1 Changes to Empire 4.3.26 - Mon May 24 16:37:40 UTC 2010
2 * Land units loaded on ships or land units can no longer fight che.
3 * When foreign land units were present, a che revolt could damage
4 them instead of the defending land units. This could let defenders
5 survive the revolt. They were captured or blown up if che took
7 * Fix che revolt to damage only land units that actually fight
8 * Fix loading x-light missiles on ships without capability plane.
9 These ships could only use their x-light slots for x-light planes,
10 not their plane slots. Broken in 4.3.17.
11 * Update bmap when nuclear detonation makes wasteland.
12 * Fix fly and drop to report discarded cargo items correctly.
13 * New client option -s to specify server host and port.
14 * Hitting landmines could crash the server. When not, the damage
15 reduction for capability engineer was applied unpredictably.
17 * Fix retreat and lretreat condition 'c'. Broken in 4.3.16.
18 * coastwatch and skywatch could see too far. Up to one sector for
19 practical radar ranges.
20 * skywatch now reports satellite uids. The uid is required for
21 launching a-sats since 4.3.23.
22 * Fix client not to send an empty line of input before aborting the
23 command on player interrupt (normally ^C).
24 * Fix sabotage not to kill the spy every time. Broken in 4.3.17.
26 * Info page fixes, manual page improvements.
28 Changes to Empire 4.3.25 - Sun Mar 21 08:27:37 UTC 2010
29 * Hitting seamines could crash the server. When not, the damage
30 reduction for capability sweep was applied unpredictably. Broken
32 * When an interdiction did damage other than collateral damage, the
33 planes that intercepted it from interdicted carriers used no
34 petrol. 4.3.24 fixed only the "no damage" case.
35 * Ship anti-missile defense failed to charge shells when the ship was
36 interdicted. The fix in 4.3.24 covered only launch.
37 * Fix a bug in navigate and march that let players lay mines free of
38 charge. Also fix them not to prompt for the number of mines.
39 * Missile exploding on launch could not damage its base if it was
40 armed with a nuke. Broken in 4.3.23.
41 * When a torpedo attack triggered a return torpedo, the news reported
42 it to be fired by the attacker instead of the defender.
43 * Interdiction attacked submarines with surface-only weapons. Broken
45 * Fix a bug in lradar, path, radar, route, satellite, sect and survey
46 that could leak maps to other players. Broken in 4.2.0. Fixed in
47 4.2.8 for bmap, lbmap, lmap, map, nmap, pbmap, pmap, sbmap and smap
49 * files could clobber the game when reading confirmation fails.
50 * fairland no longer rejects small worlds without trying.
52 Changes to Empire 4.3.24 - Tue Jan 26 21:29:14 UTC 2010
53 * The client sometimes hung under Windows when the server closed the
54 connection. Broken in 4.3.23.
55 * Fix navigate and march not to crash the server when a path argument
56 consists of a valid path plus whitespace. Broken in 4.3.7.
57 * When a client sent a blank line in the login phase, the server
58 crashed on some systems.
59 * Fix crash bug in bomb, drop, fly, paradrop, recon and sail. Broken
61 * Fix bogus internal error on escort, recon, and satellite launch.
62 Mostly harmless, as error recovery worked fine. Broken in 4.3.23.
63 * Stop ship and land unit movement on interdiction even when it does
65 * When an interdiction did no or only collateral damage, the planes
66 that intercepted it from interdicted carriers used no petrol, and
67 interdicted land units were immune to collateral damage.
68 * The limit for the number of sectors, ships, planes, land units,
69 nukes, and so forth is now large enough not to matter. It used to
70 be 32768 on common machines. The sector limit was introduced in
71 4.3.12. World x- and y-size are still limited to 65536 on common
73 * News use much less space, and thus I/O. Space was wasted in
74 4.3.12. Side effects of the change:
75 - Expiry of old news no longer updates news timestamps. Updating
76 timestamps was wrong, because it defeated incremental xdump news.
77 - The empdump utility can no longer update timestamps of imported
78 news. Unfortunate, as it breaks incremental xdump news.
79 * New news selector duration, the time span covered by this news item
81 * ABMs failed to charge supplies when their sector was the
82 intercepted missile's target. The stock game's ABMs use no
84 * Ship anti-missile defense failed to charge shells when the ship was
86 * Code refactoring and cleanup.
88 Changes to Empire 4.3.23 - Sun Dec 13 16:34:49 UTC 2009
89 * Fix missile interception not to intercept tactical and marine
90 missiles attacking missiles or satellites. No such missiles exist
91 in the stock game. Interception of tactical ABMs could crash the
92 server. Broken in Empire 2.
93 * Missiles missing their target do collateral damage again. Was
94 disabled because of bugs in 4.0.18 for manual launch and in 4.3.16
96 * News reported victim as actor for sub-launched anti-sat and ABM.
97 * Defense value of missiles vs. ABMs and satellites vs. anti-sats
98 failed to improve with tech.
99 * Fix a bug that let missiles interdict ships outside their op area.
100 This could happen when a group navigating together was partly
102 * Only bomb strategic and launch at sector can use nukes. Before,
103 they could also be used by missions, bomb pinpoint, and launch at
104 ships, but there were several bugs and inconsistencies, and the
105 code was messy. The arm command now rejects marine missiles in
106 addition to satellites, ABMs and SAMs, and clears the mission. The
107 mission command now rejects planes armed with nukes.
108 * Missiles exploding on launch pad no longer set off their nukes.
109 * The launch command now more accurately reports why a missile can't
110 be equipped. It no longer draws supplies automatically.
111 * Manually launched anti-sat now always kills when it hits, for
112 consistency with automatically launched ones.
113 * Don't permit nukes on satellites, ABMs and SAMs. Nukes on
114 satellites could be armed and disarmed even in orbit. Nukes on
115 ABMs and SAMs were lost without effect when their missile
116 intercepted. The stock game is not affected, because its
117 satellites, ABMs and SAMs all have zero load.
118 * Remove obsolete plane capabilities stealth and half-stealth. Not
119 used by the stock game.
120 * Penalize fighter combat value for any load, not just bombs. The
121 stock game's fighters can't carry anything but bombs.
122 * Make bomb work for non-tactical cargo bomber. No such planes exist
124 * Revised cargo plane rules: a cargo flight can be either an airlift
125 or an airdrop now. Airlifts carry more cargo than airdrops. A
126 cargo drop or paradrop with a non-VTOL plane is an airdrop.
127 Anything else is an airlift. This makes paradrop loads consistent
128 with drop loads. Paradrop with VTOL transports now carries twice
129 the punch, and drop with non-VTOL transports hauls less than fly.
130 In particular, the stock game's tr can't drop guns anymore.
131 * Enforce plane selection rules more tightly:
132 - bomb command can select only planes with capability bomber or
133 tactical. Before, other planes with non-zero load flew along,
134 but their bombs were silently lost.
135 - sweep command can select only planes with capability sweep.
136 Before, other planes performed ordinary reconnaissance instead.
137 - drop command can select only planes with capability cargo.
138 Before, other planes flew along but dropped nothing.
139 * Fix paradrop to fail without destroying the paratroopers when the
140 player owns the target sector.
141 * Launching an anti-sat now takes the target plane as argument.
142 Before, it took a sector argument, and targeted the lowest-numbered
143 satellite there. Rather inconvenient when your own satellite masks
145 * Remove option PINPOINTMISSILE. Deities can customize the plane
146 table to disable marine missiles.
147 * Ridiculously impotent nukes could do unpredictable interdiction
148 damage. No such nukes exist in the stock game.
149 * The production command could mispredict resource-depleting level
150 production. No such products exist in the stock game. In fact,
151 they'd be highly unusual.
152 * The update could crash or corrupt the game when a (misconfigured)
153 product depleted resource "none".
154 * Revamp the Windows port based on ideas stolen from Gnulib. Share
155 the code between server and client.
156 * Don't log out player when update aborts a command under Windows.
157 Broken in 4.3.20, and not fully fixed in 4.3.21.
158 * Fix accepting connections from hosts with "long" IPv6 address. The
159 internal buffer had insufficient space.
160 * Delay shutdown up to 3s to let player output buffers drain.
161 * Fix a race between main thread and player threads, which could
162 theoretically make the server crash on start.
163 * Clean up synchronization between commands, update and shutdown, and
164 when player threads sleep on I/O.
165 * Clean up the cruft that has accumulated in and behind the empio
166 interface, and, to a lesser degree, the empthread interface.
167 * Fix time difference underflows in pthread and Windows code. They
168 could potentially cause hangs, although none have been observed.
169 * Make budget's "Sector building" line look better.
170 * Make sector maintenance cost configurable. New sect-chr selector
171 maint. Capitals now pay maintenance regardless of efficiency.
172 * Overhaul show sect b.
173 * Fix mine production resource limit for sector peffic != 100. This
174 affects mountains in the stock game, but only with an impractically
175 large number of ETUs per update.
176 * Code refactoring and cleanup.
177 * Info file fixes and improvements.
179 Changes to Empire 4.3.22 - Sat Apr 25 11:56:29 UTC 2009
180 * Fix a Windows client bug that could lead to hangs, at least with
181 some versions of the C run-time. Broken in 4.3.11.
182 * Allow building without curses terminfo. Highlighting in the client
184 * Really fix bomb not to wipe out plane updates made while it asked
185 for pinpoint targets. The fix in 4.3.21 didn't cover escorts.
186 * Fix tend land not to wipe out concurrent updates.
187 * Fix a bug in automatic supply:
188 - Ships with just two shells could fire a torpedo to return fire or
190 - Ships with just one shell could use their anti-missile defense.
191 - Land units were considered in supply even when they had not quite
192 enough supplies. Such land units could defend without penalty,
195 * Fix update to take dead units off carriers.
196 * Standalone client distribution built empire instead of empire.exe
197 for Windows. Broken in 4.3.0.
198 * Fix client to abort script execution on SIGINT.
199 * Fix Windows client not to hang on EOF on standard input when that
201 * Fix a client bug that could make it hang when EOF on standard input
202 follows an execute command closely.
203 * Seamines under bridge spans were disabled a long time ago, in
204 Empire 2. The drop command refuses to mine there. Change mine
205 command to do so as well.
206 * Seamines under bridge spans were mistaken for landmines by ground
207 combat, land units retreating from bombs, and non-land unit ground
209 * When a bridge tower collapsed, its landmines magically became
211 * Don't log out player when he interrupts a command. Broken in
213 * Code cleanup and portability improvements.
214 * Info file and documentation fixes.
216 Changes to Empire 4.3.21 - Mon Mar 9 21:34:52 UTC 2009
217 * Fix swapsector not to wipe out concurrent changes to the swapped
219 * Fix a bug in crash dumping that could mess up the journal and, at
220 least in theory, mess up commands info, read, turn, and wire;
221 announcement expiry, and reading of econfig and schedule.
222 * Fix bomb not to wipe out plane updates made while it asked for
224 * When bombing ships with a force containing both planes with and
225 without capability ASW, the bomb command could fail to report
226 presence of submarines, and could refuse to bomb ships when there
227 were only submarines.
228 * Leaving land units behind after a victorious attack could in some
229 cases wipe out changes made to them since the victory.
230 * The timestamp selectors added to commodity, load and trade in
231 4.3.12 could lead to spurious command failures. None have been
232 observed in the wild.
233 * Don't log out player when update aborts a command. Broken in
235 * Code refactoring and cleanup.
237 Changes to Empire 4.3.20 - Fri Feb 20 18:14:20 UTC 2009
238 * Option LOANS is now disabled by default.
239 * Option RAILWAYS is now enabled by default.
240 * Many fixes to automatic supply:
241 - Planes flying interception or support missions, abms intercepting
242 ballistic missiles, and the launch command for missiles and
243 anti-sats could all supply more shells than necessary, lose
244 shells, or conjure them up.
245 - Ships shooting down marine missiles could supply more shells than
246 necessary, or lose shells.
247 - Supply ships could conjure up shells when firing guns using
248 multiple shells, or launching torpedoes, or dropping depth
249 charges, or shooting down marine missiles. No supply ships
250 capable of doing that exist in the stock game.
251 - Supply engineers could conjure up shells when laying mines. They
252 don't exist in the stock game.
253 - load, lload and supply could supply land units with enough food
254 from the sector containing them to starve the sector.
255 - Sectors were charged too much mobility for moving supplies
257 - Land units serving as supply source no longer draw supplies
258 recursively, because the bugs there are too hard to fix to be
260 - Defending and reacting units only checked whether they could draw
261 supplies, but didn't actually draw them.
262 - load, lload, supply, assault and board no longer supply land
263 units from ships carrying them. This feature, added in 4.0.14,
264 was inconsistent with other ways to supply.
265 - Don't use automatic supply to avoid starvation at the update. It
266 adds complexity to the update. How much good it does to players
267 is highly doubtful; certainly nobody can rely on it. It isn't
268 covered by the starvation command. Ships or land units could
269 steal enough food from their sector to make it starve.
270 - lmine could only fetch shells for engineers that use ammo. The
271 stock game's engineers all do.
272 The changes listed for load and lload are actually lies, because
273 supply has been disabled there since 4.3.17.
274 * Don't let an engineer lay mines while it is on a ship or land unit,
275 or in a foreign sector.
276 * Sectors and ships no longer need shells to fire flak.
277 * Use IPv4 and v6 only when suitable interfaces are configured.
278 * Fix turn off not to fail when the message is empty. Broken in
280 * Don't nag the deity about game hours restriction in force all the
282 * Tell deity when the game is down, just like players. Also make the
283 information available in xdump, as game selector down.
284 * Corrupt mailboxes could crash the server.
285 * Fix reject accept. Broken in 4.3.4.
286 * If a player was at a prompt when the deity turned the game down, he
287 was allowed to enter one more command.
288 * Air defense is no longer separate from interception. Putting a
289 plane on air defense now merely changes where it intercepts.
290 Separate air defense added too much pointless complexity. Its
291 implementation violated design assumptions of the intercept code.
292 Because of that, the same plane could intercept both an air defense
293 mission and the planes that triggered it, and the damage it
294 received in the first interception was wiped out.
295 * Intercept the same all along the flight path. In each sector, any
296 country owning the sector, a surface ship or a land unit there gets
297 to intercept. Before, only the sector owner got to intercept,
298 except for the assembly point and the target sector. In the target
299 sector, any country owning surface ships or land units got to
300 intercept in addition to the sector owner. Thus, a sector owner
301 with surface ships or land units there got to intercept twice. The
302 sector owner did not get to intercept at the assembly point,
303 even when it was the target sector.
304 * Spotting rule changes:
305 - Ships and land units now spot overflying planes along all of the
306 flight path instead of just the target sector, and no longer
307 report allied planes.
308 - Planes now spot ships and land units only when flying recon or
309 sweep, and along all of their flight path instead of just the
310 target sector. It still takes a spy plane to identify ships and
312 - Planes now spot ships and land units in a sector even when all
314 - Planes now spot all foreign ships and land units, not just
316 * Fix SAM interception for intercepts other than the first.
317 * Fix air defense and flak over sectors allied to the planes. Air
318 defense was broken in Empire 2. Flak was broken in 4.2.8.
319 * Establishing contact by spotting planes from sectors didn't work.
320 * Fix reconnaissance patrols to use sonar when any capable plane is
321 present. Before, all planes had to be capable.
322 * Fix recon and sweep not to spy after all spy planes are gone.
323 * Fix a bug that made multiple clients running on the same Windows
324 machine interfere with each other. Broken in 4.3.11.
325 * Fix enforcing game hours for players already logged in. Broken in
327 * Fix distribution not to abandon a distribution center by exporting
329 * Many fixes to load, unload, lload and lunload:
330 - Now usable for deities.
331 - Plug loopholes that let you steal foreign commodities by making
332 load/lload unload and unload/lunload load through use of negative
334 - Fix not to let you give away civilians.
335 - You can't use lload in foreign sectors or lunload with foreign
336 land units anymore. Loading stuff in foreign sectors was
337 prohibited already for ships.
338 - lload and lunload now work on foreign land units only when
339 they're explicitly named by uid. This matches behavior of load
341 - Fix to test relations of foreign object's owner to player instead
342 of the other way round.
343 * Make sure land units with maximum mobility can attack mountains.
344 * Fix land unit attack mobility cost. Broken in 4.3.6.
345 * Conditions comparing string-valued selectors like wing to unquoted
346 values are now interpreted more smartly. Before, unquoted strings
347 were prone to be interpreted as selector names even when that made
348 no sense. You still have to disambiguate truly ambiguous cases
349 like w=w for planes, e.g. as wing=w or w='w'.
350 * Fix reporting of shot spies in news. Broken in 4.3.16.
351 * Remove econfig key mission_mob_cost. Questionable feature, and
352 hasn't been used in a long time.
353 * Reserve and escort missions now have an op-area, like all the other
355 * Land units now react only when on a reserve mission. The lrange
357 * Fix a bug that could mess up mission op-area when the range of
358 ship, plane or land unit on the mission decreases, e.g. through the
360 * Reserve missions no longer give a bonus to reaction range.
362 * Code refactoring and cleanup.
364 Changes to Empire 4.3.19 - Sun Dec 7 23:15:34 UTC 2008
365 * LWP doesn't work with Darwin due to OS bugs, avoid it for now.
366 * Don't let ships double-retreat first on 'i' (injured) and then on
367 'h' (helpless) when shelled.
368 * Fix a bug that suppressed the "sunk!" message. Broken in 4.3.17.
369 * Log out player when maximum time per day is exceeded. Before, he
370 could remain logged in with visitor privileges only, but once
371 logged out could not log back in.
372 * If a player was at a prompt when either game hours restriction
373 started or maximum time per day was exceeded, he was allowed to
374 enter one more command.
375 * Deitying a capital failed to charge money and report news. Broken
377 * Overhaul accounting of play time, fixing minor inaccuracies.
378 * Fix parsing of 24:00 in econfig key game_hours and
380 * New option RAILWAYS.
381 * Che ages just like military reserves (1% per 24 ETUs).
382 * Permit ships to assault the sector they're in.
383 * Sectors eating less than one unit of food don't make one unit of
384 food for free anymore. They still can't starve.
385 * New concept sector terrain. Deities can use it to make sectors
386 other than wilderness redesignatable. See sect.config for more
388 * Represent play time in seconds rather than minutes. This affects
389 xdump: nat selector minused (counting minutes) is replaced by
390 timeused (counting seconds).
391 * Improved nightly build, with additional tests.
393 Changes to Empire 4.3.18 - Sat Oct 18 18:39:17 UTC 2008
394 * Fix building of planes, land units and nukes with uids that have
395 never been used before. This could crash the server on some
396 systems in certain states. Broken in 4.3.17.
397 * Improved nightly build, with restructured and extended tests.
399 Changes to Empire 4.3.17 - Sat Sep 20 16:07:44 UTC 2008
400 * Fix standalone client build for Windows. Broken in 4.3.11.
401 * Disable automatic supply of land units on load for now, it's broken
402 in a highly abusable way.
403 * Make trade show exactly what's on sale, remove option SHOW_PLANE.
404 * Stop ships, planes, land units and nukes on violent takeover, just
406 * Wipe orders when ships, planes, land units and nukes are taken over
407 violently or given away peacefully. Fleet, wing, army and mission
408 were already cleared in many, but not all cases. Other orders were
409 never cleared: mission op-areas (visible in xdump), ship autonav
410 orders, ship sail path (including ship to follow and mobility
411 quota), land unit retreat orders, plane range limit, and land unit
413 * Fix takeover of stuff by attack, assault, board, lboard, paradrop
415 - Corrupt land unit file could lead to infinite recursion.
416 - Take over nuke armed on plane along with the plane. Broken in
418 - Taking over land units with negative mobility increased mobility
419 to zero. Ditto for planes embarked on ships or land units.
420 * Fix a bug that made set and xdump not recognize unused trade lots
422 * Fix giving away stuff by trading it:
423 - When an armed nuke is sold separately from its plane, take it off
424 the plane. You couldn't do that before 4.3.3.
425 - Give away nuke armed on sold plane along with the plane. Broken
427 - Don't zero mobility of planes and land units on sold ships.
428 * Fix giving away stuff by unloading from its carrier: Give away any
429 nukes armed on planes (broken in 4.3.3) and land units loaded on
430 land units. The latter can't happen in the stock game.
431 * Fix giving away stuff by scrapping or scuttling its carrier:
433 - Disarm the nuke from a plane instead of destroying it.
434 - Give away any loaded land units and planes, too.
436 - Fix scuttle to ask for confirmation when scuttling a tradeship in
437 an unsuitable sector even when the tradeship is pirated. Broken
439 - Fix scuttle to require 2% harbor efficiency for a trade ship to
440 pay. Also require at least friendly relations.
441 - Make autonav refuse scuttle orders in unsuitable sectors.
442 * Clean up rules on where you can scrap stuff:
443 - Ships in own or friendly, efficient harbors (relations used not
444 to matter, contrary to info)
445 - Planes in own or allied, efficient airfields (friendly used to
446 work as well, contrary to info)
447 - Land units in any own or allied sector (relations used not to
448 matter, and you couldn't scrap them on ships)
449 Also tell player why something can't be scrapped instead of
450 ignoring it silently.
451 * Rewrite the broken code to move land units, planes and nukes along
452 with their carrier. The old code was a hack that didn't update
453 timestamps (so incremental dumps didn't pick up the movement), and
454 it didn't cover all uses. The update, in particular, was prone to
455 see cargo in old locations, which could screw up repairs.
456 * Expire lost items at the update instead of continuously.
457 * Replace econfig key lost_items_timeout by lost_keep_hours.
458 * Minor Windows threading fixes.
459 * Journal now uses human-readable names to identify threads.
460 * Ship and land unit load counters are no longer stored in game
461 state, because they duplicate information already there. Same for
462 the type of nuke loaded on a plane. Remove field nuketype from
463 xdump plane. Clients can simply find the plane's nuke instead.
464 * Ship and land unit load counts as displayed by ship, sdump, land,
465 ldump, ship selectors nplane, nxlight, nchoppers, nland, and land
466 selectors nxlight, nland are now reliable. They used to get out of
468 * Ship load counts now reflect what is loaded, not how it is stored.
469 For instance, if a light carrier, capable of carrying 4 x-lights
470 and 20 light planes carries nothing but 5 sams, we now have
471 nxlight=5, nplane=0 instead of nxlight=4, nplane=1.
472 * New cargo lists data structure to let code find loaded planes, land
473 units and nukes easily and efficiently.
474 * Revamped upkeep of lost file. It should be reliable now.
475 * Disable the ill-advised error recovery on sector access that swept
476 bugs under the carpet rather than recovering from them.
477 * Occupied sectors no longer revert to the old owner when all
478 military and land units go away. This feature was added in
479 Chainsaw 3. It wasn't integrated properly with the che code
480 (things went wrong when che killed all defenders, but couldn't
481 convert the sector due to its loyalty), and combat code (if an
482 attack killed off all local defenders and got defeated by reacting
483 units, the sector changed ownership anyway, silently).
484 * Include destination coordinates in interception and plane mission
486 * Client could misdiagnose redirections and executes as unauthorized,
487 or die outright. Broken in 4.3.11.
488 * Fix xdump realm to dump player instead of absolute coordinates.
489 Disclosed the true origin. Broken in 4.3.0.
490 * Fix spy to reliably avoid spying same sector more than once.
491 * The map drawing code could smash the heap when the world was
493 * When a satellite's launch trajectory was off, its coordinates could
494 get screwed up, which made it invisible in skywatch.
495 * Fix several bugs that made the path command screw up when the path
497 * Fix the default size of the map shown by move, test and transport
499 * Fix bugs that could make arguments in area or dist syntax miss
500 ships, planes, land units and nukes at the border of the selected
501 area, if that area spans the whole world. In sufficiently small
502 worlds, it could also make radar miss satellites and ships, sonar
503 miss ships, satellite miss ships and land units, nuclear
504 detonations miss ships, planes, land units and nukes, automatic
505 supply miss ship and land unit supply sources, ships and land units
506 fail to return fire, ships fail to fire support.
507 * Maps sometimes showed x-coordinates as three lines instead of two
509 * Improved nightly build, tests in particular.
510 * Code refactoring and cleanup.
512 Changes to Empire 4.3.16 - Sat Aug 9 15:56:52 UTC 2008
513 * Production command incorrectly limited the number of graduates,
514 happy strollers, technological breakthroughs and medical
515 discoveries produced by a sector to 999. Broken in 4.2.15.
516 * Fix a bug in improve that could let you spend more money than you
518 * Fix work command not to spend more mobility than requested, and to
519 round mobility use randomly instead of down.
520 * Commands demobilize, convert and work no longer let you spend more
521 money than you have. Commands demobilize and convert no longer ask
522 for confirmation before spending more than half your money. Saving
523 that feature would have been more work than it's worth.
524 * Remove undocumented key 'd' at bomb ship, plane and land unit
526 * Fix land unit flak when pin-bombed to match flak when overflown:
527 proportional to efficiency, and randomly rounded. Was missed in
529 * Don't permit bombing of embarked planes and land units.
530 * Fix capital maintenance to charge at 60% efficiency.
531 * launch command now requires only 40% plane efficiency, for
532 consistency with other ways to launch missiles.
533 * Disable collateral damage when automatically launched missiles miss
534 their target. Collateral damage was done even when the launch
535 failed or the missile got intercepted. It's been disabled for
536 manually launched missiles since 4.0.18, for the same reason.
