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.
