    correctly on platforms lacking support for unaligned memory accesses
    (#21015, #20987).

  • Improvements to the compatibility story in GHC’s migration to the
    XDG Base Directory Specification (#20684, #20669, #20660)

  • Restored compatibility with Windows 7

  • A new -fcompact-unwind flag, improving compatibility with C++ libraries on
    Apple Darwin (#11829)

  • Introduction of a new flag, -fcheck-prim-bounds, enabling runtime bounds
    checking of array primops (#20769)

  • Unboxing of unlifted types (#20663)

  • Numerous improvements in compiler performance.

  • Many, many others. See the release notes for a full list.

As some of the fixed issues do affect correctness users are encouraged to
upgrade promptly.

Finally, thank you to Microsoft Research, GitHub, IOHK, the Zw3rk stake
pool, Tweag I/O, Serokell, Equinix, SimSpace, and other anonymous
contributors whose on-going financial and in-kind support has
facilitated GHC maintenance and release management over the years.
Moreover, this release would not have been possible without the hundreds
of open-source contributors whose work comprise this release.

As always, do open a ticket if you see anything amiss.

Happy compiling,
