1) Pending problems

----
1) ISSUE970:  Support for digitization in ddsim
                       ==> On hold, but should be closed.
2) ISSUE1103: Allow isotrope generator to throw range around specified (reference) direction: Waiting for user
3) ISSUE1163: materialScan is not adapted for USE_GEANT4_UNITS
4) ISSUE1167: Charge sharing across tracker segmentation  ---> DDDigi
5) ISSUE1173:  memory issue for large geometries
                       ===> Discussion ongoing, but is not really an issue. Geometries have to be build not with brute force.
NEW:
7)  ISSUE1200: Using rotation in DDCAD to rotate around z axis 
                      ===> Should be a non-issue (?)
8)  ISSUE1199:Persist hepmc vertex status code into output
                     ===> Should we eliminate Geant4EventReaderHepMC
                     ===> Decision: Geant4EventReaderHepMC will be removed
9)   ISSUE1197:  DDEve cannot be built against ROOT without webgui
10) ISSUE1193:  Custom identifiers for readouts are not (no longer) working
                     ===> Actually lc_geo issue. Issue in the CaloPrototype code.
11) ISSUE 1194: DD4hep incompatible with Python 3.12 
       PR1195 Replace imp module usage
12) PR1198 Set the edm4hep::MCParticle momentum as doubles once it becomes possible

2)    Closed issues and fixed problems
----
1) PR1191 Add a check for the standard that Geant4 was compiled with
     ISSUE  1143: cmake: CMAKE_CXX_STANDARD overruled by Geant4_CXX_FLAGS in DDG4
                 (Juan Miguel Carceller/CERN)
2)  PR1196: Use std::abs, ddsim logging of sensitive detectors
      PR1192 DetectorChecksum: use fabs for checking null
      ISSUE 1188: Platform discrepancy in Detector checksum computation  (Andre)
3) PR1187
     ISSUE 1186: Seeing deeper hierarchy in teveDisplay (Markus)
4) ISSUE1117:  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
     === Assumed fixed with latest ROOT. Closed due to no reaction.
5) ISSUE1183: Varying roughness of optical surface for reflection
                       ==> Non-issue. Requested stuff is present. Asked to close after verification.
                       ===> Closed due to no reaction
6) PR1201 Incorporate type fix from https://github.com/AIDASoft/DD4hep/pull/1172. Improve checksum debugging possibilities.
7) PR1172: DetectorChecksum.cpp: fix a typo. Will make existing checksums invalid.
8) PR1202 Typo fix in user's manual (Dmitry Kalinkin)
9) ISSUE1203: How to visualize the electric or magnetic fields in DD4hep
                     ===> Summer student project ?

3) Round table
