+CTDB changes
+------------
+
+* When Samba is configured with both --with-cluster-support and
+  --systemd-install-services then a systemd service file for CTDB will
+  be installed.
+
+* ctdbd_wrapper has been removed.  ctdbd is now started directly from
+  a systemd service file or init script.
+
+* The syntax for the ctdb.tunables configuration file has been
+  relaxed.  However, trailing garbage after the value, including
+  comments, is no longer permitted.  Please see ctdb-tunables(7) for
+  more details.
