   * Introduce `Data.Bounded` module exporting the `Bounded` typeclass ([CLC proposal #208](https://github.com/haskell/core-libraries-committee/issues/208))

   * Shipped with GHC 9.10.1
+  * Introduce `Data.Enum` module exporting both `Enum` and `Bounded`. Note that the export of `Bounded` will be deprecated in a future release ([CLC proposal #208](https://github.com/haskell/core-libraries-committee/issues/208))
   * Deprecate `GHC.Pack` ([#21461](https://gitlab.haskell.org/ghc/ghc/-/issues/21461))
   * Export `foldl'` from `Prelude` ([CLC proposal #167](https://github.com/haskell/core-libraries-committee/issues/167))
   * The top-level handler for uncaught exceptions now displays the output of `displayException` rather than `show`  ([CLC proposal #198](https://github.com/haskell/core-libraries-committee/issues/198))
