On behalf of the Haskell Platform team, I'm happy to announce the release of Haskell Platform 8.4.3 Now available at https://www.haskell.org/platform/ This includes GHC 8.4.3, cabal-install 2.2.0.0, and stack 1.7.1. A full list of contents is available at https://www.haskell.org/platform/contents.html Outside of the update of the GHC to 8.4.3, the only substantive change in this release is to the new version of the primitive library, which includes a range of fixes and improvements. The list of GHC changes is available at: https://ghc.haskell.org/trac/ghc/blog/ghc-8.4.3-released And the list of changes to Primitive is available at: http://hackage.haskell.org/package/primitive-0.6.4.0/changelog 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. Happy Haskell Hacking all, Gershom
