+ * 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'.
 +
 +* Dashboard: Rearranged Navigation Layout: The navigation layout has been reorganized
 +  for improved usability and easier access to key features.
 +* Dashboard: CephFS Improvments
 +  * Support for managing CephFS snapshots and clones, as well as snapshot schedule
 +    management
 +  * Manage authorization capabilities for CephFS resources
 +  * Helpers on mounting a CephFS volume
 +* Dashboard: RGW Improvements
 +  * Support for managing bucket policies
 +  * Add/Remove bucket tags
 +  * ACL Management
 +  * Several UI/UX Improvements to the bucket form
 +* Monitoring: Grafana dashboards are now loaded into the container at runtime rather than
 +  building a grafana image with the grafana dashboards. Official Ceph grafana images
 +  can be found in quay.io/ceph/grafana
 +* Monitoring: RGW S3 Analytics: A new Grafana dashboard is now available, enabling you to
 +  visualize per bucket and user analytics data, including total GETs, PUTs, Deletes,
 +  Copies, and list metrics.
