Version 0.7.7 of OpenArena is available. It was released as a patch to version 0.7.6 on 2008-05-29. Unfortunately, this version includes changes to the ioquake3 engine that make it incompatible with the current quake3 engine package. Most importantly, it reports engine version number 69 to prevent cross-version multiplayer.
As of today, the latest version is 0.8.1
