 * Fixed multiple cases where return value of getstarg() was
   used without being checked which crashed the server.
 * Used stdarg.h instead of varargs.h.

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

Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001

 * Accuracy calculation in land unit support was backwards.
 * Corrected formula for likelihood of plague in info Plague.
 * Fixed files to correctly size map and bmap files from econfig file.
 * No longer allowed to add country 0.  It corrupts deity country.

Changes to Empire 4.2.8 - Mon Oct  9 17:35:35 MDT 2000
 * Fixed range in radar.t and Sector-types.t.  Maximum range at infinite
   tech is 16.

Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
 * Added new NF_SACKED flag to indicate when a country has had it's
   capital sacked.  This flag is only cleared when the country actively
   redesignates it's capital using the "capital" command, and changed
   capital.t to reflect this (no more re-sacking after an update if the
   country doesn't reset and repeating until they are out of cash.)
 * Added land unit to edit command for planes.
 * Added nuketype to edit command for planes.
 * Changed so that if the leader of a group of units is a train, the
   railways are used for bestpath instead of roadways.
 * Changed mission command to also print reaction radius of reserve
   missions when set for land units.
 * Changed Flak.t to reflect guns having to be loaded onto a land unit
   for flak to fire.
 * Changed so that visitor countries cannot change their name or password.
 * Changed so that you cannot upgrade deity planes, ships or units.
 * Changed so that you know where missions are flown from.
 * Changed so that the airport owner you fly a mission from is informed.
 * Changed so that preperations for takeoff are reported to the owner of
   the sector, ship or unit a plane is taking off from if it is not owned
   by the owner of the plane.
 * Changed so that when a sector reverts during a guerrilla revolt, the
   mobility is not reset.  When MOB_ACCESS is not enabled, this used to mean
   you would always get at least an updates worth of mobility.  With
   MOB_ACCESS, sectors that reverted during the update were useless, since you
   got no mobility for a long time.  This fixes that problem, and makes che
   more useful as well.
 * Changed so that air defense missions don't always send up every plane in the
   area, but instead always send up at most two times the number of incoming
   planes (for each interdicting country.) This helps to stop 1 plane from
   stripping the mobility from 25 air defense planes all at once, but doesn't
   limit it to n+1 as there is for regular interception.
 * Clarified deity reversion of sectors in Sector-ownership.t
 * Clarified production efficiency and added pointer to "show sector cap"
   in Product.t
 * Clarified nuketype selector for planes in Selector.t
 * Clarified that fortifying units does not affect mission status in info
   pages for mission and fortify.
 * Clarified fuel syntax upon error in fuel command in empmod.c.
 * Cleaned up comments causing minor complaints in some builds.
 * Fixed bug in loans where you could collect on proposed loans.
 * Fixed production command to be more accurate (though it *still* has some
   rounding errors, it's better.)
 * Fixed potential memory leak in air defense missions.
 * Fixed bug where you couldn't pinbomb some commodities if other commodities
   didn't already exist in the sector.
 * Fixed bug where you couldn't build 0 crew planes without military in the
   sector.  (This is different from needing at least 1 military to build all
   planes that need a crew which introduced another related bug earlier.)
 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
   messages to be displayed for deity owned planes.
 * Fixed bug where land units on ships in a sector taken over were blown
   up or captured.
 * Fixed bug where planes on ships in a sector taken over were blown up
   or captured.
 * Fixed bug in sdump printing origx and origy in deity coordinates.
 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
   optional arguments.
 * Fixed bug in launch showing wrong satellite target (showed asat instead
   of the target satellite.)
 * Fixed bug where you could gain information not normally available using
   the "fire" command to determine sector type information.
 * Fixed bug in market/trade creating extra money when loans are taken out.
 * Fixed problem with land units not being reported sunk after being sunk
   on a ship that was nuked or wastelanded in a sector.
 * Fixed problem with Spies.t using "llook" instead of "llookout".
 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
   on some Linux boxes.
 * Fixed problem with plague infection being way too high in cities when
   the BIG_CITY option is enabled.
 * Fixed bug in edit command getting confused with arguments.
 * Fixed bug in ask_move_in_off asking you to move in a negative number of
   troops (hey, it could happen. :) )
 * Fixed bug in add command not keeping flags or relations initially correct.
 * Fixed bug in torpedo command sometimes telling victim about torpedo
   sightings even when way out of range.
 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
   as not formatting them properly when reporting them.
 * Fixed bug in satellite with noisy transmission causing a potential
   crash of the server with non-100% efficient satellites.
 * Fixed potential crashing of the server during satellite display when not
   calculating distances to ships and units correctly.
 * Fixed bug where planes in non-allied sectors, ships and units could be
   used on missions.
 * Fixed bug where planes on the trading block could be used on missions.
 * Fixed bug where planes and units that get traded don't have mobility set
   correctly when using MOB_ACCESS option.
 * Fixed bug which made security units virtually useless.
 * Fixed access times and mobility not being set right when building planes,
   ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
 * Fixed minor formatting problem with launch of satellites.
 * Fixed minor formatting problem with planes with greater than 999 tech.
 * Fixed minor formatting problem with ships with greater than 999 tech.
 * Fixed problem with "llook" showing up in TOP info file.
 * Fixed problem with lwp Makefile choking on NT builds with clean target.
 * General cleanup of potentially ambiguous statements.

