2========================================
3
4Mesa 7.9.2 is a bug fix release which fixes bugs found since the 7.9.1
5release.
6
7Mesa 7.9.2 implements the OpenGL 2.1 API, but the version reported by
8glGetString(GL_VERSION) depends on the particular driver being used.
9Some drivers don't support all the features required in OpenGL 2.1.
