Ah, I took a look and it seems that they are basically the same (multiple-bibliographies -> multibib in the transition to pandoc-ext) but their commit histories look different so there's obviously a bit more to it.

Anyway, multiple-bibliographies avoids the problem by always running citeproc as a JSON filter (via pandoc --citeproc for recent pandoc versions) and passing the --quiet flag.

I guess I'll use multiple-biographies for now, and look into how best to update pandoc-ext/multibib, which really should be the "official" version.

Any thoughts from anyone on whether utils.citeproc() could provide a 'quiet' argument (or equivalent)?

Thanks!

It seems to be an older version of multibib, but I never had the problemm you report with it.
