S4 0.5 (code named "piper") is a complete rewrite, grounding on previous 
work, aimed at facilitating development, and featuring for instance:
- eased configuration (type-safe, no XML)
- facilities to package applications
- reliable communication channels
- dynamic deployment of applications
- improved fault tolerance

This list is not exhaustive though and there is no fixed release date.

If you are already using S4 0.3, note that even though the platform will 
change substantially and won't be backward compatible, the concepts and 
driving ideas remain the same, therefore porting existing applications 
to that new version will be quite straightforward.
