I have really not had to think about it very much at all. It auto-updates itself. Every once in a great while this breaks something but I can’t remember the last time that happened. It’s still using the custom styles I built over those ten years – one for the main body of the site, plus a few more for each of my comics. I suspect that I may keep on using this same setup for another decade or two, though I may change my mind if they stop updating the plugin that lets you keep on using the original editor instead of the new one that wants you to make a bunch of “blocks” and organize them and would probably require me to crack open big chunks of PHP I kludged up back in 2012 to make it properly work with those blocks.
