    without this feature will trigger the MDS to raise a HEALTH_ERR on the
    cluster, MDS_CLIENTS_BROKEN_ROOTSQUASH. See the documentation on this warning
    and the new feature bit for more information.
 +
+ * CephFS: Expanded removexattr support for cephfs virtual extended attributes.
+   Previously one had to use setxattr to restore the default in order to "remove".
+   You may now properly use removexattr to remove. You can also now remove layout
+   on root inode, which then will restore layout to default layout.
+ 
+ * cls_cxx_gather is marked as deprecated.
+ * CephFS: cephfs-journal-tool is guarded against running on an online file system.
+   The 'cephfs-journal-tool --rank <fs_name>:<mds_rank> journal reset' and
+   'cephfs-journal-tool --rank <fs_name>:<mds_rank> journal reset --force'
+   commands require '--yes-i-really-really-mean-it'.
+ 
+ * CephFS: Command "ceph mds fail" and "ceph fs fail" now requires a
+   confirmation flag when some MDSs exhibit health warning MDS_TRIM or
+   MDS_CACHE_OVERSIZED. This is to prevent accidental MDS failover causing
+   further delays in recovery.
