Previous changes from v0.14.0

  • ๐Ÿš€ This is a big release with lots of small improvements. Some of the highlights include Go module support and the support for channel operations in interrupts for a few chips. This release also includes support for a number of new boards: the Adafruit Feather nRF52840 Express, the Adafruit PyGamer, the Sipeed MAix BiT with a 64-bit RISC-V MCU, the Teensy 3.6, the Seed WioTerminal, and the Seeed Xiao. Perhaps more interesting, it includes initial support for the Nintendo Switch.
