jQuery 1.6 RC 1 Released

This is a preview release of jQuery. We’re releasing it so that everyone can start testing the code in their applications, making sure that there are no major problems.

You can get the code from the jQuery CDN:

• http://code.jquery.com/jquery-1.6rc1.js

You can help us by dropping that code into your existing application and letting us know that if anything no longer works. Please file a bug and be sure to mention that you’re testing against jQuery 1.6 RC 1.

We want to encourage everyone from the community to try and get involved in contributing back to jQuery core. We’ve set up a full page of information dedicated towards becoming more involved with the team. The team is here and ready to help you help us!
