                      ---------------------
This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.
It DOES NOT substitute the  CVS log-message one should put at every
committal in the CVS repository !

26 October 10: V.Ivanchenko (emhighenergy-V09-03-02)
- Fixed problem reported by the Coverity tools (mainly pedantic 
  initialisation)
- Added G4mplIonisationWithDeltaModel which is substituted
  G4mplIonisationModel by default - delat-ray production is required
  both by ATLAS and CMS

- G4mplIonisation - fixed IsApplicable method - always "true" 
                    (CMS report crash in the case when several types 
                     of monopoles are instantiated)

- Updated processes enumeration and printout

21 July 08:  V.Ivanchenko (emhighenergy-V09-01-05)
- G4hBremsstrahlungModel, G4hPairProductionModel - do not use A in
                          the CrossSectionPerAtom

10 July 08:  V.Ivanchenko (emhighenergy-V09-01-04)
- G4eeCrossSections - migrated to PDG 2006
- G4eeToHadronsMultiModel - added main reaction channels for omega and 
                            phi resonances
- New models: G4eeTo3PiModel, G4eeToPGammaModel, G4ee2KChargedModel, 
  G4ee2KNeutralModel

  void, extra parameter std::vector<G4DynamicParticle*>*, all
  classes using or inhereting this interface are modified.
