1 Changes to Empire 4.3.10 - Fri Aug 24 17:26:56 UTC 2007
2 * The custom table reader detects more errors.
3 * Do not leak world creation time in files and fairland, because
4 that facilitates attacks against the PRNG. This misfeature crept
6 * Remove the ancient, crufty non-UCONTEXT system-dependent LWP code.
7 Using it required manual hackery since 4.3.0, and it hasn't been
9 * Plug file descriptor leak in add command.
10 * Don't kill player connections violently when their thread appears
11 to be hung. Threads being aborted by update or shutdown could be
12 misidentified as hung, and the violence could lead to resource
13 leaks, locked out updates, and corrupted game state.
14 * Fix LWP to wake up threads sleeping for a time reliably. Before,
15 players with a sufficiently fast connection could starve out
16 threads system threads, including the update.
17 * Fix a class of bugs that made commands behave differently while the
18 update is attempting to take control:
19 - No MOB_ACCESS mobility was gained.
20 - Telegrams were miscounted.
21 - Bulletins got misfiled as production reports.
22 - The navigate command ignored sail paths.
23 - The declare command was more quiet, and declarations of war
24 failed silently when SLOW_WAR was enabled.
25 - Many messages got misdirected to bulletins.
26 Some of these bugs go back all the way to Empire 2, ca 1995.
27 * New deity command reload, effect similar to SIGHUP.
28 * Not voting for a demand update no longer lets you veto further
29 demand updates. This feature was flawed (it encourages players to
30 vote late so that they can tactically vote no and thus build up
31 veto rights), virtually unused, and buggy.
32 * Fix zdone not to claim to have triggered an update when they're
34 * New update scheduler and ETU clock:
35 - New schedule file. See doc/schedule for how to use it. Replaces
36 econfig keys update_policy, adj_update, update_times, hourslop,
37 blitz_time. A change of schedule does not require a server
39 - The force command can no longer force updates in the future.
40 Edit the schedule file for that.
41 - New command show updates to show the update schedule. Obsoletes
43 - New xdump game and xdump updates.
44 - New utility program empsched to help test update schedules.
45 - Replace option DEMANDUPDATE and econfig key update_demandpolicy
46 by econfig key update_demand.
47 - econfig key update_demandtimes no longer applies to scheduled
49 - You now receive new BTUs at the update in addition to login.
50 - You now always gain the same BTUs and MOB_ACCESS mobility per
51 turn, even when the update schedule changes, updates get missed,
52 or unscheduled demand updates run.
53 - Remove the mobupdate command, because porting it to the new ETU
54 clock is not worth it.
55 * Redesign of synchronization between commands, update and shutdown,
56 and how updates are triggered:
57 - Simplify update to a single thread waiting for the trigger.
58 Before, three update threads had to perform a carefully
59 choreographed dance to make updates happen. The dance relied on
60 thread priorities for correctness, but they're only implemented
61 by LWP. With pthreads and under windows, demand updates were
62 prone to two update threads starting up concurrently. Even with
63 LWP, forced and demand updates could lead to double updates.
64 - Use a lock for synchronization: commands take it shared, update
65 and shutdown take it exclusive. This makes update and shutdown
66 block until all aborted commands terminated and gave up their
67 lock. Before, they proceeded blindly after waiting two or one
68 seconds respectively, which was cheesy and unsafe.
69 - New commands no longer fail while the update is pending, they are
70 delayed until after the update.
71 - New commands can no longer start during shutdown. Before, they
72 could, but risked getting killed violently, corrupting the game
74 - Fix command execution so that commands blocked in writing
75 redirections are abortable. The bug allowed players to delay
76 update and shutdown indefinitely.
77 - Fix shutdown not to let player threads block on output. This
78 let players delay shutdown indefinitely.
79 - Fix reading of player input not to block again after update or
80 shutdown aborted it. The bug allowed players to delay update and
81 shutdown indefinitely.
82 * Thread priorities are only implemented by LWP and no longer used.
83 With LWP, they let players with a sufficiently fast connection
84 starve out the threads that clean the lost file and kill idle
85 connections. Drop them.
86 * Show nuke rounded required research incorrectly.
87 * Log unprintable characters as octal escapes rather than question
88 marks in the journal file.
89 * The files program no longer changes permissions of existing files.
90 * The files program now creates all files with permissions ug=rw and
91 all directories ug=rwx, modified by umask.
92 * Fix a bug that could make arm, disarm and nuke detonation work with
93 a used-up nuke instead of the armed one. This could be abused to
94 detonate nukes multiple times. Broken in 4.3.3.
95 * Fix nuke detonation output for zero blast radius.
96 * Plug memory leaks in thread code.
97 * Fix a bug that made LWP I/O wakeup unreliable.
98 * New march sub-command v for view.
99 * Journal was initialized before threads were, which was wrong.
100 * Fix server not to create a journal on SIGHUP when it is disabled.
101 * shutdown 0 now requests immediate shutdown instead of cancellation
102 of a pending shutdown. shutdown -1 now cancels.
103 * flash and wall no longer split long message lines.
104 * Fix a bug in collect that screwed up a fully collected loan instead
105 of deleting it. The screwed up loan could not be sharked or
106 collected, but it could be repaid.
107 * Remove the wait command, it's been broken and restricted to deity
108 since Empire 2, ca. 1995.
109 * Budget failed to take sector production into account for predicting
110 unit repairs. Before 4.3.6, this bug bit only when you fooled
111 around with budget priorities.
112 * When unit repairs is limited by materials, the efficiency gain is
114 * Ship repairs outside harbors and plane repairs by carriers used to
115 consume commodities when and as far as available. Now, they
116 consume the same fraction of the real cost of each commodity,
117 i.e. commodity use is limited by the most scarce commodity.
118 Neither old nor new behavior make much sense, but the new code is
120 * Code refactoring and cleanup, in particular to make the Windows
123 * Info file and manual page updates. All manual pages are now
124 installed in section 6.
126 Changes to Empire 4.3.9 - Sat Jan 6 12:42:19 UTC 2007
127 * Fix declare to prevent the deity from changing relations for a
128 player to self. Allow the deity to set the relations of a player
130 * Fix arm not to put the same nuke on multiple planes (broken in
132 * New option AUTO_POWER.
133 * Sectors now repair allied land units.
134 * Sectors now repair only own and allied planes.
135 * Fix repair of planes on foreign carriers: repair allied planes,
136 ignore the others. Before 4.3.3, carriers destroyed rather than
137 repaired foreign planes. Since 4.3.3, foreign planes were treated
138 as recoverable error.
139 * Fix automatic fortification of land units to use all excess
140 mobility even when mobility delta exceeds mobility maximum.
141 * Disable automatic fortification of land units when MOB_ACCESS is
142 on, because it is prohibitively slow then (broken in 4.2.13).
143 * Budget now shows level production (tech, education, research and
144 happiness) rounded instead of randomly rounded.
145 * Fix update not to randomly flush small level production to zero.
146 * Fix overly restrictive game file locking under Windows (broken in
148 * Fix navigate to charge mobility for sweeping mines without moving
152 Changes to Empire 4.3.8 - Fri Oct 20 18:30:28 UTC 2006
153 * Ships no longer produce stuff when the government is broke.
154 * Fix land unit casualties in revolts.
155 * Fix security units not to raid friendly che.
156 * Fix update sequence to ensure stopped sectors don't work on the
157 ships, planes and land units in the sector. Before 4.3.6, this bug
158 bit only when you fooled around with budget priorities.
159 * Fix canal loading (was broken in 4.3.0).
160 * Fix tend not to tend land units that could not be loaded.
161 * Make xdump command available before break, but deny access to game
163 * Lock game files to prevent concurrent access by multiple programs.
164 fairland does not yet obey the lock.
165 * Fix production to consider sector item limit.
166 * Fix swapsector to update coastal flag correctly (broken in 4.3.0).
167 * Enhanced mapping sub-commands in move, test, explore and transport.
171 Changes to Empire 4.3.7 - Fri Jul 14 23:05:19 UTC 2006
172 * Sanctuaries are again fully populated with civilians (4.3.6 changed
173 the limit, but not the population). Food is now spread evenly
175 * Fix path finder to find shortest naval and aerial paths again
177 * transport's map sub-command now does the right thing for a unit
179 * Fix bug in map sub-command of move, explore and transport that
180 passed junk to map command. Could theoretically crash.
181 * Food need reported by starvation was one short for sectors without
183 * Change land unit ammunition use back to what it was before 4.2.3.
184 This lets deities customize ammunition use independent of damage.
185 It also substantially reduces ammunition consumption at high tech.
186 * navigation and march enhancements:
187 - Sub-command 'f' now takes an optional ship / land unit number.
188 - Mapping sub-commands now take an optional ship / land unit
190 - New sub-command 'd' to drop mines.
191 * Let minesweepers retreat at their full speed (missed in 4.3.6).
192 * SUPER_BARS cannot be harmed, so don't interdict them.
193 * Don't let trains and non-trains march together for now, because the
194 march code isn't prepared for that.
195 * New mapping flag 'n' to show nukes.
196 * Mapping flag '*' now shows nukes as well.
197 * New command nbmap to bmap around a nuke. Overload command nmap to
198 map around a nuke when given a nuke argument.
199 * Fix an inconsistency that gave tactical bombers a small bonus
200 vs. flak when pin-bombing.
201 * Fix production to show the designation that actually produces, not
202 the designation as it is now (broken in 4.3.6).
203 * Fix accidental whitespace change in output of sdump, pdump and
204 ldump that crept into 4.3.5.
205 * Support user-defined sector types and products in custom tables,
206 not just customization of existing ones.
207 * Fix off-by-one bug in budget that used to be masked by budget
208 priorities until their demise in 4.3.6. The bug could crash the
209 game on certain systems.
213 Changes to Empire 4.3.6 - Tue Jun 20 18:46:18 UTC 2006
214 * The shutdown command now terminates the server process correctly
215 even with LinuxThreads pthreads under Linux 2.4 and earlier.
216 * Cope with old versions of groff (broken in 4.3.0).
217 * You can now arm allied planes with nukes.
218 * Taking a nuke off a plane gives it to the sector owner again.
219 Feature was accidentally dropped in 4.3.3. Recipient must be
221 * Naval path went bananas for impassable end sectors (broken in
223 * New econfig key disabled_commands.
224 * New territory selector dterr, restricted to deities. The territory
225 command defaults to it for deities.
226 * Let land units attack as long as they have positive mobility,
227 except for high-mobility terrain (mountains), where the rules
228 remain as they were: land units need to have all the mobility
229 charged for the attack, not counting combat and moving in to
230 occupy. Rationale: Making sure your land units reach attack
231 positions with enough mobility left is a pain in the neck.
232 Requiring only positive mobility is friendlier, but allowed rushing
233 of mountains, so we make an exception there.
234 * Can typeset info pages as PostScript. Result isn't exactly pretty.
235 * Support disabling of infrastructure in infra custom table. Remove
236 redundant option DEFENSE_INFRA. show command now shows only enabled
238 * Fix crash on empty argument in bmap, lbmap, lmap, map, nmap, pbmap,
239 pmap sbmap, smap (broken in 4.3.1).
240 * New, simpler sector mobility cost formula:
241 - The basic cost is still a linear function of sector efficiency,
242 with customizable cost at 0% and at 100%. The latter used to be
243 derived from the former. The show command shows both parameters
245 - Mountains are no longer a special case.
246 - Tweak costs: mountains now range from 2.4 to 1.2 instead of 2.174
247 to 1.304, highway, bridge head, bridge span and bridge tower
248 range from 0.4 to 0.001 instead of 0.2 to 0.001, and wilderness
249 is 0.4 flat instead of 0.6 to 0.4. All sector types mortal
250 players can designate now cost the same at 0%. That's a feature.
251 - Road infrastructure now reduces cost up to 90%, linear in road
252 efficiency (used to be close to that, but non-linear). Same for
253 rail infrastructure, but 99%. Adapted from Ice World V.
254 - Double land unit minimum cost to 0.02, to slow them down on
256 - Change land unit cost penalty in newly taken land to an extra 0.2
257 instead of a minimum of 0.2, to reduce penetration depth.
258 * Reduce bridge head defense and collect value to match highway's.
259 * sinfrastructure displayed bogus rail mobility costs when there was
261 * Retreating engineers took full landmine damage instead of half.
262 * Fix socket creation code not to print a null pointer.
263 * Fix login option code not to search beyond end of table (broken in
265 * Spy planes and satellites can no longer spot landspies.
266 * Spy planes can now spot surface ships at sea. They can no longer
267 spot land units loaded on ships or land units.
268 * Fix train retreat mobility cost, and don't permit retreat off rail.
269 * Change maximum population to 100 for plains (was 49), mountains
270 (was 99), bridge spans and bridge towers (was 999), and to 1000 for
271 the other habitable sector types (was 999).
272 * Let minesweepers navigate at the speed their stats indicate by
273 letting them sweep on the move at no extra mobility charge.
274 * Reduce chance for planes to abort from 100-eff (if eff<80) to
275 80-eff. This should make it easier to punch through air defense,
276 flak in particular, and increase the risk of getting shot down.
277 * Ship and land unit flak intensity is now proportional to efficiency.
278 * Ship and land unit flak intensity is no longer scaled by the tech
279 of the owner of the last thing firing. It's still scaled by each
281 * All ships and land units firing flak now spot the plane and are
282 spotted by the plane. Previously, spotting stopped as soon as flak
284 * Inefficient land units were overcharged mobility when reacting.
285 Broken when Empire3 changed land unit mobility use not to depend on
286 efficiency, except for supply units.
287 * New journal file to log complete player input plus selected
288 important events. Controlled by new econfig key keep_journal, off
290 * Fix unsafe shutdown on SIGINT and SIGTERM.
291 * Fix land unit path finding: paths weren't always cheapest (broken
292 in 4.0.2), and trains could be sent down paths without rail (never
293 worked). Also fixes unit reaction path cost.
294 * The custom table reader can now deal with sector, item, product and
295 infra tables more comfortably.
296 * Remove option BIG_CITY. Deities can customize the sect table to
298 * Many more selectors can now be compared with names, not just
299 numbers. This includes nations, e.g. census ?old=Mirkwood. Does
300 not fully work for queer names like &&&.
301 * Let land units on missions support, just like ships.
