Update list of supported devices from Gluon 2020.2 #2
Description
We are now on Gluon 2020.2, which of course gives us an updates list of supported devices, which we already have the images built for. What is missing is an according update of the firmware download site.
Update the downloads.json according to the Gluon list and cross-check it with our directory listing.
Please also add the 🆕 emoji label to these devices and remove the current labels, because those are obviously not new anymore.
