View Historical Tracking Reports in Lightning Experience
Where: This change applies to Lightning Experience in Enterprise, Performance, Unlimited, and Developer editions.
Why: Prior to this release, you could view historical tracking reports that were in matrix format in Lightning Experience. Now you can view all supported formats (tabular and matrix).
How: Now, when you click on a tabular historical tracking report from the Lightning Experience Reports page, the report runs and is displayed. For tracked fields, the Show Changes and Format Changes options are available for viewing the changes between the historical value(s) and the current value..
