                      ---------------------
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 !

12 November 10: A.Schaelicke (empolar-V09-03-02)
- Resolved: Warning messages of Coverity 

3 September 10: G.Cosmo (empolar-V09-03-01) 
- Fixed signature to G4VPolarizedCrossSection::TotalXSection() in source file.

16 June 10: A.Schaelicke (empolar-V09-03-00)
- Bug fix in G4ePolarizedIonisation.cc
  (used default vector size of G4VEnergyLossProcess, 
   avoid size mismatch in G4LossTableBuilder::BuildDEDXTable)

12 November 09: A.Schaelicke (empolar-V09-02-01)
- Bug fix in G4PolarizationHelper::GetSpinInPRF 
    (wrong normalization of y component)
- Bug fix in G4PolarizedAnnihilationModel::PostStepDoIt
    (wrong treatment in error check) 
- Bug fix in G4StokesVector::RotateAz 
    (wrong usage of vector product)

12 April 09: V.Ivanchenko (empolar-V09-02-00)
G4PolarizedAnnihilationModel - simplified initialisation

30 October 08: A.Schaelicke (empolar-V09-01-01)
   For all process classes set sub-types according to the enumeration
05 November 07: A.Schaelicke (empolar-V09-00-02)
01 November 07: A.Schaelicke
- Bug fix in G4PolarizedAnnihilationCrossSection
    error in calculation of polarisation dependent total cross section
    (wrong interactionLength for positrons in applications where, 
     particle and media are polarised)  
- more general Cross section frame work:
    G4PolarizedAnnihilationCrossSection
    G4PolarizedBhabhaCrossSection
    G4PolarizedBremsstrahlungCrossSection
    G4PolarizedComptonCrossSection
    G4PolarizedGammaConversionModel
    G4PolarizedMollerCrossSection
    G4PolarizedPairProductionCrossSection
    G4VPolarizedCrossSection
    G4ePolarizedBremsstrahlungModel
   (removed dependencies to models; now cross sections can be used 
    independent of any model, e.g. in a cross section calculator class)
- add polarized photo electric effect:
    G4PolarizationHelper
       (new method GetRandomFrame, used when interaction frame is not
        well defined by outgoing particles) 
    G4PolarizedPEEffectCrossSection
       (based on McMaster, Rev.Mod.Phys. 33 (1961) 8)
    G4PolarizedPEEffectModel
       (derived from G4PEEffectModel, adds polarisation transfer)
    G4PolarizedPhotoElectricEffect
       (derived from G4VEmProcess)

02 October 07: V.Ivanchenko (empolar-V09-00-01)
G4eplusPolarizedAnnihilation - enabled AtRest

10 July 07: V.Ivanchenko (empolar-V09-00-00)
10 July 07: A.Schaelicke
- G4VPolarizedCrossSection removed obsolete methodes and variables to
  clear "shadow" Warning on SUN CC
- G4PolarizedCompton, G4ePolarizedIonisation,
  G4eplusPolarizedAnnihilation renamed local variable "particle" to
  avoid "shadow" Warning on SUN CC
- G4PolarizedAnnihilationModel
  copied Initialise() method from G4eeToTwoGammaModel provide a 
  ParticleChangeForGamma object, this avoids "shadow" Warning on SUNCC
  and reduces overhead in SampleSecondaries()

11 June 07: V.Ivanchenko (empolar-V08-03-02)
- (A.Schaelicke) G4PolarizedCompton, G4ePolarizedIonisation, 
  G4eplusPolarizedAnnihilation added method 
  PostStepGetPhysicalInteractionLength in order to provide 
  simulation of polarized target; the fix is required because of design 
  change in utils

25 May 07:  V.Ivanchenko (empolar-V08-03-01)
- G4PolarizedCompton - fix compilation warning and incorrect usage of 
                       G4PhysicsVector

23 May 07:  V.Ivanchenko (empolar-V08-03-00)
- In all processes inherit from G4VEnergyLossProcess or G4VEmProcess 
  remove method SecondaryPostStep;
- G4VEmModel - changed interface of SampleSecondary method, it become 
  void, extra parameter std::vector<G4DynamicParticle*>*, all
  classes using or inhereting this interface are modified.

19 March 07: V.Ivanchenko (empolar-V08-02-00)
- G4PolarizedGammaConversionModel : fix non-initialised variable

20 November 06: V.Ivanchenko (empolar-V08-01-04)
- G4PolarizedAnnihilationCrossSection fixed compilation problem at windows

17 November 06: V.Ivanchenko (empolar-V08-01-03)
- Add protection against zero kin energy in G4PolarizedAnnihilationModel
- substitue double -> G4double, int -> G4int, bool ->G4bool

10 November 06: V.Ivanchenko (empolar-V08-01-02)
9. November 06: A.Schaelicke
- G4PolarizedGammaConversionModel : add warning message if polarization
  transfer does not work properly
- G4PolarizedPairProductionCrossSection : bug fixed in Initialize(),
  and corrected spelling warning message
- G4PolarizedAnnihilationModel : SampleSecondaries() bug fixed in
  return statement and call to cross section.
- G4PolarizedAnnihilationCrossSection : Initialize() bug fixed in
  dicing and sign in cross section.
- G4PolarizedComptonCrossSection and G4PolarizedComptonModel:
  use correct convention of photon polarization vectors.
- G4PolarizedMollerBhabhaModel : bug fixed in eps dicing, added
  warning message, employ new cross section calculation (made conform
  to other polarized processes)
- G4PolarizedBhabhaCrossSection and G4PolarizedMollerCrossSection :
  new cross section calculation to make polarization vector conform to
  other polarized processes 

29 Sept 06: G.Cosmo (empolar-V08-01-01)
- Fixed for usage of std namespace and porting on WIN32-VC platform.

21 Sept 06: V.Ivantchenko (empolar-V08-01-00)
- First commit.
