An interesting blog post from Microsoft on some upcoming Azure Sphere features. We're currently on 19.09, so maybe these are in 19.10, although there was no timeframe specified.
A lot of the features seem focused on the difficulty people had getting started so it's good that thy're taking notice of the experience of those struggling. I'm guessing all those free boards are money well spent on UX research! I must admit personally I'd have liked to see more functionality on the M4 cores, but I can see why that's less of a priority.