537 * Fix a bug that corrupted the lostitems file. Broken in 4.3.12.
538 * Show command changes:
539 - Move product information from "show sect c" into new "show
540 product", and reformat it to be easier to understand.
541 - New column navigability in "show sect s".
542 - "show sect s" now shows the packing bonus type instead of
543 selected packing bonuses. "show item" shows the actual bonuses
545 - "show sect b" now shows the usual values in addition to unusual
547 * Fix interdiction to obey op-area for missiles.
548 * Fix a bug that caused a stale sources.mk to be distributed in the
549 4.3.14 an 4.3.15 tarballs. The latter does not build out of the
551 * Don't strip tab characters from quoted command arguments. Broken
553 * shutdown commands now always take effect immediately. Before, they
554 could be delayed by up to a minute.
555 * shutdown could start multiple shutdown threads when you initiated a
556 shutdown shortly after cancelling one. This screwed up the timing
558 * Deity syntax of zdone changed, and is now documented in info.
559 * The threshold command could be tricked into accepting negative
561 * Fix designate to always write updated bmap to disk.
562 * Fix bomb to fail on empty <pin|strat> argument instead of flying
564 * Fix a bug in distribute that screwed up the current sector's
565 distribution center when the command got aborted.
566 * Commands arm, bomb, deliver, drop, fire, fly, paradrop, recon,
567 lmine, order, power, range, sail, shutdown, sweep and tend did not
568 honor command abortion at some prompts.
569 * Fix a bug in handling of EOF from client that could bite in the
571 - EOF at target prompts for bombing commodities, ships, planes and
572 land units sent the server into an infinite loop that ate all
574 - EOF at sail's path prompt crashed the server.
575 - EOF at some prompts in deliver, designate, fly, morale, zdone,
576 attack and assault didn't abort the command.
578 * Selector terr is now the same as terr0 for mortal players, and
579 dterr for deities. This matches how the territory command works.
580 Unfortunately, this required us to rename xdump sect field terr to
581 terr0. Sorry about that.
582 * Fix bomb not to let you bomb dead ships and land units.
583 * Make the retreat command a bit more helpful on retreat conditions,
584 and make it fail on bad conditions.
585 * Fix the mapper scripts. Broken in 4.2.0.
586 * Fix flying commands not to let planes do double duty as escorts.
588 * When a minesweeper hit a mine after sweeping, the mine wasn't used
589 up. If it sank the minesweeper, the code accessed freed memory,
590 which could clobber the ship file or worse. Broken in 4.0.17.
591 * Don't let non-light units board ships that can't carry them.
592 * Capitals can now employ up to 1000 civilians instead of 999.
593 * Spy command changes:
594 - Spy now requires sector military. Before, presence of land units
595 was sufficient, but spies shot were only deduced from sector
596 military. If you lost more spies than you had sector military,
597 the rest came back from the dead.
598 - Spy no longer ignores non-sea sectors without civilians, military
600 - Remove columns lnd, pln from spy report. The values didn't match
601 the reported land units and planes, and could leak the presence
603 - Establish contact when spy succeeds even though the spy was
605 * Fix news reporting and damage when land units interdict ships in
606 sectors other than sea.
607 * Fix land unit return fire damage to ships to take accuracy into
608 account, like the fire command and interdiction does.
609 * Remove the inconsistent shelling damage reduction for range. Fire
610 command got damage reduced by 10-20% with a chance depending on
611 range ("Wind deflects shells"). Ships interdicting got it reduced
612 by half. Other ways to shell did not get damage reduced for range.
613 * Fix ground combat to report defending land units. Broken in 4.3.4.
614 * Info file and documentation fixes and improvements.
616 Changes to Empire 4.3.15 - Sun May 18 08:59:30 UTC 2008
617 * The edit command keys deprecated in 4.3.10 are now gone.
618 * fairland now obeys game file locks.
619 * Do not leak world creation time in files utility, because that
620 facilitates attacks against fairland's PRNG. Broken in 4.3.12.
621 * Fix starvation not to starve one more than it should. The last man
622 on a boat or land unit now can't starve anymore.
623 * Fix a crash bug in satellite. Broken in 4.2.7 and not fixed
625 * Fix a coordinate normalization bug that could theoretically lead to
626 buffer overruns and other unpleasantness. None have been
627 reproduced, though. Broken in 4.3.12.
628 * Remove option FUEL. The abstract idea of tying ships and land
629 units to a logistical tether is sound, the concrete implementation
630 as option FUEL is flawed. It adds too much busy-work to the game
631 to be enjoyable. It hasn't been enabled in a public game for
632 years. The code implementing it is ugly, repetitive, and a burden
633 to maintain. The edit command still accepts and ignores the fuel
634 keys for compatibility, but they are deprecated.
635 * Fix pin-bomb not to report subs when there are none.
636 * You now have to take a capital to capture the victim's money, loans
637 or market lots. Merely obliterating the capital doesn't cut it.
638 It still makes the victim lose money, though.
639 * Fix a bug that could theoretically allow sacking of non-existant
640 capitals of visitors, deities and such.
641 * You now gain BTUs and MOB_ACCESS mobility before the first update
642 again. You didn't since 4.3.10 introduced the ETU clock.
643 * Fix edit to detect when the edited object changes while it's being
645 * Fix xdump nat for relations: it got HIDDEN backwards. Broken in
647 * Fix origin command not to prompt twice for its argument. Broken in
649 * Info file improvements.
651 Changes to Empire 4.3.14 - Mon May 5 04:57:03 UTC 2008
652 * Another round of fixes to the fire command:
653 - Don't disclose where the target retreated to.
654 - Charge the target shells for returning fire.
655 - Always use guns when the target is out of range, even if it's a
656 submarine. Before, the difference in shell use disclosed whether
657 the target is a submarine. Loophole opened in 4.3.12.
658 - Make depth charges again work with just one shell. Failing the
659 command in that case lets players find out whether the target is
660 a submarine. Loophole opened in 4.3.12.
661 - Detect when the firing sector, ship or land unit changes across
662 the target prompt. Abusable.
663 * Fix parsing of anchor-relative time in update schedule. Broken in
665 * Fix logging of player input in the journal to include command
666 interruption and EOF.
667 * Fix oversights in 4.3.12's change to keep track of flying planes:
668 planes could be erroneously reported damaged by their own ground
669 strikes. Happened with missions and the launch command.
670 * Fix load not load hardened missiles.
671 * Fix harden not to harden missiles loaded on land units.
672 * New server option -E to choose what to do on recoverable internal
673 error. You can now make the server dump core and keep going (not
674 implemented for Windows). New econfig key post_crash_dump_hook to
675 run a program after crash-dumping. See scripts/savecore for an
677 * Journal entries are now flushed to disk right away even when the
678 server is not running in debug mode.
679 * Don't let land units load trains.
680 * Allow deity to display power report for all types of countries,
682 * Fix designate's check for disallowed sector types. Broken in
684 * Documentation fixes.
686 Changes to Empire 4.3.13 - Tue Apr 15 19:03:11 UTC 2008
687 * Work around strptime() lossage on some systems. Fixes the parsing
688 of the schedule file there.
689 * New selector maxnoc for xdump version.
690 * Fix initialization of realms in newcap. Broken in 4.3.12.
691 * Fix add for status arguments active, god, delete. Broken in
693 * Info file, manual page and documentation fixes.
695 Changes to Empire 4.3.12 - Wed Apr 2 05:35:06 UTC 2008
696 * Fix rounding error in update that could result in more babies than
697 food permits, and negative food.
698 * Fix a bug that could lead to unfair thread scheduling under
700 * Fix ship and land unit missile interdiction and ballistic missile
701 interception to require a proper base. Before, missiles could
702 launch from anywhere for that.
704 - Don't allow launching from unowned sectors.
705 - Don't destroy missiles stuck on foreign ships.
706 - Use up the supplies required for launching an asat only when it
708 - Don't ignore satellites' fuel use.
709 * Deity command newcap now requires its second argument (sanctuary
710 coordinates). Before, it tried to pick a suitable location when
711 none was given. The code implementing this feature had problems,
712 and it's not worth fixing, because it is obscure, and rarely (if
713 ever) used: no conscientious deity would use it for a real game,
714 and for blitzes fairland does a better job.
715 * Keep track of flying planes properly. This fixes a number of bugs:
716 - While the bomb command awaited pin-bombing target input from the
717 player, other players could interact with the pin-bombers and
718 escorts as if they were sitting in their bases: spy them, damage,
719 capture, load, unload, or upgrade them, even get intercepted by
720 them. But any changes to those planes were wiped out when they
722 - The bomb command could bomb its own escorts, directly (pin-bomb
723 planes) or through collateral damage, strategic sector damage,
724 collapsing bridges or nuke damage. The damage to the escorts was
725 wiped out when they landed.
726 - If you asked for a plane to fly both in the primary mission and
727 escort, you got charged fuel for two sorties instead of one.
728 * Plug memory leaks in plane interception.
729 * Fix trade not to let the buyer teleport satellites (not in orbit)
730 and asats to an arbitrary sector. Abusable, because abms
731 intercepted from anywhere, and satellites could be launched from
733 * The PRNG seed is now logged in the journal.
734 * Fix nightly build for Windows.
735 * Fix crash bug that bit when custom tables contained columns names
736 that existed, but weren't supposed to be in the custom table.
737 * New timestamp selector for commodity, country, game, loan, nation,
738 news, realm, trade, treaty to support incremental xdump.
739 * Deity commands newcap and add wipe the nation more thoroughly. add
740 no longer touches relations and flags for status active and god.
741 * New utility program empdump to export and import game state as
742 plain text. Check its manual for details, including limitations.
743 * Plane, ship and land unit stats are no longer stored as game state,
744 but recomputed from tech and base stats as needed.
745 * xdump ver is no longer a special case. Syntax "xdump ver" is now
746 deprecated. Use "xdump version *".
747 * Fire and torpedo cleanup and bug hunt:
748 - Plug memory leak in fire command.
749 - Fix ammunition use when returning fire: resupply could lose
750 shells when returning fire to multiple targets, and land units
751 were charged per target instead of just once.
752 - Interdicting land units now resupply shells automatically, for
753 consistency with other ways to fire.
754 - torpedo and fire no longer resupply shells automatically. The
755 latter used to resupply land units only.
756 - Land units no longer have to be in supply to fire actively, for
757 consistency with other ways to fire.
758 - Submarines with zero mobility can no longer interdict, for
759 consistency with other ways to torpedo.
760 - Fix bugs that let submarines without capability torp use
761 torpedoes to return fire and interdict.
762 - Fix torpedo command not to require a line of sight for return
763 fire and depth charges, and to use torpedo range instead of
764 firing range for return torpedoes.
765 - Active fire and interdiction didn't work for ships with zero
766 firing range, even though return fire and support did. No such
767 ships exist in the stock game.
768 - Let land units with zero firing range and non-zero firing damage
769 fire, for consistency with ships. No such units exist in the
771 - Ships required different numbers of military to operate their
772 guns for the various kinds of fire. Unify to require 2*N-1
773 military to fire N guns.
774 - Ship ammunition use differed for the various kinds of fire.
775 Unify to use one shell per two guns.
776 - Forts could fire support even when there were not enough mil.
777 - Fix automatic shell resupply in several places to supply exactly
778 the shells actually fired, no more, no less.
779 * Change depth charges back to how they are documented and worked
780 before 4.0.6, mostly: require no guns, one military, do damage like
781 shell fire from three guns (before 4.0.6: two guns), use two
782 shells. In 4.0.6's model, they worked exactly like shell fire
783 (require guns and gun crew, non-zero firing range, damage and
784 ammunition use scales with available guns), except for missions,
785 which was a bug. Note that depth charge damage for all ships is
786 now like fire from three guns for two shells. No change for dd; af
787 did two gun damage for one shell before, and nas did four gun
788 damage for two shells.
789 * The edit command keys deprecated in 4.3.3 are now gone.
790 * Fix build not to screw up automatic dependencies on certain compile
792 * Fix a bug that could prevent repeated news from properly
793 aggregating into one news item.
794 * Properly initialize all bits in game state files, even those that
796 * Fix explore's test for stopping on a splashed bridge. The bug made
797 explore print to a bogus message.
798 * Fix spelling of symbol airburst in table plane-flags. This could
800 * Change designate not to check total cost before executing the
801 redesignation. The code implementing that was buggy and too ugly
802 to live. Designate doesn't cost anything in the stock game.
803 * Always charge land units at least as much mobility for assaulting
804 from non-landing ships as from landing ships. Before, marines lost
805 all mobility when assaulting from a non-landing ship, which could
806 be less than what the same assault costs from a landing ship (half
808 * Fix LWP's stack initialization for -s. It caused crashes on some
810 * Fix confused and buggy bridge splashing code:
811 - Flying planes could be reported drowned.
812 - Pin-bombing a bridge head failed to collapse bridge spans for
813 lack of support, unless the pin-bombing caused collateral damage.
814 - Corrupt sector file could lead to infinite recursion.
815 * Relative names now work for econfig keys data and info.
816 * Fix utility programs to abort on internal errors. They used to
817 print a message and attempt to recover.
818 * Fix off-by-one in fairland that ate the last expansion island.
819 * Switch from CVS to git.
820 * Code refactoring and cleanup.
822 * Info file, manual page and documentation fixes and updates.
824 Changes to Empire 4.3.11 - Tue Jan 1 18:57:38 UTC 2008
825 * New sector selector elev. It's set by fairland, but has no effect
826 on the game. It can be useful for deities to customize a world
828 * The client now copes with ids greater than 15. The Empire
829 protocol currently uses 14 ids.
830 * Rewrite the client's code for reading server output during login.
831 The old code could write one byte beyond the end of the buffer
832 (theoretically a remote hole), got confused by long lines, and
833 lines that didn't arrive in one piece.
834 * Long country name, password or user name crashed the client.
835 * Fix xdump not to deny access to game state tables when maximum
836 minutes per day are exceeded.
837 * The server considers a country bankrupt when its treasury is
838 negative. Except when it doesn't. Fix that:
839 - report misreported countries with $0 as broke.
840 - If a command spent a few cents more than you had, commands requiring
841 money became unavailable even when rounding brought you back to
842 $0. But logging out and back in then bankrupted you.
843 - If your treasury rose to exactly $0, commands requiring money
844 remained unavailable.
845 - If you had $0, sectors didn't build and sectors and ships didn't
846 produce at the update.
847 * Fix a bug in trade that made your money evaporate when a trade fell
848 through because you couldn't fully pay. This bug was there since
849 the introduction of the market in 4.0.0. It got aggravated by the
850 removal of forced loans in 4.3.0.
851 * Fix printing of the new group in army, fleet and wing. Broken in
853 * Fix flash not to screw up the message when the first argument
854 contains white-space.
855 * Don't let planes intercept when they are stuck in foreign bases, on
856 inefficient ships or land units, or on land units loaded on ships
858 * Fix a bug that made interception require petrol to be present even
859 for planes that don't use fuel (SAMs). Broken in 4.3.3. Air
860 defense missions weren't affected.
861 * fairland and setsector now limit fertility to 100 instead of 120,
862 like the other resources.
863 * Generalize the autonav hack for fishing boats so it covers oil
865 * Fix bug in path command that made it swallow every other step.
867 * The execute command no longer supports redirections and execute in
868 batch files. Flaws in the Empire protocol make it next to
869 impossible for clients to implement that correctly. See
870 doc/clients-howto for an explanation.
871 * Rewrite much of the client's code for sending commands and
872 receiving server output:
873 - No longer blocks on sending commands, which could deadlock the
875 - Fix race condition that could cause server output to be discarded
876 on EOF on standard input.
877 - Don't discard server output when reading standard input fails.
878 - Fix error handling for execute and other, more obscure cases.
879 - More rigorous error checking for redirections and execute.
880 Clearer error messages, too.
881 - Fix execute redirected to file or pipe. Believed to be broken in
883 - The client now creates files for redirections with the same
884 permissions whether the redirection is in a pipe or not. Before,
885 redirections without a pipe created files with no permissions for
886 group and others. This change may make your redirected output
887 visible to other users on your system. Use the usual controls,
888 like umask, to restrict permissions to your liking.
889 - Reject unexpected redirections (violating the protocol). Before,
890 they silently replaced the current one, and in the case of pipes
891 leaked file descriptors and memory.
892 - Redirections in batch files are not implemented. They didn't
893 quite work before, and could leak memory and file descriptors. A
894 flaw in the Empire protocol makes them next to impossible to
896 - The execute command in batch files is not implemented. A flaw in
897 the Empire protocol makes this practically useless anyway.
898 - Old code leaked memory in various places.
899 - Unfortunate incompatibility with older servers: if you type the
900 EOF character (normally ^D) at an argument prompt, the session
901 hangs. Use the interrupt character (normally ^C) to get out.
902 * The client now supports options -h and -v.
903 * The client no longer zaps its command line in a lame attempt at
904 protecting users who foolishly specify passwords on the command
905 line. Zapping annoys system administrators and creates a false
907 * Journal entries are now flushed to disk right away when the server
908 is running in debug mode.
909 * Fix bugs in load that could make loading operations fail noisily
910 instead of silently on some systems.
911 * Server now reliably shuts down session when it receives an
912 end-of-file condition from the client. Before, it merely failed
913 the current command when it got it at an argument prompt.
914 * Fix bug in execute that could crash the server on some systems when
915 it prompts for the argument.
916 * Fix bug that let you check whether a non-allied carrier is
917 efficient enough for takeoff when one of your planes got stuck
919 * Fix bug that let you attempt to escort a one-way mission to a
920 carrier with non-light, non-interceptor escorts. Such planes don't
921 fit on carriers, and the command then failed with a bogus error
922 message. Before 4.2.17, the planes flew, and the escorts were
924 * Change the rules for fitting planes on ships slightly, so that the
925 order of loading no longer matters. Choppers and x-lights can now
926 use plane slots even when not light. X-light choppers, which don't
927 exist in the stock game, can no longer use x-light slots.
928 * The server now keeps its log file open, just like the journal.
929 * New server option -R to set the PRNG seed. This is for
930 reproducible tests. Change the Windows-only service uninstall
931 options from -r/-R to -u/-U.
932 * Supply a real PRNG for Windows instead of the leaky water-pistol
934 * Threads sleeping until a specified time could return early under
935 Windows. This could cause missed updates. Broken in 4.3.10.
936 * Fix missing newline in show updates.
937 * Power report didn't factor tech into power correctly. Broken in
939 * Code refactoring and cleanup.
940 * Info file and documentation fixes and updates.
942 Changes to Empire 4.3.10 - Thu Sep 6 17:59:53 UTC 2007
943 * Bridge spans now cost $1000 instead of $2000, and bridge towers
944 $3000 instead of $7500.
945 * The Windows port now supports IPv6, but it still needs to be
946 enabled manually at compile-time.
947 * The custom table reader detects more errors.
948 * Do not leak world creation time in files and fairland, because
949 that facilitates attacks against the PRNG. This misfeature crept
951 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
952 Using it required manual hackery since 4.3.0.
953 * Plug file descriptor leak in add command.
954 * Don't kill player connections violently when their thread appears
955 to be hung. Threads being aborted by update or shutdown could be
956 misidentified as hung, and the violence could lead to resource
957 leaks, locked out updates, and corrupted game state.
958 * Fix LWP to reliably wake up threads sleeping for a time. Before,
959 players with a sufficiently fast connection could starve out system
960 threads, including the update.
961 * Fix a class of bugs that made commands behave differently while the
962 update is attempting to take control:
963 - No MOB_ACCESS mobility was gained.
964 - Telegrams were miscounted.
965 - Bulletins got misfiled as production reports.
966 - The navigate command ignored sail paths.
967 - The declare command was more quiet, and declarations of war
968 failed silently when SLOW_WAR was enabled.
969 - Many messages got misdirected to bulletins.
970 Some of these bugs go back all the way to Empire 2, ca 1995.
971 * New deity command reload, effect similar to SIGHUP.
972 * Not voting for a demand update no longer lets you veto further
973 demand updates. This feature was flawed (it encourages players to
974 vote late so that they can tactically vote no and thus build up
975 veto rights), virtually unused, and buggy. The edit command still
976 accepts and ignores the country key 'U' for compatibility, but it
978 * Fix zdone not to claim to have triggered an update when they're
980 * New update scheduler and ETU clock:
981 - New schedule file. See doc/schedule for how to use it. Replaces
982 econfig keys update_policy, adj_update, update_times, hourslop,
983 blitz_time. A change of schedule does not require a server
985 - The force command can no longer force updates in the future.
986 Edit the schedule file for that.
987 - New command show updates to show the update schedule. Obsoletes
989 - New xdump game and xdump updates.
990 - New utility program empsched to help test update schedules.
991 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
992 by econfig key update_demand.
993 - econfig key update_demandtimes no longer applies to scheduled
995 - You now receive new BTUs at the update in addition to login.
996 - You now always gain the same BTUs and MOB_ACCESS mobility per
997 turn, even when the update schedule changes, updates get missed,
998 or unscheduled demand updates run.
999 - Remove the mobupdate command, because porting it to the new ETU
1000 clock is not worth it.
1001 * Redesign of synchronization between commands, update and shutdown,
1002 and how updates are triggered:
1003 - Simplify update to a single thread waiting for the trigger.
1004 Before, three update threads had to perform a carefully
1005 choreographed dance to make updates happen. The dance relied on
1006 thread priorities for correctness, which are only implemented by
1007 LWP. With pthreads and under Windows, demand updates were prone
1008 to two update threads starting up concurrently. Even with LWP,
1009 forced and demand updates could lead to double updates.
1010 - Use a lock for synchronization: commands take it shared, update
1011 and shutdown take it exclusive. This makes update and shutdown
1012 block until all aborted commands terminated and gave up their
1013 lock. Before, they proceeded blindly after waiting two or one
1014 seconds respectively, which was cheesy and unsafe.
1015 - New commands no longer fail while the update is pending, they are
1016 delayed until after the update.
1017 - New commands can no longer start during shutdown. Before, they
1018 could, but risked getting killed violently, possibly corrupting
1020 - Fix command execution so that commands blocked in writing
1021 redirections are abortable. The bug allowed players to delay
1022 update and shutdown indefinitely.
1023 - Fix shutdown not to let player threads block on output. This
1024 let players delay shutdown indefinitely.
1025 - Fix reading of player input not to block again after update or
1026 shutdown aborted it. The bug allowed players to delay update and
1027 shutdown indefinitely.
1028 * Thread priorities are only implemented by LWP and no longer used.
1029 With LWP, they let players with a sufficiently fast connection
1030 starve out the threads that clean the lost file and kill idle
1031 connections. Drop them.
1032 * Show nuke rounded required research incorrectly.
1033 * Log unprintable characters as octal escapes rather than question
1034 marks in the journal file.
1035 * The files program no longer changes permissions of existing files.
1036 * The files program now creates all files with permissions ug=rw and
1037 all directories ug=rwx, modified by umask.
1038 * Fix a bug that could make arm, disarm and nuke detonation work with
1039 a used-up nuke instead of the armed one. This could be abused to
1040 detonate nukes multiple times. Broken in 4.3.3.
1041 * Fix nuke detonation output for zero blast radius.
1042 * Plug memory leaks in thread code.
1043 * Fix a bug that made LWP I/O wakeup unreliable.
1044 * New march sub-command v for view.
1045 * Journal was initialized before threads were, which was wrong.
1046 * Fix server not to create a journal on SIGHUP when it is disabled.
1047 * shutdown 0 now requests immediate shutdown instead of cancellation
1048 of a pending shutdown. shutdown -1 now cancels.
1049 * flash and wall no longer split long message lines.
1050 * Fix a bug in collect that screwed up a fully collected loan instead
1051 of deleting it. The screwed up loan could not be sharked or
1052 collected, but it could be repaid.
1053 * Remove the wait command, it's been broken and restricted to deity
1054 since Empire 2, ca. 1995.
1055 * Budget failed to take sector production into account for predicting
1056 unit repairs. Before 4.3.6, this bug bit only when you fooled
1057 around with budget priorities.
1058 * When unit repairs are limited by materials, the efficiency gain is
1060 * Ship repairs outside harbors and plane repairs by carriers used to
1061 consume commodities when and as far as available. Now, they
1062 consume the same fraction of the real cost of each commodity,
1063 i.e. commodity use is limited by the most scarce commodity.
1064 Neither old nor new behavior make much sense, but the new code is
1066 * Code refactoring and cleanup, in particular to make the Windows
1068 * Portability fixes.
1069 * Info file and manual page updates. All manual pages are now
1070 installed in section 6.
1072 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
1073 * Fix declare to prevent the deity from changing relations for a
1074 player to self. Allow the deity to set the relations of a player
