According to the changelog there haven't been any substantial bugfixes/improvements to the game, at least nothing I can see to fix the more prevalent issues such as node corruption on turrets and AI pathfinding.

So really not much point patching past 1.40 right?

Also the crash related to corpse furnace usage, was that ever fixed? I also get a crash when picking up Holy nation units that are playing dead. Not outlaws but the Paladins. Both seem related to physics errors.
