Please test as much as possible; bugs are much cheaper if we find them before the release!
Could you please have a look at the documentation issues in the Windows installer before release? Points 4-6 in: http://hackage.haskell.org/trac/ghc/ticket/4292 (documentation links in haddock and ghc-pkg no longer match current directory layout) I'm somewhat surprised that noone else has tripped over these in the current release (though I recall occasional unspecified complaints about documentation links on GHC and Haskell Platform mailing lists, so perhaps there are related tickets?). Also, assuming that Simon's patch fixes http://hackage.haskell.org/trac/ghc/ticket/4332 (can't redirect the output of individual GHCi commands anymore; again, on Windows) it would be nice/important to have that merged into the release, as I know of no workaround.
