Localization
You can localize your Maps JavaScript API application by changing the default language settings and by specifying a region code, which alters the map's behavior based on a given country or territory. Read about localizing the map.
Versioning
The Maps JavaScript API team regularly updates the API with new
features, bug fixes, and performance improvements. You can indicate which
version of the API to load within your application by specifying it in the
v parameter of the Maps JavaScript API bootstrap
request. Read more about
versioning.
