Where can I find the up to date F# Core Library reference?

Question

It appears current F# documentation from Microsoft is missing the core library. The only documentation I could find looks quite dated and is from 2017. I spent a surprising amount of time (this being 2020 and F# being around for a while now) with google searches, trying to find the documentation for FSharpValue.MakeUnion method and could not find anything useful that appears to be from the horse's mouth.

Searching for a method the above method name in MS's documentation produces the following result (and all results on Ms docs link also leads to nothing):

Where should I be looking?

The F# API docs are now located at: https://aka.ms/fsharp-core-reference (which currently just redirects to https://fsharp.github.io/fsharp-core-docs/).

For example FSharpValue.MakeUnion can be found at: https://fsharp.github.io/fsharp-core-docs/reference/fsharp-reflection-fsharpvalue.html#MakeUnion
