Release 2.3.0.0

[wz1000]

• Prepare release 2.3.0.0
• Switch darwin release CI to nix

Checklist

• check ghcup supports new GHC releases if any
• set the supported GHCs in workflow file .github/workflows/release.yaml
  • There is currently a list of GHC versions for each major platform. Search for ghc: [ to find all lists.
  • Look for TODO: to find locations that require extra care for GHC versions.
• check all plugins still work if release includes code changes
• bump package versions in all *.cabal files (same version as hls)
  • HLS uses lockstep versioning. The core packages and all plugins use the same version number, and only support exactly this version.
    • Exceptions:
      • hie-compat requires no automatic version bump.
      • shake-bench is an internal testing tool, not exposed to the outside world. Thus, no version bump required for releases.
  • For updating cabal files, the following script can be used:

    • # Update all `version:` fields
      sed -ri "s/^version:( +)2.2.0.0/version:\12.3.0.0/" **/*.cabal
      # Update all constraints expected to be in the form `== <version>`.
      # We usually don't force an exact version, so this is relatively unambiguous.
      # We could introduce some more ad-hoc parsing, if there is still ambiguity.
      sed -ri "s/== 2.2.0.0/== 2.3.0.0/" **/*.cabal

    • It still requires manual verification and review

Cirrus CI does not seem to be working. I will do the release without freebsd binaries.

[michaelpj]

Should we merge this since it looks like you released?

Readthedocs doesn't seem updated?
