What's the supported Networking model?

As in subject, neither a Google search fully clarifies this.

Godot has a high level networking API built with Enet. See this post for the announcement article which may answer your question.

EDIT: Oh, by the way, the new multiplayer API is only in Godot 3 (or Godot 2.2 legacy if you build it from source)

Thanks. I also have a general problem with the website: I didn't receive any email from the forum flagging this answer.

Sorry, I were meaning I didn't receive the email notification.
