v3 changed much of the file structure. it will be incompatible to v3PR mods, but adaption should not be to difficult. all new features we introduced will be available for moder of v3, too, of course

Actually, an interesting feature I thought would be neat to have would be an auto-updater. I suppose you don't REALLY need one, since the game doesn't get updated once a week, but I still thought it'd be neat. That way instead of people trying to find exactly which patch is the right one and stuff like that, the game would auto-update. What do you think?
