+* Day 1: the new "Cluster Expansion Wizard" will guide users through post-install steps:
+ adding new hosts, storage devices or services.
+* NFS: the Dashboard now allows users to fully manage all NFS exports from a single place.
+* New mgr module (feedback): users can quickly report Ceph tracker issues
+ or suggestions directly from the Dashboard or the CLI.
+* New "Message of the Day": cluster admins can publish a custom message in a banner.
+* Cephadm integration improvements:
+ * Host management: maintenance, specs and labelling,

+ * Alerts can now be sent externally as SNMP traps via the new SNMP gateway service
+ (the MIB is provided).
+ * Improved integrated full/nearfull event notifications.
+ * Grafana Dashboards now use grafonnet format (though they're still available
