+
+Release notes for version 8.10.3
+================================
+
+The significant changes to the various parts of the compiler are listed in the
+following sections.
+
+Like previous releases in the 8.10 series, the :ghc-flag:`LLVM backend <-fllvm>`
+of this release is to be used with LLVM 9.
+
+Highlights
+----------
+
+- Numerous stability improvements on Windows.
+
+- GHC now has far more robust support for architectures with weak memory
+ ordering guarantees.
+
+- GHC can split up dynamic objects to mitigate the macOS ``RPATH`` size
+ limitation when building large projects (:ghc-ticket:`14444`).
+
+- Several significant correctness bugs in the low-latency garbage collector have
+ been fixed. Users of :rts-flag:`--nonmoving-gc` are strongly encouraged to
+ upgrade promptly.
+
+
+Full details
+------------
+
+Compiler
+~~~~~~~~
+
+* A compiler crash triggered by a ``SPECIALISE`` pragma on a binding with
+ no unfolding has been fixed (:ghc-ticket:`18118`).
+
+* GHC now supports a command-line flag, :ghc-flag:`-pgmc-supports-no-pie`,
+ allowing the user to indicate that the C compiler supplied via
+ :ghc-flag:`-pgmc ⟨cmd⟩` supports ``-no-pie``.
+
+* A pair of flags, :ghc-flag:`-pgmlm ⟨cmd⟩` and :ghc-flag:`-optlm ⟨option⟩`,
+ allowing the user to override the linker used to be join GHCi object files
+ has been added.
+
+* A regression in the treatment of the :ghc-flag:`-fbyte-code` flag has been
+ fixed (:ghc-ticket:`18955`).
+
+- A bug in the determination of source spans of post-qualified imports has been
+ fixed :ghc-ticket:`19014`.
+
+
+Runtime system
+~~~~~~~~~~~~~~
+
+- GHC is now more careful to respect address space limits set via `ulimit``
+ when allocating its heap (:ghc-ticket:`18623`).
+
+- Numerous fixes on Windows. These include a bug in stack allocation
+ triggering Windows' stack verifier (:ghc-ticket:`18601`), various linker bugs
+ (:ghc-ticket:`15808`, :ghc-ticket:`18991`), and a bug where ``libc`` may be
+ called during image initialization resulting in undefined behavior
+ (:ghc-ticket:`18548`).
+
+- GHC's linker is now able to load macOS frameworks on Big Sur
+ (:ghc-ticket:`18446`).
+
+- A soundness bug affecting programs relying on heavy mutation of ``MVar``\ s
+ has been fixed (:ghc-ticket:`18919`).
+
+- The internal linker's code unloading logic has been reenabled and now tracks
+ object file dependencies, fixing a soundness bug (:ghc-ticket:`16525`).
+
+- A linker bug relying in the misalignment of loaded ``.rodata`` sections has
+ been fixed.
+
+
+Known issues
+------------
+
+- A long-standing bug (:ghc-ticket:`16893`) which can cause some applications
+ of ``unsafeCoerce`` to segmentation fault is only partially fixed in this
+ release. This release only avoids this issue in the uses of ``unsafeCoerce``
+ in ``Data.Typeable.Internal``, which was the proximate cause of
+ :ghc-ticket:`16893`.
+
+ However, it is possible that this bug could manifest in user-code using
+ ``unsafeCoerce`` to perform dynamic type checks. See the :ghc-ticket:`ticket
+ <16893>` for details.
+
+ We expect that this issue will be fixed in the next major release of GHC.
+
+- A long-standing bug (:ghc-ticket:`17760`) where some uses of the ``touch#``
+ primop can be dropped by the simplifier is present in this release. This bug
+ will be fixed in GHC 9.0.1. In the meantime, see the :ghc-ticket:`ticket
+ <17760>` for mitigations.
