Nethaera has posted the official "patch notes" for patch 188.8.131.5206/3.0.8a today. They are listed in their entirety after the break.
These notes mirror what Ghostcrawler said in a series of posts last night. I imagine that these patch notes could be updated at some future time, listing more bug fixes if they're present. So you'll probably want to check back later and see if that's the case.
