9.4.1 release tracking

This is the template to be used to create release tracking tickets. Copy this into a new issue and fill in the TODOs. Those items marked with major-only can be ignored for minor releases.

This is the release checklist for the TODO milestone. See #16816 for the template that this was derived from.

Pre-fork checklist (major-only)

When forking a new release branch for a new major release series (e.g. ghc-9.0), please check the following:

  • Verify that haddock's development branch (namely the branch corresponding to GHC's previous major release, e.g. ghc-8.10) has been merged into ghc-head.
  • Remove the release notes for the previous release (e.g. docs/users_guide/8.6.*-notes.rst)
  • Create the new branch: git branch ghc-9.0
  • In the new branch bump the version number in configure.ac to, e.g., 9.0
  • In master bump the version number to that of the next development series, e.g., 9.1
  • Tag this master commit as, e.g., ghc-9.1-start
  • Push all of the above tags and branches
  • After forking remove release notes from master and start a new set of release notes for the next release
