There has been a change in the view menu. "Hide Whitespace" has been changed to "Show Whitespace" (see. 124686).
This should be changed in Lo Help as well: https://help.libreoffice.org/7.0/en-GB/text/swriter/main0103.html?&DbPAR=WRITER&System=WIN
Perhaps it is also possible to add informations, that are mentioned in bug 108335.
Olivier Hallot committed a patch related to this issue.

Thanks, for quick response, Olivier. Is it possible to add the information, that hiding whitespace is only possible in Single-page view? (This would also cover bug 108335, because if you change page View to Automatic it changes to Multi-page view.)
