jQuery is a JavaScript library created to simplifies HTML document traversing, event handling, animating as well as Ajax interactions.
Version 1.4.4 has just been released. It features several bug fixes and also some improvements.
The function .fadeToggle() has been added. .fadeToggle() does not only fades HTML elements in and out. It sets the CSS display value of an element to 'none' after fading it out, so it does not affect the rest of the layout when it is not visible.