Changes to Empire 4.2.6 - Fri Jun  4 05:55:20 PDT 1999
 * Added "TECH_POP" as an option where technology costs more to make
   as your population grows past 50K civilians.  It is disabled by
   default.
 * Changed "produce" command to accurately print what the true p.e. is.
 * Changed "update" command to display if mobility updating is enabled for
   MOB_ACCESS option.
 * Fixed bug where toggling off the coastwatch flag also turned off
   forts firing on hostile ships coming into range.
 * Fixed bug where assaulting your own land would violate any treaties
   you have where assaults are a violation.
 * Fixed bug where all planes (even those without need for a crew, such
   as missiles) needed at least 1 military to build.
 * Fixed bug where when a ship sinks during the update due to lack of maint,
   land units and planes on it were left stranded.
 * Fixed bug where when a land unit dies during the update due to lack of
   maint, land units and planes on it were left stranded on it.
 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
   while arming.
 * Fixed bug in "show sector capabilities" not showing products correctly.
 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
   towers".
 * Fixed bug in sectors that don't revolt not showing up as lost items.
 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
 * Fixed bug where MOB_ACCESS was not updating the mobility just before
   the update. 
 * Fixed bug in the way treaties are examined and sometimes produce
   wrong results.
 * Fixed edit to allow creating negative mobility for sectors.
 * Fixed setsector to allow creating negative mobility for sectors.
 * Fixed bug where when writing out the value of a sector that had
   negative mobility and was damaged in combat, mobility was being
   set back to 0.
 * Fixed Taxes.t info page to reflect that captured civvies only pay
   1/4 taxes.
 * Fixed Technology.t info page to reflect TECH_POP option.
 * Fixed navigate.t info page to reflect that only ships in the fleet
   in the same sector that are fired upon have damage divided up.
 * Made techlists toggle on by default (so things are shown in order of
   technological advances.)

Changes to Empire 4.2.5 - Mon Mar  1 06:42:24 PST 1999
 * Added optimization to increasing mobility to check if an object is
   already at max mob, just return since it can't be increased.
 * Added "-ltermcap" for client libs for hp build (it was already in
   hpux build.)
 * Added clearing of telegram flags after the update so that the next
   telegram is flagged as new and not part of the update.
 * Fixed Update-sequence.t to reflect MOB_ACCESS.
 * Fixed bug where fortification amount was not being limited to
   maximum mobility for land units (land_mob_max).
 * Fixed bug where land unit fortification strength was being calculated
   by using 127 instead of land_mob_max.
 * Fixed bug where scrapping land units was creating military.
 * Fixed description of sect_mob_neg_factor in econfig file.
 * Increased speed of PT boats.
        
Changes to Empire 4.2.4 - Tue Feb  2 05:47:44 PST 1999
 * Added check to make military values match up correctly for land
   units.
 * Fixed bug in doconfig not putting ipglob.c in the right place.
 * Fixed bug where attacking deity sectors will violate a treaty.
 * Fixed newspaper.t information file.
 * Fixed potential bug in fixing up timestamp information when restarting a
   game with MOB_ACCESS turned on.
 * Fixed bug in explore command not setting mobility to correct
   value when MOB_ACCESS was enabled.
 * Fixed bug in enlist setting mobility incorrectly sometimes.
 * Added doc/backup file for deities which recommends how backups and 
   restores of the data directory should be done.

Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
 * Added linux-pthreads target and build for using pthreads under Linux.
 * Added NO_FORT_FIRE option which disables the ability of forts to
   fire when enabled.
 * Added more error checking and recovery for corrupt data files.
 * Changed alphapos target to alpha-pthreads for better clarity.
 * Changed fairland to allow 0 sector distance to other islands and
   continents (James Risner)
 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
   match the way ships are described (since this is how they really work.)
 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
   and "fir" as the number of guns that a land unit fires.
 * Cleaned up misc. build warnings.
 * Changed artillery damage to be 5 + d6 per gun firing from just d6
   per gun firing and updated Damage.t to reflect this change.
 * Changed artillery firing ranges to be like ships ranges - divided
   by two, and modified them to make more sense.
 * Changed artillery units to be "slightly" :) more powerful.
 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
 * Changed "artillery" unit to tech 35.
 * Changed so that guns are no longer required to build units, and
   that guns must be loaded onto artillery units for them to fire.
   Client developers note: the show command has not changed yet to
   remove the 'guns' column (since guns are no longer required) but
   will in a future revision (possibly 4.2.4) so "be prepared" for
   "show land build" to change. :)
 * Fixed landunitgun to handle all the damage calculations like it should.
 * Fixed bug sinking planes when the ship they are on sinks.
 * Fixed bug destroying planes when the land unit they are on is destroyed.
 * Fixed bug where land units could fire support without enough military.
 * Fixed bug in abandoning sectors by marching out a land unit where it
   would not let you sometimes (uninitialized variable problem.)
 * Fixed gets problem in files.c (James Risner)
 * Fixed bug in determinig operations range of a ship.
 * Fixed bug in building planes where you could manufacture military.
 * Fixed warnings in threading package(s).
 * Fixed fire.t to reflect new firing changes.
 * Fixed lstat.t to reflect new firing changes.
 * Fixed sstat.t to reflect the way things really work.
 * Fixed Ship-types.t to reflect the way things really work.
 * Fixed the way shutdowns work to hopefully better protect data files.
 * Fixed bug in attacking when sector mobility is less than 0 and it would
   prompt for attacking with a negative amount of military.
 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
 * Fixed bug in client when it prompts for country name it was putting
   an extraneous end of line on the end that needed to be stripped off.
 * Fixed problems running on Linux running on an Alpha machine.  Thanks
   to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
   on a machine to work out the bugs.  (Note that the only build that
   works on Linux/Alpha is the linux-pthreads)

Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
 * Added some code optimizations into the update code when building paths.
 * Added some new cacheing for building paths to help speed up updates.
 * Added so that you can use "name" and "password" with the change command
   as well as "country" and "representative".
 * Added flag to power command so that if you are a deity and enter
   a negative number of countries you want to see, you see the power chart
   for that many countries without power numbers on the next line.  Only
   useful for deities that want to see the chart un-broken up by that line.
 * Added new functionality to fortify command.  You can now use a negative
   fortification value to cause the unit to be fortified and leave at
   least that much mobility on the unit. I.E. "fort * -67" will fortify
   all units and make sure the mobility of each unit doesn't go below
   67.  If the mobility is already below that level (or equal) the unit
   is left unchanged.
 * Added that the realm command prints "Realm #n is x:x,y:y" after
   you set a new realm.
 * Added TREATIES option and enabled it by default.
 * Added "no depth-charging subs" and "no new land units" treaty
   clauses.
 * Added Trannie Carter's basic client fix to use fgets instead of gets.
 * Changed market and command to only print the lowest priced lot of
    each given commodity by default.  If you specify "all" it shows
    all lots on the market, and if you specify a specific item, it shows
    all lots of that item type.
 * Changed start command to only write out sector if it changed.
 * Changed stop command to only write out sector if it changed.
 * Changed how plane names were changed on server startup if the
   PLANENAMES option was enabled.
 * Changed move command to use standard askyn function for abandoning
   sector prompt.
 * Changed plane overlight sightings to take stealth into account,
   and if the planes managed to evade all flak and interceptors, they
   are not marked as "spotted" over enemy sectors.
 * Changed all units with the supply flag to have their marching speeds
   based on efficiency since that is their purpose.  What this means is
   that supply units and trains are more effective at 100% than at 10%
   (just as fighting units are more effective at 100% than at 10%, but
    their effectiveness is determined by how well they fight, not how well
    they "run away, run away!" :) )
 * Changed so that flash toggle is on by default for POGO at setup
   time.
 * Changed so that when a sector is taken, all land units owned by the
   current owner are treated as planes are during takeovers (i.e. there
   is a pretty good chance they are blown up, and if not, they change owner
   to the attacker and are beat up pretty good.)
 * Fixed treaties to work again.
 * Fixed bug in taking over land units not using correct pointer (can
   cause a crash or data corruption.)
 * Fixed collect command to wipe deliver and distribution information
   correctly.
 * Fixed potential bug in bmap not working when destination bmap has
   blank spaces in it.
 * Fixed bug in shark command not getting right nation structure.
 * Fixed bug in server where empty commands (for example, all spaces
   or tabs) were being reported as bogus commands.  They are now just
   ignored.
 * Fixed bug in scrap not dropping land units off of scrapped units carrying
   them.
 * Fixed bug in news where boarding of land units was reported backwards.
 * Fixed bug in calculating new people when growing them during an update.
 * Fixed missing -ltermcap in HP/UX build.
 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
   later and being reset to 0 anyway)
 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
   since that is what it really is.
 * Fixed retreat.t documentation to reflect the "retreat upon failed
   boarding" flag.
 * Fixed bug where satellites were not orbiting the world during the
   update.
 * Fixed bug in torpedos being too smart.  They knew how to jump over
   land! :)  Now the "line_of_sight" routine is used to determine if a 
   torpedo has a straight path to the destination.  If it doesn't, the
   torpedo no longer jumps over land, but instead slams into it.  This was
   an interesting bug because you could torp ships on the other side of
   a very skinny island as long as they were in range, even if there was
   no sea route possible.
 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
   units for example) but you still have to pick something to bomb.  For
   ships it worked ok (just aborted that it couldn't find any more ships)
   and this was fixed for land units and planes.
 * Fixed server crashing bug when flying a plane and not carrying
   any cargo.
 * Fixed bug in move losing commodities when it runs out of room in the
   destination sector.  Goods are now attempted to be returned to the
   start sector, and apporpriate steps taken if the start sector is no
   longer available.
 * Fixed march to prompt you before you abandon a sector you own by 
   marching out the last land unit.
 * Fixed check functions to only check the relevant portions of the structure 
   and not the timestamp info that doesn't affect how the object functions.
 * Fixed bug in spy command that always told you if a spy unit was in a
   non-owned sector.
 * Fixed bug in displaying of land unit missions not showing correct land
   unit range.
 * Fixed bug in wire command where new announcements that you read at
   the last second don't get wiped out properly.
 * Fixed bug where announcement file could be corrupted by very long lines.
 * Fixed bug where bmap was not set when player was told what kind of
   sector they were attacking (this was an old abusable bug that was
   removed long ago to fix the abuse, and it's been fixed in a non-abusable
   way finally.)
 * Fixed bug where change command would warn you about monetary and
   BTU costs, but not prompt you to break out if you didn't want to really
   change your country name.
 * Fixed bug in sub-launched nukes that are intercepted being reported in
   the news incorrectly.
 * Fixed bug in load where you could abandon a sector and not know it by
   loading your last civilians or military onto a ship.
 * Fixed potential memory leak in autonav code.
 * Fixed potential bug where you could possibly determine if a sector is
   owned or not using one way plane missions.
 * Fixed Damage.t info page to properly show damages for planes and
   land unit shelling.
 * Fixed deliver.t to include syntax for command.
 * Fixed country.t to include syntax for command.
 * Fixed bug where ships on orders were not adding radar information to
   the bmap during an update.
 * Fixed bug where ships on sail were not adding radar information to
   the bmap during an update.
 * Fixed bestownedpath code to use the bmap properly.  Note this is a very
   important bug fix.  When navigating a ship, players are no longer given
   free information that they would not normally know.  For example, if you
   try sailing your ship off into uncharted areas of your bmap, the bestpath
   code will only use as much information as you have on-hand (i.e. your
   bmap) to plan out your path for you.  If you have no information on an
   area, it just keeps forging on, until bumping into something.  Of course,
   after the initial exploration through an area, the bmap will be set and
   used for all future sailings through that area.  Harbors and bridges
   are still checked for construction worthiness if you know where they
   are (i.e. they are on your bmap.) (Overall, what happened before
   was that the bestpath code would route your ship around islands that
   you didn't even know were there, and you could use various commands
   to see how that ship was going to sail during the update and thus you
   gained information that you wouldn't normally know.)
 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
   and "BestAirPath" to use it properly.  It is also good to note that
   bestownedpath is used to determine paths for ships and for planes, 
   and that best_path (which uses the A* algorithm) is used for all land
   based paths, and that the two are never interchanged.
 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
   and RECON was never used before.)
 * Removed extraneous "resnoise" and "resbenefit" functions and combined
   the two for setresource and setsector commands.

