1) Pending problems

----

1) DDDigi TBB code needs migration to new oneAPI TBB interfaces (Issue 901):
      Clash between Intel oneapi TBB and classic TBB.
      -- Wouter promised to look into.
2) Issue 940: Integration of external library (CRY) for cosmic ray generation in DDG4 simulation: on hold
3) Issue 970: Support for digitization in ddsim: on hold
4) Issue 984: DD4hep output with MarlinDD4hep
5) Issue 985: dummy material exported into gdml is not recognized by Geant4 (Markus)

                        ===> Fix developed in the TGeo GDML writer - not yet submitted
                        ===> Related: Issue 1014: TGeo GDML description needs fixing for surfaces (Markus)

6) Issue 988: Propagate cross section to the simulation (on hold)
                        ===> likely a EDM4hep problem
7) Issue 1014: Issue using optical surfaces
                        ===> Related: Issue 1027 (Program never stops)

8) Issue 1020: Calorimeter Energy Deposition with Multiple Readout Segmentations
       Energy deposit depends on segmentation (not confirmed by Andre)
 

2)    Closed issues and fixed problems
----

1) PR 989:     Automatically interpret hepmc3 input files (W. Deconinck)
2) PR 1017:  Fix for HepMC vertex issue (Andre, Kauder)
3) Issue 994: Geometry checksum/hash for consistency checks between simulation and reconstruction steps
                      ===> PR 1021 (Markus)
4) Issue 1010:  Changing Geant4 physics flags

                      ===> PR 1021 (Markus)
4) PR1016: Fix to optical surface example detector driver (Andre) (not merged)
