I usually maintain a table, named tblVersion, with the latest version number and other information. In fact, you can keep a running version control system in this table and, whenever you need to know the version number, simply look for the DMax of the version number in this table. With each version record, you can keep a memo field with a narrative of all the changes from the previous version. You can have a date field to record the version date, a text field to record who released the version, etc., etc. etc.
