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.
