Release notes for version 8.4.3
===============================
Highlights
----------
This is a bug-fix release resolving several regressions introduced in 8.4.1.
The highlights, since the 8.4.2 release, are:
- A bug (:ghc-ticket:`15068`) causing GHC to produce assembler that would be rejected by
some versions of GNU Binutils, has been fixed.
- ``GHC.Compact.compact`` now properly handles ``SmallArray``\ s (:ghc-ticket:`13857`)
- A bug (:ghc-ticket:`15038`) resulting in memory corruption and crashes in some uses of
unboxed sums has been fixed.
- GHC now logs a message when an :ref:`environment file <package-environments>`
is loaded (:ghc-ticket:`15145`).

In addition to the highlights listed above, this release resolves a number of
other issues, described below.
