+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Please see `Upgrading from Bobtail to Cuttlefish`_ for details.
+
+.. _Upgrading from Bobtail to Cuttlefish: ../install/upgrading-ceph/#upgrading-from-bobtail-to-cuttlefish
+
+* radosgw-admin now uses the term zone instead of cluster to describe
+ each instance of the radosgw data store (and corresponding
+ collection of radosgw daemons). The usage for the radosgw-admin
+ command and the 'rgw zone root pool' config optoins have changed
+ accordingly.
+
+* rbd progress indicators now go to standard error instead of standard
+ out. (You can disable progress with --no-progress.)
+
+* The 'rbd resize ...' command now requires the --allow-shrink option
+ when resizing to a smaller size. Expanding images to a larger size
+ is unchanged.
+
+* Please review the changes going back to 0.56.4 if you are upgrading
+ all the way from bobtail.
+
+* The old 'ceph stop_cluster' command has been removed.
+
+* The sysvinit script now uses the ceph.conf file on the remote host
+ when starting remote daemons via the '-a' option. Note that if '-a'
+ is used in conjuction with '-c path', the path must also be present
+ on the remote host (it is not copied to a temporary file, as it was
+ previously).
+
+* The monitor is using a completely new storage strategy and
+ intra-cluster protocol. This means that cuttlefish and bobtail
+ monitors do not talk to each other. When you upgrade each one, it
+ will convert its local data store to the new format. Once you
+ upgrade a majority, the quorum will be formed using the new protocol
+ and the old monitors will be blocked out until they too get
+ upgraded. For this reason, we recommend not running a mixed-version
+ cluster for very long.
+
+* ceph-mon now requires the creation of its data directory prior to
+ --mkfs, similarly to what happens on ceph-osd. This directory is no
+ longer automatically created, and custom scripts should be adjusted to
+ reflect just that.
+
+* The monitor now enforces that MDS names be unique. If you have
+ multiple daemons start with with the same id (e.g., ``mds.a``) the
+ second one will implicitly mark the first as failed. This makes
+ things less confusing and makes a daemon restart faster (we no
+ longer wait for the stopped daemon to time out) but existing
+ multi-mds configurations may need to be adjusted accordingly to give
+ daemons unique names.
+
+* The 'ceph osd pool delete <poolname>' and 'rados rmpool <poolname>'
+ now have safety interlocks with loud warnings that make you confirm
+ pool removal. Any scripts curenty rely on these functions zapping
+ data without confirmation need to be adjusted accordingly.
+
