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

Congratulations! A minor question: Is the release date of 2nd February 2023 on the download page accurate?

I have added GHC 9.2.6 bindists to Stack’s default setup-info dictionary, and GHC 9.2.6 global hints, at GitHub - commercialhaskell/stackage-content: Content for the stackage.org site.

Thanks, it was a typo. It should be fixed now.
