Hello Clément,
It is possible to search for the last build of a given job using the Web interface search form. For example, http://ci.guix.gnu.org/search?query=spec%3Aguix-master+gajim which corresponds to the search "spec:guix-master gajim", will show the last build job for gajim on master. A build job history is also displayed on the build details page. Closing this one, Thanks, Mathieu
