1) Pending problems

1.1) Pending problems reported by Sang Hyun Ko:
     - Cannot setup Birk's constant as material property.
     - No analogy to G4PVParametrized. Unclear if a solution is possible.
1.2) Add GFlash parameterisation to DDG4 (issue #802)
1.3) Problems with ROOT-python compatibilities (issue 842)
       ==> Waiting for Paul to provide a PR
1.4) DDG4: isotropic gun distribution also forces uniform momentum distribution #862
       ==> Waiting for Wouter to provide PR
1.5) std::terminate handling and Geant4 (CMS request)

       ==> Assigned to Markus
1.6) DD4POD: Waiting for PR from Whitney

1.7) Geant4 11.0 beta open issues between snapshot compilation
1.8  PluginFactoryBase::make_return problem with longs (Issue 875)

2)    Closed issues and fixed problems
----

3) Round table

3.1  Wouter:      DDG4 particle handler has SEGV. Problematic are "stable" particles which decay
       and are  given to Geant4. These are double-deleted and cause problems. The solution is to add
       these to the rejection list so that they are excluded from Geant4 processing.
3.2  Carl:          NTR
3.2  Andre:       some plugin problems still to be understood.
3.3  Sylvester:  NTR
3.4  Frank:       Interest in GFlash

4) AOB