Changes to Empire 4.2.1 - Tue Nov  3 12:56:20 PST 1998
 * Fixed problem with global/plane.c not defining last structure element
   properly, and thus causing crashes when accessing certain plane
   routines.  This happened during the move to make the PLANENAMES option
   run-time configurable.
        
Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
 * Bumped rev to 4.2.0 since this is a major release (the server is now
   run-time configurable for just about everything and is released under
   the GNU GPL.)
 * Put in official licensing information.
 * Re-arranged and commented the econfig (Empire Configuration) file.  The
   auto-generated "data/econfig" file is now pumped out chock full of
   comments (which may or may not be useful.)  Since the server is
   pretty much fully run-time configurable (MAXNOC is not, but it gets
   a default of 99 anyway) deities will probably be spending more time
   in the config file.
 * Added server support for building under NT, including mods from
   Doug Hay and Steve McClure to get the server building and running
   under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
   line "nmake nt")
 * Added Doug Hay's ntthread.c implementation for NT threading.
 * Added max pop column to "show sector stats" output.
 * Added lboard command for boarding land units from sectors.  Only raw
   mil can board land units, and only mil and land units aboard the unit
   being boarded fight back.
 * Added GODNEWS option.  When enabled, the deity giving people stuff
   is shown in the news.
 * Added bridge tower sector ('@')
 * Added BRIDGETOWERS option.  When enabled you can build bridge towers
   from a bridge span.  You can then build bridge spans from the tower.
   If the tower is destroyed ( <20% eff) bridges connected fall unless
   supported on the other side.  You can only build bridge towers in open
   water not adjacent to land and other towers.  Expensive.
 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
   it is deity creatable only (can't redesignate unless you wasteland it
   with a nuke :) )
 * Changed "info all" to no longer use printdir, instead it just uses the "all"
   info page which contains this information.
 * Changed so you can now load up to 2 spy units onto non-land unit carrying
   submarines if the LANDSPIES option is enabled.  Useful for sneaking up
   to shore and spying on your neighbors.
 * Changed so spies unloaded from ships are not given as gifts, they are just
   unloaded quietly.
 * Changed build command to handle building towers ("build t")
 * Changed show command to show tower stats ("show t b")
 * Changed reject so you can now reject things from any country except
   deity countries (this now includes sanctuary countries and visitor
   countries you don't want to deal with)
 * Changed ndump to dump nuclear stockpile ID as well.
 * Changed flash so that if someone allied to you is either not logged on or
   not accepting flashes, you are notified.  This is info you could gain
   otherwise since you can see other countries that are allied to you via
   players.
 * Fixed bug in news command when HIDDEN mods are enabled.
 * Fixed distribute command to only write out to the database if we
   actually changed the sector (i.e. if we really moved the dist
   center, we write.  Otherwise, it makes no point.)
 * Fixed threshold command to only write out to the database if
   we actually changed the sector (i.e. if we really changed the
   threshold, we write.  Otherwise, it makes no point.)
 * Fixed - population growth and truncation in "Update-sequence.t" info
   file is now clearer

