For all you guys that have phpBB-based forums, such as this one, the newest update is now available to the public. It has a number of fixes, which I've listed below. I highlighted the stuff I found relatively important. The devs say that this is the last version of 2.0.x that will release, and the next version will be the updated, highly anticipated 2.2.
