The jQuery team has been working hard on the new release of the jQuery library and it’s ready for some in-depth testing! jQuery 1.3 is not ready for production use yet but we need help to weed out any bugs that might’ve snuck through.
看上去jQuery团队们都很辛苦，所以，小白鼠们，你们也辛苦一点，把BUG测试的多一点，我们在以后的项目中才敢正常的应用啊。
自己也是用jQuery的，应该也会测试一些，特别是针对这次更新的功能：
- Selector Engine - The selector code has undergone a complete rewrite - it’s likely that some edge cases still exist here.
- DOM Manipulation (append/prepend/before/after) - This code has also undergone a large rewrite along with some of the logic for executing inline script elements.
- .offset() - Another method that has been completely rewritten.
- Event Namespaces - The logic for handling namespaced events has been completely rewritten.
- Event Triggering - When triggering an event the event now bubbles up the DOM - this is likely to cause some problems.
选择器改写，DOM控制器又是大的改写，.offset改写,事件命名空间改写，不知道改写后效率会怎么样，当然，估计改写也应该是冲着效率而去的，否则改写的意义也不是特别大了。
事件触发，针对DOM的事件触发？估计问题也会挺多，他们也是这么认为的。DOM太难控制了，毕竟不是每个页面都是按照规范来写的。
如果你写了一些代码，并认为它触发了这些BUG，你可以提交到：http://dev.jquery.com/ ，当然提交的代码尽量是简短一些，提交的时候也需要将你的mail写上，这样，jQuery Team可能在修改后会通知你的哦。
