What to upgrade to

Go to 4.

4 is the newest supported jQuery cycle.

Before you upgrade

Load jQuery Migrate during the upgrade: it logs every removed API your code and plugins still call. WordPress ships its own copy; update WordPress rather than swapping it. Read the jQuery 4 upgrade guide

How to check your version

Which jQuery is this site on?

In the browser

$ jQuery.fn.jquery
"3.7.1"
# in the console on any page that loads it

In the lock file

$ npm ls jquery
# or the version in a CDN script tag

Know before support ends.

Porro reads the PHP, framework and database version from every site and tells you 90 days before support runs out.
