Subject: [ANNOUNCE] GHC 9.12.1-alpha1 is now available
Message-ID: <2snpei5s6aapoanssr266h5idtgjcfsrojdiso6unuszkhdeih@7vyl6vfi2wzq>

The GHC developers are very pleased to announce the availability
of the first alpha release of GHC 9.12.1. Binary distributions, source
distributions, and documentation are available at [downloads.haskell.org][].


We hope to have this release available via ghcup shortly.

GHC 9.12 will bring a number of new features and improvements, including:

  * The new language extension [OrPatterns] allowing you to combine multiple
    pattern clauses into one.

  * The [MultilineStrings] language extension to allow you to more easily write
    strings spanning multiple lines in your source code.

  * Improvements to the OverloadedRecordDot extension, allowing the built-in
    `HasField` class to be used for records with fields of non lifted representations.

  * The [NamedDefaults] language extension has been introduced allowing you to
    define defaults for typeclasses other than `Num`.

  * More deterministic object code output, controlled by the `-fobject-determinism`
    flag, which improves determinism of builds a lot (though does not fully do so)
    at the cost of some compiler performance (1-2%). See #12935 for the details

  * GHC now accepts type syntax in expressions as part of [GHC Proposal #281].

  * ... and many more

A full accounting of changes can be found in the [release notes][].
As always, GHC's release status, including planned future releases, can
be found on the GHC Wiki [status][].

We would like to thank GitHub, IOG, the Zw3rk stake pool,
Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, the 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.

It worked for me on my M2 mac but only after uninstalling and reinstalling
Command Line Tools.

Hopefully the problem I had was unique to me. I got an error when I ran
./configure on my M2 mac:

Thanks Vanessa, it seems you had the same workaround: " remove and
reinstall XCode command-line tools."

Zubin

What OS were the install tests run on? I'm running on 15.0.1. I think 15.1
is coming at the end of the month around the same time as alpha 2,
hopefully 15.1 will be accompanied by a new version of XCode command-line
tools that resolves these issues.

Subject: [ANNOUNCE] GHC 9.8.3 is now available
Message-ID: <87bjzed972.fsf@smart-cactus.org>


The GHC developers are happy to announce the availability of GHC 9.8.3. Binary
distributions, source distributions, and documentation are available on the
[release] page.

This release is primarily a bugfix release the 9.8 series. These
include:

* Significantly improve performance of code loading via dynamic linking (#23415)
* Fix a variety of miscompilations involving sub-word-size FFI arguments
  (#25018, #24314)
* Fix a rare miscompilation by the x86 native code generator (#24507)
* Improve runtime performance of some applications of `runRW#` (#25055)
* Reduce fragmentation when using the non-moving garbage collector (#23340)
* Fix source links in Haddock's hyperlinked sources output (#24086)

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.

Happy compiling!

- Ben
