Added

• futhark literate now supports a $loadimg builtin function for
  passing images to Futhark programs.

• The futhark literate directive for generating videos is now
  :video.

• Support for 64-bit atomics on CUDA and OpenCL for higher
  performance with reduce_by_index in particular.
  Double-precision float atomics are used on CUDA.

• New functions: f32.recip and f64.recip for multiplicative inverses.

• Executables produced with the c and multicore backends now
  also accept --tuning and --size options (although there are
  not yet any tunable sizes).

• New functions: scatter_2d and scatter_3d for scattering to
  multi-dimensional arrays (#1258).

Removed

• The math modules no longer define the name negate (use neg
  instead).

Fixed

• Exotic core language alias tracking bug (#1239).

• Issue with entry points returning constant arrays (#1240).

• Overzealous CSE collided with uniqueness types (#1241).

• Defunctionalisation issue (#1242).

• Tiling inside multiply nested loops (#1243).

• Substitution bug in interpreter (#1250).

• f32.sgn/f64.sgn now correct for NaN arguments.

• CPU backends (c/multicore) are now more careful about staying
  in single precision for f32 functions (#1253).

• futhark test and futhark bench now detect program
  initialisation errors in a saner way (#1246).

• Partial application of operators with parameters used in a
  size-dependent way now works (#1256).

• An issue regarding abstract size-lifted sum types (#1260).
