jQuery 1.11.1 and 2.1.1 Released

Posted on by

Ah, the air is sweet with the scent of spring and new jQuery 1.11.1 and 2.1.1 are in bloom. These are minor patch releases and shouldn’t pose any major compatibility issues. Throw a Cinco de Mayo party and have your friends come over to test. If you dig up a problem, let us know at bugs.jquery.com, and be sure to provide a simple test case using jsfiddle.net or jsbin.com to demonstrate the problem.

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.


The Google and Microsoft CDNs will be getting their copies today just like you did, so please give them a few days to post the files and don’t be impatient. If you’re anxious to get a quick start, just use the files on our CDN until they have a chance to post.

Minified files (for production use) and map files (for debugging) are also available. If you want to use the map file for debugging the minified code, copy the minified file and add a //# sourceMappingURL comment to the end of the file.

Many thanks to all of you who participated in this release by testing, reporting bugs, or submitting patches, including Benjy Cui, Christian Kosmowski, Jason Frank, Julian Aubourg, Jens Simon, John Hoven, John Madhavan-Reese, Jonathan Sampson, Jörn Zaefferer, Leo Balter, Louis-Rémi Babé, Michał Gołębiowski, Oleg Gaidarenko, Philip Jägenstedt, R.G. Otten, Rhys Evans, Richard Gibson, Rick Waldron, Rob Graeber, Rodrigo Rosas, Roman Reiß, S. Andrew Sheppard, Scott González, and Timmy Willison.

Here are the changes since the last official releases (1.11.0 and 2.1.0):

    var foovalue = $(‘input:hidden[name=fooname]’).val();

    var foovalue = $(‘input[type=hidden][name=fooname]’).val();

    sourceMappingUrl needs to be sourceMappingURL to work in Chrome. The Download page has it correct.

  5. That’s amazing! I’ve been using it for long time and it saved lots of money and time while creating web sites. I wish I could help you in anyway to contribute with this great library and keep the good work.

    Most of my users are on IE8, but I’ve been instructed to develop for IE9 as we will be upgrading in the near future. I’m worried using the 2.x branch, users that have not been upgraded yet will have a poor experience. Is there a way I can utilize both the 1.11.x and 2.x libraries?

    K.doubleU: you can use conditional comments to load jQuery 1 in IE8 but I’d just use jQuery 1 as long as you need to support IE8, it’s safer.

  9. The Google AJAX and ASP.NET CDNs still do not have the updated version. Only one is cloudflare at cdnjs.com!
