In version 3.5.2 I used to initialize the plugin by setting its Language, so that every select would have automatically used the selected Language. I was doing it like this:
$.extend($.fn.select2.defaults, $.fn.select2.locales['it']);

In version 4.0.0 I've seen that I can specify the Language in every call to the select2 plugin by setting the "Language" parameter to the desired Language.
My question is: is there a way, in version 4.0.0, to set the default Language once so that it would be common to all select2 that will be created? Like I was doing in version 3.5.2
