Added

• Futhark now implements the cachedir specification, such that e.g. the data
  directories created by futhark test and futhark bench contain a
  CACHEDIR.TAG file.

• C types corresponding to records now have nicer names.

• futhark script now has a $restore procedure, and the $store
  procedure has been augmented with support for opaque types.

• The expression guarded by an assert may now be any expression, and need no
  longer be an atom.

Fixed

• futhark fmt --check no longer prints the program on failure.

• Use of unsigned types in entry points could cause invalid C to be generated.
  (#2306)

• futhark script now frees values before terminating.

• Correct source locations when warning about unused local functions.

• Unpacking a unary sum type directly in a parameter or let-binding was
  defective. (#2314)

• The derivative of x**1 for x==0 would be NaN.

• futhark fmt now prints multi-line assert in a less horrible way.
