0112
0113 Listed here is some relevant information on developments included in this
0114 release.
0115 Note that for all users a full re-installation of libraries (or a full
0116 re-compilation) and a re-compilation of user applications is required.

0121 <UL>
0122 <LI>Added support for declaring headers of a source code module private.
0123     Headers declared private are not installed. Partial refactoring of
0124     modules.</LI>
0125 <LI>Removed deprecated GNUmake scripts for libraries build.</LI>

0132 <LI>The inheritance level for G4TouchableHistory has been removed, simplifying
0133     touchables handling. G4VTouchable is now a simple typedef of
0134     G4TouchableHistory, therefore forward declarations of G4VTouchable
0135     in the code will have to be promoted to concrete inclusion of the
0136     related header file.</LI>
0137 <LI>Unused concrete touchable types G4GRSSolid and G4GRSVolume have been
0138     retired and are no longer available.</LI>

0152 <UL>
0153 <LI>The default value of the time threshold for radioactive decays of ions -
0154     above which these decays are ignored - has been changed, from
0155     <TT>10^27 ns</TT> (i.e. about twice the age of the universe) to
0156     <TT>1 year</TT>. For applications where radioactive decays of ions do
0157     play an important role, it is recommended to increase the default time
0158     threshold of these decays to a very high value, e.g. <TT>1.0e+60 years</TT>.
0159     This can be done in either one of the following three ways:
0160     <OL>
0161     <LI>Via UI command, e.g.
0162         <TT>/process/had/rdm/thresholdForVeryLongDecayTime 1.0e+60 year</TT>,
0163         (command to be used after <TT>/run/initialization</TT>);</LI>
0164    <LI>Via C++ interface, e.g.
0165        <TT>G4HadronicParameters::Instance()->SetTimeThresholdForRadioactiveDecay( 1.0e+60*CLHEP::year )</TT>
0166        (to be placed in the main program before run initialization);</LI>
0167    <LI>Via the second parameter of the constructor of the class
0168        G4RadioactiveDecay (for analogue mode only) or G4Radioactivation
0169        (for both analogue or biased mode),  e.g.
0170        <TT>G4RadioactiveDecay( "RadioactiveDecay", 1.0e+60*CLHEP::year )</TT>
0171        or <TT>G4Radioactivation( "Radioactivation", 1.0e+60*CLHEP::year )</TT>
0172       (this is for custom physics lists, before run initialization).</LI>
0173    </OL>
0174    In the examples, the first method is adopted.</LI>
0175 <LI>Renamed classes for capture from G4ParticleHPCapture to G4NeutronHPCapture.
0176     Removed unused G4NeutronHP*.hh headers for elastic and inelastic.</LI>
0177 </UL>
0178
0179 <P> </P>
0180 <B>Persistency</B>
0181 <UL>
0182 <LI>The build of the persistency library, G4Persistency, has been split into

0190 <LI>In order to allow support of Qt6, OGL is temporarily diverted to TSG by default.
0191     If VTK is requested, due to compatibility issues, all other drivers that use OpenGL
0192     - GLES "toolssg" drivers and all OpenGL drivers - are not registered automatically

0238 <LI>New Quantum State Simulation (QSS) integration method, an alternative

0239     method of integration offering built-in interpolation capability and

0240     enabling faster finding of the intersection of the trajectory with

0241     surfaces.</LI>

0242 <LI>Added new G4VNavigation common navigation interface class and streamlined

0243     code in navigation classes to use the new common interface.</LI>

0244 <LI>Added new G4SafetyCalculator class, auxiliary to G4Navigator; used in
0245     G4Navigator in <TT>ComputeSafety()</TT> to avoid saving/restoring

