There's an additional list of in-game fixes released tonight by Bornakk. The fixes have been coming less and less over the past week, and that's reflected in the fact the game's stability has vastly improved since patch 3.1 dropped (at least for most).
We covered some of the Ulduar changes, which were announced separately this evening. Apparently Blizzard felt them important enough to mix them in with these other changes as well.
Chief amongst the changes is that the Tier 8 4 piece set bonus for Druids now works. I don't honestly know anyone that has ran into this yet, but I'm sure there's a few folks out there with four pieces of Tier 8 already.
The entire list of changes after the break.
