0.5.1

Added

• Entry points need no longer be syntactically first-order.

• Added overloaded numeric literals (#532). This means type
  suffixes are rarely required.

• Binary and unary operators may now be bound in patterns by
  enclosing them in parenthesis.

• futhark-doc now produces much nicer documentation. Markdown is
  now supported in documentation comments.

• /futlib/functional now has operators >-> and <-< for
  function composition. <<| are |>> are deprecated.

• /futlib/segmented now has a segmented_reduce.

• Scans and reductions can now be horizontally fused.

• futhark-bench now supports multiple entry points, just like
  futhark-test.

• ".." is now supported in include paths.

Removed

• The reshape construct has been removed. Use the
  flatten/unflatten functions instead.

• concat and rotate no longer support the @ notation. Use
  map nests instead.

• Removed -I/--library. These never worked with
  futhark-test/futhark-bench anyway.

Changed

• When defining a module type, a module of the same name is no
  longer defined (#538).

• The default keyword is no longer supported.

• /futlib/merge_sort and /futlib/radix_sort now define
  functions instead of modules.

Fixed

• Better type inference for rearrange and rotate.

• import path resolution is now much more robust.
