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)ISSUE1182: NEW Can not find Python_INCLUDE_DIRS $ Python_LIBARIES 
                       ==> Likely installation issue of ROOT
10) PR1148:        RE-OPENED:  feat: convert several DDRec constructors to use const Detector&
11) PR1172: DetectorChecksum.cpp: fix a typo Problem: existing checksums get invalid!

NEW:
12) ISSUE1185: cmake: CMAKE_CXX_STANDARD overruled by Geant4_CXX_FLAGS in DDG4 #1185
13) ISSUE1183: Varying roughness of optical surface for reflection
                       ==> Non-issue. Requested stuff is present. Asked to close after verification.

Andre:        new DD4hep tag 1.27.0.
Thomas:     NTR
 

4) AOB

Thomas: Are there hooks to flag SimCalorimeterHit objects after fast simulation.
                 Not yet, but should be simple to implement.
