From the GitHub release page:
Woohoo! After our first stable release with 1.0.0 we’re back to breaking things while we improve them. DO NOT use this release if all you want to do is try CircuitPython. 1.0.0 is much better for playing around.
However, 2.0.0 is shaping up to have some awesome new features. Here is a short list:
- Update to MicroPython 1.9.1 which supports mounting multiple file systems at once.
- Introduce a
storagemodule to facilitate mounting and unmounting file systems.

- Increase heap size from 16k to 20k. This means more code can be loaded. Thanks @dhalbert!
- atmel-samd: Introduce
audiobusio.PDMInfor recording sound to memory from a PDM microphone such as the one on the CircuitPlayground Express.
Moving from 1.0.0 to 2.0.0 is not a perfect process. There are a few things that break when doing so.
- mpy files compatible with 1.0.0 are NOT compatible with 2.0.0 because MicroPython changed the format. A beta bundle is available here. (Its built by changing the branch of circuitpython in the bundle repo before building it.)
