# Mesa 8.0.3 Release Notes / May 18, 2012

Mesa 8.0.3 is a bug fix release which fixes bugs found since the 8.0.2 release.

Mesa 8.0.3 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 Compiling/Installing page for prerequisites for DRI hardware acceleration.
