It is mainly a bugfix release and includes improvements to the COLLADA 1.3 loader, support for Milkshape 1.8 files, enhanced .3ds, .obj loaders, Microsoft .x file animation playback improvements, added X11 support on OSX, several speed optimizations, and tons of bugfixes, API enhancements and other small improvements.
All the hard work has been done by the other team members (I've only done the release-stuff this time), so a big thanks go to them!
I'm also not that often here on the forum, but at least I gathered myself a bit and build you a new irrEdit version to be used with irrlicht 1.4.1, so happy downloading
