Digging around my SC2 folder, found that link.
Protoss got hit with the nerf hammer (Imo the gateway build time is too much... I think toss are gonna suck now).

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.
