+fixes:
+  - |
+    Updates the default Grafana OpenSearch datasource configuration to use
+    values for OpenSearch that work out of the box. Replaces the Elasticsearch
+    values that were previously being used. The new configuration can be
+    applied by deleting your datasource and reconfiguring Grafana through kolla
+    ansible. In order to prevent dashboards from breaking when the datasource
+    is deleted, one should use `datasource variables
+    <https://grafana.com/docs/grafana/latest/dashboards/variables/add-template-variables/#add-a-data-source-variable>`__
+    in Grafana. See bug `2039500 <https://bugs.launchpad.net/kolla-ansible/+bug/2039500>`__.
