  13 <H1>Mesa 7.11.1 Release Notes / November 17, 2011</H1>
  14
  15 <p>
  16 Mesa 7.11.1 is a bug fix release which fixes bugs found since the 7.11 release.
  17 </p>
  18 <p>
  19 Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by
  20 glGetString(GL_VERSION) depends on the particular driver being used.
  21 Some drivers don't support all the features required in OpenGL 2.1.
  22 </p>
  23 <p>
  24 See the <a href="install.html">Compiling/Installing page</a> for prerequisites
  25 for DRI hardware acceleration.
