Configuring DNS in general was there before, but there are a couple of NextDNS-specific things that went live: automatically using DoH when using NextDNS, setting profiles on a per-device basis so you can vary what things are blocked or not, and optionally sending client info to NextDNS so that your NextDNS dashboard gives you a better picture of what devices are querying what. And there's a little UI polish coming for the admin panel to show NextDNS configuration a bit more cleanly, but that's not live yet.
