We exposed the attributes we have added with the Modeler release 2.6.1 on the properties panel, namely i/o mapping, connectors and asyncBefore/asyncAfter.
Two new tabs were added to the properties panel in order to configure Input/Output parameter and connector settings. A new input dialog was implemented for adding and editing the parameter details.
