+<H1>Mesa 7.4.2 Release Notes / May 15, 2009</H1>
+
+<p>
+Mesa 7.4.2 is a stable development release fixing bugs since the 7.4.1 release.
+</p>
+<p>
+Mesa 7.4.2 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.
