 * RGW: Compression is now supported for objects uploaded with Server-Side Encryption.
   When both are enabled, compression is applied before encryption.
+* RGW: the "pubsub" functionality for storing bucket notifications inside Ceph
+  is removed. Together with it, the "pubsub" zone should not be used anymore.
+  The REST operations, as well as radosgw-admin commands for manipulating
+  subscriptions, as well as fetching and acking the notifications are removed 
+  as well.
+  In case that the endpoint to which the notifications are sent maybe down or 
+  disconnected, it is recommended to use persistent notifications to guarantee 
+  the delivery of the notifications. In case the system that consumes the 
+  notifications needs to pull them (instead of the notifications be pushed 
+  to it), an external message bus (e.g. rabbitmq, Kafka) should be used for 
+  that purpose.
