GtkRadiant has been updated to version 1.6.3
The main item for this release is the addition of QuakeLive support. This includes support for the encrypted paks, and png textures support (including on models). bspc.exe (for bot navigation files), and a version of q3map2 with QuakeLive support is provided as well.
The Urban Terror support has been improved as well. The default compiler for UrT is now the modified compiler that was release by FrozenSand, with the lighting model that UrT level designers are accustomed to.
The installers are available in the downloads section.
