If you're creating a new thread or viewing a forum, you'll notice a new feature called Thread Prefixes. A thread prefix is an optional tag displayed before the thread title to help categorize the post. For example, you can now set the thread prefix to "Bug" or "How to?", and moderators can (re)set the prefix to "Fixed" or "WAD". We'll be adding some more prefixes soon; if you have any requests please let us know.
