+1. Bump version number in `pyproject.toml` and `hwilib/__init__.py`, generate the setup.py file, and git tag release
 2. Build distribution archives for PyPi with `contrib/build_dist.sh`
 3. For MacOS and Linux, use `contrib/build_bin.sh`. This needs to be run on a MacOS machine for the MacOS binary and on a Linux machine for the linux one.
