * Fix news for land unit defensive support.
1434 * Properly mark sea mines hit by retreating ships. Unmark mines
1436 * Fix diagnostics for unknown selector names in conditionals (was
1438 * Fix selector name clashes: rename ship selector mobquota to mquota,
1439 land selector for reaction range limit from rad to rmax.
1440 * Fix Windows services for relative file names on command line or in
1441 econfig (was broken in 4.2.20).
1442 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
1443 are now float. This gives deities finer control over maximum
1445 * Fix production command for sectors with 60% efficiency.
1446 * Improve syntax of read for deities.
1448 * Some info topic names differed only in case, which loses on
1449 case-insensitive file systems, and is a bad user interface even
1450 when it works. Change those names. Rename deity command hidden to
1451 peek because its info topic clashed with that of option HIDDEN.
1452 * Thanks to Doug Wescott sheep are finally covered properly in info.
1453 * Documentation fixes.
1454 * Much of the above was contributed by Ron Koenderink. Many thanks!
1456 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
1457 * When units in different sectors marched, only units in the sector
1458 with the highest-numbered unit were interdicted. A marching
1459 non-spy made all marching spies visible to interdiction regardless
1461 * Fix crash when interdiction sinks second ship in a sector. Broken
1463 * Fix an ancient bug in simulation of level production that clobbered
1464 stack and could lead to low predictions, typically zero, which
1465 screwed up budget. The bug had no effect until 4.2.19.
1466 * When a sector revolts, and there wasn't enough space to liberate
1467 all uw, the number of remaining uw got the wrong sign. Broken in
1469 * Log and abort when LWP stack check detects stack smash. Server
1470 option -s no longer implies -p.
1471 * The native Windows build now supports -p and -s.
1472 * The native Windows build now properly deals with ^C when running in
1473 the foreground. It no longer prompts for a quit command on the
1475 * The meaning of server option -D in presence of -e is unclear.
1476 Other programs only support -e. Remove option -D. Use -e
1477 DIR/econfig instead of -D DIR.
1478 * New server option -v shows version information.
1479 * Fix the server's exit status with -h. Broken in 4.2.19.
1480 * The linux-pthreads build failed to shut down on signals.
1481 * Fix threading bugs in the native Windows build that made shutdown
1482 unsafe and screwed up update aborting commands.
1483 * New econfig key pre_update_hook to allow automatic, safe backup
1484 right before the update. See scripts/backup for an example.
1485 * The server now prints log messages to stderr as well when running
1487 * Fix potential buffer overflows in logerror() and lwpStatus().
1488 * Server now requires POSIX signals. It no longer catches SIGUSR1.
1489 * Remove support for ancient versions of HP-UX.
1490 * Fix seeding of PRNG broken in 4.2.19.
1491 * Don't reseed the PRNG in commands, it hurts randomness and could be
1492 abused by crafty players.
1493 * The server now makes the data directory its working directory.
1494 This also gets rid of a bug that changed the file name of the
1495 sector, power, nation and lostitems file unless econfig could not
1497 * The server now writes a pid file. Thanks to Daniel O'Connor.
1498 * More user friendly server startup: more errors are detected while
1499 the server still runs in the foreground, which makes it possible to
1500 complain to stderr and to exit unsuccessfully.
1501 * Early log messages went to the log file in the default data
1502 directory, even though econfig specifies another data directory.
1503 * Specifying an econfig file on the command line that can't be read
1505 * Errors in econfig are now fatal.
1506 * The server now refuses to start when it can't open data files.
1507 * News are now sorted and expire sanely.
1508 * Conditionals can now compare strings as well.
1509 * Corrupted down and motd files could cause buffer overflows.
1510 * Fix recon to let player abort at the flight path prompt.
1511 * power no longer rounds worldwide numbers for deities.
1512 * power command failed to recognize deities with non-zero country
1514 * Change output of production command so that columns are aligned
1515 even for large values. Replace column wkfc by more useful column
1517 * neweff and production miscalculated work when mil exceeded
1519 * neweff miscalculated work when the population limit exceeded 999.
1520 * Fix capping of avail when a big city is torn down.
1521 * Fix a bug in fire that allowed players to find all submarine uids.
1522 * Maximum sector population is no longer hardcoded, and now covered
1523 by xdump. Option RES_POP now affects mountains and plains as
1524 well. From Ray Hyatt.
1525 * Fix fina and news not to ignore errors in conditions.
1526 * The native Windows build now requires Windows Sockets 2.
1527 * The native Windows build now supports multiple instances of the
1528 service. The ability to supply additional startup parameters to
1529 the service has been removed.
1530 * Implement fairland command line parsing under Windows.
1531 * Improved fairland and emp_server usage message.
1533 * Minor info file and documentation fixes.
1534 * Much of the above was contributed by Ron Koenderink. Many thanks!
1536 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
1537 * Fix order not to unload into full sectors.
1538 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
1540 * Fix distribute not to conjure up a civilian when importing
1541 civilians from a dist center that doesn't have any.
1542 * Fix flak to resupply no more shells than actually needed.
1543 * Fix rounding error in shoot that could result in more people shot
1544 than actually there.
1545 * Fix info and apro error handling. In particular, do not leak
1546 potentially sensitive information on the server to players.
1547 * info no longer shows a random matching page when the topic argument
1548 is ambiguous. Instead, it lists all matching topics.
1549 * Embarked land units and overflying planes no longer spot each
1551 * Fix show command to show only sectors that players can designate
1552 (was broken in 4.2.18).
1553 * Fix a rounding error in production command column `max'.
1554 * Fix production command for overpopulated mountains and plains.
1555 * Fix tradeship ally cut to match documentation.
1556 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
1557 * Fix a bug in aerial sonar where ships could mask submarines with
1558 the same number modulo 256.
1559 * Don't allow bombing of subs that were not detected.
1560 * MOTD and the game down message are now entirely separate: use `turn
1561 motd' for the MOTD, and `turn on' and `turn off' for the game down
1562 message. `turn on' no longer lets you edit the MOTD.
1563 * Remove option NUKEFAILDETONATE.
1564 * Option ORBIT is no longer optional.
1565 * New option GUINEA_PIGS to control experimental stuff not ready for
1566 prime time. If your deity enables this in a serious game, run!
1567 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
1568 * New ship and land selectors rflags, rpath.
1569 * New ship selectors for order: xstart. xend, ystart, yend,
1570 cargostart, cargend, amtstart, amtend
1571 * New ship selectors for sail: mobquota, path, follow.
1572 * New news selector uid.
1573 * Implement command line parsing under Windows where it was missing.
1574 * emp_server and and files print a usage message on command line
1576 * Fix how emp_server exits after being panicked by a signal. It can
1577 now dump core when this happens.
1578 * Fix bug in client that could crash it when a line of input starts
1580 * Client now gets user name from environment variable LOGNAME if set,
1582 * The native Windows build can now run as a service.
1583 * Redirecting client input now works under Windows.
1585 * Don't confuse work with loyalty in info Citizens.
1586 * Minor info file and manual page fixes.
1587 * Much of the above was contributed by Ron Koenderink and Marc
1588 Olzheim. Many thanks!
1590 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
1591 * Fix info to accept abbreviated arguments under Windows. From Ron
1593 * Buying planes or land units loaded on something didn't work when
1594 that something moved.
1595 * Fix a bug that could produce update cascades with update policy
1597 * Fix delivery and distribution to grant packing bonus only to
1598 efficient sectors, just like move. Previously, delivery ignored
1599 efficiency, and distribution behaved as if it were an efficient
1600 sector without special bonuses.
1601 * New sector selectors loyal, access; ship selectors radius, access,
1602 xbuilt, ybuilt, builder, name; plane selectors radius, access,
1603 theta; land unit selectors radius, react, nland, access; lost
1605 * Fix sector selectors che, che_target; plane selectors att, def;
1606 nuke selector types; treaty selector exp; news selector time;
1607 commodity selectors type, xbuy, ybuy.
