Release notes for version 8.4.2
===============================
TODO
Highlights
----------
This is a bug-fix release resolving several regressions introduced in 8.4.1.
The highlights, since the 8.4.1 release, are:
- TODO
- Fixed a regression causing uses of ``Control.Exception.evaluate`` to be
incorrectly optimised, resulting in space leaks (:ghc-ticket:`13930`)
- Fix a regression causing the interpreter to segmentation fault when built with
profiling (:ghc-ticket:`14705`)

Compiler
~~~~~~~~
In addition to the regressions listed above, this release fixes a bug affecting
GHC's debug output support (:ghc-flag:`-g`) which resulted in invalid code to be
generated for string literals (:ghc-ticket:`13868`)
- :ghc-ticket:`14918`, where ``Read`` instances for types with field names
containing ``#`` would fail to parse, has been fixed.
Runtime system
~~~~~~~~~~~~~~
- A bug causing panics while running programs with :rts-flag:`-hr` was fixed
(:ghc-ticket:`14947`)
Template Haskell
~~~~~~~~~~~~~~~~
No changes.
``ghc`` library
~~~~~~~~~~~~~~~
No changes.
``base`` library
~~~~~~~~~~~~~~~~
- Version bumped to 4.11.1.0 to account for the addition of
``GHC.IO.FixIOException``
- Add the ``readFieldHash`` function to ``GHC.Read`` which behaves like
``readField``, but for a field that ends with a ``#`` symbol.
``integer-gmp`` library
~~~~~~~~~~~~~~~~~~~~~~~
- Version bumped to 1.0.2.0 to account for the addition of ``powModSecInteger``.
- Define ``powModSecInteger``, a "secure" version of ``powModInteger`` using
the ``mpz_powm_sec`` function.
Build system
~~~~~~~~~~~~
- ``configure`` now takes a ``--disable-dtrace`` flag, allowing workaround of
:ghc-ticket:`15040`.
