I've been having an issue where jQuery v1.9.1 is being included into the top of the gtm.js file. It causes a few issues and can blow away jQuery plugins that are already loaded on jQuery.fn. Regression testing is also a concern. I checked and I don't appear to have any custom tags in the Google Tag Manager that loads jQuery.
Ultimately I want to have control over the host domain and version of jQuery loaded. Is there a configuration setting in the GTM interface or some other way that I can disable the inclusion of jQuery?
I'm pretty sure that the jQuery code that is included in gtm.js is customized and not globally available.
I did a quick test, and neither jQuery nor $ are defined when I just insert the GTM snippet into a page.
(window.$ actually is defined, but that's a Chrome thing: Commandline API Reference)
