GHC 9.10.3-rc1 is now available

The GHC developers are very pleased to announce the availability
of the release candidate for GHC 9.10.3. Binary distributions, source
distributions, and documentation are available at downloads.haskell.org and
via GHCup.

GHC 9.10.3 is a bug-fix release fixing over 50 issues of a variety of
severities and scopes. A full accounting of these fixes can be found in the
release notes. As always, GHC’s release status, including planned future
releases, can be found on the GHC Wiki status.

This release candidate will have a two-week testing period. If all goes well
the final release will be available the week of 11 August 2025.

We would like to thank Well-Typed, Tweag I/O, Juspay, QBayLogic, Channable,
Serokell, SimSpace, the 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 if you see
anything amiss.

Very happy to see !14084: Don't cache solved [W] HasCallStack constraints · Merge requests · Glasgow Haskell Compiler / GHC · GitLab included!! Thanks a lot to all involved and especially to you @wz1000 for doing this release.

Atm, it is not available as the metadata has not been merged into the prerelease channel yet:

Ok, installed it with ghcup now!
