We don't publish a comprehensive list of every bug and issue fixed in each release. We do, however, go through the support topics here and make note of the issues that we've addressed and features that we've implemented so that customers are aware. If you have a particular bug/issue that you've previously reported, we would likely have posted to it if it was fixed.
If you have any outstanding bugs that are still bothering you, you're welcome to post to those topics to bring them back to our attention.
When you block a person, they can no longer invite you to a private message or post to your profile wall. Replies and comments they make will be collapsed/hidden by default. Finally, you'll never receive email notifications about content they create or likes they designate for your content.
