I have Version 3.0 (522.11) running on my MacBook Pro. Seems pretty stable.

There are a few new commands that I like: History/Reopen Last Closed Window; and History/Reopen All Windows from Last Session.

Some annoying new aspects is that the application is now more protective, querying you when you want to leave a page or shutdown. If you use something like OnePage, PageFlakes, or NetVibes, it warns you about losing data when you close a page (even though you won't and can't do anything about it anyway).
