> 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.
