+Version 9.8.2
+==============
+
+The significant changes to the various parts of the compiler are listed below.
+See the `migration guide
+<https://gitlab.haskell.org/ghc/ghc/-/wikis/migration/9.8>`_ on the GHC Wiki
+for specific guidance on migrating programs to this release.
+
+The :ghc-flag:`LLVM backend <-fllvm>` of this release is to be used with LLVM
+11, 12, 13, 14 or 15.
+
+Significant Changes
+~~~~~~~~~~~~~~~~~~~~
+
+Issues fixed in this release include:
+
+Compiler
+--------
+
+- Fix a recompilation checking bug impacting the relinking step, where we failed to
+  relink if transitive dependencies were changed (:ghc-ticket:`23724`).
+- Fix a renamer bug where certain styles of import lists for associated type
+  families would not be processed correctly (:ghc-ticket:`24084`).
+- Fix a typechecker bug that could lead to non-termination in certain situations
+  (:ghc-ticket:`24134`).
+- Support code points greater than 2^16 in ``toJSString`` when using the JS
+  backend (:ghc-ticket:`23628`).
+- Fix a code generation bug on the JS backend involving tuple constructors
+  (:ghc-ticket:`23659`).
+- Fix a code generator panic when compiling code using FMA primops
+  (:ghc-ticket:`24160`).
+- Fix a bug causing suboptimal error messages for certain invalid cyclic
+  module graphs with hs-boot files (:ghc-ticket:`24196`, :ghc-ticket:`24275`).
+- Fix an incorrect assertion in the simplifier (:ghc-ticket:`23862`).
+- Fix a bug causing compiler panics with certain package databases involving
+  unusable units and module reexports (:ghc-ticket:`21097`, :ghc-ticket:`16996`,
+  :ghc-ticket:`11050`).
+- Fix some memory leaks in GHCi that manifest on reloads (:ghc-ticket:`24107`,
+  :ghc-ticket:`24118`).
+- Fix a GHCi bug where a failure in the ``:add`` command would cause the
+  process to exit (:ghc-ticket:`24115`).
+- Align objects in the data section properly when using the LLVM backend
+  (:ghc-ticket:`24163`).
+- Fix a simplifier panic when simplifying certain unfoldings
+  (:ghc-ticket:`24242`).
+- Fix a typechecker bug where ``TYPE`` and ``CONSTRAINT`` were treated as apart
+  (:ghc-ticket:`24279`).
+- Allow template haskell code to look up record fields (:ghc-ticket:`24293`).
+- Add ``-finfo-table-map-with-fallback`` and ``-finfo-table-map-with-stack`` flags
+  for info table profiling (:ghc-ticket:`23702`).
+- Improve compile time and code generation performance when ``-finfo-table-map``
+  is enabled (:ghc-ticket:`23103`).
+- Fix a bug in the check for unused type variables in type class instances
+  (:ghc-ticket:`23768`).
+- Fix a panic when typechecking GADT data family instances with unused variables
+  (:ghc-ticket:`23784`).
+- Improve error message for unused variables in RHS of data family instance
+  (:ghc-ticket:`23778`).
+- Fix a compiler panic due to mismatches between ``.hs`` and ``.hs-boot`` files
+  (:ghc-ticket:`16127`).
+- Improve error message for unused variables type family instances
+  (:ghc-ticket:`23734`).
+- Fix a type checker crash on certain programs involving implicitly scoped type
+  variables (:ghc-ticket:`24083`).
+- Fix a bug where certain warning flags were not recognised (:ghc-ticket:`24071`).
+- Fix a bug involving the miscompilation of certain loops (:ghc-ticket:`24295`).
+- Produce FMA instructions even if `-mfma` is not set on AArch64
+  (:ghc-ticket:`24311`).
+- Fix a bug leading to some template haskell splices failing on being reloaded
+  into GHCi due to not clearing the interactive context properly
+  (:ghc-ticket:`23405`).
+- Fix a bug where we could silently truncate 64 bit values to 32 bit on
+  32 bit architectures.
+- Don't produce invalid opcode for FMA instruction on LLVM (:ghc-ticket:`24223`).
+- Fix a warning about non-existent ``+fma`` flag on LLVM (:ghc-ticket:`24379`).

+  primitives (:ghc-ticket:`24222`).
+- Fix a bug preventing haddock from computing the correct links
+  (:ghc-ticket:`24294`).
+
+Runtime system
+--------------
+
+- Ensure we respect maximum event length and don't overflow into program
+  memory (:ghc-ticket:`24197`, :ghc-ticket:`24287`).
+- Ensure concurrent thunk update is sound (:ghc-ticket:`23185`).
+
+Build system and packaging
+--------------------------
+
+- Ensure we use the right ``otool`` and ``install_name_tool`` on Darwin
+  (:ghc-ticket:`24211`).
+- Ensure we use the correct bindist name for the test artifact when generating
+  release ghcup metadata (:ghc-ticket:`24268`).
+- Ensure we handle CXX and CC flags involving standard flags correctly with
+  new autotools versions (:ghc-ticket:`24324`). 
+- Ensure we correctly set ``--target`` when configuring the linker
+  (:ghc-ticket:`24414`).
+- Suppress duplicate library warnings on new macOS linker (:ghc-ticket:`24167`,
+  :ghc-ticket:`24168`).
+- Fix a bug where ``-DNOSMP`` wasn't being passed to the C compiler even if the
