7.9.1 release. 21</p> 22<p> 23Mesa 7.9.2 implements the OpenGL 2.1 API, but the version reported by 24glGetString(GL_VERSION) depends on the particular driver being used. 25Some drivers don't support all the features required in OpenGL 2.1. 26</p> 27<p> 28See the <a href="../install.html">Compiling/Installing page</a> for prerequisites 29for DRI hardware acceleration. 30</p> 31 32 33<h2>MD5