1608 * Option PLANENAMES is no longer optional.
1609 * Ensure config parameter variables and their description in
1610 configkeys[] are consistent. Inconsistencies there caused bugs in
1611 the past. From Marc Olzheim.
1612 * Complain if econfig file can't be read.
1613 * Better messages for errors in econfig file.
1614 * Remove unused econfig keys hard_tech and last_demand_update.
1615 * New econfig key news_keep_days to configure news expiry.
1616 * New econfig key anno_keep_days to configure announcement expiry.
1617 * Fix announcement expiry. It leaked file descriptors and memory,
1618 and could corrupt the anno file. From Ron Koenderink.
1619 * New command xdump: experimental extended dump. Disabled for now.
1620 * Bankers no longer round down debts, and they collect interest for
1621 the time debtors are idling at sub-prompts.
1622 * Loan interest calculation was broken at the due date and after a
1623 last payment made at the due date. With luck, debtors could abuse
1624 this to repay loans cheap (they couldn't gain cash, though), sharks
1625 to purchase loans cheap, and creditors to collect excessively.
1626 * Fix major bug in transport that allowed two cooperating countries
1628 * Don't report interdiction damage twice when transporting planes.
1629 * Fix message for attempting to transport a plane in a sector not
1630 owned by the player.
1631 * Fix confusing diagnostics when refusing to improve defense because
1632 option DEFENSE_INFRA is off.
1633 * Simplify confusing code in budget.
1634 * Fix spacing in output of budget and show.
1635 * Change one-way plane sorties to match ordinary sorties: offer
1636 carriers regardless of the sector they're in, require carriers to
1639 * Don't print owner of incoming missile twice when intercepting it.
1640 * Simplify constituent storage in product characteristics.
1641 * Replace remaining `variables' leftovers; mainly in unit
1643 * Remove leading spaces in deity unit dumps.
1644 * Replace inappropriate uses of compile time constant ETUS by 60.
1645 Deities don't change ETUS, they change etu_per_update by editing
1646 econfig. This nonsense dates back at least to chainsaw 3.31.
1647 * Change ship production (fishing and drilling for oil) to match
1648 sector production. Ship efficiency and tech are now relevant, and
1649 all people on board work. From Ron Koenderink.
1651 * Minor info file fixes.
1653 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
1654 * Fix seeding of PRNG under Windows. The bug made updates occur at
1655 a predictable time in the update window. From Ron Koenderink.
1656 * Close major loophole in drop that allowed players to determine
1657 whether an arbitrary sector is sea, allied land, or other land.
1658 * fly could fly civilians into occupied sectors. For consistency
1659 with other means to move around stuff, this is no longer possible.
1660 * Don't allow flying to a carrier that doesn't have space for the
1661 planes. Previously, planes that did this were teleported home,
1662 which could be abused.
1663 * Close loophole in bomb that allowed players to find all
1665 * Fix move and explore not to crash when moving civilians to a sector
1666 without civilians, and interdiction destroys them all. Found and
1667 debugged by Jeff Cotter.
1668 * Fix printing of messages entered with turn command. '%' characters
1669 could cause havoc, even crashes.
1670 * Use sector's actual maximum population to compute chance of plague
1671 outbreak. Previously, code used 9999 for big cities and 999 for
1672 other sectors, and info Plague said 999. This makes all crowded
1673 sectors equally vulnerable, even mountains, plains, and inefficient
1675 * Oil derricks no longer drill and deplete more oil than they can
1676 hold. From Ron Koenderink.
1677 * Version 4.2.15's coordinate and list parsing fixes reject trailing
1678 junk. That's too strict. Silently ignore trailing junk as long as
1679 it starts with whitespace.
1680 * Version 4.2.15's selector rewrite broke some type literals,
1681 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
1682 type literals to selectors.
1683 * Nightly build patches game to get repeatable PRNG results. From
1686 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
1687 * Previous version broke sector production when part of the work is
1688 used for sector construction. Fix courtesy Jeff Cotter.
1689 * Add rudimentary tests to nightly build. From Marc Olzheim.
1691 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
1692 * test command no longer asks whether to abandon the sector.
1693 * explore command could generate a bogus `lost' record when it
1694 regains an abandoned start sector.
1695 * edit command now properly updates stats when editing tech level of
1696 ships, planes or land units. A few of these stats can be edited
1697 separately, which doesn't make much sense, and is now deprecated.
1698 * edit command no longer accepts efficiency values that would destroy
1699 the edited unit. Deities can still delete units by setting the
1701 * upgrade command used to charge an amount of avail that didn't match
1702 info upgrade. Neither the implemented nor the documented amount
1703 made much sense. Change it to 15% of the full build cost. Rewrite
1705 * Commands upgrade and build could be off by one when reporting
1707 * upgrade command reported rounded cost but charged unrounded
1708 cost. Round cost of upgrade down to match behavior of build.
1709 * Upgrading planes now preserves range when it is less than the
1710 maximum range. It used to set it to the new maximum range.
1711 * show bridge and show tower no longer claim bridge building requires
1712 `workers' (whatever that is), since it doesn't.
1713 * Replace option ROLLOVER_AVAIL by econfig parameter
1714 rollover_avail_max, which is the maximum amount of avail that rolls
1715 over. Previously, avail was limited after rollover, and even when
1716 ROLLOVER_AVAIL was off. Fix that.
1717 * Ships weren't always charged mobility for firing with option
1719 * Fix shell use of return torpedoes.
1720 * designate no longer complains twice about deity only designations.
1721 * Ensure designate zaps efficiency only when sector type really
1723 * Fix strength to always report mines to deities.
1724 * Remove option SHIP_DECAY.
1725 * Fix bug in sonar that could crash or yield unpredictable results
1726 near the true origin.
1727 * Fix buffer overflow in flash and wall.
1728 * Fix wall not to strip out first word of message.
1729 * Change market and order to use item types instead of mnemo
1730 characters internally.
1731 * Market now reports sales with full item names instead of single
1733 * buy now requires first argument to be an item name, as documented.
1734 * production command handled production backlog incorrectly, failed
1735 to limit production for production efficiency greater than one,
1736 e.g. agribusiness, and incorrectly limited raw material
1737 consumption. Also fix a rounding error. With help from Ron
1739 * Sector work was accidentally truncated to even.
1740 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
1741 don't divide SHRT_MAX+1.
1742 * Properly diagnose over-long unit lists.
1743 * Rewrite selector code. Old code let players smash the stack by
1744 supplying too many conditions. New code properly rejects ambiguous
1745 abbreviations and prefers exact matches. Selectors with names that
1746 collide with types, like land units' rad and spy, now work.
1747 Selectors with non-integral values, like land units' att, now work.
1748 * survey used to display hundreds for everything but variables. Now
1749 it displays hundreds only for values that can be large.
1750 * Rewrite info survey. Document ability to survey properties other
1751 than items and resources.
1752 * Rewrite info build, since it was inaccurate and poorly structured.
1753 * Fix info fire on required military. From Marc Olzheim.
1754 * New fairland argument -R to set the PRNG seed. Print the seed.
1755 This allows you to recreate the same world again.
1756 * New facilities to deal with internal errors. These crash when the
1757 server is started with -d, which is appropriate for debugging, and
1758 potentially disastrous for running a real game.
1759 * Automated nightly builds.
1762 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
1763 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
1764 * Gripe about unknown options in econfig.
1765 * Remove option GRAB_THINGS.
1766 * Utility program files takes new option -f.
1767 * Remove utility programs land, ore and perfect, which don't compile
1768 since 4.2.0 (Oct '98).
1769 * fairland no longer warns when it added resources, but when it
1771 * Fallout code could claim destruction of more items than actually
1773 * Fix recursive resupply (resupply from supply land unit triggering a
1774 resupply of the land unit) when just testing for how much can be
1775 resupplied. The bug could have led to insufficient resupply.
