## 2025-08-14 Alberto Ribon (hadr-string-diff-V11-03-00)
- G4FTFModel, G4DiffractiveExcitation : introduced the classification of
quasi-elastic and diffractive interactions among the inelastic interactions
of the FTF string model.
In the G4FTFModel class, the boolean flags fIsQuasiElasticInteraction and
fIsDiffractiveInteraction - inherited from the base class
G4VHighEnergyGenerator - are used in the methods Init and ExciteParticipants.
In the class G4DiffractiveExcitation, an extra, boolean parameter is added
to the method ExciteParticipants to tag diffractive interactions.
## 2024-07-18 Alberto Ribon (hadr-string-diff-V11-02-00)
- G4FTFParameters : renamed method SetElastis as SetElastic.
This does not have any effect - the random sequence stays the same.
