Your instinct is right — wait for SparkBox to update them rather than doing it yourself. Each app is pinned to a version that's known to work with the whole stack (SABnzbd is held at 4.4.1 on purpose), and updating one from inside the app gets wiped the next time SparkBox refreshes it, which can leave things half-updated. Newer app versions arrive with SparkBox releases: when Tom ships one, open a terminal and run sudo sparkbox upgrade, and the newer SABnzbd, Sonarr and Radarr come along with it. He ships these regularly, so you won't be stuck on 4.4.1 for long.

Same upgrade, just two ways to start it — both download the latest SparkBox release and keep all your settings, data and apps. The only real difference is recovery. The dashboard Update SparkBox button runs it from a small helper inside the box, then checks everything came back up and undoes itself automatically if it did not. The terminal command sudo sparkbox upgrade does the same upgrade from the box itself, so if anything wobbles you undo it yourself with sudo sparkbox rollback. Either one brings you the newer SABnzbd, Sonarr and Radarr.
