Woensdag is er niet alleen een nieuwe versie uit de 2.0.x-ontwikkeltak verschenen, ook in de 2.1-tak, die als alpha beschouwd moet worden, is een nieuwe versie uitgebracht. Nieuw  in versie 2.1 is de ondersteuning voor trackers en web-seeds via magnet  links en voor rss-feeds in de WebUI. Diezelfde WebUI maakt nu ook gebruik van versleuteling en zou verder geen port-forwarding meer nodig hebben. De bedoeling is echter dat er nog meer  nieuwe functionaliteit toegevoegd gaat worden.
