                 Geant4 5.0 - patch-01 Release Notes
                 -----------------------------------

                                                      24th February 2003

List of fixes included in this public patch to release 5.0:

  o Config:
    ------
    - Added experimental setup WIN32-VC7.gmk for Windows .NET VC++ compiler.
    - Generalised identification of WIN32 specific setups in core scripts.
    - Forced silent generation of dependencies.
    - Configure script: fixed GNUmakefile access problem for correct execution
      of flags/libs command options. Added automatic recognition of 'Darwin' OS.
    - source/GNUmakefile: included patch to release 5.0.

  o Electromagnetic processes (low-energy):
    --------------------------------------
    - Minor fix in G4QAOLowEnergyLoss to use G4Poisson distribution.

  o Electromagnetic processes (standard):
    ------------------------------------
  + standard:
    - Fix for compound materials in G4eBremsstrahlungModel.
    - Minor fix in G4PAIonisation and G4PAIxSection to use G4Poisson
      distribution.
  + muons:
    - Fix for compound materials in G4MuBremsstrahlungModel and
      G4MuPairProductionModel.
  + xrays:
    - G4VXTRenergyLoss: removed reduntant headers inclusions and ordered
      inclusion for complex numbers to allow porting on Windows .NET VC++.
    - Minor fix in G4Cerenkov, G4ForwardXrayTR and G4VXTRenergyLoss to use
      G4Poisson distribution.

  o General processes:
    -----------------
  + optical:
    - Fix in calculation of polarization for perpendicular incidence
      in G4OpBoundaryProcess. Fixes bug report #442.

  o Geometry:
    --------
  + magnetic-field:
    - Removed some redundant inclusions of headers.
  + management:
    - G4VSolid.cc: restored original conditions for extent clipping in
      method ClipPolygon().
  + solids/Boolean:
    - Added set/get functions Set/GetVolumesNameExtension() for volume-name
      extension in G4ReflectionFactory. By default now the factory assigns
      "_refl" postfix to name of reflected volumes/solids.
    - Assumed less strict condition in the G4ReflectionFactory::CheckScale()
      method, to avoid precision problems with imported rotation matrices.
  + solids/CSG:
    - G4Cons: enhanced treatment of phi-sections, according to
      algorithm used also in G4Tubs.
  + volumes:
    - Fix in G4GeometryMessenger to check for geometry closed when commands
      are applied. Command /geometry/navigator/reset and test commands apply
      only when system is in "Idle" state.
    - G4VCurvedTrajectoryFilter: fixed initialisation of data member
      in constructor. Fixes crash in visualization under in some setups.
    - G4IdentityTrajectoryFilter: added comments for the Software Reference
      Manual.

  o Global:
    ------
    - Exclude definition of min/max for Windows .NET VC++ compiler
      in globals.hh.
    - Use SystemOfUnits.h and PhysicalConstants.h from CLHEP instead of
      internal local copies.

  o Hadronic processes:
    ------------------
  + cross_sections
    o Fixed bug in Newton method for electro-nuclear cross-sections.
  + management:
    o Fixed a missing data-member initialization in G4InelasticInteraction.
      Fixes bug report #455.
    o G4EnergyRangeManager, G4HadronicProcess: adopt exception handling for
      'no model found' case.
  + models/chiral_inv_phase_space
    o Minor fix for memory leak.
    o Fixed calculation of the equivalent photon in electro-nuclear.
  + models/generator/de_excitation
    o Improved performance for gamma evaporation (~30%).
    o Minor fix in method G4ExcitationHandler::transform() when calling
      erase(), to allow porting on Windows .NET VC++ compiler.
  + models/generator/high_energy
    o G4TheoFSGenerator: fix for semantics change in track, added Clear()
      call to particle-change vector.
  + models/generator/scattering
    o Removed some redundant inclusions of headers.
  + models/generator/util
    o Critical fix for semi-infinite loop in G4Fancy3DNucleus and
      G4FermiMomentum.
  + models/low_energy
    o G4LEKaonZeroLInelastic, G4LEKaonZeroSInelastic: fixed virtual
      destructor.
  + models/neutron_hp
    o Fix in sampling of gammas, in case internal conversion data are
      available in breit frame.
    o Fixed recoil direction distribution for 14MeV neutrons in Silicon.
    o Fixed cases of uninitialised variables responsible for event
      irreproducibility.
    o Optimized usage of poisson distribution to adopt G4Poisson.
  + models/pre_equilibrium
    o Fixed warning.
  + models/radiative_decay
    o Fix in G4NuclearDecayChannel and G4RadioactiveDecay: adapted to new
      nuclear level manager.
  + util
    o Removed some redundant inclusions of headers.

  o Intercoms:
    ---------
    - Included G4VVisManager::Draw methods for hits and trajectories.

  o Parameterisations:
    -----------------
    - Updated header files to remove redundant header inclusions
      and properly order inclusion for complex numbers, to allow
      porting on Windows .NET VC++ compiler.
    - Minor fix in G4IrregularXrayTRmodel, G4VXTRdEdx and G4VXrayTRadModel
      to use G4Poisson distribution.

  o Persistency:
    -----------
    - Corrected inclusion of headers for constant and units from CLHEP
      in G4MCTSimParticle and G4MCTSimVertex.

  o Visualization:
    -------------
    - OpenInventor: removed erroneous additional transformation.
    - HepRep: modified G4HepRepFileSceneHandler::AddThis()
      to incorporate G4Attributes into the HepRep1 file.
      Moved some of HepRepXMLWriter's warning messages to debug blocks.
    - VRML: minor fix to VRML2 driver in G4VRML2SceneHandlerFunc to
      adopt G4String.
    - Included G4VisManager::Draw methods for hits and trajectories.

  o G3toG4 tool:
    -----------

      o Cosmetics in output for stepping verbose.
      o Minor improvements to specific UI commands.
    - extended/electromagnetic - TestEm2, TestEm4
      o Cosmetics in output for stepping verbose.
      o Minor improvements to specific UI commands.
    - extended/geometry/olap
      o Removed redundant inclusion of headers.
    - extended/biasing
      o Removed redundant inclusion of headers.
    - advanced - composite_calorimeter, xray_telescope
      o Removed redundant inclusion of headers.
