The GHC developers are happy to announce the availability of GHC 9.4.7.  
Binary distributions, source distributions, and documentation are  
available at

```

The GHC developers are happy to announce the availability of GHC 9.4.7. Binary  
distributions, source distributions, and documentation are available at  
[downloads.haskell.org](https://downloads.haskell.org/ghc/9.4.7).

This release is primarily a bugfix release addressing some issues  
found in 9.4.6. These include:

- A bump to bytestring-0.11.5.2 allowing GHC to be bootstrapped on  
systems where the bootstrap compiler is built with the `pthread_condattr_setclock`  
symbol available (#23789).
- A number of bug fixes for scoping bugs in the specialiser, preventing  
simplifier panics (#21391, #21689, #21828, #23762).
- Distributing dynamically linked alpine bindists (#23349, #23828).
- A bug fix for the release notes syntax, allowing them to built on  
systems with older python and sphinx versions (#23807, #23818).
- … and a few more. See the [release notes](https://downloads.haskell.org/~ghc/9.4.7/docs/users_guide/9.4.7-notes.html) for a full accounting.

We would like to thank Microsoft Azure, GitHub, IOG, the Zw3rk stake pool,  
Well-Typed, Tweag I/O, Serokell, Equinix, SimSpace, Haskell Foundation, and  
other anonymous contributors whose on-going financial and in-kind support has  
facilitated GHC maintenance and release management over the years. Finally,  
this release would not have been possible without the hundreds of open-source  
contributors whose work comprise this release.

As always, do give this release a try and open a [ticket](https://gitlab.haskell.org/ghc/ghc/-/issues/new) if you see  
anything amiss.

Happy compiling,

- Zubin

Many thanks to the GHC team. Two minor points on the web site:

GHC 9.4.7 comes with (non-static) bindists for Alpine Linux ([GHC Guide 2.1.1.2](https://downloads.haskell.org/~ghc/9.4.7/docs/users_guide/9.4.7-notes.html#build-system-and-packaging)). However, that is not acknowledged with the options presented at [GHC 9.4.7 download — The Glasgow Haskell Compiler](https://www.haskell.org/ghc/download_ghc_9_4_7.html). Could it be?

The link for 9.4.7 at [Download — The Glasgow Haskell Compiler](https://www.haskell.org/ghc/download.html) points to GHC 9.4.6’s page.

I have updated Stack’s default `setup-info` dictionary for these binary distributions, and added GHC 9.4.7’s global hints to `global-hints.yaml`.

Thanks for pointing these out. @mpilgrem.

While I was there I took the liberty of fixing a few other mistakes on the downloads page: [!158: Some fixes to the downloads pages · Merge requests · Glasgow Haskell Compiler / homepage · GitLab](https://gitlab.haskell.org/ghc/homepage/-/merge_requests/158)
