From the GitHub release page:
After the big
nativeiosplit it was time for some bug bashing. The biggest feature is the ability to use the NeoPixel on the Feather M0 Express.
This release is based on MicroPython 1.8.7.
Change highlights since 0.9.4:
- Support NeoPixel sharing on Express boards. Simply use it as normal and the underlying system should share it.
- Fix serial receive on Huzzah Breakout, Feather Huzzah was OK.
- Fix PulseIn timing issues for DHTxx and IR support.
- Fix PulseIn reset issues that could hard fault the board.
