It was just pointed out in #haskell by mreh that the version of xmonad-contrib currently released on Hackage fails to build, since it does not specify version bounds on its mtl dependency, but fails to build with mtl-2, since XMonad.Utils.CustomKeys uses the Reader constructor and HintedGrid uses State. This has since been fixed; the darcs version of xmonad-contrib builds fine with mtl-1 and mtl-2. However, it's poor form to have the released version fall over if you just do 'cabal install xmonad-contrib'. Concretely, I propose that we do a spot bugfix release of just the 0.9.1 tag + the patch that fixed the mtl-2 incompatibility: Mon Nov 15 18:26:54 EST 2010 Adam Vogt <vogt.adam@gmail.com> * Compatibility with mtl-1 and mtl-2 The other option would be to do a point release of whatever is currently in darcs, but that would be more work to do properly. I'm happy to do the work to make this happen, I just wanted to hear some reactions first. -Brent