0263 <LI>Removed most calls to environment variables in electromagnetic physics
0264     classes</LI>
0265 <LI>In G4UrbanMscModel, reduced number of re-computations of safety.</LI>
0266 <LI>Reviewed initialisation of static data in G4SeltzerBergerModel and
0267     G4eBremsstrahlungRelModel classes.</LI>
0268 <LI>In G4LivermorePhotoElectricModel, updated initialisation of static tables
0269     for thread safety and setting of shell cross-sections.</LI>
0270 <LI>New process G4XrayReflection to describe X-ray surface scattering based
0271     on data provided in <TT>G4EMLOW-8.5</TT>.</LI>
0272 <LI>New class G4MicroElecCapture for better estimation of the non ionizing
0273     energy deposition.</LI>
0274 <LI>Rewritten G4DNARuddIonisationExtendedModel G4DNA model, applicable for
0275     scaled energy interval from <TT>100 eV</TT> to <TT>100 MeV</TT>.</LI>
0276 </UL>
0277
0278 <B>Hadronic physics</B>
0279 <UL>
0280 <LI>Introduced a new, alternative set of parameters for the Fritiof (FTF) string
0281     model, meant to overcome the problem of too optimistic (i.e. narrow) pion
0282     shower energy resolutions in ATLAS calorimeters with respect to test-beam
0283     data. This new FTF tune is enabled only in the reference physics list
0284     FTFP_BERT_ATL.</LI>
0285 <LI>In G4RadioactiveDecay, changed default threshold for the time beyond
0286     which radioactive decays are ignored, from twice the age of the
0287     Universe to one year. The code has also been reviewed to use only one
0288     table of radioactive decay channels and streamlined code for thread
0289     safety.</LI>
0290 <LI>Major extension of the INCLXX model to handle antiproton annihilation
0291     at rest and in-flight. All INCLXX-based physics lists now use INCLXX for
0292     the antiproton annihilation at rest.
0293     Note that, for the time being, for in-flight antiproton annihilation, FTFP
0294     is still used in all physics lists.</LI>
0295 <LI>Implemented an accurate modeling of elastic resonant scattering in heavy
0296     nuclei by the use of the Doppler Broadening Rejection Correction (DBRC)
0297     algorithm. By default, this treatment is not activated; it can be switched
0298     on via the UI command: <TT>/process/had/particle_hp/use_DBRC true</TT>.</LI>
0299 <LI>Implemented interface allowing the coupling between Binary Cascade (BIC)
0300     and ABLA, i.e. using BIC for the cascade and then ABLA for the nuclear
0301     de-excitation.</LI>
0302 <LI>Extended Bertini model to allow the use of ABLA as alternative post-cascade
0303     nuclear de-excitation (the default de-excitation remains unchanged).</LI>
0304 <LI>New cross-section class G4ChargeExchangeXS for charge exchange process.</LI>
0305 <LI>Reviewed and updated the fermi_breakup model.</LI>
0306 <LI>Safer initialisation of static data in hadronic cross-section classes.
0307     Added new HP cross-section classes.</LI>
0308 <LI>Added classes for QMD model optimised for light ions, recommended
0309     for medical applications.</LI>
0310 </UL>
0311
0312 <B>Particles</B>
0313 <UL>
0314 <LI>Particle properties have been updated according to PDG-2023.</LI>
0315 </UL>
0316
0317 <B>Persistency</B>
0318 <UL>
0319 <LI>Added possibility to set alternative grammar for schema validation
0320     while reading a GDML file.</LI>
0321 </UL>
0322
0323 <B>Physics Lists</B>
0324 <UL>
0325 <LI>New physics list QGSP_BIC_HPT, similar to QGSP_BIC_HP, but with
0326     special treatment of elastic scattering of thermal neutrons activated.</LI>
0327 <LI>Added new physics lists to the physics factory, for <TT>HPT</TT> variants
0328     (i.e. with special treatment of elastic scattering of thermal neutrons)
0329     of physics lists with <TT>HP</TT> already present (FTFP_BERT_HPT,
