I've noticed that when looking at the history for a page created with the "new" editing experience, the colours previously used to denote additions and deletions simply don't show up. It's very difficult to actually see the changes in a page. Newly added text simply looks the same as existing text, and deleted text has a strikethrough which just looks like text already formatted that way.
Is this a known issue? Such version differencing has long been a problem with Confluence (for instance, edit any cell of a table and the whole thing goes into the notification email, not just the cell edited). Will we see proper improvements here soon, something like GitHub or any other diff view?