1776 * Fix recursive resupply not to consume all fuel in supply units. No
1777 supply units consuming fuel exist in the stock game.
1778 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
1779 Distribution threshold were previously limited to 10000, and
1780 delivery thresholds to 65528.
1781 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
1782 used to limit to 9990. Market transactions and commands explore,
1783 move, drop and fly to 32767. Limiting in autonav code (order
1784 command) didn't work. Item delivery used to stop at 9990,
1785 distribution at 9999. Food growing and sector production used to
1786 stop at 9999. Grind, assault lunchboxes, demobilization, mine
1787 sweeping and che liberating uw could theoretically attempt to
1788 increase items beyond 65535, which would have been ignored
1789 (destroying the increase).
1790 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
1791 fallout increases behaved inconsistently. Increases beyond 65535
1792 could get ignored, or fallout could saturate at 9999, or it could
1793 overflow at 65536 (that would take quite some nuking, though).
1794 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
1795 operation that would have gone beyond 65535 was ignored.
1796 * Fix `are we loading or unloading' tests for load, unload, lload and
1798 * Fix editing of land unit attack and defense values. Implement
1799 editing of ship defense values. Contributed by Ron Koenderink.
1800 * edit now edits che number and target separately.
1801 * Fix edit to properly extend unit files. Contributed by Ron
1803 * Major internal reorganisation: Sectors need space for items,
1804 deliveries and distribution thresholds. To save space, the
1805 ancients invented `variables': a collection of key-value pairs,
1806 missing means zero value, space for `enough' keys. This
1807 complicates the code, as assigning to a `variable' can fail for
1808 lack of space. Over time, `enough' increased, and for quite some
1809 time now `variables' have been *wasting* space. Replace them,
1810 except in unit characteristics, where they are read-only, and will
1811 be replaced later. This also removes misfeatures like plague
1812 outbreaks silently deleting deliveries.
1813 * Remove disabled commands dissolve and mult. Remove configuration
1814 parameters minmult and maxmult.
1815 * trade command indexed an array out of bounds when attempting to
1816 display the plague as commodity. Fix.
1817 * New make goal interix. Contributed by Ron Koenderink.
1818 * The type selector now prefers an exact match to a partial match.
1819 ?type=sb now selects sb, not sbc, even when sbc happens to be found
1821 * Value of selector sell was always zero, remove it.
1822 * Clean up selector code.
1823 * satellite now displays all sectors owned by other players, and none
1824 else. It used to display all but sea, mountains, sanctuaries,
1825 wasteland and wilderness.
1826 * map commands now display wilderness and plains owned by other
1827 players as '?'. Radar commands now display all wilderness and
1829 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
1830 * Make client abort the current command on ^C under Windows, as
1831 everywhere else. Contributed by Ron Koenderink.
1832 * Command line parser interpreted trailing whitespace as an another
1833 (empty) argument. Ignore it instead.
1834 * Properly declare stuff in headers, include proper system headers.
1835 Remove all nested external declarations. Source code is now fully
1836 prototyped. Enable appropriate gcc warnings.
1837 * Fix several type errors. Some may have been show-stoppers on big
1838 endian machines where sizeof(long) != sizeof(int).
1839 * Remove pre-ISO C compatibility cruft (hey, it's been only fifteen
1841 * Various portability fixes. Some bugs may have been show-stoppers
1842 when sizeof(long) != sizeof(int). With help from Marc Olzheim and
1844 * Move some code to more logical places. Remove some unused code,
1845 some of which was hard to port.
1846 * The files program could print error messages to a log file in some
1847 circumstances. Make it print to stderr.
1848 * deliver can now change direction without changing the threshold.
1849 * deliver now provides appropriate context when prompting for
1851 * Login command play no longer ignores up to two arguments if there
1853 * Fix payoff (was broken in 4.2.13).
1854 * Capability fish didn't work together with capability oil.
1855 * Fix and clarify plague outbreak chance in info Plague.
1856 * Fix RES_POP maximum population in info Research.
1857 * Fix info telegram and info announce on ~ escapes.
1858 * Update info Selector to match code.
1859 * Document all undocumented unit capabilities and stats.
1860 * Document submarines' ability to carry landspies.
1861 * Fix info shoot on security units.
1862 * Various small info file fixes.
1863 * Many fixes in the troff macro package for info files.
1864 * Many fixes for translating info files to HTML.
1865 * Many info file markup fixes.
1867 Changes to Empire 4.2.13 - Fri Feb 13 22:12:36 UTC 2004
1868 * Source code reindented and cleaned up somewhat.
1869 * Various small info file fixes.
1870 * Fixed change requiring 254 BTUs even when not charging any
1872 * Fixed tactical non-marine missile crash.
1873 * Fixed spy unit detection chance for eff<100.
1874 * Fixed output of sorder.
1875 * `edit' can now work non-interactively. Contributed by Ron
1877 * Fixed and extended edit for sectors.
1878 * Fixed use of errno.
1879 * Minor security fix: doconfig now writes example auth entry as
1881 * Fixed reading of country name and password in client for Windows.
1882 * Replace use of some obsolete non-portable library functions by
1883 portable equivalents.
1884 * designate now warns about redesignated capital only when it
1885 succeeds in redesignating the capital.
1886 * attack could be off by one when reporting required unit mobility.
1887 * Fixed command matching. Unique prefixes were not always
1888 recognized, and junk suffixes were ignored.
1889 * Removed bestdistpath. bestpath yields the same results.
1890 * Renamed lstats to lstat for consistency and to match info page.
1891 * Fixed non-portable fd_set * arguments of select().
1892 * New `map' flag `h' to highlight own sectors. Contributed by Marc
1894 * Fixed `sabo' reporting damage to player in deity coordinates.
1895 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
1896 * Fix Windows server shutdown on reading "quit" from stdin.
1897 * Land units now fortify automatically when mobility plus growth
1898 exceeds the maximum. With code from Marc Olzheim.
1899 * Wandering che are less predictable.
1900 * Land units no longer regenerate mobility faster while it is
1902 * Fixed emp_client -k.
1903 * No longer allow pirates to ferret out where a ship was built.
1904 * Fixed map commands to reject bmap flags `t' and `r' instead of
1906 * Fixed lmine shell resupply.
1907 * News no longer call all sub-launched missiles nuclear.
1908 * Incoming missiles are now reported with coordinates.
1909 * Removed some code that served no purpose except crashing on
1911 * Fixed Mac OSX and AIX build problems.
1912 * Don't resolve player IP addresses for now, because it can crash
1913 with certain versions of GNU libc.
1914 * Fixed recording of lost nukes.
1916 Changes to Empire 4.2.12 - Mon Aug 18 16:54:21 MDT 2003
1917 * Corrected contact information for Wolfpack.
1918 * Sector isn't abandoned until move or explore is complete.
1919 * Fixed multiple cases where return value of getstarg() was
1920 used without being checked which crashed the server.
1921 * Used stdarg.h instead of varargs.h.
1922 * Call only_subs and save result before mission frees attacker
1923 list. Call with free list could cause server crash.
1924 * Fixed spy sat map for units on opposite side of world wrap.
1925 * Don't sleep in main thread when called from signal handler.
1926 * Fixed error checking in pthreads.
1927 * Properly detach pthreads.
1928 * Pass unlocked mutex to pthread_mutex_unlock.
1929 * Cope with interrupted sleep in pthread empth_sleep to prevent
1931 * Added server configurable update window.
1932 * Initialized variables passed to setsockopt in accept.c.
1933 * Fixed bug where sharing bmap with uncontacted country crashes
1936 Changes to Empire 4.2.11 - Sun Sep 1 09:54:59 MDT 2002
1937 * Added compile option for the Mac OSX architecture.
1938 * Fixed bug in cargo where unit array was indexed by shp_maxno
1939 instead of lnd_maxno.
1940 * Fixed bug in reject where aborting the command crashes the
1942 * Can't buy land units into enemy headquarters.