0330     QGSP_BERT_HPT, QGSP_BIC_HPT, QGSP_BIC_AllHPT, FTFP_INCLXX_HPT,
0331     QGSP_INCLXX_HPT, Shielding_HPT, and ShieldingM_HPT).</LI>
0332 <LI>Introduced new physics list names to the physics factory, Shielding_HP and
0333     ShieldingM_HP, as alias of, respectively, Shielding and ShieldingM.</LI>
0334 <LI>Used in the FTFP_BERT_ATL physics list a new, specific, FTF tune meant to
0335     overcome the problem of too optimistic (i.e. narrow) pion shower energy
0336     resolutions in ATLAS calorimeters with respect to test-beam data.
0337     Note: for all other reference physics lists (e.g. FTFP_BERT), the default
0338     set of FTF parameters is applied; in order to enable the new tune in these
0339     physics lists, one can use, before initialization, either the UI command:
0340     <TT>/process/had/models/ftf/selectTuneByName energy-resolution-tune2023-v0</TT>
0341     or through C++ interface:
0342     <TT>G4FTFTunings::Instance()->SetTuneApplicabilityState(4, 1)</TT>.</LI>
0343 <LI>In INCLXX-based reference physics lists (e.g. FTFP_INCLXX, QGSP_INCLXX, etc.),
0344     INCLXX is used for antiproton annihilation at rest (instead of FTFP as
0345     before).
0346     Note: in order to use INCLXX for antiproton annihilation at rest in other
0347     physics lists, one need to modify the source code of the physics list by
0348     replacing the class G4StoppingPhysics with G4StoppingPhysicsWithINCLXX.</LI>
0349 <LI>Added new physics constructor for neutrino physics, G4NeutrinoPhysics,
0350     and its messenger. New constructors G4ChargeExchangePhysics and
0351     G4NeutrinoPhysics may be added on top of any modular Physics List.
0352     Both constructors have messengers with UI commands allowing to configure
0353     these new physics processes.</LI>
0354 <LI>Added a Boolean parameter to the Shielding physics list constructor
0355     which allows to use the new G4LightIonQMD model instead of the default
0356     QMD model.
0357     Note: the new model G4LightIonQMD provides more precise modelling than
0358     QMD for medical applications; for other applications, e.g. shielding,
0359     physics validation is needed to compare the two models.</LI>
0360 <LI>New physics list QBBC_ABLA, behaving as QBBC, but using the ABLA model
0361     for nuclear de-excitation, instead of precompound/de-excitation,
0362     for charged pions and nucleons projectiles.
0363     This is for testing, not yet recommended for physics studies.</LI>
0364 </UL>
0365
0366 <B>Processes - General</B>
0367 <UL>
0368 <LI>New submodule <I>channeling</I>, implementing fast-simulation channeling
0369     model in oriented crystals with Baier Katkov method for the calculation of
0370     radiation probability, radiation point and parameters of photon production
0371     as well as spectrum accumulation.</LI>
0372 </UL>
0373
0374 <B>Visualization and Interfaces</B>
0375 <UL>
0376 <LI>First version of the TSG_[QT,X11,XT,WINDOWS]_ZB sub drivers, allowing for
0377     interactive 3D rendering bypassing native graphics systems.</LI>
0378 <LI>TSGQt driver temporarily enabled by default with OGL driver choice,
0379     to allow support of Qt6.</LI>
0380 <LI>Updated and extended Vtk visualization driver with new features and
0381     fixes.</LI>
0382 <LI>Supporting first implementation of a no-frills GUI-side scene tree
0383     in the Qt GUI.</LI>
0384 <LI>Implemented a more flexible way of choosing a graphics system for
0385     visualisation, preserving the existing behaviour in all aspects.</LI>
0386 <LI>Implemented <I>generic cutaways</I> in visualization. Clips, sections and
0387     cutaways will now be available to *all* viewers (OpenGL still uses
0388     OpenGL clip planes. Use another driver, e.g., TSG, to get "generic

