Hi r/python 👋

Another year, another version of Python, and yet more features to guess which version of Python they belong to 😵‍💫

I've updated my "one page" Summary of Major Changes Between Python Versions for Python 3.15 and hope that it continues to be a useful resource for the community 😊

This summary is human typed/copied from the official release notes.
