The Developer's version control system automatically keeps track of new documents and changes to existing documents as they are checked in and out of the server. A running history of each document is created as changes are checked in. The history of a document is a sequential list of the document versions starting with 1, along with their dates, who made the changes, and any comments made during check-in to explain the changes in the document. This history allows you to view a previous version of the document and/or roll back to a previous version. History is only available when you are online.
Note: A new or converted document is automatically assigned a version of NEW until it is checked in for the first time. The document is assigned a version of 1 after the first check in.
