With the 1.27g privately released for mod makers, there have been a number of mod re-releases, and there will be more. The latest one is the Coliseum2 mod, which is like Lithium for Quake2. Over the weekend we had QBind, OSP Tourney and Reqieum. The Alliance CTF website has a new movie showing off new features from the 2.0 version that's coming out soon, compatible with 1.27g as well.
If you still need 1.17 for some servers and so you aren't using 1.27 yet, this program allows you to switch between the two. And lastly a mod that isn't yet but there are new pictures, Quake3 Rally featured on extreme-players.de.
