When reviewing a scheduled change to a Release it would be helpful to be able to see what is changing vs the current version of the object. Without it, most blobs are too big to review in a useful way. A diff, similar to what we do in the Releases History UI, is likely the best way to show this. It's only needed for change_type "update" (inserts are an entirely new blob, and deletes remove an entire blob). This may need some backend support to generate the required diff.
I submit it would be even better to show the change in the context of the other rules for the same product+channel.

I might be misunderstanding your comment, but I'm not sure how it fits here since this bug is about Releases? Bugs 1316948 and bug 1329524 might be more relevant, where we're talking about being able to query the state of things at a particular point in time.
Whoops, sorry about that.
