The two most important feature additions are a stats tracking system, which can be found via this webpage.
And the addition of client side scripted player-models, which probably doesn't say much to the regular user, but from a developer's point of view it is a pretty great thing ;) Expect many cool advances to come from this over the next couple of months.
Oh and try also the Overkill server, which runs a cool mod with totally new player-models and weapon mechanics, combining insta-gib with a more complex game-play etc. (in Xonotic, server admins can decide to hosts mods and players are automatically supplied with all needed files when joining the server).
Let's hope this new release will increase the player-base a bit, as this game really deserves more attention.
