9.4.1. Binary distributions, source distributions, and documentation are<br>
available at <a href="http://downloads.haskell.org" rel="noreferrer noreferrer" target="_blank">downloads.haskell.org</a>:<br>

<br>
This release includes:<br>
<br>
- A new profiling mode, `-fprof-late`, which adds automatic cost-center<br>
annotations to all top-level functions *after* Core optimisation has<br>
run. This provides informative profiles while interfering<br>
significantly less with GHC's aggressive optimisations, making it<br>
easier to understand the performance of programs which depend upon<br>
simplification..<br>
<br>
- A variety of plugin improvements including the introduction of a new<br>
plugin type, *defaulting plugins*, and the ability for typechecking<br>
plugins to rewrite type-families.<br>
<br>
- An improved constructed product result analysis, allowing unboxing of<br>
nested structures, and a new boxity analysis, leading to less reboxing.<br>
<br>
- Introduction of a tag-check elision optimisation, bringing<br>
significant performance improvements in strict programs.<br>
<br>
- Generalisation of a variety of primitive types to be levity<br>
polymorphic. Consequently, the `ArrayArray#` type can at long last be<br>
retired, replaced by standard `Array#`.<br>
<br>
- Introduction of the `\cases` syntax from [GHC proposal 0302].<br>
<br>
- A complete overhaul of GHC's Windows support. This includes a<br>
migration to a fully Clang-based C toolchain, a deep refactoring of<br>
the linker, and many fixes in WinIO.<br>
<br>
- Support for multiple home packages, significantly improving support<br>
in IDEs and other tools for multi-package projects.<br>
<br>
- A refactoring of GHC's error message infrastructure, allowing GHC to<br>
provide diagnostic information to downstream consumers as structured<br>
data, greatly easing IDE support.<br>
<br>
- Significant compile-time improvements to runtime and memory consumption.<br>
<br>
- On overhaul of our packaging infrastructure, allowing full<br>
traceability of release artifacts and more reliable binary<br>
distributions.<br>
<br>
- Reintroduction of deep subsumption (which was previously dropped with the<br>
*simplified subsumption* change) as a language extension.<br>
<br>
- ... and much more. See the [release notes] for a full accounting.<br>
<br>
Note that, as 9.4.1 is the first release for which the released artifacts will<br>
all be generated by our Hadrian build system, it is possible that there will be<br>
packaging issues. If you enounter trouble while using a binary distribution,<br>
please open a [ticket]. Likewise, if you are a downstream packager, do consider<br>
migrating to [Hadrian] to run your build; the Hadrian build system can be built<br>
using `cabal-install`, `stack`, or the in-tree [bootstrap script]. See the accompanying<br>
[blog post] for details on migrating packaging to Hadrian.<br>
<br>
We would like to thank Microsoft Azure, GitHub, IOG, the Zw3rk stake pool,<br>
Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, Haskell Foundation, and<br>
other anonymous contributors whose on-going financial and in-kind support has<br>
facilitated GHC maintenance and release management over the years. Finally,<br>
this release would not have been possible without the hundreds of open-source<br>
contributors whose work comprise this release.<br>
<br>
As always, do give this release a try and open a [ticket] if you see<br>
anything amiss.<br>
<br>
Happy testing,<br>
