Thanks to remarks by Mojca and Alan, I did some testing with mkiv and my old setups for bibliography under mkii, and magically it works also with the new bibliography features of mkiv, that is without saying \usemodule[bib]. However somehow I couldn’t find an equivalent for the command \placepublications[criterirum=all] when one needs to give another title to the section containing the bibliography (as in the attached file). As I understand from Alan’s and Thomas Schmitz’ answers, the new bibliography features are not yet completely « production ready » for those people who need complex requirements (this is not my case…). However it would be nice if the new commands were made known somewhere, even without having a detailed manual (some people use quite elementary features and probably those may be obtained in less than ten commands…). Best regards: OK
