  • Likely backwards compatibility. Many themes and plugins rely on the bundled version of jQuery, and 3.x (and probably 2.x) introduces breaking changes that would cause these themes and plugins to break.

    If do an audit in Chrome Developer Tools for WordPress 4.9.8 it reports that jQuery 1.12.4 contains a known security vulnerability.
