 * The ``min_size`` and ``max_size`` CRUSH rule properties have been removed.  Older
   CRUSH maps will still compile but Ceph will issue a warning that these fields are
   ignored.
+* The cephadm NFS support has been simplified to no longer allow the
+  pool and namespace where configuration is stored to be customized.
+  As a result, the ``ceph orch apply nfs`` command no longer has
+  ``--pool`` or ``--namespace`` arguments.
+
+  Existing cephadm NFS deployments (from earlier version of Pacific or
+  from Octopus) will be automatically migrated when the cluster is
+  upgraded.  Note that the NFS ganesha daemons will be redeployed and
+  it is possible that their IPs will change.
