The GHC developers are very pleased to announce the availability of the<br>
third alpha prerelease of GHC 9.8.1. Binary distributions, source<br>
distributions, and documentation are available at<br>
<br>
<a href="https://downloads.haskell.org/ghc/9.8.1-alpha4" rel="noreferrer" target="_blank">https://downloads.haskell.org/ghc/9.8.1-alpha4</a><br>
<br>
GHC 9.8 will bring a number of new features and improvements, including:<br>
<br>
* Preliminary support the `TypeAbstractions` language extension,<br>
allowing types to be bound in type declarations [TypeAbstractions].<br>
<br>
* Support for the `ExtendedLiterals` extension, providing syntax for<br>
non-word-sized numeric literals in the surface language<br>
[extended-literals]<br>
<br>
* Improved rewrite rule matching behavior, allowing limited matching of<br>
higher-order patterns<br>
<br>
* Better support for user-defined warnings by way of the `WARNING`<br>
pragma [warnings]<br>
<br>
* The introduction of the new `GHC.TypeError.Unsatisfiable`<br>
constraint, allowing more predictable user-defined type errors<br>
[unsatisfiable]<br>
<br>
* Implementation of the export deprecation proposal, allowing module<br>
exports to be marked with `DEPRECATE` pragmas [deprecated-exports]<br>
<br>
* The addition of build semaphore support for parallel compilation;<br>
with coming support in `cabal-install` this will allow better use of<br>
parallelism in multi-package builds [jsem]<br>
<br>
* More efficient representation of info table provenance information,<br>
reducing binary sizes by over 50% in some cases when<br>
`-finfo-table-map` is in use<br>
<br>
A full accounting of changes can be found in the [release notes].<br>
This alpha includes roughly 40 new commits relative to alpha 3,<br>
including what we believe should be nearly the last changes to GHC's<br>
boot libraries.<br>
<br>
We would like to thank GitHub, IOG, the Zw3rk stake pool,<br>
Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, the Haskell<br>
Foundation, and other anonymous contributors whose on-going financial<br>
and in-kind support has facilitated GHC maintenance and release<br>
management over the years. Finally, this release would not have been<br>
possible without the hundreds of open-source contributors whose work<br>
comprise this release.<br>
<br>
As always, do give this release a try and open a [ticket] if you see<br>
anything amiss.<br>
<br>
Happy compiling,<br>
<br>