302 * Don't let units loaded on a train react.
303 * Change update sequence to repair ships, planes and land units after
304 sectors produce. This makes repairs use new avail instead of old.
305 * Let players stop and start units.
306 * Remove budget priorities.
307 * Make plane report easier to understand.
308 * Change land report to show carriers in the same format as plane and
311 * Info file and manual page fixes.
313 Changes to Empire 4.3.5 - Sun May 28 07:49:54 UTC 2006
314 * In conditionals, ~ compared to a string selector now stands for an
316 * Change encoding of `not in any group' from " " to "". This makes
317 fleet=~ work. It also affects xdump.
318 * Fix plane capture code to clear wing.
319 * People now eat and starve exactly the same in sectors, ships and
320 land units. There used to be small differences, and civilians and
321 uw loaded on land units didn't eat at all. The starvation command
322 has been updated accordingly.
323 * Fix bug that makes it impossible to assault or board with land
324 units (broken in 4.3.4).
327 Changes to Empire 4.3.4 - Thu May 25 05:46:10 UTC 2006
328 * Don't use non-portable groff features (broken in 4.3.0).
329 * Work around potential crash bugs in command argument access.
330 * Plug major information leak through nation selectors (broken in
331 4.2.21). The fix unfortunately exchanges the meaning of xdump
332 nation and xdump country. Sorry about that.
333 * Minimize redundancy between (mortal's) xdump nation and xdump
335 * New nation selector rejects.
336 * xdump nation now shows foreign relations and no longer discloses
338 * Fix crash bug in edit.
339 * Fix number of planes building in budget command (broken in 4.3.3).
340 * Selectors group, fleet, wing and army are now strings, and obvious
341 syntax like fleet#a works. xdump also shows the strings now.
342 Units not assigned to a group currently have group string " ", but
343 that may still change.
344 * Don't fold conditionals to lower case, because it breaks valid
345 conditionals like fleet#A.
346 * Mobility cost of a plane sortie is no longer limited to current
348 * Various formulas no longer truncate or round intermediate results.
349 * Interdiction mission charged twice the normal mobility cost for
351 * Fix sail not to interpret negative x-coordinates as unsail
353 * Improved configure script.
356 Changes to Empire 4.3.3 - Tue May 16 21:35:47 UTC 2006
357 * power c can now show powerless countries. power c * works.
358 * Fortresses now require 5% efficiency to return fire and interdict.
359 * Range of ship return fire and support fire no longer depends on
361 * Fix heap smash in login command client. Remote hole!
362 * Properly destroy nukes on collapsing bridges. Before, you could
363 rescue them by building a new bridge or arming them on naval
365 * Nukes are now numbered like other units:
366 - New selector type replaces selectors number and types.
367 - New selector plane points to plane armed with this nuke.
368 - New selectors effic, mobil, tech, group, opx, opy, mission,
369 radius. Provided because all units have them; values are
370 currently not interesting.
371 - nuke command output redesigned.
372 - ndump output changed subtly: nukes are no longer sorted by
373 location, nukes in the same location no longer share id, and
374 nukes on planes are shown.
375 - transport nuke now works like transport plane.
376 * arm and disarm now accept the common plane syntax, not just plane
378 * Fix arm to let you change an armed plane's air-burst/ground-burst
380 * territory no longer re-prompts when supplied with a bad argument,
382 * edit lets you edit stuff that is actually computed from other
383 state, like sector's coastal flag. This makes no sense and is now
384 deprecated. Stuff deprecated since 4.2.15 is now gone.
387 Changes to Empire 4.3.2 - Thu Apr 27 17:59:58 UTC 2006
388 * Fix security units' raid at the update (broken in 4.0.0, fixed only
389 for 100% units in 4.2.7). Back out 4.2.7's 2.5x deadliness
390 increase. Make sure empty units don't kill anyone.
391 * Fix bug in player_init(), which was most likely fatal on 64 bit
392 hosts. Broken in 4.3.0.
393 * Fix xdump not to disclose other countries' realms (new in 4.3.0).
394 * The order in which sectors were visited for `*' arguments disclosed
395 the real origin, fix. Mapping commands used to work around this
396 bug, until 4.3.1 exposed it there as well.
397 * Code didn't compile on some systems.
398 * Fix edit plane not to truncate large values for keys 'a' and 'd'.
400 Changes to Empire 4.3.1 - Sat Apr 15 11:40:47 UTC 2006
401 * Fix check of game state on server startup (new in 4.3.0).
402 * sail now accepts a destination sector.
403 * Tend could send bogus bulletins (broken in 4.3.0).
404 * Plug memory leaks in mission command.
405 * Close loophole in navigate that allowed players to find all sectors
406 that are unfriendly or inefficient harbors or bridges.
407 * Server didn't start when default econfig was missing and user
408 didn't supply one with -e (broken in 4.3.0).
409 * Retreat condition 'h' (helpless) never worked, fix.
410 * Fix retreating mine sweepers to use mobility for sweeping.
411 * Fix retreating land units to hit mines with the same probability
412 and to take the same damage as in normal movement. Before,
413 hit probability was higher, and damage was lower.
414 * Ships could retreat into sectors owned by whoever made them
415 retreat, but not in their owner's sectors.
416 * Fix 'm' at the movement prompt of transport and test.
417 * Fix march and test not to apply conditionals to sectors mapped,
418 which led to spurious error messages.
419 * Fix break not to respect conditionals. The bug let players keep
421 * Fix retreat code not to respect conditionals. Attackers could
422 abuse this to suppress fleet and army retreat orders.
423 * Fix retreat and edit to zero-terminate retreat paths.
424 Theoretically abusable for gaining information.
425 * Fix format string crash bugs in load, spy and bomb.
426 * Fix the telegram editor: empty telegrams were broken in 4.2.21, and
427 ~p before the first line of text never worked.
428 * Fix ancient bridge building race condition that could break the
429 test whether the player can afford the bridge.
430 * Fix trade lot change detection in set command. Probably abusable.
431 * The pthread code now compiles under Solaris.
432 * navigate and march now permit any whitespace between route and
433 optional argument for radar, lookout, sonar, not just spaces.
434 * Fix canal navigation (was broken in 4.3.0).
437 Changes to Empire 4.3.0 - Sun Mar 19 08:13:10 UTC 2006
438 * version no longer pretends option SHIPNAMES still exists.
439 * Remove files auth and ban. They could be used to restrict client
440 address and user. Restricting user is useless, because players can
441 send whatever they want. Banning IPs is better done with a packet
442 filter. That leaves restricting deity IPs. Provide new econfig
443 key privip for that. Apply it to session kill as well as login.
444 * xdump escapes GUINEA_PIGS status:
445 - xdump is now enabled unconditionally.
446 - xdump sect now dumps selector coastal, because it can't be
447 reliably computed from other xdump information.
448 - New xdump realm and country. Realm information is now stored in
449 a separate file, with appropriate selectors.
450 - Reviewed for completeness and information leaks. See info xdump
451 for remaining issues. New treaty selector uid, nat selectors
452 relations, contacts. Removed useless selectors: news and lost
454 - Command syntax changed.
455 - xdump opt is no more, option information is now in xdump ver.
456 - xdump can now dump meta-data.
457 - Header and footer changed to be more compact. You now need
458 meta-data to identify fields.
460 - Documentation in doc/xdump.
461 * New econfig key builtindir.
462 * New econfig key custom_tables lets you customize configuration
463 tables without recompiling. Customizing tables other than unit
464 tables is not recommended for now. See doc/econfig for
466 * Check configuration and game state are sane on server startup.
467 * Remove option NONUKES and NEUTRON. Deities can load a suitable
468 nuke table to get the same effect.
469 * Remove option DRNUKE. Use econfig key drnuke_const to control
470 whether nukes need research.
471 * Disqualify land units from performing missions while loaded on
473 * Fix dump for strings without terminating zero.
474 * Fix login command option not to send an extra prompt.
475 * zdone now displays information about demand update vetoing.
476 * The Windows port now requires Winsock version 2.
477 * Remove econfig key powe_cost.
478 * version report now shows all the configurable settings of interest
480 * carg and lcarg now display people as well.
481 * ldump now dumps civ and uw as well.
482 * Fix dangling pointer dereference in dogfighting code.
483 * Tell sector owner when partisans take over. But don't disclose che
485 * emp_server, files, fairland now support options -h and -v.
486 * Simplify baroque version numbering to a single version number.
487 This affects output of version.
488 * New show item and show news.
490 - Follow the usual steps: configure; make; make install. The
491 latter is optional. The only file deities still have to edit is
493 - Use GNU Autoconf for system configuration.
494 - Use GNU Make for portability and features.
495 - Support separate build trees.
496 - Remake out-of-date dependencies automatically.
497 - Remake out-of-date info files automatically.
498 - Flatten info directory.
499 - Formatted info files are no longer distributed in source tarball.
500 - Use LWP only with UCONTEXT. Autoconfiguring the other LWP
501 low-level options doesn't seem to be worth the effort, as
502 UCONTEXT should be pretty portable.
503 * Fix use of freed memory in sail.
504 * sail could let large ships enter big cities.
505 * Fix reject and accept not to require contact.
506 * Fix sharebmap and telegram to prompt for a missing first argument.
507 * Fix report to align column research correctly for deities.
508 * When the optional newspaper argument doesn't work because HIDDEN is
509 enabled, complain instead of ignoring it silently.
510 * When BLITZ is enabled, fairland no longer permutes country numbers
511 in newcap_script so that start islands are ordered from top left to
513 * Minimize output format differences between options:
514 - census shows column fall regardless of FALLOUT.
515 - show nuke now shows column res regardless of DRNUKE.
516 - report no longer suppress column status when HIDDEN is enabled.
517 HIDDEN limits status information like for the country command.
518 - relations column width differed depending on option SLOW_WAR.
519 Always use the wider format.
520 * Fix a bug in edit that suppressed the player notification telex on
521 military reserve change.
522 * Fix command dispatch not to let deities use commands that are
523 declared not to be available to them. The only command affected is
525 * Fix the list command for visitor.
526 * econfig key m_m_p_d no longer applies to deities.
527 * Fix the origin command for country #0. Allow moving origin to
528 another country's origin. Allow deities to reset origin to
529 absolute 0,0. This turns origin into a superset of the offset
530 command. Remove offset command.
531 * Fix a bug that caused unpredictable flak damage when it should have
532 been maximum damage (was broken in 4.2.19).
533 * Don't store initial capital location, remove the associated nat
534 selectors xstart, ystart.
535 * Fix production command to consider resource depletion.
536 * Fix justification of coordinate output in cutoff and mission.
537 * Option UPDATESCHED is no longer optional. Disabling it didn't
540 * Turn options into ordinary econfig keys.
541 * New econfig key start_cash.
542 * BTU regeneration now depends on the capital's work percentage.
543 * nation now supports an optional argument that lets deities ask for
544 somebody else's nation report.
545 * Fix nation to display SANCTUARY instead of VISITOR for countries in
547 * Fix capital to let you use a regained sacked capital without
548 activating another one in between.
549 * Don't move capital when it is sacked.
550 * New ship capability canal, replacing obscure formula based on build
552 * You now need a capital to request a demand update.
553 * power now ignores landspies.
554 * Fix LWP stack checking.
555 * Clean up LWP, drop dead machine-specific code, fix portability bugs
557 * census now shows the old owner instead of `*'. dump is unchanged
558 to avoid breaking clients.
559 * peek no longer prints the old owner.
560 * When a bombed land unit retreated, collateral damage was applied to
562 * paradrop, drop and fly can no longer abandon the base sector.
563 * Tending foreign ships now sends a bulletin to the owner.
564 * Fix bug that permitted login for inactive countries, including ""
565 * Fix tend for spies.
566 * Change launch to fire all missiles selected at the same target.
567 Previously, it prompted for a new target after each missile.
568 * add, consider, build, launch and fire no longer re-prompt when
569 supplied with a bad argument, they just fail. Consequently, the
570 build command no longer lets you list types you can build. It
571 points to the show command instead.
572 * Fix add not to truncate country number.
573 * Fix selector coastal to be accurate at all times.
574 * Fix obscure bug in fairland: the sector added last to an island
575 wasn't considered coastal. Affected resource computation.
576 * Fix sector wiping in add command.
577 * Remove options NO_LCMS, NO_HCMS, NO_OIL. They were broken in many
578 ways. Custom configuration tables should become a serviceable
579 replacement eventually.
580 * Client no longer freezes on long lines of server output.
581 * Fix uninitialized signal mask bugs.
582 * Fix Windows service code's treatment of -e.
583 * Sub interdiction disclosed sub owner through news' actor selector.
584 * country reports on all countries, but carefully limits information
585 disclosed to mortals. Output format changed.
586 * Market no longer forces sellers to grant loans.
587 * Fix potential crash bug in set command. Friendlier prompt and
589 * Substantial code cleanup and portability fixes.
590 * Extend empfile abstraction to cover game configuration.
591 * Overhaul of game state storage.
592 * The above includes major contributions from Ron Koenderink. Many
595 Changes to Empire 4.2.23 - Sun Oct 23 09:28:26 UTC 2005
596 * Make version pretend option SHIPNAMES still exists, for the benefit
597 of clients that still depend on it.
598 * The change to conv in 4.2.22 could crash or compute incorrect
600 * Info updates missing in 4.2.22.
601 * A few code cleanups.
603 Changes to Empire 4.2.22 - Tue Oct 11 20:23:51 UTC 2005
604 * Log player login, logout and session kill.
605 * Close loophole in assembly point rules that allowed players to find
606 all unowned sectors. The assembly point must now be owned by you
607 or an ally, or you or an ally must have a ship there.
608 * Don't let embarked land units fire flak.
609 * Fix display of the last connection's host when the host name was
611 * Fix change command to accept full length representative (password),
612 currently 19 characters. It used to chop off after eight
614 * Non-recon missions no longer establish contact to owners of
615 overflown sectors, because those missions do not identify the
616 owner. This matches info Hidden.
617 * The following events now establish contact:
619 - Sighting a ship when toggle coastwatch is off
620 - Spotting overflying planes
621 - satellite spotting land units
622 - lookout and llookout spotting ships, planes and land units
623 - Any relations change
