[10.2.0] - 2018-04-15

Added

• Map/set methods which accept references to keys will now also take
  any value that's borrowable to the key's type, ie. it will take a
  reference to a type Borrowable where the key implements
  Borrow<Borrowable>. This is particularly handy for types such as
  String because you can now pass &str to key lookups instead of
  &String. So, instead of the incredibly cumbersome
  map.get(&"foo".to_string()) you can just do map.get("foo") when
  looking up a mapping for a string literal.
