+Mesa 7.9.1 Release Notes / January 7, 2011
+
+
+Mesa 7.9.1 is a bug fix release which fixes bugs found since the 7.9 release.
+
+
+Mesa 7.9.1 implements the OpenGL 2.1 API, but the version reported by
+glGetString(GL_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 2.1.
+
+
+See the Compiling/Installing page for prerequisites
+for DRI hardware acceleration.
