The program offers a detailed list of revisions that have been made to the software.
Click Help > Enhancement/Change History. The following window will be displayed:

This window is dynamically built by calling all subsystem modules in the software. In this manner the subsystems themselves contain the information on the changes that have been made.
This list can be set to display enhancements only, or it can display enhancements and changes/corrections. When the list is set to display both enhancements and changes/corrections, it can be sorted by version or by module.
