Mesa 7.8.3 Release Notes / (date tbd)
=====================================

Mesa 7.8.3 is a bug fix release which fixes bugs found since the 7.8.2
release.

Mesa 7.8.3 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.
