SGI has announced today announced the release of a new version of the SGI Free Software License B. This software license is now nearly identical to the X11 license in use by X.Org. The GLX API and other GLX extensions are now casted under this revised SGI license. Most importantly, the Free Software Foundation approves this relicensing and they have also received praise from the Khronos Group, the company behind OpenGL. The press release in full can be read at the
SGI web-site. This license is more "free", which is good news for the X.Org and Mesa communities.
