This is a proposed Change for Fedora Linux.
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.

Summary

Update the GHC Haskell compiler from major version 9.4 to 9.6, and Haskell packages will be updated from Stackage LTS 21 to LTS 22 versions.

Owner


Current status

  • Targeted release: Fedora Linux 40
  • Last updated: 2023-12-17
  • [<will be assigned by the Wrangler> devel thread]
  • FESCo issue: <will be assigned by the Wrangler>
  • Tracker bug: <will be assigned by the Wrangler>
  • Release notes tracker: <will be assigned by the Wrangler>

Detailed Description

For Fedora 40, the main GHC Haskell compiler package will be updated from version 9.4.5 to the latest stable 9.6.3 or newer bugfix release (rebasing the ghc package with the ghc9.6 package). Along with this, Haskell packages in Stackage (the stable Haskell source package distribution) will be updated from the versions in LTS 21 to latest LTS 22 release. Haskell packages not in Stackage will be updated to the latest appropriate version in the upstream Hackage package repository.

Feedback

Benefit to Fedora

Fedora users will have the latest stable Haskell compiler release, package tools, and current Haskell packages from latest Stackage LTS.