624 * The country command's `temporary' state of disorder ended after
626 * Telegram notifications could get lost in exotic circumstances,
627 e.g. while a second client attempted to connect. Abusable.
628 * Remove option SNEAK_ATTACK.
629 * Fix lboard not to let you board dead land units.
630 * Fix stack smash in bomb, drop, fly, paradrop, recon and sail.
632 * bomb, drop, fly, paradrop, recon and sail now deal with EOF
634 * Fix fly to let the player abort the command at the last prompt.
635 * Client no longer reads execute scripts in binary mode under
637 * New econfig key listen_address.
638 * econfig key port can now be a service name. Service empire no
639 longer takes precedence over econfig.
640 * Client falls back to compiled-in host only if environment doesn't
641 supply one, not if it can't be resolved. Same for port.
642 * Oil derrick could extract slightly more oil than was in the ground.
643 * test command checked start sector for space and some other things
644 instead of end sector.
645 * convert now silently limits conversions to avoid exceeding maximum
647 * shoot no longer limits you to 999 victims.
648 * 4.2.19 broke pin bombing commodities on some platforms.
649 * Don't block on output while update is pending. This is required to
650 ensure the update can abort commands.
651 * Commands submitted while the update is waiting for commands to
653 * The force command no longer waits for the specified time. It
654 starts a scheduling thread instead, just like shutdown.
655 * Correct grammar and punctuation in output of version.
656 * Option SHIPNAMES is no longer optional.
657 * Fix output of qorder and sorder for ships with sail path.
658 * Don't change capital to agribusiness on retake. From Pat Loney.
659 * bdes prompt for new designation was messed up for empty bmaps.
660 * Client now supports pipes under Windows.
661 * Care for subtle Windows socket incompatibilities.
662 * Fix strength command not to lie about units reacting into
664 * strength now yields the processor periodically, to keep the game
666 * Schedule commands more fairly. Previously, a sufficiently fast
667 player could starve out the others.
668 * launch assumed plane maximum mobility 127 for calculating when
669 satellites will be ready to use.
670 * Drop support for for DCE threads.
671 * Drop support for pthread implementations lacking pthread_kill().
672 This includes ancient versions of OS X.
674 * Minor info file fixes.
675 * The above includes major contributions from Ron Koenderink. Many
678 Changes to Empire 4.2.21 - Sat Jul 16 17:51:01 UTC 2005
679 * Don't let threads block on output to another player thread's
680 socket. Such blocking violates basic design assumptions and can
681 cause all kinds of grief. In particular, it causes player session
682 hangs under Windows with 4.2.20. Broken since the introduction of
683 flash and asynchronous telegram notification many years ago.
684 * Threads sleeping until a specified time could return early under
685 Windows. This could cause double-updates.
686 * Fix fallout damage (was broken in 4.2.19).
687 * Fix show sector s (was broken in 4.2.19).
688 * Fix deliver not to deliver friendly civilians into occupied
690 * Fix mil duplication in board (was broken in 4.2.14).
691 * Fix stack smash in lrange, shoot and execute. Remote holes, and
692 the last one doesn't even require authentication.
693 * Fix crash bug in emp_config parsing.
694 * Fix buffer overruns in turn and shutdown.
695 * Fix second argument of shutdown.
696 * tele and turn now abort on EOF.
697 * Fix display of MOTD and game down message of maximum size.
698 * Correctly support telnet line termination on input. Previously,
699 carriage returns could slip into ship names and such.
700 * Fix flash not to lie about recipients that are just logging in.
701 * Remove obscure login command list.
702 * Convert client from obsolete termcap to terminfo, and clean up
704 * New fairland option -h to print usage information. Improved
705 command line syntax diagnostics. Exit unsuccessfully on unknown
707 * fleet and army now copy retreat orders of the fleet's or army's
708 first member with group retreat orders in the same sector.
709 Previously, they used the retreat orders of the first fleet or army
710 member, which is less than useful, and failed to take ownership
711 into account, which is an abusable bug.
713 * Fix xdump not to disclose other countries' losses.
714 * Fix exit status of files program when it can't create files.
715 * Support UTF-8 encoded Unicode in human-human communications. This
716 affects MOTD, game down message, telexes, announcements and flash
717 messages. See new doc/unicode for technical details.
718 * New login command `options' for client/server option negotiation.
719 See new doc/clients-howto for technical details. The only option
721 * emp_client -u now requests UTF-8. This requires a terminal that
723 * Fix news for land unit defensive support.
724 * Properly mark sea mines hit by retreating ships. Unmark mines
726 * Fix diagnostics for unknown selector names in conditionals (was
728 * Fix selector name clashes: rename ship selector mobquota to mquota,
729 land selector for reaction range limit from rad to rmax.
730 * Fix Windows services for relative file names on command line or in
731 econfig (was broken in 4.2.20).
732 * econfig keys ship_grow_scale, plane_grow_scale and land_grow_scale
733 are now float. This gives deities finer control over maximum
735 * Fix production command for sectors with 60% efficiency.
736 * Improve syntax of read for deities.
738 * Some info topic names differed only in case, which loses on
739 case-insensitive file systems, and is a bad user interface even
740 when it works. Change those names. Rename deity command hidden to
741 peek because its info topic clashed with that of option HIDDEN.
742 * Thanks to Doug Wescott sheep are finally covered properly in info.
743 * Documentation fixes.
744 * Much of the above was contributed by Ron Koenderink. Many thanks!
746 Changes to Empire 4.2.20 - Tue Mar 22 21:07:18 UTC 2005
747 * When units in different sectors marched, only units in the sector
748 with the highest-numbered unit were interdicted. A marching
749 non-spy made all marching spies visible to interdiction regardless
751 * Fix crash when interdiction sinks second ship in a sector. Broken
753 * Fix an ancient bug in simulation of level production that clobbered
754 stack and could lead to low predictions, typically zero, which
755 screwed up budget. The bug had no effect until 4.2.19.
756 * When a sector revolts, and there wasn't enough space to liberate
757 all uw, the number of remaining uw got the wrong sign. Broken in
759 * Log and abort when LWP stack check detects stack smash. Server
760 option -s no longer implies -p.
761 * The native Windows build now supports -p and -s.
762 * The native Windows build now properly deals with ^C when running in
763 the foreground. It no longer prompts for a quit command on the
765 * The meaning of server option -D in presence of -e is unclear.
766 Other programs only support -e. Remove option -D. Use -e
767 DIR/econfig instead of -D DIR.
768 * New server option -v shows version information.
769 * Fix the server's exit status with -h. Broken in 4.2.19.
770 * The linux-pthreads build failed to shut down on signals.
771 * Fix threading bugs in the native Windows build that made shutdown
772 unsafe and screwed up update aborting commands.
773 * New econfig key pre_update_hook to allow automatic, safe backup
774 right before the update. See scripts/backup for an example.
775 * The server now prints log messages to stderr as well when running
777 * Fix potential buffer overflows in logerror() and lwpStatus().
778 * Server now requires POSIX signals. It no longer catches SIGUSR1.
779 * Remove support for ancient versions of HP-UX.
780 * Fix seeding of PRNG broken in 4.2.19.
781 * Don't reseed the PRNG in commands, it hurts randomness and could be
782 abused by crafty players.
783 * The server now makes the data directory its working directory.
784 This also gets rid of a bug that changed the file name of the
785 sector, power, nation and lostitems file unless econfig could not
787 * The server now writes a pid file. Thanks to Daniel O'Connor.
788 * More user friendly server startup: more errors are detected while
789 the server still runs in the foreground, which makes it possible to
790 complain to stderr and to exit unsuccessfully.
791 * Early log messages went to the log file in the default data
792 directory, even though econfig specifies another data directory.
793 * Specifying an econfig file on the command line that can't be read
795 * Errors in econfig are now fatal.
796 * The server now refuses to start when it can't open data files.
797 * News are now sorted and expire sanely.
798 * Conditionals can now compare strings as well.
799 * Corrupted down and motd files could cause buffer overflows.
800 * Fix recon to let player abort at the flight path prompt.
801 * power no longer rounds worldwide numbers for deities.
802 * power command failed to recognize deities with non-zero country
804 * Change output of production command so that columns are aligned
805 even for large values. Replace column wkfc by more useful column
807 * neweff and production miscalculated work when mil exceeded
809 * neweff miscalculated work when the population limit exceeded 999.
810 * Fix capping of avail when a big city is torn down.
811 * Fix a bug in fire that allowed players to find all submarine uids.
812 * Maximum sector population is no longer hardcoded, and now covered
813 by xdump. Option RES_POP now affects mountains and plains as
814 well. From Ray Hyatt.
815 * Fix fina and news not to ignore errors in conditions.
816 * The native Windows build now requires Windows Sockets 2.
817 * The native Windows build now supports multiple instances of the
818 service. The ability to supply additional startup parameters to
819 the service has been removed.
820 * Implement fairland command line parsing under Windows.
821 * Improved fairland and emp_server usage message.
823 * Minor info file and documentation fixes.
824 * Much of the above was contributed by Ron Koenderink. Many thanks!
826 Changes to Empire 4.2.19 - Thu Dec 23 20:24:24 UTC 2004
827 * Fix order not to unload into full sectors.
828 * Fix scrap not to dump stuff into full sectors. Excess stuff is now
830 * Fix distribute not to conjure up a civilian when importing
831 civilians from a dist center that doesn't have any.
832 * Fix flak to resupply no more shells than actually needed.
833 * Fix rounding error in shoot that could result in more people shot
835 * Fix info and apro error handling. In particular, do not leak
836 potentially sensitive information on the server to players.
837 * info no longer shows a random matching page when the topic argument
838 is ambiguous. Instead, it lists all matching topics.
839 * Embarked land units and overflying planes no longer spot each
841 * Fix show command to show only sectors that players can designate
842 (was broken in 4.2.18).
843 * Fix a rounding error in production command column `max'.
844 * Fix production command for overpopulated mountains and plains.
845 * Fix tradeship ally cut to match documentation.
846 * Fix plague, which was was broken in 4.2.14: it got stuck in stage I.
847 * Fix a bug in aerial sonar where ships could mask submarines with
848 the same number modulo 256.
849 * Don't allow bombing of subs that were not detected.
850 * MOTD and the game down message are now entirely separate: use `turn
851 motd' for the MOTD, and `turn on' and `turn off' for the game down
852 message. `turn on' no longer lets you edit the MOTD.
853 * Remove option NUKEFAILDETONATE.
854 * Option ORBIT is no longer optional.
855 * New option GUINEA_PIGS to control experimental stuff not ready for
856 prime time. If your deity enables this in a serious game, run!
857 * Many xdump fixes. xdump is now enabled by option GUINEA_PIGS.
858 * New ship and land selectors rflags, rpath.
859 * New ship selectors for order: xstart. xend, ystart, yend,
860 cargostart, cargend, amtstart, amtend
861 * New ship selectors for sail: mobquota, path, follow.
862 * New news selector uid.
863 * Implement command line parsing under Windows where it was missing.
864 * emp_server and and files print a usage message on command line
866 * Fix how emp_server exits after being panicked by a signal. It can
867 now dump core when this happens.
868 * Fix bug in client that could crash it when a line of input starts
870 * Client now gets user name from environment variable LOGNAME if set,
872 * The native Windows build can now run as a service.
873 * Redirecting client input now works under Windows.
875 * Don't confuse work with loyalty in info Citizens.
876 * Minor info file and manual page fixes.
877 * Much of the above was contributed by Ron Koenderink and Marc
878 Olzheim. Many thanks!
880 Changes to Empire 4.2.18 - Tue Sep 7 14:08:59 UTC 2004
881 * Fix info to accept abbreviated arguments under Windows. From Ron
883 * Buying planes or land units loaded on something didn't work when
884 that something moved.
885 * Fix a bug that could produce update cascades with update policy
887 * Fix delivery and distribution to grant packing bonus only to
888 efficient sectors, just like move. Previously, delivery ignored
889 efficiency, and distribution behaved as if it were an efficient
890 sector without special bonuses.
891 * New sector selectors loyal, access; ship selectors radius, access,
892 xbuilt, ybuilt, builder, name; plane selectors radius, access,
893 theta; land unit selectors radius, react, nland, access; lost
895 * Fix sector selectors che, che_target; plane selectors att, def;
896 nuke selector types; treaty selector exp; news selector time;
897 commodity selectors type, xbuy, ybuy.
898 * Option PLANENAMES is no longer optional.
899 * Ensure config parameter variables and their description in
900 configkeys[] are consistent. Inconsistencies there caused bugs in
901 the past. From Marc Olzheim.
902 * Complain if econfig file can't be read.
903 * Better messages for errors in econfig file.
904 * Remove unused econfig keys hard_tech and last_demand_update.
905 * New econfig key news_keep_days to configure news expiry.
906 * New econfig key anno_keep_days to configure announcement expiry.
907 * Fix announcement expiry. It leaked file descriptors and memory,
908 and could corrupt the anno file. From Ron Koenderink.
909 * New command xdump: experimental extended dump. Disabled for now.
910 * Bankers no longer round down debts, and they collect interest for
911 the time debtors are idling at sub-prompts.
912 * Loan interest calculation was broken at the due date and after a
913 last payment made at the due date. With luck, debtors could abuse
914 this to repay loans cheap (they couldn't gain cash, though), sharks
915 to purchase loans cheap, and creditors to collect excessively.
916 * Fix major bug in transport that allowed two cooperating countries
918 * Don't report interdiction damage twice when transporting planes.
919 * Fix message for attempting to transport a plane in a sector not
921 * Fix confusing diagnostics when refusing to improve defense because
922 option DEFENSE_INFRA is off.
923 * Simplify confusing code in budget.
924 * Fix spacing in output of budget and show.
925 * Change one-way plane sorties to match ordinary sorties: offer
926 carriers regardless of the sector they're in, require carriers to
929 * Don't print owner of incoming missile twice when intercepting it.
930 * Simplify constituent storage in product characteristics.
931 * Replace remaining `variables' leftovers; mainly in unit
933 * Remove leading spaces in deity unit dumps.
