You can check the edit history yourself by just clicking on the “View History” button and then pressing the “cur” button next to the revision entry you want to see the diff for.
Note that if the edit history is long or you are doing a lot of checks, there are tools to bisect WP edit histories: at the top of the diff page, “External tools: Find addition/removal (Alternate)”
