+tdb improvements
+================
+
+The tdb library, our core mechanism to store Samba-specific data on disk and
+share it between processes, has been improved to support process shared robust
+mutexes on Linux. These mutexes are available on Linux and Solaris and
+significantly reduce the overhead involved with tdb. To enable mutexes for
+tdb, set
+
+dbwrap_tdb_mutexes:* = yes
+
+in the [global] section of your smb.conf.
+
+Tdb has furthermore improved to manage its file space more efficiently. This
+will lead to smaller and less fragmented databases.
+
+Messaging improvements
+======================
+
+Our internal messaging subsystem, used for example for things like oplock
+break messages between smbds or setting a process debug level dynamically, has
+been rewritten to use unix domain datagram messages.
