My two weeks end today, handing over to @sternenseemann again. I'm sure you're more aware of where we are than I am, right now, but a quick recap:
I guess we'll first need to see whether there are a few more central packages that should be fixed as dependencies of a few other maintained packages, but at some point we can start pinging all the maintainers to look into their packages, I guess? |

Since this package has nontrivial overrides for many versions, it's probably good to add an explicit job.
This partially reverts commit 36a316e. Reason for revert: GHC 9.14.2-rc1 breaks a lot of stuff due to breaking changes in core libs with few fixes for actual packages available at the moment. Thanks to release-haskell.nix (which isn't changed by this revert), we should have good visibility on the state of regressions either way.
Accidentally were in the jailbreaks section.
It's not clear to me whether it is concerning that this test suite fails.

This Merge
This PR is the regular merge of the
haskell-updatesbranch intostaging.This branch is being continually built and tested by hydra at https://hydra.nixos.org/jobset/nixpkgs/haskell-updates. You may be able to find an up-to-date Hydra build report at cdepillabout/nix-haskell-updates-status.
We roughly aim to merge these
haskell-updatesPRs at least once every two weeks. See the @NixOS/haskell team calendar for who is currently in charge of this branch.haskellPackages Workflow Summary
Our workflow is currently described in
pkgs/development/haskell-modules/HACKING.md.The short version is this:
haskell-updates(normally at the beginning of a merge window).haskell-updatesintostagingevery two weeks.mergeablejob is succeeding on hydra.maintainedpackage is still broken at the time of merge, we will only merge if the maintainer has been pinged 7 days in advance. (If you care about a Haskell package, become a maintainer!)More information about Haskell packages in nixpkgs can be found in the nixpkgs manual.
