This release allows boards with different versions of libgpiod to be used. Some versions of libgpiod had a `Chip` property and some had `chip`. This allows either to be used.
For more recent version of libgpiod, Pull up and Pull down support was added and this release includes updates to make use of that.
To use in CPython, `pip3 install adafruit-blinka`.
Read the [docs](https://circuitpython.readthedocs.io/projects/blinka/en/latest/) for info on how to use it.
