This release is primarily a bugfix release addressing many issues
found in the 9.8 series. These include:

  • A fix for a bug where certain warnings flags were not recognised (#24071)
  • Fixes for bugs in the renamer and typechecker (#24084, #24134, #24279, #24083)
  • Fixes for bugs in the simplifier and code generator (#24160, #24242, #23628, #23659, #24160, #23862, #24295, #24370)
  • Fixes for some memory leaks in GHCi (#24107, #24118)
  • Improvements to error messages (#21097, #16996, #11050, #24196, #24275, #23768, #23784, #23778)
  • A fix for a recompilation checking bug where GHC may miss changes in
    transitive dependencies when deciding to relink a program (#23724).
  • And many more fixes

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.

Enjoy!

A minor thing: I experience a ‘404 Not Found’ for URL https://downloads.haskell.org/~ghc/9.8.2/ (but not for Index of /ghc/9.8.2/).

I have updated Stack’s default setup-info dictionary for these binary distributions, and added GHC 9.8.2’s global hints to global-hints.yaml .
