Upgrading packages
A list of things that need updating when porting packages to newer library/cabal versions.
If you maintain a Haskell package this is for you. For older versions of this document:
Updating to GHC 7.0
When upgrading to GHC 7.0, any of your packages that worked against the base-3 library will need to be updated to the base-4.
Wanted - catering to GHC versions
How do I configure Cabal to use different GHC options depending on GHC version? E.g. using -fno-warn-unused-bind is convenient for certain GHC versions, but breaks compatibility with older ones.
(This is a stub, since the previous version was so out-of-date. Please help by adding useful content.)
