   1 Mesa 7.9 Release Notes / October 4, 2010
   2 ========================================
   3
   4 Mesa 7.9 is a new development release. People who are concerned with
   5 stability and reliability should stick with a previous release or wait
   6 for Mesa 7.9.1.
   7
   8 Mesa 7.9 implements the OpenGL 2.1 API, but the version reported by
   9 glGetString(GL_VERSION) depends on the particular driver being used.
  10 Some drivers don't support all the features required in OpenGL 2.1.
  11
  12 See the :doc:`Compiling/Installing page <../install>` for
  13 prerequisites for DRI hardware acceleration.