1943 * Added sabotage command and commando unit.
1944 * Spies moving by themselves will not trigger interdiction.
1945 * Fixed error in map distance calculation that caused errant
1947 * Ships going under -127 mobility will be set to -127 mob and
1948 not roll over to positive mobility.
1949 * Corrected plane cost in info Maintenance.
1950 * Changed error message for loans rejected for being too big.
1951 * Land units will take casualty damage proportional to their
1952 ability to carry mil.
1953 * Fixed bug where "route i *" crashes server.
1954 * Cannot upgrade planes in orbit.
1955 * Fixed bug in declare with deity aborting command at last
1956 prompt crashes the server.
1957 * Coastwatch notify works with NO_FORT_FIRE option.
1958 * Thread that kills idle connection will charge player for
1959 minutes the player was logged on.
1960 * Removed separate sendeof at end of execute from emp_client
1961 that logged players off on certain platforms.
1962 * Updated player idle counter during read prompt so players
1963 wouldn't be kicked off during long flashes or writing telegrams.
1964 * LOSE_CONTACT will work as advertised.
1965 * Allied units marching through 0 mobility conquered sectors
1966 are charged at least LND_MINMOBCOST.
1968 Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001
1969 * Assault can reinforce own sector when SLOW_WAR is enabled.
1970 * emp_client no longer converts lines into tags but still verifies executes,
1971 pipes, and file redirect match players input.
1972 * Added pboard command to capture enemy planes in your territory.
1973 * Declaring war when at Sitzkrieg won't return relations to Mobilizing.
1974 * Declaring war won't charge money if you're already Mobilizing.
1975 * Added multiple territory fields.
1976 * "show nuke build" displays the proper avail.
1977 * retreating land units will only retreat to sectors owned by the player
1979 * added hard cap of "250 + easy" to limit_level.
1980 * education p.e. calculation divides edu constant by etu per update.
1981 * Added patch for Linux for the PowerPC.
1983 Changes to Empire 4.2.9 - Sun Jan 7 15:49:13 PST 2001
1984 * Fixed data corruption when bogus target gets fired upon.
1985 * Increased size of ancillary stacks to prevent stack overflow.
1986 * Changed all references to empire.cx.
1987 * Ships, planes, and land units lost to lack of maintenance will now be
1989 * No longer allowed to sack deity's capital.
1990 * Accuracy calculation in land unit support was backwards.
1991 * Corrected formula for likelihood of plague in info Plague.
1992 * Fixed files to correctly size map and bmap files from econfig file.
1993 * No longer allowed to add country 0. It corrupts deity country.
1995 Changes to Empire 4.2.8 - Mon Oct 9 17:35:35 MDT 2000
1996 * Fixed range in radar.t and Sector-types.t. Maximum range at infinite
1998 * Changed so that player can't drop civilians into occupied sectors.
1999 * Fixed bug that crashes update if etus/update is less than 8.
2000 * Fixed sometimes not reporting overflights
2001 * Fixing flak for units/ships to be in all sectors as they should be
2002 * Updated order of firing flak in Flak.t.
2003 * Fixed 80% efficient planes on ships must be maintained.
2004 * Fixed initial MOB_ACCESS check thread sleep time was set by an uninitialized
2006 * Removed "TEMPORARILY DISABLED" message from mission command for escort
2007 missions. Escort missions have been re-enabled since 4.0.15.
2008 * Using sonar from the navigate command will print the sonar map.
2009 * Eliminated annoying error messages when using navigate with conditionals.
2010 * Fixed Technology.t to correctly add 1 before taking the logarithm.
2011 * Fixed bug that allowed players to steal opponents maps.
2012 * Put time limit for bidding on market and trade in econfig file.
2013 * Moved hours file information into econfig file.
2014 * Added comments on setting update policy in econfig file.
2015 * Added logging of cases where write extends data file by more than one id.
2016 * Option MARKET is turned off by default.
2018 Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
2019 * Added new NF_SACKED flag to indicate when a country has had it's
2020 capital sacked. This flag is only cleared when the country actively
2021 redesignates it's capital using the "capital" command, and changed
2022 capital.t to reflect this (no more re-sacking after an update if the
2023 country doesn't reset and repeating until they are out of cash.)
2024 * Added land unit to edit command for planes.
2025 * Added nuketype to edit command for planes.
2026 * Changed so that if the leader of a group of units is a train, the
2027 railways are used for bestpath instead of roadways.
2028 * Changed mission command to also print reaction radius of reserve
2029 missions when set for land units.
2030 * Changed Flak.t to reflect guns having to be loaded onto a land unit
2032 * Changed so that visitor countries cannot change their name or password.
2033 * Changed so that you cannot upgrade deity planes, ships or units.
2034 * Changed so that you know where missions are flown from.
2035 * Changed so that the airport owner you fly a mission from is informed.
2036 * Changed so that preperations for takeoff are reported to the owner of
2037 the sector, ship or unit a plane is taking off from if it is not owned
2038 by the owner of the plane.
2039 * Changed so that when a sector reverts during a guerrilla revolt, the
2040 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
2041 you would always get at least an updates worth of mobility. With
2042 MOB_ACCESS, sectors that reverted during the update were useless, since you
2043 got no mobility for a long time. This fixes that problem, and makes che
2044 more useful as well.
2045 * Changed so that air defense missions don't always send up every plane in the
2046 area, but instead always send up at most two times the number of incoming
2047 planes (for each interdicting country.) This helps to stop 1 plane from
2048 stripping the mobility from 25 air defense planes all at once, but doesn't
2049 limit it to n+1 as there is for regular interception.
2050 * Clarified deity reversion of sectors in Sector-ownership.t
2051 * Clarified production efficiency and added pointer to "show sector cap"
2053 * Clarified nuketype selector for planes in Selector.t
2054 * Clarified that fortifying units does not affect mission status in info
2055 pages for mission and fortify.
2056 * Clarified fuel syntax upon error in fuel command in empmod.c.
2057 * Cleaned up comments causing minor complaints in some builds.
2058 * Fixed bug in loans where you could collect on proposed loans.
2059 * Fixed production command to be more accurate (though it *still* has some
2060 rounding errors, it's better.)
2061 * Fixed potential memory leak in air defense missions.
2062 * Fixed bug where you couldn't pinbomb some commodities if other commodities
2063 didn't already exist in the sector.
2064 * Fixed bug where you couldn't build 0 crew planes without military in the
2065 sector. (This is different from needing at least 1 military to build all
2066 planes that need a crew which introduced another related bug earlier.)
2067 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
2068 messages to be displayed for deity owned planes.
2069 * Fixed bug where land units on ships in a sector taken over were blown
2071 * Fixed bug where planes on ships in a sector taken over were blown up
2073 * Fixed bug in sdump printing origx and origy in deity coordinates.
2074 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
2076 * Fixed bug in launch showing wrong satellite target (showed asat instead
2077 of the target satellite.)
2078 * Fixed bug where you could gain information not normally available using
2079 the "fire" command to determine sector type information.
2080 * Fixed bug in market/trade creating extra money when loans are taken out.
2081 * Fixed problem with land units not being reported sunk after being sunk
2082 on a ship that was nuked or wastelanded in a sector.
2083 * Fixed problem with Spies.t using "llook" instead of "llookout".
2084 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
2085 on some Linux boxes.
2086 * Fixed problem with plague infection being way too high in cities when
2087 the BIG_CITY option is enabled.
2088 * Fixed bug in edit command getting confused with arguments.
2089 * Fixed bug in ask_move_in_off asking you to move in a negative number of
2090 troops (hey, it could happen. :) )
2091 * Fixed bug in add command not keeping flags or relations initially correct.
2092 * Fixed bug in torpedo command sometimes telling victim about torpedo
2093 sightings even when way out of range.
2094 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
2095 as not formatting them properly when reporting them.