934 * Replace inappropriate uses of compile time constant ETUS by 60.
935 Deities don't change ETUS, they change etu_per_update by editing
936 econfig. This nonsense dates back at least to chainsaw 3.31.
937 * Change ship production (fishing and drilling for oil) to match
938 sector production. Ship efficiency and tech are now relevant, and
939 all people on board work. From Ron Koenderink.
941 * Minor info file fixes.
943 Changes to Empire 4.2.17 - Mon Aug 16 16:21:53 UTC 2004
944 * Fix seeding of PRNG under Windows. The bug made updates occur at
945 a predictable time in the update window. From Ron Koenderink.
946 * Close major loophole in drop that allowed players to determine
947 whether an arbitrary sector is sea, allied land, or other land.
948 * fly could fly civilians into occupied sectors. For consistency
949 with other means to move around stuff, this is no longer possible.
950 * Don't allow flying to a carrier that doesn't have space for the
951 planes. Previously, planes that did this were teleported home,
952 which could be abused.
953 * Close loophole in bomb that allowed players to find all
955 * Fix move and explore not to crash when moving civilians to a sector
956 without civilians, and interdiction destroys them all. Found and
957 debugged by Jeff Cotter.
958 * Fix printing of messages entered with turn command. '%' characters
959 could cause havoc, even crashes.
960 * Use sector's actual maximum population to compute chance of plague
961 outbreak. Previously, code used 9999 for big cities and 999 for
962 other sectors, and info Plague said 999. This makes all crowded
963 sectors equally vulnerable, even mountains, plains, and inefficient
965 * Oil derricks no longer drill and deplete more oil than they can
966 hold. From Ron Koenderink.
967 * Version 4.2.15's coordinate and list parsing fixes reject trailing
968 junk. That's too strict. Silently ignore trailing junk as long as
969 it starts with whitespace.
970 * Version 4.2.15's selector rewrite broke some type literals,
971 e.g. `?des=n' was interpreted as `?des=newdes'. Change to prefer
972 type literals to selectors.
973 * Nightly build patches game to get repeatable PRNG results. From
976 Changes to Empire 4.2.16 - Wed Jun 16 18:56:16 UTC 2004
977 * Previous version broke sector production when part of the work is
978 used for sector construction. Fix courtesy Jeff Cotter.
979 * Add rudimentary tests to nightly build. From Marc Olzheim.
981 Changes to Empire 4.2.15 - Wed May 26 17:55:58 UTC 2004
982 * test command no longer asks whether to abandon the sector.
983 * explore command could generate a bogus `lost' record when it
984 regains an abandoned start sector.
985 * edit command now properly updates stats when editing tech level of
986 ships, planes or land units. A few of these stats can be edited
987 separately, which doesn't make much sense, and is now deprecated.
988 * edit command no longer accepts efficiency values that would destroy
989 the edited unit. Deities can still delete units by setting the
991 * upgrade command used to charge an amount of avail that didn't match
992 info upgrade. Neither the implemented nor the documented amount
993 made much sense. Change it to 15% of the full build cost. Rewrite
995 * Commands upgrade and build could be off by one when reporting
997 * upgrade command reported rounded cost but charged unrounded
998 cost. Round cost of upgrade down to match behavior of build.
999 * Upgrading planes now preserves range when it is less than the
1000 maximum range. It used to set it to the new maximum range.
1001 * show bridge and show tower no longer claim bridge building requires
1002 `workers' (whatever that is), since it doesn't.
1003 * Replace option ROLLOVER_AVAIL by econfig parameter
1004 rollover_avail_max, which is the maximum amount of avail that rolls
1005 over. Previously, avail was limited after rollover, and even when
1006 ROLLOVER_AVAIL was off. Fix that.
1007 * Ships weren't always charged mobility for firing with option
1009 * Fix shell use of return torpedoes.
1010 * designate no longer complains twice about deity only designations.
1011 * Ensure designate zaps efficiency only when sector type really
1013 * Fix strength to always report mines to deities.
1014 * Remove option SHIP_DECAY.
1015 * Fix bug in sonar that could crash or yield unpredictable results
1016 near the true origin.
1017 * Fix buffer overflow in flash and wall.
1018 * Fix wall not to strip out first word of message.
1019 * Change market and order to use item types instead of mnemo
1020 characters internally.
1021 * Market now reports sales with full item names instead of single
1023 * buy now requires first argument to be an item name, as documented.
1024 * production command handled production backlog incorrectly, failed
1025 to limit production for production efficiency greater than one,
1026 e.g. agribusiness, and incorrectly limited raw material
1027 consumption. Also fix a rounding error. With help from Ron
1029 * Sector work was accidentally truncated to even.
1030 * Fix coordinate parsing for large numbers when WORLD_X or WORLD_Y
1031 don't divide SHRT_MAX+1.
1032 * Properly diagnose over-long unit lists.
1033 * Rewrite selector code. Old code let players smash the stack by
1034 supplying too many conditions. New code properly rejects ambiguous
1035 abbreviations and prefers exact matches. Selectors with names that
1036 collide with types, like land units' rad and spy, now work. Selectors with
1037 non-integral values, like land units' att, now work.
1038 * survey used to display hundreds for everything but variables. Now
1039 it displays hundreds only for values that can be large.
1040 * Rewrite info survey. Document ability to survey properties other
1041 than items and resources.
1042 * Rewrite info build, since it was inaccurate and poorly structured.
1043 * Fix info fire on required military. From Marc Olzheim.
1044 * New fairland argument -R to set the PRNG seed. Print the seed.
1045 This allows you to recreate the same world again.
1046 * New facilities to deal with internal errors. These crash when the
1047 server is started with -d, which is appropriate for debugging, and
1048 potentially disastrous for running a real game.
1049 * Automated nightly builds.
1052 Changes to Empire 4.2.14 - Mon Mar 22 09:04:12 UTC 2004
1053 * Options NEWPOWER, NEW_STARVE and NEW_WORK are no longer optional.
1054 * Gripe about unknown options in econfig.
1055 * Remove option GRAB_THINGS.
1056 * Utility program files takes new option -f.
1057 * Remove utility programs land, ore and perfect, which don't compile
1058 since 4.2.0 (Oct '98).
1059 * fairland no longer warns when it added resources, but when it
1061 * Fallout code could claim destruction of more items than actually
1063 * Fix recursive resupply (resupply from supply land unit triggering a
1064 resupply of the land unit) when just testing for how much can be
1065 resupplied. The bug could have led to insufficient resupply.
1066 * Fix recursive resupply not to consume all fuel in supply units. No
1067 supply units consuming fuel exist in the stock game.
1068 * Limit delivery and distribution thresholds to ITEM_MAX (9999).
1069 Distribution threshold were previously limited to 10000, and
1070 delivery thresholds to 65528.
1071 * Limit items in sectors to ITEM_MAX (9999). Commands give and buy
1072 used to limit to 9990. Market transactions and commands explore,
1073 move, drop and fly to 32767. Limiting in autonav code (order
1074 command) didn't work. Item delivery used to stop at 9990,
1075 distribution at 9999. Food growing and sector production used to
1076 stop at 9999. Grind, assault lunchboxes, demobilization, mine
1077 sweeping and che liberating uw could theoretically attempt to
1078 increase items beyond 65535, which would have been ignored
1079 (destroying the increase).
1080 * Properly saturate fallout at FALLOUT_MAX (9999). Previously,
1081 fallout increases behaved inconsistently. Increases beyond 65535
1082 could get ignored, or fallout could saturate at 9999, or it could
1083 overflow at 65536 (that would take quite some nuking, though).
1084 * Properly saturate mines at MINES_MAX (65535). Previously, a mining
1085 operation that would have gone beyond 65535 was ignored.
1086 * Fix `are we loading or unloading' tests for load, unload, lload and
1088 * Fix editing of land unit attack and defense values. Implement
1089 editing of ship defense values. Contributed by Ron Koenderink.
1090 * edit now edits che number and target separately.
1091 * Fix edit to properly extend unit files. Contributed by Ron
1093 * Major internal reorganisation: Sectors need space for items,
1094 deliveries and distribution thresholds. To save space, the
1095 ancients invented `variables': a collection of key-value pairs,
1096 missing means zero value, space for `enough' keys. This
1097 complicates the code, as assigning to a `variable' can fail for
1098 lack of space. Over time, `enough' increased, and for quite some
1099 time now `variables' have been *wasting* space. Replace them,
1100 except in unit characteristics, where they are read-only, and will
1101 be replaced later. This also removes misfeatures like plague
1102 outbreaks silently deleting deliveries.
1103 * Remove disabled commands dissolve and mult. Remove configuration
1104 parameters minmult and maxmult.
1105 * trade command indexed an array out of bounds when attempting to
1106 display the plague as commodity. Fix.
1107 * New make goal interix. Contributed by Ron Koenderink.
1108 * The type selector now prefers an exact match to a partial match.
1109 ?type=sb now selects sb, not sbc, even when sbc happens to be found
1111 * Value of selector sell was always zero, remove it.
1112 * Clean up selector code.
1113 * satellite now displays all sectors owned by other players, and none
1114 else. It used to display all but sea, mountains, sanctuaries,
1115 wasteland and wilderness.
1116 * map commands now display wilderness and plains owned by other
1117 players as '?'. Radar commands now display all wilderness and
1119 * Fix power timestamp for Windows. Contributed by Ron Koenderink.
1120 * Make client abort the current command on ^C under Windows, as
1121 everywhere else. Contributed by Ron Koenderink.
1122 * Command line parser interpreted trailing whitespace as an another
1123 (empty) argument. Ignore it instead.
1124 * Properly declare stuff in headers, include proper system headers.
1125 Remove all nested external declarations. Source code is now fully
1126 prototyped. Enable appropriate gcc warnings.
1127 * Fix several type errors. Some may have been show-stoppers on big
1128 endian machines where sizeof(long) != sizeof(int).
1129 * Remove pre-ISO C compatibility cruft (hey, it's been only fifteen
1131 * Various portability fixes. Some bugs may have been show-stoppers
1132 when sizeof(long) != sizeof(int). With help from Marc Olzheim and
1134 * Move some code to more logical places. Remove some unused code,
1135 some of which was hard to port.
1136 * The files program could print error messages to a log file in some
1137 circumstances. Make it print to stderr.
1138 * deliver can now change direction without changing the threshold.
1139 * deliver now provides appropriate context when prompting for
1141 * Login command play no longer ignores up to two arguments if there
1143 * Fix payoff (was broken in 4.2.13).
1144 * Capability fish didn't work together with capability oil.
1145 * Fix and clarify plague outbreak chance in info Plague.
1146 * Fix RES_POP maximum population in info Research.
1147 * Fix info telegram and info announce on ~ escapes.
1148 * Update info Selector to match code.
1149 * Document all undocumented unit capabilities and stats.
1150 * Document submarines' ability to carry landspies.
1151 * Fix info shoot on security units.
1152 * Various small info file fixes.
1153 * Many fixes in the troff macro package for info files.
1154 * Many fixes for translating info files to HTML.
1155 * Many info file markup fixes.
1157 Changes to Empire 4.2.13 - Fri Feb 13 22:12:36 UTC 2004
1158 * Source code reindented and cleaned up somewhat.
1159 * Various small info file fixes.
1160 * Fixed change requiring 254 BTUs even when not charging any
1162 * Fixed tactical non-marine missile crash.
1163 * Fixed spy unit detection chance for eff<100.
1164 * Fixed output of sorder.
1165 * `edit' can now work non-interactively. Contributed by Ron
1167 * Fixed and extended edit for sectors.
1168 * Fixed use of errno.
1169 * Minor security fix: doconfig now writes example auth entry as
1171 * Fixed reading of country name and password in client for Windows.
1172 * Replace use of some obsolete non-portable library functions by
1173 portable equivalents.
1174 * designate now warns about redesignated capital only when it
1175 succeeds in redesignating the capital.
1176 * attack could be off by one when reporting required unit mobility.
1177 * Fixed command matching. Unique prefixes were not always
1178 recognized, and junk suffixes were ignored.
1179 * Removed bestdistpath. bestpath yields the same results.
1180 * Renamed lstats to lstat for consistency and to match info page.
1181 * Fixed non-portable fd_set * arguments of select().
1182 * New `map' flag `h' to highlight own sectors. Contributed by Marc
1184 * Fixed `sabo' reporting damage to player in deity coordinates.
1185 * New option ROLLOVER_AVAIL. Contributed by Drake Diedrich.
1186 * Fix Windows server shutdown on reading "quit" from stdin.
1187 * Land units now fortify automatically when mobility plus growth
1188 exceeds the maximum. With code from Marc Olzheim.
1189 * Wandering che are less predictable.
1190 * Land units no longer regenerate mobility faster while it is
1192 * Fixed emp_client -k.
1193 * No longer allow pirates to ferret out where a ship was built.
1194 * Fixed map commands to reject bmap flags `t' and `r' instead of
1196 * Fixed lmine shell resupply.
1197 * News no longer call all sub-launched missiles nuclear.
1198 * Incoming missiles are now reported with coordinates.
1199 * Removed some code that served no purpose except crashing on
1201 * Fixed Mac OSX and AIX build problems.
1202 * Don't resolve player IP addresses for now, because it can crash
1203 with certain versions of GNU libc.
1204 * Fixed recording of lost nukes.
1206 Changes to Empire 4.2.12 - Mon Aug 18 16:54:21 MDT 2003
1207 * Corrected contact information for Wolfpack.
1208 * Sector isn't abandoned until move or explore is complete.
1209 * Fixed multiple cases where return value of getstarg() was
1210 used without being checked which crashed the server.
1211 * Used stdarg.h instead of varargs.h.
1212 * Call only_subs and save result before mission frees attacker
1213 list. Call with free list could cause server crash.
1214 * Fixed spy sat map for units on opposite side of world wrap.
1215 * Don't sleep in main thread when called from signal handler.
1216 * Fixed error checking in pthreads.
1217 * Properly detach pthreads.
1218 * Pass unlocked mutex to pthread_mutex_unlock.
1219 * Cope with interrupted sleep in pthread empth_sleep to prevent
1221 * Added server configurable update window.
1222 * Initialized variables passed to setsockopt in accept.c.
1223 * Fixed bug where sharing bmap with uncontacted country crashes
1226 Changes to Empire 4.2.11 - Sun Sep 1 09:54:59 MDT 2002
1227 * Added compile option for the Mac OSX architecture.
1228 * Fixed bug in cargo where unit array was indexed by shp_maxno
1229 instead of lnd_maxno.
1230 * Fixed bug in reject where aborting the command crashes the
1232 * Can't buy land units into enemy headquarters.
1233 * Added sabotage command and commando unit.
1234 * Spies moving by themselves will not trigger interdiction.

