//Param serialization now happens in the PHP/Rails style by default. You can use jQuery.ajaxSettings.traditional = true; to use traditional parameter serialization. You can also set the behavior on a per-request basis by passing traditional: true to the jQuery.ajax method.

$.param( {foo: ["bar", "baz"]} ) === “foo=bar&foo=baz”.