0389     cutaways").</LI>
0390 <LI>Enabled first-level support for Qt6.
0391     Fixed minimum supported version for Qt5 to be 5.9.</LI>
0392 <LI>In G4UIQt, implemented right-click pop-up menu for touchables in new
0393     scene tree.</LI>
0394 </UL>
0395
0396 <B>Examples</B>
0397 <UL>
0398 <LI>New Geant4-FLUKA interface and two hadronic examples, providing access to
0399     FLUKA-Cern hadron-nucleus inelastic physics.</LI>
0400 <LI>New advanced example <TT>xray_TESdetector</TT> of the application of Geant4
0401     in a space environment. It represents an x-ray detector derived from the
0402     X-IFU, the X-ray spectrometer designed and developed by the European Space
0403     Agency (ESA) for use on the ATHENA telescope</LI>
0404 <LI>New advanced example <TT>xray_SiliconPoreOptics</TT>, demonstrating an
0405     application of Geant4 in space environment. The geometry represents a
0406     single reflective pore used to simulate on a smaller scale the effect
0407     of the millions of pores forming the mirror of the ATHENA Silicon Pore
0408     Optics (SPO).</LI>

0570 <LI>Added new G4AnalysisManager functions for deleting selected

0571     histograms, profiles and n-tuples, with related UI commands:

0572     <TT>/analysis/[hn|pn]/delete id [keepSetting]</TT>.</LI>

0573 <LI>Added <TT>GetNtuple()</TT> functions in G4GenericAnalysisManager,

0574     that in difference from output specific managers, returns n-tuple

0575     booking, that is common to all output types.</LI>

0576 <LI>Added UI commands for creating n-tuple:

0577     <TT>/analysis/ntuple/create name title</TT>,

1177     <LI>G4HadronicParameters: introduced the neutron kinetic energy threshold

1178         for  applying the SVT (Sampling of the Velocity of the Target)

1179         algorithm. This is needed to have a consistent value in methods

1180         <TT>GetBiasedThermalNucleus()</TT> in G4Nucleus and

1181         G4ParticleHPElasticFS respectively, to avoid circular dependency

1182         with <TT>particle_hp</TT> module.

1183         Removed two obsolete environment variables and access methods; added

1184         flag for charge exchange.

1185         Added class members defined via environment variable and access methods

1186         for these members, this allows to remove the majority of calls to

1187         <TT>std::getenv()</TT>.

1188         Added two strings and extra methods to access environment variables

1189         used in G4HadronicProcessStore. These variables are not used in

1190         ordinary runs but are checked in each thread and for each particle.

1191         With this update these variables will be checked only once.

1192         Added G4Exception for the case, when environment variable

1193         <TT>G4PARTICLEXSDATA</TT> is not defined.

1194         Added extra Boolean method for accessing debug flag for Binary Cascade,

1195         which may be defined via environment variable

1196         <TT>G4BINARY_CASCADE_DEBUG</TT>.

1197         Introduced methods to get and set the time threshold of radioactive

1198         decays (i.e. radioactive decays that happen later than this value are

1199         ignored), offering a C++ interface to set this parameter.

1200         Added getters and setters of recommended energy limits in physics lists

1206         and corrected the way to pass the last parameter, by reference instead

1207         of by value.

1208         Split the method <TT>GetBiasedThermalNucleus()</TT> into two parts, by

1209         introducing a new public method,

1210         <TT>DoKinematicsOfThermalNucleus()</TT>,

1211         which is used also by G4ParticleHPElasticFS to implement the DBRC

1216     <LI>G4AblaInterface: implemented method ApplyYourself() to allow the

1222     <LI>Extended Bertini model to allow the use of ABLA as alternative

1223         post-cascade nuclear de-excitation (the default de-excitation remains

1224         unchanged).

