Haskell GHC 9.6 and Stackage LTS 22
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.

Current status
- Targeted release: Fedora Linux 40
- Last updated: 2023-12-17

- 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.
GHC 9.6.3 is the current recommended version of GHC with various enhancements and fixes (see the release notes linked in the Documentation section for more details).
Scope
- Proposal owners:
- update rawhide ghc9.4 is build against itself
- rebase ghc to 9.6.3
- refresh packagings with the latest cabal-rpm release if needed
- update packages to latest Stackage LTS 22 versions using cabal-rpm
- build all the packages in a Koji sidetag repo in dependency order using fbrnch
- push the sidetag through Bodhi to rawhide
- Other developers: no actions should be needed
- Release engineering: #Releng issue number
- Policies and guidelines: N/A (not needed for this Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with Community Initiatives: N/A
Upgrade/compatibility impact
Any dropped packages will have obsoletes added. Otherwise there should not be any direct upgrade impact.
Users' Haskell projects will get built with ghc-9.6 when they next build them and might need some minor code tweaks (see the release notes linked below).
