jQuery 1.7.2 Beta 1 Released

Posted on by

Hey there Internets, it’s the jQuery Core team! We haven’t talked in a while, but over the holidays we were busy fixing the bugs you reported. The result of that hard work is jQuery 1.7.2 Beta 1. We decided to get a beta out by Groundhog Day so you wouldn’t be in the shadow of six more weeks of unfixed bugs.

You can get the code from the jQuery CDN:

Oh, we know what you’re thinking: “Cool, a new version of jQuery; I’ll wait until the final release has been out a few weeks and then I’ll give it a try.” Right, and then you’ll find some bug that keeps you from upgrading. Nothing makes us sadder than finishing up a release and only then seeing a report of a serious bug that could have been fixed earlier.

So please, come out of your burrow and try this beta with your code. Did we miss an old bug? Did we create a new bug that makes you feel like Bill Murray waking up to “I Got You Babe?” We want to know. 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.
