7.9.1 Release Notes / January
7,
2011</H1>
16 Mesa
7.9.1 is a bug fix release which fixes bugs found since the
7.9 release.
19 Mesa
7.9.1 implements the OpenGL
2.1 API, but the version reported by
20 glGetString(GL_VERSION) depends on the particular driver being used.
21 Some drivers don't support all the features required in OpenGL
2.1.
24 See the
<a href=
"install.html">Compiling/Installing page
</a> for prerequisites
25 for DRI hardware acceleration.