1225         There are two ways to set ABLA as de-excitation for Bertini: via C++

1226         interface, by calling <TT>G4CascadeInterface::useAblaDeexcitation()</TT>,

1227         and via environmental variable, by setting

1228         <TT>G4CASCADE_USE_ABLA=1</TT>.</LI>

1229     <LI>G4AblaDeexcitation: new class that does the nuclear de-excitation,

1231         the secondaries in Bertini objects.</LI>

1232     <LI>G4CascadeInterface: added new method <TT>useAblaDeexcitation()</TT>

1233         which sets ABLA as nuclear de-excitation; this method can be called

1234         directly by the user, or automatically in the constructor of the class

1235         when the flag <TT>G4CascadeParameters::useAbla()</TT> is enabled.</LI>

1236     <LI>G4InuclCollider: added new method <TT>useAblaDeexcitation()</TT> which

1260         for the case when data on internal conversion (IC) are not available; if

1261         IC is disabled, it is assumed that all IC transitions are performed from

1262         the K-shell, which means that independently on IC flag the probability

1263         of gamma transition is unchanged. For G4PhotonEvaporation, still use

1264         only gamma transitions for the case of nuclear level without information

1265         (as in version 11.2-beta).</LI>

1266     <LI>G4LevelManager: added extra public accessor method allowing users to

1329         methods, related to the DBRC algorithm.

1330         In G4ParticleHPMessenger, added new UI commands to enable DBRC (which

1331         is off by default) and to specify its parameters.

1332         In G4ParticleHPVector, added new method <TT>GetMaxY()</TT> to provide

1333         the maximum cross-section in the interval between two kinetic energy

1334         values.

1335         In G4ParticleHPChannel, modified method <TT>ApplyYourself()</TT>,

1336         with an extra argument, for a special treatment of the elastic channel.

1423         Created new class G4BetaSpectrumSampler to sample a sloped distribution

1424         instead of a flat one. Changed G4BetaMinusDecay and G4BetaPlusDecay to

1425         use the above sampler. Added protection against very large arguments

1426         in <TT>std::exp()</TT> within

1427         <TT>G4BetaDecayCorrections::ModSquared90</TT>.</LI>

1428     <LI>G4RadioactiveDecay: changed default threshold for the time beyond

1429         which radioactive decays are ignored, from twice the age of the

1430         Universe to one year.

1431         Use only one table of radioactive decay channels;

1432         removed unnecessary MULTITHREADED blocks protections; removed lock from

1433         class constructor; added use only lock in the method

1434         <TT>LoadDecayTable()</TT> after the check if the table is already

1435         downloaded; added explicit unlock in this method; removed counter

1436         of instances of the class.

1437         Made all virtual methods override and moved implementations to source.

1438         <TT>DecayIt()</TT> method is declared virtual; removed unused methods;

1439         use reference instead of by-values in method signatures for complex

1440         objects; added G4ITDecay object local for each thread to perform

1441         sampling of radioactive decays with a possibility to sample

1442         correlated gamma emission. Fixed initialisation printout: corrected

1443         place for triton printout.</LI>

1444     <LI>G4RadioactiveDecay, G4Radioactivation: added an extra parameter in the

1445         constructor, to be able to set the threshold for the time beyond which

1446         radioactive decays are ignored. This is meant for custom physics lists.

1447         Moreover, the constructor of these classes has been modified to offer

1448         also a C++ interface, via the singleton G4HadronicParameters, to set

1449         the same time threshold for radioactive decays. This is meant for

1450         reference physics lists. Note that, in the unlikely and weird scenario

1451         that two time thresholds are specified - one via G4HadronicParameters,

1452         and one via the constructor parameter - the larger of the two is

1453         considered, to be conservative. In all cases, an eventual time

1454         threshold specified via UI command prevails on anything else.</LI>

1455     <LI>G4Radioactivation: marked all virtual methods as <TT>override</TT>

1456         and moved implementations to source; marked <TT>DecayIt()</TT> as

1457         <TT>override</TT>; removed methods <TT>GetDecayTable1()</TT>,

1458         <TT>AtRestDoIt()</TT> and <TT>PostStepDoIt()</TT>, use instead base

1459         class methods.</LI>

1524     In <TT>SceneTreeItemClicked()</TT>, make daughters invisible when volume

1525     checked invisible, pop up a window of explanation; in

1746         <LI>New class G4HadronInelasticQBBC_ABLA, similar to

1747             G4HadronInelasticQBBC_ABLA, except that for the final-state of

1748             nuclear inelastic interactions of charged pions and nucleons

1749             projectiles, the ABLA model is utilized for nuclear de-excitation,

1750             instead of the usual precompound/de-excitation.

