German, and a couple of things that were only ever in English. • German throughout, with a language picker in Settings → System. • German note names (H/B) as a switch of its own: being taught H is not the same as reading German. • Recent songs in the side panel — the last five you opened or read from. • Settings split into Chords, System and About tabs, with the version and licence on About. • Relicensed to GPL-3.0-only; wordmark and icon are CC BY 4.0.
