Re: [Haskell-cafe] [ANNOUNCE] GHC 9.8.1-alpha2 is now available

😱 Thanks Sam and Noon! I'm obviously great at copy-pasting. On Tue, 22 Aug 2023 at 14:36, Noon van der Silk wrote:

Hey Arnaud,

I assume you mean "TypeApplications" instead of "TypeApplications", right?

:D

The GHC developers are very pleased to announce the availability of the second alpha prerelease of GHC 9.8.1. Binary distributions, source distributions, and documentation are available at

https://downloads.haskell.org/ghc/9.8.1-alpha2

GHC 9.8 will bring a number of new features and improvements, including:

* Preliminary support the `TypeApplications` language extension [type-binders], allowing types to be bound in type declarations.

* Support for the `ExtendedLiterals` extension, providing syntax for non-word-sized numeric literals in the surface language [extended-literals]

* Improved rewrite rule matching behavior, allowing limited matching of higher-order patterns

* Better support for user-defined warnings by way of the `WARNING` pragma [warnings]

* The introduction of the new `GHC.TypeError.Unsatisfiable` constraint, allowing more predictable user-defined type errors [unsatisfiable]

* Implementation of the export deprecation proposal, allowing module exports to be marked with `DEPRECATE` pragmas [deprecated-exports]

* The addition of build semaphore support for parallel compilation; with coming support in `cabal-install` this will allow better use of parallelism in multi-package builds [jsem]

* More efficient representation of info table provenance information, reducing binary sizes by over 50% in some cases when `-finfo-table-map` is in use

A full accounting of changes can be found in the [release notes]. This alpha includes around two dozen bug-fixes relative to alpha 1.

We would like to thank GitHub, IOG, the Zw3rk stake pool, Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, the Haskell Foundation, and other anonymous contributors whose on-going financial and in-kind support has facilitated GHC maintenance and release management over the years. Finally, 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 compiling,

~ Ben