1076 * Fix arm not to put the same nuke on multiple planes (broken in
1078 * New option AUTO_POWER.
1079 * Sectors now repair allied land units.
1080 * Sectors now repair only own and allied planes.
1081 * Fix repair of planes on foreign carriers: repair allied planes,
1082 ignore the others. Before 4.3.3, carriers destroyed rather than
1083 repaired foreign planes. Since 4.3.3, foreign planes were treated
1084 as recoverable error.
1085 * Fix automatic fortification of land units to use all excess
1086 mobility even when mobility delta exceeds mobility maximum.
1087 * Disable automatic fortification of land units when MOB_ACCESS is
1088 on, because it is prohibitively slow then (broken in 4.2.13).
1089 * Budget now shows level production (tech, education, research and
1090 happiness) rounded instead of randomly rounded.
1091 * Fix update not to randomly flush small level production to zero.
1092 * Fix overly restrictive game file locking under Windows (broken in
1094 * Fix navigate to charge mobility for sweeping mines without moving
1098 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
1099 * Ships no longer produce stuff when the government is broke.
1100 * Fix land unit casualties in revolts.
1101 * Fix security units not to raid friendly che.
1102 * Fix update sequence to ensure stopped sectors don't work on the
1103 ships, planes and land units in the sector. Before 4.3.6, this bug
1104 bit only when you fooled around with budget priorities.
1105 * Fix canal loading (was broken in 4.3.0).
1106 * Fix tend not to tend land units that could not be loaded.
1107 * Make xdump command available before break, but deny access to game
1109 * Lock game files to prevent concurrent access by multiple programs.
1110 fairland does not yet obey the lock.
1111 * Fix production to consider sector item limit.
1112 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
1113 * Enhanced mapping sub-commands in move, test, explore and transport.
1117 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
1118 * Sanctuaries are again fully populated with civilians (4.3.6 changed
1119 the limit, but not the population). Food is now spread evenly
1121 * Fix path finder to find shortest naval and aerial paths again
1123 * transport's map sub-command now does the right thing for a unit
1125 * Fix bug in map sub-command of move, explore and transport that
1126 passed junk to map command. Could theoretically crash.
1127 * Food need reported by starvation was one short for sectors without
1129 * Change land unit ammunition use back to what it was before 4.2.3.
1130 This lets deities customize ammunition use independent of damage.
1131 It also substantially reduces ammunition consumption at high tech.
1132 * navigation and march enhancements:
1133 - Sub-command 'f' now takes an optional ship / land unit number.
1134 - Mapping sub-commands now take an optional ship / land unit
1136 - New sub-command 'd' to drop mines.
1137 * Let minesweepers retreat at their full speed (missed in 4.3.6).
1138 * SUPER_BARS cannot be harmed, so don't interdict them.
1139 * Don't let trains and non-trains march together for now, because the
1140 march code isn't prepared for that.
1141 * New mapping flag 'n' to show nukes.
1142 * Mapping flag '*' now shows nukes as well.
1143 * New command nbmap to bmap around a nuke. Overload command nmap to
1144 map around a nuke when given a nuke argument.
1145 * Fix an inconsistency that gave tactical bombers a small bonus
1146 vs. flak when pin-bombing.
1147 * Fix production to show the designation that actually produces, not
1148 the designation as it is now (broken in 4.3.6).
1149 * Fix accidental whitespace change in output of sdump, pdump and
1150 ldump that crept into 4.3.5.
1151 * Support user-defined sector types and products in custom tables,
1152 not just customization of existing ones.
1153 * Fix off-by-one bug in budget that used to be masked by budget
1154 priorities until their demise in 4.3.6. The bug could crash the
1155 game on certain systems.
1159 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
1160 * The shutdown command now terminates the server process correctly
1161 even with LinuxThreads pthreads under Linux 2.4 and earlier.
1162 * Cope with old versions of groff (broken in 4.3.0).
1163 * You can now arm allied planes with nukes.
1164 * Taking a nuke off a plane gives it to the sector owner again.
1165 Feature was accidentally dropped in 4.3.3. Recipient must be
1167 * Naval path went bananas for impassable end sectors (broken in
1169 * New econfig key disabled_commands.
1170 * New territory selector dterr, restricted to deities. The territory
1171 command defaults to it for deities.
1172 * Let land units attack as long as they have positive mobility,
1173 except for high-mobility terrain (mountains), where the rules
1174 remain as they were: land units need to have all the mobility
1175 charged for the attack, not counting combat and moving in to
1176 occupy. Rationale: Making sure your land units reach attack
1177 positions with enough mobility left is a pain in the neck.
1178 Requiring only positive mobility is friendlier, but allowed rushing
1179 of mountains, so we make an exception there.
1180 * Can typeset info pages as PostScript. Result isn't exactly pretty.
1181 * Support disabling of infrastructure in infra custom table. Remove
1182 redundant option DEFENSE_INFRA. show command now shows only enabled
1184 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
1185 pmap sbmap, smap (broken in 4.3.1).
1186 * New, simpler sector mobility cost formula:
1187 - The basic cost is still a linear function of sector efficiency,
1188 with customizable cost at 0% and at 100%. The latter used to be
1189 derived from the former. The show command shows both parameters
1191 - Mountains are no longer a special case.
1192 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
1193 to 1.304, highway, bridge head, bridge span and bridge tower
1194 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
1195 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
1196 players can designate now cost the same at 0%. That's a feature.
1197 - Road infrastructure now reduces cost up to 90%, linear in road
1198 efficiency (used to be close to that, but non-linear). Same for
1199 rail infrastructure, but 99%. Adapted from Ice World V.
1200 - Double land unit minimum cost to 0.02, to slow them down on
1202 - Change land unit cost penalty in newly taken land to an extra 0.2
1203 instead of a minimum of 0.2, to reduce penetration depth.
1204 * Reduce bridge head defense and collect value to match highway's.
1205 * sinfrastructure displayed bogus rail mobility costs when there was
1207 * Retreating engineers took full landmine damage instead of half.
1208 * Fix socket creation code not to print a null pointer.
1209 * Fix login option code not to search beyond end of table (broken in
1211 * Spy planes and satellites can no longer spot landspies.
1212 * Spy planes can now spot surface ships at sea. They can no longer
1213 spot land units loaded on ships or land units.
1214 * Fix train retreat mobility cost, and don't permit retreat off rail.
1215 * Change maximum population to 100 for plains (was 49), mountains
1216 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
1217 the other habitable sector types (was 999).
1218 * Let minesweepers navigate at the speed their stats indicate by
1219 letting them sweep on the move at no extra mobility charge.
1220 * Reduce chance for planes to abort from 100-eff (if eff<80) to
1221 80-eff. This should make it easier to punch through air defense,
1222 flak in particular, and increase the risk of getting shot down.
1223 * Ship and land unit flak intensity is now proportional to efficiency.
1224 * Ship and land unit flak intensity is no longer scaled by the tech
1225 of the owner of the last thing firing. It's still scaled by each
1227 * All ships and land units firing flak now spot the plane and are
1228 spotted by the plane. Previously, spotting stopped as soon as flak
1230 * Inefficient land units were overcharged mobility when reacting.
1231 Broken when Empire3 changed land unit mobility use not to depend on
1232 efficiency, except for supply units.
1233 * New journal file to log complete player input plus selected
1234 important events. Controlled by new econfig key keep_journal, off
1236 * Fix unsafe shutdown on SIGINT and SIGTERM.
1237 * Fix land unit path finding: paths weren't always cheapest (broken
1238 in 4.0.2), and trains could be sent down paths without rail (never
1239 worked). Also fixes unit reaction path cost.
1240 * The custom table reader can now deal with sector, item, product and
1241 infra tables more comfortably.
1242 * Remove option BIG_CITY. Deities can customize the sect table to
1243 get the same effect.
1244 * Many more selectors can now be compared with names, not just
1245 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
1246 not fully work for queer names like &&&.
1247 * Let land units on missions support, just like ships.
1248 * Don't let units loaded on a train react.
1249 * Change update sequence to repair ships, planes and land units after
1250 sectors produce. This makes repairs use new avail instead of old.
1251 * Let players stop and start units.
1252 * Remove budget priorities.
1253 * Make plane report easier to understand.
1254 * Change land report to show carriers in the same format as plane and
1257 * Info file and manual page fixes.
1259 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
1260 * In conditionals, ~ compared to a string selector now stands for an
1262 * Change encoding of `not in any group' from " " to "". This makes
1263 fleet=~ work. It also affects xdump.
1264 * Fix plane capture code to clear wing.
1265 * People now eat and starve exactly the same in sectors, ships and
1266 land units. There used to be small differences, and civilians and
1267 uw loaded on land units didn't eat at all. The starvation command
1268 has been updated accordingly.
1269 * Fix bug that makes it impossible to assault or board with land
1270 units (broken in 4.3.4).
1273 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
1274 * Don't use non-portable groff features (broken in 4.3.0).
1275 * Work around potential crash bugs in command argument access.
1276 * Plug major information leak through nation selectors (broken in
1277 4.2.21). The fix unfortunately exchanges the meaning of xdump
1278 nation and xdump country. Sorry about that.
1279 * Minimize redundancy between (mortal's) xdump nation and xdump
1281 * New nation selector rejects.
1282 * xdump nation now shows foreign relations and no longer discloses
1284 * Fix crash bug in edit.
1285 * Fix number of planes building in budget command (broken in 4.3.3).
1286 * Selectors group, fleet, wing and army are now strings, and obvious
1287 syntax like fleet#a works. xdump also shows the strings now.
1288 Units not assigned to a group currently have group string " ", but
1289 that may still change.
1290 * Don't fold conditionals to lower case, because it breaks valid
1291 conditionals like fleet#A.
1292 * Mobility cost of a plane sortie is no longer limited to current
1294 * Various formulas no longer truncate or round intermediate results.
1295 * Interdiction mission charged twice the normal mobility cost for
1297 * Fix sail not to interpret negative x-coordinates as unsail
1299 * Improved configure script.
1302 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
1303 * power c can now show powerless countries. power c * works.
1304 * Fortresses now require 5% efficiency to return fire and interdict.
1305 * Range of ship return fire and support fire no longer depends on
1307 * Fix heap smash in login command client. Remote hole!
1308 * Properly destroy nukes on collapsing bridges. Before, you could
1309 rescue them by building a new bridge or arming them on naval
1311 * Nukes are now numbered like other units:
1312 - New selector type replaces selectors number and types.
1313 - New selector plane points to plane armed with this nuke.
1314 - New selectors effic, mobil, tech, group, opx, opy, mission,
1315 radius. Provided because all units have them; values are
1316 currently not interesting.
1317 - nuke command output redesigned.
1318 - ndump output changed subtly: nukes are no longer sorted by
1319 location, nukes in the same location no longer share id, and
1320 nukes on planes are shown.
1321 - transport nuke now works like transport plane.
1322 * arm and disarm now accept the common plane syntax, not just plane
1324 * Fix arm to let you change an armed plane's air-burst/ground-burst
1326 * territory no longer re-prompts when supplied with a bad argument,
1328 * edit lets you edit stuff that is actually computed from other
1329 state, like sector's coastal flag. This makes no sense and is now
1330 deprecated. Stuff deprecated since 4.2.15 is now gone.
1333 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
1334 * Fix security units' raid at the update (broken in 4.0.0, fixed only
1335 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
1336 increase. Make sure empty units don't kill anyone.
1337 * Fix bug in player_init(), which was most likely fatal on 64 bit
1338 hosts. Broken in 4.3.0.
1339 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
1340 * The order in which sectors were visited for `*' arguments disclosed
1341 the real origin, fix. Mapping commands used to work around this
1342 bug, until 4.3.1 exposed it there as well.
1343 * Code didn't compile on some systems.
1344 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
1346 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
1347 * Fix check of game state on server startup (new in 4.3.0).
1348 * sail now accepts a destination sector.
1349 * Tend could send bogus bulletins (broken in 4.3.0).
1350 * Plug memory leaks in mission command.
1351 * Close loophole in navigate that allowed players to find all sectors
1352 that are unfriendly or inefficient harbors or bridges.
1353 * Server didn't start when default econfig was missing and user
1354 didn't supply one with -e (broken in 4.3.0).
1355 * Retreat condition 'h' (helpless) never worked, fix.
1356 * Fix retreating mine sweepers to use mobility for sweeping.
1357 * Fix retreating land units to hit mines with the same probability
1358 and to take the same damage as in normal movement. Before,
1359 hit probability was higher, and damage was lower.
1360 * Ships could retreat into sectors owned by whoever made them
1361 retreat, but not in their owner's sectors.
1362 * Fix 'm' at the movement prompt of transport and test.
1363 * Fix march and test not to apply conditionals to sectors mapped,
1364 which led to spurious error messages.
1365 * Fix break not to respect conditionals. The bug let players keep
1367 * Fix retreat code not to respect conditionals. Attackers could
1368 abuse this to suppress fleet and army retreat orders.
1369 * Fix retreat and edit to zero-terminate retreat paths.
1370 Theoretically abusable for gaining information.
1371 * Fix format string crash bugs in load, spy and bomb.
1372 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
1373 ~p before the first line of text never worked.
1374 * Fix ancient bridge building race condition that could break the
1375 test whether the player can afford the bridge.
1376 * Fix trade lot change detection in set command. Probably abusable.
1377 * The pthread code now compiles under Solaris.
1378 * navigate and march now permit any whitespace between route and
1379 optional argument for radar, lookout, sonar, not just spaces.
1380 * Fix canal navigation (was broken in 4.3.0).
1383 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
1384 * version no longer pretends option SHIPNAMES still exists.
1385 * Remove files auth and ban. They could be used to restrict client
1386 address and user. Restricting user is useless, because players can
1387 send whatever they want. Banning IPs is better done with a packet
1388 filter. That leaves restricting deity IPs. Provide new econfig
1389 key privip for that. Apply it to session kill as well as login.
1390 * xdump escapes GUINEA_PIGS status:
1391 - xdump is now enabled unconditionally.
1392 - xdump sect now dumps selector coastal, because it can't be
1393 reliably computed from other xdump information.
1394 - New xdump realm and country. Realm information is now stored in
1395 a separate file, with appropriate selectors.
1396 - Reviewed for completeness and information leaks. See info xdump
1397 for remaining issues. New treaty selector uid, nat selectors
1398 relations, contacts. Removed useless selectors: news and lost
1400 - Command syntax changed.
1401 - xdump opt is no more, option information is now in xdump ver.
1402 - xdump can now dump meta-data.
1403 - Header and footer changed to be more compact. You now need
1404 meta-data to identify fields.
1406 - Documentation in doc/xdump.
1407 * New econfig key builtindir.
1408 * New econfig key custom_tables lets you customize configuration
1409 tables without recompiling. Customizing tables other than unit
1410 tables is not recommended for now. See doc/econfig for
1412 * Check configuration and game state are sane on server startup.
1413 * Remove option NONUKES and NEUTRON. Deities can load a suitable
1414 nuke table to get the same effect.
1415 * Remove option DRNUKE. Use econfig key drnuke_const to control
1416 whether nukes need research.
1417 * Disqualify land units from performing missions while loaded on
1419 * Fix dump for strings without terminating zero.
1420 * Fix login command option not to send an extra prompt.
1421 * zdone now displays information about demand update vetoing.
1422 * The Windows port now requires Winsock version 2.
1423 * Remove econfig key powe_cost.
1424 * version report now shows all the configurable settings of interest
1426 * carg and lcarg now display people as well.
1427 * ldump now dumps civ and uw as well.
1428 * Fix dangling pointer dereference in dogfighting code.
1429 * Tell sector owner when partisans take over. But don't disclose che
1431 * emp_server, files, fairland now support options -h and -v.
1432 * Simplify baroque version numbering to a single version number.
1433 This affects output of version.
1434 * New show item and show news.
1435 * New build process:
1436 - Follow the usual steps: configure; make; make install. The
1437 latter is optional. The only file deities still have to edit is
1439 - Use GNU Autoconf for system configuration.
1440 - Use GNU Make for portability and features.
1441 - Support separate build trees.
1442 - Remake out-of-date dependencies automatically.
1443 - Remake out-of-date info files automatically.
1444 - Flatten info directory.
1445 - Formatted info files are no longer distributed in source tarball.
1446 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
1447 low-level options doesn't seem to be worth the effort, as
1448 UCONTEXT should be pretty portable.
1449 * Fix use of freed memory in sail.
1450 * sail could let large ships enter big cities.
1451 * Fix reject and accept not to require contact.
1452 * Fix sharebmap and telegram to prompt for a missing first argument.
1453 * Fix report to align column research correctly for deities.
1454 * When the optional newspaper argument doesn't work because HIDDEN is
1455 enabled, complain instead of ignoring it silently.
1456 * When BLITZ is enabled, fairland no longer permutes country numbers
1457 in newcap_script so that start islands are ordered from top left to
1459 * Minimize output format differences between options:
1460 - census shows column fall regardless of FALLOUT.
1461 - show nuke now shows column res regardless of DRNUKE.
1462 - report no longer suppress column status when HIDDEN is enabled.
1463 HIDDEN limits status information like for the country command.
1464 - relations column width differed depending on option SLOW_WAR.
1465 Always use the wider format.
1466 * Fix a bug in edit that suppressed the player notification telex on
1467 military reserve change.
1468 * Fix command dispatch not to let deities use commands that are
1469 declared not to be available to them. The only command affected is
1471 * Fix the list command for visitor.
1472 * econfig key m_m_p_d no longer applies to deities.
1473 * Fix the origin command for country #0. Allow moving origin to
1474 another country's origin. Allow deities to reset origin to
1475 absolute 0,0. This turns origin into a superset of the offset
1476 command. Remove offset command.
1477 * Fix a bug that caused unpredictable flak damage when it should have
1478 been maximum damage (was broken in 4.2.19).
1479 * Don't store initial capital location, remove the associated nat
1480 selectors xstart, ystart.
1481 * Fix production command to consider resource depletion.
1482 * Fix justification of coordinate output in cutoff and mission.
1483 * Option UPDATESCHED is no longer optional. Disabling it didn't
1486 * Turn options into ordinary econfig keys.
1487 * New econfig key start_cash.
1488 * BTU regeneration now depends on the capital's work percentage.
1489 * nation now supports an optional argument that lets deities ask for
1490 somebody else's nation report.
1491 * Fix nation to display SANCTUARY instead of VISITOR for countries in
1493 * Fix capital to let you use a regained sacked capital without
1494 activating another one in between.
1495 * Don't move capital when it is sacked.
1496 * New ship capability canal, replacing obscure formula based on build
1498 * You now need a capital to request a demand update.
1499 * power now ignores landspies.
1500 * Fix LWP stack checking.
1501 * Clean up LWP, drop dead machine-specific code, fix portability bugs
1503 * census now shows the old owner instead of `*'. dump is unchanged
1504 to avoid breaking clients.
1505 * peek no longer prints the old owner.
1506 * When a bombed land unit retreated, collateral damage was applied to
1508 * paradrop, drop and fly can no longer abandon the base sector.
1509 * Tending foreign ships now sends a bulletin to the owner.
1510 * Fix bug that permitted login for inactive countries, including ""
1511 * Fix tend for spies.
1512 * Change launch to fire all missiles selected at the same target.
1513 Previously, it prompted for a new target after each missile.
1514 * add, consider, build, launch and fire no longer re-prompt when
1515 supplied with a bad argument, they just fail. Consequently, the
1516 build command no longer lets you list types you can build. It
1517 points to the show command instead.
1518 * Fix add not to truncate country number.
1519 * Fix selector coastal to be accurate at all times.
1520 * Fix obscure bug in fairland: the sector added last to an island
1521 wasn't considered coastal. Affected resource computation.
1522 * Fix sector wiping in add command.
1523 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
1524 ways. Custom configuration tables should become a serviceable
1525 replacement eventually.
1526 * Client no longer freezes on long lines of server output.
1527 * Fix uninitialized signal mask bugs.
1528 * Fix Windows service code's treatment of -e.
1529 * Sub interdiction disclosed sub owner through news' actor selector.
1530 * country reports on all countries, but carefully limits information
1531 disclosed to mortals. Output format changed.
1532 * Market no longer forces sellers to grant loans.
1533 * Fix potential crash bug in set command. Friendlier prompt and
1535 * Substantial code cleanup and portability fixes.
1536 * Extend empfile abstraction to cover game configuration.
1537 * Overhaul of game state storage.
1538 * The above includes major contributions from Ron Koenderink. Many
1541 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
1542 * Make version pretend option SHIPNAMES still exists, for the benefit
1543 of clients that still depend on it.
1544 * The change to conv in 4.2.22 could crash or compute incorrect
1546 * Info updates missing in 4.2.22.
1547 * A few code cleanups.
1549 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
1550 * Log player login, logout and session kill.
1551 * Close loophole in assembly point rules that allowed players to find
1552 all unowned sectors. The assembly point must now be owned by you
1553 or an ally, or you or an ally must have a ship there.
1554 * Don't let embarked land units fire flak.
1555 * Fix display of the last connection's host when the host name was
1557 * Fix change command to accept full length representative (password),
1558 currently 19 characters. It used to chop off after eight
1560 * Non-recon missions no longer establish contact to owners of
1561 overflown sectors, because those missions do not identify the
1562 owner. This matches info Hidden.
1563 * The following events now establish contact:
1565 - Sighting a ship when toggle coastwatch is off
1566 - Spotting overflying planes
1567 - satellite spotting land units
1568 - lookout and llookout spotting ships, planes and land units
1569 - Any relations change
1570 * The country command's `temporary' state of disorder ended after
1572 * Telegram notifications could get lost in exotic circumstances,
1573 e.g. while a second client attempted to connect. Abusable.
1574 * Remove option SNEAK_ATTACK.
1575 * Fix lboard not to let you board dead land units.
1576 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
1578 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
1580 * Fix fly to let the player abort the command at the last prompt.
1581 * Client no longer reads execute scripts in binary mode under
1583 * New econfig key listen_address.
1584 * econfig key port can now be a service name. Service empire no
1585 longer takes precedence over econfig.
1586 * Client falls back to compiled-in host only if environment doesn't
1587 supply one, not if it can't be resolved. Same for port.
1588 * Oil derrick could extract slightly more oil than was in the ground.
1589 * test command checked start sector for space and some other things
1590 instead of end sector.
1591 * convert now silently limits conversions to avoid exceeding maximum
1593 * shoot no longer limits you to 999 victims.
1594 * 4.2.19 broke pin-bombing commodities on some platforms.
1595 * Don't block on output while update is pending. This is required to
1596 ensure the update can abort commands.
1597 * Commands submitted while the update is waiting for commands to
1599 * The force command no longer waits for the specified time. It
1600 starts a scheduling thread instead, just like shutdown.
1601 * Correct grammar and punctuation in output of version.
1602 * Option SHIPNAMES is no longer optional.
1603 * Fix output of qorder and sorder for ships with sail path.
1604 * Don't change capital to agribusiness on retake. From Pat Loney.
1605 * bdes prompt for new designation was messed up for empty bmaps.
1606 * Client now supports pipes under Windows.
1607 * Care for subtle Windows socket incompatibilities.
1608 * Fix strength command not to lie about units reacting into
1610 * strength now yields the processor periodically, to keep the game
1612 * Schedule commands more fairly. Previously, a sufficiently fast
1613 player could starve out the others.
1614 * launch assumed plane maximum mobility 127 for calculating when
1615 satellites will be ready to use.
1616 * Drop support for for DCE threads.
1617 * Drop support for pthread implementations lacking pthread_kill().
1618 This includes ancient versions of OS X.
1620 * Minor info file fixes.
1621 * The above includes major contributions from Ron Koenderink. Many
1624 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
1625 * Don't let threads block on output to another player thread's
1626 socket. Such blocking violates basic design assumptions and can
1627 cause all kinds of grief. In particular, it causes player session
1628 hangs under Windows with 4.2.20. Broken since the introduction of
1629 flash and asynchronous telegram notification many years ago.
1630 * Threads sleeping until a specified time could return early under
1631 Windows. This could cause double-updates.
1632 * Fix fallout damage (was broken in 4.2.19).
1633 * Fix show sector s (was broken in 4.2.19).
1634 * Fix deliver not to deliver friendly civilians into occupied
1636 * Fix mil duplication in board (was broken in 4.2.14).
1637 * Fix stack smash in lrange, shoot and execute. Remote holes, and
1638 the last one doesn't even require authentication.
1639 * Fix crash bug in emp_config parsing.
1640 * Fix buffer overruns in turn and shutdown.
1641 * Fix second argument of shutdown.
