请问
jQuery 1.1.3.1在原来的基础上都做了那些修改
对我原来的程序有什么影响
又有哪些新的功能呢？

也不知道是没有找到呢还是官方站点没有提到

• Improved speeds, with DOM traversal over 800% faster than in 1.1.2
• A re-written event system, with more graceful handling of keyboard events
• A re-written effects system (with an accompanying fx test suite), featuring faster execution and better cross-platform support
• New selectors: Unicode, Escape, Inequality, and more
• Animation Improvements: You can run more simultaneous animations without incurring any speed hits
• $(”div”).is(”:visible, :first”)
• jQuery.browser.version

刚才看到新版本和老版本的相比，增加的一些功能
