11 <H1>Mesa 7.8.2 Release Notes / (date tbd)</H1>
14 Mesa 7.8.2 is a bug fix release which fixes bugs found since the 7.8.1 release.
17 Mesa 7.8.2 implements the OpenGL 2.1 API, but the version reported by
18 glGetString(GL_VERSION) depends on the particular driver being used.
19 Some drivers don't support all the features required in OpenGL 2.1.
22 See the <a href="install.html">Compiling/Installing page</a> for prerequisites
23 for DRI hardware acceleration.
