Added

• New fusion engine by Amar Topalovic and Walter Restelli-Nielsen.
  Fuses more, which is good for some programs and bad for others.
  Most programs see no change. This is mainly a robust foundation for
  further improvements.

• New experimental backend: ispc. By Louis Marott Normann,
  Kristoffer August Kortbæk, William Pema Norbu Holmes Malling, and
  Oliver Bak Kjersgaard Petersen.

• New prelude functions: hist, spread. These function as
  non-consuming variants of reduce_by_index and scatter.

• Using == to compare arrays is now deprecated.

• New command: futhark tokens. You probably don't care about this one.

• In the C API, opaque types that correspond to tuples or records can
  now have their elements inspected and be created from elements
  (#1568).

• New server protocol commands: types, fields, entry_points.

• Tuples and records can now be passed from FutharkScript to Futhark
  entry points (#1684).

Fixed

• Sometimes missing cases in match expressions were not detected.

• A defective simplification rule could in very rare cases lead to
  infinite recursion in the compiler (#1685).

• Some broken links in futhark doc output (#1686).

• Incorrect checking of whether a function parameter is consumable
  based on its type (#1687).

• Missing aliases for functions that return multiple aliased values
  (#1690).

• new/values functions for GPU backends are now properly
  asynchronous (#1664). This may uncover bugs in application code.
