详细改进内容：

• (New) Added a new animation method, .fadeToggle()
• (Enh) Calling .data() with no arguments now includes data from HTML5 data- attributes ( #7222 )
• (Enh) Moved jQuery.props from support.js to attributes.js ( #6897 )
• (Enh) .width() and .height() now report the width and height of hidden elements ( #7225 )

• (Bug) Limited the scope of the CSS ‘auto’ change to just height/width ( #7393 )
• (Bug) Fixed a bug to ensure that unquoted attribute selectors are quoted (allowing them to go into qSA/matchesSelector properly). Fixes ( #7216 )
• (Bug) Fixed a bug to ensure that if additional load events are triggered (eg. an iframe being dynamically injected in DOM ready) the ready event isn’t triggered twice ( #7352 ).
• (Bug) Fixed a condition that prevents attr from working on non-Element nodes ( #7451 ).
• (Bug) Changing an HTML5 data attribute after calling .data(‘foo’) no longer causes .data(‘foo’) to also change ( #7223 )
• (Bug) Fixed a bug where Opera didn’t give height/width of display: none elements with getComputedStyle but did with currentStyle – fall back to that if it exists added.
• (Bug) Fixed a bug to ensure accessing computed CSS for elements returns ‘auto’ instead of ” consistently ( #7337 )
