[Haskell] [ANNOUNCE] GHC 9.2.8 released
by Zubin Duggal 26 May '23

26 May '23

The GHC developers are happy to announce the availability of GHC 9.2.8. Binary distributions, source distributions, and documentation are available at [downloads.haskell.org](https://downloads.haskell.org/ghc/9.2.8). This release is primarily a bugfix release addressing one issue found in 9.2.7: - Fix a bug with RTS linker failing with 'internal error: m32_allocator_init: Failed to map' on newer Linux kernels (#19421). 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 [ticket]: https://gitlab.haskell.org/ghc/ghc/-/issues/new [release notes]: https://downloads.haskell.org/~ghc/9.2.8/docs/html/users_guide/9.2.8-notes.…

[ANNOUNCE] GHC 9.6.2 is now available
by Ben Gamari 23 May '23

23 May '23

The GHC developers are happy to announce the availability of GHC 9.6.2. Binary distributions, source distributions, and documentation are available at https://downloads.haskell.org/ghc/9.6.2 This release is primarily a bug-fix release addressing a few issues found in 9.6.2. These include: * a number of simplifier and specialisation issues (#22761, #22549) * A bug resulting in crashes of programs using the new ``listThreads#`` primop (#23071). * A compiler crash triggered by certain uses of quantified constraints (#23171) * Various bugs in the Javascript backend have been fixed (#23399, #23360, #23346) * A missing write barrier in the non-moving collector's handling of selector thunks, resulting in undefined behavior (#22930). * The non-moving garbage collector's treatment of weak pointers has been revamped which should allow more reliable finalization of ``Weak#`` closures (#22327) * The non-moving garbage collector now bounds the amount of marking it will do during the post-marking stop-the-world phase, greatly reducing tail latencies in some programs (#22929) 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.
