                  Geant4 10.1 - patch-01 Release Notes
                  ------------------------------------
 
                                                             27 March 2015
 
 List of fixes included in this public patch since the public release 10.1:
 
   o Configuration:
     -------------
     + CMake:
       o Added support for compiling against c++1y standard for GNU and Clang
         compilers. Added support for compiling against c++11 standard for
         Intel 15 compiler. 'c++0x' is used for compilers with partial support
         (even if 'c++11' is allowed), reserving 'c++11' for fully supported
         cases.
       o Corrected search path for X11 libraries to ensure location of Xquartz
         libs on MacOSX. Addressing problem report #1683.
       o Added external USolids library to static linkage list.
         Addressing problem report #1725.
       o Ensure that system/compiler is correctly set for GNUMake compatibility
         on MacOSX.
 
   o Analysis:
     --------
     + Fixed G4AnalysisManager::IsActive(), now taken into all Hn & Pn managers.
     + Fixes in the Root files output to be compatible with ROOT 6.02/x.
     + Fixed reading XML ntuples with a column of a vector type; tools do not
       support direct use of ntuple_bindings with a vector, use of a temporary
       sub-ntuple is needed.
     + Fixed resetting histograms.
 
   o Digits & hits:
     -------------
     + Fix in CMake script of 'scorer' module for missing dependency on
       external library.
     + Added calls to G4VisManager::BeginDraw2D() and  G4VisManager::EndDraw()
       in G4VScoreColorMap to speedup drawing of texts and color chart.
       Revised Draw() DrawColumn() methods in G4ScoringBox and G4ScoringCylinder
       to speed up drawing primitive scorers attached to the scoring meshes.
 
   o Event:
     -----
     + Fix to reduce performance penalty in MT mode when using GPS with low
       energy primaries. Addressing problem report #1706.
 
   o Externals:
     ---------
     + USolids:
       o UPolycone: fix in InsideSection() for points(0,0,z). Fix in

         constructed by (r,z) corners.
         Use canonical form for operator=(). Code cleanup and formatting.
       o Added special DistanceAway() method for Inside() in order to fix
         precision problem in calculation of DistanceToSide() in UPolyconeSide.

       o Renamed ExceptionSeverity struct to UExceptionSeverity in UUtils to
         avoid possible clashes with external libraries.
       o UTrap: fix in SafetyToIn/SafetyToOut() for implementations which were
         reverted.
       o Fixed triangularisation method AddGeneralPOlygoneFacets() in
         UExtrudedSolid by avoiding flat triangles.
       o Added warning message to UTriangularFacet constructor if Area is 0;
         i.e. case of flat triangle.
 
   o G3toG4:
     ------
     + Fix to CMake script to include missing dependency on external library.
 
   o Geometry:
     --------
     + biasing:

         avoid data races when accessing iterators.
         Use const references for string in argument for constructor and
         accessor.
     + magneticfield:
       o Small refinements in G4FieldTrack: added method to access rest mass
         and avoid division by zero for unit direction.
     + navigation:
       o G4ErrorPropagationNavigator: revised implementation of ComputeStep(),
         to avoid calling G4Navigator::ComputeSafety().
         Addresses problem report #1679.
       o G4PathFinder: pass to equation of motion relevant properties of current
         particle: latest charge state, PDG spin value, momentum and rest mass
         of current particle. Fix in calls to ComputeSafety() to correctly
         use length as argument.
         Increased maximum number of navigators from 8 to 16.
         Addressing problem report #1696.

         of presence of 'rings' structures. Addressing problem report #1705.
       o Use canonical form for operator=() in G4PolyconeHistorical and
         G4PolyhedraHistorical.
     + volumes:
       o G4NavigationHistoryPool: moved printout from the destructor to
         dedicated Print() method.
       o Avoid post-increment in G4NavigationLevelRep::AddAReference().
       o Use canonical form for copy-ctor and operator=() in G4GRSSolid,
         G4GRSVolume, G4LogicalBorderSurface and G4LogicalSkinSurface.
 
   o Generic Processes:
     -----------------
     + Biasing:

         index 1.
     + Transportation:
       o G4Transportation, G4CoupledTransportation: in AlongStepGetPIL(),
         initialize restMass with G4DynamicParticle (as is used in DoIt()),
         not with G4ParticleDefinition. Resolves inconsistent kinematics
         when dynamic mass is measurably different from "PDG" mass.
 
   o Global:
     ------
     + Define support for c++11 thread_local keyword on Intel-icc compiler
       version 15.
     + Define G4THREADSLEEP(tick) macro in G4Threading header.
     + Updated date and version for 10.1.p01.
 
   o Graphics Representations:

   o Materials:
     ---------
     + G4Material, G4NistManager, G4NistMaterialBuilder, G4IonisParamMat:
       introduced NTP_Temperature=20C; set this temperature as default for 
       all materials instead of STP_Temperature. No effects in results expected.
       Addressing problem report #1704.
     + G4Material, G4Element, G4Isotope: make arguments of stream operators const.
 
   o Particles:
     ---------
     + Added missing gamma-gamma, omega-gamma modes to EtaPrime and updated
       braching ratio. Addressing problem report #1713.

