Maybe. I saw "Version 1.1", so I decided it's newer. Understandable, but not correct. I made up "Version 1.1" when I first started working on tex4ht, then we decided that the date-based versions are better.
The version of biblatex.4ht is 2012-09-28-15:51.
Thanks for confirming. And now, CVR has just released a new version
{2012-10-25-14:56}, and I've updated TL. Can you check that please?
(Probably no help, but ...)
