GHC 9.10.3-rc3 is now available

wz1000 - 2025-08-08

The GHC developers are very pleased to announce the availability of the second 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.

The changes from the first release candidate are:

Reverting a change the exports of the Backtrace constructor in the base library that was backported due to confusion on CLC approvals (!14587)

Reverting a change to the configure script (!14324) that dropped probing for ld.gold

This release candidate will have a two-week testing period. If all goes well the final release will be available the week of 22 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 http://haskell.org/ghc/blog/20250808-ghc-9.10.3-rc3-released.html
