Prototype 日前发布了 Prototype 1.6.1 RC2 版本，该版本主要修正了与 IE8 的兼容性问题以及元素存储和补丁修正。
- 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.
mouseleaveevents — simulating the IE-proprietary events that tend to be far more useful than
Element#clonemethod for cloning DOM nodes in a way that lets you perform “cleanup” on the new copies.
- Better housekeeping on event handlers in order to prevent memory leaks.
- Better performance in
Element#down, and a number of other often-used methods.
- A number of bug fixes.
