WHAT'S CHANGED SINCE 2.6.3[edit | edit source]

2.6.4 is a generic bugfix release.

Server / General[edit | edit source]

Changes affecting players (supplied rulesets)[edit | edit source]

  • Made automatic selling of coastal improvements from a city that gets landlocked to work better HRM#880455
  • Adjusted formula for barbarian band size. For nations with less than 32 cities there is no change, but bigger empires get bigger barbarian bands than they used to HRM#767126
  • Fixed postponing buildings from worklist. They were never really postponed HRM#912972
  • Combat messages show more detailed information about combatants HRM#913055
  • Fixed display of game years above 32768 HRM#918800
  • Players no longer need hack access to disable timeout any more than they need for enabling it HRM#647101
  • Fixed crash, seen on client side, when receiving extremely well compressed network packets HRM#918726
  • Send meetings initiated by AIs player is in contact with initially (thanks to dispersion server setting) to client when it is ready to handle them. Not only did the bug prevent those meetings from opening in the client, but it prevented player from ever opening a meeting with that AI. HRM#764968
  • Corrected check that the upgraded unit will fit to its transport before upgrading it HRM#921691
  • Clients connected to the server are no longer sent to the pre-game screen when there's an (failing) attempt to load a savegame when game is already running HRM#767358
  • Corrected calculation of nation's literacy value when number of citizens has changed during the turn, e.g., by losing cities HRM#880780
  • Update a city also on other player's clients when its size get reduced because of a nuke osdn#41810 osdn#41860
  • Made generated random seed less predictable on most platforms. Windows is a notable exception HRM#914184 osdn#41838
  • civ2civ3 ruleset:
    • Fixed tile output penalties not to apply to Luxury or Science bonuses provided by wonders like Hanging Gardens HRM#908518

Changes affecting other rulesets / modders[edit | edit source]

  • Fixed messages claiming that a tech obsoletes a wonder, when in fact the tech was negated obsoletion requirement HRM#874192

General[edit | edit source]

AI[edit | edit source]

  • When considering building unit for city bashing, use its actual attack count instead of assuming it to be one. This makes AI to understand e.g. that unit with movement 2 can both attack and conquer at the same turn HRM#872218

Clients[edit | edit source]

  • Fixes to the Qt client:
    • Confirmation dialog added for disruptive unit selection HRM#907806
