<br>
The GHC developers are very happy to announce the availability of the<br>
first alpha release in the 9.2.1 series. Binary distributions, source<br>
distributions, and documentation are available at<br>
<br>
<a href="https://downloads.haskell.org/ghc/9.2.1-alpha1" rel="noreferrer" target="_blank">https://downloads.haskell.org/ghc/9.2.1-alpha1</a><br>
<br>
GHC 9.2 will bring a number of exciting features including:<br>
<br>
* Many changes in the area of records, including the new<br>
`RecordDotSyntax` and `NoFieldSelectors` language extensions, as well<br>
as Support for `DuplicateRecordFields` with `PatternSynonyms`.<br>
<br>
* Introduction of the new `GHC2021` language extension set, giving<br>
users convenient access to a larger set of language extensions which<br>
have been long considered stable.<br>
<br>
* Merge of `ghc-exactprint` into the GHC tree, providing infrastructure<br>
for source-to-source program rewriting out-of-the-box.<br>
<br>
* Introduction of a `BoxedRep` `RuntimeRep`, allowing for polymorphism<br>
over levity of boxed objects (#17526)<br>
<br>
* Implementation of the `UnliftedDataTypes` extension, allowing users<br>
to define types which do not admit lazy evaluation ([proposal])<br>
<br>
* The new [-hi profiling] mechanism which provides significantly<br>
improved insight into thunk leaks.<br>
<br>
* Support for the `ghc-debug` out-of-process heap inspection library<br>
[ghc-debug]<br>
<br>
* Support for profiling of pinned objects with the cost-centre profiler<br>
(#7275)<br>
<br>
* Introduction of Haddock documentation support in TemplateHaskell (#5467)<br>
<br>
In addition, the final 9.2.1 release will bring a new native code<br>
generator for ARM, providing fast, first-class for Haskell on Apple<br>
ARM hardware [apple-m1], although this functionality is not yet<br>
present in this alpha.<br>
<br>
As always, do give this a try and open a [ticket] if you see anything amiss.<br>
<br>
Happy testing,<br>
<br>
