                 Geant4 10.0 - patch-02 Release Notes
                 ------------------------------------

                                                           13 June 2014

List of fixes included in this public patch since the public release 10.0.p01:

  o Configuration:
    -------------
    + CMake:
      o When static libraries are used, wrap G4physicslists library with flags
        suitable to import whole archive. Implemented for GNU, Clang and Intel
        compilers. Other compilers require further checks on flags and how to
        apply to single library. Functionality needed to support global
        registration of templated factories.
      o Fixup usage of shared/static builtin libraries. Ensure that shared
        builtins do not get linked to static. Added new component 'static'
        allowing user to select static Geant4 libraries if they are available.
      o Provide advanced option to select thread local storage model when
        building multithreaded. Supported default mode: initial-exec model.
      o Added zlib and g3tog4 to list of features that --has-feature
        recognizes and can query.
      o Added -DG4FPE_DEBUG to GNU/Clang flags for Debug build mode.
    + GNUMake:
      o Force loading of symbols for templated libraries in physics_lists
        module for global libraries.
        Defined LDFLAGS for Linux and Darwin targets accordingly.

        skipping internal Z sections.
      o Implementation of auxiliary methods in UTubs and UCons:
        SafetyFromInsideR(), SafetyFromOutsideR(),SafetyToPhi().
        These methods are used in Polycone for SafetyfromInside()
        calculations. SafetyFromInside() and SafetyFromOutside() are changed
        in order to avoid duplications.
      o Fix to DistanceToIn() for UBox in case of points located on edges.

  o Processes - Electromagnetic :
    ---------------------------
    + Adjoint:
      o G4VAdjointReverseReaction: added protection against potential infinite 
        loop; if cross-section correction exceeds 100 the total cross-section

        and make coherent use of G4 types.
    + Transportation:
      o Fixed time in case of zero step in G4CoupledTransportation.
        This caused a 'going back in time' error, when a zero step occurred
        in particular at the boundary of a parallel world volume when scoring.
        Addressing problem report #1017.
      o Corrected AlongStepDoIt() methods of G4Transportation and 
        G4CoupledTransportation, to adapt it to corrected signature for
        G4FieldTrack constructors, which now take PDG spin; modified to use
        different constructor for G4FieldTrack (no Velocity) and adapted to
        revised signature of G4ChargeState constructor.
      o Fixed Coverity defect in G4UserSpecialCuts.

  o Processes - Hadronic:
    --------------------
    + models/binary_cascade:
      o G4BinaryCasacde: improved calculation of mass, and of correction for

        Do not call G4PhysicsTable::clearAndDestroy() in destructors of 
        G4NeutronHPCaptureData, G4NeutronHPElasticData, G4NeutronHPFissionData
        G4NeutronHPInelasticData. Because G4PhysicsTable content are manged by
        allocators
      o Fixed bug in kinematics of residual nucleus in G4NeutronHPCaptureFS.
      o Fixes for minor memory leaks and code simplification for better
        stability.

        G4NeutronHPCapturem G4NeutronHPElastic, G4NeutronHPFission and
        G4NeutronHPInelastic.
    + models/parton_string:
      o Set the minimum energy to apply Reggeon-Cascade at 2 GeV
        (it was wrongly set to 5 GeV in G4 9.6.ref03, causing the bump at
        5 GeV in the calorimeter visible energy of FTFP_BERT physics list).
        It affects the calorimeter energy response of the physics list
        FTFP_BERT(_HP), only for showers of hadrons between 4 and 5 GeV.
      o Extended the vectors CandAQ, CandQ of G4FTFAnnihilation
        in the case of one quark - anti-quark string, in order to correctly
        handle antiproton - proton and antineutron - neutron annihilations.
        Prepared also for Anti_Delta-- and Delta++ annihilation.
        It is expected to affect only antiproton annihilations, with
        negligible effects on the simulation of hadronic showers.
      o G4LundStringFragmentation: fixed rare crashes in the case of
        anti_sigma+ capture at rest on hydrogen; and added protections
        against vector access outside the allowed range.
        Negligible effects on the simulation of hadronic showers.
      o Fix to remove 'inline' qualifier from methods in G4VParticipants
        and G4PomeronCrossSection source files, responsible for run-time
        errors for undefined symbols in library on clang-3.4 compiler.
    + stopping:
      o G4MuMinusCapturePrecompound: added simplified model for capture in
        deuterium and in He4; reduced number of trials to find neutrino
        4-momentum from 1000 to 100; added protection 1 keV for negative
        excitation energy, and substituted FatalException by JustWarning.
      o Fixes for Coverity defects in G4MuonMinusCaptureAtRest and
        G4AntiNeutronAnnihilationAtRest.

  o Readout:
    -------
    + Fixed Coverity defects.

  o Track:
    -----
    + Fixed G4FieldTrackUpdator to energy/momentum passed to field
      integration: first set rest mass, then update kinetic energy.
      The problem affects propagation in multiple geometries.

        in case 'glu'h' is missing. Addressing problem report #1618.


  o Examples:
    --------
    + Updated reference outputs.
    + extended/medical/DICOM:
      o Reshuffled code for printout in DicomHandler::CheckFileFormat().
    + extended/field/field04:

      o Corrections for crashes in MT mode.
    + extended/persistency/gdml/G01:
      o Correction to solids.gdml for 'para' solid, where angle unit was
        missing.
      o Added GDML sample mat_nist.gdml showing how to load a NIST material,
        although format is not part of the GDML schema yet (i.e. expected
        warning in schema validation).