2096 * Fixed bug in satellite with noisy transmission causing a potential
2097 crash of the server with non-100% efficient satellites.
2098 * Fixed potential crashing of the server during satellite display when not
2099 calculating distances to ships and units correctly.
2100 * Fixed bug where planes in non-allied sectors, ships and units could be
2102 * Fixed bug where planes on the trading block could be used on missions.
2103 * Fixed bug where planes and units that get traded don't have mobility set
2104 correctly when using MOB_ACCESS option.
2105 * Fixed bug which made security units virtually useless.
2106 * Fixed access times and mobility not being set right when building planes,
2107 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
2108 * Fixed minor formatting problem with launch of satellites.
2109 * Fixed minor formatting problem with planes with greater than 999 tech.
2110 * Fixed minor formatting problem with ships with greater than 999 tech.
2111 * Fixed problem with "llook" showing up in TOP info file.
2112 * Fixed problem with lwp Makefile choking on NT builds with clean target.
2113 * General cleanup of potentially ambiguous statements.
2115 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
2116 * Added "TECH_POP" as an option where technology costs more to make
2117 as your population grows past 50K civilians. It is disabled by
2119 * Changed "produce" command to accurately print what the true p.e. is.
2120 * Changed "update" command to display if mobility updating is enabled for
2122 * Fixed bug where toggling off the coastwatch flag also turned off
2123 forts firing on hostile ships coming into range.
2124 * Fixed bug where assaulting your own land would violate any treaties
2125 you have where assaults are a violation.
2126 * Fixed bug where all planes (even those without need for a crew, such
2127 as missiles) needed at least 1 military to build.
2128 * Fixed bug where when a ship sinks during the update due to lack of maint,
2129 land units and planes on it were left stranded.
2130 * Fixed bug where when a land unit dies during the update due to lack of
2131 maint, land units and planes on it were left stranded on it.
2132 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
2134 * Fixed bug in "show sector capabilities" not showing products correctly.
2135 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
2137 * Fixed bug in sectors that don't revolt not showing up as lost items.
2138 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
2139 * Fixed bug where MOB_ACCESS was not updating the mobility just before
2141 * Fixed bug in the way treaties are examined and sometimes produce
2143 * Fixed edit to allow creating negative mobility for sectors.
2144 * Fixed setsector to allow creating negative mobility for sectors.
2145 * Fixed bug where when writing out the value of a sector that had
2146 negative mobility and was damaged in combat, mobility was being
2148 * Fixed Taxes.t info page to reflect that captured civvies only pay
2150 * Fixed Technology.t info page to reflect TECH_POP option.
2151 * Fixed navigate.t info page to reflect that only ships in the fleet
2152 in the same sector that are fired upon have damage divided up.
2153 * Made techlists toggle on by default (so things are shown in order of
2154 technological advances.)
2156 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
2157 * Added optimization to increasing mobility to check if an object is
2158 already at max mob, just return since it can't be increased.
2159 * Added "-ltermcap" for client libs for hp build (it was already in
2161 * Added clearing of telegram flags after the update so that the next
2162 telegram is flagged as new and not part of the update.
2163 * Fixed Update-sequence.t to reflect MOB_ACCESS.
2164 * Fixed bug where fortification amount was not being limited to
2165 maximum mobility for land units (land_mob_max).
2166 * Fixed bug where land unit fortification strength was being calculated
2167 by using 127 instead of land_mob_max.
2168 * Fixed bug where scrapping land units was creating military.
2169 * Fixed description of sect_mob_neg_factor in econfig file.
2170 * Increased speed of PT boats.
2172 Changes to Empire 4.2.4 - Tue Feb 2 05:47:44 PST 1999
2173 * Added check to make military values match up correctly for land
2175 * Fixed bug in doconfig not putting ipglob.c in the right place.
2176 * Fixed bug where attacking deity sectors will violate a treaty.
2177 * Fixed newspaper.t information file.
2178 * Fixed potential bug in fixing up timestamp information when restarting a
2179 game with MOB_ACCESS turned on.
2180 * Fixed bug in explore command not setting mobility to correct
2181 value when MOB_ACCESS was enabled.
2182 * Fixed bug in enlist setting mobility incorrectly sometimes.
2183 * Added doc/backup file for deities which recommends how backups and
2184 restores of the data directory should be done.
2186 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
2187 * Added linux-pthreads target and build for using pthreads under Linux.
2188 * Added NO_FORT_FIRE option which disables the ability of forts to
2190 * Added more error checking and recovery for corrupt data files.
2191 * Changed alphapos target to alpha-pthreads for better clarity.
2192 * Changed fairland to allow 0 sector distance to other islands and
2193 continents (James Risner)
2194 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
2195 match the way ships are described (since this is how they really work.)
2196 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
2197 and "fir" as the number of guns that a land unit fires.
2198 * Cleaned up misc. build warnings.
2199 * Changed artillery damage to be 5 + d6 per gun firing from just d6
2200 per gun firing and updated Damage.t to reflect this change.
2201 * Changed artillery firing ranges to be like ships ranges - divided
2202 by two, and modified them to make more sense.
2203 * Changed artillery units to be "slightly" :) more powerful.
2204 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
2205 * Changed "artillery" unit to tech 35.
2206 * Changed so that guns are no longer required to build units, and
2207 that guns must be loaded onto artillery units for them to fire.
2208 Client developers note: the show command has not changed yet to
2209 remove the 'guns' column (since guns are no longer required) but
2210 will in a future revision (possibly 4.2.4) so "be prepared" for
2211 "show land build" to change. :)
2212 * Fixed landunitgun to handle all the damage calculations like it should.
2213 * Fixed bug sinking planes when the ship they are on sinks.
2214 * Fixed bug destroying planes when the land unit they are on is destroyed.
2215 * Fixed bug where land units could fire support without enough military.
2216 * Fixed bug in abandoning sectors by marching out a land unit where it
2217 would not let you sometimes (uninitialized variable problem.)
2218 * Fixed gets problem in files.c (James Risner)
2219 * Fixed bug in determinig operations range of a ship.
2220 * Fixed bug in building planes where you could manufacture military.
2221 * Fixed warnings in threading package(s).
2222 * Fixed fire.t to reflect new firing changes.
2223 * Fixed lstat.t to reflect new firing changes.
2224 * Fixed sstat.t to reflect the way things really work.
2225 * Fixed Ship-types.t to reflect the way things really work.
2226 * Fixed the way shutdowns work to hopefully better protect data files.
2227 * Fixed bug in attacking when sector mobility is less than 0 and it would
2228 prompt for attacking with a negative amount of military.
2229 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
2230 * Fixed bug in client when it prompts for country name it was putting
2231 an extraneous end of line on the end that needed to be stripped off.
2232 * Fixed problems running on Linux running on an Alpha machine. Thanks
2233 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
2234 on a machine to work out the bugs. (Note that the only build that
2235 works on Linux/Alpha is the linux-pthreads)
2237 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
2238 * Added some code optimizations into the update code when building paths.
2239 * Added some new cacheing for building paths to help speed up updates.
2240 * Added so that you can use "name" and "password" with the change command
2241 as well as "country" and "representative".
2242 * Added flag to power command so that if you are a deity and enter
2243 a negative number of countries you want to see, you see the power chart
2244 for that many countries without power numbers on the next line. Only
2245 useful for deities that want to see the chart un-broken up by that line.
2246 * Added new functionality to fortify command. You can now use a negative
2247 fortification value to cause the unit to be fortified and leave at
2248 least that much mobility on the unit. I.E. "fort * -67" will fortify
2249 all units and make sure the mobility of each unit doesn't go below
2250 67. If the mobility is already below that level (or equal) the unit
2252 * Added that the realm command prints "Realm #n is x:x,y:y" after
2253 you set a new realm.
2254 * Added TREATIES option and enabled it by default.
2255 * Added "no depth-charging subs" and "no new land units" treaty
2257 * Added Trannie Carter's basic client fix to use fgets instead of gets.
