jQuery 1.12.1 and 2.2.1 Released

February 22nd, 2016

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 encounter bugs in upgrading from the previous version, please let us know.


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 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.
