Does on port 443 need to be enabled for 0.8.0?

Connection notes state that outbound https (port 443) to for using the API. Is this required for devices running 0.8.0 or is just TCP traffic to on port 5683 sufficient?

Wi-Fi devices (Photon/P1) only communicate with the cloud on outbound TCP 5683 (CoAP).

The API port ( port 443) is used by the Particle CLI, Particle Dev (Atom IDE), Particle Web IDE, mobile apps, and of course direct access to the cloud API. Devices don’t access the API that way, however.
