It collects the 7 or so known issues that break code with GHC 6.10.
i've quickly tried to compile my app with 6.10 (using base4). all the problems i got was due to exception handling. catch, finally, throwIO doesn't work
added to wiki
The fix for exception handling and friends is to add a dependency on base-3,
http://haskell.org/haskellwiki/Upgrading_packages#Adding_base-3_constraints
If you build your app with cabal-install, it will work this out for you, otherwise, you need to add something like
--constraint="base<4"
if you use runhaskell, or
--package base-3.0.3.0
if you use ghc --make.
