+Version 1.41
+------------
+Fix NTLMv2 security (can be enabled in /proc/fs/cifs) so customers can
+configure stronger authentication. Fix sfu symlinks so they can
+be followed (not just recognized).
+
Version 1.40
------------
Use fsuid (fsgid) more consistently instead of uid (gid). Improve performance
