23-Jun-2022 A. Ribon       hadr-partonstring-mgt-V10-07-04
- G4VSplitableHadron : changed the method Splitting() from "protected" to
  "public" (this is needed to change the status of SplitableHadron in
  G4FTFAnnihilation, to fix the non-isotropic angular distributions of
  secondaries in annihilations at rest).
  This change was made by Vladimir Uzhinsky.

09-Feb-2022 G. Cosmo       hadr-partonstring-mgt-V10-07-03
- Fixed compilation warning on Intel compilers for unused variable.

27-Oct-2021 A. Ribon       hadr-partonstring-mgt-V10-07-02
- G4VParticipants, G4VPartonStringModel : extended for projectile
  hypernuclei and anti-hypernuclei

16-Apr-2021 B. Morgan      hadr-partonstring-mgt-V10-07-01
- Migrate build to modular CMake API

13-Apr-2021 A. Ribon       hadr-partonstring-mgt-V10-07-00
- GNUmakefile, sources.cmake : removed the subdirectories
  hadronic/models/management and hadronic/models/util
  (that have been now deleted, with their classes moved to
   hadronic/util and hadronic/management).

29-Oct-2020 B. Morgan      hadr-partonstring-mgt-V10-06-03
-  Remove inclusion of obsolete CMake module

24-Jul-2020 A. Ribon       hadr-partonstring-mgt-V10-06-02
-  G4VPartonStringModel : introduced a new pre-processor option for
   debugging heavy hadrons, switched off by default.

08-Mar-2020 V. Ivanchenko  hadr-partonstring-mgt-V10-06-01
-  G4VParticipants, G4VPartonStringModel, G4VStringFragmentation,
   G4StringModel - clean-up: removed unused methods, delete
     operators, use C++11 keywords

24-Feb-2020 V. Ivanchenko  hadr-partonstring-mgt-V10-06-00
-  G4VStringFragmentation : use inheritance from G4HadronicInteraction;
     removed implementations of private operators.

28-Nov-2019 A. Ribon       hadr-partonstring-mgt-V10-05-02
-  G4VPartonStringModel : fixed bug (use of "=" instead of "==" in
   if-statement, found by Coverity) in the Scatter method.

19-Nov-2019 A. Ribon       hadr-partonstring-mgt-V10-05-01
-  G4EventGenerator, G4InteractionCode, G4VertexCode : deleted unused classes.

14-Nov-2019 A. Ribon       hadr-partonstring-mgt-V10-05-00
-  G4VPartonStringModel : re-sample the string formation in the case that
   the (either target or projectile) nuclear residual is an unphysical
   combination of nucleons (i.e. more than three protons with no neutron,
   or more than one neutron with no proton).

20-Nov-2018 A. Ribon       hadr-partonstring-mgt-V10-04-03
-  Minor clean-up: no changes in the random sequence.

05-Nov-2018 G. V. Uzhinsky      hadr-partonstring-mgt-V10-04-02
- If something is bad in QGSM, G4VPartonStringModel.cc will return initial
  particle/nucleus. See line 150:
  if(strings->size() == 0) {Success=false; continue;}
  FTF instead of vector "strings" returns 0! Thus, a corresponding changes
  are introduced in FTF.

19-Dec-2017 G. Cosmo      hadr-partonstring-mgt-V10-04-01
- Fixed self-consistency in G4VertexCode header (missing #include).

08-Nov-2017 A. Ribon      hadr-partonstring-mgt-V10-03-04
-  Minor clean-up and indentation: no changes in the random sequence.

26-Oct-2017 A. Ribon      hadr-partonstring-mgt-V10-03-03
-  Re-introduce temporarily G4PomeronCrossSection class needed by the stable,
   production version of QGS model.

19-Jan-2017 A. Ribon      hadr-partonstring-mgt-V10-03-02
-  Removed G4PomeronCrossSection class.

16-Dec-2016 A. Ribon      hadr-partonstring-mgt-V10-03-01
-  Temporary work-around to bring back only qgsm: in practice, re-introduce
   temporarily G4PomeronCrossSection class.

