+<H1>Mesa 8.0.3 Release Notes / May 18, 2012</H1>
+
+<p>
+Mesa 8.0.3 is a bug fix release which fixes bugs found since the 8.0.2 release.
+</p>
+<p>
+Mesa 8.0.3 implements the OpenGL 3.0 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 3.0.
+</p>
+<p>
+See the <a href="install.html">Compiling/Installing page</a> for prerequisites
+for DRI hardware acceleration.
+</p>

- * that uses duplicated vertices to render the disjoint strips as one
- * long strip. We'd have to be careful to avoid using too much memory
