The version on CTAN seems still to be from 2008. I'll talk to CTAN about that.
Meanwhile, I have updated biblatex.4ht in TeX Live (as a special update of that one file) over the last couple months as CVR has made fixes. Perhaps I should tell Christian too, for MiKTeX. However, I don't seem to have any version from September. What I have is from July. CVR, could you send your latest to this list so everyone can see it, since I can't easily generate it right now? Paul: if biblatex.4ht isn't your problem, please send your actual input file. At least I don't have any way to guess what the problem might be out of the blue. Thanks, Karl
