On behalf of the Haskell Platform team, I'm happy to announce the release of Haskell Platform 8.4.2 Now available at https://www.haskell.org/platform/ This includes GHC 8.4.2, cabal-install 2.2.0.0, and stack 1.7.1, all with substantial improvements since the last platform release. A full list of contents is available at https://www.haskell.org/platform/contents.html Thanks to all the contributors to this release, thanks to all the package and tool maintainers and authors, and a big thanks to the GHC team for all their hard work. There are (still) currently no 32 bit Windows builds available. We're looking into the issues preventing us from building an installer for that platform. The components all appear to work individually in such a case, and can be installed separately by users who so desire. A list of new GHC changes is available at: https://ghc.haskell.org/trac/ghc/blog/ghc-8.4.1-released and https://ghc.haskell.org/trac/ghc/blog/ghc-8.4.2-released A list of cabal changes is available at: https://hackage.haskell.org/package/cabal-install-2.2.0.0/changelog The cabal documentation page is at: https://www.haskell.org/cabal/users-guide/ A list of stack changes is at: https://docs.haskellstack.org/en/stable/ChangeLog/#v171 The stack documentation page is at: https://docs.haskellstack.org/en/stable/README/ Happy Haskell Hacking all, Gershom
