Hi all,<br>
<br>
The GHC developers are very happy to announce the availability of the<br>
release cadidate of the 9.2.1 release. Binary distributions, source<br>
distributions, and documentation are available at<br>
<br>
     <a href="https://downloads.haskell.org/ghc/9.2.1-rc1" rel="noreferrer noreferrer noreferrer" target="_blank">https://downloads.haskell.org/ghc/9.2.1-rc1</a><br>
<br>
GHC 9.2 will bring a number of exciting features including:<br>
<br>
 * A native code generation backend for AArch64, significantly speeding<br>
   compilation time on ARM platforms like the Apple M1.<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>
Finally, thank you to Microsoft Research, GitHub, IOHK, the Zw3rk stake<br>
pool, Tweag I/O, Serokell, Equinix, SimSpace, and other anonymous<br>
contributors whose on-going financial and in-kind support has<br>
facilitated GHC maintenance and release management over the years.<br>
Moreover, this release would not have been possible without the hundreds<br>
of open-source contributors whose work comprise this release.<br>
<br>
As always, do give this release a try and open a [ticket] if you see<br>
anything amiss.<br>
<br>
Happy testing,<br>
<br>
