Mesa 7.8.2 Release Notes / June 17, 2010
========================================

Mesa 7.8.2 is a bug fix release which fixes bugs found since the 7.8.1
release.

Mesa 7.8.2 implements the OpenGL 2.1 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 2.1.

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