2258 * Changed market and command to only print the lowest priced lot of
2259 each given commodity by default. If you specify "all" it shows
2260 all lots on the market, and if you specify a specific item, it shows
2261 all lots of that item type.
2262 * Changed start command to only write out sector if it changed.
2263 * Changed stop command to only write out sector if it changed.
2264 * Changed how plane names were changed on server startup if the
2265 PLANENAMES option was enabled.
2266 * Changed move command to use standard askyn function for abandoning
2268 * Changed plane overlight sightings to take stealth into account,
2269 and if the planes managed to evade all flak and interceptors, they
2270 are not marked as "spotted" over enemy sectors.
2271 * Changed all units with the supply flag to have their marching speeds
2272 based on efficiency since that is their purpose. What this means is
2273 that supply units and trains are more effective at 100% than at 10%
2274 (just as fighting units are more effective at 100% than at 10%, but
2275 their effectiveness is determined by how well they fight, not how well
2276 they "run away, run away!" :) )
2277 * Changed so that flash toggle is on by default for POGO at setup
2279 * Changed so that when a sector is taken, all land units owned by the
2280 current owner are treated as planes are during takeovers (i.e. there
2281 is a pretty good chance they are blown up, and if not, they change owner
2282 to the attacker and are beat up pretty good.)
2283 * Fixed treaties to work again.
2284 * Fixed bug in taking over land units not using correct pointer (can
2285 cause a crash or data corruption.)
2286 * Fixed collect command to wipe deliver and distribution information
2288 * Fixed potential bug in bmap not working when destination bmap has
2290 * Fixed bug in shark command not getting right nation structure.
2291 * Fixed bug in server where empty commands (for example, all spaces
2292 or tabs) were being reported as bogus commands. They are now just
2294 * Fixed bug in scrap not dropping land units off of scrapped units carrying
2296 * Fixed bug in news where boarding of land units was reported backwards.
2297 * Fixed bug in calculating new people when growing them during an update.
2298 * Fixed missing -ltermcap in HP/UX build.
2299 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
2300 later and being reset to 0 anyway)
2301 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
2302 since that is what it really is.
2303 * Fixed retreat.t documentation to reflect the "retreat upon failed
2305 * Fixed bug where satellites were not orbiting the world during the
2307 * Fixed bug in torpedos being too smart. They knew how to jump over
2308 land! :) Now the "line_of_sight" routine is used to determine if a
2309 torpedo has a straight path to the destination. If it doesn't, the
2310 torpedo no longer jumps over land, but instead slams into it. This was
2311 an interesting bug because you could torp ships on the other side of
2312 a very skinny island as long as they were in range, even if there was
2313 no sea route possible.
2314 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
2315 units for example) but you still have to pick something to bomb. For
2316 ships it worked ok (just aborted that it couldn't find any more ships)
2317 and this was fixed for land units and planes.
2318 * Fixed server crashing bug when flying a plane and not carrying
2320 * Fixed bug in move losing commodities when it runs out of room in the
2321 destination sector. Goods are now attempted to be returned to the
2322 start sector, and apporpriate steps taken if the start sector is no
2324 * Fixed march to prompt you before you abandon a sector you own by
2325 marching out the last land unit.
2326 * Fixed check functions to only check the relevant portions of the structure
2327 and not the timestamp info that doesn't affect how the object functions.
2328 * Fixed bug in spy command that always told you if a spy unit was in a
2330 * Fixed bug in displaying of land unit missions not showing correct land
2332 * Fixed bug in wire command where new announcements that you read at
2333 the last second don't get wiped out properly.
2334 * Fixed bug where announcement file could be corrupted by very long lines.
2335 * Fixed bug where bmap was not set when player was told what kind of
2336 sector they were attacking (this was an old abusable bug that was
2337 removed long ago to fix the abuse, and it's been fixed in a non-abusable
2339 * Fixed bug where change command would warn you about monetary and
2340 BTU costs, but not prompt you to break out if you didn't want to really
2341 change your country name.
2342 * Fixed bug in sub-launched nukes that are intercepted being reported in
2343 the news incorrectly.
2344 * Fixed bug in load where you could abandon a sector and not know it by
2345 loading your last civilians or military onto a ship.
2346 * Fixed potential memory leak in autonav code.
2347 * Fixed potential bug where you could possibly determine if a sector is
2348 owned or not using one way plane missions.
2349 * Fixed Damage.t info page to properly show damages for planes and
2351 * Fixed deliver.t to include syntax for command.
2352 * Fixed country.t to include syntax for command.
2353 * Fixed bug where ships on orders were not adding radar information to
2354 the bmap during an update.
2355 * Fixed bug where ships on sail were not adding radar information to
2356 the bmap during an update.
2357 * Fixed bestownedpath code to use the bmap properly. Note this is a very
2358 important bug fix. When navigating a ship, players are no longer given
2359 free information that they would not normally know. For example, if you
2360 try sailing your ship off into uncharted areas of your bmap, the bestpath
2361 code will only use as much information as you have on-hand (i.e. your
2362 bmap) to plan out your path for you. If you have no information on an
2363 area, it just keeps forging on, until bumping into something. Of course,
2364 after the initial exploration through an area, the bmap will be set and
2365 used for all future sailings through that area. Harbors and bridges
2366 are still checked for construction worthiness if you know where they
2367 are (i.e. they are on your bmap.) (Overall, what happened before
2368 was that the bestpath code would route your ship around islands that
2369 you didn't even know were there, and you could use various commands
2370 to see how that ship was going to sail during the update and thus you
2371 gained information that you wouldn't normally know.)
2372 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
2373 and "BestAirPath" to use it properly. It is also good to note that
2374 bestownedpath is used to determine paths for ships and for planes,
2375 and that best_path (which uses the A* algorithm) is used for all land
2376 based paths, and that the two are never interchanged.
2377 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
2378 and RECON was never used before.)
2379 * Removed extraneous "resnoise" and "resbenefit" functions and combined
2380 the two for setresource and setsector commands.
2382 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
2383 * Fixed problem with global/plane.c not defining last structure element
2384 properly, and thus causing crashes when accessing certain plane
2385 routines. This happened during the move to make the PLANENAMES option
2386 run-time configurable.
2388 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
2389 * Bumped rev to 4.2.0 since this is a major release (the server is now
2390 run-time configurable for just about everything and is released under
2392 * Put in official licensing information.
2393 * Re-arranged and commented the econfig (Empire Configuration) file. The
2394 auto-generated "data/econfig" file is now pumped out chock full of
2395 comments (which may or may not be useful.) Since the server is
2396 pretty much fully run-time configurable (MAXNOC is not, but it gets
2397 a default of 99 anyway) deities will probably be spending more time
2399 * Added server support for building under NT, including mods from
2400 Doug Hay and Steve McClure to get the server building and running
2401 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
2403 * Added Doug Hay's ntthread.c implementation for NT threading.
2404 * Added max pop column to "show sector stats" output.
2405 * Added lboard command for boarding land units from sectors. Only raw
2406 mil can board land units, and only mil and land units aboard the unit
2407 being boarded fight back.
2408 * Added GODNEWS option. When enabled, the deity giving people stuff
2409 is shown in the news.
2410 * Added bridge tower sector ('@')
2411 * Added BRIDGETOWERS option. When enabled you can build bridge towers
2412 from a bridge span. You can then build bridge spans from the tower.
2413 If the tower is destroyed ( <20% eff) bridges connected fall unless
2414 supported on the other side. You can only build bridge towers in open
2415 water not adjacent to land and other towers. Expensive.
2416 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
2417 it is deity creatable only (can't redesignate unless you wasteland it
2419 * Changed "info all" to no longer use printdir, instead it just uses the "all"
2420 info page which contains this information.

