Where is the current Vibe 4.08 documentation hidden?

If you follow the path linked from the product page at: https://www.microfocus.com/en-us/support/Vibe it links you to https://www.novell.com/documentation/vibe4/ which doesn't respond.

Substituting random similar urls (https://www.microfocus.com/documentation/vibe/ or https://www.microfocus.com/documentation/vibe4/) links to documentation for Vibe 4.01 and 4.02 respectively.

Where does one find the current docs?
