freeciv: 2.3.3-1~getdeb1

  * New upstream version
    Gameplay

    * Bug fix: players' endgame scores could be too high due to the
      future techs state not being initialised correctly at the start of
      the game; this could lead to incorrect ranking. The fix will only
      help with games started with a new version of the server;
      in-progress games will continue to have incorrect scores. GNA#19745
    * Bug fix: allied victory (enabled by default) never occurred.
      GNA#17986
    * Freeciv now infers that ruleset effects are possible in more cases
      where incomplete information is available. This is a low-level
      change whose effects are hard to quantify, but should be more
      correct; it is most likely to affect client behaviour and the AI.
      GNA#20304
    * More types of units are now permitted to auto-explore - only those
      with fuel or which lose hitpoints are prevented. In particular,
      Triremes in the 'experimental' ruleset can now auto-explore.
      GNA#17958
    * Bug fix: goto planning could erroneously consider it impossible for
      a unit to move to a city on non-native terrain. It was still
      possible to make such a move with the cursor keys. (Does not affect
      supplied rulesets.) GNA#19611
    * Bug fix: following on from 2.3.2, more assertion failure fixes when
      many autosettlers try to work on the same project. GNA#20240
    * Bug fixes in unit destruction:
    + Many more cases of unit loss now contribute to the final
      score, notably including units on board a transport unit when
      it was lost. GNA#20300 GNA#20301
    + The "unit_lost" scripting signal was not emitted for units on
      board a transport unit when it was lost. (This bug had no
      effect on the supplied rulesets.) GNA#20221
    * Bug fixes for border sources such as fortresses:
    + When a border source within range of a city was invaded, tile
      ownership from the first source did not change hands
      correctly. GNA#19831
    + When a border source changed hands and the new owner did not
      know all the territory in range, the old owner could
      erroneously retain some tiles. GNA#19983
    + When a border source is occupied by a unit of a nation other
      than the owner at the time a treaty between the two players
      breaks, ownership now transfers to that of the occupying unit.
      (partial fix for GNA#20348)
    * Bug fix: with foggedborders enabled, tile ownership could appear to
      change back to an old owner when it went out of sight. GNA#18588
      GNA#19627 GNA#19637
    * Fix possible trouble when upgrading a highly-veteran unit to a type
      with fewer veteran levels. GNA#19913
    * Bug fix: in tech loss situations, future tech would fail to be
      removed from a player, with an assertion failure. GNA#20220
    * Bug fix: the full range of the 'trademindist' setting (1-999) could
      not be transmitted over the network to the client. This caused a
      cosmetic problem in the help for the 'civ2-3' ruleset. GNA#19977
    * Bug fix: server-side AI assertion failure in rulesets with
      paratroopers and ocean cities. GNA#20230

    Clerical

    * Security fix: malformed network packets could cause denial of
      service (memory exhaustion or CPU-bound loop). GNA#20003
    * Bug fix: if the server was started with one ruleset and then
      another with a different number of governments was loaded (e.g.,
      'default' then 'multiplayer'), it could crash. GNA#19800
    * Bug fix: ordinary save files from a game started from a scenario
      file could themselves be saved as scenario files, and thus be
      listed as unwanted options when starting a new scenario game.
      GNA#19919
    * When a scenario is saved, scenario information is included earlier
      in the file, to speed up the 'Start Scenario Game' dialog.
      GNAPATCH#3497
    * It is now possible to save games with names containing dots -
      previously, everything after the first dot was stripped. GNA#18781
    * Bug fixes to scorelog/ranklog:
    + Player deletion was logged incorrectly in scorelog, causing
      warnings when resuming the game from a save file. GNA#20069
    + When a new user took over a player from another user, the old
      username could persist in the ranklog file. GNAPATCH#3526
    + Taking over a dead AI player no longer changes their username
      in the ranklog. GNAPATCH#3547
    * Tab-completion on the server command line has been improved;
      notably, enumerated and bitwise options are now completed.
      GNAPATCH#3436
    * Fix a possible crash when the '/cmdlevel' server command is issued.
      GNA#19878
    * More robustness against malformed network packets. GNA#20107
    * Minor performance improvements in certain specific situations.
      GNA#19823 GNAPATCH#3334
    * Various internal changes which should only affect developers.
      GNA#19585 GNAPATCH#3205 GNA#15743 GNA#19564 GNAPATCH#3081

