OBS build for debian 12

Hi, I am finding some confusion with the download documentation for debian:

• Main download page (https://www.knot-resolver.cz/download/) says to directly grab knot-resolver-release.deb from https://secure.nic.cz/files/knot-resolver/ yet it is not clarified whether this will then automatically update in case of security issues, nor whether it is fine for platforms different from amd64;

• There also seems to be an OBS build factory (https://software.opensuse.org/download.html?project=home%3ACZ-NIC%3Aknot-resolver-latest&package=knot-resolver) however going there, there seems to be still no debian 12. Would using debian_next be fine for the time being?

Can the download/install info for debian be clarified a little? In case there is an official debian repo, it is important to know where, particularly for cases where debian needs to be updated from one version to another one (e.g. bullseye to bookworm).

Thanks.
