+    Deprecates support for deploying MongoDB. In Victoria support for
+    deploying MongoDB will be removed from Kolla Ansible. Note CentOS 8
+    already lost support for MongoDB due to decisions made upstream.
+
+    This affects Panko as it will no longer be possible to get automatic
+    deployment of MongoDB database for it. However, the default, SQL,
+    backend is and will be supported via MariaDB.
+
+    MongoDB lost its position in OpenStack environment after
+    controversial relicensing under their custom SSPL (Server Side
+    Public License) which did not pass OSI (Open Source Initiative)
+    validation.