2422 submarines if the LANDSPIES option is enabled. Useful for sneaking up

2427 * Changed show command to show tower stats ("show t b")

2437 * Fixed distribute command to only write out to the database if we
2438 actually changed the sector (i.e. if we really moved the dist

2464 shouldn't, or not taking them out when it should.

2466 (note that it doesn't happen since only HEAVY units can carry other
2467 units and that check works, but that might change some day, and we
2468 don't want units carrying units to be carried by other units, etc. :) )

2560 military personnel on board to see anything.
2561 * Fixed "llookout.t" to reflect change for military requirement.

2877 * Fixed bug in that if mission_mob_cost was set to 0, even negative
2878 mob units should be able to be put on missions.
2879 * Removed restriction on things needing to be at least 60% to be put
2880 on a mission. Note that while you can put them on missions at < 60%
2881 now, when trying to do the mission, it still checks the eff. This
2882 is to help in automatic setup (build, put on mission, forget) instead
2883 of having to come back repeatedly.
2884 * Spies caught in Neutral or Friendly countries cause the Neutral or
2885 Friendly country to go Hostile towards the owner of the spy.
2886 * Tweaked ammunition numbers for artillery units.
2887 * No more automatic declarations of War should be made. You will go
2888 hostile, but since going to war doesn't increase your countries
2889 defenses, and is purely political, it is left to the player to go
2891 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
2892 * Fixed bug in "lmine" that was crashing the server if the land unit was
2894 * Fixed buy so that if you specify a product, you can only bid on that
2896 * Added "lost.t" info page.
2897 * Added "lost items" database (EF_LOST)
2898 * Fixed bug where you could move in allied forces after an attack if they
2899 bordered the victim area.
2900 * Fixed nstr_comp to deal with values > 16 bits coming in from
2901 client for comparisons.
2902 * Changed last minute market/trade timers to increment 5 minutes. 2 minutes
2904 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
2905 * Commented out the logging of the market checking in server/marketup.c,
2906 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
2907 pretty much useless data that made parsing the server.log file more
2908 more difficult than it needed to be.
2909 * Fixed crashing bug in ldump.
2910 * sdump, ldump, ndump, pdump and dump now print out the current
2911 timestamp on the "DUMP XXX" line.
2912 * Fixed denial of service bug in lib/player/accept.c in
2913 player_find_other function.
2914 * Fixed bug in shark reporting incorrect buyer of the loan.
2915 * Fixed bug in sdump.c (case 0 should have been case 10)
2916 * ldump and sdump now always print the fuel column if asked for,
2917 even if opt_FUEL is turned off. In the case that it is turned
2918 off, the fuel is listed as 0.
2919 * Added "timestamp" field, which is updated every time an item is
2921 * Fixed up the Clients.t info page.
2922 * sdump now prints trade ship building origin.
2923 * sdump now always prints name even if SHIPNAMES isn't defined. If
2924 it is not defined, then the name is empty.
2925 * Added "timestamp" to info/Concepts/Selector.t
2926 * Added some more relevant info to info/Server/Empire4.t
2927 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
2928 is no longer torn down when a sector is re-designated.
2929 * Fixed sell.t to more accurately reflect the time-delay market.
2930 * Fixed read.t and wire.t to reference accept and reject.
2931 * Fixed reject.t not referencing accept command.
2932 * Fixed collect.t to more accurately reflect what goes on when collecting
2934 * Fixed financial.t to reflect defaulted loans.
2935 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
2937 * Fixed "census.t" (had incorrect reference to "info syntax" instead
2940 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
2941 * Increased damage from depthcharges because on increased damage from
2942 torpedos. Sub frange decreased to be more balanced with destroyer frange.
2943 * Intelligence reports (spy) on units will now report the estimated number
2945 * Fixed equation for ship visibility so it will drop as tech increases.
2946 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
2947 land units, planes, and nukes.
2948 * If fields are provided, dump will only supply those fields requested.
2949 * Decreased speed of subs.
2950 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
2951 required for infrastructure improvements.
2952 * Units that lose an assault or a boarding attempt from a ship will no
2953 longer swim back to the ship they came from.
2954 * Units that take extra casualties will no longer lose all their mil at
2956 * Infrastucture is retained when redesignating a sector.
2957 * Dieing spies will no longer crash the server.
2958 * Units, planes, and ships must have mobility to perform missions.
2959 * Units on ship being scrapped are transferred to harbor.
2960 * Food is no longer autoloaded onto units when they are built.
2961 * Fixed show plane stat to show correct range.
2962 * Infantries now take damage at same rate as casualties.
2963 * Fixed bug with hap_fact. Having more happiness now helps with fighting
2965 * Fixed anti to write back target country so che will continue to fight
2967 * Fixed llookout to show correct estimate on number of mil on unit.
2968 * Added buildable architecture "hp". This type will build the server on
2969 a HP/UX machine using the standard compiler instead of gcc.
2971 Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
2972 * Fixed bug in update/distribute.c where pathcost was not being called with
2973 the MOB_ROAD argument (and thus distribution costs could be GREATLY
2974 affected.) - Thanks Ice!
2976 Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996
2977 * Fixed Solaris port using gcc.
2978 * Fixed doconfig.c to create directories with right modes.
2979 * Fixed install macros in makefiles to move binaries to the right
2982 Changes to Empire 4.0.3 - Wed Dec 4 22:46:53 EST 1996
2984 * Fixed doconfig.c (put exit(0) at the end of main.)
2985 * Fixed improve.c (moved the prompt[] string outside the fcn.)
2987 Changes to Empire 4.0.2 - Mon Oct 14 12:26:40 EDT 1996
2988 * Put in LND_MINMOBCOST in land.h
2989 * Put in change in lnd_mobcost in lndsub.c
2990 * Put in new nuke costs in nuke.c
2991 * Put in fix so that total work can only be done by the max pop. No more extra
2992 civvies tossed in will do it anymore in human.c.
2993 * Put in fix for src/util/Makefile - beefed it up.
2994 * Put in fix to show where your ship is when it gets shelled in mfir.c.
2995 * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in
2997 * Fixed Update-sequence.t.
2998 * Put in fix for mobcost bonus for 0% highways.
3001 * Spruced up torpedo damage somewhat. :) :)
3002 * Fixed "assault bmap bug" in attsub.c
3003 * Fixed Produce.t (bars cost)
3004 * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
3008 * Fixed "offer" and "consider" not being legal commands in player/empmod.c
3011 * Fixed lstat.c, pstat.c and sstat.c
3012 * Fixed cutoff command in cuto.c
3013 * Fixed attack value in attack_val in lndsub.c
3014 * Fixed lload in commands/load.c
3015 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
3016 always fight until dead or retreating. 0 makes them get stuck.
3017 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
3018 else for that matter.)
3019 * Fixed llook in commands/look.c
3020 * Fixed che bug in subs/nstr.c
3021 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
3022 of people would starve.)
3023 * Fixed update/human.c - feed_people rounding problems (I hope.)
3024 * Fixed morale problem in update/land.c
3025 * Fixed count_bodies in attsub.c
3026 * Fixed lnd_mobcost.
3027 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
3028 * Fixed interest rate in commands/offe.c
3029 * Fixed bug in buy.c.
3030 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
3031 infrastructure. When off, the defensive infrastructure is the same
3032 as the sector efficiency, and you can't improve it. This is OFF by
3036 * Land units are now built with a default reaction radius of 0.
3037 * Changed name of lt artilleries to "lat" from "lart" so you can now build
3039 * Lowered the speed and firing range of pt boats.
3040 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
3042 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
3043 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
3044 1.5 * ETU_RATE for ships.)
3045 * Conquered civvies only pay 1/4 taxes.
3046 * Railways don't get torn down when you rebuild sectors anymore (but roads
3047 and defenses do (if enabled.)
3049 Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
3050 * Added "extern double tradetax" to check_trade in trad.c
3051 * Improved description of data directory in build.conf
3052 * Fixed bug in attacking land units that retreat so they now get
3053 charged mobility for attacking.
