There are some minor issues with the latest servant commit: 1) in https://gitlab.eclipse.org/eclipse/simopenpass/simopenpass/-/blob/servant/sim/contrib/examples/PCM_Re-Simulation/opSimulationManager.xml it should say "<libraries>modules</libraries>" 2) the version in GUI is still v0.7 3) there are at least two old config files named "masterConfig.xml", which are not used anymore Please, fix the issues on servant via a bug-fix branch and merge again to master. I will move the official tag v0.8 then...
