I just uploaded Irrlicht version 1.5.1
to the sourceforge servers. This version contains a lot of bugfixes and corrections, but also some few new features: Support for range fog in OpenGL, improved X11 support, Better .x, STL and Collada file loading, terrain rendering using hw buffers and a lot of bug fixes and corrections.
Thanks to all people involved in this project, especially the irrlicht team
doing all the hard work. Always nice to have a new release out.
