It’s been a long time since we did a major release, and you certainly deserve one. So we’re glad to announce the first alpha of jQuery 3.0!
Despite the 3.0 version number, we anticipate that these releases shouldn’t be too much trouble when it comes to upgrading existing code. Yes, there are a few breaking changes that justified the major version bump, but we’re hopeful these breakages don’t actually affect that many people. The jQuery Migrate plugin can help you to identify compatibility issues in your code as well. Your feedback on the changes in this alpha will help us greatly, so please try it out on your existing code and plugins!
There are actually two releases here. First is jQuery 3.0, which supports modern browsers and environments from IE9 forward. Second is jQuery Compat 3.0, which includes support for IE8. As an added bonus, both jQuery and jQuery Compat will include support for Yandex.Browser, a freeware browser released in 2012. You can get the files from the jQuery CDN, or link to them directly:
https://code.jquery.com/jquery-3.0.0-alpha1.js
https://code.jquery.com/jquery-compat-3.0.0-alpha1.js
You can also get the alpha versions from npm:
npm install jquery@3.0.0-alpha1
npm install jquery-compat@3.0.0-alpha1
Major changes
Below are just the highlights of the major new features, improvements, and bug fixes in these releases. A complete list of changes is available at the bottom of this post and on our GitHub issue tracker. On GitHub, you can additionally see the features we expect to put in later beta and final versions that have yet to land.
Simplified .show() and .hide() methods
Everyone’s mental model of jQuery’s .hide() method is that it sets display: none in CSS. Conversely, .show() clears the display so that the element shows again (assuming its parents are not hidden). Simple, right?
Well, no. There are actually many complex special cases that people asked us to “fix” over the years, which turned these methods into a convoluted confluence of principles. For example, what if the element is set to display: none in a stylesheet? jQuery would try to override that by forcing display: block on the element directly. Okay, but what if a normally block element like <li> was set to display: inline by a different stylesheet rule? How about the case where you call these methods on an element before it’s been added to the document and we don’t know what display value it will have? Determining all of that takes extra work. Sometimes it’s still just a guess that turns out to be wrong.
Since these methods add a style attribute to the element, they don’t tend to play well with techniques like responsive design where the visibility of elements may also be set by media queries. This leads to the need for jQuery handlers that listen for the orientationchange or resize events and manually hide or show parts of the page; it defeats the elegant solution that media queries were trying to implement.
You can see that jQuery was already about halfway down the path to total madness, and it didn’t make sense to complete the journey. The special cases and checks were not only complex and incomplete, but they caused significant performance issues on large pages.
So, instead, we’re experimentally defying the evolution of these methods and reverting to a simple, primordial model. This will break some code. If you have elements in a stylesheet that are set to display: none, the .show() method will no longer override that. So the most important rule for moving to jQuery 3.0 is this: Don’t use a stylesheet to set the default of display: none and then try to use .show() – or any method that shows elements, such as .slideDown() and .fadeIn() – to make it visible.
If you need an element to be hidden by default, the best way is to add a class name like “hidden” to the element and define that class to be display: none in a stylesheet. Then you can add or remove that class using jQuery’s .addClass() and .removeClass() methods to control visibility. Alternately, you can have a .ready() handler call .hide() on the elements before they are displayed on the page. Or, if you really must retain the stylesheet default, you can use .css("display", "block") (or the appropriate display value) to override the stylesheet.
We know that this is likely to be one of the most contentious and difficult changes in jQuery 3.0, so we wanted to put it out in this early release to see the effects. Please let us know how it affects your code and what you need to change in order to work with this new model.

Special case with .data() names
We have updated our .data() implementation to closer match the HTML5 dataset specification. All keys are now converted from kebab-case to camelCase, regardless of access method, and digits no longer participate in the conversion. For example, we will no longer differentiate between “foo-bar” and “fooBar”, but will differentiate between “foo-42” and “foo42”. These changes will mainly come into play when retrieving all data by calling .data() with no arguments, or when trying to access the data using a converted key (.data(“foo42”)) instead of the original (.data(“foo-42”)).
https://github.com/jquery/jquery/issues/1751
jQuery.Deferred is now Promises/A+ compatible
jQuery.Deferred objects have been updated for compatibility with Promises/A+ and ES2015 Promises, verified with the Promises/A+ Compliance Test Suite. This meant the introduction of a .catch() method and some major changes to the .then() method:
- An exception thrown in a
.then() callback now becomes a rejection value. Previously, exceptions bubbled all the way up, aborting callback execution and irreversibly locking both the parent and child Deferred objects.
