   1 Mesa 17.2.7 Release Notes / December 14, 2017
   2 =============================================
   3
   4 Mesa 17.2.7 is a bug fix release which fixes bugs found since the 17.2.6
   5 release.
   6
   7 Mesa 17.2.7 implements the OpenGL 4.5 API, but the version reported by
   8 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
   9 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
  10 used. Some drivers don't support all the features required in OpenGL
  11 4.5. OpenGL 4.5 is **only** available if requested at context creation
  12 because compatibility contexts are not supported.
