Is Realm C++ SDK still in preview?

I was going over the README here: GitHub - realm/realm-cpp: Realm C++

It says:

Realm is a mobile database that runs directly inside phones, tablets or wearables. This repository holds the source code for the C++ SDK Preview.

While at the same time, I see that it is already post version 1 and also this PR: Remove experimental namespace, Remove Alpha SDK by leemaguire · Pull Request #131 · realm/realm-cpp · GitHub

Makes me think if that “Preview” was just left out and needs to be removed.

@Mihir_Luthra Realm C++ SDK is dead and will never exit preview
