| 8 | + |
| 9 | + o Configuration: |
| 10 | + ------------- |
| 11 | + + CMake: |
| 12 | + o Fixed bug in checking of status of Xmu include path and library |

| 44 | + extruded-solid) for wrong computation of DistanceToIn(p,v) for |
| 45 | + points outside, when optimisation is active. |
| 46 | + o Fix in G4TessellatedSolid::DistanceToIn(p,v) for specific cases |
| 47 | + where points are located near surface. |

| 49 | + the two extremes of the segment. Addressing problem report #1541. |
| 50 | + |
| 51 | + o Global: |
| 52 | + ------ |
| 53 | + + Updated date and version for 9.6.p03. |

| 66 | + o G4NuclearStopping: do not reset dynamic charge of an ion, because |
| 67 | + G4ionIonisation process is responsible for that (fix for partially |
| 68 | + charged ion beam) |
| 69 | + + Utils: |
| 70 | + o G4VMultipleScattering: increased lowest limit from 1 eV to 10 eV to |
| 71 | + avoid semi-infinite loop for low-energy particle tracking; |
| 72 | + fixed re-computation of post-step safety in AlongStepDoIt method. |
| 73 | + o G4VEnergyLossProcess, G4VEmProcess: set interaction length to |

| 76 | + o Fixed typo in G4EmBiasingManager. |
| 77 | + |
| 78 | + o Generic Processes: |

| 89 | + + models/cascade: |
| 90 | + o G4NucleiModel: fixed rare cases of non-reproducibility in |

| 92 | + initialized in the case that the interaction-partners list has |
| 93 | + one single element. |
| 94 | + o Fixed implementation of G4CascadeParameters singleton to follow |
| 95 | + canonical format. Addressing problem report #1557. |
| 96 | + o G4ParticleLargerEkin, G4ParticleLargerBeta: correct ">=" to ">" |
| 97 | + conditions to avoid error in case that both inputs are identical. |
| 98 | + + models/de_excitation: |
| 99 | + o G4NeutronRadCapture: fixed run time memory leak, fixed time of |
| 100 | + reaction products. |
| 101 | + o G4ExcitationHandler: if FermiBreakUp returns unchanged fragment |
| 102 | + delete it to avoid minor memory leak; addressing HyperNews post |
| 103 | + #1371. Fixed typo in GetPhotoEvaporation() method name. |
| 104 | + Fixed typo in the SetMaxAForFermiBreakUp() method. |
| 105 | + o G4FermiFragmentsPool: fixed typo for use of G4endl for end line. |

| 107 | + detected on Visual C++ 18. |
| 108 | + + models/em_dissociation: |
| 109 | + o Fixed memory leak of products from G4ExcitationHandler. |

| 111 | + o Fixed two mistakes in the index manipulation of the BaryonWeight |
| 112 | + 4-dimensional vector in G4LundStringFragmentation. |
| 113 | + + models/parton_string/management: |
| 114 | + o Fix to remove 'inline' qualifier from methods in G4VParticipants.cc |
| 115 | + and G4PomeronCrossSection.cc, responsible for cases of run-time |
| 116 | + errors for undefined symbols in library... |
| 117 | + + stopping: |
| 118 | + o G4MuMinusCapturePrecompound: fixed case of infinite loop by |
| 119 | + reimplementing old algorithm of mu- capture which does not include |
| 120 | + direct muon reaction but only considering de-excitation of residual |
| 121 | + fragment. Addressing problem report #1536. |
| 122 | + |
| 123 | + o Materials: |

| 136 | + Addressing problem report #1504. |
| 137 | + o Corrected typo in G4tgrUtils::WordIsUnit(). |
| 138 | + o Replaced deprecated calls to solids accessor methods. |
| 139 | + + gdml: |
| 140 | + o Fix in G4GDMLReadParamvol::ParametersRead() for reading parameterised |
| 141 | + Sphere, Orb, Torus and Para. |
| 142 | + o Replaced deprecated calls to G4Sphere accessor methods. |
| 143 | + |
| 144 | + o Physics Lists: |
| 145 | + ------------- |
| 146 | + + G4EmStandardPhysics_option3, G4EmStandardPhysics_option4, |
| 147 | + G4EmLivermorePhysics, G4EmPenelopePhysics: use RangeFactor=0.01 |
| 148 | + for increased simulation accuracy; use G4UrbanMscModel96. |
| 149 | + |
| 150 | + o Visualization: |
| 151 | + ------------- |
| 152 | + + OpenGL: |
| 153 | + o Fixed bug in the G4OpenGLQtViewer for viewer iterator increment |
