Where did the diffs go in Confluence page-changed emails?

I watch a number of pages in our wiki space, and I keep tabs on changes by reading the diffs that are included in the "someone updated this page" emails.

But as of a week or two ago, the diffs are gone! I just get "Alice updated this page" and a link to the page, but no indication of what was actually added or removed. This is a significant downgrade in functionality, as a lot of the edits are small and unimportant (so I'm not going to click through on every single email) but others are not (and so I'm going to miss some important updates).

I didn't change any settings, and I can't find anything relevant in the settings pages. Was this feature removed?
