This release renames the arguments used to initialize the library. The new names are more properly descriptive of the type of objects expected (`DigitalInOut` rather than `Pin`). This is a breaking change for any user code that initializes this library using named keyword arguments rather than relying on positional arguments only. If your code uses named keyword arguments you will need to change it to use the new names `cs_dio` instead of `cs_pin` etc...
Thank you tekktrik for clarifying the arguments.
