This release adds support for blocking select, switches to LLVM 9, improves CGo support, improves support for the ATSAMD51 ("M4") chip, and generally has a lot of improvements and bug fixes throughout. It also adds support for a number of new boards: the Adafruit Feather M4, the Adafruit Metro M4 Express AirLift, the PineTime dev kit, and the "X9 Pro" smartwatch.
