Hi, when the Creators Update finally hits Windows 10 stable on April 11th (next week), every currently available GHC will be broken by it. See [1] for the previous discussion, [2] and [3] for the tickets discussing this. From what I read on the GHC 8.2 status wiki page, there might be an interval of some weeks where it will not be possible to compile a Haskell program on any up-to-date Windows 10 installation. I just wanted to raise awareness and offer myself to do guided grunt work (if there is any) to push out a hotfix/inplace patch release for GHC 8.0.2. Greetings, Sebastian [1] http://haskell.1045720.n5.nabble.com/FW-GHC-on-Windows-10-15019-td5853491.ht...
