7.11.1 Release Notes / November
17,
2011</h1>
20 Mesa
7.11.1 is a bug fix release which fixes bugs found since the
7.11 release.
23 Mesa
7.11 implements the OpenGL
2.1 API, but the version reported by
24 glGetString(GL_VERSION) depends on the particular driver being used.
25 Some drivers don't support all the features required in OpenGL
2.1.
28 See the
<a href=
"../install.html">Compiling/Installing page
</a> for prerequisites
29 for DRI hardware acceleration.
