GitHub provides several timeline resources in Atom format. That’s how I get latest info about projects that I follow and their fixed bugs and new features. Some of official RSS feeds are:

/* Repo releases */ https://github.com/:owner/:repo/releases.atom /* Repo commits */ https://github.com/:owner/:repo/commits.atom /* Private feed (You can find Subscribe to your news feed in dashboard page after login) */ https://github.com/:user.private.atom?token=:secret /* Repo tags */ https://github.com/:user/:repo/tags.atom /* User activity */ https://github.com/:user.atom
