(svn r15045) -Add [NoAI API CHANGE]: in info.nut you can now have (optional) a CanLoadFromVersion(version), which should return true/false, to indicate if you can load a savegame made with your AI of version 'version'
-Add [NoAI API CHANGE]: in main.nut the Load() function now should be Load(version, data), where 'version' is the version of your AI which made the savegame -Codechange [NoAI]: various of function renames to make things more sane -Add [NoAI]: push the 'version' of the AI through various of layers -Codechange [NoAI]: various of code cleanups -Add [NoAI]: store the version of the AI in the savegame too
