  17. <h1>Mesa 9.0 Release Notes / October 8, 2012</h1>
  18.  
  19. <p>
  20. Mesa 9.0 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 9.0.1.
  23. </p>
  24. <p>
  25. Mesa 9.0 implements the OpenGL 3.1 API, but the version reported by
  26. glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  27. glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
  28. Some drivers don't support all the features required in OpenGL 3.1.  OpenGL
  29. 3.1 is <strong>only</strong> available if requested at context creation
  30. because GL_ARB_compatibility is not supported.
