Added

• A new memory reuse optimisation has been added. This results in
  slightly lower footprint for many programs.

• The cuda backend now uses a fast single-pass implementation for
  segmented scans, due to Morten Tychsen Clausen (#1375).

• futhark bench now prints interim results while it is running.

Fixed

• futhark test now provides better error message when asked to
  test an undefined entry point (#1367).

• futhark pkg now detects some nonsensical package paths (#1364).

• FutharkScript now parses f x y as applying f to x and y,
  rather than as f (x y).

• Some internal array utility functions would not be generated if
  entry points exposed both unit arrays and boolean arrays (#1374).

• Nested reductions used (much) more memory for intermediate results
  than strictly needed.

• Size propagation bug in defunctionalisation (#1384).

• In the C FFI, array types used only internally to implement opaque
  types are no longer exposed (#1387).

• futhark bench now copes with test programs that consume their
  input (#1386). This required an extension of the server protocol
  as well.
