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