This feature records changes made to app settings as a simple change history.
You can check when changes were made, who made them, and a summary of the operations. This can be useful for troubleshooting issues or reviewing specific setting changes.

• Up to 50 records are displayed in the change history of app settings. When the number of records exceeds 50, the oldest records are automatically deleted.
• Deleting an app also deletes its change history of app settings.
  However, if the app is restored within 14 days, the change history of app settings will also be restored.
• For apps that were activated before this feature was released, the change history of app settings will be recorded starting from the release.
• If you temporarily disable this feature in the update options, setting changes made during that period will not be recorded. Once re-enabled, the previously recorded change history will be displayed.

Only users with management permission for an app can view the change history of its settings.
