WHAT'S CHANGED SINCE 2.5.4 Edit
2.5.5 is a bugfix release.
Server / General Edit
Changes affecting players (supplied rulesets) Edit
- A city containing a Leader unit will now never defect in a civil war. Previously this could cause the rebels to end up with both Leaders.
- Units without a home city are no longer forced to acquire a home city when transferred to another player.
- Barbarians no longer spawn in Lake terrain in all rulesets which have it.
- Bug fix: it was impossible to change production in a city after disbanding a unit there the same turn the city was built.
- The win chance of a boat in a city defending against attack was erroneously displayed as 0%. (A new client connecting to an old server running a custom ruleset may still display an incorrect defense value, this time too optimistic.)
- The client's display of city population could be out of date after international migration.
- The 'Plague' random disaster in the classic ruleset has been renamed to 'Pestilence' to avoid confusion with the unrelated game concept of plague. Other text changed to mitigate this confusion.
- Bug fixes and improvements to Latvian, African, and Texan nations.
- Correct descriptions of server options 'techlost_recv' and 'techlost_donor' to make clear that they apply to technology theft as well as trading.
- Bug fix: a non-zero 'techlevel' setting (or a ruleset which grants initial techs) along with certain 'plrcolormode' settings could give a (harmless) assertion failure at game start.
- Bug fix: a player observer can no longer cause the game to start on behalf of a player.
Changes affecting other rulesets / modders Edit
- Adding a base in the editor was not taking care of side-effects, such as removing conflicting bases on the same tile, granting vision and borders, etc.
- In the editor, the "Nation Start Positions" property could be disabled when changing other values on the Game tab of the property editor.
Changes affecting server operators Edit
- New 'persistent' metaserver connection mode, where one failure to talk to the metaserver does not prevent future attempts. Enabled with the '--keep' server option or the '/metaconnection persistent' server command.
- Minor memory leak fixes.
- Some optimizations for speed.
- Various internal changes which should only affect developers.
- AI players could occasionally be subject to the penalty for changing production type. They are supposed to always be immune to this penalty.
- It's now possible to create an all-AI game from the client, by becoming an observer and starting the game. (You also need to set 'minplayers' to 0 and set a turn timeout.)
- Fix drawing artifacts with oriented tilesets such as Cimpletoon:
- A unit could be drawn with two superimposed random orientations. This showed up in the Gtk unit select dialog and the Qt help.
- Unit orientation in these circumstances could change randomly on redraws.
- Fixes to disconnecting from servers and cleaning up spawned servers. In particular, the Gtk and Qt clients now disconnect cleanly from the server when you quit the client.
- For global observers, fixed display of city map outline and grid coloring.
- Fixed a potential buffer overflow in some clients in the presence of extremely long tileset or soundset names.
- (Gtk) Make Prev/Next City buttons insensitive for global observers, since they do nothing.
- (Gtk3) On very small screens, the balance between happiness and nationality areas in the city dialog has been improved.
- (Gtk3) Silence Gtk warnings on console by default with newer Gtk3 versions; this is necessary as it's not possible to construct a theme which works across the full range of Gtk3 versions we support without warnings. They can be re-enabled with freeciv-gtk3 -- --gtk-warnings.
- (Qt) Simplified the network page, so that local and Internet servers are on the same page. Scans for local servers are now stopped once a connection is chosen.
- (Qt) There's now a button to lock the messages and chat window geometry, so that a mis-click doesn't accidentally disarrange them.
- (Qt) The '5' key on the numeric keypad now selects the previous unit, as in the Gtk clients.
- (Qt) Allied chat (chat messages are sent only to allies, not all players) is now the default.
- (Qt) The default leader name defaults to the player name (often the system user name) rather than a leader name from a selected nation.
- (Qt) Added an option to change the theme.
- (Qt) The '<', '>', and '&' characters are now handled correctly in chat; they are no longer interpreted as HTML.
- (Qt) When there's a problem loading a tileset, an error message explaining it is now displayed.
- (SDL) The display of shields in the city dialog immediately after changing production could be overly pessimistic.
- Minor fix to freeciv-manual tool's output.
- Minor fix to modpack installer's error reporting.
Help / Documentation Edit
- The 'Chatline' help is now more comprehensive.
- The tutorial scenario now has a message for when you build your first military unit.
- Miscellaneous other improvements to in-game text and user documentation.
- Miscellaneous changes to developer/ruleset docs.
- Invisible changes to assist localization.
- Updated translations:
- Complete translations: Catalan, French, British English, Spanish, Russian.
- Incomplete translations: Finnish (100% core, 92% nations), Japanese (94% core, 95.4% nations).
- When localized into Finnish, the last character was stripped or corrupted in all messages.
- Package builders can now override the version label used with FREECIV_LABEL_FORCE.
- 'nonnull-compare' warnings from GCC 6 are now silenced.
- The included Lua now uses fseeko() instead of fseek() where available. This is unlikely to make a difference in practice.
- Update some of the libraries shipped with the Windows packages.
