jQuery 3.7.0 is now available! This release has it all: bug fixes, a new method, and a performance improvement! We even dropped our longtime selector engine: Sizzle. Or, I should say, we moved it into jQuery. jQuery no longer depends on Sizzle as a separate project, but has instead dropped its code directly into jQuery core. This helps us prepare for the major changes coming to selection in future

You probably weren’t expecting another release so soon, but jQuery 3.6.2 has arrived! The main impetus for this release was the introduction of some new selectors in Chrome. More on that below. As usual, the release is available on our cdn and the npm package manager. Other third party CDNs will probably have it soon as well, but remember that we don’t control their release schedules and they will

jQuery 3.6.1 has been released! It’s been a while since our previous release. We were looking at fixing some elusive edge cases related to focus and blur, but we never quite got the fix right. If there’s any area of jQuery that’s hard to change, it’s likely related to focus somehow. We’re leaving those as-is for now and will address them in the future, especially since the changes may end up warra

jQuery 3.6.0 has been released! In jQuery 3.5.0, the major change was a security fix for the html prefilter. This release does not include a security fix, but does have some good bug fixes and improvements. We still have our eyes on a jQuery 4.0 release, but until then we will continue to support the 3.x branch and address important issues. As usual, the release is available on our cdn and the npm

I’ve never gotten to say this on a jQuery release, but May the 4th be with you! A short time ago in a galaxy exactly like this one, we released jQuery 3.5.0. We have a quick fix for a regression in that release. Specifically, we had changed our internal data object to use Object.create( null ) instead of a plain object ({}). We did that to prevent collisions with keys on Object.prototype propertie

jQuery 3.5.0 has been released! As usual, the release is available on our cdn and the npm package manager. Other third party CDNs will probably have it soon as well, but remember that we don’t control their release schedules and they will need some time. We hope you’re staying healthy and safe while so many of us are stuck at home. With a virus ravaging the planet, we realize that jQuery may not b

jQuery 3.4.1: triggering focus events in IE and finding root elements in iOS 10 Hello again! jQuery 3.4.0 was released just three weeks ago, but we’ve had a few issues reported that warranted a patch release. Thank you to everyone that reported issues and helped us get these fixed quickly. Here are the changes: Triggering focus or blur more than once in IE jQuery 3.4.0 came with some changes to th

jQuery has a new release! It’s been a while since our last release, but we expect this to be the last minor release in the 3.x branch, and then we will move on to the overhaul that will be jQuery 4.0. But before we get to 4.0, we’re excited to share the bug fixes and improvements included in jQuery 3.4.0. Here are some of the highlights: Performance improvement in .width and .height When getting a

jQuery 3.3.0 – A fragrant bouquet of deprecations and…is that a new feature? It’s been a while since the last jQuery release, but the Core team hasn’t been idle. We’ve got an all new minor release for you, and it’s even got a new feature in it! The .addClass(), .removeClass(), and .toggleClass() methods now accept an array of classes. jQuery(elem).addClass([ 'dave', 'michał', 'oleg', 'richard', 'j

jQuery 3.2.0 has been released! This release includes some bug fixes, improvements, and some deprecations. There should be no compatibility issues if upgrading from jQuery 3.0+. If you haven’t yet upgraded to jQuery 3+, please have a look at the 3.0 Upgrade Guide. The jQuery Migrate 3.0 plugin will help you to identify compatibility issues in your code. Please try out this new release and let us k

jQuery 3.1.1 is now available! This release includes some bug fixes and improvements. As with all patch version releases, there are no new features or intended compatibility issues (if upgrading from jQuery 3.0+) in this release. We fixed a selector issue with disabled options, exposed jQuery.noConflict even when jQuery is loaded with AMD, and fixed some issues concerning whitespace. We also fixed

Not so long ago, we released jQuery 3.0. One of the major features of jQuery 3.0 was a small rewrite of jQuery Deferreds. Specifically, we made them compatible with the Promises/A+ spec. That basically meant that errors had to be silenced and passed as rejection values to rejection handlers (added using deferred.catch()). This had the advantage of preventing Promise handlers from getting blocked u

jQuery 3.0 is now released! This version has been in the works since October 2014. We set out to create a slimmer, faster version of jQuery (with backwards compatibility in mind). We’ve removed all of the old IE workarounds and taken advantage of some of the more modern web APIs where it made sense. It is a continuation of the 2.x branch, but with a few breaking changes that we felt were long over

