+Release notes for version 8.4.4
+===============================
+
+Highlights
+----------
+
+This is a bug-fix release resolving several regressions introduced in 8.4.1.
+
+The highlights, since the 8.4.3 release, are:
+
+- A bug which could result in memory unsafety with certain uses of ``touch#``
+  has been resolved. (:ghc-ticket:`14346`)
+
+- A compiler panic triggered by some GADT record updates has been fixed
+  (:ghc-ticket:`15499`)
+
+- The ``text`` library has been updated, fixing several serious bugs in the
+  version shipped with GHC 8.4.3 (see `#227
+  <https://github.com/haskell/text/issues/227>`_,
+  `#221 <https://github.com/haskell/text/issues/221>`_, and `#197
+  <https://github.com/haskell/text/issues/197>`_.
+
+- A serious code generation bug in the LLVM code generation, potentially resulting
+  in incorrect evaluation of floating point expressions, has been fixed
+  (:ghc-ticket:`14251`)
+
+
+Full details

+In addition to the highlights listed above, this release resolves a number of