1642 * announce, pray, telegram and turn now abort on EOF.
1643 * Fix display of MOTD and game down message of maximum size.
1644 * Correctly support telnet line termination on input. Previously,
1645 carriage returns could slip into ship names and such.
1646 * Fix flash not to lie about recipients that are just logging in.
1647 * Remove obscure login command list.
1648 * Convert client from obsolete termcap to terminfo, and clean up
1650 * New fairland option -h to print usage information. Improved
1651 command line syntax diagnostics. Exit unsuccessfully on unknown
1653 * fleet and army now copy retreat orders of the fleet's or army's
1654 first member with group retreat orders in the same sector.
1655 Previously, they used the retreat orders of the first fleet or army
1656 member, which is less than useful, and failed to take ownership
1657 into account, which is an abusable bug.
1659 * Fix xdump not to disclose other countries' losses.
1660 * Fix exit status of files program when it can't create files.
1661 * Support UTF-8 encoded Unicode in human-human communications. This
1662 affects MOTD, game down message, telexes, announcements and flash
1663 messages. See new doc/unicode for technical details.
1664 * New login command `options' for client/server option negotiation.
1665 See new doc/clients-howto for technical details. The only option
1667 * emp_client -u now requests UTF-8. This requires a terminal that
1669 * Fix news for land unit defensive support.
1670 * Properly mark sea mines hit by retreating ships. Unmark mines
1672 * Fix diagnostics for unknown selector names in conditionals (was
1674 * Fix selector name clashes: rename ship selector mobquota to mquota,
1675 land selector for reaction range limit from rad to rmax.
1676 * Fix Windows services for relative file names on command line or in
1677 econfig (was broken in 4.2.20).
1678 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
1679 are now float. This gives deities finer control over maximum
1681 * Fix production command for sectors with 60% efficiency.
1682 * Improve syntax of read for deities.
1684 * Some info topic names differed only in case, which loses on
1685 case-insensitive file systems, and is a bad user interface even
1686 when it works. Change those names. Rename deity command hidden to
1687 peek because its info topic clashed with that of option HIDDEN.
1688 * Thanks to Doug Wescott sheep are finally covered properly in info.
1689 * Documentation fixes.
1690 * Much of the above was contributed by Ron Koenderink. Many thanks!
1692 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
1693 * When units in different sectors marched, only units in the sector
1694 with the highest-numbered unit were interdicted. A marching
1695 non-spy made all marching spies visible to interdiction regardless
1697 * Fix crash when interdiction sinks second ship in a sector. Broken
1699 * Fix an ancient bug in simulation of level production that clobbered
1700 stack and could lead to low predictions, typically zero, which
1701 screwed up budget. The bug had no effect until 4.2.19.
1702 * When a sector revolts, and there wasn't enough space to liberate
1703 all uw, the number of remaining uw got the wrong sign. Broken in
1705 * Log and abort when LWP stack check detects stack smash. Server
1706 option -s no longer implies -p.
1707 * The native Windows build now supports -p and -s.
1708 * The native Windows build now properly deals with ^C when running in
1709 the foreground. It no longer prompts for a quit command on the
1711 * The meaning of server option -D in presence of -e is unclear.
1712 Other programs only support -e. Remove option -D. Use -e
1713 DIR/econfig instead of -D DIR.
1714 * New server option -v shows version information.
1715 * Fix the server's exit status with -h. Broken in 4.2.19.
1716 * The linux-pthreads build failed to shut down on signals.
1717 * Fix threading bugs in the native Windows build that made shutdown
1718 unsafe and screwed up update aborting commands.
1719 * New econfig key pre_update_hook to allow automatic, safe backup
1720 right before the update. See scripts/backup for an example.
1721 * The server now prints log messages to stderr as well when running
1723 * Fix potential buffer overflows in logerror() and lwpStatus().
1724 * Server now requires POSIX signals. It no longer catches SIGUSR1.
1725 * Remove support for ancient versions of HP-UX.
1726 * Fix seeding of PRNG broken in 4.2.19.
1727 * Don't reseed the PRNG in commands, it hurts randomness and could be
1728 abused by crafty players.
1729 * The server now makes the data directory its working directory.
1730 This also gets rid of a bug that changed the file name of the
1731 sector, power, nation and lostitems file unless econfig could not
1733 * The server now writes a pid file. Thanks to Daniel O'Connor.
1734 * More user friendly server startup: more errors are detected while
1735 the server still runs in the foreground, which makes it possible to
1736 complain to stderr and to exit unsuccessfully.
1737 * Early log messages went to the log file in the default data
1738 directory, even though econfig specifies another data directory.
1739 * Specifying an econfig file on the command line that can't be read
1741 * Errors in econfig are now fatal.
1742 * The server now refuses to start when it can't open data files.
1743 * News are now sorted and expire sanely.
1744 * Conditionals can now compare strings as well.
1745 * Corrupted down and motd files could cause buffer overflows.
1746 * Fix recon to let player abort at the flight path prompt.
1747 * power no longer rounds worldwide numbers for deities.
1748 * power command failed to recognize deities with non-zero country
1750 * Change output of production command so that columns are aligned
1751 even for large values. Replace column wkfc by more useful column
1753 * neweff and production miscalculated work when mil exceeded
1755 * neweff miscalculated work when the population limit exceeded 999.
1756 * Fix capping of avail when a big city is torn down.
1757 * Fix a bug in fire that allowed players to find all submarine uids.
1758 * Maximum sector population is no longer hardcoded, and now covered
1759 by xdump. Option RES_POP now affects mountains and plains as
1760 well. From Ray Hyatt.
1761 * Fix fina and news not to ignore errors in conditions.
1762 * The native Windows build now requires Windows Sockets 2.
1763 * The native Windows build now supports multiple instances of the
1764 service. The ability to supply additional startup parameters to
1765 the service has been removed.
1766 * Implement fairland command line parsing under Windows.
1767 * Improved fairland and emp_server usage message.
1769 * Minor info file and documentation fixes.
1770 * Much of the above was contributed by Ron Koenderink. Many thanks!
1772 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
1773 * Fix order not to unload into full sectors.
1774 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
1776 * Fix distribute not to conjure up a civilian when importing
1777 civilians from a dist center that doesn't have any.
1778 * Fix flak to resupply no more shells than actually needed.
1779 * Fix rounding error in shoot that could result in more people shot
1780 than actually there.
1781 * Fix info and apro error handling. In particular, do not leak
1782 potentially sensitive information on the server to players.
1783 * info no longer shows a random matching page when the topic argument
1784 is ambiguous. Instead, it lists all matching topics.
1785 * Embarked land units and overflying planes no longer spot each
1787 * Fix show command to show only sectors that players can designate
1788 (was broken in 4.2.18).
1789 * Fix a rounding error in production command column `max'.
1790 * Fix production command for overpopulated mountains and plains.
1791 * Fix tradeship ally cut to match documentation.
1792 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
1793 * Fix a bug in aerial sonar where ships could mask submarines with
1794 the same number modulo 256.
1795 * Don't allow bombing of subs that were not detected.
1796 * MOTD and the game down message are now entirely separate: use `turn
1797 motd' for the MOTD, and `turn on' and `turn off' for the game down
1798 message. `turn on' no longer lets you edit the MOTD.
1799 * Remove option NUKEFAILDETONATE.
1800 * Option ORBIT is no longer optional.
1801 * New option GUINEA_PIGS to control experimental stuff not ready for
1802 prime time. If your deity enables this in a serious game, run!
1803 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
1804 * New ship and land selectors rflags, rpath.
1805 * New ship selectors for order: xstart. xend, ystart, yend,
1806 cargostart, cargend, amtstart, amtend
1807 * New ship selectors for sail: mobquota, path, follow.
1808 * New news selector uid.
1809 * Implement command line parsing under Windows where it was missing.
1810 * emp_server and and files print a usage message on command line
1812 * Fix how emp_server exits after being panicked by a signal. It can
1813 now dump core when this happens.
1814 * Fix bug in client that could crash it when a line of input starts
1816 * Client now gets user name from environment variable LOGNAME if set,
1818 * The native Windows build can now run as a service.
1819 * Redirecting client input now works under Windows.
1821 * Don't confuse work with loyalty in info Citizens.
1822 * Minor info file and manual page fixes.
1823 * Much of the above was contributed by Ron Koenderink and Marc
1824 Olzheim. Many thanks!
1826 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
1827 * Fix info to accept abbreviated arguments under Windows. From Ron
1829 * Buying planes or land units loaded on something didn't work when
1830 that something moved.
1831 * Fix a bug that could produce update cascades with update policy
1833 * Fix delivery and distribution to grant packing bonus only to
1834 efficient sectors, just like move. Previously, delivery ignored
1835 efficiency, and distribution behaved as if it were an efficient
1836 sector without special bonuses.
1837 * New sector selectors loyal, access; ship selectors radius, access,
1838 xbuilt, ybuilt, builder, name; plane selectors radius, access,
1839 theta; land unit selectors radius, react, nland, access; lost
1841 * Fix sector selectors che, che_target; plane selectors att, def;
1842 nuke selector types; treaty selector exp; news selector time;
1843 commodity selectors type, xbuy, ybuy.
1844 * Option PLANENAMES is no longer optional.
1845 * Ensure config parameter variables and their description in
1846 configkeys[] are consistent. Inconsistencies there caused bugs in
1847 the past. From Marc Olzheim.
1848 * Complain if econfig file can't be read.
1849 * Better messages for errors in econfig file.
1850 * Remove unused econfig keys hard_tech and last_demand_update.
1851 * New econfig key news_keep_days to configure news expiry.
1852 * New econfig key anno_keep_days to configure announcement expiry.
1853 * Fix announcement expiry. It leaked file descriptors and memory,
1854 and could corrupt the anno file. From Ron Koenderink.
1855 * New command xdump: experimental extended dump. Disabled for now.
1856 * Bankers no longer round down debts, and they collect interest for
1857 the time debtors are idling at sub-prompts.
1858 * Loan interest calculation was broken at the due date and after a
1859 last payment made at the due date. With luck, debtors could abuse
1860 this to repay loans cheap (they couldn't gain cash, though), sharks
1861 to purchase loans cheap, and creditors to collect excessively.
1862 * Fix major bug in transport that allowed two cooperating countries
1864 * Don't report interdiction damage twice when transporting planes.
1865 * Fix message for attempting to transport a plane in a sector not
1866 owned by the player.
1867 * Fix confusing diagnostics when refusing to improve defense because
1868 option DEFENSE_INFRA is off.
1869 * Simplify confusing code in budget.
1870 * Fix spacing in output of budget and show.
1871 * Change one-way plane sorties to match ordinary sorties: offer
1872 carriers regardless of the sector they're in, require carriers to
1875 * Don't print owner of incoming missile twice when intercepting it.
1876 * Simplify constituent storage in product characteristics.
1877 * Replace remaining `variables' leftovers; mainly in unit
1879 * Remove leading spaces in deity unit dumps.
1880 * Replace inappropriate uses of compile time constant ETUS by 60.
1881 Deities don't change ETUS, they change etu_per_update by editing
1882 econfig. This nonsense dates back at least to chainsaw 3.31.
1883 * Change ship production (fishing and drilling for oil) to match
1884 sector production. Ship efficiency and tech are now relevant, and
1885 all people on board work. From Ron Koenderink.
1887 * Minor info file fixes.
1889 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
1890 * Fix seeding of PRNG under Windows. The bug made updates occur at
1891 a predictable time in the update window. From Ron Koenderink.
1892 * Close major loophole in drop that allowed players to determine
1893 whether an arbitrary sector is sea, allied land, or other land.
1894 * fly could fly civilians into occupied sectors. For consistency
1895 with other means to move around stuff, this is no longer possible.
1896 * Don't allow flying to a carrier that doesn't have space for the
1897 planes. Previously, planes that did this were teleported home,
1898 which could be abused.
1899 * Close loophole in bomb that allowed players to find all
1901 * Fix move and explore not to crash when moving civilians to a sector
1902 without civilians, and interdiction destroys them all. Found and
1903 debugged by Jeff Cotter.
1904 * Fix printing of messages entered with turn command. '%' characters
1905 could cause havoc, even crashes.
1906 * Use sector's actual maximum population to compute chance of plague
1907 outbreak. Previously, code used 9999 for big cities and 999 for
1908 other sectors, and info Plague said 999. This makes all crowded
1909 sectors equally vulnerable, even mountains, plains, and inefficient
1911 * Oil derricks no longer drill and deplete more oil than they can
1912 hold. From Ron Koenderink.
1913 * Version 4.2.15's coordinate and list parsing fixes reject trailing
1914 junk. That's too strict. Silently ignore trailing junk as long as
1915 it starts with whitespace.
1916 * Version 4.2.15's selector rewrite broke some type literals,
1917 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
1918 type literals to selectors.
1919 * Nightly build patches game to get repeatable PRNG results. From
1922 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
1923 * Previous version broke sector production when part of the work is
1924 used for sector construction. Fix courtesy Jeff Cotter.
1925 * Add rudimentary tests to nightly build. From Marc Olzheim.
1927 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
1928 * test command no longer asks whether to abandon the sector.
1929 * explore command could generate a bogus `lost' record when it
1930 regains an abandoned start sector.
1931 * edit command now properly updates stats when editing tech level of
1932 ships, planes or land units. A few of these stats can be edited
1933 separately, which doesn't make much sense, and is now deprecated.
1934 * edit command no longer accepts efficiency values that would destroy
1935 the edited unit. Deities can still delete units by setting the
1937 * upgrade command used to charge an amount of avail that didn't match
1938 info upgrade. Neither the implemented nor the documented amount
1939 made much sense. Change it to 15% of the full build cost. Rewrite
1941 * Commands upgrade and build could be off by one when reporting
1943 * upgrade command reported rounded cost but charged unrounded
1944 cost. Round cost of upgrade down to match behavior of build.
1945 * Upgrading planes now preserves range when it is less than the
1946 maximum range. It used to set it to the new maximum range.
1947 * show bridge and show tower no longer claim bridge building requires
1948 `workers' (whatever that is), since it doesn't.
1949 * Replace option ROLLOVER_AVAIL by econfig parameter
1950 rollover_avail_max, which is the maximum amount of avail that rolls
1951 over. Previously, avail was limited after rollover, and even when
1952 ROLLOVER_AVAIL was off. Fix that.
1953 * Ships weren't always charged mobility for firing with option
1955 * Fix shell use of return torpedoes.
1956 * designate no longer complains twice about deity only designations.
1957 * Ensure designate zaps efficiency only when sector type really
1959 * Fix strength to always report mines to deities.
1960 * Remove option SHIP_DECAY.
1961 * Fix bug in sonar that could crash or yield unpredictable results
1962 near the true origin.
1963 * Fix buffer overflow in flash and wall.
1964 * Fix wall not to strip out first word of message.
1965 * Change market and order to use item types instead of mnemo
1966 characters internally.
1967 * Market now reports sales with full item names instead of single
1969 * buy now requires first argument to be an item name, as documented.
1970 * production command handled production backlog incorrectly, failed
1971 to limit production for production efficiency greater than one,
1972 e.g. agribusiness, and incorrectly limited raw material
1973 consumption. Also fix a rounding error. With help from Ron
1975 * Sector work was accidentally truncated to even.
1976 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
1977 don't divide SHRT_MAX+1.
1978 * Properly diagnose over-long unit lists.
1979 * Rewrite selector code. Old code let players smash the stack by
1980 supplying too many conditions. New code properly rejects ambiguous
1981 abbreviations and prefers exact matches. Selectors with names that
1982 collide with types, like land units' rad and spy, now work.
1983 Selectors with non-integral values, like land units' att, now work.
1984 * survey used to display hundreds for everything but variables. Now
1985 it displays hundreds only for values that can be large.
1986 * Rewrite info survey. Document ability to survey properties other
1987 than items and resources.
1988 * Rewrite info build, since it was inaccurate and poorly structured.
1989 * Fix info fire on required military. From Marc Olzheim.
1990 * New fairland argument -R to set the PRNG seed. Print the seed.
1991 This allows you to recreate the same world again.
1992 * New facilities to deal with internal errors. These crash when the
1993 server is started with -d, which is appropriate for debugging, and
1994 potentially disastrous for running a real game.
1995 * Automated nightly builds.
1998 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
1999 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
2000 * Gripe about unknown options in econfig.
2001 * Remove option GRAB_THINGS.
2002 * Utility program files takes new option -f.
2003 * Remove utility programs land, ore and perfect, which don't compile
2004 since 4.2.0 (Oct '98).
2005 * fairland no longer warns when it added resources, but when it
2007 * Fallout code could claim destruction of more items than actually
2009 * Fix recursive resupply (resupply from supply land unit triggering a
2010 resupply of the land unit) when just testing for how much can be
2011 resupplied. The bug could have led to insufficient resupply.
2012 * Fix recursive resupply not to consume all fuel in supply units. No
2013 supply units consuming fuel exist in the stock game.
2014 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
2015 Distribution threshold were previously limited to 10000, and
2016 delivery thresholds to 65528.
2017 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
2018 used to limit to 9990. Market transactions and commands explore,
2019 move, drop and fly to 32767. Limiting in autonav code (order
2020 command) didn't work. Item delivery used to stop at 9990,
2021 distribution at 9999. Food growing and sector production used to
2022 stop at 9999. Grind, assault lunchboxes, demobilization, mine
2023 sweeping and che liberating uw could theoretically attempt to
2024 increase items beyond 65535, which would have been ignored
2025 (destroying the increase).
2026 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
2027 fallout increases behaved inconsistently. Increases beyond 65535
2028 could get ignored, or fallout could saturate at 9999, or it could
2029 overflow at 65536 (that would take quite some nuking, though).
2030 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
2031 operation that would have gone beyond 65535 was ignored.
2032 * Fix `are we loading or unloading' tests for load, unload, lload and
2034 * Fix editing of land unit attack and defense values. Implement
2035 editing of ship defense values. Contributed by Ron Koenderink.
2036 * edit now edits che number and target separately.
2037 * Fix edit to properly extend unit files. Contributed by Ron
2039 * Major internal reorganisation: Sectors need space for items,
2040 deliveries and distribution thresholds. To save space, the
2041 ancients invented `variables': a collection of key-value pairs,
2042 missing means zero value, space for `enough' keys. This
2043 complicates the code, as assigning to a `variable' can fail for
2044 lack of space. Over time, `enough' increased, and for quite some
2045 time now `variables' have been *wasting* space. Replace them,
2046 except in unit characteristics, where they are read-only, and will
2047 be replaced later. This also removes misfeatures like plague
2048 outbreaks silently deleting deliveries.
2049 * Remove disabled commands dissolve and mult. Remove configuration
2050 parameters minmult and maxmult.
2051 * trade command indexed an array out of bounds when attempting to
2052 display the plague as commodity. Fix.
2053 * New make goal interix. Contributed by Ron Koenderink.
2054 * The type selector now prefers an exact match to a partial match.
2055 ?type=sb now selects sb, not sbc, even when sbc happens to be found
2057 * Value of selector sell was always zero, remove it.
2058 * Clean up selector code.
2059 * satellite now displays all sectors owned by other players, and none
2060 else. It used to display all but sea, mountains, sanctuaries,
2061 wasteland and wilderness.
2062 * map commands now display wilderness and plains owned by other
2063 players as '?'. Radar commands now display all wilderness and
2065 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
2066 * Make client abort the current command on ^C under Windows, as
2067 everywhere else. Contributed by Ron Koenderink.
2068 * Command line parser interpreted trailing whitespace as an another
2069 (empty) argument. Ignore it instead.
2070 * Properly declare stuff in headers, include proper system headers.
2071 Remove all nested external declarations. Source code is now fully
2072 prototyped. Enable appropriate gcc warnings.
2073 * Fix several type errors. Some may have been show-stoppers on big
2074 endian machines where sizeof(long) != sizeof(int).
2075 * Remove pre-ISO C compatibility cruft (hey, it's been only fifteen
2077 * Various portability fixes. Some bugs may have been show-stoppers
2078 when sizeof(long) != sizeof(int). With help from Marc Olzheim and
2080 * Move some code to more logical places. Remove some unused code,
2081 some of which was hard to port.
2082 * The files program could print error messages to a log file in some
2083 circumstances. Make it print to stderr.
2084 * deliver can now change direction without changing the threshold.
2085 * deliver now provides appropriate context when prompting for
2087 * Login command play no longer ignores up to two arguments if there
2089 * Fix payoff (was broken in 4.2.13).
2090 * Capability fish didn't work together with capability oil.
2091 * Fix and clarify plague outbreak chance in info Plague.
2092 * Fix RES_POP maximum population in info Research.
2093 * Fix info telegram and info announce on ~ escapes.
2094 * Update info Selector to match code.
2095 * Document all undocumented unit capabilities and stats.
2096 * Document submarines' ability to carry landspies.
2097 * Fix info shoot on security units.
2098 * Various small info file fixes.
2099 * Many fixes in the troff macro package for info files.
2100 * Many fixes for translating info files to HTML.
2101 * Many info file markup fixes.
2103 Changes to Empire 4.2.13 - Fri Feb 13 22:12:36 UTC 2004
2104 * Source code reindented and cleaned up somewhat.
2105 * Various small info file fixes.
2106 * Fixed change requiring 254 BTUs even when not charging any
2108 * Fixed tactical non-marine missile crash.
2109 * Fixed spy unit detection chance for eff<100.
2110 * Fixed output of sorder.
2111 * `edit' can now work non-interactively. Contributed by Ron
2113 * Fixed and extended edit for sectors.
2114 * Fixed use of errno.
2115 * Minor security fix: doconfig now writes example auth entry as
2117 * Fixed reading of country name and password in client for Windows.
2118 * Replace use of some obsolete non-portable library functions by
2119 portable equivalents.
2120 * designate now warns about redesignated capital only when it
2121 succeeds in redesignating the capital.
2122 * attack could be off by one when reporting required unit mobility.
2123 * Fixed command matching. Unique prefixes were not always
2124 recognized, and junk suffixes were ignored.
2125 * Removed bestdistpath. bestpath yields the same results.
2126 * Renamed lstats to lstat for consistency and to match info page.
2127 * Fixed non-portable fd_set * arguments of select().
2128 * New `map' flag `h' to highlight own sectors. Contributed by Marc
2130 * Fixed `sabo' reporting damage to player in deity coordinates.
2131 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
2132 * Fix Windows server shutdown on reading "quit" from stdin.
2133 * Land units now fortify automatically when mobility plus growth
2134 exceeds the maximum. With code from Marc Olzheim.
2135 * Wandering che are less predictable.
2136 * Land units no longer regenerate mobility faster while it is
2138 * Fixed emp_client -k.
2139 * No longer allow pirates to ferret out where a ship was built.
2140 * Fixed map commands to reject bmap flags `t' and `r' instead of
2142 * Fixed lmine shell resupply.
2143 * News no longer call all sub-launched missiles nuclear.
2144 * Incoming missiles are now reported with coordinates.
2145 * Removed some code that served no purpose except crashing on
2147 * Fixed Mac OSX and AIX build problems.
2148 * Don't resolve player IP addresses for now, because it can crash
2149 with certain versions of GNU libc.
2150 * Fixed recording of lost nukes.
2152 Changes to Empire 4.2.12 - Mon Aug 18 16:54:21 MDT 2003
2153 * Corrected contact information for Wolfpack.
2154 * Sector isn't abandoned until move or explore is complete.
2155 * Fixed multiple cases where return value of getstarg() was
2156 used without being checked which crashed the server.
2157 * Used stdarg.h instead of varargs.h.
2158 * Call only_subs and save result before mission frees attacker
2159 list. Call with free list could cause server crash.
2160 * Fixed spy sat map for units on opposite side of world wrap.
2161 * Don't sleep in main thread when called from signal handler.
2162 * Fixed error checking in pthreads.
2163 * Properly detach pthreads.
2164 * Pass unlocked mutex to pthread_mutex_unlock.
2165 * Cope with interrupted sleep in pthread empth_sleep to prevent
2167 * Added server configurable update window.
2168 * Initialized variables passed to setsockopt in accept.c.
2169 * Fixed bug where sharing bmap with uncontacted country crashes
2172 Changes to Empire 4.2.11 - Sun Sep 1 09:54:59 MDT 2002
2173 * Added compile option for the Mac OSX architecture.
2174 * Fixed bug in cargo where unit array was indexed by shp_maxno
2175 instead of lnd_maxno.
2176 * Fixed bug in reject where aborting the command crashes the
2178 * Can't buy land units into enemy headquarters.
2179 * Added sabotage command and commando unit.
2180 * Spies moving by themselves will not trigger interdiction.
2181 * Fixed error in map distance calculation that caused errant
2183 * Ships going under -127 mobility will be set to -127 mob and
2184 not roll over to positive mobility.
2185 * Corrected plane cost in info Maintenance.
2186 * Changed error message for loans rejected for being too big.
2187 * Land units will take casualty damage proportional to their
2188 ability to carry mil.

