+Mesa 9.1 Release Notes / February 22, 2013
+==========================================
+
+Mesa 9.1 is a new development release. People who are concerned with
+stability and reliability should stick with a previous release or wait
+for Mesa 9.1.1.
+
+Mesa 9.1 implements the OpenGL 3.1 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
+3.1. OpenGL 3.1 is **only** available if requested at context creation
+because GL_ARB_compatibility is not supported.
