you can grab revisions from wpdb with smth like $revisions = $wpdb->get_results(“select * from {$wpdb->posts} where post_parent={$post_id} and post_type=”revision””) after selecting a revision you could use some js diff tool like http://cemerick.github.io/jsdifflib/demo.html
I had a look at the wp_revisions_to_keep() function. There’s a filter called wp_revisions_to_keep that overrides the value of WP_POST_REVISIONS. Here’s an untested example (PHP 5.4+): add_filter( ‘wp_revisions_to_keep’, function( $num, $post ) { // Post Types and Revision Numbers – Edit to your needs $config = [ ‘post’ => 10, ‘page’ => 9, ‘cpt’ => 8 … Read more

So it’s different from revisions and for every post there will be only one autosave per user. This is from the document: There is only ever a maximum of one autosave per user for any given post. New autosaves … Read more
You can use wp_get_post_revisions ( int|WP_Post $post_id, $args = null ). It returns an array of revisions for the passed post ID or an empty array if a passed post does not have any revisions. Note that the $args parameter accepts all parameters valid for WP_Query $q = wp_get_post_revisions( 513 ); echo count( $q ); … Read more
So via lots of head banging and experimentation I managed to get a solution to letting editors/admins review the post whilst a previous one stays live is rather convoluted but does work. The key thing I did was to create a new post status which I call awaiting. In the admin it appears as “changes … Read more
