Thanks for the great response to the beta everyone! Here is a new release to test. Its got much of the same CircuitPython code as before but has been upgraded to MicroPython 1.8.7 code and GCC 6.2. So, please test it out and let us know what you think.
To install, download a .bin file and follow the guide here.
The Vagrantfile has also been updated to use the new GCC. To update it, save all the code you care about out of the vm, destroy it, pull and re-up the vm.
Changes:
* Merge in MicroPython 1.8.7
* Switch to GCC 6.2 (arm 2016q4 release)
* Change 0RX style pin names to two names, D0 and RX on some boards.
* Remove the `framebuf`. It made the binaries too large with all of the extra functionality added in 1.8.7.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
