I have read about using the noConflict option:

var jq132 = jQuery.noConflict();

I have also read in several places that it is best to avoid this option and stick to 1 Version per page.

If I were to go w/the latter option; can I simply stick with the newest version of jQuery and be OK w/the functionality of the page?

I expanding on a preexisting web site. The site is in WordPress (if that even matters), and uses jQuery 1.1.1. My script requires v1.8.3.  So my bottom line real question is this:

Does each version of jQuery build off the last, previous version? If so, then I'm assuming I would have no issues if I just ditched the older script and moved up to v1.8.3 for the entire site??? Or if nothing else, at lease on my page. My v1.8.3 only loads on my page as is, and no where else on the site.

Thanks,

Tracy
