Flow Revision

Flows Revisions track every change made to a Flow resource. Revisions are automatically created when a Flow is created or updated. Each revision is read-only and immutable (cannot be updated or deleted).

For convenience, the latest Revision and latest published Revision can be fetched using the magic identifiers LatestPublished and LatestRevision in place of an integer.

Fetching the parent Flow resource will always return the latest Flow Revision.
