+<h1>Mesa 9.2.3 Release Notes / (November 13, 2013)</h1>
+
+<p>
+Mesa 9.2.3 is a bug fix release which fixes bugs found since the 9.2.2 release.
+</p>
+<p>
+Mesa 9.2 implements the OpenGL 3.1 API, but the version reported by
+glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
+glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 3.1.  OpenGL
+3.1 is <strong>only</strong> available if requested at context creation
+because GL_ARB_compatibility is not supported.
+</p>
