JavaScript框架，jQuery 1.7.2 RC1 发布

     <p>jQuery 发布了 1.7.2 的首个 RC 版本，下载地址：<a href="/misc/goto?guid=4958332323803066886" target="_blank">http://code.jquery.com/jquery-1.7.2rc1.js</a></p>    <p>目前 jQuery 内部测试发现该版本跟当前 jQuery UI 以及 jQuery Mobile 1.1 RC1 有一个兼容性问题，这个问题将在下个版本中解决。</p>    <p>另外 jQuery 团队目前在 IE6 的支持方面碰到了一些麻烦，他们在 IE6 做单元测试的时候碰到各种零星的小问题，目前还无法确定这些问题的原因，最令人恼火的是这些问题并不总是出现，所以如果大家在使用过程中有发现相关跟 IE6 的问题并能找到原因请与 jQuery 开发团队联系。</p>
