This is the thirtieth edition of our Haskell ecosystem 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 December 2025 to February 2026.
You can find the previous editions collected under the haskell-ecosystem-report tag.
Sponsorship
We offer Haskell Ecosystem Support Packages to provide commercial users with support from Well-Typed’s experts while investing in the Haskell community and its technical ecosystem including through the work described in this report. To find out more, read our announcement of these packages in partnership with the Haskell Foundation. We need funding to continue this essential maintenance work!
Many thanks to our Haskell Ecosystem Supporters: Standard Chartered, Channable and QBayLogic, as well as to our other clients who also contribute to making this work possible: Anduril, Juspay and Mercury; and to the HLS Open Collective for supporting HLS release management.
