Zubin Duggal - 2023-02-10

The GHC developers are happy to announce the availability of GHC 9.2.6. Binary distributions, source distributions, and documentation are available at

This release is primarily a bugfix release addressing a few issues found in 9.2.5. These include:

  • Fixes for a number of simplifier issues typically resulting in compiler panics (#22491, #22482, #19824, #22718, #22662, #22039).
  • Fix for a simplifier regression in 9.2.5 that could impact runtime performance when compiling with optimisations due to duplication of expensive work (#22425).
  • Various stability improvments and bug fixes for the non moving and parallel GCs (#22528, #20221, #22264, #22327, #22929, #22927, #22929, #22930).
  • Allow certain keywords which can be used as variable names with -XOverloadedRecordDot (#20723).
  • Improvements to typechecker performance for modules with holes in type signatures (#14766)
  • Bump gmp-tarballs to a version which doesn’t use the reserved x18 register on AArch64/Darwin systems, and also has fixes for CVE-2021-43618 (#22497, #22789).
  • … and a few more. See the release notes for a full accounting.

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,

  • Zubin
