Previous releases had a bug that caused city name to be used when normalizing a city area name.
Validation rules now return a unique list of choices for `country_area_choices`, `city_choices` and `city_area_choices` where previous version would return a list of all existing translations resulting in duplicate values where spelling was identical.
For example the province list for Canada will now result in the following `country_area_choices`:
