KUMA stores the change history of resources in the form of versions. A resource version is created automatically when you create a new resource or save changes made to the settings of an existing resource.
The change history is not available for the Dictionaries resource. To save the history of dictionaries, you can export data.
Resource versions are retained for the duration specified in the Settings section. When the age of a resource version reaches the specified value, the version is automatically deleted.
