5.0.1: drop trailing comma in a keyword-required arg list to accommodate Python 3.5.
5.0.0: The `stop=` keyword is no longer supported for `I2CDevice.write()` and `I2CDevice.write_then_readinto()`, because the underlying `busio.I2C` API no longer supports the keyword either. See https://github.com/adafruit/circuitpython/pull/3195 and https://github.com/adafruit/circuitpython/issues/2082.
This is an incompatible change for CircuitPython 4.x, which is no longer supported.
To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://circuitpython.org/libraries).
