Structured documents and unstructured files maintain a history of changes by version record in the repository.
When a structured document or unstructured file is imported into the repository, a copy created from an existing repository object, or when a structured file is created in the repository, Astoria begins to track the object with an initial historical version record.
Subsequent changes to the object that are saved or checked in to the repository are tracked with a new version record. Execute the Show History or List History command on repository objects to see details about the object's revisions and perform actions on the versions.
