Description: 

Drupal 8.x now ships with jQuery 1.7.

The jQuery 1.7 release notes can be found over at http://blog.jquery.com/2011/11/03/jquery-1-7-released/

In addition to updates introduced during jQuery 1.5 and 1.6, in jQuery 1.7 it is now recommended to use the .on and .off methods instead of using .bind/.unbind

Also there is now a prop attribute in jQuery (introduced in 1.6) which is used to get the property of an element instead of using attr (Which should be used for getting an actual html attribute, ex. attribute="test')

Module or distribution developers who previously required the jquery_update module to use jQuery 1.7 functionality can remove the module as a dependency.