   don't want units carrying units to be carried by other units, etc. :) )
 * Fixed info pages to reflect new sector types.
 * Fixed info pages to reflect new spy unit capabilities.
 * Fixed show commands to only show trade ships if the TRADESHIPS option

   defense planes and take no damage (i.e. they got to fight twice,
   once for free.)
 * Fixed bug in freeing memory after performing missions that could crash
   the server (it mainly happened after an interdiction mission using
   planes and escorts, where some escorts came from airports that didn't have
   bombers going up.  Freeing the leftover escorts was crashing the server.)
 * Fixed bug where you could load non-existant units if you were allied

   the server.
 * Fixed bug that after you read telegrams new telegrams may not send
   an inform message (the old telegram flags were not cleared.)
 * Fixed bug where fort support distance calculations are calculated
   twice instead of just once.  This bug caused a lower percentage
   of support fire than designed.

 * Put in some integrity checking for planes returing from bombing runs.
 * Added ability to edit land unit that a land unit is loaded on in
   edit command.

 * No longer able to pin bomb land units on a ship.
 * Land units are required to have at least one military loaded to perform 
   a mission.
 * Firing land units are required to have at least on military loaded to
   be able to fire (or return fire.)

   before.)
 * Fixed bug in neweff not reporting stopped sectors.  It now (correctly)

 * Fixed line_of_sight prototype in sona.c
 * Fixed fairland not to conuse stupid C++ compilers.

Changes to Empire 4.0.11 - Tue Feb 10 10:53:10 EST 1998
 * AIX build seems to only work with gcc right now (but at least that works)
 * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box.
 * Took out autosupply of airports when bombing or dropping shells.
    (This was the only commodity this was done for, and it was creating
    problems since supply is still somewhat broken somewhere)
 * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
    submitted patches, which collectively included cleaning up most
    of the server prototypes and bogus declarations.  Many thanks.

    damaged, unless the ship is damaged.
 * Fixed problem with no newline after partisan activity telegram in
    anti.c
 * Fixed problem in chan.c printing out change costs incorrectly.
 * Fixed problem in dispatch.c screwing things up on redirection.
 * financial should now handle 6 and 7 digit loans.
 * Planes on ships that are in sectors that revolt are no longer taken
    over.
 * Fixed bug in powe.c where the power report was mis-calculating the
    efficiency of planes.
 * Fixed doconfig.c to use STDC instead of multi-level #ifdefs.
 * Fixed bug in parse.c that was screwing up double quotes in conditional
    arguments.
 * Military in a sector now only produce up to maxpop, just like civvies
    and uw's.  No more stuffing 6K mil into a mountain to max it out.  You
    can still hold more mil there over the updates, but the extras just
    won't produce anymore.
 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
    cover the debt.
 * Fixed bug in day of week calculation for server up time in common/keyword.c
    that is used for gamedays.

 * Fixed bug in "move" where you could keep a sector even after someone else
    took it from you.
 * Budget now correctly reports the # of units being built.
 * Mil on units & ships are now reported as normal military costs, not
    ship or unit maintainence costs in budget.
 * Fixed bug in update code where taxes could potentially be initialized
    incorrectly (affected budgets too.)

 * Revamped and improved flak.
 * Added "Flak" info page.
 * Added "Fallout" info page.
 * Fixed repay/offer/consider to all need a capital to be used.
 * Fixed bug with air defense missions not running when not AT WAR.  They now
    fly when HOSTILE.
 * plane/ship/unit short names are all now 4 characters, padded if needed.
 * pdump/sdump/ldump/ndump now just print the short name for the type.
 * sdump now has ship name at very end in quotes.
    These were done at the request of some client developers for ease of use.
 * Fixed extra space in the dump output.
 * Fixed fallout - not quite so nasty anymore.
 * Fixed fallout - things on ships/units are damaged now.
 * Fixed and balanced planes/ships/units/nukes in conjunction with each other.
 * Fixed bug in doconfig.c calculating wrong s_p_etu sometimes.
 * Fixed bug where harbors weren't being used to resupply.
 * Fixed bug where selling units loaded with planes and units wouldn't take
    the loaded planes or units - they are now dropped.
 * Fixed bug in arm/disarm where you could arm/disarm planes on the trading
    block.
 * Deities can now remove things from the trading block/market.
 * Fixed bug in "work" not charging engineers enough mob.
 * Fixed bug in "work" not adding teardown and buildup avail costs together.
 * Subs no longer need mobility to return fire when fired upon.

 * Fixed "sell.t" info page.
 * Fixed bug in "buy" where not entering the price correctly could cause
    a crash.

    be.
 * Fixed timestamps to be updated for units/planes on ships/units that move,
    since those units/planes move too.

Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
 * Fixed bug in nstr_exec that was wiping out the previous conditional.
    This was major because it affected timestamp values which are more
    than 65535.

Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
 * Fixed bug in aircombat.c when calculating the air combat odds.  Negative
    numbers were screwing things up good...
 * Fort sector's coordinates are no longer printed when auto-firing at
    ships.
 * Subs can now surface and fire deck guns (again)  They can also be
    hit by return fire when doing so.
 * Fixed bug in setting of plane attack and defensive values so that
    negative numbers don't keep going further negative.
 * Fixed incorrect military control calculation in the sell command.
 * Trading posts are no longer required to sell goods from.  You can sell
    from harbors and warehouses now too.
 * Spy now prints out the owner of land units you see when spying.  Before
    this was assumed to be sector owner, which is no longer true.
 * Loading land units now prints out what was loaded onto each unit,
    just as loading ships do.
 * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output.
 * Added "GO_RENEW" option.  This option means that gold and oil resources
    are renewable.
 * Added "lost_items_timeout" config variable, and set the default to
    48 hours.  This determines how long lost items stay in the lost items
    database.
 * Fixed land unit names to be more consistent.
 * Fixed mission.t info page.
 * Fixed bug in that if mission_mob_cost was set to 0, even negative
    mob units should be able to be put on missions.
 * Removed restriction on things needing to be at least 60% to be put
    on a mission.  Note that while you can put them on missions at < 60%
    now, when trying to do the mission, it still checks the eff.  This
    is to help in automatic setup (build, put on mission, forget) instead
    of having to come back repeatedly.
 * Spies caught in Neutral or Friendly countries cause the Neutral or
    Friendly country to go Hostile towards the owner of the spy.
 * Tweaked ammunition numbers for artillery units.
 * No more automatic declarations of War should be made.  You will go 
    hostile, but since going to war doesn't increase your countries
    defenses, and is purely political, it is left to the player to go
    that final step.
 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
 * Fixed bug in "lmine" that was crashing the server if the land unit was
    out of mobility.
 * Fixed buy so that if you specify a product, you can only bid on that
    type of product.
 * Added "lost.t" info page.
 * Added "lost items" database (EF_LOST)
 * Fixed bug where you could move in allied forces after an attack if they
    bordered the victim area.
 * Fixed nstr_comp to deal with values > 16 bits coming in from
    client for comparisons.
 * Changed last minute market/trade timers to increment 5 minutes.  2 minutes
    was too quick.
 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
 * Commented out the logging of the market checking in server/marketup.c,
    lib/commands/buy.c and lib/commands/trad.c  It was generating lots of
    pretty much useless data that made parsing the server.log file more
    more difficult than it needed to be.
 * Fixed crashing bug in ldump.
 * sdump, ldump, ndump, pdump and dump now print out the current
    timestamp on the "DUMP XXX" line.
 * Fixed denial of service bug in lib/player/accept.c in
    player_find_other function.
 * Fixed bug in shark reporting incorrect buyer of the loan.
 * Fixed bug in sdump.c (case 0 should have been case 10)
 * ldump and sdump now always print the fuel column if asked for,
    even if opt_FUEL is turned off.  In the case that it is turned
    off, the fuel is listed as 0.
 * Added "timestamp" field, which is updated every time an item is
    changed.
 * Fixed up the Clients.t info page.
 * sdump now prints trade ship building origin.
 * sdump now always prints name even if SHIPNAMES isn't defined.  If
    it is not defined, then the name is empty.
 * Added "timestamp" to info/Concepts/Selector.t
 * Added some more relevant info to info/Server/Empire4.t
 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
    is no longer torn down when a sector is re-designated.
 * Fixed sell.t to more accurately reflect the time-delay market.
 * Fixed read.t and wire.t to reference accept and reject.
 * Fixed reject.t not referencing accept command.
 * Fixed collect.t to more accurately reflect what goes on when collecting
    sectors.
 * Fixed financial.t to reflect defaulted loans.
 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
    timestamp info.
 * Fixed "census.t" (had incorrect reference to "info syntax" instead
    of "info Syntax".

Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
 * Increased damage from depthcharges because on increased damage from
    torpedos.  Sub frange decreased to be more balanced with destroyer frange.
 * Intelligence reports (spy) on units will now report the estimated number
    of mil on the unit.
 * Fixed equation for ship visibility so it will drop as tech increases.
 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
    land units, planes, and nukes.
 * If fields are provided, dump will only supply those fields requested.
 * Decreased speed of subs.
 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
    required for infrastructure improvements.
 * Units that lose an assault or a boarding attempt from a ship will no
    longer swim back to the ship they came from.
 * Units that take extra casualties will no longer lose all their mil at
    once.
 * Infrastucture is retained when redesignating a sector.
 * Dieing spies will no longer crash the server.
 * Units, planes, and ships must have mobility to perform missions.
 * Units on ship being scrapped are transferred to harbor.
 * Food is no longer autoloaded onto units when they are built.
 * Fixed show plane stat to show correct range.
 * Infantries now take damage at same rate as casualties.
 * Fixed bug with hap_fact.  Having more happiness now helps with fighting
    che.
 * Fixed anti to write back target country so che will continue to fight
    when they survive.
 * Fixed llookout to show correct estimate on number of mil on unit.
 * Added buildable architecture "hp".  This type will build the server on
    a HP/UX machine using the standard compiler instead of gcc.

Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
 * Fixed bug in update/distribute.c where pathcost was not being called with
    the MOB_ROAD argument (and thus distribution costs could be GREATLY
    affected.) - Thanks Ice!

