------
-* The following OSD memory config options related to bluestore cache autotuning can now
- be configured during runtime:
-
- - osd_memory_base (default: 768 MB)
- - osd_memory_cache_min (default: 128 MB)
- - osd_memory_expected_fragmentation (default: 0.15)
- - osd_memory_target (default: 4 GB)
-
- The above options can be set with::
-
- ceph config set global <option> <value>
-
-* The MGR now accepts 'profile rbd' and 'profile rbd-read-only' user caps.
- These caps can be used to provide users access to MGR-based RBD functionality
- such as 'rbd perf image iostat' an 'rbd perf image iotop'.
-
-* The configuration value ``osd_calc_pg_upmaps_max_stddev`` used for upmap
- balancing has been removed. Instead use the mgr balancer config
- ``upmap_max_deviation`` which now is an integer number of PGs of deviation
- from the target PGs per OSD. This can be set with a command like
- ``ceph config set mgr mgr/balancer/upmap_max_deviation 2``. The default
- ``upmap_max_deviation`` is 1. There are situations where crush rules
- would not allow a pool to ever have completely balanced PGs. For example, if
- crush requires 1 replica on each of 3 racks, but there are fewer OSDs in 1 of
- the racks. In those cases, the configuration value can be increased.
-
-* RGW: a mismatch between the bucket notification documentation and the actual
- message format was fixed. This means that any endpoints receiving bucket
- notification, will now receive the same notifications inside an JSON array
- named 'Records'. Note that this does not affect pulling bucket notification
- from a subscription in a 'pubsub' zone, as these are already wrapped inside
- that array.
-
-* Ceph will now issue a health warning if a RADOS pool as a ``pg_num``
- value that is not a power of two. This can be fixed by adjusting
- the pool to a nearby power of two::
-
- ceph osd pool set <pool-name> pg_num <new-pg-num>
-
- Alternatively, the warning can be silenced with::
-
- ceph config set global mon_warn_on_pool_pg_num_not_power_of_two false
-
-* Bucket notifications now support Kafka endpoints. This require librdkafka of version 0.9.2 and up.
- Note that Ubuntu 16.04.6 LTS (Xenial Xerus) has an older version of librdkafka, and would
- require an update to the library.
