fixed from the texlive side.
Are there any plans to update biber to a version compatible with

Regarding tex4ht: I push all fixes we make in the tex4ht repository to
TeX Live; the latest was a few days ago. Michal Hoftich has been
regularly responding to bug reports in tex4ht, for which I am greatly
thankful. -k
