JQuery is a bit out of date. It's currently at 2.2.4, which was the last version released in the 2.x series. Versions prior to 3.x are no longer receiving patches, and have known bugs.
We should update to the latest versions to avoid bundling any versions which may have known bugs. The latest version is currently 3.2.1.
(Note: I've checked flot, jquery-ui, select2, and bootstrap, and we are currently using the latest versions of all of those right now. Along with jQuery, that is an exhaustive list of our external monitor resources.)
