Since there wasn't any new release for more than one year I would also like
to ask you whether this package is still maintanted.
It's still maintained, although I'm too busy to spend a lot of time on
it right now.  Maybe next year...

But it would still be nice if there would be a new release. With some
bugfixes for example. It does not need to have all new features. And
it would show that this module is still maintained.
That is a bit harsh... And if Sam was to put out a release with bugfixes, what would it contain?

You have the source code to H::T, you could always do produce a release yourself - Sam may even take the to code to make it official...
Also, there are a few of us here that maintain modified versions of H::T, each of which enhance H::T in some way - you could always choose to use those instead.
