+<h1>Mesa 13.1.0 Release Notes / TBD</h1>
+
+<p>
+Mesa 13.1.0 is a new development release.
+People who are concerned with stability and reliability should stick
+with a previous release or wait for Mesa 13.1.1.
+</p>
+<p>
+Mesa 13.1.0 implements the OpenGL 4.4 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 4.4.  OpenGL
+4.4 is <strong>only</strong> available if requested at context creation
+because compatibility contexts are not supported.
+</p>
