+    Added two new classes to support Elasticsearch v2 and v5 and Kibana
+    v4 and v5.
+    Update the Elasticsearch and Kibana classes in the
+    ``classes/cluster/<cluster_name>/stacklight/server.yml`` file of
+    the Reclass model of your MCP deployment according to the required
+    versions:
+
+    #. For Elasticsearch, change the ``linux.system.repo.elasticsearch`` class
+       to ``linux.system.repo.elasticsearch.2`` or ``linux.system.repo.elasticsearch.5``.
+       To deploy Elasticsearch version 2, specify the ``elasticsearch_version: 2``
+       parameter in the same file.
+    #. For Kibana, change the ``linux.system.repo.kibana`` class to
+       ``linux.system.repo.kibana.4`` or ``linux.system.repo.kibana.5``.
+       To deploy Kibana version 4, specify the ``kibana_version: 4``
+       parameter in the same file.

+    Updated Elasticsearch and Kibana to v5. Elasticsearch and Kibana v5
+    are now installed by default.
+
+    To upgrade existing Elasticsearch and Kibana installations to v5,
+    follow the procedures described in the MCP Operations Guide.
+
+    .. TODO: add a link to the upgrade procedure.
+
+    Kibana versions prior to 5.6.x are incompatible with Elasticsearch
+    5.x. Therefore, once you upgrade Elasticsearch to v5, you must also
+    upgrade Kibana to v5 as described in the MCP Operations Guide.
