0140     User applications can still use CMake 2.8.X or above for configuration
0141     and compilation. It is however recommended to migrate to CMake 3.3 or

0151     geometrical regions dump.
0152     The new schema is fully compatible with old schema versions

0155     <A HREF="https://cern.ch/aidasoft/USolids">Unified Solids Library</A>,

0164 <LI>Updated Goudsmit-Sounderson multiple scattering model for e+-
0165     can be tested in various applications. A new electromagnetic (EM)
0166     physics constructor G4EmStandardPhysicsGS is provided
0167     for that.</LI>
0168 <LI>For applications which are using C++ interface to define parameters
0169     of EM physics, it is recommended to switch from usage of the
0170     G4EmProcessOptions class to the G4EmParameters class.
0171     This will guarantee coherent parameters definition also for multi-thread
0172     setup.</LI>
0173 <LI>Public methods and corresponding UI commands have been added to
0174     activate PAI, MicroElec, or DNA models in one or more Geant4 regions.</LI>
0175 <LI>In all ionisation processes which simulate energy loss along step
0176     the models' lowest energy limits, which force full energy deposition at
0177     a step independently on the material, are reviewed. A coherent and common
0178     approach is introduced, allowing the user to set the value of this limits
0179     via UI commands or the new interface class G4EmParameters.
0180     Introduction of a lowest energy allows to remove hidden tracking cuts
0181     and limits from elastic scattering and ionisation models.
0182     For very low-energy simulations these lowest energy limits may be set
0183     to zero.</LI>
0184 <LI>Added alternative Geant4-DNA physics models for liquid water.</LI>

0212     <TT>G4ENSDFSTATEDATA</TT> for its path to be set.</LI>
0213 <LI>In order to use <TT>ParticleHP</TT> for charged particles
0214     (protons, deuterons, tritons, He3 and alphas), an optional data

0237     <A HREF="https://cern.ch/aidasoft/USolids">Unified Solids Library</A>
0238     primitives, to replace the original Geant4 solids, as in the
0239     previous release. The path to an external installation of the USolids
0240     library (VecGeom version <TT>v00.01.00</TT>) should be specified.

0246 <LI>New UI commands and C++ interfaces to define parameters
0247     of EM physics are now provided. PAI models may be enabled per particle type
0248     and detector region on top of any EM physics configuration.
0249     For example, the UI command <TT>"/process/em/AddPAIRegion all Tracker"</TT>
0250     defines PAI model for all charged particles in Tracker region.
0251     MicroElec models for the Silicon and set of DNA default models for the liquid
0252     water may be also enabled via UI commands and C++ interface.</LI>
0253 <LI>In all ionization processes which simulate energy loss along step
0254     a lowest energy limit is introduced, which forces full energy
0255     deposition at a step independently on material. Its value may be
0256     changed via a new UI commands or through the interface class
0257     G4EmParameters. The default value is <TT>1 keV</TT>, for Opt3, Opt4,
0258     Livermore, and Penelope physics constructors lowest e+- energy is
0259     <TT>100 eV</TT>.</LI>
0260 <LI>By default lateral displacement sampling is disabled for muons, hadrons,
0261     and ions. To enable lateral displacement a new UI command should be used:
0262     <TT>"/process/msc/MuHadLateralDisplacement true"</TT>.</LI>
0263 <LI>G4UrbanMscModel has been updated: e+ corrections are added and a new
0264     optional algorithm to sample lateral displacement is introduced.
0265     The new lateral displacement sampling is used only in Opt3, Opt4,
0266     Livermore, and  Penelope EM physics constructors.</LI>
0267 <LI>A new implementation of the Goudsmit-Saunderson model for multiple-scattering
0268     is now used for e+- below 100 MeV in the G4EmStandardPhysicsGS
0269     constructor. It is available in the experimental physics-list
0270     FTFP_BERT_TRV.</LI>
0271 <LI>The single scattering model with Mott corrections may be enabled in the
0272     G4EmStandardPhysicsSS physics constructor using the new UI command:
0273     <TT>"/process/msc/UseMottCorrection true"</TT>.</LI>
0274 <LI>Ion/ion stopping power tables have been updated using new
0275     computations of A. Schinner.</LI>
0276 <LI>Introduced new G4LowEPPolarizedComptonModel for simulation of the
0277     Compton scattering of linear polarized gamma.</LI>
0278 <LI>Full Auger atomic de-excitation cascade simulation may be enabled
0279      via the new UI command: <TT>"/process/em/augerCascade true"</TT>.</LI>
0280 <LI>The usage of the more accurate atomic transition energies (Bearden data)
0281     can be enabled via the UI command:
0282     <TT>"/process/em/fluoBearden true"</TT>.</LI>
0283 <LI>Added alternative Geant4-DNA physics models for liquid water
0284     and extra DNA physics constructors.</LI>

