| 101 | + come from internal conversion. |
| 102 | + + cascade: |
| 103 | + o G4CascadeCheckBalance: fixed outstanding problem of the interface with |
| 104 | + native pre-compound model, happening when in the default de-excitation |
| 105 | + internal electron conversion gets enabled. |
| 106 | + o G4CascadeInterface: fixed memory leak by deleting ltcollider in class |
| 107 | + destructor. |
| 108 | + o G4CascadeParamMessenger.cc: ensure that Bertini-specific commands get |

| 124 | + memory leak. Addressing problem report #2164. |
| 125 | + o G4RadioactiveDecay, G4RadioactiveDecayBase: changed default verbosity |
| 126 | + from 0 to 1, and remove G4cerr wherever it occurs and replace it with |
| 127 | + G4Exception or G4cout. |
| 128 | + Increased verbosity thresholds in order to reduce printout size. |
| 129 | + o G4BetaPlusDecay: changed sign of daughterZ argument in |
| 130 | + G4BetaDecayCorrections according to problem report #2199. |
| 131 | + o Fixed Coverity warnings in G4RadioactiveDecay and |

| 144 | + include_directories are now explicitly removed. |
| 145 | + Addressing problem report #2215 |
| 146 | + |
| 147 | + o Data sets: |

| 153 | + o Examples: |
| 154 | + -------- |
| 155 | + + basic |
| 156 | + o Fixed comment for suggested command "/run/numberOfThreads" in macros. |
