 > Just found this issue and wanted to add that my team is looking for this
 exact functionality (allowing users who don't have permissions to publish
 items to view revision history for accountability/historical reasons). Are
 there any updates on when this might be added since it got taken out of
 the 5.4 release?


 Besides the noted change in the revisions.php code mentioned above - I
 believe altering the function wp_ajax_get_revision_diffs in ajax-
 actions.php would provide most of what our team needs.

 something like:

 {{{
 if ( ! current_user_can( 'edit_post', $post->ID ) || !
 current_user_can('read_revision', $post->ID) ) {
                 wp_send_json_error();
         }

 }}}
