The GHC developers are very happy to at announce the availability of GHC 9.2.2. Binary distributions, source distributions, and documentation are available at downloads.haskell.org: https://downloads.haskell.org/ghc/9.2.2 This release includes many bug-fixes and other improvements to 9.2.1 including: * A number of bug-fixes in the new AArch64 native code generator * Fixes ensuring that the `indexWord8ArrayAs*#` family of primops is handled 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, - Ben [ticket]: https://gitlab.haskell.org/ghc/ghc/-/issues/new [release notes]: https://downloads.haskell.org/ghc/9.2.2/docs/html/users_guide/9.2.2-notes.h…
