And thank you @github for the @trmnl!

And finally, for now, the best one.

When I make a typo in the release notes, I no longer need to type in the URL for the admin site, then click to see release list, find the relevant release, and click to edit.

Instead I can click the "Edit" button right there on the page!!!

Thanks to @Monorepo for doing most of this, which needed changes to both the release process and the website: releases since 13th January now show SHA-256 checksums instead of MD5!

The release overview table at https://www.python.org/downloads/ is now generated from the PEPs API (https://peps.python.org/api/) instead of being hardcoded.

This and some of the earlier stuff means three more manual steps have been removed from the release process, PEP 101!