0286
0287 <B>Hadronic physics</B>
0288 <UL>
0289 <LI>Improved simulation of low-energy, evaporated nucleons by Fritiof model
0290     coupled with Precompond-de-excitation model.
0291     It affects the energy response in hadronic showers: the visible energy
0292     in simplified calorimeters increases in not heavy absorber materials,
0293     e.g. Iron and Copper.</LI>
0294 <LI>A new model for nuclear gamma de-excitation model has been introduced.
0295     It affects the lateral shapes of hadronic showers: narrower showers
0296     are produced, especially for heavy absorber materials.</LI>
0297 <LI>The model <TT>NeutronHP</TT> has been merged into the <TT>ParticleHP</TT>
0298     model, which now extends the treatment of low-energy neutrons (below
0299     <TT>20 MeV</TT>) to charged particles: proton, deuteron, triton, 3He and
0300     alpha, with energies up to <TT>200 MeV</TT>.
0301     Note: users should be careful when using this model for charged particles,
0302     for various reasons: validation is not yet completed; only the inelastic
0303     interactions are included in this model, while the elastic interaction
0304     is treated independently by other Geant4 models; the TENDL data library is
0305     deployed, which means that ENDF VII(.r1) evaluated data is used only for
0306     the few cases where it is available, while, in all other cases,
0307     the data from TALYS nuclear model is utilized, which can lead to
0308     large uncertainties.
0309     In order to use ParticleHP for charged particles, the optional data set
0310     G4TENDL-1.0 is required.</LI>
0311 <LI>Substantial revision of the Radioactive Decay model:
0312     now using G4UAtomicDeexcitation to handle fluorescence and Auger electrons;
0313     improved energy conservation for IT and EC modes to order <TT>30 eV</TT>
0314     by using approximate shell energy method of A. Zoglauer;
0315     adapted to changes in particle category by providing a mass defect check
0316     between parent and daughter nuclei; removed dependence on local
0317     isotope table in favor of that in G4NuclideTable.</LI>

0331 <LI>Replaced the Chips neutron elastic cross-section with NeutronElasticXS
0332     one in all (non-HP) physics lists.</LI>
0333 <LI>The Glauber-Gribov kaon inelastic cross-sections are used in all physics lists
0334     (instead of either Chips or Gheisha cross-sections). </LI>
0335 <LI>In the QBBC physics list, the upper limit of Bertini has been reduced
0336     from <TT>12</TT> to <TT>4 GeV</TT>.</LI>
0337 <LI>The <TT>FTFP_BERT_TRV</TT> physics list uses now the standard EM option
0338     with the new Goudsmit-Saunderson multiple scattering model
0339     (i.e. G4EmStandardPhysicsGS). Moreover, the transition region
0340     between Bertini and Fritiof models has been reduced from <TT>[3, 12] GeV</TT>
0341     to <TT>[2, 4] GeV</TT>.</LI>
0342 <LI>The physics list <TT>QGSP_BIC_AllHP</TT> uses the <TT>ParticleHP</TT>
0343     model for charged particles (p, d, t, 3He, alpha) below <TT>200 MeV</TT>.
0344     Note: this requires some optional data libraries, which the user needs
0345           to download from the Geant4 web site.</LI>

0380 <LI>Expected reduction of memory per thread in multi-treaded mode.</LI>
0381 <LI>Due to increased precision in some models, the measured CPU performance
0382     for some cases of high energy EM shower in HEP calorimeters
0383     is ~1% slower with respect to the previous Geant4 release.</LI>

0387 <UL>
0388 <LI>Hadronic showers have changed in two aspects: increased visible energy
0389     in not heavy absorber materials (e.g. Fe and Cu);
0390     narrower lateral showers in heavy absorber materials (e.g. W and Pb).
0391     The change in energy response is mostly due to the development in the
0392     formation of the excited nuclear remnant in the Fritiof model.
0393     The change  in the lateral shape is mostly due to the new model for
0394     nuclear gamma de-excitation.</LI>
0395 <LI>In some cases simulations of hadronic showers in HEP calorimeters
0396     are faster up to 5% with respect to the previous Geant4 release.</LI>

