The main thing is porting to ghc 6.8 -- which means the new (*faster*) lazy bytestring representation, and the smp parallel quickcheck driver for the testsuite (it'll use N cores, watch the jobs migrate around).

Binary 0.4 seems to require bytestring 0.9, the library formerly known as fps. I just want to mention it, as most network resources (as found by Google) only have discoverd fps 0.7, which is not going to work.

(Oh, and yes, it's at darcs.haskell.org/bytestring/ )

It'd be nice - since I know you're at it anyway :-) - if hackage/cabal would have some support for backwards compatibility. I know GHC 6.8 is the thing to get, but some of us still install what comes with our distribution, so I hope 6.6.1 still will be supported.

Normally this is farily easy to do, with cabal configurations. (See bytestring's .cabal file for example). However, the binary internals changed in such a way that it wasn't worth preserving backwards buildability. Instead, you should use binary 0.3 with ghc 6.6 libs A released version of bytestring 0.9 will be on hackage shortly. -- Don
