WHAT’S NEW?
THE WRITE LESS, DO MORE, JAVASCRIPT LIBRARY
Aspects of the API that were changed in the corresponding version of jQuery. API changes in jQuery 1.7.0 dealt primarily with the new Event APIs: .on() and .off()
jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript.
Better Support for HTML5 in IE6/7/8
