Where is jQuery being loaded from?

[pmacMaps]

I wanted to check which version of jQuery is being used in this template? In some other non-storymap apps I've developed, I've had to update the version of jQuery due to some security issues. I wanted to see if Esri has done the same thing.

All I can find in the various app files is a reference to lib-app/jquery. But I can't find the URL for where jQuery is being loaded.
