Why are we doing this?
History and dif pages are used by editors and readers to understand how an article has changed over time. For editors, these pages are integral for gathering context around notifications and are key elements in a variety of common workflows.
As a user of the iOS app, I would like to be able to see how an article has changed over time by comparing two different revisions of an article.
