jQuery 1.12.2 and 2.2.2 Released

Posted on by

We’re keeping the releases coming with two new patch releases for the 1.x and 2.x branches. These releases include a few bug fixes, which includes two edge case bugs for jQuery.isPlainObject and a bug when setting the selected property on an option element using the .prop() method in IE 11.

We do not expect this release to have any breaking changes, but if you do encounter bugs in upgrading from the previous version, please let us know.

We’ll have a release candidate of jQuery 3.0 very soon.

You can include these files directly from the jQuery CDN if you like, or copy them to your own local server. The 1.x branch includes support for IE 6/7/8 and the 2.x branch does not.



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 Michał Gołębiowski and Richard Gibson and the whole jQuery team.

  1. Thanks for the update, and the work by those that have contributed to this great project over the years. I am curious to how the jQuery performs on a mobile browser right now. Are the references in the above comments towards performance referring to a browser on desktop/laptop computer or mobile browser? Where is a good place to test the performance for jQuery on your own?
