Added a new liveQuery/event delegation hybrid method: .live and .die. Easily adapts event delegation to the jQuery style. $("div").live("click", fn); $("div > #foo").live("submit", fn); $("div").die("click");

Added the new jQuery.support object and removed all uses of jQuery.browser from within jQuery itself (while simultaneously deprecating the use of jQuery.browser).

Fixed an issue with domManip where the incorrect document was being used to create the document fragment.

Landing the new Sizzle selector engine. There'll need to be some later tweaks (to make the tests a little more pragmatic - especially for document order elements). But it appears to be passing well and that's enough. Closes #3563.

Rewrote the hide and show methods to fix the issue with Safari not hiding distached elements. Fixed #1239, #2233, #3038, #3343, #3395. They're also faster now, as well.

Fixed an issue with how .data() was expecting output (trigger now returns exact output - or null if none is provided, which was tripping it up).

The code for handling Ajax timeouts was broken (the abort was being called too early). Fixing this allows the test suite to work again.

Standardized the type checks across core. isFunction and isArray now use Object.prototype.toString to verify the type, .constructor use was removed in favor of typeof, typeof checks now use ===, undefined checks use === undefined. All of this is outlined in the new style guidelines: http://docs.jquery.com/JQuery_Core_Style_Guidelines#Type_Checks. Fixes bug #3618.

Landing fixes for tickets #2935 and #2688 (Aborting ajax doesn't stop the setInterval, ajaxStop event isn't getting triggered).

Landed the patch, by Diego, that 1) Removes browser sniffing from the ready code and 2) Provides some form of fallback DOM Ready for Iframes in IE. Closes #2614.

core: height() method wasn't working reliably in Opera - rather than returning the actual client height when called on window, it returned the document's height through document.body.clientHeight. The right value to work with is html.clientHeight

core: tests cleanup for compability with qunit updates: stop() now actually accepts an argument (ajax.js); selectors should be confined to fixture(event.js)
