+features:
+  - Support separate oslo.messaging services for RPC and Notifications
+    to enable operation of separate and different messaging backend servers.
+deprecations:
+  - |
+    The rabbitmq server parameters have been replaced by corresponding
+    oslo.messaging RPC and Notify parameters in order to abstract the
+    messaging service from the actual backend server deployment.
