->= 12.1.2
----------
-* When running 'df' on a CephFS filesystem comprising exactly one data pool,
- the result now reflects the file storage space used and available in that
- data pool (fuse client only).
-* Added new commands "pg force-recovery" and "pg-force-backfill". Use them
- to boost recovery or backfill priority of specified pgs, so they're
- recovered/backfilled before any other. Note that these commands don't
- interrupt ongoing recovery/backfill, but merely queue specified pgs
- before others so they're recovered/backfilled as soon as possible.
- New commands "pg cancel-force-recovery" and "pg cancel-force-backfill"
- restore default recovery/backfill priority of previously forced pgs.

-12.2.1
-------
-
-* Clusters will need to upgrade to 12.2.1 before upgrading to any
- Mimic 13.y.z version (either a development release or an eventual
- stable Mimic release).
-
-- *CephFS*:
-
- * Limiting MDS cache via a memory limit is now supported using the new
- mds_cache_memory_limit config option (1GB by default). A cache reservation
- can also be specified using mds_cache_reservation as a percentage of the
- limit (5% by default). Limits by inode count are still supported using
- mds_cache_size. Setting mds_cache_size to 0 (the default) disables the
- inode limit.
-
-* The maximum number of PGs per OSD before the monitor issues a
- warning has been reduced from 300 to 200 PGs. 200 is still twice
- the generally recommended target of 100 PGs per OSD. This limit can
- be adjusted via the ``mon_max_pg_per_osd`` option on the
- monitors. The older ``mon_pg_warn_max_per_osd`` option has been removed.
-
-* Creating pools or adjusting pg_num will now fail if the change would
- make the number of PGs per OSD exceed the configured
- ``mon_max_pg_per_osd`` limit. The option can be adjusted if it
- is really necessary to create a pool with more PGs.
