Bossa is a workflow engine written in Java. The engine is very fast and lightweight, uses a very expressive Petri net notation to define workflows, does not require a RDBMS, and is very simple to use and integrate with Java applications. Actually, it was designed to be embedded. Therefore, Bossa is organized as a library to be used by server-side applications (especially Web-oriented ones) that need workflow services.
XML importing of case types has been added. It is possible to use the PNK as a graphical case type editor. New administrative functions were added, including the much requested explicit create/close case. A couple of bugs were fixed.
