Negative, I just downloaded it, and there is no added support for the Mavic Mini or Mavic Air 2 in today's release of SDK 4.12. (they did add support for the Matrice 300 RTK though). Sorry to burst your bubble.
I am wondering if they will drop SDK support for all new drones that are not in professional lineup since Air 2 is not a newbie drone like Mini was supposed to be...
Maybe they'll at least let Mavic 3 pro and Phantom 5 users use SDK?
Or are they making entirely new SDK for new Fly platform?
