     10 <h1>Mesa 7.4 Release Notes / 27 March 2009</h1>
     11 
     12 <p>
     13 Mesa 7.4 is a stable development release fixing bugs since the 7.3 release.
     14 </p>
     15 <p>
     16 Mesa 7.4 implements the OpenGL 2.1 API, but the version reported by
     17 glGetString(GL_VERSION) depends on the particular driver being used.
     18 Some drivers don't support all the features required in OpenGL 2.1.
     19 </p>
     20 <p>
     21 See the <a href="install.html">Compiling/Installing page</a> for prerequisites
     22 for DRI hardware acceleration.
