* New OSD daemon command dump_scrub_reservations which reveals the
scrub reservations that are held for local (primary) and remote (replica) PGs.
* The ``pg_autoscale_mode`` is now set to ``on`` by default for newly
created pools, which means that Ceph will automatically manage the
number of PGs. To change this behavior, or to learn more about PG
autoscaling, see :ref:`pg-autoscaler`. Note that existing pools in
upgraded clusters will still be set to ``warn`` by default.
