# Mesa 7.6.1 Release Notes, 21 December 2009

Mesa 7.6.1 is a bug-fix release fixing issues since version 7.6.

Mesa 7.6.1 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.
