Thanks Stefan for your awesome post here (I’m a bit slow on the uptake but better late than never). I have used the ?IncludeVersions=TRUE to show all updates to InfoPath forms in a forms library. This seems to give users some sense of security (they don’t really believe versions are being tracked until they can SEE them).
You can also add multiple lists to one list view page and apply the filter. It will show the versions for all lists on the page. Good for a “versions” page rather then expecting users to find use the Version History menu option. Check out Stefan’s post to see how you can also use other filters with the versions query string parameter. Very very cool and super easy.
