I have been looking through the documentation and haven’t found anything that references “Versions” or “Version Browser”. Can’t see anything in menus which seems to be related to the new ‘Versions Browsing’ feature. Is this something that is in SD7 or is the versioning using Time Machine?
If you go to the Table of Contents and look under Glossary, you will see an entry for it.
Open a document that has been saved more than once, go to File -> Revert To -> Browse All Versions….
