Great stuff!! :slight_smile:

Is an update of mbed-os also intended soon? mbed-os 5.11.0 is now now 4 release versions ahead of PIO’s version (5.10.1)

I hope @valeros will prepare New Year’s gift for us. Would be good to have 5.11.1 with all bug fixes :blush:

Yeah! The update to the arduino core for my discovery boards were much needed. Good work.
