  high-energy hadronic inelelastic interaction is quasi-elastic or diffractive.
  Note that this can be used for both FTF and QGS hadronic string models.

## 2025-05-03 Vladimir Ivanchenko (hadr-man-V11-03-00)
- G4HadronicProcess - removed warning for the case when K0 and antiK0 are
    transformed into KS or KL.

    G4ThreadLocalSingleton pattern and removed deletion of extra processes
    to avoid double deletion at exit.

## 2024-05-27 Vladimir Ivanchenko (hadr-man-V11-02-01)
- G4HadronicProcessStore - fixed handling of rare processes: printout, 
    cross section maximum search, and deletion end of run.

## 2023-12-09 Vladimir Ivanchenko (hadr-man-V11-02-00)
- G4HadronicProcess - explicitly define cross section type per particle type,
    this should CPU performance for few %

## 2023-08-16 Vladimir Ivanchenko (hadr-man-V11-01-05)
- G4HadronicProcessStore - removed extra not needed empty lines from
    information printout

## 2023-07-14 Alberto Ribon (hadr-man-V11-01-04)
- G4HadronicProcess : reduced the number of warnings concerning kaon0 and
  anti_kaon0 (which are transformed in kaon0S and kaon0L) to max 1 warning
  per thread. 
  (This is useful for Fluka-Cern because it produces kaon0 and anti_kaon0.)

## 2023-03-29 Vladimir Ivanchenko (hadr-man-V11-01-03)
- G4HadronicProcess - added extra G4Exception for the case if worker cannot 
  share initialisation with master thread (problem #2528), diagnostic is
  improved
- G4HadronicProcessStore - avoid checks of environment variables, instead call 
  to G4HadronicParameters

## 2023-01-21 Vladimir Ivanchenko (hadr-man-V11-01-02)
- G4HadronicProcess - removed usage of DebugFlag and RandomFile

## 2023-01-17 Vladimir Ivanchenko (hadr-man-V11-01-01)
- G4HadronicProcess - moved several class members to be protected, which 
    is needed for hadron elastic process (and may be other processes)

## 2023-01-09 Vladimir Ivanchenko (hadr-man-V11-01-00)
- G4HadronicProcess - substitute access to environment variables by call to
  G4HadronicParameters

- G4HadronicProcess - make access to target nucleus public needed for 
    neutron general process

## 2022-07-01 Alberto Ribon (hadr-man-V11-00-04)
- G4HadronicProcess: removed the temporary check and protection introduced
  in the previous tag (see below). This is not needed any longer after 
  replacing the threshold used for checking the absolute energy 
  non-conservation from DLB_MAX (implying no checking at all) to 350 GeV
  (this value allows for cases where the residual nucleus is not produced,
   even when super-heavy nuclides are involved).

## 2022-06-16 Alberto Ribon (hadr-man-V11-00-03)
- G4HadronicProcess: temporary check and protection against the crashes
  that have been seen recently with neutronHP; when a secondary particle
  has a huge kinetic energy (i.e. higher than the max energy allowed in
  Geant4 hadronic physics - by default 100 TeV), a JustWarning is thrown
  and the particle is neglected (i.e. a corresponding G4Track object is
  not created).

## 2022-05-25 Alberto Ribon (hadr-man-V11-00-02)
- G4HadronicProcess: propagate the information on parent resonance
  (in the FillResults method, from G4HadSecondary to G4Track)

## 2022-05-14 Vladimir Ivanchenko (hadr-man-V11-00-01)
- G4HadronicProcess - implemented integral method
- G4HadXSTypes, G4HadXSHelper - new helper objects

  Windows).

3 January 2020 V. Ivanchenko (hadr-man-V10-06-00)
---------------------------------------------------
- G4HadronicProcess : for charge check assume, that all final electrons
  come from internal conversion

11 November 2019 A. Ribon (hadr-man-V10-05-07)
---------------------------------------------------
- G4HadronicProcess : in the method CheckResult, a short-lived secondary
  particle is allowed to have a dynamic mass which differ from the PDG mass
  by less than three times the particle's width.

17 October 2019 V. Ivanchenko (hadr-man-V10-05-06)
---------------------------------------------------
- G4HadronicProcess : for particle out of the mass shell correct
    kinetic energy in a way, that it is always above 10 keV;
    use std::getenv method recommended for concurrency

---------------------------------------------------
- G4HadronicProcess : fixed Coverity warnings

21 August 2019 V. Ivanchenko (hadr-man-V10-05-04)
---------------------------------------------------
- G4EnergyRangeManager : move operators to be private, removed
    obsolete method, removed G4HadronicException, instead in case of
    problem return nullptr
- G4HadronicProcess : do not use try/catch pattern to choose hadronic
    interaction; decrease limit on check of offshell mass from 1.5 MeV
    to 10 keV - fixed problem 2175; removed unused headers

13 July 2019 V. Ivanchenko (hadr-man-V10-05-03)
---------------------------------------------------

---------------------------------------------------
- G4EnergyRangeManager : fixed bug regarding the kinetic energy per nucleon
  in the case of anti-nuclei (the bug was harmless because one single model,
  FTFP, is used for all energies in the case of anti-nuclei projectiles).