    Clients

    * Bug fix: assertion failure in get_internal_string_length() on
      client start on some platforms. GNA#17373
    * Fix a couple of issues with units with a zero move rate (no such
      units exist in the supplied rulesets):
    + The 'exhausted' icon was always shown for such units; now it
      is never shown. GNA#20270
    + Such units are now not skipped when focusing on the next unit.
      GNAPATCH#3567
    * Reduce memory usage after game start with large tilesets. GNA#16995
      GNA#19605
    * The default metaserver URL has been updated in line with future
      plans. (The old URL will continue to work for the foreseeable
      future.) GNAPATCH#3453 GNA#20014
    * Saved configurations now correctly save the default metaserver URL
      as "default", so that future changes to the default will be picked
      up. GNA#20015
    * (Gtk) Fix migration of chat/message window arrangement settings
      from 2.2.x. (This will not help you if you've ever run a previous
      2.3.x version; you'll have to restore your preference manually, if
      you haven't already.) GNA#19888
    * (Gtk) Fix possible colour inaccuracy. GNAPATCH#3344
    * Additional robustness in the face of odd server behaviour.
      GNA#13701

    Tilesets / Art

    * Bug fix: in the hex2t tileset, the fogged parts of the minimap were
      far too dark. GNA#16900
    * In the supplied Amplio2 tileset, the 'Refugee' graphic has been
      enabled, for the benefit of custom modpacks such as civ2-3.
      GNA#3455

    Gameplay / Rules Changes

    Supplied rulesets

    * The supplied earth-80x50-v3 scenario could not be loaded at all in
      a release build. GNA#20050
    * In rulesets with a 'watchtower' vision bonus for fortresses, the
      bonus now only applies to ground units in the fortress, not to air
      units flying over it. GNA#19866
    * Bug fix: in the 'multiplayer' ruleset, players could gain free
      techs multiple times by rebuilding Darwin's Voyage (fixed by
      GNA#19852).
    * Bug fix: in the 'experimental' ruleset, Triremes could not attack
      outwards from a city. GNA#19828
    * The script.lua files for the civ1/civ2 rulesets had been
      accidentally omitted from the distribution, although this had no
      functional effect. GNA#19907
    * Ruleset tidy-ups with no functional effect. GNA#20020 GNA#19991

    Other rulesets

    * A custom ruleset effect can now have both Oceanic and Land
      requirements in a single list. GNA#19916
    * The give_technology() Lua script function now returns 'nil' if the
      player already has the technology, as documented; previously it
      returned the Tech_Type 'None'. GNA#19852
    * The total Max_Rates effect value is now clipped to its legal range,
      so it's no longer necessary for custom rulesets to take care to
      keep the total value below 100% to avoid server misbehaviour.
      GNAPATCH#3343
    * The MinYear effect now allows years earlier than -4000. GNA#17862

    AI

    * Fixes for a couple of server crashes (division by zero):
    + In rulesets with tech upkeep, when evaluating the value of
      'Tech_Parasite' effects (e.g., Great Library), players who are
      losing bulbs are no longer considered. GNA#20234
    + Division by zero could occur when evaluating poor city
      locations. GNA#20239
    * AI behaviour is likely to change as a result of GNA#20304. For
      instance, it might be more likely to research a tech to allow it to
      build a kind of building without being certain that that building's
      other prerequisites will ever be fulfilled.

    Help / Documentation

    * Government-wide effects on unhappiness caused by military units
      were not mentioned in the online help. (In many of the supplied
      rulesets, the Republic government type suppresses unhappiness
      caused by one unit per city.) GNA#17905
    * The shipped FAQ has been updated from the wiki version.
      GNAPATCH#3420
    * NEWS in the distribution now contains a change list between major
      versions, rather than just being a pointer to wiki; a new file
      NEWS-2.3 lists differences between recent minor versions.
      GNAPATCH#3488
    * A manual page is now included for the 'freeciv-manual' utility.
      GNA#19227
    * Other minor improvements to user documentation and in-game text.
      GNA#19860 GNA#19908 GNAPATCH#3368 GNAPATCH#3398 GNAPATCH#3431
      GNA#20019 GNA#20021 GNAPATCH#3500
    * Miscellaneous improvements to developer/ruleset docs. GNA#18015
      GNAPATCH#3359
    * Invisible changes to assist translation. GNA#19870

    Translations

    * New translations: Serbian (33%), Bulgarian (31%).
    * Updated translations:
    + Complete translations: Spanish, Catalan, Scottish Gaelic.
    + Incomplete translations: Dutch (72%), Irish (56%).

    Build/portability

    * The configure script could fail to detect SDL_mixer, for instance
      on Fedora with hardened build options set. GNAPATCH#3519
    * The embedded Lua build now respects the --without-readline
      configure option, fixing a possible failure to build on systems
      without readline. GNA#20219
    * Autoconfiguration macros for X now avoid non-portable '=='.
      GNA#20002
    * The material used to build Windows installers is now included in
      the distribution. GNA#19088 GNAPATCH#3357 GNAPATCH#3365
    * Warning fixes on various platforms. GNAPATCH#3466 GNA#20013