0453 <UL>
0454 <LI>Use CMake Compile Features to setup C++ Standard.
0455     Removed setup of C++ Standard selection via compiler version checking.
0456     Created list of compile features required by Geant4.
0457     Maintain GEANT4_BUILD_CXXSTD option to allow user to choose between
0458     C++11 and C++14 standards. When newer standard is chosen, require that
0459     compiler supports at least one feature from that standard, and add all
0460     supported features of that standard to the required list.
0461     Updated setting of flags and standard used to obtain information from
0462     compile features.</LI>
0463 <LI>Always use libc++ with Apple Clang so that std-supporting library is
0464     used for C++11 mode on older Mac systems where libstdc++ is the default.</LI>
0465 <LI>Migrate output directories for build products to use same layout as
0466     install tree. For single mode generators (Makefiles/Ninja), products
0467     are output to a 'BuildProducts' subdir of the main binary dir which
0468     holds bin/lib directories as derived from requested install dirs.
0469     With multimode generators (Xcode/VS), 'BuildProducts' holds an extra
0470     directory layer, one per build mode, under which the same bin/lib
0471     structure is used.</LI>
0472 <LI>Updates for migration to CMake >= 2.8.12. Use generator expressions in
0473     setting of per-mode compile definitions for Geant4 libs.</LI>
0474 <LI>Removed -no-gcc in CMAKE_CXX_FLAGS when using Intel compiler, as gcc
0475     interoperability is required for use of C++11 features in cxxlib.
0476     Removed -i-dynamic from LDFLAGS, no longer supported.
0477     Corrected checking of Intel compiler to use better CMAKE_CXX_COMPILER_ID
0478     variable.</LI>
0479 <LI>Only allow use of system USolids, i.e. external installation of the
0480     package.</LI>
0481 <LI>Updated Apple Clang detection to work on Xcode-7.</LI>
0482 <LI>Correction to allow for both static and shared libs to be built on
0483     Windows.</LI>
0484 <LI>Added new GEANT4_USE_FREETYPE option (OFF by default), to allow user to
0485     enable Freetype support in analysis library.
0486     Added export of TOOLS_FONT_PATH to environment when Freetype support is
0487     enabled, pointing to the fonts/ subdirectory of Geant4's share directory.
0488     Added TOOLS_FONT_PATH to test environment when Freetype support enabled.</LI>
0489 <LI>Updated FindROOT.cmake script to provide compatibility with Root-6 and
0490     allow usage of ROOTConfig.cmake, if available.</LI>
0491 <LI>Changed default build mode for single config generators to RelWithDebInfo
0492    to match testing system and UNIX conventions.</LI>
0493 <LI>Added new MSVC only option GEANT4_BUILD_MSVC_MP, defaulting to OFF.
0494     When ON, it prepends /MP to CMAKE_CXX_FLAGS to enable file level parallel
0495     compilation on Windows.</LI>
0496 <LI>Allow user to force search for Qt4 only when GEANT4_USE_QT is selected.
0497     Requested on HN User Forum #1766.</LI>
0498 <LI>Put CLHEP version 2.3.1.x as the minimum required.</LI>
0499 <LI>Updated data-sets versions.</LI>

1827   <LI>Replaced calls to IsWorkerThread() by <TT>G4Threading::IsMasterThread()</TT>.</LI>
1828   <LI>Fixed issue for random-number strong-reproducibility in MT mode.
1829       A new UI command has been introduced to allow to run in MT mode
1830       by forcing the random generator engine to use a specified state
1831       (stored in a file) for each event:
1832       <TT>"/random/resetEngineFromEachEvent true"</TT>. It looks for
1833       the files <TT>runXevtY.rndm</TT>, where <TT>X</TT> is the
1834       run-number (starting from 0), and <TT>Y</TT> is the event-number
1835       (starting from 0): if these files are not found, then the reseeding
1836       is ignored and the run proceeds as usual.
1837       This command allows to test the strong reproducibility in pure MT mode,
1838       e.g. to re-run a single event with the starting random engine status
1839       <TT>G4Worker3_run0evt5.rndm</TT> it is enough to rename (or copy) it
1840       as <TT>run0evt0.rndm</TT> and use the above UI command.

1842   <LI>Invoking <TT>G4ParticleTable::DestroyWorkerG4ParticleTable()</TT> in

1875     <LI>New interface in G4VViewer for multi-threading.</LI>
1876     <LI>Re-implemented graphics system fallback strategy. A graphics system may
1877         have more than one nickname. This is used for finding a fallback graphics
1878         systems when, for example, a Qt session is requested but the user has not
1879         instantiated a Qt session, or when interactive graphics systems are
1880         prohibited, as in batch mode.<BR>
1881         This allows the user to run an application
1882         that is fully configured with all available graphics systems, even under
1883         circumstances for which the primary graphics system is inappropriate. For
1884         example, it allows one to make a image with these commands in a batch
1885         macro: <TT>"/vis/open OGL"</TT>, <TT>"/vis/drawVolume"</TT>,
