I just tested QuForm (Only plugin installed) with the 4.4 beta version and it throws a deprecated function notice. (Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0). Since WordPress 4.4 is about to be released Dec 8th, it may be something you may start looking into it. In fact, on Aug 2nd, WordPress emailed all plugin developers (the ones on the repository) about many functions that will be replaced after 4.3 and that many plugins were going to stop working properly if not updated.