1237 * Ships going under -127 mobility will be set to -127 mob and
1238 not roll over to positive mobility.
1239 * Corrected plane cost in info Maintenance.
1240 * Changed error message for loans rejected for being too big.
1241 * Land units will take casualty damage proportional to their
1242 ability to carry mil.

1253 wouldn't be kicked off during long flashes or writing telegrams.
1254 * LOSE_CONTACT will work as advertised.
1255 * Allied units marching through 0 mobility conquered sectors
1256 are charged at least LND_MINMOBCOST.

1259 * Assault can reinforce own sector when SLOW_WAR is enabled.
1260 * emp_client no longer converts lines into tags but still verifies executes,
1261 pipes, and file redirect match players input.
1262 * Added pboard command to capture enemy planes in your territory.
1263 * Declaring war when at Sitzkrieg won't return relations to Mobilizing.

1286 * Fixed range in radar.t and Sector-types.t. Maximum range at infinite
1288 * Changed so that player can't drop civilians into occupied sectors.
1289 * Fixed bug that crashes update if etus/update is less than 8.
1290 * Fixed sometimes not reporting overflights
1291 * Fixing flak for units/ships to be in all sectors as they should be
1292 * Updated order of firing flak in Flak.t.
1293 * Fixed 80% efficient planes on ships must be maintained.
1294 * Fixed initial MOB_ACCESS check thread sleep time was set by an uninitialized

1306 * Option MARKET is turned off by default.
1308 Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
1309 * Added new NF_SACKED flag to indicate when a country has had it's
1310 capital sacked. This flag is only cleared when the country actively
1311 redesignates it's capital using the "capital" command, and changed
1312 capital.t to reflect this (no more re-sacking after an update if the
1313 country doesn't reset and repeating until they are out of cash.)
1314 * Added land unit to edit command for planes.
1315 * Added nuketype to edit command for planes.
1316 * Changed so that if the leader of a group of units is a train, the
1317 railways are used for bestpath instead of roadways.
1318 * Changed mission command to also print reaction radius of reserve
1319 missions when set for land units.
1320 * Changed Flak.t to reflect guns having to be loaded onto a land unit
1322 * Changed so that visitor countries cannot change their name or password.
1323 * Changed so that you cannot upgrade deity planes, ships or units.
1324 * Changed so that you know where missions are flown from.
1325 * Changed so that the airport owner you fly a mission from is informed.
1326 * Changed so that preperations for takeoff are reported to the owner of
1327 the sector, ship or unit a plane is taking off from if it is not owned
1328 by the owner of the plane.
1329 * Changed so that when a sector reverts during a guerrilla revolt, the
1330 mobility is not reset. When MOB_ACCESS is not enabled, this used to mean
1331 you would always get at least an updates worth of mobility. With
1332 MOB_ACCESS, sectors that reverted during the update were useless, since you
1333 got no mobility for a long time. This fixes that problem, and makes che
1334 more useful as well.
1335 * Changed so that air defense missions don't always send up every plane in the
1336 area, but instead always send up at most two times the number of incoming
1337 planes (for each interdicting country.) This helps to stop 1 plane from
1338 stripping the mobility from 25 air defense planes all at once, but doesn't
1339 limit it to n+1 as there is for regular interception.
1340 * Clarified deity reversion of sectors in Sector-ownership.t
1341 * Clarified production efficiency and added pointer to "show sector cap"
1343 * Clarified nuketype selector for planes in Selector.t
1344 * Clarified that fortifying units does not affect mission status in info
1345 pages for mission and fortify.
1346 * Clarified fuel syntax upon error in fuel command in empmod.c.
1347 * Cleaned up comments causing minor complaints in some builds.
1348 * Fixed bug in loans where you could collect on proposed loans.
1349 * Fixed production command to be more accurate (though it *still* has some
1350 rounding errors, it's better.)
1351 * Fixed potential memory leak in air defense missions.
1352 * Fixed bug where you couldn't pinbomb some commodities if other commodities
1353 didn't already exist in the sector.
1354 * Fixed bug where you couldn't build 0 crew planes without military in the
1355 sector. (This is different from needing at least 1 military to build all
1356 planes that need a crew which introduced another related bug earlier.)
1357 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
1358 messages to be displayed for deity owned planes.
1359 * Fixed bug where land units on ships in a sector taken over were blown
1361 * Fixed bug where planes on ships in a sector taken over were blown up
1363 * Fixed bug in sdump printing origx and origy in deity coordinates.
1364 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
1366 * Fixed bug in launch showing wrong satellite target (showed asat instead
1367 of the target satellite.)
1368 * Fixed bug where you could gain information not normally available using
1369 the "fire" command to determine sector type information.
1370 * Fixed bug in market/trade creating extra money when loans are taken out.
1371 * Fixed problem with land units not being reported sunk after being sunk
1372 on a ship that was nuked or wastelanded in a sector.
1373 * Fixed problem with Spies.t using "llook" instead of "llookout".
1374 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
1375 on some Linux boxes.
1376 * Fixed problem with plague infection being way too high in cities when
1377 the BIG_CITY option is enabled.
1378 * Fixed bug in edit command getting confused with arguments.
1379 * Fixed bug in ask_move_in_off asking you to move in a negative number of
1380 troops (hey, it could happen. :) )
1381 * Fixed bug in add command not keeping flags or relations initially correct.
1382 * Fixed bug in torpedo command sometimes telling victim about torpedo
1383 sightings even when way out of range.
1384 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
1385 as not formatting them properly when reporting them.
1386 * Fixed bug in satellite with noisy transmission causing a potential
1387 crash of the server with non-100% efficient satellites.
1388 * Fixed potential crashing of the server during satellite display when not
1389 calculating distances to ships and units correctly.
1390 * Fixed bug where planes in non-allied sectors, ships and units could be
1392 * Fixed bug where planes on the trading block could be used on missions.
1393 * Fixed bug where planes and units that get traded don't have mobility set
1394 correctly when using MOB_ACCESS option.
1395 * Fixed bug which made security units virtually useless.
1396 * Fixed access times and mobility not being set right when building planes,
1397 ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
1398 * Fixed minor formatting problem with launch of satellites.
1399 * Fixed minor formatting problem with planes with greater than 999 tech.
1400 * Fixed minor formatting problem with ships with greater than 999 tech.
1401 * Fixed problem with "llook" showing up in TOP info file.
1402 * Fixed problem with lwp Makefile choking on NT builds with clean target.
1403 * General cleanup of potentially ambiguous statements.
1405 Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999
1406 * Added "TECH_POP" as an option where technology costs more to make
1407 as your population grows past 50K civilians. It is disabled by
1409 * Changed "produce" command to accurately print what the true p.e. is.
1410 * Changed "update" command to display if mobility updating is enabled for
1412 * Fixed bug where toggling off the coastwatch flag also turned off
1413 forts firing on hostile ships coming into range.
1414 * Fixed bug where assaulting your own land would violate any treaties
1415 you have where assaults are a violation.
1416 * Fixed bug where all planes (even those without need for a crew, such
1417 as missiles) needed at least 1 military to build.
1418 * Fixed bug where when a ship sinks during the update due to lack of maint,
1419 land units and planes on it were left stranded.
1420 * Fixed bug where when a land unit dies during the update due to lack of
1421 maint, land units and planes on it were left stranded on it.
1422 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
1424 * Fixed bug in "show sector capabilities" not showing products correctly.
1425 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
1427 * Fixed bug in sectors that don't revolt not showing up as lost items.
1428 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
1429 * Fixed bug where MOB_ACCESS was not updating the mobility just before
1431 * Fixed bug in the way treaties are examined and sometimes produce
1433 * Fixed edit to allow creating negative mobility for sectors.
1434 * Fixed setsector to allow creating negative mobility for sectors.
1435 * Fixed bug where when writing out the value of a sector that had
1436 negative mobility and was damaged in combat, mobility was being
1438 * Fixed Taxes.t info page to reflect that captured civvies only pay
1440 * Fixed Technology.t info page to reflect TECH_POP option.
1441 * Fixed navigate.t info page to reflect that only ships in the fleet
1442 in the same sector that are fired upon have damage divided up.
1443 * Made techlists toggle on by default (so things are shown in order of
1444 technological advances.)
1446 Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999
1447 * Added optimization to increasing mobility to check if an object is
1448 already at max mob, just return since it can't be increased.
1449 * Added "-ltermcap" for client libs for hp build (it was already in
1451 * Added clearing of telegram flags after the update so that the next
1452 telegram is flagged as new and not part of the update.
1453 * Fixed Update-sequence.t to reflect MOB_ACCESS.
1454 * Fixed bug where fortification amount was not being limited to
1455 maximum mobility for land units (land_mob_max).
1456 * Fixed bug where land unit fortification strength was being calculated
1457 by using 127 instead of land_mob_max.
1458 * Fixed bug where scrapping land units was creating military.
1459 * Fixed description of sect_mob_neg_factor in econfig file.

