<h1>Mesa 7.9.2 Release Notes / March 2, 2011</h1>
<p>
Mesa 7.9.2 is a bug fix release which fixes bugs found since the 7.9.1 release.
</p>
<p>
Mesa 7.9.2 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.
</p>
<p>
See the <a href="../install.html">Compiling/Installing page</a> for prerequisites
for DRI hardware acceleration.
</p>
