Subscribing to GitHub releases

Oh wow, this is handy. Noting this down! You can subscribe to a GitHub repo’s releases via RSS (thanks, trusty old StackOverflow). I wanted to keep an eye on the Wallabag repo, since I made a PR about some relative URL referencing being broken. You can do that via RSS! GLORIOUS RSS! Just append .atom to any releases page, e.g. https://github.com/wallabag/wallabag/releases.atom.
