* GHC now accepts type syntax in expressions as part of [GHC Proposal #281]
I feel like you buried the lede :)
Many thanks to everyone involved!

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.
