Hi all, The GHC developers are very happy to announce the availability of the release cadidate of the 9.2.1 release. Binary distributions, source distributions, and documentation are available at
https://downloads.haskell.org/ghc/9.2.1-rc1
GHC 9.2 will bring a number of exciting features including:
* A native code generation backend for AArch64, significantly speeding
compilation time on ARM platforms like the Apple M1.
* Many changes in the area of records, including the new
`RecordDotSyntax` and `NoFieldSelectors` language extensions, as well
as Support for `DuplicateRecordFields` with `PatternSynonyms`.
* Introduction of the new `GHC2021` language extension set, giving
users convenient access to a larger set of language extensions which
have been long considered stable.
* Merge of `ghc-exactprint` into the GHC tree, providing infrastructure
for source-to-source program rewriting out-of-the-box.
* Introduction of a `BoxedRep` `RuntimeRep`, allowing for polymorphism
over levity of boxed objects (#17526)
* Implementation of the `UnliftedDataTypes` extension, allowing users
to define types which do not admit lazy evaluation ([proposal])
* The new [-hi profiling] mechanism which provides significantly
improved insight into thunk leaks.
* Support for the `ghc-debug` out-of-process heap inspection library
[ghc-debug]
* Support for profiling of pinned objects with the cost-centre profiler
(#7275)
* Introduction of Haddock documentation support in TemplateHaskell (#5467)
Finally, thank you to Microsoft Research, GitHub, IOHK, the Zw3rk stake
pool, Tweag I/O, Serokell, Equinix, SimSpace, and other anonymous
contributors whose on-going financial and in-kind support has
facilitated GHC maintenance and release management over the years.
Moreover, 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.
Happy testing,
- Ben
