Hope that enough copies are sold that O'Reilly lets us make a 2nd
edition when things change? :-)
More seriously, you do the best you can. We tried to mostly write
about things that are in the libraries that ship with GHC. There are
some exceptions, such as HDBC and gtk2hs. But these things happen in
any language, and you publish errata, or a new edition.
We've already been bitten by this, and we're not even in production
yet. The regex library included with GHC 6.8.3 can be used in a
[String] context, but the newer regex library on Hackage (which is
shipped by Debian) can't. Doh.

We haven't specifically discussed that, but in general, doing a book
is a *lot* of work, and I suspect all three of us will be wanting to
take a break from book-writing or -maintaining activities for a bit
after O'Reilly starts cutting down trees on our behalf.
That said, we're still maintaining all the infrastructure for the
project, so we could go and update things at any time.
