I always love comments like this one, taken from an htdig mailing list:

There are quite a few bugs that remain to be resolved, plus some
remaining performance issues. The latter will require some work to
overcome and will probably involve rewriting large parts of htsearch
(this will also give additional features).
Emphasis added with regard to a large rewrite that will also give additional features, but um, given their time table (ten months between point releases of their beta) so far, it could be quite a while before a non beta htDig is released.
