+<H1>Mesa 7.6 Release Notes / date TBD</H1>
+
+<p>
+Mesa 7.6 is a new development release.
+People who are concerned with stability and reliability should stick
+with a previous release or wait for Mesa 7.6.1.
+</p>
+<p>
+Mesa 7.6 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.
