I just logged in with my Tesla account and noticed there is a new section for "Notification" Did a quick probe, it seems like the data requested explicitly returned with a template for `Firmware update` as well as `Appointment` notification. The template suggest this notification will include Firmware title, Contents body and Button to do some action. I'd guess this coincide with Elon's recent tweet about incorporate firmware request for owners. I also checked my Model S car page, it still the same old design. So my guess is this might affect Model 3 fleet first.
