Zubin Duggal - 2025-09-10

The GHC developers are very pleased to announce the availability of the final release for GHC 9.10.3. Binary distributions, source distributions, and documentation are available at downloads.haskell.org and via GHCup.

GHC 9.10.3 is a bug-fix release fixing many issues of a variety of severities and scopes, including:

• Fix a number of crashes in the compiler frontend (#25960, #25004, #25056)
• Fix incorrect results in the NCG (#25601, #26061)
• Support for far jumps in the AArch64 NCG (#24648)
• A fix for a segfault in the RTS when running certain code involving STM (#26205)
• And many more!

A full accounting of these fixes can be found in the release notes. As always, GHC’s release status, including planned future releases, can be found on the GHC Wiki status.

We would like to thank Well-Typed, Tweag I/O, Juspay, QBayLogic, Channable, Serokell, 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 whose work comprise this release.

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