1466 * Fixed bug where attacking deity sectors will violate a treaty.
1467 * Fixed newspaper.t information file.
1468 * Fixed potential bug in fixing up timestamp information when restarting a
1469 game with MOB_ACCESS turned on.
1470 * Fixed bug in explore command not setting mobility to correct
1471 value when MOB_ACCESS was enabled.
1472 * Fixed bug in enlist setting mobility incorrectly sometimes.
1473 * Added doc/backup file for deities which recommends how backups and
1474 restores of the data directory should be done.
1476 Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
1477 * Added linux-pthreads target and build for using pthreads under Linux.
1478 * Added NO_FORT_FIRE option which disables the ability of forts to
1480 * Added more error checking and recovery for corrupt data files.
1481 * Changed alphapos target to alpha-pthreads for better clarity.
1482 * Changed fairland to allow 0 sector distance to other islands and
1483 continents (James Risner)
1484 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
1485 match the way ships are described (since this is how they really work.)
1486 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
1487 and "fir" as the number of guns that a land unit fires.
1488 * Cleaned up misc. build warnings.
1489 * Changed artillery damage to be 5 + d6 per gun firing from just d6
1490 per gun firing and updated Damage.t to reflect this change.
1491 * Changed artillery firing ranges to be like ships ranges - divided
1492 by two, and modified them to make more sense.
1493 * Changed artillery units to be "slightly" :) more powerful.
1494 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
1495 * Changed "artillery" unit to tech 35.
1496 * Changed so that guns are no longer required to build units, and
1497 that guns must be loaded onto artillery units for them to fire.
1498 Client developers note: the show command has not changed yet to
1499 remove the 'guns' column (since guns are no longer required) but
1500 will in a future revision (possibly 4.2.4) so "be prepared" for
1501 "show land build" to change. :)
1502 * Fixed landunitgun to handle all the damage calculations like it should.
1503 * Fixed bug sinking planes when the ship they are on sinks.
1504 * Fixed bug destroying planes when the land unit they are on is destroyed.
1505 * Fixed bug where land units could fire support without enough military.
1506 * Fixed bug in abandoning sectors by marching out a land unit where it
1507 would not let you sometimes (uninitialized variable problem.)
1508 * Fixed gets problem in files.c (James Risner)
1509 * Fixed bug in determinig operations range of a ship.
1510 * Fixed bug in building planes where you could manufacture military.
1511 * Fixed warnings in threading package(s).
1512 * Fixed fire.t to reflect new firing changes.
1513 * Fixed lstat.t to reflect new firing changes.
1514 * Fixed sstat.t to reflect the way things really work.
1515 * Fixed Ship-types.t to reflect the way things really work.
1516 * Fixed the way shutdowns work to hopefully better protect data files.
1517 * Fixed bug in attacking when sector mobility is less than 0 and it would
1518 prompt for attacking with a negative amount of military.
1519 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
1520 * Fixed bug in client when it prompts for country name it was putting
1521 an extraneous end of line on the end that needed to be stripped off.
1522 * Fixed problems running on Linux running on an Alpha machine. Thanks
1523 to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
1524 on a machine to work out the bugs. (Note that the only build that
1525 works on Linux/Alpha is the linux-pthreads)
1527 Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
1528 * Added some code optimizations into the update code when building paths.
1529 * Added some new cacheing for building paths to help speed up updates.
1530 * Added so that you can use "name" and "password" with the change command
1531 as well as "country" and "representative".
1532 * Added flag to power command so that if you are a deity and enter
1533 a negative number of countries you want to see, you see the power chart
1534 for that many countries without power numbers on the next line. Only
1535 useful for deities that want to see the chart un-broken up by that line.
1536 * Added new functionality to fortify command. You can now use a negative
1537 fortification value to cause the unit to be fortified and leave at
1538 least that much mobility on the unit. I.E. "fort * -67" will fortify
1539 all units and make sure the mobility of each unit doesn't go below
1540 67. If the mobility is already below that level (or equal) the unit
1542 * Added that the realm command prints "Realm #n is x:x,y:y" after
1543 you set a new realm.
1544 * Added TREATIES option and enabled it by default.
1545 * Added "no depth-charging subs" and "no new land units" treaty
1547 * Added Trannie Carter's basic client fix to use fgets instead of gets.
1548 * Changed market and command to only print the lowest priced lot of
1549 each given commodity by default. If you specify "all" it shows
1550 all lots on the market, and if you specify a specific item, it shows
1551 all lots of that item type.
1552 * Changed start command to only write out sector if it changed.
1553 * Changed stop command to only write out sector if it changed.
1554 * Changed how plane names were changed on server startup if the
1555 PLANENAMES option was enabled.
1556 * Changed move command to use standard askyn function for abandoning
1558 * Changed plane overlight sightings to take stealth into account,
1559 and if the planes managed to evade all flak and interceptors, they
1560 are not marked as "spotted" over enemy sectors.
1561 * Changed all units with the supply flag to have their marching speeds
1562 based on efficiency since that is their purpose. What this means is
1563 that supply units and trains are more effective at 100% than at 10%
1564 (just as fighting units are more effective at 100% than at 10%, but
1565 their effectiveness is determined by how well they fight, not how well
1566 they "run away, run away!" :) )
1567 * Changed so that flash toggle is on by default for POGO at setup
1569 * Changed so that when a sector is taken, all land units owned by the
1570 current owner are treated as planes are during takeovers (i.e. there
1571 is a pretty good chance they are blown up, and if not, they change owner
1572 to the attacker and are beat up pretty good.)
1573 * Fixed treaties to work again.
1574 * Fixed bug in taking over land units not using correct pointer (can
1575 cause a crash or data corruption.)
1576 * Fixed collect command to wipe deliver and distribution information
1578 * Fixed potential bug in bmap not working when destination bmap has
1580 * Fixed bug in shark command not getting right nation structure.
1581 * Fixed bug in server where empty commands (for example, all spaces
1582 or tabs) were being reported as bogus commands. They are now just
1584 * Fixed bug in scrap not dropping land units off of scrapped units carrying
1586 * Fixed bug in news where boarding of land units was reported backwards.
1587 * Fixed bug in calculating new people when growing them during an update.
1588 * Fixed missing -ltermcap in HP/UX build.
1589 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
1590 later and being reset to 0 anyway)
1591 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
1592 since that is what it really is.
1593 * Fixed retreat.t documentation to reflect the "retreat upon failed
1595 * Fixed bug where satellites were not orbiting the world during the
1597 * Fixed bug in torpedos being too smart. They knew how to jump over
1598 land! :) Now the "line_of_sight" routine is used to determine if a
1599 torpedo has a straight path to the destination. If it doesn't, the
1600 torpedo no longer jumps over land, but instead slams into it. This was
1601 an interesting bug because you could torp ships on the other side of
1602 a very skinny island as long as they were in range, even if there was
1603 no sea route possible.
1604 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
1605 units for example) but you still have to pick something to bomb. For
1606 ships it worked ok (just aborted that it couldn't find any more ships)
1607 and this was fixed for land units and planes.
1608 * Fixed server crashing bug when flying a plane and not carrying
1610 * Fixed bug in move losing commodities when it runs out of room in the
1611 destination sector. Goods are now attempted to be returned to the
1612 start sector, and apporpriate steps taken if the start sector is no
1614 * Fixed march to prompt you before you abandon a sector you own by
1615 marching out the last land unit.
1616 * Fixed check functions to only check the relevant portions of the structure
1617 and not the timestamp info that doesn't affect how the object functions.
1618 * Fixed bug in spy command that always told you if a spy unit was in a
1620 * Fixed bug in displaying of land unit missions not showing correct land
1622 * Fixed bug in wire command where new announcements that you read at
1623 the last second don't get wiped out properly.
1624 * Fixed bug where announcement file could be corrupted by very long lines.
1625 * Fixed bug where bmap was not set when player was told what kind of
1626 sector they were attacking (this was an old abusable bug that was
1627 removed long ago to fix the abuse, and it's been fixed in a non-abusable
1629 * Fixed bug where change command would warn you about monetary and
1630 BTU costs, but not prompt you to break out if you didn't want to really
1631 change your country name.
1632 * Fixed bug in sub-launched nukes that are intercepted being reported in
1633 the news incorrectly.
1634 * Fixed bug in load where you could abandon a sector and not know it by
1635 loading your last civilians or military onto a ship.
1636 * Fixed potential memory leak in autonav code.
1637 * Fixed potential bug where you could possibly determine if a sector is
1638 owned or not using one way plane missions.
1639 * Fixed Damage.t info page to properly show damages for planes and
1641 * Fixed deliver.t to include syntax for command.
1642 * Fixed country.t to include syntax for command.
1643 * Fixed bug where ships on orders were not adding radar information to
1644 the bmap during an update.
1645 * Fixed bug where ships on sail were not adding radar information to
1646 the bmap during an update.
1647 * Fixed bestownedpath code to use the bmap properly. Note this is a very
1648 important bug fix. When navigating a ship, players are no longer given
1649 free information that they would not normally know. For example, if you
1650 try sailing your ship off into uncharted areas of your bmap, the bestpath
1651 code will only use as much information as you have on-hand (i.e. your
1652 bmap) to plan out your path for you. If you have no information on an
1653 area, it just keeps forging on, until bumping into something. Of course,
1654 after the initial exploration through an area, the bmap will be set and
1655 used for all future sailings through that area. Harbors and bridges
1656 are still checked for construction worthiness if you know where they
1657 are (i.e. they are on your bmap.) (Overall, what happened before
1658 was that the bestpath code would route your ship around islands that
1659 you didn't even know were there, and you could use various commands
1660 to see how that ship was going to sail during the update and thus you
1661 gained information that you wouldn't normally know.)
1662 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
1663 and "BestAirPath" to use it properly. It is also good to note that
1664 bestownedpath is used to determine paths for ships and for planes,
1665 and that best_path (which uses the A* algorithm) is used for all land
1666 based paths, and that the two are never interchanged.
1667 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
1668 and RECON was never used before.)
1669 * Removed extraneous "resnoise" and "resbenefit" functions and combined
1670 the two for setresource and setsector commands.
1672 Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998
1673 * Fixed problem with global/plane.c not defining last structure element
1674 properly, and thus causing crashes when accessing certain plane
1675 routines. This happened during the move to make the PLANENAMES option
1676 run-time configurable.
1678 Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
1679 * Bumped rev to 4.2.0 since this is a major release (the server is now
1680 run-time configurable for just about everything and is released under
1682 * Put in official licensing information.
1683 * Re-arranged and commented the econfig (Empire Configuration) file. The
1684 auto-generated "data/econfig" file is now pumped out chock full of
1685 comments (which may or may not be useful.) Since the server is
1686 pretty much fully run-time configurable (MAXNOC is not, but it gets
1687 a default of 99 anyway) deities will probably be spending more time
1689 * Added server support for building under NT, including mods from
1690 Doug Hay and Steve McClure to get the server building and running
1691 under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
1693 * Added Doug Hay's ntthread.c implementation for NT threading.
1694 * Added max pop column to "show sector stats" output.
1695 * Added lboard command for boarding land units from sectors. Only raw
1696 mil can board land units, and only mil and land units aboard the unit
1697 being boarded fight back.
1698 * Added GODNEWS option. When enabled, the deity giving people stuff
1699 is shown in the news.
1700 * Added bridge tower sector ('@')
1701 * Added BRIDGETOWERS option. When enabled you can build bridge towers
1702 from a bridge span. You can then build bridge spans from the tower.
1703 If the tower is destroyed ( <20% eff) bridges connected fall unless
1704 supported on the other side. You can only build bridge towers in open
1705 water not adjacent to land and other towers. Expensive.
1706 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
1707 it is deity creatable only (can't redesignate unless you wasteland it
1709 * Changed "info all" to no longer use printdir, instead it just uses the "all"
1710 info page which contains this information.
1711 * Changed so you can now load up to 2 spy units onto non-land unit carrying
1712 submarines if the LANDSPIES option is enabled. Useful for sneaking up
1713 to shore and spying on your neighbors.
1714 * Changed so spies unloaded from ships are not given as gifts, they are just
1716 * Changed build command to handle building towers ("build t")
1717 * Changed show command to show tower stats ("show t b")
1718 * Changed reject so you can now reject things from any country except
1719 deity countries (this now includes sanctuary countries and visitor
1720 countries you don't want to deal with)
1721 * Changed ndump to dump nuclear stockpile ID as well.
1722 * Changed flash so that if someone allied to you is either not logged on or
1723 not accepting flashes, you are notified. This is info you could gain
1724 otherwise since you can see other countries that are allied to you via
1726 * Fixed bug in news command when HIDDEN mods are enabled.
1727 * Fixed distribute command to only write out to the database if we
1728 actually changed the sector (i.e. if we really moved the dist
1729 center, we write. Otherwise, it makes no point.)
1730 * Fixed threshold command to only write out to the database if
1731 we actually changed the sector (i.e. if we really changed the
1732 threshold, we write. Otherwise, it makes no point.)
1733 * Fixed - population growth and truncation in "Update-sequence.t" info
1735 * Fixed the way fortify takes mobility away from a land unit if
1736 engineers are present.
1737 * Fixed bug in buying commodities at the last minute not resetting the
1738 time correctly in all situations.
1739 * Fixed bug in building nukes where it would always ask if you tried
1740 building more than one at a time.
1741 * Fixed bug where if you put (either by building or by transporting)
1742 more than 127 of one type of nuke in a sector, they all got lost. A
1743 negative wrapover sort of thing.
1744 * Fixed ndump to print # of stockpiles dumped.
1745 * Fixed ndump.t to reflect changes
1746 * Fixed bug in build command that didn't account for EOL characters.
1747 * Fixed bug where you could use planes to drop conquered populace
1748 * Fixed bug in distribute command in how it checked for current distribution
1750 * Fixed pr_flash and pr_inform to no longer send messages if the player
1751 is still in the process of logging in (i.e. not in the PLAYING state)
1752 * Fixed report command output for deities.
1753 * Fixed bug in nuclear damage either taking out submarines when it
1754 shouldn't, or not taking them out when it should.
1755 * Fixed bug in loading units that are carrying units onto other units
1756 (note that it doesn't happen since only HEAVY units can carry other
1757 units and that check works, but that might change some day, and we
1758 don't want units carrying units to be carried by other units, etc. :) )
1759 * Fixed info pages to reflect new sector types.
1760 * Fixed info pages to reflect new spy unit capabilities.
1761 * Fixed show commands to only show trade ships if the TRADESHIPS option
1763 * Fixed build command to only allow building of trade ships if the
1764 TRADESHIPS options is enabled.
1765 * Fixed up some definitions located in many places used for checking
1766 sectors for navigation rights.
1767 * Fixed power.t to correctly describe NEW_POWER formula.
1768 * Made HIDDEN option run time configurable.
1769 * Made LOSE_CONTACT option run time configurable.
1770 * Made ORBIT option run time configurable.
1771 * Made SAIL option run time configurable.
1772 * Made MOB_ACCESS option run time configurable.
1773 * Made FALLOUT option run time configurable.
1774 * Made SLOW_WAR option run time configurable.
1775 * Made SNEAK_ATTACK option run time configurable.
1776 * Made WORLD_X and WORLD_Y run time configurable.
1777 * Made MARKET option run time configurable.
1778 * Made LOANS option run time configurable.
1779 * Made BIG_CITY option run time configurable.
1780 * Made TRADESHIPS option run time configurable.
1781 * Made SHIPNAMES option run time configurable.
1782 * Made DEMANDUPDATE option run time configurable.
1783 * Made UPDATESCHED option run time configurable.
1784 * Made LANDSPIES option run time configurable.
1785 * Made NONUKES option run time configurable.
1786 * Made PLANENAMES option run time configurable.
1787 * Removed SMALL_SERVER stuff (unused baggage)
1788 * Removed trading post sector ('v')
1790 Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
1791 * Fixed bug in aircombat where planes in flight could intercept air
1792 defense planes and take no damage (i.e. they got to fight twice,
1794 * Fixed bug in freeing memory after performing missions that could crash
1795 the server (it mainly happened after an interdiction mission using
1796 planes and escorts, where some escorts came from airports that didn't have
1797 bombers going up. Freeing the leftover escorts was crashing the server.)
1798 * Fixed bug where you could load non-existant units if you were allied
1800 * Fixed bug where you could pin-bomb a plane with itself.
1801 * Fixed bug where satellites over a bridge may get killed if the bridge
1803 * Fixed bug where land units on a ship in the same sector as a bridge
1804 that is splashed may get sunk.
1805 * Fixed bug where planes on a ship in the same sector as a bridge
1806 that is splashed may get sunk.
1807 * Fixed doconfig with correct empire site text.
1808 * Fixed major problem with abms not firing, and sometimes crashing
1810 * Fixed bug in land units counting up loaded units wrong.
1811 * Fixed doconfig makefile to have doconfig.c as a dependency.
1812 * Fixed bug in resetting commodities (the comm_uid was not being
1814 * Fixed bug in repaying loans not working correctly (the l_uid was not
1815 being properly set.)
1816 * Fixed bug in buying items from the trading block not allowing you
1817 to due to a perceived change in item status.
1818 * Fixed bug in mfir.c where a bogus input to a target could crash
1820 * Fixed bug that after you read telegrams new telegrams may not send
1821 an inform message (the old telegram flags were not cleared.)
1822 * Fixed bug where fort support distance calculations are calculated
1823 twice instead of just once. This bug caused a lower percentage
1824 of support fire than designed.
1825 * Fixed bomb.t to reflect land unit changes.
1826 * Put in some integrity checking for planes returing from bombing runs.
1827 * Added ability to edit land unit that a land unit is loaded on in
1829 * Consolidated bridgefall code into "knockdown" function (this code
1830 existed in at least 3 places, and was different in all of them.)
1831 * Subs returning fire are no longer reported in the news.
1832 * Visitor countries can now use the 'motd' command.
1833 * When trying to use a visitor country, if it is in use, you are not told
1834 by whom, just that it is in use.
1835 * Optimized (slightly) support fire from forts not getting supply and
1836 shells if not needed (out of range)
1837 * Updated Education.t
1838 * Modified (increased) chances of hitting mines slightly.
1839 * Removed unused variables from shp_check_mines.
1841 Changes to Empire 4.0.17 - Fri Jul 31 06:12:21 PDT 1998
1842 * Added ability in edit to change coastal flag for sectors.
1843 * Added ability in edit to edit plague values for ships.
1844 * Added ability for "spy" to report all units/planes not owned by you
1845 that exist in the sector you are spying from.
1846 * Modified naval planes and anti-sub planes.
1847 * Changed so that missiles and bombs that miss their targets cause
1848 collateral damage in the target sector (they have to land somewhere!)
1849 * Changed llook so that non-spy units are required to have at least 1
1850 military personnel on board to see anything.
1851 * Fixed "llookout.t" to reflect change for military requirement.
1854 * Added "lmine" flag for deities to see what sectors have mines in them
1855 (works for sea and land mines, used "lmine" to distinguish it from "min"
1856 which determines mineral (iron) content of a sector.)
1857 * No longer able to pin bomb land units on a ship.
1858 * Land units are required to have at least one military loaded to perform
1860 * Firing land units are required to have at least on military loaded to
1861 be able to fire (or return fire.)
1862 * Spies are not always seen when being pinbombed. You have to look very
1863 carefully for them (as you usually would.)
1864 * Fixed typo in "Spies.t"
1865 * Added new info about spy ability to spy.t.
1866 * Updated tax information in Innards.t and Update-sequence.t
1867 * Fixed typo in fire.t information about units firing on ships.
1868 * Loading military onto land units now resets fortification. (You gotta
1869 re-fortify the new guys.)
1870 * Fixed bug where planes that were mine capable could not drop mines if
1871 they were not cargo capable.
1872 * Fixed bug in potentially crashing in update code for nations tech/research.
1873 * Fixed bug in execute putting you into execute mode incorrectly.
1874 * Fixed bug in board not allowing land units to board from 0 mobility
1876 * Fixed bug where interdicted land units that were missed displayed
1877 a "SPLASH! Bombs miss your ships" message.
1878 * Fixed bug in minesweeping sectors where, even with mobility or
1879 having the sweep ability, ships would get hit by mines for doing
1881 * Fixed bug in count_land_planes always writing out land units unnecessarily.
1882 * Fixed bug in count_planes always writing out ships unnecessarily.
1883 * Fixed bug in lnd_count_units always writing out land units unnecessarily.
1884 * Fixed bug in count_units always writing out ships unnecessarily.
1885 * Fixed bug in llook that reported units on ships.
1886 * Fixed bug in llook that reported satellites launched over the unit.
1887 * Fixed bug in llook that always reported spies (it should be a 10-100%
1889 * Fixed bug in anti possibly not saving lost items correctly.
1890 * Fixed bug in planes getting extended range when on missions and the
1891 op center is not where the plane is located.
1892 * Fixed bug in land unit defensive strength not being based on the eff of
1893 the unit when calculating odds of a battle.
1894 * Fixed bug in board not reporting consistant information.
1895 * Fixed bug in the way land unit casualties were being taken.
1896 * Fixed bug where land units on ships could return fire.
1897 * Fixed bug where land units on other land units could return fire.
1898 * Fixed bug where land units on other land units could fire.
1899 * Fixed bug in attacks/assaults/boardings spreading plague incorrectly.
1900 * Fixed bug in updating plague for ships.
1901 * Fixed bug in updating plague for land units.
1902 * Fixed bug in updating plague for attacking/defending land units.
1903 * Fixed bug where you couldn't pin-bomb land units that were < 20% eff.
1904 * Fixed bug which revealed the owner of torping subs when on a mission.
1906 Changes to Empire 4.0.16 - Fri Jun 12 08:52:06 EDT 1998
1907 * Added patches sent in by Steve McClure, Sverker Wiberg and Curtis
1908 Larsen. They are described with other changes below.
1909 * Fixed bugs in the following commands that allowed two cooperating
1910 countries to create infinite numbers of any commodity and/or cash
1911 at any time (race conditions in the server): build, board, deliver,
1912 designate, distribute, explore, fuel, improve, load, ltend, mobquota,
1913 move, name, order, reset, sail, sell, set, tend, territory, test,
1914 threshold, torpedo, transport, unload
1915 * Fixed bug in board command giving out too much information about a
1916 non-owned sector when it shouldn't be.
1917 * Fixed bug in board command when firing on a sector in defense before
1919 * Fixed bug in rangeedit allowing plane(s) to possibly be stored wrong.
1920 * Fixed bug in launch allowing plane to possibly be stored wrong after
1922 * Fixed bug in lrangeedit allowing land unit(s) to possibly be stored wrong.
1923 * Fixed bug in morale allowing land unit(s) to possibly be stored wrong.
1924 * Fixed bug in arm/disarm allowing a plane to possibly be stored wrong.
1925 * Fixed bug in loan sometimes not writing database correctly.
1926 * Fixed bug in collect.
1927 * Fixed bug in dropping mines from land units.
1928 * Fixed crashing bug in sector_strength routine when oceans take
1930 * Fixed bug in transport possibly decrementing too much mobility when
1932 * Fixed some little warning type messages building with gcc -Wall.
1933 * Fixed problem compiling lwp threads with glibc6 under Linux.
1934 * Changed flash so that players can always flash deities.
1935 * Changed players command to always show deities and visitor countries
1936 that are logged on, and only show allied countries for normal player
1938 * Fixed bug in anti command not stopping sectors when they revolt.
1939 * Fixed bug in set_coastal function not counting bridge spans as

