It seems that no new release is needed for GHC 9.6 (builds locally), but our testsuites are blocked on the ecosystem.

BNFC doctests:

• blocked on Build failure on GHC 9.6 sol/doctest#394

bnfc-system-tests:

• blocked on Build failure with mtl-2.3 skogsbaer/HTF#118
• blocked on Support unix-2.8.0.0 jacobstanley/unix-compat#61

TODOs:

• add bnfc-system-tests to CI for 9.6
• reenable doctests in CI, but only for non-head job
• fix caching in stack workflow (busts 10G limit)
• update stack-9.2.*.yaml files
