-  * dynamic resharding is now enabled by default, RGW will now automatically
-  reshard the bucket index once the index grows beyond `rgw_max_objs_per_shard`

-- *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.
-
-* There was a bug in the PG mapping behavior of the new *upmap*
-  feature. If you made use of this feature (e.g., via the `ceph osd
-  pg-upmap-items` command), we recommend that all mappings be removed (via
-  the `ceph osd rm-pg-upmap-items` command) before upgrading to this
-  point release.
