+### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
+
+It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
+
+Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
+
 ## Persistence
 
 The [Bitnami Phabricator](https://github.com/bitnami/bitnami-docker-phabricator) image stores the Phabricator data and configurations at the `/bitnami/phabricator` and `/bitnami/apache` paths of the container.
