2) From the revisions box
Scroll down, past the visual editor, until you see the “Revisions” box, as shown below. The contents of the revisions box lets you know who made changes when to the page/post.
If you don’t see a revisions box, check your screen options.
If you’d like to compare 2 revisions, one of which is not the current version, check off the “Compare any two revisions” box, outlined in orange above. This will give you an additional slider you can use to select the second revision.
