jQuery 1.9 - reporting reliance on a deprecated feature

I upgraded to jQuery 1.9 and jQuery UI 1.10 last week. I also installed the jQuery Migrate plugin to assist with the transition as quite a few previously deprecated features have now been removed.

I get a warning in "jquery/event/hashchange/hashchange.js", which relies on jQuery.browser (that is now removed). Ben Alman doesn't appear to have put out an updated version of the plug in yet.

I'm not suggesting any specific action, just calling attention to it.
