Hi Ben

It would be good if the status page (
https://ghc.haskell.org/trac/ghc/wiki/Status/GHC-8.2.1) could be updated
with what we will actually be getting. In particular, according to
https://ghc.haskell.org/trac/ghc/ticket/10074 Implement the 'Improved LLVM
Backend' proposal has been deferred to 8.4.1

Thanks
George