14-Dec-2016 A. Ribon      hadr-partonstring-mgt-V10-03-00
-  After the release G4 10.3, with "stable" version, this tag brings back
   the "development" version, similar (although not identical because
   of some code clean-up) to G4 10.2.ref10.

12-Oct-2016 V. Uzhinsky  : hadr-partonstring-mgt-V10-02-04
   G4Exception was introduced in G4VPartonStringModel which gives a warning
   message when parton model cannot produce or fragment strings. In the case
   projectile hadron and target nucleus will return unchanged to a caller.

28-Sept-2016 V. Uzhinsky : hadr-partonstring-mgt-V10-02-03
-  G4VPartonStringModel: Repetition is implemented of an event simulation
   if strings were not generated, or the hadronization could not manage
   with string's fragmentation. An exception is generated after 100 attempts.

19-Sept-2016 V. Uzhinsky : hadr-partonstring-mgt-V10-02-02
-  G4VPartonStringModel: G4HadronicException was implemented for the case
   when the string fragmentation does not produce hadrons!

29-June-2016 V. Uzhinsky : hadr-partonstring-mgt-V10-02-01
-  G4VPartonStringModel::Scatter was improved in order to protect
   a case when string's fragmentation does not give a result.

18-May-2016 A. Ribon      hadr-partonstring-mgt-V10-02-00
-  G4PomeronCrossSection : moved into the qgsm/ directory.

07-Aug-2015 A. Ribon      hadr-partonstring-mgt-V10-01-02
-  G4VPartonStringModel : checking of 'while' loops.

05-Aug-2015 A. Ribon      hadr-partonstring-mgt-V10-01-01
-  G4PomeronCrossSection : replaced std::exp, std::log and std::pow
   with the faster G4Exp, G4Log and G4Pow, respectively.

28-April-2015 V. Uzhinsky hadr-partonstring-mgt-V10-01-00
   Improved debug diagnostic.

 8-Sept-2014 V. Uzhinsky hadr-partonstring-mgt-V10-00-03
   Cosmetic cleaning of G4InteractionContent, G4VParticipants, G4VSplitableHadron
   Debuging option is added in G4VPartonStringModel.

24-April-2014 V.Uzhinsky hadr-partonstring-mgt-V10-00-02
   G4VPartonStringModel.cc was improved to treat an ExcitedString when
   it is a hadron stored as a Track of the ExcitedString. It is needed
   for a correct processing of quark-exchange processes in FTF model.

21-April-2014 V. Uzhinsky hadr-partonstring-mgt-V10-00-01
   A bug was erased in G4VPartonStringModel.cc. It appears at a debugging
   when a residual nucleus mass number =0.

13-Mar-2014 G. Cosmo hadr-partonstring-mgt-V10-00-00
-  Fix to remove 'inline' qualifier from methods in G4VParticipants.cc
   and G4PomeronCrossSection.cc, responsible for run-time errors for
   undefined symbols in library...

29-Jan-2013 V. Uzhinsky had-partonstring-mgt-V09-06-04

27-Sep-2012, G.Cosmo
- Explicitly use inclusion of headers for system of units and physical

  Status: 0 - spectator, 1 - involved nucleon, 2 - absorbed nucleon
  (G4VSplitableHadron)

  introsuced in G4InteractionContent.

10-July-2009 V. Uzhinsky  (had-partonstring-mgt-V09-02-00)
  Introduction the right tag number.

9-July-2009 V. Uzhinsky     (had-partonstring-mgt-V08-02-02)

  corresponding methods to operatite with it. It was needed for an
  absorption of meson in nuclear collision generated by FTF.

24-Apr 2007 Gunter Folger   (had-partonstring-mgt-V08-02-01)
- Merge ftf-dev back to head.

    G4FTFParameters.cc and .hh, and moved to diffraction directory.
    The corresponding class was re-named too. All of these characterize
    the content of the files more exactly.
