Have array and reference types and primos been updated to be
BoxedRep-polymorphic, or is it still just expensive scaffolding?

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
