of the first alpha release of GHC 9.12.1. Binary distributions, source<br>
distributions, and documentation are available at [<a href="http://downloads.haskell.org" rel="noreferrer" target="_blank">downloads.haskell.org</a>][].<br>
<br>
<br>
We hope to have this release available via ghcup shortly.<br>
<br>
GHC 9.12 will bring a number of new features and improvements, including:<br>
<br>
* The new language extension [OrPatterns] allowing you to combine multiple<br>
pattern clauses into one.<br>
<br>
* The [MultilineStrings] language extension to allow you to more easily write<br>
strings spanning multiple lines in your source code.<br>
<br>
* Improvements to the OverloadedRecordDot extension, allowing the built-in<br>
`HasField` class to be used for records with fields of non lifted representations.<br>
<br>
* The [NamedDefaults] language extension has been introduced allowing you to<br>
define defaults for typeclasses other than `Num`.<br>
<br>
* More deterministic object code output, controlled by the `-fobject-determinism`<br>
flag, which improves determinism of builds a lot (though does not fully do so)<br>
at the cost of some compiler performance (1-2%). See #12935 for the details<br>
<br>
* GHC now accepts type syntax in expressions as part of [GHC Proposal #281].<br>
<br>
* ... and many more<br>
<br>
A full accounting of changes can be found in the [release notes][].<br>
As always, GHC's release status, including planned future releases, can<br>
be found on the GHC Wiki [status][].<br>
<br>
We would like to thank GitHub, IOG, the Zw3rk stake pool,<br>
Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, the Haskell<br>
Foundation, and other anonymous contributors whose on-going financial<br>
and in-kind support has facilitated GHC maintenance and release<br>
management over the years. Finally, this release would not have been<br>
possible without the hundreds of open-source contributors whose work<br>
comprise this release.<br>
<br>
As always, do give this release a try and open a [ticket][] if you see<br>
anything amiss.<br>
