It seems that balance changes were minor, but only regarding one race. We feel that Protoss is a bit nerfed, especially building radius for Colossus that is so often used in all three matchups. Also, mothership seems to be nerfed too - no more Wormhole Transit or Temporal Rift - instead we get Arbiter-like "Mass Recall" spell.
Terrans got pretty fair balances, not nerfed too much and not too powered either. Orbital command now needs less time to be upgraded from basic Command Center, Viking gone trough some minor changes and Reaper now deals less damage.
Notoriously imbalanced Zerg didn't change too much which is somewhat sad. Infestor's Fungal Growth ability has suffered some not so big changes and that's about it for Zerg. We strongly belive that Blizzard will for sure get take care of this race in another set of patches.

BUG FIXES
* Addressed an issue causing people to receive an “Internal Battle.net Error” message with their game client.
* Muting your microphone will no longer cause your microphone to be turned off in the operating system once the program has exited.
o Please note that the voice chat functionality has only partially been implemented. There are many known issues with voice chat that we expect to address in a future patch.
* The “Medium” graphical settings were reconfigured to work better on appropriate machines. The video settings “auto-detect” functionality has been reset as a result.
* Added a frame rate limiter to the game menus to prevent some graphics cards from running at higher frame rates than necessary.
