Now that Hummingbird is Kitsu, Hachidori is now updated for Kitsu. Currently, Hachidori is the only scrobbler that supports Kitsu. With that, Hachidori 2.0 is now in beta. While it’s mostly stable, there might be a few bugs. Report them on Github or on Kitsu forums if you experience any bugs.
To update, simply check for updates. You can download the new release from the home page.
