+* 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.

+
+Version 9.2.6
+==============
+
+The significant changes to the various parts of the compiler are listed in the
+following sections.
+
+The :ghc-flag:`LLVM backend <-fllvm>` of this release is to be used with LLVM
+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.
+
+Included libraries
