Mesa 7.4 Release Notes / 27 March 2009
======================================

Mesa 7.4 is a stable development release fixing bugs since the 7.3
release.

Mesa 7.4 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.
