I don't know exactly what volumio are doing. But librespot itself does currently still work. Who knows for how long (I doubt Spotify themselves know what they are doing). Librespot is transitioning to the new API, that API has already been implemented by other ports e.g. Librespot-java (and psst). It's not a pure Web API. It's a messy mix.
