While testing basxto's map editor, I notices that the map editor is versioned, and versioned differently than the game. The map editor shipped with MegaGlest 3.9.1 is versioned "1.6.1".
I think the map editor should not be versioned, or not versioned differently than the game itself, for as long as it is released as part of it. That's unless there is a good reason to do so, which I cannot currently think of.
What I think should be versioned is the map format. And once that's done the map editor should point out which map format versions it is compatible to.
I'd appreciate any developers' feedback on this.
