                       ==> On hold
2) ISSUE1103: Allow isotrope generator to throw range around specified (reference) direction: Waiting for user
3) ISSUE1117:  RE-OPENED: New visualization by reference edits alpha value of referenced VisAttr.
                       Apparently order of creating logical volumes affects visualization attributes
                       Changes in ROOT now present. Still requires update in DD4hep
                       See: PR1155
4) ISSUE1143: DetectorChecksum memory consumption scales with complexity (and maxes out...): Wait for user
5) ISSUE1163: materialScan is not adapted for USE_GEANT4_UNITS
6) ISSUE1168: Allow to give CAD files with relative paths similar to importing xml files (DDCAD)
7) ISSUE1167: Charge sharing across tracker segmentation  ---> DDDigi
8) PR1016:    OpticalSurface example: fix detector driver
                       ==> Pending since November
9) PR1172:   DetectorChecksum.cpp: fix a typo Problem: existing checksums get invalid!
10) PR1148: feat: convert several DDRec constructors to use const Detector& (work in progress)
