This is the twenty-third edition of our GHC activities report, which describes the work Well-Typed are doing on GHC, Cabal, HLS and other parts of the core Haskell toolchain. The current edition covers roughly the months of March to May 2024. You can find the previous editions collected under the ghc-activities-report tag.


We are delighted to offer new Haskell Ecosystem Support Packages to provide commercial users with access to Well-Typed’s experts while investing in the Haskell community and its technical ecosystem. If your company is using Haskell, read more about our offer, or get in touch with us today, so we can help you get the most out of the toolchain, and continue our essential maintenance work.

Many thanks to our existing sponsors who make this work possible: Anduril and Juspay. In addition, we are grateful to Mercury for funding specific work on improved performance for developer tools on large codebases, to the Sovereign Tech Fund for funding work on Cabal, and to the HLS Open Collective for funding work on HLS. Of course, Haskell tooling is a large community effort, of which Well-Typed’s contributions are just one part. We are immensely grateful to everyone contributing to the Haskell ecosystem!
