I have uploaded a setup for 1.3 on Linux x86 based on the work I did on setup this week end: http://www.3ddownloads.com/qeradiant/GtkRadiant/GtkRadiant-1_3/Linux/linux-radiant-1.3.5-dev.run That's not an official file. It's testing/experimental only. This is related to bug #750. Nethertheless it's the first packaging of a 1.3 release. TTimo
