There are lots of little "annoying" bugs but we generally save patches for critical bugs. Things that cause your community to simply stop working, lose data, security, etc.
I know it might be annoying to come across those bugs but we are really happy people are finding those type of things and not complete-implosion issues :) Being that this is a x.0.0 release we honestly expected even more "big" issues than we have. Credit certainly goes to everyone that helped us test IPB in the beta and RC stages.
We think 3.0.1 will be out next week or early the week after. We didn't want to release it right before the July 4 holiday.
