Prototype 1.6.1 RC2

第一个接触的JS lib，现在转向jQuery，用得比较少了。这个版本主要是对 Internet Explorer 8 进行了一些兼容方面的优化。

更新如下：

Full compatibility with Internet Explorer 8. Juriy has spearheaded the effort to replace most of our IE “sniffs” into outright capability checks — making it far easier to support IE8 in both “super-standards” mode and compatibility mode.
Element storage, a feature announced previously. Safely associate complex metadata with individual elements.
mouseenter and mouseleave events — simulating the IE-proprietary events that tend to be far more useful than mouseover and mouseout.
An Element#clone method for cloning DOM nodes in a way that lets you perform “cleanup” on the new copies.

一些改进：

Better housekeeping on event handlers in order to prevent memory leaks.
Better performance in Function#bind, Element#down, and a number of other often-used methods.
A number of bug fixes.
