I think this points out the benefit (or even the need), given the fast-paced evolution of Haskell and its libraries as a whole, of an evolving online supplement to your book, minimally with errata and code, but also (as publisher resources permit) with intermittently updated appendices on still-evolving technologies and (most risky of all), advice on the best tool or library of various tasks (e.g. UI) as a function of risk and programmer experience. I think this approach is the surest defense against shelf-rot. Dan Bryan O'Sullivan wrote:

Covering reactive programming would indeed be interesting.
I agree. However, we have no plans to cover this topic. I don't believe any of us has used FRP, and my impression of it as an approach is that it's not yet cooked. We already have our hands and TOC full covering well-established topics, never mind tracking the leading edge of research. (For similar reasons, we won't be writing about ndp, even though it's got a lot more obvious crowd appeal.)
