Google Maps API v3 doesn't support "hl" param yet? -

As I tried "tag", returned javascript content still shows N-US for "HL" param . It seems that so far the V3 API does not support the local language. Is it true?

The localization parameter has changed to v3. You should read.

Actually, instead of hl , you should use the language . And here's also a new area setting, everything is in the link documentation.
