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 Compiling/Installing page for prerequisites for DRI hardware acceleration.
