Apologies, I thought I had tested, but I copied without the 'module'
command, it should be:

$ sudo dnf --enablerepo=updates-testing-modular module install
ghc:9.0/default

Alternatively you can run, eg:

$ sudo dnf --enablerepo=updates-testing-modular module enable ghc:9.0
$ sudo dnf --enablerepo=updates-testing-modular install ghc

etc

It should go stable in about a week.

Thanks, Jens

Hi Jens,

fedora newbie here. Not sure what I'm doing wrong, but it's not working
on f33/amd64 here:

[karel@localhost ~]$ sudo dnf update
[sudo] password for karel:
Last metadata expiration check: 0:00:33 ago on Mon 08 Feb 2021 05:53:17
PM CET.
Dependencies resolved.
Nothing to do.
Complete!
[karel@localhost ~]$ sudo dnf --enablerepo=updates-testing-modular
install ghc:9.0/default
Last metadata expiration check: 0:00:49 ago on Mon 08 Feb 2021 05:53:17
PM CET.
No match for argument: ghc:9.0/default
Error: Unable to find a match: ghc:9.0/default

Thanks,
Karel

This is now testable in Fedora with:

sudo dnf --enablerepo=updates-testing-modular install ghc:9.0/default

[ANNOUNCE] GHC 9.0.1 released

[Ben Gamari]

The GHC team is very pleased to announce the availability of GHC 9.0.1.
Source and binary distributions are available at the usual
place:

https://downloads.haskell.org/ghc/9.0.1/

In addition to numerous bug fixes, GHC 9.0.1 will bring a number of new
features:

 * A first cut of the new LinearTypes language extension [2], allowing use
   of linear function syntax and linear record fields.

 * A new bignum library, ghc-bignum, improving portability and allowing GHC
   to be more easily used with integer libraries other than GMP.

 * Improvements in code generation, resulting in considerable
   runtime performance improvements in some programs.

 * Improvements in pattern-match checking, allowing more precise
   detection of redundant cases and reduced compilation time.

 * Implementation of the "simplified subsumption" proposal [3]
   simplifying the type system and paving the way for QuickLook
   impredicativity in GHC 9.2.

 * Implementation of the QualifiedDo extension [4], allowing more
   convenient overloading of `do` syntax.

 * An experimental new IO manager implementation for Windows platforms, both
   improving performance and fixing many of the quirks with the old manager 
built
   on POSIX-emulation.

 * Improvements in compilation time.

And many more. See the release notes [5] for a full accounting of the
changes in this release.

As always, feel free to report any issues you encounter via
gitlab.haskell.org.

Cheers,

 - Ben