3054 * Fixed dump to report road, rail and defense of a sector at the end.
3055 * Fixed doconfig bug in not checking the right directory to see if the
3056 "data" directory existed or not before trying to create it.
3057 * "change" now works for sanctuary countries.
3058 * Fixed the description of "sinfrastructure".
3059 * Added more info to "Infrastructure".
3060 * Units/planes are no longer reduced to 75% when bought from the trading
3062 * Supply units were slowed down to the speed of infantry units.
3063 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
3064 * Bars interest is up to $250 per 1K again.
3065 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
3066 * Fixed various info pages.
3067 * Fixed bug in people not getting truncated when broke (this was thought
3068 to be fixed, but wasn't. Now it is, dammit!)
3069 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
3070 * Market/trade taxes and trade ship payoff figures were added to version.
3071 * "cede" has been removed as a default command.
3072 * Makefile rule was fixed for depend build.
3073 * Fixed bug in mapdist not taking world edges into account nicely enough.
3074 * Added a "scuttle" order for autoscuttling trade ships. Makes using them
3075 easier. Cleaned up scuttle code while in there.
3076 * Fixed bug with scuttling a ship with units on it not scuttling the units
3079 Changes to Empire 4.0.0 - Wed Aug 21 1996
3080 * Initial Wolfpack release - Long live the Wolfpack!!!!
3081 * Cleaned up the build environment. Now all that is needed is to edit the
3082 build.conf file, answer the questions there and type "make <arch>" to
3083 build for a specific architecture. Thus, no more reliance on gnumake
3084 or special shell scripts.
3085 * We are now shipping the pre-built info pages with the server for those who
3086 Don't want to build them. You can also still just type "make" and have
3087 the info pages build, but it doesn't completely work (i.e. rebuild new
3088 Subjects) if you don't have perl5 installed.
3089 * Put in the "help" command that does the same thing as "info".
3090 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
3091 wish to support it. 2) We envision a better scheme for doing similar
3092 things will come along.
3093 * Put in MOB_ACCESS - This allows real-time updating of mobility.
3094 * Put in MARKET - This is the time-based market (yes, still teleports,
3095 but it's not as bad as it was.)
3096 * Lots of the documenation has been updated, but there is more to do.
3097 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
3098 enabled, you don't need any of that type of material to build things.
3099 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
3100 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
3101 any materials to build a bridge.
3102 * There is no mobility cost for assigning missions. But, there is also
3103 no longer any benefit for being on a mission either.
3104 * Damage is the same for all commodities (people too.) This means you
3105 can deity shell/bomb sectors again.
3106 * Units are now dependant on tech. What this means is that their statistics
3107 now increase with tech. In addition, there is only 1 type of each basic
3108 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
3109 This reflects the idea that as you learn more, you learn how to not only
3110 build better units, but you learn to build units better. :) This also
3111 opens the door for a "lupgrade" command along the same lines as the
3112 "upgrade" command for ships.
3113 * Units now have a minimum mob cost for attacking a sector. Marching
3114 mob costs have not changed.
3115 * Starting units have been removed. This means that at the beginning, people
3116 may live a little longer since their neighbor can't come visiting quite
3118 * Shells are no longer required to build units.
3119 * Mil are no longer required to build units.
3120 * Mil are no longer an intrinsic part of a unit. They are now a loadable
3121 commodity. The way a unit's defense/att bonuses work now are
3122 attack = (att * mil * eff)
3123 defense = (def * mil * eff)
3124 In addition, when a unit takes damage, both the eff and the mil go
3125 down. You can quickly toss in new hacks, but you need to wait to repair
3126 the unit at the update. Thus, you can now look at unit's efficiency
3128 * You need at least 1 mil on a unit to march it (spies are the exception.)
3129 * Units always react if in range and they have the mobility, no matter
3130 what their efficency.
3131 * Units may now march anywhere - in your own sectors, deity owned sectors
3132 or allied sectors, with 1 exception, spies. Also, your units can get
3133 trapped if your ally declares non-alliance with you while your units
3134 are still in his country.)
3135 * Units always march at their speed, efficiency doesn't matter.
3136 * LANDSPIES was added - This creates land unit based spies. Spies may march
3137 anywhere, with a chance of getting caught (except in allied territory.)
3138 See "info Spies" for more info on them.
3139 * Planes may now be based out of allied airports. Landing planes on
3140 ships/sectors you do not own no longer changes thier owner. You can only
3141 land on owned/allied sectors/ships, and you may only
3142 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
3143 you are allied with goes hostile at you, your planes are now stuck there.
3144 Note that if you are using an allied airport, their commodities get
3145 sucked up, not yours (obviously.)
3146 * Planes are now tech-based. Their statistics increase as their tech
3147 increases. Deleted extraneous planes.
3148 * There is a new toggle, "techlists", which allows you to see what you
3149 can build/stats/capabilities sorted by tech instead of groupings.
3150 * Ships are now tech-based. Their statistics increase as their tech
3151 increases. Deleted extraneous ships.
3152 * Che can now be lessened by making happiness. If you have more happiness
3153 than your conquered populace, they don't fight as hard or recruit as
3154 much. If you have less than them, they fight harder and recruit more.
3155 It's not much though - it ranges from 2.0 in your favor to only 0.8
3156 against you (whereas it was always 1.0 before.) So, it definitely
3157 favors the attackers to make lots of happy now.
3158 * Bridgeheads can only be built on coasts.
3159 * Players command was fixed so you only see allies, and don't get
3160 approx #'s of players anymore.
3161 * POSIX threads support has been added.
3162 * The attack bmap bug has been fixed.
3163 * BTUs regenerate 3 times faster now.
3164 * GRAB_THINGS is off by default.
3165 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
3166 as a default (you couldn't make wasteland before with FALLOUT, now
3168 * You can now deliver military and civilians.
3169 * Added SHIP_DECAY option - off by default (turns off ships decaying out
3170 at sea if not enough mil.)
3171 * The reverting owner bug has been fixed in territory, thresh, dist
3172 and deliver. There are probably more, and when found, will be fixed.
3173 * The "sectors don't starve when stopped or broke" bug has been fixed.
3174 * The "people never get truncated" bug has been fixed.
3175 * Added infrastructure to sectors. What this means is that a sector
3176 can now have it's mobility improved by building both roads and
3177 railways. It also means that a sectors defense is now based on the
3178 defensive infrastructure you build into the sector (no more intrinsic
3179 better defenses based on the sector, you determine which sectors are
3180 defended heavily, and which aren't.)
3181 * The defensive value of a sector no longer relies on the efficiency of
3182 the sector. Instead, it relies on the defensive efficiency of the sector.
3183 Thus, the "production" and "defensive" aspects of sectors have been
3185 * "show sect stats" now shows the maximum defensive value for sectors.
3186 * Changed sector structure to take floats for off/def values so we can use
3187 a base of 1 instead of 2.
3188 * Added "improve" and "sinfrastructure" to support the infrastructure
3190 * Added L_TRAIN units which can only travel along railways. Very fast on
3191 efficient railways, slow on non-efficient ones.
3192 * Added the ability for units to carry other units.
3193 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
3194 * Forts only cost $500 to build and 100 hcms now (since they don't get any
3195 better defenses automagically.)
3196 * Modified "show sect build" to show the costs for building up the
3197 infrastructure of a sector.
3198 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
3199 spyplanes too) to show the new infrastructure stuff, rounded of course.
3200 * Added Drake's info->html scripts, with some modifications, so you can
3201 now type "make html" and have your info pages built as html files too.
3202 This adds a new directory, "info.html", to the build tree.
3203 * Modified upgrade so that planes and land units may now be upgraded.
3204 * Added pstat command to list the statistics of your planes.
3205 * Added lstat command to list the statistics of your land units.
3206 * Added sstat command to list the statistics of your ships.
3207 * Added nmap command to show a map of your sectors after their new
3208 designations have taken place.
