0107 o Fix in G4DNAMolecularMaterial to prevent segmentation fault in case a
0108 model is not created at initialisation time.
0109 + Low Energy:
0110 o Suppressed exception warning issued by some Penelope models;
0111 Controlled by verbosity flag now for diagnostics.

0114 is inkoved in a unit test.
0115 o Fixed Coverity report in G4LivermorePhotoElectricModel.
0116 + Standard:
0117 o Bug fix in G4UrbanMscModel; 1st normal step in StepLimitType 2 mode

0124 Reduced number of divisions by addition of extra class members.
0125 o G4NuclearStopping: fix to avoid changing ion charge.
0126 o G4ionIonisation: do not instantiate extra model at high enegry if
0127 G4IonParameterisedModel is used. Improved printout at initialisation.
0128 o G4SauterGavrilaAngularDistribution: use Penelope 2008 sampling
0129 algorithm, as it is more effective; distribution itself is unchanged.

0131 and G4Exp().
0132 o G4eCoulombScatteringModel, G4eSingleCoulombScatteringModel: get pointer
0133 to the vector of cuts from parameters of Initialise(..) method and not
0134 from G4ProductionCutsTable; more convenient for unit tests.

0144 in one job (affecting muons and e- and providing non-reproducibility)
0145 o G4LossTableMananger, G4EmProcessOptions: define default verbosity=0
0146 for worker thread, so summary on EM processes is not duplicated.

0180 o G4BinaryLightIonReaction: fix for Coverity report on small leak.
0181 o Added printout of particle name in check for valid type of projectile
0182 in G4BinaryCasacde::ApplyYourself().
0183 + models/de_excitation:
0184 o G4ExcitationHandler: fixed minor memory leak in the case when
0185 FermiBreakUp has no final states available; reported in item
0186 #1371 in hypernews Hadronic forum.
