>= 12.1.2
---------
-* The "journaler allow split entries" config setting has been removed.
-* The 'apply' mode of cephfs-journal-tool has been removed
-* Added new configuration "public bind addr" to support dynamic environments
- like Kubernetes. When set the Ceph MON daemon could bind locally to an IP
- address and advertise a different IP address "public addr" on the network.
-* RGW: bucket index resharding now uses the reshard namespace in upgrade scenarios as well
- this is a changed behaviour from RC1 where a new pool for reshard was created
* When running 'df' on a CephFS filesystem comprising exactly one data pool,
the result now reflects the file storage space used and available in that
data pool (fuse client only).
