One of the first things you'll spot launching Android 12 Beta 2 is a big notification that explains that Android's Adaptive Notifications are being replaced. Going forward, Android has "enhanced notifications" instead. The bundled explanation is a bit impenetrable, and there aren't any observable changes in notification behavior. Turns out that's because it's basically the same thing, Google's just changing the name and moving what controls it.
We spent a bit of time trying to dig into these enhanced notification changes when we first saw the notification, but couldn't spot any user-facing adjustments in behavior, just a change of branding in Settings for the "suggested actions, replies, and more" feature, which controls some of the app notification integrations that rolled out in 2020 (also tied to the Adaptive Notifications setting in Apps & notifications -> Special app access, which is also gone in Android 12).
