WHAT'S CHANGED SINCE 2.5.11
2.5.12 is a bugfix release. It is expected to be the final release in the 2.5 series.
Server / General
Changes affecting players (supplied rulesets)
- Vision-providing bases, such as buoys, could in some circumstances remove visibility from tiles, perhaps preventing the owner's cities from working them, in the presence of autosettlers.
- When a unit such as a Leader was cargo on a transport that was lost with its home city, it could be 'saved' by teleporting to the site of that city. This could leave an illegal stack of non-allied units on the same tile (Leader and city's conqueror), and prevent the Leader teleporting to a more distant, safe city.
- A few resources could be added to the map even when none were requested.
- Global warming and nuclear winter had a small chance of occurring even when the client displayed the chance as 0%.
- Cities produced pollution slightly too often.
- When gaining free Future Techs (for instance from Darwin's Voyage), some messages showed the wrong Future Tech number.
- Historians were never reporting on the "LARGEST Civilizations" (with the most citizens), by mistake.
- Historians failed to take angry citizens into account when reporting on the "HAPPIEST Civilizations".
- The end-game score for an arrived spaceship included population in habitation modules that weren't actually attached to the spaceship at launch.
- Fix a possible network protocol warning when units are starving.
Changes affecting other rulesets / modders
- In rulesets which allow capturing units, it's no longer allowed to capture a transport which is carrying units. (Previously this was allowed, but left the game in a broken state.)
- Fix longstanding bug in rulesets with 129 or more unit types; if any of the later units was an upgrade or conversion target, the client would not allow the action.
- In rulesets with nation-specific starting units, care is now taken to place them on tiles they can exist on, and clear any huts from their tile.
- Rulesets which defined a unit type without any tech_req could crash the server, rather than giving an error message.
- Rulesets which used default/nationlist.ruleset could not define a default_government outside the standard set defined by nationlist.ruleset.
- Fix inability to use default/nationlist.ruleset in a custom ruleset lacking standard plural-named terrains such as 'Hills'.
- Some improvements to unit debugging (/debug unit).
- Coding style clean up to supplied default.lua script.
- Fix a rare compression failure which could stop communication between client and server.
- Slightly improved diagnostics for missing sound files.
- Tweak format of comments in various output files.
- Various internal changes which should only affect developers.
- When setting up single-player games, the client's AI level control no longer gets out of sync with the server state.
- In the city dialog, clicking on the middle tile to rearrange workers could fail to update the city dialog map display.
- (Gtk3) If you pressed Escape when prompted for the name of a new city, the relevant unit could subsequently not respond to the (B)uild City command at all. Hitting Escape when renaming a city could also lead to trouble.
- (Gtk3) Happiness tooltips from the city dialog could appear in the wrong place.
- (SDL) Fix a possible crash on closing the client.
