Futhark is a programming language that supports parallelism and belongs to the ML family.

Added:

• The internal representation of parallel constructs has been revised and optimized. With rare exceptions, this can significantly impact performance.
• There is now support for structurally typed sum types and pattern matching. However, there are still some issues with sum types that contain arrays themselves.
• Compilation time for some large programs has been significantly reduced.
• Manually specified type parameters no longer need to be exhaustive.
• The display of the rotate parameter has been simplified.

Removed

• The prefix operator ~ is no longer used, and ! can now be applied for performing bitwise negation of integers.

Changed:

• The --futhark option for futhark bench and futhark test now defaults to the binary used for the commands themselves.
• The deprecated futhark -t option (which performed the same function as futhark check) has been removed.
• stream_map has become map_stream, and stream_red – reduce_stream.

Fixed:

• futhark test now 'understands' --no-tuning as originally intended.
• The futhark bench and futhark test commands now properly interpret --exclude.
• The backend in Python and C# can now correctly read binary data.
