Go ahead and read their changelogs, if you don't see anything like "fixed CTD" or "fixed crash to desktop" or "fixed broken save" then it means the previous version is just as safe as the newest one, but maybe small glitches may have gotten fixed which may improve the gameplay, or you may not even notice them. At this point in time I believe the game is pretty much stable, but haven't played for a while nor checked the change logs myself.Should i download this version (2.09) or wait? seems like there's more version in this last thread.
