Robert A. Duffy from ID Software updated his .plan file with following information:

The new Quake 3 Arena and Quake 3 Team Arena point release is up. Thanks to Timothee for getting all the fixes in and Tony and the crew at Even Balance for getting Punk Buster support in. A beta version of the Mac point release will be up soon but it will not authenticate properly with Punk Buster for a couple of weeks.

The release should be appearing on mirrors soon but here are the locations on our ftp. The auto-update system is also updated so you can auto-update or grab it here.
