> GHC 9.8 brings a number of new features and improvements, including:
>
> * Preliminary support the `TypeAbstractions` language extension,
> allowing types to be bound in type declarations [TypeAbstractions].
>
> * 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][].
> Plans for GHC's future releases can be found on the [GHC Wiki][status].

> 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.
