There are many things that I love about Drupal, but they way it incorporates jQuery is not one of them. Drupal 7 core comes with, and is tied to, a particular version of jQuery – 1.4.4. That came out in November of 2010. Since then, from a jQuery perspective, Drupal has been frozen in time.
“But wait,” you say, “what about the jQuery Update module?” That is true, that module will do the job, but in a lot of situations, at too much of a cost. jQuery Update replaces jQuery across the whole site – which, unfortunately, breaks a lot of site admin tasks. Check the issue queue for proof.
