Quake 3 mapbuilder GtkRadiant 1.6.4 has been released. Now there is support for Quake 2, Quake2World, OS X, thanks to Quake2World developer Jay Dolan. Support for RtCW, Star Trek Elite Force and Jedi Academy. The project has been updated to MS Visual Studio 2012. Thanks Happy Friar for the news.

In 2012 some developers decided to update the old official Quake 3 leveleditor GtkRadiant. For example TTimo, ex-id Software, is a member of the dev team. The version 1.6.2. from june 2012 was a mix between Radiant 202 and GTK 1.5. Some people said a few good functions from the original version 1.5 were deleted.
