GHC 9.8.4 is now available

Ben Gamari - 2024-12-02

The GHC developers are happy to announce the availability of GHC 9.8.4. Binary distributions, source distributions, and documentation are available on the release page.

This release is a small release fixing a few issues noted in 9.8.3, including:

Update the filepath submodule to avoid a misbehavior of splitFileName under Windows.
Update the unix submodule to fix a compilation issue on musl platforms
Fix a potential source of miscompilation when building large projects on 32-bit platforms
Fix unsound optimisation of prompt# uses

A full accounting of changes can be found in the release notes. As some of the fixed issues do affect correctness users are encouraged to upgrade promptly.

We would like to thank Microsoft Azure, GitHub, IOG, the Zw3rk stake pool, Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, 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.

Happy compiling!
