Mesa 12.0.6 Release Notes / January 23, 2017
============================================

Mesa 12.0.6 is a bug fix release which fixes bugs found since the 12.0.5
release.

Mesa 12.0.6 implements the OpenGL 4.3 API, but the version reported by
glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) /
glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being
used. Some drivers don't support all the features required in OpenGL
4.3. OpenGL 4.3 is **only** available if requested at context creation
because compatibility contexts are not supported.
