Hi, At https://issues.apache.org/jira/browse/WICKET-5208 you may see a simple patch that makes JQueryResourceReference more dynamic. With this change Wicket can deliver jQuery 2.x to modern browsers and jQuery 1.x for IE 6/7/8.
Pros: smaller jQuery Cons: dynamic calculation by using the user agent to make the decision. Do you think this is useful/problematic ? The user application still can set its own ResourceReference with jQuery version that it prefers.
