haskell-src-exts v1.12.0 Release Notes

    • ➕ Add extensions DoAndIfThenElse and NPlusKPatterns to Language.Haskell.Exts.Extensions.

    • 👍 DoAndIfThenElse is now supported, at long last, making HSE compatible with Haskell2010

    • Introduce haskell98 and haskell2010 extension groups, exported from Language.Haskell.Exts.Extensions.

    • 0️⃣ Backwards-incompatible change: default parse mode is now to use haskell2010, which means the following features are recognized by default: DoAndIfThenElse, PatternGuards, ForeignFunctionInterface, EmptyDataDecls. NPlusKPatterns is no longer recognized by default.