2199 wouldn't be kicked off during long flashes or writing telegrams.
2200 * LOSE_CONTACT will work as advertised.
2201 * Allied units marching through 0 mobility conquered sectors
2202 are charged at least LND_MINMOBCOST.
2204 Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001
2205 * Assault can reinforce own sector when SLOW_WAR is enabled.
2206 * emp_client no longer converts lines into tags but still verifies executes,
2207 pipes, and file redirect match players input.
2208 * Added pboard command to capture enemy planes in your territory.
2209 * Declaring war when at Sitzkrieg won't return relations to Mobilizing.
2210 * Declaring war won't charge money if you're already Mobilizing.

2227 * Corrected formula for likelihood of plague in info Plague.
2228 * Fixed files to correctly size map and bmap files from econfig file.
2229 * No longer allowed to add country 0. It corrupts deity country.
2231 Changes to Empire 4.2.8 - Mon Oct 9 17:35:35 MDT 2000
2232 * Fixed range in radar.t and Sector-types.t. Maximum range at infinite
2234 * Changed so that player can't drop civilians into occupied sectors.
2235 * Fixed bug that crashes update if etus/update is less than 8.
2236 * Fixed sometimes not reporting overflights
2237 * Fixing flak for units/ships to be in all sectors as they should be
2238 * Updated order of firing flak in Flak.t.
2239 * Fixed 80% efficient planes on ships must be maintained.

