Just pushed a fix that should make RSS feeds work properly (you will have to resubscribe to the RSS feeds, if you did so a while ago). Thanks to squirrelInHell who made me aware of the deeper problems with our RSS feed (that my RSS reader seemed to mostly automatically patch, but which other people ran into).
Yeah, this is on my radar to fix. It should probably be pretty straightforward to fix, so a PR on our Github is also welcome.
