Update 2018-02-12

Update 2018-02-12: added that Danceable Feast has ended with 2017. It's not clear from their website, but Lindsey Dono forwarded me an email from their organizers that does clarify that this is the end. Also added Dancing Fool (2x) ending with 2017, and Supersonic starting in 2018. That makes ten stopping and five starting.
