jQuery 1.7 Beta 2 Released

Hot off the momentum of the jQuery Conference in Boston earlier this month, and based on the community’s valuable feedback, we’re releasing a new beta that incorporates further fixes and improves stability. The full list of fixes and features can be found below. We urge everyone to start testing this code in their applications, so we can make sure that there are no major problems before the final release.

You can get the code from the jQuery CDN:

• http://code.jquery.com/jquery-1.7b2.js

Please help us by dropping that code into your existing application. If you see something, say something. File a bug and mention that you’re testing against jQuery 1.7 Beta 2. If there’s a problem we want to fix it!
