The GHC developers are happy to announce the availability of GHC 9.8.3. Binary distributions, source distributions, and documentation are available on the release page.

This release is primarily a bugfix release the 9.8 series. These include:

Significantly improve performance of code loading via dynamic linking (#23415)
Fix a variety of miscompilations involving sub-word-size FFI arguments (#25018, #24314)
Fix a rare miscompilation by the x86 native code generator (#24507)
Improve runtime performance of some applications of runRW# (#25055)
Reduce fragmentation when using the non-moving garbage collector (#23340)
Fix source links in Haddock’s hyperlinked sources output (#24086)

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!
