Hello,

The new biblatex version (\def\abx at version{3.8a}) breaks tex4ht because
tex/generic/tex4ht/biblatex.4ht performs tests like :
\ifdim\abx at version pt< 3pt
or \ifdim\abx at version pt< 3.3pt
which break with a "Illegal unit of measure" error.

Should it  be fixed in biblatex or tex4ht ?

Regards,
Rémy.
