<h1>Mesa 8.0.4 Release Notes / July 10, 2012</h1>
<p>
Mesa 8.0.4 is a bug fix release which fixes bugs found since the 8.0.2 release.
</p>
<p>
Mesa 8.0.4 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.
