Is it possible to get hyperlinks to previous versions of a form, or even just see a list of changes to a Form Library item via Workflow History? If that wouldn't be available, what are the workarounds? So far what I can think of is to manually write column data to another list using a workflow anytime something is changed on the Form Library's items, but if there are any easier strategies, please share.
I'm pretty sure you can enable versioning on list. So you can view all changes in item history.
Will this suite your scenario?
