Spring Web Flow 2.0
The first milestone release of Spring Web Flow 2.0 has been released.
We are pleased to announce that the first milestone of the next generation version of Spring Web Flow is now available. Spring Web Flow 2.0 M1 introduces several major new features, including support for flow-managed persistence contexts, improved support for Java Server Faces, full unified expression language (EL) support, and a more comprehensive sample web application.
I think the most interesting part of this release is Spring Faces:
Spring Web Flow 2.0 M1 introduces the Spring Faces module (spring-faces-2.0-m1.jar), a component shipped with the Web Flow distribution that contains first-class support for organizations developing web applications with Java Server Faces. The pre-existing Web Flow + JSF integration has been factored out to this project, and this project will be the home of all future JSF integration work.
The Spring Faces module provides the Spring community a dedicated project for exploring additional JSF integration opportunities. The initial work in 2.0 M1 on this front introduces integration with Ext, a popular Javascript GUI widget framework.
Of course, I also like how the new sample app looks a lot like one of Seam's demos. 
JSF has needed a good client-side validation framework for quite some time. I also like the Ext integration as most JSF date pickers are hideous. Well done gents.