Welcome to the Release Candidate for jQuery 3.0! This is the same code we expect to release as the final version of jQuery 3.0 (pending any major bugs or regressions). When released, jQuery 3.0 will become the only version of jQuery. The 1.12 and 2.2 branches will continue to receive critical support patches for a while, but will not get any new features or major revisions. Note that jQuery 3.0 wi

After last week’s announcement that JSCS is merging with ESLint, this week the ESLint team is announcing that they are bringing their project to the jQuery Foundation. We are very excited to be the providers of a long-term, openly governed home for ESLint. We are also looking forward to seeing the outcomes of this new partnership with JSCS. At the Foundation, we are constantly striving to find way

As the jQuery team prepares for a 3.0 final release, we continue to maintain the 1.12 and 2.2 branches. These two patch releases fix a few bugs and improve stability. The most significant bug fix involved a problem with the .position() method, which affected how jQuery UI tooltips were positioned in Internet Explorer. We do not expect this release to have any breaking changes, but if you do encoun

On the 14th of January 2006, John Resig went to an event called BarCamp NYC to talk about some of the projects he was working on. One of those projects was a JavaScript Library called jQuery. It was the birth of what has become the most widely used JavaScript library ever written. It’s hard to imagine now, but there were already about a dozen JavaScript libraries around on that day when John annou

To usher in the new year, the jQuery team has been hard at work on 2 new releases: jQuery 1.12.0 and 2.2.0! These releases include lots of bug fixes and improvements to make your cross-browser development experience better. We anticipate this to be the last releases for the 1.x and 2.x branches before we release jQuery 3.0. Since jQuery 3.0 will have some breaking changes, we will continue to supp

Grunt is one of the best-known and most popular task runners in the web developer’s toolkit. Now that this project has joined the jQuery Foundation, we’re looking to get the project rolling again. Ben Alman, the creator of Grunt, is looking for contributors who can take over the reigns. The team could use some help with triaging a stack of issues and pull requests, then getting a new release out t

United Foundation to Advance the Open Web by Serving Developers The jQuery Foundation and Dojo Foundation today announce plans to combine forces to form the largest, most diverse and most comprehensive Foundation committed to building the Open Web by serving developers, their projects and their communities. “This merger elevates Web accessibility, openness and developer education, and will advance

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 actua

Here we are again. It’s too late for April Fools, so you can believe us when we tell you that we have two new patch releases for you: jQuery 1.11.3 and 2.1.4. These releases include a hot-fix for a rare bug in iOS 8.2 and 8.3. This is the only change. As with 1.11.2 and 2.1.3, we do not anticipate any issues when upgrading. However, if you do encounter bugs in upgrading from the previous versions,

The jQuery Foundation is excited to announce the 1.0 release of the Globalize project, our internationalization (i18n) library. This release has been a long time coming and as Globalize picks up steam and gains more and more adoption every day, we are proud to finally announce the first stable release of this project. We could go on about the features and benefits of this latest release but we fel

Today, we’re happy to announce the first release of PEP (jQuery Foundation’s Pointer Events polyfill) since Google transferred the Pointer Events polyfill to the jQuery Foundation. There’s more work to do in order to address changes to the Pointer Events specification and flesh out our test suite, but you can start using Pointer Events in your projects today! Other projects, like jQuery UI, jQuery

We’ve just released Esprima 2.1.0! This release introduces support for several new pieces of ES6 syntax: Classes, Rest Parameters, Computed Property Names, let and const. See the release notes below for full details. We’ve also made various improvements to our testing infrastructure to make the codebase more contributor friendly. A big thank you to all those who contributed patches to this release

We’re excited to announce that the Pointer Events specification has become a W3C Recommendation! As we’ve said before, we love Pointer Events because they support all of the common input devices today – mouse, pen/stylus, and fingers – but they’re also designed in such a way that future devices can easily be added, and existing code will automatically support the new device. While reaching Recomme

Last week, the jQuery Foundation announced our adoption of the Esprima project, the widely used JavaScript parser that powers many code analysis tools. Today we’re pleased to announce the release of version 2.0, now available on npm. Up until now, the official releases of Esprima have only parsed ECMAScript 5 standard syntax. However, the experimental “harmony” branch has been adding ECMAScript 20
