  17. <h1>Mesa 7.9 Release Notes / October 4, 2010</h1>
  18.  
  19. <p>
  20. Mesa 7.9 is a new development release.
  21. People who are concerned with stability and reliability should stick
  22. with a previous release or wait for Mesa 7.9.1.
  23. </p>
  24. <p>
  25. Mesa 7.9 implements the OpenGL 2.1 API, but the version reported by
  26. glGetString(GL_VERSION) depends on the particular driver being used.
  27. Some drivers don't support all the features required in OpenGL 2.1.
  28. </p>
  29. <p>
  30. See the <a href="../install.html">Compiling/Installing page</a> for prerequisites
  31. for DRI hardware acceleration.
