Major new features in RSF 0.6.4:

All-new validation framework based on BeanGuards(TM) - guaranteed execution of code packaged either as POJOs or Spring Validators, targetted at particular EL paths.

BeanScopes allow "long bean lifetimes" (e.g. within session scope) that, unlike flows are not tied to particular request sequences.

TargetListAggregatingBean framework enables multiple independent sources to target the same bean, enabling apps to built up out of truly modular components, each contributing their own core RSF definitions (e.g. request addressible beans, fetch bracketers &c)
[list]Integration with SpringMVC allows RSF's renderer (IKAT) to appear as a SpringMVC view technology alongside JSPs, Velocity &c.
[/list]

See the RSF Roadmap page for full release details.

All info available on the RSF wiki, discussion and support on the RSF forums (here!)
This will be the final 0.6.x release of RSF, work now begins on RSF 0.7 and the long-awaited feature of multi-file templating.
