+  Updated the StackLight components to newer versions
+
+upgrade:
+  - |
+    Updated the following StackLight components:
+
+    - Prometheus server to version 2.0.0
+    - Alertmanager to version 0.11.0
+    - Pushgateway to version 0.4.0
+
+    .. important::
+
+       The new version of Prometheus is not backward compatible
+       with previous versions. Therefore, you must upgrade the
+       monitoring stack as described in the MCP Operations Guide.
+
+       If You want to stick to 1.7 (NOT RECOMMENDATED), update
+       reclass model:
+
+      .. code-block:: yaml
