When will this new update become part of tex4ht
included in texlive itself?
I've installed the changes in TeX Live now; assuming tonight's update
goes ok, you should be able to get it with tlmgr in a day or two. Not
that there's any need for you to do so since you already installed the
files by hand.
how would one know if this fix is there or not?
By looking at the \version date at the top of multicol.4ht and html4.4ht.
Best,
Karl
