19<p>
20Mesa 7.8.2 is a bug fix release which fixes bugs found since the 7.8.1 release.
21</p>
22<p>
23Mesa 7.8.2 implements the OpenGL 2.1 API, but the version reported by
24glGetString(GL_VERSION) depends on the particular driver being used.
25Some drivers don't support all the features required in OpenGL 2.1.
