jQuery API ChangeList (1.3.2 to 1.6.2)

Submitted by admin on

The jQuery Cookbook (2010 O"Reilly) is great, but with the rapid advance of the jQuery API it is already becoming outdated. The cookbook covers jquery 1.3.2 and as of the time of this writing, the current API version is 1.6.2. Similarly, the version of jQuery that ships with Drupal 7 is just 1.4.4.

Newer versions of jQuery offer improved performance and should be used on fresh projects. Version 1.5 has the main addition of deferred callback management. It is important to stay up to date with the new features of jQuery. Here is a list of all new API methods:
