Popular Ajax library jQuery is celebrating its fourth birthday with a major new release — JQuery 1.4.
The latest version of jQuery boasts some impressive speed gains and represents a ground up refactoring of much of jQuery’s underlying code. According the jQuery’s developers this release is significantly faster across browsers and eliminates much of the redundancy in jQuery’s internal functions.
Other nice changes in this release include support for HTML5 elements in serialization calls, the ability to test for specific rendering engines (for example, target WebKit with
jQuery.browser.webkit) and support for per-property easing in your animations.
