As always, we strongly encourage all users to perform a full backup before performing any server maintenance. It may take longer, but you'll be better in the end.
Additionally, we've added a browser search extension for Firefox and IE. You can find it at the top of the Forum Home Page. When you add it, you can search the forums, wiki, blog, bugzilla, and documentation at once. This isn't a part of the 4.5.9 release.