2252 * Option MARKET is turned off by default.
2254 Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
2255 * Added new NF_SACKED flag to indicate when a country has had it's
2256 capital sacked. This flag is only cleared when the country actively
2257 redesignates it's capital using the "capital" command, and changed
2258 capital.t to reflect this (no more re-sacking after an update if the
2259 country doesn't reset and repeating until they are out of cash.)
2260 * Added land unit to edit command for planes.
2261 * Added nuketype to edit command for planes.
2262 * Changed so that if the leader of a group of units is a train, the
2263 railways are used for bestpath instead of roadways.
2264 * Changed mission command to also print reaction radius of reserve
2265 missions when set for land units.
2266 * Changed Flak.t to reflect guns having to be loaded onto a land unit
2268 * Changed so that visitor countries cannot change their name or password.
2269 * Changed so that you cannot upgrade deity planes, ships or units.
2270 * Changed so that you know where missions are flown from.
2271 * Changed so that the airport owner you fly a mission from is informed.
2272 * Changed so that preperations for takeoff are reported to the owner of
2273 the sector, ship or unit a plane is taking off from if it is not owned
2274 by the owner of the plane.
2275 * Changed so that when a sector reverts during a guerrilla revolt, the
2276 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
2277 you would always get at least an updates worth of mobility. With
2278 MOB_ACCESS, sectors that reverted during the update were useless, since you
2279 got no mobility for a long time. This fixes that problem, and makes che
2280 more useful as well.
2281 * Changed so that air defense missions don't always send up every plane in the
2282 area, but instead always send up at most two times the number of incoming
2283 planes (for each interdicting country.) This helps to stop 1 plane from
2284 stripping the mobility from 25 air defense planes all at once, but doesn't
2285 limit it to n+1 as there is for regular interception.
2286 * Clarified deity reversion of sectors in Sector-ownership.t
2287 * Clarified production efficiency and added pointer to "show sector cap"
2289 * Clarified nuketype selector for planes in Selector.t
2290 * Clarified that fortifying units does not affect mission status in info
2291 pages for mission and fortify.
2292 * Clarified fuel syntax upon error in fuel command in empmod.c.
2293 * Cleaned up comments causing minor complaints in some builds.
2294 * Fixed bug in loans where you could collect on proposed loans.
2295 * Fixed production command to be more accurate (though it *still* has some
2296 rounding errors, it's better.)
2297 * Fixed potential memory leak in air defense missions.
2298 * Fixed bug where you couldn't pinbomb some commodities if other commodities
2299 didn't already exist in the sector.
2300 * Fixed bug where you couldn't build 0 crew planes without military in the
2301 sector. (This is different from needing at least 1 military to build all
2302 planes that need a crew which introduced another related bug earlier.)
2303 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
2304 messages to be displayed for deity owned planes.
2305 * Fixed bug where land units on ships in a sector taken over were blown
2307 * Fixed bug where planes on ships in a sector taken over were blown up
2309 * Fixed bug in sdump printing origx and origy in deity coordinates.
2310 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
2312 * Fixed bug in launch showing wrong satellite target (showed asat instead
2313 of the target satellite.)
2314 * Fixed bug where you could gain information not normally available using
2315 the "fire" command to determine sector type information.
2316 * Fixed bug in market/trade creating extra money when loans are taken out.
2317 * Fixed problem with land units not being reported sunk after being sunk
2318 on a ship that was nuked or wastelanded in a sector.
2319 * Fixed problem with Spies.t using "llook" instead of "llookout".
2320 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
2321 on some Linux boxes.
2322 * Fixed problem with plague infection being way too high in cities when
2323 the BIG_CITY option is enabled.
2324 * Fixed bug in edit command getting confused with arguments.
2325 * Fixed bug in ask_move_in_off asking you to move in a negative number of
2326 troops (hey, it could happen. :) )
2327 * Fixed bug in add command not keeping flags or relations initially correct.
2328 * Fixed bug in torpedo command sometimes telling victim about torpedo
2329 sightings even when way out of range.
2330 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
2331 as not formatting them properly when reporting them.
2332 * Fixed bug in satellite with noisy transmission causing a potential
2333 crash of the server with non-100% efficient satellites.
2334 * Fixed potential crashing of the server during satellite display when not
2335 calculating distances to ships and units correctly.
2336 * Fixed bug where planes in non-allied sectors, ships and units could be
2338 * Fixed bug where planes on the trading block could be used on missions.
2339 * Fixed bug where planes and units that get traded don't have mobility set
2340 correctly when using MOB_ACCESS option.
2341 * Fixed bug which made security units virtually useless.
2342 * Fixed access times and mobility not being set right when building planes,
2343 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
2344 * Fixed minor formatting problem with launch of satellites.
2345 * Fixed minor formatting problem with planes with greater than 999 tech.
2346 * Fixed minor formatting problem with ships with greater than 999 tech.
2347 * Fixed problem with "llook" showing up in TOP info file.
2348 * Fixed problem with lwp Makefile choking on NT builds with clean target.
2349 * General cleanup of potentially ambiguous statements.
2351 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
2352 * Added "TECH_POP" as an option where technology costs more to make
2353 as your population grows past 50K civilians. It is disabled by
2355 * Changed "produce" command to accurately print what the true p.e. is.
2356 * Changed "update" command to display if mobility updating is enabled for
2358 * Fixed bug where toggling off the coastwatch flag also turned off
2359 forts firing on hostile ships coming into range.
2360 * Fixed bug where assaulting your own land would violate any treaties
2361 you have where assaults are a violation.
2362 * Fixed bug where all planes (even those without need for a crew, such
2363 as missiles) needed at least 1 military to build.
2364 * Fixed bug where when a ship sinks during the update due to lack of maint,
2365 land units and planes on it were left stranded.
2366 * Fixed bug where when a land unit dies during the update due to lack of
2367 maint, land units and planes on it were left stranded on it.
2368 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
2370 * Fixed bug in "show sector capabilities" not showing products correctly.
2371 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
2373 * Fixed bug in sectors that don't revolt not showing up as lost items.
2374 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
2375 * Fixed bug where MOB_ACCESS was not updating the mobility just before
2377 * Fixed bug in the way treaties are examined and sometimes produce
2379 * Fixed edit to allow creating negative mobility for sectors.
2380 * Fixed setsector to allow creating negative mobility for sectors.
2381 * Fixed bug where when writing out the value of a sector that had
2382 negative mobility and was damaged in combat, mobility was being
2384 * Fixed Taxes.t info page to reflect that captured civvies only pay
2386 * Fixed Technology.t info page to reflect TECH_POP option.
2387 * Fixed navigate.t info page to reflect that only ships in the fleet
2388 in the same sector that are fired upon have damage divided up.
2389 * Made techlists toggle on by default (so things are shown in order of
2390 technological advances.)
2392 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
2393 * Added optimization to increasing mobility to check if an object is
2394 already at max mob, just return since it can't be increased.
2395 * Added "-ltermcap" for client libs for hp build (it was already in
2397 * Added clearing of telegram flags after the update so that the next
2398 telegram is flagged as new and not part of the update.
2399 * Fixed Update-sequence.t to reflect MOB_ACCESS.
2400 * Fixed bug where fortification amount was not being limited to
2401 maximum mobility for land units (land_mob_max).
2402 * Fixed bug where land unit fortification strength was being calculated
2403 by using 127 instead of land_mob_max.
2404 * Fixed bug where scrapping land units was creating military.
2405 * Fixed description of sect_mob_neg_factor in econfig file.

