) Started testing texlive 2013 today - I have problems with bibliogrphy. I am working on a document which worked perfectly under texlive 2012. A) I installed when it moved to testing I moved all pacnew files over originals and ran fmtutil-sys --all B) Running biblatex I get: RUnning biblatex: This is BibTeX, Version 0.99d (TeX Live 2013/Arch Linux) The top-level auxiliary file: mbs-val-stochp.aux I found no \citation commands---while reading file mbs-val-stochp.aux I found no \bibdata command---while reading file mbs-val-stochp.aux I found no \bibstyle command---while reading file mbs-val-stochp.aux (There were 3 error messages) The command \printbibliography now does not generate any bibliography. Any suggestions how to fix this?
