0017 creation of symlinks, leading to errors at install time.

0047 symbols from Windows Kits code.
0048
0049 o Global:

0054 + Added windefs.hh header, including protections for double definition
0055 of global symbols from Windows Kits code.

0070 o G4EmModelActivator: fixed configuration of the default EM multiple
0071 scattering on top of any other physics configuration.
0072 Addressing problem report #2106.
0073 + constructors/gamma_lepto_nuclear
0074 o Fixed reports from Coverity; removed double delete in destructor of
0075 G4LENDBertiniGammaElectroNuclearBuilder.
0076 + lists:
0077 o LBE: updated cross-sections to avoid crashes caused by the removal of
0078 default Gheisha cross-sections, and to have consistency between elastic
0079 and inelastic cross-sections.
0080
0081 o Processes - Electromagnetic:
0082 ---------------------------
0083 + muons:
0084 o G4MuPairProductionModel: added Store/Retrieve data methods.
0085 Co-works with new data-set G4EMLOW-7.9.1.
0086 + standard:
0087 o G4BetheHeitler5DModel: added protection against negative argument of
0088 sqrt(), due to precision lost.
0089 + utils:
0090 o G4EmParameters, G4EmParametersMessenger: added new parameter to enable
0091 read of e+e- production table from file.
0092 Co-works with new data-set G4EMLOW-7.9.1.
0093
0094 o Processes - Hadronic:
0095 --------------------
0096 + cross_sections:
0097 o G4HadronInelasticDataSet: fixed wrong GHEISHA x-section.
0098 Addressing problem report #2220.
0099 + management:
0100 o G4HadronicProcess: for charge check assume that all final electrons
0101 come from internal conversion.
0102 + cascade:
0103 o G4CascadeCheckBalance: fixed outstanding problem of the interface with
0104 native pre-compound model, happening when in the default de-excitation
0105 internal electron conversion gets enabled.
0106 o G4CascadeInterface: fixed memory leak by deleting ltcollider in class
0107 destructor.
0108 o G4CascadeParamMessenger.cc: ensure that Bertini-specific commands get
0109 added to "/process/had/cascade/" UI directory, instead of
0110 "/process/had".
0111 + models/coherent_elastic:
0112 o G4ElasticHadrNucleusHE: for pi- and Z>1 reuse data structure computed
0113 for pi+ in order to reduce memory and CPU at initialisation; added new
0114 private methods to store/retrieve data tables. Co-works with new
0115 data-set G4EMLOW-7.9.1. Fixed Coverity report.
0116 Switch to parameterized model by cut on kinetic energy and not momentum.

0123 o In G4Radioactivation::AddDeexcitationSpectrumForBiasMode(), fixed
0124 memory leak. Addressing problem report #2164.
0125 o G4RadioactiveDecay, G4RadioactiveDecayBase: changed default verbosity
0126 from 0 to 1, and remove G4cerr wherever it occurs and replace it with
0127 G4Exception or G4cout.
0128 Increased verbosity thresholds in order to reduce printout size.
0129 o G4BetaPlusDecay: changed sign of daughterZ argument in
0130 G4BetaDecayCorrections according to problem report #2199.
0131 o Fixed Coverity warnings in G4RadioactiveDecay and
0132 G4RadioactiveDecayBase. Fixed uninitialized data in G4SFDecay.

0134 o G4HadronElasticProcess: removed forgotten try/catch pattern for
0135 target isotope selection.
0136 + stopping:
0137 o G4MuonicAtomDecay: fixed Coverity warning by addition of G4Exception.
0138
0139 o Visualization:
0140 -------------
0141 + OpenInventor:
0142 o Added include paths to Inventor to usage requirements on G4OpenInventor.
0143 Inventor does not yet support imported targets, and paths added by
0144 include_directories are now explicitly removed.
0145 Addressing problem report #2215
0146
0147 o Data sets:
0148 ---------
0149 + G4EMLOW-7.9.1:
0150 o Added a new directory mupair for double differential probability
0151 of e+e- pairs produced by muons or hadrons.
0152
0153 o Examples:
0154 --------
0155 + basic
0156 o Fixed comment for suggested command "/run/numberOfThreads" in macros.