- The resolution state of a Deferred created by
.then() is now controlled by its callbacks—exceptions become rejection values and non-thenable returns become fulfillment values. Previously, returns from rejection handlers became rejection values.
- Callbacks are always invoked asynchronously. Previously, they would be called immediately upon binding or resolution, whichever came last.
- Progress callbacks can no longer resolve Deferred objects to which they are bound.
Consider the following, in which a parent Deferred is rejected and a child callback generates an exception:
var parent = jQuery.Deferred();
var child = parent.then( null, function() {
return "bar";
});
var callback = function( state ) {
return function( value ) {
console.log( state, value );
throw new Error( "baz" );
};
};
var grandchildren = [
child.then( callback( "fulfilled" ), callback( "rejected" ) ),
child.then( callback( "fulfilled" ), callback( "rejected" ) )
];
parent.reject( "foo" );
console.log( "parent resolved" );
As of jQuery 3.0, this will log “parent resolved” before invoking any callback, each child callback will then log “fulfilled bar”, and the grandchildren will be rejected with Error “baz”. In previous versions, this would log “rejected bar” (the child Deferred having been rejected instead of fulfilled) once and then immediately terminate with uncaught Error “baz” (“parent resolved” not being logged and the grandchildren remaining unresolved).
While caught exceptions had advantages for in-browser debugging, it is far more declarative (i.e. explicit) to handle them with rejection callbacks. Keep in mind that this places the responsibility on you to always add at least one rejection callback when working with promises. Otherwise, any errors will go unnoticed.
Legacy behavior can be recovered by replacing use of .then() with the now-deprecated .pipe() method (which has an identical signature).
jQuery.when has also been updated to accept any thenable object, which includes native Promise objects.

https://github.com/jquery/jquery/issues/2102
Removed special-case Deferred methods in jQuery.ajax
jqXHR object is a Promise, but also has extra methods like .abort() so that you can stop a request after it has been made.
As users increasingly embrace the Promise pattern for asynchronous work like AJAX, the idea of having special cases for the Promise returned by jQuery.ajax is an increasingly bad idea.
success, error, complete
done, fail, always
Note that this does not have any impact at all on the callbacks of the same name, which continue to exist and are not deprecated. This only affects the Promise methods!
https://github.com/jquery/jquery/issues/2084
Error cases don’t silently fail
Perhaps in a profound moment you’ve wondered, “What is the offset of a window?” Then you probably realized that is a crazy question – how can a window even have an offset?
In the past, jQuery has sometimes tried to make cases like this return something rather than having them throw errors. In this particular case of asking for the offset of a window, the answer up to now has been { top: 0, left: 0 } With this alpha of jQuery 3.0 we’re experimenting with the idea of having such cases throw errors so that crazy requests aren’t silently ignored. Please try the alpha and see if there is any code out there depending on jQuery to mask problems with invalid inputs.
https://github.com/jquery/jquery/issues/1784
.width(), .height(), .css(“width”), and .css(“height”) to return decimal values (whenever the browser does)
Previously, jQuery rounded values when retrieving width and height. Some browsers return subpixel values – such as IE and Firefox – and sometimes users need this precision when relying on these values for layout. We don’t expect this change to have a big impact on your code, but let us know if it does.
https://github.com/jquery/jquery/issues/1724
Removed deprecated event aliases
.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.
https://github.com/jquery/jquery/issues/2286
jQuery.swap, jQuery.buildFragment, and jQuery.domManip are no longer accessible on the jQuery object
These methods were always intended for internal use only and were never documented. We are finally making them private to avoid confusion.
https://github.com/jquery/jquery/issues/2224
https://github.com/jquery/jquery/issues/2225
Animations now use requestAnimationFrame
On platforms that support the requestAnimationFrame API, which is pretty much everywhere but IE8 and IE9, jQuery will now use that API when performing animations. This should result in animations that are smoother and use less CPU time – and save battery as well on mobile devices.
jQuery tried using requestAnimationFrame a few years back but there were serious compatibility issues with existing code so we had to back it out. We think we’ve beaten most of those issues by suspending animations while a browser tab is out of view. Still, any code that depends on animations to always run in nearly real-time is making an unrealistic assumption.
.unwrap( selector )
Before jQuery 3.0, the .unwrap() method did not take any arguments. The selector parameter offers a way to be specific about which wrappers to remove.
https://github.com/jquery/jquery/issues/1744
Massive speedups for some jQuery custom selectors
Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!
Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.
