+
+Version 9.6.7
+==============
+
+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
+--------
+
+- Fixed a bug that caused GHC to panic when using the AArch64 ncg and :ghc-flag:`-fregs-graph` on certain programs (:ghc-ticket:`24941`).
+- Fix invalid optimisation of Cmm programs on 32-bit platforms when targetting 64-bit targets (:ghc-ticket:`24893` and :ghc-ticket:`24700`).
+- Improve float-out surrounding applications of ``runRW#`` (:ghc-ticket:`25055`).
+- Fix :ghc-flag:`-fregs-graph` crash when targetting AArch64 (:ghc-ticket:`24941`).
+- Fix code generation of foreign exports with more than 6 arguments when some are subword-width (:ghc-ticket:`24314`).
+- Fix recompilation avoidance behavior of :ghc-flag:`-fwrite-if-simplified-core` (:ghc-ticket:`24656`).
+- Fix linking error when :extension:`TypeData` and :extension:`StrictData` are in use (:ghc-ticket:`24620`).
+- :ghc-flag:`-Wmissing-home-modules` now behaves correctly when multiple units have expose the same module name (:ghc-ticket:`25122`).
+- Adjust the demand signature of the ``prompt#`` to avoid invalid optimisation of non-terminating programs (:ghc-ticket:`25439`).
+- GHC's internal ``Unique`` type has been widened to 64-bits on 32-bit architectures, avoiding potential miscompilations on large projects (:ghc-ticket:`22010`).
+- Fix LLVM version detection on newer LLVM versions (:ghc-ticket:`25606`).
+- Determine ``max_n_capabilities`` at RTS startup, removing the previous static cap at 256 (:ghc-ticket:`25560`).
+- Fix out-of-bounds memory mapping logic, resolving an infinite loop on FreeBSD (:ghc-ticket:`25492`).
+- Find C++ probing when GCC version is the latest but G++ is old (:ghc-ticket:`23118`).
+- Consider Wanteds with rewriters as insoluble, fixing a situation where the program fails to typecheck but no errors are reported (:ghc-ticket:`25325`).
+- Fix x86 NCG foreign argument promotion. The x86 NCG now correctly promotes 8 bit and 16 bits arguments by sign extension (:ghc-ticket:`25018`).
+- Fix GHC flag ``-working-dir`` for foreign files (:ghc-ticket:`25150`).
+- Added new flags :ghc-flag:`-fspec-eval` and :ghc-flag:`-fspec-eval-dictfun` to allow switching off speculative evaluation (:ghc-ticket:`25284`).
+- Fix a runtime crash when using the compacting GC, caused by black holes in large objects (:ghc-ticket:`24791`).
+
+Hadrian and builds
+------------------
+
+- Bump the minimum version of the `directory` dependency for Hadrian to 1.3.9.0 to avoid a race condition on Windows (:ghc-ticket:`#24382`). Also updated the bootstrap build plans for hadrian.
+- Hadrian: Set `-this-package-name`. This fixes package imports for `ghci-multi` and was required to update the `unix` package.
+- Add Ubuntu 22.04 builds for nightlies and release (:ghc-ticket:`25317`).
+
+JavaScript backend
+------------------
+
+- Fix compiler crash involving rubbish literals (:ghc-ticket:`25177`, :ghc-ticket:`24664`).
+
+``base``
+--------
+
+- Bump version to 4.18.2.2
+- Fix spurious closing of file descriptors after ``fork`` on platforms using
+ the KQueue event manager backend (:ghc-ticket:`24672`), visible on FreeBSD.
+
+Other Core Libraries
+--------------------
+
+- The ``filepath`` library has been upgraded to 1.4.301.0, fixing a potentially
+ exploitable behavior with ``splitFileName`` on Windows (:ghc-ticket:`24597`).
+- ``unix-2.8.6.0`` is included, fixing an `issue
+ <https://github.com/haskell/unix/pull/252>`_ affecting ``musl`` targets.
+- ``bytestring`` has been upgraded to 0.11.5.4, fixing a race condition in
+ ``toLazyByteString`` that could generate wrong results if two threads
+ concurrently evaluated the result.
+- ``array`` has been upgraded to 0.5.8.0.
+- ``ghc-bignum``: the bundled gmp library has been upgraded to 6.3.0.
