+Mesa 12.0.1 Release Notes / July 8, 2016
+========================================
+
+Mesa 12.0.1 is a bug fix release which fixes bugs found since the 12.0.1
+release.
+
+Mesa 12.0.1 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.
