[ANNOUNCE] GHC 9.4.3 is now available
by Ben Gamari 08 Nov '22

08 Nov '22

The GHC developers are happy to announce the availability of GHC 9.4.3. Binary distributions, source distributions, and documentation are available at downloads.haskell.org: https://downloads.haskell.org/ghc/9.4.3 This release is primarily a bugfix release addressing a few issues found in 9.4.2. These include: * An issue where recursively calls could be speculatively evaluated, resulting in non-termination (#20836) * A code generation issue in the AArch64 native code generator backend resulting in incorrect runtime results in some circumstances (#22282) * A crash on Darwin when running executables compiled with IPE support (#22080) * A long-standing interface-file determinism issue where full paths would leak into the interface file (#22162) * A bug in the `process` library where file handles specified as `NoStream` would still be usable in the child (process#251) Note that, as GHC 9.4 is the first release series where the release artifacts are all generated by our new Hadrian build system, it is possible that there will be packaging issues. If you enounter trouble while using a binary distribution, please open a [ticket]. Likewise, if you are a downstream packager, do consider migrating to [Hadrian] to run your build; the Hadrian build system can be built using `cabal-install`, `stack`, or the in-tree [bootstrap script]. See the accompanying [blog post] for details on migrating packaging to Hadrian. We would also like to emphasize that GHC 9.4 must be used in conjunction with Cabal-3.8 or later. This is particularly important for Windows users due to changes in GHC's Windows toolchain. 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 Haskelling, - Ben [ticket]: https://gitlab.haskell.org/ghc/ghc/-/issues/new [bootstrap script]: https://gitlab.haskell.org/ghc/ghc/-/blob/e2520df3fffa0cf22fb19c5fb872832d1… [Hadrian]: https://gitlab.haskell.org/ghc/ghc/-/blob/e2520df3fffa0cf22fb19c5fb872832d1… [blog post]: https://www.haskell.org/ghc/blog/20220805-make-to-hadrian.html

Hi all, Today we will be doing some maintenance on gitlab.haskell.org to address #22418. I can't yet say precisely when the outage will begin but I do expect there to be one. I will try to provide at least 30 minutes notice. Cheers, - Ben
