Unity Multiplayer Functions Provided in Documentation Are Not Available in Unity

The documentation states this function signature: NetworkManager.ServerChangeScene(int). However, when writing code, the only available version is NetworkManager.ServerChangeScene(string), expecting a name for the scene to load. I'm using the NetworkManager singleton.
Source: http://docs.unity3d.com/ScriptReference/Networking.NetworkManager.ServerChangeScene.html

The source page above states this function signature in the description: NetworkClient.Ready(). However, the documentation and the available functions in code don't have it. The closest I can find is ClientScene.Ready(NetworkConnection).

Many thanks if someone from Unity can clear this up...

 

There are a couple other posts like this. Can someone from Unity comment on if this type of thing is usually updated in conjunction with patch releases or regular releases?
