There are a few known ones, I would say "many bugs" is a bit exaggerated though. If you tell us which specific problems you're experiencing, maybe we can help. For quite some of the known bugs there already is a solution you can use right now before 3.1.11 is available.
and I'm just as sure that there will be bugs in the next release, and the next, and the one after that. How significant those bugs will be is another question.
