The point is that the (devel) manual is referring to some release only URLs:

    https://ftp.gnu.org/gnu/guix/

The images there are only updated when a new release is out.  It is not
a rolling-release URL updated by the CI but a very stable URL manually
updated (I guess).

This URL in the manual is generated by

@indicateurl{@value{BASE-URL}/guix-system-install-@value{VERSION}.x86_64-linux.iso},

where VERSION is from version.texi generated at compile-time, IIRC.

The simplest is to add a warning note mentioning the issue and pointing to:

    https://guix.gnu.org/en/download/latest/

A more convoluted solution would to introduce another version label as
RELEASE-VERSION and use it in these places in the manual.
