   4 Mesa 7.8.3 is a bug fix release which fixes bugs found since the 7.8.2
   5 release.
   6
   7 Mesa 7.8.3 implements the OpenGL 2.1 API, but the version reported by
   8 glGetString(GL_VERSION) depends on the particular driver being used.
   9 Some drivers don't support all the features required in OpenGL 2.1.
