0025     + binmake.gmk: moved definition of TARGOBJEXT to place not dependent
0026       on G4EXLIB, such that the extension is defined when no lib is present

0052         posting #155.
0053       o Moved renormalization of spin from G4EqEMFieldWithSpin and
0054         G4Mag_SpinEqRhs to G4ClassicalRK4 and G4SimpleHeum.
0055       o Added Spin propagation errors to the criteria for 'OneGoodStep' in

0066         normal for optical photons in rotated solids.
0067         Addresses problem report #1059.
0068       o Fix in G4PathFinder: a geometry is at a boundary if its step is within
0069         tolerance of the minimum step for any defined geometry.
0070       o Enhancement to the 'FB_intersects' algorithm in order to speedup Brent

0080       o Introduced to DistanceToIn(p,v) splitting of the distance for point
0081         very far from intersection area and big difference between solid
0082         dimensions and distance to it; resolves issue observed on 64 bits
0083         systems. Affected solids: G4Tubs, G4Cons, G4Sphere, G4Orb.
0084         Addresses problem report #1022.

0087         - Fixes in Inside(p) and in DistanceToIn(p,v) for points
0088           located on the curved surface within tolerance. Final fix for issue
0089           reported in problem report #1050 and concerning warnings reported by
0090           grid_test.
0091         - Introduced to DistanceToIn(p,v) splitting of the distance for
0092           point very far from intersection area and big difference between
0093           solid dimensions and distance to it; resolves issue observed on

0101       o Corrected typo in base implementation of GetSurfaceArea() in
0102         G4VCSGfaceted, which was erroneously returning cubic volume estimation.
0103         Addresses problem report #1062.
0104       o Relaxed error in G4TessellatedSolid::Inside(p) to warning,
0105         for excess of max trials and anomalous conditions in distance
0106         calculation. Added more printout information when error condition is
0107         detected.
0108     + volumes:
0109       o Get rid of unnecessary call to Reset() in G4NavigationHistory
0110         destructor.
0111       o Some code formatting.
0112 
0113   o Global:
0114     ------
0115     + Some improvements to G4String and G4SubString implementation of
0116       operators and comparison stub functions, to reduce generation of
0117       temporaries. Removed obsolete static hash(s) method in G4String.
0118     + Changed date for patch-02 to release 9.2.
0119 
0120   o Particles:
0121     ---------
0122     + Ascertain that the absolute of the argument to boost is <1.0

0124 
0125   o Standard Electromagnetic Processes:
0126     ----------------------------------
0127     + Muons: added protection against numerical problem due to negative
0128       value of transfered energy in G4MuPairProductionModel.

0133       o G4IonsKoxCrossSection, G4IonsShenCrossSection, G4TripathiCrossSection,
0134         G4TripathiLightCrossSection: added protections against numerical
0135         exceptions. Added simple check that cross-section is positive and
0136         removed not optimal control in G4TripathiLightIonCrossSection class.
0137         Added default constructor and destructor to G4TripathiCrossSection.
0138       o G4GGNuclNuclCrossSection: updated Glauber-Gribov cross section for ions.