03 June 2019 V. Ivanchenko (hadr-man-V10-05-01)
---------------------------------------------------
- G4HadronicProcess - removed try/couch pattern from computation of mean
    free path, removed final state random rotation

---------------------------------------------------
- G4HadronicInelasticProcess - removed default GHEISHA cross section

08 November 2018 V. Ivanchenko (hadr-man-V10-04-12)
07 November 2018 V. Ivanchenko (hadr-man-V10-04-10)
06 November 2018 V. Ivanchenko (hadr-man-V10-04-09)
---------------------------------------------------

---------------------------------------------------
- G4HadronicInteractionWrapper - removed as obsolete class

10 August 2018 A. Ribon (hadr-man-V10-04-07)
---------------------------------------------------
- sources.cmake, G4HadronicParameters : moved away class G4HadronicParameters
  in hadronic/util/ to avoid circular dependency between hadronic/management/
  and hadronic/cross_sections/ (the former has to depend on the latter, but
  not vice versa; hadronic/util/ does not depend on either).

6 August 2018 A. Ribon (hadr-man-V10-04-06)
---------------------------------------------------
- G4HadronicParameters : created new singleton to keep global hadronic
  parameters. For the time being, it has only the high-energy limit of
  hadronic physics (instead of spreading this value in many different
  files, as done up to now). The default value is set to 100 TeV.

14 July 2018 M.Maire (hadr-man-V10-04-05)

8 June 2018 J. Yarba (hadr-man-V10-04-04)
---------------------------------------------------
- G4HadronicProcess - use correct return type when calling CheckResult
  (from PostStepDoIt); otherwise the value of pointer 'result' does not
  get properly reset to NULL in case a non-conservation is detected,
  thus "bad" interaction does not get re-sampled

31 May 2017 V. Ivanchenko (hadr-man-V10-04-03)
---------------------------------------------------
- G4HadronicProcess, G4HadronInelasticProcess - added keyword
    "override", cleanup cross section scale factor and weights

    fixed compilation warning of CMSSW at gcc7.0.0

29 May 2017 V. Ivanchenko (hadr-man-V10-04-01)
---------------------------------------------------
- G4HadronicProcess - use const pointers and "nullptr" for
    G4Material and G4Element, use ComputeCrossSection(...) method,
    remove creation of new materials in run time inside
    GetElementCrossSection(..) method, all materials should
    be created in user code

09 May 2018  Alberto Ribon (hadr-man-V10-04-00)
---------------------------------------------------
- G4HadronicProcess : fixed warnings in gcc 8 regarding catching

   of G4RadioactiveDecay - already deleted somwhere else.

11 May 2017 V. Ivanchenko (hadr-man-V10-03-03)
10 May 2017 V. Ivanchenko (hadr-man-V10-03-00)

  if kaon0 or anti_kaon0 are present: if this the case, they are transformed
  into either kaon0S or kaon0L, with equal (50%) probability.

27 May 2016 V. Ivanchenko (hadr-man-V10-02-01)
---------------------------------------------------
- G4HadronicProcess - added flag of "integral" approach to take into
    account cross section change at a step; use nullptr;
    do not create new materials in the method GetElementCrossSection(),
    istead only try to find existing simple G4Material

18 April 2016 V. Ivanchenko (hadr-man-V10-02-00)
---------------------------------------------------
- G4HadronicProcessStore - call initialisation of all G4HadronicInteractions

30 October 2015  Gunter Folger    (hadr-man-V10-01-06)

21 September 2015  Dennis Wright  (hadr-man-V10-01-05)
------------------------------------------------------
- G4HadronicProcess::BiasCrossSectionByFactor : replace

      (it != "ElectroNuclear") &&
      (it != "PositronNuclear") )

    by

  if( (it != "photonNuclear") &&

18 September 2012 Michael Kelsey   (hadr-man-V09-05-16)
-------------------------------------------------------
- G4HadronicProcess:  Inherit from G4VRestDiscreteProcess, to unify "normal"
  and stopping/capture activities.  Change constructor signature to take
  G4HadronicProcessType argument (requires changes to all subclasses), use
  it to toggle base-class configuration flags.

21 May 2012 Gunter Folger    (hadr-man-V09-05-06)
---------------------------------------------------
-  E/p conservation fails only if both absolute and relative fail;
	effect: at low energies, compare to absolute limit, and at
	  high energies use relative limit; cross-over when limits cross,
	  or at absolute = Ekinetic * relative
   Charge, baryon non-conservation will make test fail as before.


10 May 2012 Gunter Folger    (hadr-man-V09-05-05)
---------------------------------------------------
-  Improve format of E/p conservation check printout
-  Ignore check for charge and baryon number conservation when limit is DBL_MAX

-  add method for energy non-conservation check; in case of non-conservation,
    re-sample the interaction. Limits are set in G4HadronicInteraction, and
    may be overridden for models; LEP and HEP override defaults, as these do not
    return the nucleus in teh final state.
   A test mode aborting events and reporting info on stderr is available, and
   triggered by a negative value in G4Hadronic_epReportLevel env. variable.
