freeciv: 2.3.4-1~getdeb1

  * New upstream version
       The main reason for this release is to fix a client crash triggered by
       chat messages; see below. Other than that, there is the usual set of
       bugfixes.

    Server / General

    Gameplay

    * Bug fix: when a unit was automatically moved to a transporter to
      save it from drowning or running out of fuel, the transporter could
      continue to appear empty. GNA#20454
    * Bug fixes in unit conversion and upgrade GNA#20452:
    + Prevent cases where units could be converted or upgraded to a
      type only capable of carrying different cargo to the current
      cargo.
    + Prevent conversion of a unit to a type that could not exist on
      the current tile.
    * Units of types the owner cannot build are no longer prevented from
      upgrade. GNA#20460
    * Bug fix: quell spurious "No diplomat action possible" message when
      an ordinary attempt to move a diplomatic unit failed. GNA#20150
    * Following on from a fix in 2.3.3, when a border source such as a
      fortress is occupied by a unit of a nation other than the owner
      when a ceasefire runs out, ownership now transfers to that of the
      occupying unit. GNA#20348
    * When acquiring a technology such as Philosophy which gives further
      techs by an unusual route (such as through a hut), all progress
      toward the current research target was lost. Now it is preserved
      (although 'freecost' is applied). GNA#20362
    * Bug fix: when a city is traded and hence units change ownership, it
      wasn't checked whether those units provided diplomatic contact to a
      new nation. GNA#20431
    * Bug fix: assertion failure during map generation when no unit in
      the ruleset satisfied the first role in 'startunits'. GNA#19886
    * Bug fix: the tech upkeep with tech_cost_style 2 or 4 was much lower
      than intended; it only took into account a single tech rather than
      all preceding techs. As a result, tech upkeep in such rulesets will
      greatly increase. GNA#20063
    + The currently downloadable 'civ2-3' modpack (2.3-2c) thus has
      tech upkeep disabled. You may want to update your copy.
    * An unknown effect requirement type in a ruleset now causes a
      loading error rather than being silently interpreted as "None".
      GNA#20462

    Clerical

    * When a new nation is created in the editor, city style and leader
      sex are now set appropriately (previously they were always European
      and male). GNA#19313
    * A hardcoded year of -4000 is no longer sent to the metaserver in
      pregame, as it is ruleset-dependent. GNA#17862
    * One code tidy-up with no user-visible effect. GNA#20458

    Clients

    * The client could crash when your name was mentioned in chat but you
      had set the 'highlight your player/user name' setting to no color.
      This could also prevent any connection to a server with the event
      cache enabled if your player name had been mentioned in the past.
      GNA#20478
    + Older clients can work around this bug by setting a highlight
      colour in their local options (you may need to start a local
      game in order to access the configuration dialog).
    * Fix possible instability when loading some tilesets. GNA#20055

    Tilesets / Art

    * Some internal SVG format fixes in the supplied flags to allow their
      use in web browsers; this has no effect on Freeciv itself.
      GNAPATCH#3574

    AI

    * Fix some incorrect inferences about the ability of transported
      units or units in cities to defend; these are most likely to affect
      unusual rulesets (e.g., those with ocean cities). GNA#20483

    Help / Documentation

    * Minor improvements to user documentation and in-game text.
      GNAPATCH#3592 GNAPATCH#3594 GNAPATCH#3634 GNAPATCH#3662
    * Miscellaneous improvements to developer/ruleset docs. GNAPATCH#3575
      GNAPATCH#3595 GNAPATCH#3602 GNAPATCH#3603 GNAPATCH#3640
      GNAPATCH#3660

    Translations

    * The Spanish, Polish, and French translations are once more
      complete.

    Build/portability

    * Fix various compiler warnings. It's now possible to build Freeciv
      with GCC 4.7 optimisation level -O3 without any warnings. GNA#19386
      GNA#19385 GNA#20443 GNA#20413 GNA#20447 GNA#20444
    * Future-proof against automake versions which ignore
      ACLOCAL_AMFLAGS. GNAPATCH#3585
    * Suppress warnings about use of deprecated declarations in debug
      builds, allowing compilation on for instance recent OpenSUSE.
      GNA#20428
