apply_filters( 'wp_save_post_revision_check_for_changes', bool $check_for_changes, WP_Post $latest_revision, WP_Post $post )

Filters whether the post has changed since the latest revision.


By default a revision is saved only if one of the revisioned fields has changed.
This filter can override that so a revision is saved even if nothing has changed.
