Why did the Confluence Slack integration take away the "View Diff" feature?

[Ben Johnson]

The old version (as of a few days ago) of the slack integration for Confluence would slack me when a page changed that I'm subscribed to. In that slack message it had a button for "View Diff" which was amazingly useful and I used it all the time (I wish a view diff link was provided in the emails too). It seems that button was taken away recently and it would be really nice if it could be added back.
