This release updates the Haskell programming language stack:
The Glasgow Haskell Compiler (GHC) updates from version 8.4 to 8.6.
The Stackage platform updates from version 12 LTS to 13 LTS.
Additionally, Haskell documentation and profiling libraries are now provided by separate packages. As a result, you can now install a smaller Haskell development environment.
For more information about GHC 8.6, see the release notes: https://downloads.haskell.org/~ghc/8.6.5/docs/html/users_guide/8.6.1-notes.html.
