   1 Mesa 11.1.0 Release Notes / 15 December 2015
   2 ============================================
   3
   4 Mesa 11.1.0 is a new development release. People who are concerned with
   5 stability and reliability should stick with a previous release or wait
   6 for Mesa 11.1.1.
   7
   8 Mesa 11.1.0 implements the OpenGL 4.1 API, but the version reported by
   9 glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
  10 glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
  11 used. Some drivers don't support all the features required in OpenGL
  12 4.1. OpenGL 4.1 is **only** available if requested at context creation
  13 because compatibility contexts are not supported.