     -------------
     + constructors/electromagnetic:
       o G4EmStandardPhysics_option4, G4EmStandardPhysicsWVI: disable
         'DisplacementBeyondSafety' option; result of electron scattering
         benchmark demonstrate some degradation of accuracy with this option
         enabled. Use step limitation option 'fUseDistanceToBoundary' instead.
       o G4EmStandardPhysicsWVI: added angular limit to WentzelVI model
         in order to provide correct backscattering.
         Addressing problem report #1702. For more information see:
         S. H. Kim et al., IEEE Trans. Nucl. Sci., vol. 62, no. 2, 2015.
     + constructors/hadron_elastic:

         with default, according to fix in cross_sections module for Chips
         neutron elastic cross-section.
     + constructors/limiters:
       o Fix in G4ParallelWorldProcess to correctly use method
         SetProcessOrderingToSecond().

     ---------------------------
     + dna:
       o Explicitly initialise to zero TLS pointers in G4KDNode and G4ITFinder
         to allow for compilation on Linux/clang-3.5.
     + highenergy:
       o G4eeToHadronsModel: fixed kinematics in ISR gamma emission; added
         check on energy balance. Addressing problem report #1716.

         simplify code.
       o G4GoudsmitSaundersonMscModel: return back to version of 10.0 with two
         fixes; trivial Coverity report, added protection against precision loss
         for small angle calculation, to ensure same backscattering results.
       o G4KleinNishinaModel: fixed very rare crash happening when de-excitation
         module is active and de-excitation energy is slightly larger than
         available energy; now secondary energy is slightly modified to keep
         energy balance instead of deleting secondary particle.
         G4PEEffFluoModel: use the same pattern as G4KleinNishinaModel for
         de-excitation products.
     + utils:
       o G4EmParametersMessenger: allow to set CSDA range flag only in the
         PreInit state to avoid crash in store/retrieve tables.
       o G4VEnergyLossProcess, G4VEmProcess, G4VMultipleScattering: allow for
         storing of physics table only from master thread.
       o G4VEmProcess: fixed printout at initialisation for the case when a
         process is shared between different particles.
         Fixed crash in printout for verbose level > 2.

         to address problem reported by CMS.
       o G4EmCalculator: fixed minor defect reported by Coverity.
 
   o Processes - Hadronic:
     --------------------
     + cross_sections:
       o Fix in G4ComponentGGHadronNucleusXsc to work for H target.
       o Removed obsolete (wrong) checks for particle types in IsIsoApplicable()
         in Chips cross sections.
       o Workaround in G4CrossSectionFactory<T,2>::Instantiate() to allow for
         compilation on clang-3.5 on Linux, for initialisation of TLS pointer.
     + models/coherent_elastic:
       o G4DiffuseElastic: fix for low-energy neutrons.
         Fix in theta_cms momentum transfer transformation.
         Fix for rare numerical error (sqrt of negative argument).
       o G4NuclNuclDiffuseElastic: fix for 700 MeV Be-ions scattering in Be.
         Addressing problem report #1691.
     + models/de_excitation:
       o G4VGammaDeexcitation::GenerateGamma(): take into account atomic bond
         energy for computation of transition energy and kinematics in the case
         of internal conversion. 
       o G4VGammaDeexcitation, G4DiscreteGammaDeexcitation, G4PhotonEvaporation:
         changed default set of parameters: ICM disabled; time limit for isomere
         production is set to DBL_MAX; sampling of gamma decay of long-lived
         isomere levels is performed as it was in Geant4 9.6 assuming decay at
         rest and making correction for energy balance (in that case momentum
         balance is not guaranteed); binding energy is taken into account in the
         case of ICM enabled. These modifications should provide correct sampling
         of the decay time for all type of levels, energy balance in hadronic
         interactions, and event reproducibility of hadronic transport.
       o G4VGammaDeexcitation, G4PhotonEvaporation: propagate vacant shell number
         after internal convertion allowing to enable  atomic de-excitation in
         radioactive decay.
       o Enabled ICM by default in G4NeutronRadCapture.
       o G4GEMProbability: added protection to avoid numerical problem seen
         in FTF_BIC physics-list where a nucleus get excited to 8 GeV.
       o G4DiscreteGammaTransition return back correction on shell number
         to avoid assert failure in simplified calorimeter.
       o G4ContinuumGammaDeexcitation: fixed Coverity report.
     + models/lend:
       o Fixed Coverity defect in G4GIDI_map.
     + models/neutron_hp:
       o Removed unnecessary code in G4NeutronHPInelasticCompFS.

         anti-sigma+ capture at rest on hydrogen.
     + stopping:
       o G4HadronStoppingProcess, G4MuonMinusBoundDecay: fixed time of muon 
         nuclear capture secondaries. Addressing problem report #1695.
       o Define index in the model cathalog inside PreparePhysicsTable() to
         avoid bad interference with EM physics.
