This release removes the use of max_size for displayio Groups in the examples and library itself. Circuitpython version 6.3.0 removed the need for this parameter and 7.0.0 will remove it entirely.
To use in CircuitPython, simply install the [Adafruit CircuitPython bundle](https://circuitpython.org/libraries).
To use in CPython, `pip3 install adafruit-circuitpython-display_shapes`.
Read the [docs](http://circuitpython.readthedocs.io/projects/display_shapes/en/latest/) for info on how to use it.
