GHC 9.12.2 is now available

Ben Gamari - 2025-03-14

The GHC developers are happy to announce the release of GHC 9.12.2. Binary distributions, source distributions, and documentation are available at downloads.haskell.org.

We hope to have this release available via ghcup shortly. This is a small release fixing a critical code generation bug, #25653, affecting some subword division operations.

As always, GHC’s release status, including planned future releases, can be found on the GHC Wiki status.

We would like to thank IOG, the Zw3rk stake pool, Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, the Haskell Foundation, and other anonymous contributors whose on-going financial and in-kind support has facilitated GHC maintenance and release management over the years. Finally, this release would not have been possible without the hundreds of open-source contributors who contribute their code, tickets, and energy to the GHC project.

As always, do give this release a try and open a ticket if you see anything amiss.
