The .tilespec fileEdit

• Set tilespec format of every file to options = "+Freeciv-tilespec-Devel-YYYY.MMM.DD" during development. For freeciv 2.4 option = "+Freeciv-2.4-tilespec" should be used.

GeneralEdit

• The definition of the player colors in the file colors.tilespec is merge with the data in colors.spec / colors.png and saved in game.ruleset. See also How to update a ruleset from 2.3 to 2.4.

FeaturesEdit

The .spec filesEdit

• Set spec format format of every file to options = "+Freeciv-spec-Devel-YYYY.MMM.DD" during development. For freeciv 2.4 option = "+Freeciv-2.4-spec" should be used.

GeneralEdit

• The definition of the city images uses a simple, increasing number which is selected via an effect (City_Image). Thus, city.*_0, city.*_8, city.*_12 ... should be changed to city.*_0, city.*_1, city.*_2 ... (The relationship between city size, and possibly other properties, and these images is now defined by rulesets; see How to update a ruleset from 2.3 to 2.4)

• The file colors.spec is removed. The colors are defined in the terrain.ruleset file (terrain colors) or in game.ruleset (player colors). See also How to update a ruleset from 2.3 to 2.4.
