One consistency change thanks to @ladyada! This release was made from the stable branch. The master branch is now working towards the 2.0.0 release.

This release is based on MicroPython 1.8.7.

Change highlights since 1.0.0-rc.3:

  • atmel-samd: Change to non-blocking mode for streams. That means UART.read() will return None when no data is available instead of raising OSError.
  • atmel-samd: Reboot to bootloader after 1200 baud serial connection is closed. Arduino uses this to flash a new sketch.
  • atmel-samd: Give on-board flash file systems unique Volume IDs based on the serial number of the MCU.
  • atmel-samd: Prep for Gemma M0 and Trinket M0.

To install, download a .bin file and follow the guide here for M0 and here for ESP8266.

Have a Feather M0 Express, Metro M0 Express, or Circuit Playground Express? Download a .uf2 and follow these instructions. To install our libraries simply download the latest bundle and copy the lib folder onto your CIRCUITPY drive.
