+CTDB changes
+------------
+
+* "ctdb event" is a new top-level command for interacting with event scripts
+
+  "ctdb event status" replaces "ctdb scriptstatus" - the latter is
+  maintained for backward compatibility but the output format has been
+  cleaned up
+
+  "ctdb event run" replaces "ctdb eventscript"
+
+  "ctdb event script enable" replaces "ctdb enablescript"
+
+  "ctdb event script disable" replaces "ctdb disablescript"
+
+  The new command "ctdb event script list" lists event scripts.
+
+* CTDB's back-end for running event scripts has been replaced by a
+  separate, long-running daemon ctdbd_eventd.
+
+* Running ctdb interactively will log to stderr
+
+* CTDB logs now include process id for each process
+
+* CTDB tags log messages differently.  Changes include:
+
+  ctdb-recoverd: Messages from CTDB's recovery daemon
+  ctdb-recovery: Messages from CTDB database recovery
+  ctdb-eventd: Messages from CTDB's event daemon
+  ctdb-takeover: Messgaes from CTDB's public IP takeover subsystem
+
+* The mapping between symbolic and numeric debug levels has changed
+
+  Configurations containing numeric debug levels should be updated.
+  Symbolic debug levels are recommended.  See the DEBUG LEVEL section
+  of ctdb(7) for details.
+
+*  Tunable IPAllocAlgorithm replaces LCP2PublicIPs, DeterministicIPs
+
+   See ctdb-tunables(7) for details
+
+* CTDB's configuration tunables should be consistently set across a cluster
+
+  This has always been the cases for most tunables but this fact is
+  now documented.
+
+* CTDB ships with recovery lock helper call-outs for etcd and Ceph RADOS
+
+  To build/install these, use the --enable-etcd-reclock and
+  --enable-ceph-reclock configure options.
