Hi,
# The destination is only to haskell-cafe.

Thank you for releasing GHC 9.8.1.

I realized that "unzip" conflicts if Data.List and Data.Functor are
imported.

If this is intentional, please tell me which "unzip" we should use.

> 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].
