Thanks for the contribution!

CI fails in the usual place: you have to update that hash whenever add an extension.

This time it failed to a usual GHA outage, so I've restarted failed jobs.

@tek: is this ready for merge? If so, could you rebase, remove the Draft mark and set the review_needed label? (Please let me know if any of these doesn't work.)

[tek]

the GHC MR is still not approved, though Vlad is pushing for it, so might be a few days.
I only rebased for now.

[tek]

ok I guess this doesn't have to wait for the GHC MR to be merged!

[tek]

@Mikolaj I have no label permissions, though

[Mikolaj]

How about now?

[tek]

thanks!

[tek]

hey @Mikolaj, would you be so kind and merge this now?

[ulysses4ever]

Feel free to proceed with the labels, as described here: https://github.com/haskell/cabal/blob/master/CONTRIBUTING.md#github-pull-request-conventions

@tek: apparently, a conflict with the master branch popped up at the last moment. Once you resolve it, merging should resume (probably immediately, but at worst in 2 days).
