Any special action for upgrading from 13.2.1 ?

Objet: v13.2.4 Mimic released

This is the fourth bugfix release of the Mimic v13.2.x long term stable 
release series. This release includes two security fixes atop of v13.2.3 
We recommend all users upgrade to this version. If you've already 
upgraded to v13.2.3, the same restrictions from v13.2.2->v13.2.3 apply 
here as well. 

Notable Changes 
--------------- 

* CVE-2018-16846: rgw: enforce bounds on max-keys/max-uploads/max-parts (`issue#35994 <http://tracker.ceph.com/issues/35994>`_) 
* CVE-2018-14662: mon: limit caps allowed to access the config store 

Notable Changes in v13.2.3 
--------------------------- 

* The default memory utilization for the mons has been increased 
somewhat. Rocksdb now uses 512 MB of RAM by default, which should 
be sufficient for small to medium-sized clusters; large clusters 
should tune this up. Also, the `mon_osd_cache_size` has been 
increase from 10 OSDMaps to 500, which will translate to an 
additional 500 MB to 1 GB of RAM for large clusters, and much less 
for small clusters. 

* Ceph v13.2.2 includes a wrong backport, which may cause mds to go into 
'damaged' state when upgrading Ceph cluster from previous version. 
The bug is fixed in v13.2.3. If you are already running v13.2.2, 
upgrading to v13.2.3 does not require special action. 

* The bluestore_cache_* options are no longer needed. They are replaced 
by osd_memory_target, defaulting to 4GB. BlueStore will expand 
and contract its cache to attempt to stay within this 
limit. Users upgrading should note this is a higher default 
than the previous bluestore_cache_size of 1GB, so OSDs using 
BlueStore will use more memory by default. 
For more details, see the `BlueStore docs <http://docs.ceph.com/docs/mimic/rados/configuration/bluestore-config-ref/#automatic-cache-sizing>`_. 

* This version contains an upgrade bug, http://tracker.ceph.com/issues/36686, 
due to which upgrading during recovery/backfill can cause OSDs to fail. This 
bug can be worked around, either by restarting all the OSDs after the upgrade, 
or by upgrading when all PGs are in "active+clean" state. If you have already 
successfully upgraded to 13.2.2, this issue should not impact you. Going 
forward, we are working on a clean upgrade path for this feature.
