# Mesa 7.3 Release Notes / 22 January 2009

Mesa 7.3 is a new development release. Users especially concerned with stability should stick with latest stable release: version 7.2.

Mesa 7.3 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.
