Might be worth mentioning that the repo has a Python 3.11 requirement.

Just a small thing I ran into during the setup process. It looks like urllib3 needs to be compiled with OpenSSL 1.1.1+ to make things work. Python 3.11 has this by default so it seems to easiest thing for people to do to get up and running quickly.

Sorry just seen this.

Diffenator2 is working fine on python 3.7+ in Github Actions. I think you're right that you still need OpenSSL though. For earlier versions of Python, I remember you had to run a shell script at the end of the installation process to install it.
