+
+**Important changes**
+- `Subdivision` now has a `type` attribute obtained from ISO3166-2 subdivision types. `type` is a _lowercase_ and _snake_cased_ string.
+- Adds `Country#subdivision_types` and `#humanized_subdivision_types` to list a country's subdivision types
+- Adds `Country#subdivisions_of_types(types)` to allow getting subdivisions of given type(s)
+- `Country#states` is now deprecated to avoid confusion (this method was just an alias to `#subdivisions` and retuns all subdivisions, regarless of type)
