The Value Set Audit Log (also known as a change log report) provides a report for value set authors and stewards to review time/date stamps for all updates to the value set’s definition, expansion, and metadata, along with the specific author or steward group members who made the changes. All columns of the downloadable spreadsheet are sortable and searchable.
