 ### Bug Fixes
 
-* Use `:other` plural category to format units which have a value of 0, 1 or 2 when the natural unit pattern has no substitutions. This corrects the situation in locales such as `he` and `ar` where the unit pattern for plural category `:one` has no substitutions. Previously this would means the formatted string for a unit with a vaue of `1` and `-1` would both output the same string.  Thanks to @jarrodmoldrich for the report and to @voltone for his family's help with hebrew grammar.

-* Adds a `:per` option to `Cldr.Unit.to_string/3`. This option leverages the `per` formatting style to allow compound units to be printed.  For example, assume want to emit a string which represents "kilograms per second". There is no such unit defined in CLDR (or perhaps anywhere!). But if we define the unit `unit = Cldr.Unit.new(:kilogram, 20)` we can then execute `Cldr.Unit.to_string(unit, per: :second)`.  Each locale defines a specific way to format such a compount unit.  Usually it will return something like `20 kilograms/second`
