Added

• The GPU loop tiler can now handle loops where only a subset of the
  input arrays are tiled. Matrix-vector multiplication is one
  important program where this helps (#1145).

• The number of threads used by the multicore backend is now
  configurable (--num-threads and
  futhark_context_config_set_num_threads()). (#1162)

Fixed

• PyOpenCL backend would mistakenly still streat entry point
  argument sizes as 32 bit.

• Warnings are now reported even for programs with type errors.

• Multicore backend now works properly for very large iteration
  spaces.

• A few internal generated functions (init_constants(),
  free_constants()) were mistakenly declared non-static.

• Process exit code is now nonzero when compiler bugs and
  limitations are encountered.

• Multicore backend crashed on reduce_by_index with nonempty target
  and empty input.

• Fixed a flattening issue for certain complex map nestings
  (#1168).

• Made API function futhark_context_clear_caches() thread safe
  (#1169).

• API functions for freeing opaque objects are now thread-safe
  (#1169).

• Tools such as futhark dataset no longer crash with an internal
  error if writing to a broken pipe (but they will return a nonzero
  exit code).

• Defunctionalisation had a name shadowing issue that would crop up
  for programs making very advanced use of functional
  representations (#1174).

• Type checker erroneously permitted pattern-matching on string
  literals (this would fail later in the compiler).

• New coverage checker for pattern matching, which is more correct.
  However, it may not provide quite as nice counter-examples
  (#1134).

• Fix rare internalisation error (#1177).
