+<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>
