What is the difference between merged revisions and superseded revisions?

When you make two or more project copies from a master document, only one of them may be released as the new master document revision. The first one to be released wins. But what about the changes made in the other project copies?

Meridian provides three ways to resolve the remaining project copies made from the same master document. For more information about these options, see Reconcile with an updated master document.
