9.2.8 is currently the recommended GHC in GHCup, but 9.2 branch won’t get a new release anymore. Stackage LTS-21.1 has moved to 9.4.5: LTS Haskell 21.1 (ghc-9.4.5) :: Stackage Server GHC developers expressed their feeling that 9.4.5 is a good release. It’s supported well by HLS too. What are your opinions? Are there still libraries lacking for 9.4.5? Are companies using it yet? Is 9.2.8 more comfortable still?

This release mainly introduces nightly support. Also see: https://www.haskell.org/ghcup/guide/#nightlies

Changelog

• Implement support for nightlies, wrt #824
• Fix GC with XDG dirs, fixes #810

How to use nightlies

Nightlies are just a nother release channel. Currently, only GHC supports nightlies, which are binary releases that are built every night from master.

To add the nightly channel, run:

ghcup config add-release-channel https://ghc.gitlab.haskell.org/ghcup-metadata/ghcup-nightlies-0.0.7.yaml

To list all nightlies from 2023, run:

ghcup list --show-nightly --tool=ghc --since=2023-01-01

Ways to install a nightly:

# by date
ghcup install ghc 2023-06-20
# by version
ghcup install ghc 9.7.20230619
# by tag
ghcup install ghc latest-nightly

This is mainly a bindist release.
