As I understand it, there is currently no side-by-side comparison option ("diff") between versions at, like at

It would be great a great feature to have, for better understanding updates on units like -- ideally directly on the page, alternatively as a link to

This was also asked about six years ago, but many things have probably changed since then, and it might not be as difficult to add it today:

An example mock-up, where the unit number "439311424" is a link. It could also be a link called fx "View diff" next to "View History" at the bottom, pointing to a diff view of the latest revision:

Thanks @scai for your feedback and link, it was really constructive. And thanks for suggesting that feature more than five years ago in "Better history diff by adding colorization of changes #738" in the Github issue you linked to above.

Do these provide what you need?
