        History file for hadronic/models/parton_string directory
        --------------------------------------------------------

This file should be used to summarize modifications introduced in the 
code and to keep track of all tags.

     ---------------------------------------------------------------
     * Please list in reverse chronological order (last date on top)
     ---------------------------------------------------------------
23 June 2008 V. Uzhinsky (hadr-prtn-V09-01-02)
   G4QGSMFragmentation.cc and G4LundStringFragmentation.cc were
   decoupled at calculation of formation time due to adding methods
   and member in G4VLongitudinalStringDecay class for manipulation
   with string tension.

   Memory leak was erased in G4QGSMFragmentation.cc and 
   G4VLongitudinalStringDecay.cc thank to Gunter.

18 June 2008 V. Uzhinsky (hadr-prtn-V09-01-01)
   Changes in G4ExcitedString class were tagged. They are needed for
   operation of FTF.

13 June 2008 V. Uzhinsky    (hadr-prtn-V09-01-00)
----------------------------------------------- 
1. String fragmentation was revised, and parameters were tuned.
2. FTF parameters were tuned for proton-proton interaction
3. FTF parameters for pion-nucleon interactions were determined very rouhgly
4. Quiasi-elastic hadron-nucleus scattering was implemented in FTF
5. Formation time was implemented in FTF, and string tension was tuned


25 May 2007 G.Folger       (hadr-prtn-V08-02-02)
-----------------------------------------------
- Seperate G4DiffractiveExcitation for FTF from QGS (see next entry by V.Uzhinsky) 
  - Add original G4DiffractiveExcitation to qgsm as G4QGSDiffractiveExcitation
  - Move G4SingleDiffractiveExcitation from management to qgsm ( not used
    elsewhere) 

25 May 2007   V.Uzhinsky 
-----------------------------------------------
- FTF model tuned for Pi+P interaction implemented
  Moved modified G4DiffractiveExcitation from management to diffraction

24 April 2007 G.Folger    (hadr-prtn-V08-02-01)
-----------------------------------------------
- Merge changes from V.Uzhinsky  from ftf-dev branch back to HEAD.
- Seperate modifications done in G4VLongitudinalStringFragmentation for FTF
   from original code for QGS.
-  This tag includes the subdirectory tags: 
     - had-partonstring-mgt-V08-02-00
     - hadr-qgsm-V08-02-02
     - hadr-string-diff-V08-02-00
     - had-hadronization-V08-02-02


1 March 2007 G.Folger     (hadr-prtn-V08-02-00)
-----------------------------------------------

- Add modifications of V.Uzhinsky on ftf-dev branch.
  Files in diffraction, management, hadronization and qgsm are affected. 


23 Nov 2005 Dennis Wright (hadr-prtn-V07-01-00)
-----------------------------------------------

- G. Folger fixed bug in hadronization/G4ExcitedStringDecay.cc
   (tag had-hadronization-V07-01-00)

- D. Wright created History file for parton_string directory

31 March 2008 V. Uzhinsky (hadr-string-diff-V09-01-00)
--------------------------------------------------------

- Elastic hadron intra-nuclear nucleon scattering was inserted in
  FTF model. This allows to simulate quasi-elastic and multi-particles
  production together.
- Small re-orangement of FTF model was done. G4FTFCrossSection modules
  were re-named into G4FTFParameters and moved to /diffraction
