It depends from your target audience, and therefore from the browsers you need to support.
You have three options:
- If you need to support older browsers like Internet Explorer 6-8,
Opera 12.1x or Safari 5.1+, use: jQuery 1.11.3 + jQuery Mobile 1.4.5 - If you need the current stable and most used pair, use: jQuery 2.1.4 + jQuery
Mobile 1.4.5 - If you are living on the edge, and would like to actively take part to the
jQuery Mobile development, notify bugs and open issues on github,
use: jQuery 3.2.1 + jQuery Mobile 1.5.0-alpha.1
