GHC 9.6.3 is now available

Bryan Richter - 2023-09-25

The GHC developers are happy to announce the availability of GHC 9.6.3. Binary distributions, source distributions, and documentation are available on the release page.

This release is primarily a bugfix release addressing a few issues found in the 9.6 series. These include:

Disable Polymorphic Specialisation (a performance optimisation) by default. It was discovered that Polymorphic Specialisation as currently implemented in GHC can lead to hard to diagnose bugs resulting in incorrect runtime results. Users wishing to use this optimisation despite the caveats will now have to explicitly enable the new -fpolymorphic-specialisation flag. For more details see #23469 as well as #23109, http://haskell.org/ghc/blog/20230925-ghc-9.6.3-released.html
