<h1>Mesa 7.4 Release Notes / 27 March 2009</h1>

<p>
Mesa 7.4 is a stable development release fixing bugs since the 7.3 release.
</p>
<p>
Mesa 7.4 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.
