E.g., https://help.libreoffice.org/Calc/Error_Codes_in_Calc doesn't state which version of LO it is relevant to. Search engines have it indexed and display in top results; people are confused that the content is not up-to-date (see e.g. https://ask.libreoffice.org/en/question/206010/mysterious-err540-error-code/?answer=206014#post-id-206014 ). Could we add a band above the legacy help pages stating something like "This help page is relevant to LibreOffice up to version X; for help pages for current version, go to https://help.libreoffice.org"?
