4* ceph-volume: The ``lvm batch` subcommand received a major rewrite. This closed
5 a number of bugs and improves usability in terms of size specification and
6 calculation, as well as idempotency behaviour and disk replacement process.
7 Please refer to https://docs.ceph.com/en/latest/ceph-volume/lvm/batch/ for
8 more detailed information.

10* MON: The cluster log now logs health detail every ``mon_health_to_clog_interval``,
11 which has been changed from 1hr to 10min. Logging of health detail will be
12 skipped if there is no change in health summary since last known.

14* The ``ceph df`` command now lists the number of pgs in each pool.

16* The ``bluefs_preextend_wal_files`` option has been removed.
17
18* It is now possible to specify the initial monitor to contact for Ceph tools
19 and daemons using the ``mon_host_override`` config option or
20 ``--mon-host-override <ip>`` command-line switch. This generally should only
21 be used for debugging and only affects initial communication with Ceph's
22 monitor cluster.
