dojo 1.2 已经延迟了3个礼拜，但是经过对1.2Nightly builds的测试，性能的确有很大的提升，尤其是Grid，无论在处理内存方面还是细节方面都比原来有了很大的改进

下面是Dojo1.2的描述：

API-compatible with Dojo 1.0 and 1.1,Dojo 1.2 will feature:

• major improvements to the visual polish of the Dijit component set
• refactoring of the Grid component to remove cruft,add new features,and improve integration with dojo.data
• updates to charting to support tooltips,animations,and events plus new chart types
• continued work to improve the speed,stability,and compatibility of the Core
