It's been a slow year for GtkRadiant, but it's time to call it done for 1.6.4!
See the full release notes, and check the downloads for your operating system.
Thank you to Jay Dolan for his massive involvement in this release, bringing us MacOS X support as well as Quake 2 support. And thanks to all the testers on QuakeNet #radiant irc.
What's next you ask? We will probably scan through the issues list and build a hit list of things to look at for a 1.6.5 release.
