Cc.LoaderScene.preload in v3.2

I am looking in the documentation here:
http://www.cocos2d-x.org/reference/html5-js/V3.2/index.html

but can not find a reference to cc.LoaderScene. A reference to it exists in the v2.2 documentation:
http://www.cocos2d-x.org/reference/html5-js/V2.2/symbols/cc.LoaderScene.html

Has the process for loading a scene changed from v2.2? Or is it simply missing from the documentation?

I have to say that documentation has always been of a poor quality for cocos2d-x. The documents seem to be out of date most of the time, referring to a deprecated workflow or a previous version. I’ve also encountered multiple documents that cover the same topic but contain conflicting information. More often than not I have to dig into the forums to find answers that should be in the documentation. Like the question I’m asking in this post.

Is there a definitive resource for all things v3.2?
