jQuery 1.7.2 RC1 Released

March 9th, 2012

jQuery 1.7.2 will be arriving soon! To make sure that we’ve fixed the bugs voted “Most Likely to Annoy” without introducing any new bugs, we need your help in testing this release candidate. You can get the code from the jQuery CDN:

It will only take a few minutes to drop in this latest file and test it with your code. If you’ve got a lot of pages, the list of fixed bugs below may be a helpful guide for determining what to test. And of course, if you reported a bug or were affected by one listed below, please re-test to be sure we fixed it for good. We’ve tested it internally against the current builds of jQuery UI and jQuery Mobile. There is one compatibility issue with jQuery Mobile 1.1 RC1 that has already been fixed and will be addressed by their next release.

Looking for an even easier way to test your web site with the latest jQuery? On Windows you can use the excellent Fiddler tool and create an AutoResponder rule to point your HTTP script requests for jQuery to the file location above. Then you are testing your live web site with the latest jQuery on your PC, without having to edit any files at all! If you know of similar tools for other platforms, leave a message in the comments below.

If you are particularly interested in IE6 support, please help us out. We are having sporadic trouble running the unit tests in IE6. It hasn’t been possible for us to determine the cause of these problems, but the problem doesn’t happen consistently and the sheer size of our test suite may just be overwhelming a browser that is more than a decade old. If you observe any reproducible failures in real code, please let us know and try to provide the smallest possible test case.

You can use the bug tracker to report bugs; be sure to create a test case on jsFiddle so we can figure it out easily. If you’re not sure it’s a bug, ask on our forum or on StackOverflow. Please don’t use the blog comments below to report bugs.
