I had a niggling worry last night, and it turned out to be an actual issue, filed at: https://github.com/haskell/haskell-platform/issues/251 Note that this is a serious issue; it will make Stack essentially unusable for anyone using HP Minimal on Windows and trying to use GHC 8. Regardless of any other discussions around changing the download page, I'd request that this bug be resolved first. Not only will it cause user problems, but will potentially cause a significant maintenance burden for Stack (I heard from Stack maintainers in the past that a similar situation existed with GHC for Mac OS X shipping an old buggy Stack version). (Sorry if a duplicate, I mistakenly sent from the wrong address previously.)
