[rules-users] [Drools Flow 5.1] Updating a process definition -> Proceed updates running processes

[Salaboy]

Well the documentation sounds clear to me. The running process instances will continue running with the old version of the process and the new ones will pick the last uploaded version. If someone modifies the process definition a new version of the process will be created.