2023 problems since supply is still somewhat broken somewhere)
2024 * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
2025 submitted patches, which collectively included cleaning up most
2026 of the server prototypes and bogus declarations. Many thanks.

2052 * Fixed bug in parse.c that was screwing up double quotes in conditional
2054 * Military in a sector now only produce up to maxpop, just like civvies
2055 and uw's. No more stuffing 6K mil into a mountain to max it out. You
2056 can still hold more mil there over the updates, but the extras just
2057 won't produce anymore.
2058 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
2060 * Fixed bug in day of week calculation for server up time in common/keyword.c

2127 * Fixed "sell.t" info page.
2128 * Fixed bug in "buy" where not entering the price correctly could cause
2130 * Fixed "sell" so that at least 1 mobility is required to sell goods. Keeps
2131 the midnight "raid and sell" abuse down. :)
2132 * Fixed "show plane cap" to move the last column over 1 more where it should
2134 * Fixed timestamps to be updated for units/planes on ships/units that move,
2135 since those units/planes move too.
2137 Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
2138 * Fixed bug in nstr_exec that was wiping out the previous conditional.
2139 This was major because it affected timestamp values which are more
2141 * Fixed bug in sdump.c for typo in reporting the trade ships origin.
2143 Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
2144 * Fixed bug in aircombat.c when calculating the air combat odds. Negative
2145 numbers were screwing things up good...
2146 * Fort sector's coordinates are no longer printed when auto-firing at
2148 * Subs can now surface and fire deck guns (again) They can also be
2149 hit by return fire when doing so.

2151 negative numbers don't keep going further negative.

2153 * Trading posts are no longer required to sell goods from. You can sell

2157 * Loading land units now prints out what was loaded onto each unit,
2158 just as loading ships do.

