Dojo1.4终于发布了，该版本在性能和稳定性上都较上一版本有着明显的提升。功能上当然也新增了不少，主要包括如下一些内容：
IO Pipeline topics
dojo.cache
dojo.contentHandlers
dojo.hash with native HTML5 onhashchange event support where available
Traversal and manipulation for NodeLists (the return value for dojo.query)
dojo.ready (easier to type than dojo.addOnLoad)
Hundreds of refinements to the Dijit API and collection of Dijits, and a few new widgets in DojoX
DataChart widget and other improvements to charting
dojox.drawing lands!
Editor improvements and new plug-ins in both Dijit and DojoX
Grid is faster, and the EnhancedGrid lands!
ForestStoreModel for the TreeGrid
GFX improvements
dojox.jq, a very experimental module aimed at trying to match the jQuery API as close as possible, but using Dojo underneath
