I found recently the jQuery in our global includes folder is a really old version and doesn't work with some of the new .NET plugins. You can disable the built in jQuery with
data-psnoautojq="true"
Link to external Jquery CDN and use the above flag to not include our core one.
We should look into testing newer versions of our globalincludes (jquery, lightbox, sliderloader etc)and make them available. Jquery 2 and 3 don't support IE8 and below.

We need to consider the impact of this as lots of different sites will be running different versions of JQuery. Ideally the core plug-ins should be isolated from the rest of the site to avoid conflicts.
