+The GNU automake/autoconf support has been removed.  As it was, it seldom
+worked on anything but Linux.  The Mesa developers aren't big fans of
+automake/autoconf and didn't have the time to maintain it.  If someone
+wants to contribute new automake/autoconf support (and is willing to

+Directory tree reorganization
+-----------------------------
+
+The directory structure for Mesa has been overhauled to improve its layout.
+All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
+in appropriate subdirectories.
+
+The Mesa source code and drivers has been reorganized under src/mesa/.
