jQuery 3.2.1 Is Now Available, With Some Hotfixes

Posted on by

jQuery 3.2.1 is now available! This release comes with some hotfixes for regressions that were introduced in the 3.2.0 build four days ago. We wanted to release this patch as quickly as possible to squash any bugs you may have experienced when upgrading. The most significant one had to do with retrieving width or height on an inline element with no explicitly-set dimensions. This should now work as expected. A full list of changes is available below. Also see the 3.2.0 blog post for the bug fixes and improvements that still apply if upgrading from jQuery 3.1.1.

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 know about any issues you experienced.



  • Ensure jQuery.holdReady is in the right place (#3573, fcc9a9ec)


  • Ensure we get proper values for width and height on elements with display “inline” (#3571, 473d2ea7)


  • Ensure trigger data is passed to radio click event handlers (#3579, a6b07052)
  • Revert: Trigger checkbox and radio click events identically (35785a32).
  • Revert: Add radio click triggering tests (4d6b4536).

You can get the files from the jQuery CDN, or link to them directly:



You can also get this release from npm:

npm install jquery@3.2.1

Slim build

Sometimes you don’t need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests. And often it is simpler to use a combination of CSS and class manipulation for all your web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we’ve released a “slim” version that excludes these modules. The size of jQuery is very rarely a load performance concern these days, but the slim build is about 6k gzipped bytes smaller than the regular version – 23.6k vs 30k. These files are also available in the npm package and on the CDN:


These updates are already available as the current versions on npm and Bower. Information on all the ways to get jQuery is available at https://jquery.com/download/. Public CDNs receive their copies today, please give them a few days to post the files. If you’re anxious to get a quick start, use the files on our CDN until they have a chance to update.


Many thanks to all of you who participated in this release by testing, reporting bugs, or submitting patches, including Steve Mao and the whole jQuery team.

  1. Is it possible that jQuery’s separate functionality (AJAX, CSS, etc.) is modularised and available on NPM so one could build their own custom version, kind of like lodash?