1751             Meant for testing purposes. In principle, these couplings with ABLA

1752             nuclear de-excitation can be extended to all types of projectiles

1753             and to other reference physics lists, but, for the time being, it

1754             is restricted to pion+, pion-, proton and neutron, and only for

1781         ATLAS calorimeters with respect to test-beam data.</LI>

1782     <LI>Use the new class G4StoppingPhysicsWithINCLXX (instead of

1783         G4StoppingPhysics) in INCLXXPhysicsListHelper: this implies that all

1784         the INCLXX-based physics lists (FTFP_INCLXX, QGSP_INCLXX, etc.) use

1785         INCLXX for the antiproton annihilation at rest.</LI>

1786     <LI>Introduced the new class QGSP_BIC_HPT, which is similar to QGSP_BIC_HP,

1787         but with special treatment of elastic scattering of thermal neutrons

1788         activated.</LI>

1789     <LI>G4PhysListFactory: added new physics lists, corresponding to

1790         <TT>HPT</TT> variants (i.e. with special treatment of elastic

1791         scattering of thermal neutrons) of physics lists with <TT>HP</TT>

1792         already present (FTFP_BERT_HPT, QGSP_BERT_HPT, FTFP_INCLXX_HPT,

1793         QGSP_INCLXX_HPT, QGSP_BIC_HPT, QGSP_BIC_AllHPT, Shielding_HPT, and

1794         ShieldingM_HPT).

1795         Of these, only one (QGSP_BIC_HPT) corresponds to a concrete new physics

1796         list, whereas the others are obtained from the <TT>HP</TT> physics

1797         lists by adding the physics constructor G4ThermalNeutrons.

1798         Introduced new physics list names Shielding_HP and ShieldingM_HP, as

1799         alias of, respectively, Shielding and ShieldingM. These new aliases

1800         allow to have a consistent notation _HPT for all the HP-based physics

1801         lists when the special elastic scattering treatment of thermal neutrons

1802         is enabled.</LI>

1803     <LI>Shielding: added information note that the new physics list names (to

1804         be used with the physics list factory), Shielding_HP and ShieldingM_HP,

1805         are equivalent to, respectively, Shielding and ShieldingM.

1806         Added a option for Shielding to use G4LightIonQMDPhysics, which is

1807         the constructor of light ion QMD.</LI>

1808     <LI>G4PhysListFactoryMessenger: added the new UI command

1809         <TT>/physics_lists/factory/addThermal</TT> to enable the special

1810         treatment of elastic scattering of thermal neutrons for HP-based

1811         physics lists. Added UI commands to enable neutrino and

1812         charge exchange physics.</LI>

1813     <LI>QGSP_BERT_HP: use alternative HP models and cross-sections.</LI>

1814     <LI>QGSP_BERT_AllHP: use default HP elastic builder.</LI>

1815     <LI>New class QBBC_ABLA, which is similar to QBBC, except that for

1816         hadron inelastic the constructor G4HadronInelasticQBBC_ABLA is used,

1817         instead of G4HadronInelasticQBBC. This means that the physics list

1818         QBBC_ABLA behaves as QBBC, with the only difference that for the

1819         final-state of nuclear inelastic interactions of charged pions and

1820         nucleons projectiles, the ABLA model is being used for nuclear

1821         de-excitation, instead of the usual Precompound/de-excitation.</LI>

1873     <UL>

1874     <LI>Implemented a more flexible way of choosing a graphics system.

