+Mesa 10.6.3 Release Notes / July 26, 2015
+=========================================
+
+Mesa 10.6.3 is a bug fix release which fixes bugs found since the 10.6.2
+release.
+
+Mesa 10.6.3 implements the OpenGL 3.3 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
+3.3. OpenGL 3.3 is **only** available if requested at context creation
+because compatibility contexts are not supported.
