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!

- Ben
