The Mesa 3D Graphics Library

# Mesa 13.0.0 Release Notes / November 1, 2016

Mesa 13.0.0 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 13.0.1.

Mesa 13.0.0 implements the OpenGL 4.4 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 4.4. OpenGL 4.4 is only available if requested at context creation because compatibility contexts are not supported.
