No matter how much stuff gets released on the scene, every single system should have a heat manager installed to keep the system operating at the lowest possible playing temperature. One of the most popular tools to make that happen is Estwald's Control Fan Utility. This is not an official update per se, but Evilnat has done the community a service by updating that particular suite for the latest 4.55 custom firmware variants. Having an updated console that can play backups without fear of overheating? Sounds like a winning combination to me!