Changes to Empire 4.0.4 - Mon Dec  9 11:00:00 EST 1996
 * Fixed Solaris port using gcc.
 * Fixed doconfig.c to create directories with right modes.

 * Put in LND_MINMOBCOST in land.h
 * Put in change in lnd_mobcost in lndsub.c
 * Put in new nuke costs in nuke.c
 * Put in fix so that total work can only be done by the max pop. No more extra
    civvies tossed in will do it anymore in human.c.
 * Put in fix for src/util/Makefile - beefed it up.
 * Put in fix to show where your ship is when it gets shelled in mfir.c.
 * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in
    common/move.c)
 * Fixed Update-sequence.t.
 * Put in fix for mobcost bonus for 0% highways.
 * Fixed stop.t
 * Fixed commodity.t
 * Spruced up torpedo damage somewhat. :) :)
 * Fixed "assault bmap bug" in attsub.c
 * Fixed Produce.t (bars cost)
 * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
 * Fixed consider.t
 * Fixed repay.t
 * Fixed offer.t
 * Fixed "offer" and "consider" not being legal commands in player/empmod.c
 * Fixed Damage.t
 * Fixed sstat.t
 * Fixed lstat.c, pstat.c and sstat.c
 * Fixed cutoff command in cuto.c
 * Fixed attack value in attack_val in lndsub.c
 * Fixed lload in commands/load.c
 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
    always fight until dead or retreating.  0 makes them get stuck. 
 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
    else for that matter.)
 * Fixed llook in commands/look.c
 * Fixed che bug in subs/nstr.c
 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
    of people would starve.)
 * Fixed update/human.c - feed_people rounding problems (I hope.)
 * Fixed morale problem in update/land.c
 * Fixed count_bodies in attsub.c
 * Fixed lnd_mobcost.
 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
 * Fixed interest rate in commands/offe.c
 * Fixed bug in buy.c.
 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
    infrastructure.  When off, the defensive infrastructure is the same
    as the sector efficiency, and you can't improve it.  This is OFF by
    default.
 * Fixed Empire4.t
 * Added Wolfpack.t
 * Land units are now built with a default reaction radius of 0.
 * Changed name of lt artilleries to "lat" from "lart" so you can now build
    "lar"s again.
 * Lowered the speed and firing range of pt boats.
 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
    powerful.)
 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
    (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
     1.5 * ETU_RATE for ships.)
 * Conquered civvies only pay 1/4 taxes.
 * Railways don't get torn down when you rebuild sectors anymore (but roads
    and defenses do (if enabled.)

Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
 * Added "extern double tradetax" to check_trade in trad.c
 * Improved description of data directory in build.conf
 * Fixed bug in attacking land units that retreat so they now get
    charged mobility for attacking.
 * Fixed dump to report road, rail and defense of a sector at the end.
 * Fixed doconfig bug in not checking the right directory to see if the
    "data" directory existed or not before trying to create it.
 * "change" now works for sanctuary countries.
 * Fixed the description of "sinfrastructure".
 * Added more info to "Infrastructure".
 * Units/planes are no longer reduced to 75% when bought from the trading
    block.
 * Supply units were slowed down to the speed of infantry units.
 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
 * Bars interest is up to $250 per 1K again.
 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
 * Fixed various info pages.
 * Fixed bug in people not getting truncated when broke (this was thought
    to be fixed, but wasn't. Now it is, dammit!)
 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
 * Market/trade taxes and trade ship payoff figures were added to version.
 * "cede" has been removed as a default command.
 * Makefile rule was fixed for depend build.
 * Fixed bug in mapdist not taking world edges into account nicely enough.
 * Added a "scuttle" order for autoscuttling trade ships.  Makes using them
    easier.  Cleaned up scuttle code while in there.
 * Fixed bug with scuttling a ship with units on it not scuttling the units
    too.

