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, copy mpy files to your lib directory on the CIRCUITPY drive.
To use in CPython, pip3 install circuitpython-displayio-swtichround
Read the docs for info on how to use it.