1875         It preserves the existing behaviour in all aspects.

1876         To take advantage of the new ways, <TT>/vis/open</TT> should be

1877         allowed to use default parameters, either by omitting them

1878         altogether or by using '!'. Without any change of code, i.e.,

1879         using the existing constructor, G4VisExecutive will refer to the

1880         environment variable <TT>G4VIS_DEFAULT_DRIVER</TT>, which should

1881         contain the nickname of the chosen graphics system and, optionally,

1882         a window size hint (space separated).

1883         Or on the command line, precede the app invocation,

1884         (e.g: <TT>G4VIS_DEFAULT_DRIVER=Vtk 'application-name'</TT>).

1885         The window-size-hint can optionally be added to all these options,

1886         e.g: <TT>(bash) export G4VIS_DEFAULT_DRIVER="OGLSX 1000x1000-0+0"</TT>.

1887         Otherwise G4VisExecutve will choose a graphics system on the basis of

1888         batch/interactive running, and Geant4 build options (see list

1889         of registered graphics systems printed at the start of job).</LI>

1890     <LI>Further ways are available by using a new constructor,

1891         <TT>G4VisExecutive(argc, argv)</TT>. This follows G4UIExecutive usage.

1892         If a 3rd argument is supplied, this is your chosen system

1893         (e.g.: <TT>G4VisExecutive(argc, argv, "Vtk")</TT>).

1894         Otherwise, it looks at <TT>G4VIS_DEFAULT_DRIVER</TT>, as above.

1895         Otherwise, it inspects <TT>~/.g4session</TT>.<BR>

1896         G4UIExecutive behaviour is preserved.<BR>

1897         Otherwise, as above, it will choose a graphics system on the basis of

1898         batch/interactive running, and Geant4 build options.</LI>

1899     <LI>G4VisExecutive: added new constructor implementing default graphics

1900         system by environment variable <TT>G4_VIS_DEFAULT_DRIVER</TT>.

1901         Simplified default graphics system by run option (batch/interactive).

1902         Exploit new method, <TT>G4UImanager::GetBaseSession()</TT>.

1903         Added code for default graphics system based on batch or build

1904         flags. In <TT>SetDefaultsByBuildFlags()</TT>, added missing default

1905         for TOOLSSG...ZB drivers.

1906         Temporary divert OGL to TSG for allowing support of Qt6.

1907         Declare TOOLSSG_[X11,XT,WINDOWS,QT]_ZB drivers.

1908         Fixed default TSG nickname when Vtk suppresses OpenGL.

1909         Added single line message "VTK: OpenGL-based drivers suppressed".

1910         Protect all G4cout statements with <TT>fVerbosity</TT> at startup.</LI>

1911     <LI>Implemented choice by argument and by <TT>~/.g4session</TT>.</LI>

1912     <LI>G4VisManager: improved messaging in

1913         <TT>PrintAvailableGraphicsSystems()</TT>.

1914         Improved readability of code that ignores deleted histograms, etc.

1915         Improve printing about histograms that can be plotted in the UI

1916         session. Take into account deleting histograms in G4VisManager:

1917         the vector of histograms can contain 'nullptr' elements.</LI>

1918     <LI>Introducing concept of default XGeometryString (aka window size

1919         hint).</LI>

1920     <LI>G4VisCommandsCompound: in <TT>/vis/open</TT>, exploit "current as

1921         default" for all parameters, including the window-size-hint.</LI>

1922     <LI>G4VisCommandsViewer: in <TT>/vis/viewer/create</TT>, exploit

1923         "current as default" for all parameters, including the

1924         window-size-hint.</LI>

1925     <LI>Introducing scene tree in G4VViewer. The scene tree is a tree of

1926         G4SceneTreeItem objects; its root is a data member fSceneTree of all

1927         viewers by virtue of G4VViewer inheritance. The root G4SceneTreeItem

1928         has children that represent the models (G4VModel sub-classes) in the

1929         scene. For a G4PhysicalVolumeModel (detector components), its children

