   1 Mesa 7.9.2 Release Notes / March 2, 2011
   2 ========================================
   3
   4 Mesa 7.9.2 is a bug fix release which fixes bugs found since the 7.9.1
   5 release.
   6
   7 Mesa 7.9.2 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.
  10
  11 See the :doc:`Compiling/Installing page <../install>` for
  12 prerequisites for DRI hardware acceleration.
