  17. <h1>Mesa 9.0.3 Release Notes / February 21th, 2013</h1>
  18.  
  19. <p>
  20. Mesa 9.0.3 is a bug fix release which fixes bugs found since the 9.0.2 release.
  21. </p>
  22. <p>
  23. Mesa 9.0 implements the OpenGL 3.1 API, but the version reported by
  24. glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  25. glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used.
  26. Some drivers don't support all the features required in OpenGL 3.1.  OpenGL
  27. 3.1 is <strong>only</strong> available if requested at context creation
  28. because GL_ARB_compatibility is not supported.
