[ANNOUNCE] GHC 8.10.4 released

The GHC team is very pleased to announce the availability of GHC 8.10.4. Source and binary distributions are available at the usual place: https://downloads.haskell.org/ghc/8.10.4/ This is a small bug-fix release, fixing two bugs present in 8.10.3: * Fix a linker hang triggered by dynamic code loading on Windows (#19155) * Fix a crash caused by inappropriate garbage of heap-allocated data reachable from foreign exports (#19149) As always, feel free to report any issues you encounter via [gitlab.haskell.org](https://gitlab.haskell.org/ghc/ghc/-/issues/new). Cheers, - Ben
