Subject: [ANNOUNCE] GHC 9.0.1 released
Message-ID: <87wnvnsoc5.fsf@smart-cactus.org>

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

Message-ID: <874kip41kq.fsf@smart-cactus.org>

The GHC team is very pleased to announce the availability of GHC 8.10.4.
Source and binary distributions are available at the usual
place:

    https://downloads.haskell.org/ghc/8.10.4/

This is a small bug-fix release, fixing two bugs present in 8.10.3:

* Fix a linker hang triggered by dynamic code loading on Windows
  (#19155)

* Fix a crash caused by inappropriate garbage of heap-allocated data reachable
  from foreign exports (#19149)

As always, feel free to report any issues you encounter via

This is now testable in Fedora with:

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

Thanks, Jens

Thank you!

This is now already built for Fedora and can be tested/installed with:

dnf --enablerepo=updates-testing-modular module install ghc:8.10/default

It should go stable after one week (after which you don't need the
--enablerepo option).

Subject: [ANN] cabal-install-3.4.0.0
Message-ID: <klin3ovy.8bc5ea4f-d60e-4041-92f3-387fc8c658ca@we.are.superhuman.com>

The Cabal team is excited to announce the release of cabal-install 3.4. This is the third release of the 3.0 release series, bringing a support for the `Cabal-Version: 3.4` `.cabal` file format. This introduces a number of user-facing features including:

- Support for GHC 9.0

- Package sublibrary dependency syntax

- Allowing omission of the `default-language` declaration

- A mixins field allowing the user to specify a sublibrary

- [Many other features]( https://cabal.readthedocs.io/en/latest/file-format-changelog.html#cabal-version-3-4 )

In addition, the `cabal-install` frontend itself has gained a number of new features including:

- New `active-repositories` `cabal.project` fields allowing users to specify an order and various ways of combining package repositories

- Improvements to `cabal init`

- A rework of the `cabal v2-sdist` command. `cabal v1-sdist` is removed as of this version

- `source-repository-package` directories are no longer local

- A new `list-bin` command

- `cabal sandbox` is now removed in favor of default nix-style builds

- `cabal list` now accepts regular expressions

- More rich `index-state` syntax. `v2-freeze` saves `index-state`

I'd also like to thank the many contributors who offered patches, tickets, and other help in the preparation of this release. We appreciate all of your help!

For a full set of release notes, see https://github.com/haskell/cabal/blob/master/release-notes/cabal-install-3.4.0.0.md. If you have issues, we'd love to hear about there here: https://github.com/haskell/cabal/issues.

Happy hacking!

Emily
