 # Changelog
 
+## 2023-09-07.1
+
+Added `$settings['deployment_identifier']` setting. This setting is used to determine if container
+needs to be invalidated and rebuilt. This should fix the issue where deployment fails due to changed
+service parameters in contrib modules.
+
+### Required actions
+
+Update `azure.settings.php` and `settings.php` files from this repository. Optionally you can make the changes manually, see:
