# Mesa 7.8.1 Release Notes / April 5, 2010

Mesa 7.8.1 fixes a couple critical bugs in the recent Mesa 7.8 release. Even though this is a bug fix release, given its proximity to the 7.8 release, a new development release, it should also be considered new development release. People who are concerned with stability and reliability should stick with a previous release, such as 7.7.1, or wait for Mesa 7.8.2.

Mesa 7.8.1 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.
