Re: [Haskell-cafe] [ANNOUNCE] GHC 9.2.1 now available

It seems the OS X distribution is missing profiling libs, details at
https://gitlab.haskell.org/ghc/ghc/-/issues/20707 but that's basically
the whole story :)

If you are on Fedora you can now install ghc-9.2.1 with:

sudo dnf --enablerepo=updates-testing-modular module install ghc:9.2/default

Great news!

Install works on mac os if you do

xattr -rc .

before doing

make install

The mail didn't mention that nor is it mentioned in the INSTALL file.

I thought this had been fixed. I guess I'm mistaken or this is only an
issue for me.

Thanks again for getting this out! There's a lot of great stuff in the
release.

Cheers
George

[ANNOUNCE] GHC 9.2.1 now available

[Ben Gamari]

Hi all,

The GHC developers are very happy to at long last announce the
availability of GHC 9.2.1. Binary distributions, source distributions,
and documentation are available at

https://downloads.haskell.org/ghc/9.2.1

GHC 9.2 brings 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.

 * Merging 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]

 * Significant improvements in the bytecode interpreter, allowing more
   programs to be efficently run in GHCi and Template Haskell splices.

 * Support for profiling of pinned objects with the cost-centre profiler
   (#7275)

 * Faster compilation and a smaller memory footprint

 * 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 open a [ticket] if you see anything amiss.

Happy testing,

- Ben
