- simplified definition of the classes: removed the getters, setters and designers;
- optional parameters with default values;
- Named arguments and “object builder” syntax;
- types of intersections (intersection types), types of association (union types) and fundamental types (bottom types);
- static checking null-values, and empty sequences;
- covariance and contravariance in the declarations instead of wildcard types;
- more elegant syntax for type constraints (type constraints);
- top-level function, and a declaration of values instead of the static members of nested functions;
