>=15.2.4
--------

* Cephadm: There were a lot of small usability improvements and bug fixes:

  * Grafana when deployed by Cephadm now binds to all network interfaces.
  * ``cephadm check-host`` now prints all detected problems at once.
  * Cephadm now calls ``ceph dashboard set-grafana-api-ssl-verify false``
    when generating an SSL certificate for Grafana.
  * The Alertmanager is now correctly pointed to the Ceph Dashboard
  * ``cephadm adopt`` now supports adopting an Alertmanager
  * ``ceph orch ps`` now supports filtering by service name
  * ``ceph orch host ls`` now marks hosts as offline, if they are not
    accessible.

* Cephadm can now deploy NFS Ganesha services. For example, to deploy NFS with
  a service id of mynfs, that will use the RADOS pool nfs-ganesha and namespace
  nfs-ns::

    ceph orch apply nfs mynfs nfs-ganesha nfs-ns

* Cephadm: ``ceph orch ls --export`` now returns all service specifications in
  yaml representation that is consumable by ``ceph orch apply``. In addition,
  the commands ``orch ps`` and ``orch ls`` now support ``--format yaml`` and
  ``--format json-pretty``.

* Cephadm: ``ceph orch apply osd`` supports a ``--preview`` flag that prints a preview of
  the OSD specification before deploying OSDs. This makes it possible to
  verify that the specification is correct, before applying it.

* RGW: The ``radosgw-admin`` sub-commands dealing with orphans --
  ``radosgw-admin orphans find``, ``radosgw-admin orphans find``,
  ``radosgw-admin orphans find`` -- have been deprecated. They have
  not been actively maintained and they store intermediate results on
  the cluster, which could fill a nearly-full cluster.  They have been
  replaced by a tool, currently considered experimental,
  ``rgw-orphan-list``.

* RBD: The name of the rbd pool object that is used to store
  rbd trash purge schedule is changed from "rbd_trash_trash_purge_schedule"
  to "rbd_trash_purge_schedule". Users that have already started using
  ``rbd trash purge schedule`` functionality and have per pool or namespace
  schedules configured should copy "rbd_trash_trash_purge_schedule"
  object to "rbd_trash_purge_schedule" before the upgrade and remove
  "rbd_trash_purge_schedule" using the following commands in every RBD
  pool and namespace where a trash purge schedule was previously
  configured::

    rados -p <pool-name> [-N namespace] cp rbd_trash_trash_purge_schedule rbd_trash_purge_schedule
    rados -p <pool-name> [-N namespace] rm rbd_trash_trash_purge_schedule

  or use any other convenient way to restore the schedule after the
  upgrade.
