The manual should indicate on the first page which version it refers to (pdf)

[jammon]

All pdf manuals have on their first pages the label "Release latest", even the manuals for version 21 or 20. The html form of the manuals (https://docs.nextcloud.com/server/22/user_manual/en/ or https://docs.nextcloud.com/server/21/user_manual/en/) refers to the "latest" version without revealing which version that was at the time. The only clou is, that you can switch to some previous versions (21/20/19 or 20/19/18) which came before this specific document.

Please state on the first page and maybe on the header or footer of the subsequent pages to which version of nextcloud this document refers. The html docs as well should say prominently which version of nextcloud is documented there. Thank you.
