Unity UI where is the latest ScriptReference of UnityEngine.UI?

I can't find it in the latest ScriptReference both online or offline version.
I know now uGUI is a package of unity. so I :

open package manager ,
select Unity UI.
click the view document link. it open this url:

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/index.html

in this page, it says

and the link lead me back to the ScriptReference page(https://docs.unity3d.com/ScriptReference/).

I found that Script Reference of UnityEngine.UI disappered since Unity 2019.2.
I still can get the doc in older version (before Unity2019.2)

where can I find the latest doc ?
