----
1) ISSUE970:  Support for digitization in ddsim
                       ==> 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) ISSUE1173:  memory issue for large geometries
9)ISSUE1180: NEW: Relative include of files inside <plugins> starts from wrong directory
10)ISSUE1182: NEW Can not find Python_INCLUDE_DIRS $ Python_LIBARIES 
                       ==> Likely installation issue of ROOT
11) PR1016:    OpticalSurface example: fix detector driver
                       ==> Pending since November
12) PR1148:        RE-OPENED:  feat: convert several DDRec constructors to use const Detector&
13) PR1172: DetectorChecksum.cpp: fix a typo Problem: existing checksums get invalid!
14) PR1174: Kill photons as soon they enter into a OpticalTracker [Alvaro](verification ongoing)

2)    Closed issues and fixed problems
----
PR1176: G4VTouchable: for Geant4 11.1.ref09 cannot forward declare the class anymore
                Let's hope CMS is happy! We will tag it well before christmas
PR1175, ISSUE1166: Allow to load CAD files with relative path w/r to declaring xml file
PR1179, ISSUE1177: DDSim argument gun.energy is actually the total energy, not kinetic energy (fix comment text)
PR1181, ISSUE1180 Allow for XML processing of files relative to xml tag location
ISSUE1178:  NEW: Are 'surfaces' used by ddsim?
                      ==> Actually misleading: need to comment out certain plugins from the compact xml.
                              SurfaceManager, VolumeManager etc.

3) Round table
----
Markus:       EIC: Any interest in DDDigi ?
Andre:         NTR
Sunnanda:  Validating next G4 release. Otherwise ready for DD4hep for phase 2.
