Well I took the   first entry google offered.
Great, I just looked into the http address:

https://ftp.gnu.org/old-gnu/Manuals/elisp-manual-21-2.8/html_node/elisp_143.html

It says *old* sigh! Sorry.

However I never really paid attention to defcustom,
so the nifty easy to use feature "*" 

as in

(defvar latexdiff-perl nil
"*Whether to use latexdiff based on perl or not, default is NIL.")

Is gone?

But

https://www.gnu.org/software/emacs/manual/html_node/eintr/defvar-and-asterisk.html#defvar-and-asterisk

Suggests that I still can use it. But it does not work for me,
