今天RichFaces 4.0.0正式版发布了! Richfaces 4 Ajax 支持使用JQuery进行了重写，支持客户端验证，重新设计了Push支持。
RichFaces是一个基于LGPL协议开源的JSF(JavaServer Faces)组件库，它是使应用开发能够方便地集成AJAX处理能力的先进框架。RichFaces库由Ajax4jsf和RichFaces两部分组成。
该版本新改进：
- Minor, low risk stabilizations, and clean up tasks for the Final build to minimize risk.
- Thorough review of all the component attributes done and corrections were made based on complexity.
- Bug fixing for CSV and Object Validation features.
- Refactored Listeners classes, methods and Event names according to standard JSF convention.
