+
+Release notes for version 8.8.4
+===============================
+
+GHC 8.8.4 is a minor release intended to fix regressions and minor bugs in the
+8.8.1, 8.8.2 and 8.8.3 releases.
+
+Highlights
+----------
+
+- Fix a bug in process creation on Windows (:ghc-ticket:`17926`).
+
+- Workaround a Linux kernel bug in the implementation of ``timerfd``\s (:ghc-ticket:`18033`).
+
+
+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.
+
+- The simplifier can optimise away some applications of the ``touch#`` primop
+ when it can prove that the ``touch#`` is unreachable due to divergence or
+ synchronous exception, resulting in memory unsoundness. Users requiring
+ ``touch#`` behavior are advised to only use ``touch#`` to implement
+ continuation-passing-style primitives (e.g. in the style of
+ ``withForeignPtr``) bearing ``NOINLINE`` pragmas (to avoid inappropriate
+ simplification). See :ghc-ticket:`17760` for details.
+
+Included libraries
+------------------
+
+The package database provided with this distribution also contains a number of
+packages other than GHC itself. See the changelogs provided with these packages
+for further change information.
