  17 <h1>Mesa 17.2.7 Release Notes / December 14, 2017</h1>
  18
  19 <p>
  20 Mesa 17.2.7 is a bug fix release which fixes bugs found since the 17.2.6 release.
  21 </p>
  22 <p>
  23 Mesa 17.2.7 implements the OpenGL 4.5 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 4.5.  OpenGL
  27 4.5 is <strong>only</strong> available if requested at context creation
  28 because compatibility contexts are not supported.
