0006
0007 List of fixes included in this public patch since the public release 10.2.p02:
0008
0009 o Configuration:
0010 -------------
0011 + CMake:
0012 o Correctly export USolids/VecGeom settings to GNUmake configuration
0013 scripts.

0021
0022 o Error-Propagation
0023 -----------------
0024 + G4ErrorPhysicsList: replaced direct use of 'aParticleIterator' with
0025 GetParticleIterator(), to allow for porting on clang-3.9 and XCode-8
0026 on MacOS.
0027
0028 o Event:
0029 -----
0030 + Fixed way of deleting G4PrimaryVertex objects to avoid stack overflow
0031 for very large number of primary vertices.

0039 + management:
0040 o Moved initialisation of G4GeomSplitter thread-local data to be inline
0041 along with generic template type; moved accessors/modifiers for splitter
0042 data to non-inline in G4Region, G4LogicalVolume and G4VPhysicalVolume.

0049 o G4ReplicaNavigation: use Cartesian tolerance in distance evaluation
0050 in DistanceToOutPhi(). Addressing problem report #1902.

0077 G4GenericPolycone. Fixed minor typos in G4GenericTrap::SurfaceNormal()
0078 and G4VTwistSurface::CurrentStatus::ResetfDone().
0079 Addressing problem report #1876.
0080 o Use G4RandFlat instead of RandFlat.
0081 + volumes:
0082 o Correction in G4NavigationHistory default constructor to use
0083 GetLevels() instead of GetNewLevels() from G4NavigationHistoryPool,
0084 to favor re-use of already allocated space.

0096 along with generic template type. Fixing compilation/linking errors on
0097 clang-3.9 and XCode-8 on MacOS.
