## 1.3. Restrictions

Orchestra comes out with an innovative architecture based on a generic and extensible engine, called "The Process Virtual Machine" and a powerful injection technology allowing services pluggability.

This new version of Orchestra is aimed at showing the power of its very innovative architecture by providing support for all the basic activities defined in the BPEL standard. As stated in the previous section, this version provides the possibility to persist the processes definition and execution. The 4.2 release provides support for the last important BPEL statement named eventHandler. Orchestra now provides full support of BPEL 2.0. The next stage will be to extend Orchestra to provide the first Open Source Business Process Server to power your SOA infrastructure. Stay tuned ! Check the roadmap for more information.
