Auto Tap is now smarter! It will now apply more logic when choosing whether or not to tap a creature for mana (it shouldn't be so fond of an adapted Incubation Druid, for example).
Really hope it'll stop saving [[Unclaimed territory]] for last now.
EDIT : Just played against sparky, I had a spell breaker, a lava coil and 5 land in play and it didn't touch my unclaimed territory to cast the spell breaker.