Changes to Empire 4.0.0 - Initial release
 * Initial Wolfpack release - Long live the Wolfpack!!!!
 * Cleaned up the build environment.  Now all that is needed is to edit the
    build.conf file, answer the questions there and type "make <arch>" to
    build for a specific architecture.  Thus, no more reliance on gnumake
    or special shell scripts.
 * We are now shipping the pre-built info pages with the server for those who
    Don't want to build them.  You can also still just type "make" and have
    the info pages build, but it doesn't completely work (i.e. rebuild new
    Subjects) if you don't have perl5 installed.
 * Put in the "help" command that does the same thing as "info".
 * Removed C_SYNC.  This is done for 2 reasons.  1) None of us like it or
    wish to support it.  2) We envision a better scheme for doing similar
    things will come along.
 * Put in MOB_ACCESS - This allows real-time updating of mobility.
 * Put in MARKET - This is the time-based market (yes, still teleports,
    but it's not as bad as it was.)
 * Lots of the documenation has been updated, but there is more to do.
 * Added NO_LCMS, NO_HCMS and NO_OIL options.  When any of these options are
    enabled, you don't need any of that type of material to build things.
    If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
    lcms.  If both NO_HCMS and NO_LCMS are enabled, then you don't need 
    any materials to build a bridge.
 * There is no mobility cost for assigning missions.  But, there is also
    no longer any benefit for being on a mission either.
 * Damage is the same for all commodities (people too.)  This means you
    can deity shell/bomb sectors again.
 * Units are now dependant on tech.  What this means is that their statistics
    now increase with tech.  In addition, there is only 1 type of each basic
    unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
    This reflects the idea that as you learn more, you learn how to not only
    build better units, but you learn to build units better. :)  This also
    opens the door for a "lupgrade" command along the same lines as the
    "upgrade" command for ships.
 * Units now have a minimum mob cost for attacking a sector.  Marching
    mob costs have not changed.
 * Starting units have been removed.  This means that at the beginning, people
    may live a little longer since their neighbor can't come visiting quite
    as quick.
 * Shells are no longer required to build units.
 * Mil are no longer required to build units.
 * Mil are no longer an intrinsic part of a unit.  They are now a loadable
    commodity.  The way a unit's defense/att bonuses work now are
        attack = (att * mil * eff)
        defense = (def * mil * eff)
    In addition, when a unit takes damage, both the eff and the mil go
    down.  You can quickly toss in new hacks, but you need to wait to repair
    the unit at the update.  Thus, you can now look at unit's efficiency
    as their training.
 * You need at least 1 mil on a unit to march it (spies are the exception.)
 * Units always react if in range and they have the mobility, no matter
    what their efficency.
 * Units may now march anywhere - in your own sectors, deity owned sectors
    or allied sectors, with 1 exception, spies.  Also, your units can get
    trapped if your ally declares non-alliance with you while your units
    are still in his country.)
 * Units always march at their speed, efficiency doesn't matter.
 * LANDSPIES was added - This creates land unit based spies.  Spies may march
    anywhere, with a chance of getting caught (except in allied territory.)
    See "info Spies" for more info on them.
 * Planes may now be based out of allied airports.  Landing planes on
    ships/sectors you do not own no longer changes thier owner.  You can only
    land on owned/allied sectors/ships, and you may only
    fly/bomb/para/recon/drop from owned/allied sectors.  So, if a country
    you are allied with goes hostile at you, your planes are now stuck there.
    Note that if you are using an allied airport, their commodities get
    sucked up, not yours (obviously.)
 * Planes are now tech-based.  Their statistics increase as their tech
    increases.  Deleted extraneous planes.
 * There is a new toggle, "techlists", which allows you to see what you
    can build/stats/capabilities sorted by tech instead of groupings.
 * Ships are now tech-based.  Their statistics increase as their tech
    increases.  Deleted extraneous ships.
 * Che can now be lessened by making happiness.  If you have more happiness
    than your conquered populace, they don't fight as hard or recruit as
    much.  If you have less than them, they fight harder and recruit more.
    It's not much though - it ranges from 2.0 in your favor to only 0.8 
    against you (whereas it was always 1.0 before.)  So, it definitely
    favors the attackers to make lots of happy now.
 * Bridgeheads can only be built on coasts.
 * Players command was fixed so you only see allies, and don't get
    approx #'s of players anymore.
 * POSIX threads support has been added.
 * The attack bmap bug has been fixed.
 * BTUs regenerate 3 times faster now.
 * GRAB_THINGS is off by default.
 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
    as a default (you couldn't make wasteland before with FALLOUT, now
    you can.)
 * You can now deliver military and civilians.
 * Added SHIP_DECAY option - off by default (turns off ships decaying out
    at sea if not enough mil.)
 * The reverting owner bug has been fixed in territory, thresh, dist
    and deliver.  There are probably more, and when found, will be fixed.
 * The "sectors don't starve when stopped or broke" bug has been fixed.
 * The "people never get truncated" bug has been fixed.
 * Added infrastructure to sectors.  What this means is that a sector
    can now have it's mobility improved by building both roads and
    railways.  It also means that a sectors defense is now based on the
    defensive infrastructure you build into the sector (no more intrinsic
    better defenses based on the sector, you determine which sectors are
    defended heavily, and which aren't.)
 * The defensive value of a sector no longer relies on the efficiency of
    the sector. Instead, it relies on the defensive efficiency of the sector.
    Thus, the "production" and "defensive" aspects of sectors have been
    separated.
 * "show sect stats" now shows the maximum defensive value for sectors.
 * Changed sector structure to take floats for off/def values so we can use
    a base of 1 instead of 2.
 * Added "improve" and "sinfrastructure" to support the infrastructure
    concepts.
 * Added L_TRAIN units which can only travel along railways.  Very fast on
    efficient railways, slow on non-efficient ones.
 * Added the ability for units to carry other units.
 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
 * Forts only cost $500 to build and 100 hcms now (since they don't get any
    better defenses automagically.)
 * Modified "show sect build" to show the costs for building up the
    infrastructure of a sector.
 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
    spyplanes too) to show the new infrastructure stuff, rounded of course.
 * Added Drake's info->html scripts, with some modifications, so you can
    now type "make html" and have your info pages built as html files too.
    This adds a new directory, "info.html", to the build tree.
 * Modified upgrade so that planes and land units may now be upgraded.
 * Added pstat command to list the statistics of your planes.
 * Added lstat command to list the statistics of your land units.
 * Added sstat command to list the statistics of your ships.
 * Added nmap command to show a map of your sectors after their new
    designations have taken place.
