+* GHC now supports visible type applications in patterns when :extension:`TypeApplications` is enabled . This allows
+ you to use the ``@variable`` syntax to bind types in patterns. For instance, instead of ::
+
+ foo (Just (x :: ty)) = …
+
+ You can now use
+
+ foo (Just @ty x) = …

* Kind inference for data/newtype instance declarations is slightly more restrictive than before.
In particular, GHC now requires that the kind of a data family instance be fully determined
by the header of the instance, without looking at the definition of the constructor.

+9, 10, 11, or 12.
+
+Compiler
+--------
+
+- Fix a regression in the simplifier due to a bad backport in GHC 9.2.5 that
+ could seriously impact runtime performance when compiling with optimisations
+ due to duplication of expensive work (:ghc-ticket:`22425`).
+
+- Fix a compiler panic in the simplifier due to a bad backport in GHC 9.2.5
+ (:ghc-ticket:`22491`).
+
+- Fix a compiler panic in the simplifier that manifests when compiling with
+ optimisations (:ghc-ticket:`19824`,:ghc-ticket:`22482`).
+
+- Fix a compiler panic in the demand analyser due to a bug involving shadowing
+ (:ghc-ticket:`22718`).
+
+- Fix a compiler panic during the "Float In" optimsation pass due to improper
+ handling of shadowing (:ghc-ticket:`22662`).
+
+- Fix a compiler panic in the demand analyser (:ghc-ticket:`22039`).
+
+- Fix a shadowing related bug in the occurence analysis phase of the simplifier
+ (:ghc-ticket:`22623`).
+
+- Fix a compiler bug where programs using Template Haskell involving Constant
+ Applicative forms could be garbage collected too early (:ghc-ticket:`22417`).
+
+- Fix a regression in the typechecker where certain typeclass instances
+ involving type and data familes would fail to resolve (:ghc-ticket:`22647`).
+
+- Fix the linker warning about chained fixups on Darwin platforms for programs
+ compiled with GHC (:ghc-ticket:`22429`).
+
+- Fix a bug with the graph-colouring register allocater leading to compiler
+ panics when compiling with ``-fregs-graph`` (:ghc-ticket:`22798`).
+
+- Fix a parser bug where certain keywords which could be used as variables
+ were not allowed to be used with :extension:`OverloadedRecordDot`
+ (:ghc-ticket:`20723`).
+
+- Fix the location of some ``Typeable`` definitions from ``GHC.Types`` which
+ resulted in poor error messages (:ghc-ticket:`22510`).
+
+- Improve error messages involving non-exhaustive patterns when using
+ :extension:`ApplicativeDo` (:ghc-ticket:`22483`).
+
+- Fix a driver bug where certain non-fatal Safe Haskell related warnings were
+ being marked as fatal (:ghc-ticket:`22728`).
+
+Runtime system
+--------------
+
+- Fix a GC bug where a race condition in the parallel GC could cause it to
+ garbage collect live sparks (:ghc-ticket:`22528`).
+
+- Truncate eventlog events with a large payload (:ghc-ticket:`20221`).
+
+Build system and packaging
+--------------------------
+
+- Bump ``gmp-tarballs`` to a version which doesn't use the reserved ``x18``
+ register on AArch64/Darwin systems, and also has fixes for CVE-2021-43618
+ (:ghc-ticket:`22497`, :ghc-ticket:`22789`).
+
+- Include haddock documentation in interface files for hadrian generated
+ bindists, including darwin platforms (:ghc-ticket:`22734`).
+
+Core libraries
+--------------
+
+- Bump ``bytestring`` to 0.11.4.0.
