Most current version of json

Most current version of json

In a vb.net 2010 web form application, I am in the process of obtaining all the most current jquery references that includes the jquery version 3.2.1.

As part of this process, I want to see if I am using the most current json references for json2.js.

When I click on the links that are listed below, I get the 404 server error where the link can not be located.

Thus can you tell me if I have the most current version of the json.js file? If not, would youi tell me where I can obtain the most current version of the jason code from and what the most current version of the json file is?
