 * Added new configuration "public bind addr" to support dynamic environments
   like Kubernetes. When set the Ceph MON daemon could bind locally to an IP
   address and advertise a different IP address "public addr" on the network.
+* RGW: bucket index resharding now uses the reshard namespace in upgrade scenarios as well
+  this is a changed behaviour from RC1 where a new pool for reshard was created

 * The "ceph -w" output no longer contains audit log entries by default.
   Add a "--watch-channel=audit" or "--watch-channel=*" to see them.

+* New "ceph -w" behavior - the "ceph -w" output no longer contains I/O rates,
+  available space, pg info, etc. because these are no longer logged to the
+  central log (which is what "ceph -w" shows). The same information can be
+  obtained by running "ceph pg stat"; alternatively, I/O rates per pool can
+  be determined using "ceph osd pool stats". Although these commands do not
+  self-update like "ceph -w" did, they do have the ability to return formatted
+  output by providing a "--format=<format>" option.
+
+* Pools are now expected to be associated with the application using them.
+  Upon completing the upgrade to Luminous, the cluster will attempt to associate
+  existing pools to known applications (i.e. CephFS, RBD, and RGW). In-use pools
+  that are not associated to an application will generate a health warning. Any
+  unassociated pools can be manually associated using the new
+  "ceph osd pool application enable" command. For more details see
+  "Associate Pool to Application" in the documentation.
+
+* ceph-mgr now has a Zabbix plugin. Using zabbix_sender it sends trapper
+  events to a Zabbix server containing high-level information of the Ceph
+  cluster. This makes it easy to monitor a Ceph cluster's status and send
+  out notifications in case of a malfunction.
+
+* The 'mon_warn_osd_usage_min_max_delta' config option has been
+  removed and the associated health warning has been disabled because
+  it does not address clusters undergoing recovery or CRUSH rules that do
+  not target all devices in the cluster.
+
+* Specifying user authorization capabilities for RBD clients has been
+  simplified. The general syntax for using RBD capability profiles is
+  "mon 'profile rbd' osd 'profile rbd[-read-only][ pool={pool-name}[, ...]]'".
+  For more details see "User Management" in the documentation.
+
+* ``ceph config-key put`` has been deprecated in favor of ``ceph config-key set``.
