We're happy to announce the 8th backport release in the Octopus series. This release
fixes a security flaw in CephFS and includes a number of bug fixes. We recommend users to
update to this release. For a detailed release notes with links & changelog please

Notable Changes
---------------
* CVE-2020-27781 : OpenStack Manila use of ceph_volume_client.py library allowed
tenant access to any Ceph credential's secret. (Kotresh Hiremath Ravishankar,
Ramana Raja)
* ceph-volume: The `lvm batch` subcommand received a major rewrite. This closed
a number of bugs and improves usability in terms of size specification and
calculation, as well as idempotency behaviour and disk replacement process.
Please refer to
https://docs.ceph.com/en/latest/ceph-volume/lvm/batch/ for
more detailed information.
* MON: The cluster log now logs health detail every `mon_health_to_clog_interval`,
which has been changed from 1hr to 10min. Logging of health detail will be
skipped if there is no change in health summary since last known.
* The `ceph df` command now lists the number of pgs in each pool.
* The `bluefs_preextend_wal_files` option has been removed.
* It is now possible to specify the initial monitor to contact for Ceph tools
and daemons using the `mon_host_override` config option or
`--mon-host-override <ip>` command-line switch. This generally should only
be used for debugging and only affects initial communication with Ceph's
monitor cluster.
