Notice - URL schema changes

Dear Reader,

As part of some long-overdue maintenance, I have changed the way image URLs are namespaced, since I wanted to make it easier to handle some corner cases (and also make it easier to manage future static generation).

The underlying server OS and Python runtime have also changed to Ubuntu 20.04 and Python 3.8, respectively (which brings it up to my regular standards these days, it was becoming a bit long in the tooth).

Since image URLs are also signed with an HMAC (which I rotate periodically to avoid getting my content ripped off wholesale), there might be some temporarily missing images until Cloudflare catches up.

Again, kindly remember that – the old URL will likely stop working after the holiday season.
