are 14.2.2 (or later), are BlueStore, and (if they were created
prior to Nautilus) have been updated via the ``repair`` function.
* The default value for `mon_crush_min_required_version` has been
changed from `firefly` to `hammer`, which means the cluster will
issue a health warning if your CRUSH tunables are older than hammer.
There is generally a small (but non-zero) amount of data that will
move around by making the switch to hammer tunables; for more information,
see :ref:`crush-map-tunables`.
If possible, we recommend that you set the oldest allowed client to `hammer`
or later. You can tell what the current oldest allowed client is with::
ceph osd dump | grep min_compat_client
If the current value is older than hammer, you can tell whether it
is safe to make this change by verifying that there are no clients
older than hammer current connected to the cluster with::
ceph features
The newer `straw2` CRUSH bucket type was introduced in hammer, and
ensuring that all clients are hammer or newer allows new features
only supported for `straw2` buckets to be used, including the
`crush-compat` mode for the :ref:`balancer`.

* Ceph now packages python bindings for python3.6 instead of
python3.4, because EPEL7 recently switched from python3.4 to
python3.6 as the native python3. see the `announcement <https://lists.fedoraproject.org/archives/list/epel-announce@lists.fedoraproject.org/message/EGUMKAIMPK2UD5VSHXM53BH2MBDGDWMO/>`_
