One difference between 6.8.1 and 6.8.2 that I see is in running "runhaskell Setup.hs haddock" with Haddock 0.8 on Windows XP.  Haddock is no longer able to resolve the names from the standard libraries. 

Running Haddock for Xyz-0.1...
Warning: Xyz: the following names could not be resolved:
    FilePath Show Eq String Maybe Bool Char Int

Thanks,
