• jQuery Minified (29kb Gzipped)
• jQuery Regular (214kb)

修复的bug包括：

• #6158 Fixed replaceWith from throwing errors on non existent elements.
• #7340 We now use a single capturing handler to simulate bubbling focusin/focusout event on non-IE browsers. Allows native DOM methods to fire events other than the currently active one back into jQuery.
• #8353 Reverted. Adds a catch block in resolveWith so that the finally block gets executed in IE7 and IE6. Fixes #8438 – an issue where the full functions stack wasn’t visible when debugging in Google Chrome.
• #8380 Make it so that $(‘:text’) matches <input> as ‘type=text’ is the implied default.
• #8421 Makes sure resolveWith can be called with only one parameter.
• #8423 Never set X-Requested-With header automagically for cross-domain requests. Fixes an issue where all cross-domain ajax requests are pre-flighted and require extra additional options.
• #8456 Fixed an issue where trigger(‘mouseover’) was no longer triggering mouseenter. We make sure parent is not null before crawling into its lap, so mouseenter is triggered on a mouseover event.
• #8509 Makes URL regexp less overzealous and ensures it recognizes URL schemes which do not contain a conformant hierarchical structure (as per section 2.1.2 ofhttp://www.ietf.org/rfc/rfc2718.txt). Also adds about: and adobe air’s app: and app-storage: to the list of local protocols and provides a failover in case document.location is illformed.
• #8536 Introduced submodules to the jQuery repository on GitHub.
• #8381 Fixed .is(“div”) to work on disconnected nodes in IE 9.
• #8316 Fixed .offset() setter on fixed elements in WebKit.
• #3333 Fixed incorrect .css(“marginRight”) in WebKit.
• #8692 Fixed an issue where the arguments object sometimes ended up with undefined values outside the $.when method.
• #8346 Fixed a compatibility issue with jQuery.camelCase() and IE9 prefixes.
• #8203 Removed some unnecessary nulling of elements done in the name of an IE memory cleanup.
• #8519 Prevent the core makefile from applying minification if nothing in the code has actually changed.
• #8587 Fixed the jQuery-git.js cron-job to ensure that it is being regularly updated.
• #8635 Corrected an issue with Firefox 3.6 where an issue with getComputedStyle() was resulting in uncaught exceptions.