0143     + models/parton_string:
0144       o Fix in G4SPBaryon for anti-baryon: a diquark & quark was given instead
0145         of anti-diquark & antiquark; note the reverse order, too.
0146         Fixes problems with incident anti-baryons, e.g. anti-proton,
0147         manifesting in problems with forming hadrons.
0148       o Changed pt sampling in G4LundStringFragmentation to avoid near endless
0149         loop; this should improve overall performance slightly.
0150         Addresses problem report #1066. Affected G4VLongitudinalStringDecay,
0151         where SampleQuarkPt() is implemented; added new optional argument of
0152         max Pt to SampleQuarkPt().
0153       o Modifications in G4GammaParticipants and G4QGSParticipants for
0154         applying QGSC from zero energy.
0155     + models/qmd:
0156       o Fixed bug in gamma (mass zero) participants in G4QMDCollision.
0157       o Changed object data member to pointer in G4QMDReaction.
0158     + models/rpg:
0159       o Removed global variables (pointers to static particle definitions) in
0160         G4RPGInelastic and replaced with local array. Fixing issues of wrong
0161         order for static initialization.
0162     + processes:
0163       o Fix to address problem report #1056: cross section data set now are
0164         created dynamically in G4PhotoNuclearProcess, G4ElectronNuclearProcess
0165         and G4PositronNuclearProcess.
0166       o Moved inline constructor and destructors to source in class
0167         G4PositronNuclearProcess.
0168 
0169   o Generic Processes:
0170     -----------------
0171     + Cuts:
0172       o Added missing implementation of GetParticleType() in
0173         G4VRangeToEnergyConverter.
0174       o Replaced usage of std::abs() with std::fabs() where appropriate.
0175     + Optical:
0176       o Fix in G4OpBoundaryProcess for complex index of refraction: resample
0177         the reflectivity every time for DielectricMetal, and do not re-calculate
0178         normal to facet; also fixed possible infinite loop by resetting iTE and
0179         iTM inside GetReflectivity().
0180       o Added exception for cases where invalid normal is returned;
0181         following problem report #1060.
0182 
0183   o Persistency:
0184     -----------
0185     + gdml:
0186       o Defined missing copy constructor and operator=() to G4GDMLMatrix
0187         internal class, to avoid cases of memory corruption when handling
0188         matrices.
0189       o Correction in materials and solids tags for allowing parsing of
0190         definitions within the tag scope; possibility foreseen by the schema.
0191       o Correction in G4GDMLWriteSolids::BooleanWrite() in order to handle
0192         cases of nested displaced solids given to both operands in a Boolean
0193         operation (ATLAS use case).
0194       o Renamed flag for maximum number of transformations applied to a solid
0195         and moved to G4GDMLWriteSolids base class.
0196       o First virtual layer for custom writer classes; added empty default
0197         constructor and virtual destructor to classes in new inheritance chain.
0198       o Restricted usage of loops only for placement of volumes. Now correctly
0199         handling most common use-case of multiple copies of the same
0200         volume/solid through loop statement. Addressing problem report #1063.
0201 
0202   o Physics Lists:
0203     -------------
0204     + Fix to address problem report #1056: all cross section data sets are
0205       created dynamically and no longer member of the class.
0206       Fix in G4HadronInelasticQBBC: cross sections are created dynamically
0207       not by value, fission only instantiated for HP.
0208     + Inline constructor and destructors are moved to source for classes:
0209       G4VNeutronBuilder, G4VPiKBuilder, G4VProtonBuilder, G4WarnPLStatus.
0210 
0211   o Visualization:
0212     -------------
0213     + HepRep: added inclusion of <cstdio> in DeflateOutputStreamBuffer
0214       header to resolve compilation errors reported by gcc-4.4.0.
0215 
0216   o Examples:
0217     --------
0218     + Removed unnecessary AIDA setup in GNUmakefiles wherever necessary.
0219     + advanced/air_shower:
0220       o Updated README file.
0221     + advanced/nanobeam:
0222       o Fixed compilation warnings on gcc-4.3 on SLC5.
0223     + advanced/radiation_monitor:
0224       o Added macros reproducing run results: new results with proton at
0225         254MeV, 150 Mev and 50 Mev of energy; new macros with Kapton material.
0226       o Changed limits of LENeutronInelastic for 0.1 GeV in
0227         RadmonPhysicsNeutronBertini and RadmonPhysicsNeutronBinary classes.
0228       o Fix for compilation error in RadmonTLabelledCollection.
0229     + advanced/xray_fluorescence:
0230       o Reviewed physics setup and analysis.
0231     + extended/analysis/AnaEx01:
0232       o Corrected GNUmakefile and some cleanup.
0233     + extended/field/field04:
0234       o Commented out timing on initial seed for reproducibility of results.
0235     + extended/persistency/gdml/G01:
0236       o Modified loop.gdml to restrict multiple placements within a loop.
