Mesa 8.0.5 Release Notes / October 24, 2012
===========================================

Mesa 8.0.5 is a bug fix release which fixes bugs found since the 8.0.4
release.

Mesa 8.0.5 implements the OpenGL 3.0 API, but the version reported by
glGetString(GL_VERSION) depends on the particular driver being used.
Some drivers don't support all the features required in OpenGL 3.0.

See the :doc:`Compiling/Installing page <../install>` for
prerequisites for DRI hardware acceleration.
