+upgrades:
+  - mongodb.server.cluster no longer hardcodes the telemetry nodes' hostnames
+    in favor of using `openstack_telemetry_node{01,02,03}_hostname` params,
+    allowing custom hostnames to be used.
+
+    Configuration example:
+
+    .. code-block:: yaml
+
+        parameters:
+          _param:
+            openstack_telemetry_node01_hostname: mdb01
+            openstack_telemetry_node02_hostname: mdb02
+            openstack_telemetry_node03_hostname: mdb03
