* librbd: The shared, read-only parent cache's config option ``immutable_object_cache_watermark`` now has been updated
to property reflect the upper cache utilization before space is reclaimed. The default ``immutable_object_cache_watermark``
now is ``0.9``. If the capacity reaches 90% the daemon will delete cold cache.
+ * The ceph_volume_client.py library used for manipulating legacy "volumes" in
+ CephFS is removed. All remaining users should use the "fs volume" interface
+ exposed by the ceph-mgr:
+ https://docs.ceph.com/en/latest/cephfs/fs-volumes/
+
+ * An AWS-compliant API: "GetTopicAttributes" was added to replace the existing
+ "GetTopic" API. The new API should be used to fetch information about topics
+ used for bucket notifications.

+ * OSD: the option ``osd_fast_shutdown_notify_mon`` has been introduced to allow
+ the OSD to notify the monitor it is shutting down even if ``osd_fast_shutdown``
+ is enabled. This helps with the monitor logs on larger clusters, that may get
+ many 'osd.X reported immediately failed by osd.Y' messages, and confuse tools.
+ * rgw/kms/vault: the transit logic has been revamped to better use
+ the transit engine in vault. To take advantage of this new
+ functionality configuration changes are required. See the current
+ documentation (radosgw/vault) for more details.
+* Scubs are more aggressive in trying to find more simultaneous possible PGs within osd_max_scrubs limitation.
+ It is possible that increasing osd_scrub_sleep may be necessary to maintain client responsiveness.