2163 48 hours. This determines how long lost items stay in the lost items
2165 * Fixed land unit names to be more consistent.
2166 * Fixed mission.t info page.
2167 * Fixed bug in that if mission_mob_cost was set to 0, even negative
2168 mob units should be able to be put on missions.
2169 * Removed restriction on things needing to be at least 60% to be put
2170 on a mission. Note that while you can put them on missions at < 60%
2171 now, when trying to do the mission, it still checks the eff. This
2172 is to help in automatic setup (build, put on mission, forget) instead
2173 of having to come back repeatedly.
2174 * Spies caught in Neutral or Friendly countries cause the Neutral or
2175 Friendly country to go Hostile towards the owner of the spy.
2176 * Tweaked ammunition numbers for artillery units.
2177 * No more automatic declarations of War should be made. You will go
2178 hostile, but since going to war doesn't increase your countries
2179 defenses, and is purely political, it is left to the player to go
2181 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
2182 * Fixed bug in "lmine" that was crashing the server if the land unit was
2184 * Fixed buy so that if you specify a product, you can only bid on that

2190 * Fixed nstr_comp to deal with values > 16 bits coming in from
2191 client for comparisons.
2192 * Changed last minute market/trade timers to increment 5 minutes. 2 minutes
2194 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
2195 * Commented out the logging of the market checking in server/marketup.c,
2196 lib/commands/buy.c and lib/commands/trad.c It was generating lots of
2197 pretty much useless data that made parsing the server.log file more
2198 more difficult than it needed to be.
2199 * Fixed crashing bug in ldump.
2200 * sdump, ldump, ndump, pdump and dump now print out the current
2201 timestamp on the "DUMP XXX" line.
2202 * Fixed denial of service bug in lib/player/accept.c in
2203 player_find_other function.
2204 * Fixed bug in shark reporting incorrect buyer of the loan.
2205 * Fixed bug in sdump.c (case 0 should have been case 10)
2206 * ldump and sdump now always print the fuel column if asked for,
2207 even if opt_FUEL is turned off. In the case that it is turned
2208 off, the fuel is listed as 0.
2209 * Added "timestamp" field, which is updated every time an item is
2211 * Fixed up the Clients.t info page.
2212 * sdump now prints trade ship building origin.
2213 * sdump now always prints name even if SHIPNAMES isn't defined. If
2214 it is not defined, then the name is empty.
2215 * Added "timestamp" to info/Concepts/Selector.t
2216 * Added some more relevant info to info/Server/Empire4.t
2217 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
2218 is no longer torn down when a sector is re-designated.
2219 * Fixed sell.t to more accurately reflect the time-delay market.
2220 * Fixed read.t and wire.t to reference accept and reject.
2221 * Fixed reject.t not referencing accept command.
2222 * Fixed collect.t to more accurately reflect what goes on when collecting
2224 * Fixed financial.t to reflect defaulted loans.
2225 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
2227 * Fixed "census.t" (had incorrect reference to "info syntax" instead
2230 Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
2231 * Increased damage from depthcharges because on increased damage from
2232 torpedos. Sub frange decreased to be more balanced with destroyer frange.
2233 * Intelligence reports (spy) on units will now report the estimated number
2235 * Fixed equation for ship visibility so it will drop as tech increases.
2236 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
2237 land units, planes, and nukes.
2238 * If fields are provided, dump will only supply those fields requested.
2239 * Decreased speed of subs.
2240 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
2241 required for infrastructure improvements.
2242 * Units that lose an assault or a boarding attempt from a ship will no
2243 longer swim back to the ship they came from.
2244 * Units that take extra casualties will no longer lose all their mil at
2246 * Infrastucture is retained when redesignating a sector.
2247 * Dieing spies will no longer crash the server.
2248 * Units, planes, and ships must have mobility to perform missions.
2249 * Units on ship being scrapped are transferred to harbor.
2250 * Food is no longer autoloaded onto units when they are built.
2251 * Fixed show plane stat to show correct range.
2252 * Infantries now take damage at same rate as casualties.
2253 * Fixed bug with hap_fact. Having more happiness now helps with fighting
2255 * Fixed anti to write back target country so che will continue to fight
2257 * Fixed llookout to show correct estimate on number of mil on unit.
2258 * Added buildable architecture "hp". This type will build the server on
2259 a HP/UX machine using the standard compiler instead of gcc.
2261 Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
2262 * Fixed bug in update/distribute.c where pathcost was not being called with
2263 the MOB_ROAD argument (and thus distribution costs could be GREATLY
2264 affected.) - Thanks Ice!
2266 Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996
2267 * Fixed Solaris port using gcc.

2279 * Put in change in lnd_mobcost in lndsub.c
2280 * Put in new nuke costs in nuke.c
2281 * Put in fix so that total work can only be done by the max pop. No more extra
2282 civvies tossed in will do it anymore in human.c.
2283 * Put in fix for src/util/Makefile - beefed it up.
2284 * Put in fix to show where your ship is when it gets shelled in mfir.c.

2303 * Fixed attack value in attack_val in lndsub.c
2304 * Fixed lload in commands/load.c
2305 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
2306 always fight until dead or retreating. 0 makes them get stuck.
2307 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
2308 else for that matter.)
2309 * Fixed llook in commands/look.c
2310 * Fixed che bug in subs/nstr.c
2311 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
2312 of people would starve.)
2313 * Fixed update/human.c - feed_people rounding problems (I hope.)
2314 * Fixed morale problem in update/land.c
2315 * Fixed count_bodies in attsub.c
2316 * Fixed lnd_mobcost.
2317 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.

2319 * Fixed bug in buy.c.
2320 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
2321 infrastructure. When off, the defensive infrastructure is the same
2322 as the sector efficiency, and you can't improve it. This is OFF by
2326 * Land units are now built with a default reaction radius of 0.
2327 * Changed name of lt artilleries to "lat" from "lart" so you can now build
2329 * Lowered the speed and firing range of pt boats.
2330 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
2332 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
2333 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
2334 1.5 * ETU_RATE for ships.)
2335 * Conquered civvies only pay 1/4 taxes.
2336 * Railways don't get torn down when you rebuild sectors anymore (but roads
2337 and defenses do (if enabled.)
2339 Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
2340 * Added "extern double tradetax" to check_trade in trad.c
2341 * Improved description of data directory in build.conf
2342 * Fixed bug in attacking land units that retreat so they now get
2343 charged mobility for attacking.
2344 * Fixed dump to report road, rail and defense of a sector at the end.
2345 * Fixed doconfig bug in not checking the right directory to see if the
2346 "data" directory existed or not before trying to create it.
2347 * "change" now works for sanctuary countries.
2348 * Fixed the description of "sinfrastructure".
2349 * Added more info to "Infrastructure".
2350 * Units/planes are no longer reduced to 75% when bought from the trading
2352 * Supply units were slowed down to the speed of infantry units.
2353 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
2354 * Bars interest is up to $250 per 1K again.
2355 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
2356 * Fixed various info pages.
2357 * Fixed bug in people not getting truncated when broke (this was thought
2358 to be fixed, but wasn't. Now it is, dammit!)
2359 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
2360 * Market/trade taxes and trade ship payoff figures were added to version.
2361 * "cede" has been removed as a default command.
2362 * Makefile rule was fixed for depend build.
2363 * Fixed bug in mapdist not taking world edges into account nicely enough.
2364 * Added a "scuttle" order for autoscuttling trade ships. Makes using them
2365 easier. Cleaned up scuttle code while in there.
2366 * Fixed bug with scuttling a ship with units on it not scuttling the units
2369 Changes to Empire 4.0.0 - Wed Aug 21 1996
2370 * Initial Wolfpack release - Long live the Wolfpack!!!!
2371 * Cleaned up the build environment. Now all that is needed is to edit the
2372 build.conf file, answer the questions there and type "make <arch>" to
2373 build for a specific architecture. Thus, no more reliance on gnumake
2374 or special shell scripts.
2375 * We are now shipping the pre-built info pages with the server for those who
2376 Don't want to build them. You can also still just type "make" and have
2377 the info pages build, but it doesn't completely work (i.e. rebuild new
2378 Subjects) if you don't have perl5 installed.
2379 * Put in the "help" command that does the same thing as "info".
2380 * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or
2381 wish to support it. 2) We envision a better scheme for doing similar
2382 things will come along.
2383 * Put in MOB_ACCESS - This allows real-time updating of mobility.
2384 * Put in MARKET - This is the time-based market (yes, still teleports,
2385 but it's not as bad as it was.)
2386 * Lots of the documenation has been updated, but there is more to do.
2387 * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are
2388 enabled, you don't need any of that type of material to build things.
2389 If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
2390 lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need
2391 any materials to build a bridge.
2392 * There is no mobility cost for assigning missions. But, there is also
2393 no longer any benefit for being on a mission either.
2394 * Damage is the same for all commodities (people too.) This means you
2395 can deity shell/bomb sectors again.
2396 * Units are now dependant on tech. What this means is that their statistics
2397 now increase with tech. In addition, there is only 1 type of each basic
2398 unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
2399 This reflects the idea that as you learn more, you learn how to not only
2400 build better units, but you learn to build units better. :) This also
2401 opens the door for a "lupgrade" command along the same lines as the
2402 "upgrade" command for ships.
2403 * Units now have a minimum mob cost for attacking a sector. Marching
2404 mob costs have not changed.
2405 * Starting units have been removed. This means that at the beginning, people
2406 may live a little longer since their neighbor can't come visiting quite
2408 * Shells are no longer required to build units.
2409 * Mil are no longer required to build units.
2410 * Mil are no longer an intrinsic part of a unit. They are now a loadable
2411 commodity. The way a unit's defense/att bonuses work now are
2412 attack = (att * mil * eff)
2413 defense = (def * mil * eff)
2414 In addition, when a unit takes damage, both the eff and the mil go
2415 down. You can quickly toss in new hacks, but you need to wait to repair
2416 the unit at the update. Thus, you can now look at unit's efficiency
2418 * You need at least 1 mil on a unit to march it (spies are the exception.)
2419 * Units always react if in range and they have the mobility, no matter
2420 what their efficency.
2421 * Units may now march anywhere - in your own sectors, deity owned sectors
2422 or allied sectors, with 1 exception, spies. Also, your units can get
2423 trapped if your ally declares non-alliance with you while your units
2424 are still in his country.)
2425 * Units always march at their speed, efficiency doesn't matter.
2426 * LANDSPIES was added - This creates land unit based spies. Spies may march
2427 anywhere, with a chance of getting caught (except in allied territory.)
2428 See "info Spies" for more info on them.
2429 * Planes may now be based out of allied airports. Landing planes on
2430 ships/sectors you do not own no longer changes thier owner. You can only
2431 land on owned/allied sectors/ships, and you may only
2432 fly/bomb/para/recon/drop from owned/allied sectors. So, if a country
2433 you are allied with goes hostile at you, your planes are now stuck there.
2434 Note that if you are using an allied airport, their commodities get
2435 sucked up, not yours (obviously.)
2436 * Planes are now tech-based. Their statistics increase as their tech
2437 increases. Deleted extraneous planes.
2438 * There is a new toggle, "techlists", which allows you to see what you
2439 can build/stats/capabilities sorted by tech instead of groupings.
2440 * Ships are now tech-based. Their statistics increase as their tech
2441 increases. Deleted extraneous ships.
2442 * Che can now be lessened by making happiness. If you have more happiness
2443 than your conquered populace, they don't fight as hard or recruit as
2444 much. If you have less than them, they fight harder and recruit more.
2445 It's not much though - it ranges from 2.0 in your favor to only 0.8
2446 against you (whereas it was always 1.0 before.) So, it definitely
2447 favors the attackers to make lots of happy now.
2448 * Bridgeheads can only be built on coasts.
2449 * Players command was fixed so you only see allies, and don't get
2450 approx #'s of players anymore.
2451 * POSIX threads support has been added.
2452 * The attack bmap bug has been fixed.
2453 * BTUs regenerate 3 times faster now.
2454 * GRAB_THINGS is off by default.
2455 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
2456 as a default (you couldn't make wasteland before with FALLOUT, now
2458 * You can now deliver military and civilians.
2459 * Added SHIP_DECAY option - off by default (turns off ships decaying out
2460 at sea if not enough mil.)
2461 * The reverting owner bug has been fixed in territory, thresh, dist
2462 and deliver. There are probably more, and when found, will be fixed.
2463 * The "sectors don't starve when stopped or broke" bug has been fixed.
2464 * The "people never get truncated" bug has been fixed.
2465 * Added infrastructure to sectors. What this means is that a sector
2466 can now have it's mobility improved by building both roads and
2467 railways. It also means that a sectors defense is now based on the
2468 defensive infrastructure you build into the sector (no more intrinsic
2469 better defenses based on the sector, you determine which sectors are
2470 defended heavily, and which aren't.)
2471 * The defensive value of a sector no longer relies on the efficiency of
2472 the sector. Instead, it relies on the defensive efficiency of the sector.
2473 Thus, the "production" and "defensive" aspects of sectors have been
2475 * "show sect stats" now shows the maximum defensive value for sectors.
2476 * Changed sector structure to take floats for off/def values so we can use
2477 a base of 1 instead of 2.
2478 * Added "improve" and "sinfrastructure" to support the infrastructure
2480 * Added L_TRAIN units which can only travel along railways. Very fast on
2481 efficient railways, slow on non-efficient ones.
2482 * Added the ability for units to carry other units.
2483 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
2484 * Forts only cost $500 to build and 100 hcms now (since they don't get any
2485 better defenses automagically.)
2486 * Modified "show sect build" to show the costs for building up the
2487 infrastructure of a sector.
2488 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
2489 spyplanes too) to show the new infrastructure stuff, rounded of course.
2490 * Added Drake's info->html scripts, with some modifications, so you can
2491 now type "make html" and have your info pages built as html files too.
2492 This adds a new directory, "info.html", to the build tree.
2493 * Modified upgrade so that planes and land units may now be upgraded.
2494 * Added pstat command to list the statistics of your planes.
2495 * Added lstat command to list the statistics of your land units.
2496 * Added sstat command to list the statistics of your ships.
2497 * Added nmap command to show a map of your sectors after their new
2498 designations have taken place.
