Subject: [ANNOUNCE] GHC 9.12.1-rc1 is now available
MIME-Version: 1.0

The GHC developers are very pleased to announce the availability
of the release candidate for 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].

  * The WASM backend now has support for TemplateHaskell.

  * ... 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.

Cheers,
Zubin
