Merlijn Hofstra was the Xonotic game developer talking in Brussels this weekend. In his presentation he shared that Xonotic v0.6 is nearly here,
Xonotic 0.6 is considered fully stable while bringing lots of new features and being their last step before the 1.0 release. There's now a stats-tracking system, a new menu system, "Sandbox" support for freely moving/editing objects, and tons of in-game enhancements. One of the other improvements over Nexuiz is that Xonotic has support for fully-interactive vehicles, but some of that is still considered a work-in-progress and there's a need for new, larger maps to fully take advantage of the vehicle transportation.
