What is jQuery?
You can link to the latest and most update jQuery through the Google API Libraries.
Using the Google AJAX Libraries content delivery network to serve your jQuery directly from Google’s network of datacenters has a number of advantages over hosting jQuery on your website from: decreased latency, increased parallelism, and better caching.
There are a couple of ways you can load jQuery and other Libraries into your website via the google method.
jQuery is always evolving and if you choose to use the latest version of jQuery please keep up to date with the changes made. As an example in 1.7 .live() has been depreciated for the .on() event handler.