1930         and children's children, etc., imitate the geometry hierarchy of that
1931         model. These descendants are called "touchables". There may be more
1932         than one G4PhysicalVolumeModel, depending how the user creates his/her
1933         scene. The scene tree is reviewed, and updated if necessary, at every
1934         pass of <TT>G4VSceneHandler::ProcessScene()</TT>. This is called a
1935         "kernel visit". A kernel visit is triggered by vis commands (e.g.,
1936         <TT>/vis/viewer/rebuild</TT>) and by a viewer if deemed necessary.
1937         For example, a kernel visit may not be required for a rotation, zoom,
1938         etc., but required for a change from surface to wireframe. The idea
1939         is that the scene tree can be passed to a GUI, the GUI can create a
1940         tree widget, and interactions with it raise UI commands such as
1941         <TT>/vis/scene/activateModel</TT>, <TT>/vis/set/touchable</TT> and
1942         <TT>/vis/touchable/set/</TT>...
1943         The viewer decides if this requires a kernel visit, otherwise it must
1944         update <TT>fSceneTree</TT> itself (utilities are provided).
1945         Limit the depth of expansion of the scene tree touchables; this is to
1946         prevent the trees of complex detector running off the page; all
1947         touchables are entered but could be in a collapsed item, viewable by
1948         expanding the mother with a left click.
1949         Added scene tree and related functionality.
1950         Improved <TT>G4VViewer::SceneTreeScene::FindOrInsertTouchable()</TT>.
1951         Simplified ghost-touchable transition.
1952         Added "utility" function <TT>UpdateGUISceneTree()</TT>.
1953         Applied clang-format.</LI>
1954     <LI>New scene tree: implementing expand and collapse of touchables.
1955         Expand only to depth 2, thereafter sub-trees are collapsed.
1956         When the scene tree is expanded or collapsed it is remembered in
1957         the viewer-side scene tree and may be propagated to other viewers.</LI>
1958     <LI>First implementation of a no-frills GUI-side interactive scene tree.
1959         Works with touchables; can change the visibility of a touchable.
1960         A view can be prepared with a graphical driver, such as OGL, TSG, OI
1961         or Vtk, and transferred it to Ray Tracer, TOOLSSG_OFFSCREEN, etc.,
1962         simply with <TT>/vis/open RayTracer</TT>, etc.</LI>
1963     <LI>Default special mesh rendering for viewers which can render all
1964         objects.</LI>
1965     <LI>Implemented "generic cutaways". It relies on the Boolean Processor
1966         which handles the Boolean operations on polyhedral representations of
1967         solids. Clips, sections and cutaways will now be available to *all*
1968         viewers (OGL viewers still use OpenGL clip planes).</LI>
1969     <LI>G4VSceneHandler: protect material pointer used to name G4Mesh item.
1970         If null, use name of container. It avoids cases of crash when a G4Mesh
1971         is in a parallel world. In <TT>RequestPrimitives()</TT>, improved test
1972         for invalid Boolean solid.
1973         In <TT>CreateSectionSolid()</TT> and <TT>CreateCutawaySolid()</TT>,
1974         improved algorithms.</LI>
1975     <LI>G4VVisCommand: added static G4SceneTreeItem
1976         <TT>fExistingSceneTree</TT>, used for remembering scene tree of
1977         previous viewer.</LI>
1978     <LI>G4VisCommandsSceneHandler: if there is an existing viewer, store scene

1987     <LI>G4VisCommandsSceneAdd, G4VisCommandSceneAddText2D: improved guidance and
1988         description.</LI>
1989     <LI>In G4VisCommandsTouchable, introduced UI command
1990         <TT>/vis/touchable/twinkle</TT>.</LI>

1992         Functionality now delegated to G4ViewParameters.</LI>

2011         touchables by depth of the geometry tree. Used in G4VViewer when
2012         deciding whether to expand the scene tree.

2225         <LI>New example demonstrating an application of Geant4 in space

2231             SPIE, 2018.
2232             The main purpose of the simulation is the estimation of the induced
