We just released Irrlicht version 1.6.1. This version contains a lot of bugfixes and corrections, like improvements with the GUI Environment, Lightmap rendering and DMF loading, and keyboard mapping under Linux.

On a related note, a new version of CopperCube has been released today as well, which now supports exporting scenes to .irr files. It also features a special property window to edit Irrlicht scene node properties and materials and can be used as world editor for Irrlicht.