2414 * Fixed potential bug in fixing up timestamp information when restarting a
2415 game with MOB_ACCESS turned on.
2416 * Fixed bug in explore command not setting mobility to correct
2417 value when MOB_ACCESS was enabled.
2418 * Fixed bug in enlist setting mobility incorrectly sometimes.
2419 * Added doc/backup file for deities which recommends how backups and
2420 restores of the data directory should be done.
2422 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
2423 * Added linux-pthreads target and build for using pthreads under Linux.
2424 * Added NO_FORT_FIRE option which disables the ability of forts to
2426 * Added more error checking and recovery for corrupt data files.
2427 * Changed alphapos target to alpha-pthreads for better clarity.
2428 * Changed fairland to allow 0 sector distance to other islands and
2429 continents (James Risner)
2430 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
2431 match the way ships are described (since this is how they really work.)
2432 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
2433 and "fir" as the number of guns that a land unit fires.
2434 * Cleaned up misc. build warnings.
2435 * Changed artillery damage to be 5 + d6 per gun firing from just d6
2436 per gun firing and updated Damage.t to reflect this change.
2437 * Changed artillery firing ranges to be like ships ranges - divided
2438 by two, and modified them to make more sense.
2439 * Changed artillery units to be "slightly" :) more powerful.
2440 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
2441 * Changed "artillery" unit to tech 35.
2442 * Changed so that guns are no longer required to build units, and
2443 that guns must be loaded onto artillery units for them to fire.
2444 Client developers note: the show command has not changed yet to
2445 remove the 'guns' column (since guns are no longer required) but
2446 will in a future revision (possibly 4.2.4) so "be prepared" for
2447 "show land build" to change. :)
2448 * Fixed landunitgun to handle all the damage calculations like it should.
2449 * Fixed bug sinking planes when the ship they are on sinks.
2450 * Fixed bug destroying planes when the land unit they are on is destroyed.
2451 * Fixed bug where land units could fire support without enough military.
2452 * Fixed bug in abandoning sectors by marching out a land unit where it
2453 would not let you sometimes (uninitialized variable problem.)
2454 * Fixed gets problem in files.c (James Risner)
2455 * Fixed bug in determinig operations range of a ship.
2456 * Fixed bug in building planes where you could manufacture military.
2457 * Fixed warnings in threading package(s).
2458 * Fixed fire.t to reflect new firing changes.
2459 * Fixed lstat.t to reflect new firing changes.
2460 * Fixed sstat.t to reflect the way things really work.
2461 * Fixed Ship-types.t to reflect the way things really work.
2462 * Fixed the way shutdowns work to hopefully better protect data files.
2463 * Fixed bug in attacking when sector mobility is less than 0 and it would
2464 prompt for attacking with a negative amount of military.
2465 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
2466 * Fixed bug in client when it prompts for country name it was putting
2467 an extraneous end of line on the end that needed to be stripped off.
2468 * Fixed problems running on Linux running on an Alpha machine. Thanks
2469 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
2470 on a machine to work out the bugs. (Note that the only build that
2471 works on Linux/Alpha is the linux-pthreads)
2473 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
2474 * Added some code optimizations into the update code when building paths.
2475 * Added some new cacheing for building paths to help speed up updates.
2476 * Added so that you can use "name" and "password" with the change command
2477 as well as "country" and "representative".
2478 * Added flag to power command so that if you are a deity and enter
2479 a negative number of countries you want to see, you see the power chart
2480 for that many countries without power numbers on the next line. Only
2481 useful for deities that want to see the chart un-broken up by that line.
2482 * Added new functionality to fortify command. You can now use a negative
2483 fortification value to cause the unit to be fortified and leave at
2484 least that much mobility on the unit. I.E. "fort * -67" will fortify
2485 all units and make sure the mobility of each unit doesn't go below
2486 67. If the mobility is already below that level (or equal) the unit
2488 * Added that the realm command prints "Realm #n is x:x,y:y" after
2489 you set a new realm.
2490 * Added TREATIES option and enabled it by default.
2491 * Added "no depth-charging subs" and "no new land units" treaty
2493 * Added Trannie Carter's basic client fix to use fgets instead of gets.
2494 * Changed market and command to only print the lowest priced lot of
2495 each given commodity by default. If you specify "all" it shows
2496 all lots on the market, and if you specify a specific item, it shows
2497 all lots of that item type.
2498 * Changed start command to only write out sector if it changed.
2499 * Changed stop command to only write out sector if it changed.
2500 * Changed how plane names were changed on server startup if the
2501 PLANENAMES option was enabled.
2502 * Changed move command to use standard askyn function for abandoning
2504 * Changed plane overlight sightings to take stealth into account,
2505 and if the planes managed to evade all flak and interceptors, they
2506 are not marked as "spotted" over enemy sectors.
2507 * Changed all units with the supply flag to have their marching speeds
2508 based on efficiency since that is their purpose. What this means is
2509 that supply units and trains are more effective at 100% than at 10%
2510 (just as fighting units are more effective at 100% than at 10%, but
2511 their effectiveness is determined by how well they fight, not how well
2512 they "run away, run away!" :) )
2513 * Changed so that flash toggle is on by default for POGO at setup
2515 * Changed so that when a sector is taken, all land units owned by the
2516 current owner are treated as planes are during takeovers (i.e. there
2517 is a pretty good chance they are blown up, and if not, they change owner
2518 to the attacker and are beat up pretty good.)
2519 * Fixed treaties to work again.
2520 * Fixed bug in taking over land units not using correct pointer (can
2521 cause a crash or data corruption.)
2522 * Fixed collect command to wipe deliver and distribution information
2524 * Fixed potential bug in bmap not working when destination bmap has
2526 * Fixed bug in shark command not getting right nation structure.
2527 * Fixed bug in server where empty commands (for example, all spaces
2528 or tabs) were being reported as bogus commands. They are now just
2530 * Fixed bug in scrap not dropping land units off of scrapped units carrying
2532 * Fixed bug in news where boarding of land units was reported backwards.
2533 * Fixed bug in calculating new people when growing them during an update.
2534 * Fixed missing -ltermcap in HP/UX build.
2535 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
2536 later and being reset to 0 anyway)
2537 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
2538 since that is what it really is.
2539 * Fixed retreat.t documentation to reflect the "retreat upon failed
2541 * Fixed bug where satellites were not orbiting the world during the
2543 * Fixed bug in torpedos being too smart. They knew how to jump over
2544 land! :) Now the "line_of_sight" routine is used to determine if a
2545 torpedo has a straight path to the destination. If it doesn't, the
2546 torpedo no longer jumps over land, but instead slams into it. This was
2547 an interesting bug because you could torp ships on the other side of
2548 a very skinny island as long as they were in range, even if there was
2549 no sea route possible.
2550 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
2551 units for example) but you still have to pick something to bomb. For
2552 ships it worked ok (just aborted that it couldn't find any more ships)
2553 and this was fixed for land units and planes.
2554 * Fixed server crashing bug when flying a plane and not carrying
2556 * Fixed bug in move losing commodities when it runs out of room in the
2557 destination sector. Goods are now attempted to be returned to the
2558 start sector, and apporpriate steps taken if the start sector is no
2560 * Fixed march to prompt you before you abandon a sector you own by
2561 marching out the last land unit.
2562 * Fixed check functions to only check the relevant portions of the structure
2563 and not the timestamp info that doesn't affect how the object functions.
2564 * Fixed bug in spy command that always told you if a spy unit was in a
2566 * Fixed bug in displaying of land unit missions not showing correct land
2568 * Fixed bug in wire command where new announcements that you read at
2569 the last second don't get wiped out properly.
2570 * Fixed bug where announcement file could be corrupted by very long lines.
2571 * Fixed bug where bmap was not set when player was told what kind of
2572 sector they were attacking (this was an old abusable bug that was
2573 removed long ago to fix the abuse, and it's been fixed in a non-abusable
2575 * Fixed bug where change command would warn you about monetary and
2576 BTU costs, but not prompt you to break out if you didn't want to really
2577 change your country name.
2578 * Fixed bug in sub-launched nukes that are intercepted being reported in
2579 the news incorrectly.
2580 * Fixed bug in load where you could abandon a sector and not know it by
2581 loading your last civilians or military onto a ship.
2582 * Fixed potential memory leak in autonav code.
2583 * Fixed potential bug where you could possibly determine if a sector is
2584 owned or not using one way plane missions.
2585 * Fixed Damage.t info page to properly show damages for planes and
2587 * Fixed deliver.t to include syntax for command.
2588 * Fixed country.t to include syntax for command.
2589 * Fixed bug where ships on orders were not adding radar information to
2590 the bmap during an update.
2591 * Fixed bug where ships on sail were not adding radar information to
2592 the bmap during an update.
2593 * Fixed bestownedpath code to use the bmap properly. Note this is a very
2594 important bug fix. When navigating a ship, players are no longer given
2595 free information that they would not normally know. For example, if you
2596 try sailing your ship off into uncharted areas of your bmap, the bestpath
2597 code will only use as much information as you have on-hand (i.e. your
2598 bmap) to plan out your path for you. If you have no information on an
2599 area, it just keeps forging on, until bumping into something. Of course,
2600 after the initial exploration through an area, the bmap will be set and
2601 used for all future sailings through that area. Harbors and bridges
2602 are still checked for construction worthiness if you know where they
2603 are (i.e. they are on your bmap.) (Overall, what happened before
2604 was that the bestpath code would route your ship around islands that
2605 you didn't even know were there, and you could use various commands
2606 to see how that ship was going to sail during the update and thus you
2607 gained information that you wouldn't normally know.)
2608 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
2609 and "BestAirPath" to use it properly. It is also good to note that
2610 bestownedpath is used to determine paths for ships and for planes,
2611 and that best_path (which uses the A* algorithm) is used for all land
2612 based paths, and that the two are never interchanged.
2613 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
2614 and RECON was never used before.)
2615 * Removed extraneous "resnoise" and "resbenefit" functions and combined
2616 the two for setresource and setsector commands.
2618 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
2619 * Fixed problem with global/plane.c not defining last structure element
2620 properly, and thus causing crashes when accessing certain plane
2621 routines. This happened during the move to make the PLANENAMES option
2622 run-time configurable.
2624 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
2625 * Bumped rev to 4.2.0 since this is a major release (the server is now
2626 run-time configurable for just about everything and is released under
2628 * Put in official licensing information.
2629 * Re-arranged and commented the econfig (Empire Configuration) file. The
2630 auto-generated "data/econfig" file is now pumped out chock full of
2631 comments (which may or may not be useful.) Since the server is
2632 pretty much fully run-time configurable (MAXNOC is not, but it gets
2633 a default of 99 anyway) deities will probably be spending more time
2635 * Added server support for building under NT, including mods from
2636 Doug Hay and Steve McClure to get the server building and running
2637 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
2639 * Added Doug Hay's ntthread.c implementation for NT threading.
2640 * Added max pop column to "show sector stats" output.
2641 * Added lboard command for boarding land units from sectors. Only raw
2642 mil can board land units, and only mil and land units aboard the unit
2643 being boarded fight back.
2644 * Added GODNEWS option. When enabled, the deity giving people stuff
2645 is shown in the news.
2646 * Added bridge tower sector ('@')
2647 * Added BRIDGETOWERS option. When enabled you can build bridge towers
2648 from a bridge span. You can then build bridge spans from the tower.
2649 If the tower is destroyed ( <20% eff) bridges connected fall unless
2650 supported on the other side. You can only build bridge towers in open
2651 water not adjacent to land and other towers. Expensive.
2652 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
2653 it is deity creatable only (can't redesignate unless you wasteland it
2655 * Changed "info all" to no longer use printdir, instead it just uses the "all"
2656 info page which contains this information.
2657 * Changed so you can now load up to 2 spy units onto non-land unit carrying
2658 submarines if the LANDSPIES option is enabled. Useful for sneaking up
2659 to shore and spying on your neighbors.
2660 * Changed so spies unloaded from ships are not given as gifts, they are just
2662 * Changed build command to handle building towers ("build t")
2663 * Changed show command to show tower stats ("show t b")
2664 * Changed reject so you can now reject things from any country except
2665 deity countries (this now includes sanctuary countries and visitor
2666 countries you don't want to deal with)
2667 * Changed ndump to dump nuclear stockpile ID as well.
2668 * Changed flash so that if someone allied to you is either not logged on or
2669 not accepting flashes, you are notified. This is info you could gain
2670 otherwise since you can see other countries that are allied to you via
2672 * Fixed bug in news command when HIDDEN mods are enabled.
2673 * Fixed distribute command to only write out to the database if we
2674 actually changed the sector (i.e. if we really moved the dist
2675 center, we write. Otherwise, it makes no point.)
2676 * Fixed threshold command to only write out to the database if
2677 we actually changed the sector (i.e. if we really changed the
2678 threshold, we write. Otherwise, it makes no point.)
2679 * Fixed - population growth and truncation in "Update-sequence.t" info
2681 * Fixed the way fortify takes mobility away from a land unit if
2682 engineers are present.
2683 * Fixed bug in buying commodities at the last minute not resetting the
2684 time correctly in all situations.
2685 * Fixed bug in building nukes where it would always ask if you tried
2686 building more than one at a time.
2687 * Fixed bug where if you put (either by building or by transporting)
2688 more than 127 of one type of nuke in a sector, they all got lost. A
2689 negative wrapover sort of thing.
2690 * Fixed ndump to print # of stockpiles dumped.
2691 * Fixed ndump.t to reflect changes
2692 * Fixed bug in build command that didn't account for EOL characters.
2693 * Fixed bug where you could use planes to drop conquered populace
2694 * Fixed bug in distribute command in how it checked for current distribution
2696 * Fixed pr_flash and pr_inform to no longer send messages if the player
2697 is still in the process of logging in (i.e. not in the PLAYING state)
2698 * Fixed report command output for deities.
2699 * Fixed bug in nuclear damage either taking out submarines when it
2700 shouldn't, or not taking them out when it should.
2701 * Fixed bug in loading units that are carrying units onto other units
2702 (note that it doesn't happen since only HEAVY units can carry other
2703 units and that check works, but that might change some day, and we
2704 don't want units carrying units to be carried by other units, etc. :) )
2705 * Fixed info pages to reflect new sector types.
2706 * Fixed info pages to reflect new spy unit capabilities.
2707 * Fixed show commands to only show trade ships if the TRADESHIPS option
2709 * Fixed build command to only allow building of trade ships if the
2710 TRADESHIPS options is enabled.
2711 * Fixed up some definitions located in many places used for checking
2712 sectors for navigation rights.
2713 * Fixed power.t to correctly describe NEW_POWER formula.
2714 * Made HIDDEN option run time configurable.
2715 * Made LOSE_CONTACT option run time configurable.
2716 * Made ORBIT option run time configurable.
2717 * Made SAIL option run time configurable.
2718 * Made MOB_ACCESS option run time configurable.
2719 * Made FALLOUT option run time configurable.
2720 * Made SLOW_WAR option run time configurable.
2721 * Made SNEAK_ATTACK option run time configurable.
2722 * Made WORLD_X and WORLD_Y run time configurable.
2723 * Made MARKET option run time configurable.
2724 * Made LOANS option run time configurable.
2725 * Made BIG_CITY option run time configurable.
2726 * Made TRADESHIPS option run time configurable.
2727 * Made SHIPNAMES option run time configurable.
2728 * Made DEMANDUPDATE option run time configurable.
2729 * Made UPDATESCHED option run time configurable.
2730 * Made LANDSPIES option run time configurable.
2731 * Made NONUKES option run time configurable.
2732 * Made PLANENAMES option run time configurable.
2733 * Removed SMALL_SERVER stuff (unused baggage)
2734 * Removed trading post sector ('v')
2736 Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
2737 * Fixed bug in aircombat where planes in flight could intercept air
2738 defense planes and take no damage (i.e. they got to fight twice,
2740 * Fixed bug in freeing memory after performing missions that could crash
2741 the server (it mainly happened after an interdiction mission using
2742 planes and escorts, where some escorts came from airports that didn't have
2743 bombers going up. Freeing the leftover escorts was crashing the server.)
2744 * Fixed bug where you could load non-existant units if you were allied
2746 * Fixed bug where you could pin-bomb a plane with itself.
2747 * Fixed bug where satellites over a bridge may get killed if the bridge
2749 * Fixed bug where land units on a ship in the same sector as a bridge
2750 that is splashed may get sunk.
2751 * Fixed bug where planes on a ship in the same sector as a bridge
2752 that is splashed may get sunk.
2753 * Fixed doconfig with correct empire site text.
2754 * Fixed major problem with abms not firing, and sometimes crashing
2756 * Fixed bug in land units counting up loaded units wrong.
2757 * Fixed doconfig makefile to have doconfig.c as a dependency.
2758 * Fixed bug in resetting commodities (the comm_uid was not being
2760 * Fixed bug in repaying loans not working correctly (the l_uid was not
2761 being properly set.)
2762 * Fixed bug in buying items from the trading block not allowing you
2763 to due to a perceived change in item status.
2764 * Fixed bug in mfir.c where a bogus input to a target could crash
2766 * Fixed bug that after you read telegrams new telegrams may not send
2767 an inform message (the old telegram flags were not cleared.)
2768 * Fixed bug where fort support distance calculations are calculated
2769 twice instead of just once. This bug caused a lower percentage
2770 of support fire than designed.
2771 * Fixed bomb.t to reflect land unit changes.
2772 * Put in some integrity checking for planes returing from bombing runs.
2773 * Added ability to edit land unit that a land unit is loaded on in
2775 * Consolidated bridgefall code into "knockdown" function (this code
2776 existed in at least 3 places, and was different in all of them.)
2777 * Subs returning fire are no longer reported in the news.
2778 * Visitor countries can now use the 'motd' command.
2779 * When trying to use a visitor country, if it is in use, you are not told
2780 by whom, just that it is in use.
2781 * Optimized (slightly) support fire from forts not getting supply and
2782 shells if not needed (out of range)
2783 * Updated Education.t
2784 * Modified (increased) chances of hitting mines slightly.
2785 * Removed unused variables from shp_check_mines.
2787 Changes to Empire 4.0.17 - Fri Jul 31 06:12:21 PDT 1998
2788 * Added ability in edit to change coastal flag for sectors.
2789 * Added ability in edit to edit plague values for ships.
2790 * Added ability for "spy" to report all units/planes not owned by you
2791 that exist in the sector you are spying from.
2792 * Modified naval planes and anti-sub planes.
2793 * Changed so that missiles and bombs that miss their targets cause
2794 collateral damage in the target sector (they have to land somewhere!)
2795 * Changed llook so that non-spy units are required to have at least 1
2796 military personnel on board to see anything.
2797 * Fixed "llookout.t" to reflect change for military requirement.
2800 * Added "lmine" flag for deities to see what sectors have mines in them
2801 (works for sea and land mines, used "lmine" to distinguish it from "min"
2802 which determines mineral (iron) content of a sector.)
2803 * No longer able to pin bomb land units on a ship.
2804 * Land units are required to have at least one military loaded to perform
2806 * Firing land units are required to have at least on military loaded to
2807 be able to fire (or return fire.)
2808 * Spies are not always seen when being pinbombed. You have to look very
2809 carefully for them (as you usually would.)
2810 * Fixed typo in "Spies.t"
2811 * Added new info about spy ability to spy.t.
2812 * Updated tax information in Innards.t and Update-sequence.t
2813 * Fixed typo in fire.t information about units firing on ships.
2814 * Loading military onto land units now resets fortification. (You gotta
2815 re-fortify the new guys.)
2816 * Fixed bug where planes that were mine capable could not drop mines if
2817 they were not cargo capable.
2818 * Fixed bug in potentially crashing in update code for nations tech/research.
2819 * Fixed bug in execute putting you into execute mode incorrectly.
2820 * Fixed bug in board not allowing land units to board from 0 mobility
2822 * Fixed bug where interdicted land units that were missed displayed
2823 a "SPLASH! Bombs miss your ships" message.
2824 * Fixed bug in minesweeping sectors where, even with mobility or
2825 having the sweep ability, ships would get hit by mines for doing
2827 * Fixed bug in count_land_planes always writing out land units unnecessarily.
2828 * Fixed bug in count_planes always writing out ships unnecessarily.
2829 * Fixed bug in lnd_count_units always writing out land units unnecessarily.
2830 * Fixed bug in count_units always writing out ships unnecessarily.
2831 * Fixed bug in llook that reported units on ships.
2832 * Fixed bug in llook that reported satellites launched over the unit.
2833 * Fixed bug in llook that always reported spies (it should be a 10-100%
2835 * Fixed bug in anti possibly not saving lost items correctly.
2836 * Fixed bug in planes getting extended range when on missions and the
2837 op center is not where the plane is located.
2838 * Fixed bug in land unit defensive strength not being based on the eff of
2839 the unit when calculating odds of a battle.
2840 * Fixed bug in board not reporting consistant information.
2841 * Fixed bug in the way land unit casualties were being taken.
2842 * Fixed bug where land units on ships could return fire.
2843 * Fixed bug where land units on other land units could return fire.
2844 * Fixed bug where land units on other land units could fire.
2845 * Fixed bug in attacks/assaults/boardings spreading plague incorrectly.
2846 * Fixed bug in updating plague for ships.
2847 * Fixed bug in updating plague for land units.
2848 * Fixed bug in updating plague for attacking/defending land units.
2849 * Fixed bug where you couldn't pin-bomb land units that were < 20% eff.
2850 * Fixed bug which revealed the owner of torping subs when on a mission.
2852 Changes to Empire 4.0.16 - Fri Jun 12 08:52:06 EDT 1998
2853 * Added patches sent in by Steve McClure, Sverker Wiberg and Curtis
2854 Larsen. They are described with other changes below.
2855 * Fixed bugs in the following commands that allowed two cooperating
2856 countries to create infinite numbers of any commodity and/or cash
2857 at any time (race conditions in the server): build, board, deliver,
2858 designate, distribute, explore, fuel, improve, load, ltend, mobquota,
2859 move, name, order, reset, sail, sell, set, tend, territory, test,
2860 threshold, torpedo, transport, unload
2861 * Fixed bug in board command giving out too much information about a
2862 non-owned sector when it shouldn't be.
2863 * Fixed bug in board command when firing on a sector in defense before
2865 * Fixed bug in rangeedit allowing plane(s) to possibly be stored wrong.
2866 * Fixed bug in launch allowing plane to possibly be stored wrong after
2868 * Fixed bug in lrangeedit allowing land unit(s) to possibly be stored wrong.
2869 * Fixed bug in morale allowing land unit(s) to possibly be stored wrong.
2870 * Fixed bug in arm/disarm allowing a plane to possibly be stored wrong.
2871 * Fixed bug in loan sometimes not writing database correctly.
2872 * Fixed bug in collect.

