2021-05-23 Rerun commentary: This run of comics in the PNG image file format has prompted a reader to report a bug in the RSS feeds of the comic - namely that PNG comics embedded into the RSS feed don't work properly. Or at least they didn't work properly, because I've now fixed it. (Hopefully.)

Such are the hazards of using a default format, and then very occasionally using something different. That bug had probably been there for more than 10 years, and either nobody had ever noticed or nobody had ever bothered reporting it to me before.

Honestly, I'm more surprised that people still use RSS feeds these days. They seem to have been a good idea that most people have now given up on.
