• The ghc version condition was changed to '>= 9.10.2', but the changelog indicates support for ghc-9.12. Please verify that this lower bound is intentional and update the documentation accordingly.

if impl (ghc >= 9.10.2)

Hiya, I wanted to ask why the sub-libraries are renamed? IIUC, there's no way in cabal to say "depend on io-classes:strict-mvar ^>= 1.7 or depend on io-classes:io-classes-strict-mvar ^>=1.8". So changing a sub-library name means a dependent package could never support both the old and new sublibrary. It's kind of similar to re-uploading a package to Hackage under a new name, and deprecating the old one. There'd also be no way to support both the old and new package

Feel free to do with this info what you want of course -- maybe you've already considered what I said. I wanted to point it out just in case

Because the support for named sub-libraries in haskell.nix is poor at this stage, e.g. io-classes:mtl can be confused with mtl :/.

[jorisdral]

I had a feeling that was the reason, thanks for the info!

With input-output-hk/haskell.nix#2363 we might not need the new prefixes.

The issue is fixed, I dropped the prefixes 😄.

Except the MonadTraceMVar (IOSim s) instance, all changes are removing only Pragmas so it looks fine. The changes there also look reasonable.
