Jquery 1.7 - A New Event API's
Jquery 1.7 was out (about a +week ago).
This version introduces new Event APIs for binding and unbinding events (both DOM and Custom).
The jquery team encourages using the new Event APIs rather than the old ones – bind/delegate/live.
The old ones are still there – but will be deprecated in a later version.
The “on” API documentation page (for binding events) is quite thorough and explains how to achieve the old apis (bind/delegate/live) with “on”.
Due to high usage of the “delegation” pattern, in this version, jquery team says they refactored its library for better & faster performance on delegated events.
Converting your code to the new API should be quite easy, and the documentation page details easy and straight forward examples.
