GHC Internals Changed

Hi, It seems that GHC's API interface has changed between 6.6 and 6.8. Most notably, JustTypecheck and GHC.dropForAlls are no longer in scope. Are the changes documented anywhere? The notes on the hackage commentary still seem to point to the previous API internals. http://hackage.haskell.org/trac/ghc/wiki/Commentary/Compiler/API Kind regards, Chris.