2966 * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box.
2967 * Took out autosupply of airports when bombing or dropping shells.
2968 (This was the only commodity this was done for, and it was creating
2969 problems since supply is still somewhat broken somewhere)
2970 * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
2971 submitted patches, which collectively included cleaning up most
2972 of the server prototypes and bogus declarations. Many thanks.

2998 * Fixed bug in parse.c that was screwing up double quotes in conditional
3000 * Military in a sector now only produce up to maxpop, just like civvies
3001 and uw's. No more stuffing 6K mil into a mountain to max it out. You
3002 can still hold more mil there over the updates, but the extras just
3003 won't produce anymore.
3004 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
3006 * Fixed bug in day of week calculation for server up time in common/keyword.c
3007 that is used for gamedays.

3073 * Fixed "sell.t" info page.
3074 * Fixed bug in "buy" where not entering the price correctly could cause
3076 * Fixed "sell" so that at least 1 mobility is required to sell goods. Keeps
3077 the midnight "raid and sell" abuse down. :)
3078 * Fixed "show plane cap" to move the last column over 1 more where it should
3080 * Fixed timestamps to be updated for units/planes on ships/units that move,
3081 since those units/planes move too.
3083 Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
3084 * Fixed bug in nstr_exec that was wiping out the previous conditional.

3089 Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997

3091 numbers were screwing things up good...
3092 * Fort sector's coordinates are no longer printed when auto-firing at
3094 * Subs can now surface and fire deck guns (again) They can also be
3095 hit by return fire when doing so.

3111 * Fixed land unit names to be more consistent.
3112 * Fixed mission.t info page.
3113 * Fixed bug in that if mission_mob_cost was set to 0, even negative
3114 mob units should be able to be put on missions.
3115 * Removed restriction on things needing to be at least 60% to be put
3116 on a mission. Note that while you can put them on missions at < 60%
3117 now, when trying to do the mission, it still checks the eff. This
3118 is to help in automatic setup (build, put on mission, forget) instead
3119 of having to come back repeatedly.
3120 * Spies caught in Neutral or Friendly countries cause the Neutral or
3121 Friendly country to go Hostile towards the owner of the spy.
3122 * Tweaked ammunition numbers for artillery units.
3123 * No more automatic declarations of War should be made. You will go
3124 hostile, but since going to war doesn't increase your countries
3125 defenses, and is purely political, it is left to the player to go

3128 * Fixed bug in "lmine" that was crashing the server if the land unit was
3130 * Fixed buy so that if you specify a product, you can only bid on that

3137 client for comparisons.
3138 * Changed last minute market/trade timers to increment 5 minutes. 2 minutes
3140 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
3141 * Commented out the logging of the market checking in server/marketup.c,
3142 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
3143 pretty much useless data that made parsing the server.log file more
3144 more difficult than it needed to be.
3145 * Fixed crashing bug in ldump.
3146 * sdump, ldump, ndump, pdump and dump now print out the current
3147 timestamp on the "DUMP XXX" line.
3148 * Fixed denial of service bug in lib/player/accept.c in
3149 player_find_other function.
3150 * Fixed bug in shark reporting incorrect buyer of the loan.
3151 * Fixed bug in sdump.c (case 0 should have been case 10)
3152 * ldump and sdump now always print the fuel column if asked for,
3153 even if opt_FUEL is turned off. In the case that it is turned
3154 off, the fuel is listed as 0.
3155 * Added "timestamp" field, which is updated every time an item is
3157 * Fixed up the Clients.t info page.
3158 * sdump now prints trade ship building origin.
3159 * sdump now always prints name even if SHIPNAMES isn't defined. If
3160 it is not defined, then the name is empty.
3161 * Added "timestamp" to info/Concepts/Selector.t
3162 * Added some more relevant info to info/Server/Empire4.t
3163 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
3164 is no longer torn down when a sector is re-designated.
3165 * Fixed sell.t to more accurately reflect the time-delay market.
3166 * Fixed read.t and wire.t to reference accept and reject.
3167 * Fixed reject.t not referencing accept command.
3168 * Fixed collect.t to more accurately reflect what goes on when collecting
3170 * Fixed financial.t to reflect defaulted loans.
3171 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
3173 * Fixed "census.t" (had incorrect reference to "info syntax" instead
3176 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
3177 * Increased damage from depthcharges because on increased damage from
3178 torpedos. Sub frange decreased to be more balanced with destroyer frange.
3179 * Intelligence reports (spy) on units will now report the estimated number

3182 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
3183 land units, planes, and nukes.
3184 * If fields are provided, dump will only supply those fields requested.

3201 * Fixed anti to write back target country so che will continue to fight
3203 * Fixed llookout to show correct estimate on number of mil on unit.
3204 * Added buildable architecture "hp". This type will build the server on
3205 a HP/UX machine using the standard compiler instead of gcc.
3207 Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
3208 * Fixed bug in update/distribute.c where pathcost was not being called with
3209 the MOB_ROAD argument (and thus distribution costs could be GREATLY
3210 affected.) - Thanks Ice!
3212 Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996
3213 * Fixed Solaris port using gcc.

3254 else for that matter.)
3255 * Fixed llook in commands/look.c
3256 * Fixed che bug in subs/nstr.c
3257 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts

3261 * Fixed count_bodies in attsub.c

3266 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
3267 infrastructure. When off, the defensive infrastructure is the same
3268 as the sector efficiency, and you can't improve it. This is OFF by
3272 * Land units are now built with a default reaction radius of 0.
3273 * Changed name of lt artilleries to "lat" from "lart" so you can now build
3275 * Lowered the speed and firing range of pt boats.
3276 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
3278 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
3279 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
3280 1.5 * ETU_RATE for ships.)
3281 * Conquered civvies only pay 1/4 taxes.
3282 * Railways don't get torn down when you rebuild sectors anymore (but roads
3283 and defenses do (if enabled.)
3285 Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
3286 * Added "extern double tradetax" to check_trade in trad.c
3287 * Improved description of data directory in build.conf
3288 * Fixed bug in attacking land units that retreat so they now get
3289 charged mobility for attacking.
3290 * Fixed dump to report road, rail and defense of a sector at the end.
3291 * Fixed doconfig bug in not checking the right directory to see if the
3292 "data" directory existed or not before trying to create it.
3293 * "change" now works for sanctuary countries.

3298 * Supply units were slowed down to the speed of infantry units.
3299 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
3300 * Bars interest is up to $250 per 1K again.
3301 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
3302 * Fixed various info pages.
3303 * Fixed bug in people not getting truncated when broke (this was thought
3304 to be fixed, but wasn't. Now it is, dammit!)
3305 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
3306 * Market/trade taxes and trade ship payoff figures were added to version.

3315 Changes to Empire 4.0.0 - Wed Aug 21 1996
3316 * Initial Wolfpack release - Long live the Wolfpack!!!!
3317 * Cleaned up the build environment. Now all that is needed is to edit the
3318 build.conf file, answer the questions there and type "make <arch>" to
3319 build for a specific architecture. Thus, no more reliance on gnumake
3320 or special shell scripts.
3321 * We are now shipping the pre-built info pages with the server for those who
3322 Don't want to build them. You can also still just type "make" and have
3323 the info pages build, but it doesn't completely work (i.e. rebuild new
3324 Subjects) if you don't have perl5 installed.
3325 * Put in the "help" command that does the same thing as "info".
3326 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
3327 wish to support it. 2) We envision a better scheme for doing similar
3328 things will come along.
3329 * Put in MOB_ACCESS - This allows real-time updating of mobility.
3330 * Put in MARKET - This is the time-based market (yes, still teleports,
3331 but it's not as bad as it was.)
3332 * Lots of the documenation has been updated, but there is more to do.
3333 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
3334 enabled, you don't need any of that type of material to build things.
3335 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
3336 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
3337 any materials to build a bridge.
3338 * There is no mobility cost for assigning missions. But, there is also
3339 no longer any benefit for being on a mission either.
3340 * Damage is the same for all commodities (people too.) This means you
3341 can deity shell/bomb sectors again.
3342 * Units are now dependant on tech. What this means is that their statistics
3343 now increase with tech. In addition, there is only 1 type of each basic
3344 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
3345 This reflects the idea that as you learn more, you learn how to not only
3346 build better units, but you learn to build units better. :) This also
3347 opens the door for a "lupgrade" command along the same lines as the
3348 "upgrade" command for ships.
3349 * Units now have a minimum mob cost for attacking a sector. Marching
3350 mob costs have not changed.
3351 * Starting units have been removed. This means that at the beginning, people
3352 may live a little longer since their neighbor can't come visiting quite
3354 * Shells are no longer required to build units.
3355 * Mil are no longer required to build units.
3356 * Mil are no longer an intrinsic part of a unit. They are now a loadable
3357 commodity. The way a unit's defense/att bonuses work now are
3358 attack = (att * mil * eff)
3359 defense = (def * mil * eff)
3360 In addition, when a unit takes damage, both the eff and the mil go
3361 down. You can quickly toss in new hacks, but you need to wait to repair
3362 the unit at the update. Thus, you can now look at unit's efficiency
3364 * You need at least 1 mil on a unit to march it (spies are the exception.)
3365 * Units always react if in range and they have the mobility, no matter
3366 what their efficency.
3367 * Units may now march anywhere - in your own sectors, deity owned sectors
3368 or allied sectors, with 1 exception, spies. Also, your units can get
3369 trapped if your ally declares non-alliance with you while your units
3370 are still in his country.)
3371 * Units always march at their speed, efficiency doesn't matter.
3372 * LANDSPIES was added - This creates land unit based spies. Spies may march
3373 anywhere, with a chance of getting caught (except in allied territory.)
3374 See "info Spies" for more info on them.
3375 * Planes may now be based out of allied airports. Landing planes on
3376 ships/sectors you do not own no longer changes thier owner. You can only
3377 land on owned/allied sectors/ships, and you may only
3378 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
3379 you are allied with goes hostile at you, your planes are now stuck there.
3380 Note that if you are using an allied airport, their commodities get
3381 sucked up, not yours (obviously.)
3382 * Planes are now tech-based. Their statistics increase as their tech
3383 increases. Deleted extraneous planes.
3384 * There is a new toggle, "techlists", which allows you to see what you
3385 can build/stats/capabilities sorted by tech instead of groupings.
3386 * Ships are now tech-based. Their statistics increase as their tech
3387 increases. Deleted extraneous ships.
3388 * Che can now be lessened by making happiness. If you have more happiness
3389 than your conquered populace, they don't fight as hard or recruit as
3390 much. If you have less than them, they fight harder and recruit more.
3391 It's not much though - it ranges from 2.0 in your favor to only 0.8
3392 against you (whereas it was always 1.0 before.) So, it definitely
3393 favors the attackers to make lots of happy now.
3394 * Bridgeheads can only be built on coasts.
3395 * Players command was fixed so you only see allies, and don't get
3396 approx #'s of players anymore.
3397 * POSIX threads support has been added.
3398 * The attack bmap bug has been fixed.
3399 * BTUs regenerate 3 times faster now.
3400 * GRAB_THINGS is off by default.
3401 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
3402 as a default (you couldn't make wasteland before with FALLOUT, now
3404 * You can now deliver military and civilians.
3405 * Added SHIP_DECAY option - off by default (turns off ships decaying out
3406 at sea if not enough mil.)
3407 * The reverting owner bug has been fixed in territory, thresh, dist
3408 and deliver. There are probably more, and when found, will be fixed.
3409 * The "sectors don't starve when stopped or broke" bug has been fixed.
3410 * The "people never get truncated" bug has been fixed.
3411 * Added infrastructure to sectors. What this means is that a sector
3412 can now have it's mobility improved by building both roads and
3413 railways. It also means that a sectors defense is now based on the
3414 defensive infrastructure you build into the sector (no more intrinsic
3415 better defenses based on the sector, you determine which sectors are
3416 defended heavily, and which aren't.)
3417 * The defensive value of a sector no longer relies on the efficiency of
3418 the sector. Instead, it relies on the defensive efficiency of the sector.
3419 Thus, the "production" and "defensive" aspects of sectors have been
3421 * "show sect stats" now shows the maximum defensive value for sectors.
3422 * Changed sector structure to take floats for off/def values so we can use
3423 a base of 1 instead of 2.
3424 * Added "improve" and "sinfrastructure" to support the infrastructure
3426 * Added L_TRAIN units which can only travel along railways. Very fast on
3427 efficient railways, slow on non-efficient ones.
3428 * Added the ability for units to carry other units.
3429 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
3430 * Forts only cost $500 to build and 100 hcms now (since they don't get any
3431 better defenses automagically.)
3432 * Modified "show sect build" to show the costs for building up the
3433 infrastructure of a sector.
3434 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
3435 spyplanes too) to show the new infrastructure stuff, rounded of course.
3436 * Added Drake's info->html scripts, with some modifications, so you can
3437 now type "make html" and have your info pages built as html files too.
3438 This adds a new directory, "info.html", to the build tree.
3439 * Modified upgrade so that planes and land units may now be upgraded.
3440 * Added pstat command to list the statistics of your planes.
3441 * Added lstat command to list the statistics of your land units.
3442 * Added sstat command to list the statistics of your ships.
3443 * Added nmap command to show a map of your sectors after their new
3444 designations have taken place.
