  17. <h1>Mesa 7.11.1 Release Notes / November 17, 2011</h1>
  18.  
  19. <p>
  20. Mesa 7.11.1 is a bug fix release which fixes bugs found since the 7.11 release.
  21. </p>
  22. <p>
  23. Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by
  24. glGetString(GL_VERSION) depends on the particular driver being used.
  25. Some drivers don't support all the features required in OpenGL 2.1.
  26. </p>
  27. <p>
  28. See the <a href="../install.html">Compiling/Installing page</a> for prerequisites
  29. for DRI hardware acceleration.
