Sorry, I might not understand something. I've just checked out two repos (Are the addresses right?):
svn://tug.org/texlive/trunk/Master/texmf-dist/tex/generic/tex4ht http://svn.gnu.org.ua/sources/tex4ht/trunk/texmf/tex/generic/tex4ht They are different. The first one is older, although biblatex.4ht in it is newer (indeed of 2012-09-28-15:51). More importantly, when I copy 4ht files (including biblatex.4ht) from the second repo to my tex tree the error disappears. I don't know what's wrong. 2012/10/24 Karl Berry <[email protected]> > It seems that texlive contains an outdated package. > > I try to update the tex4ht package in TeX Live whenever CVR makes a > release in tex4ht svn.
