  • [X] I've updated hlint.dhall accordingly to my changes (add new rules for the new imports, remove old ones, when they are outdated, etc.).
  • [X] I've generated the new .hlint.yaml file (see this instructions).

General

• [X] I've updated the CHANGELOG with the short description of my latest changes.

FYI the Kowainik ecosystem sees very little activity. I personally work on emergency maintenance only, but you may find another maintainer who will review and accept a PR.

Thanks for the heads-up. Should I avoid using this library in the future then?

[tomjaguarpaw]

It will continue to be maintained so that it keeps working with newer releases of GHC, so no need to avoid using it on that basis. I wouldn't expected it to add many new features though.

Maybe @vrom911 can review this?

[drlkf]

Any chance we could have an update on this?

[tomjaguarpaw]

I'm afraid what I previously said still applies. The only maintenance being done on relude currently is the minimum necessary to keep it building with new GHCs.
