0171 <B>General</B>
0172 <UL>
0173 <LI>Full event reproducibility is  provided in simulations with most physics
0174     lists; this  allows  to restart a simulation from an intermediate event
0175     and obtain exactly the same results, if the user specifies or restores
0176     the status of the pseudo random generator  at the beginning of the event.
0177     This strict event reproducibility is achieved in all physics models, with
0178     two exceptions:
0179     CHIPS stopping and neutron HP. This means that event reproducibility is
0180     valid for the  majority of the physics lists, including FTFP_BERT,
0181     QGSP_BERT and QGSP_FTFP_BERT.</LI>
0182 </UL>
0183
0184 <B>Geometry</B>
0185 <UL>
0186 <LI>A new optimized implementation of G4TessellatedSolid  provides
0187     substantial CPU performance boost and reduced memory
0188     footprint. Scaling of CPU time with increased complexity (number of facets)
0189     of the shapes being defined or imported.</LI>
0190 </UL>
0191
0192 <B>Materials</B>
0193 <UL>
0194 <LI>For all elements, a vector of G4Isotopes is always created using abundance
0195     values from NIST (in previous Geant4 versions, the vector of isotopes was
0196     created only for NIST materials). As a result it is no longer needed to
0197     define natural composition of isotopes in the user code.</LI>
0198 </UL>
0199
0200 <B>Electromagnetic physics</B>
0201 <UL>
0202 <LI>WentzelVI multiple scattering model is used by default in all EM physics
0203     lists. For electrons and positrons the WentzelVI model is used only above
0204     100 MeV.
0205     This was done to provide more accurate simulation both small and large
0206     angles of high energy charged particles.</LI>
0207 <LI>Sampling of multiple scattering  is performed AlongStep, before the
0208     sampling of energy loss (previously multiple scattering was sampled
0209     PostStep, after the energy loss). The physics performance is unchanged.</LI>
0210 <LI>New processes for microdosimetry in Silicon for electrons, protons and
0211     ions (G4MuElecElastic, G4MuElecInelastic) and corresponding models
0212     (G4MuElecElasticModel, G4MuElecInelasticModel).</LI>
0213 <LI>New Compton scattering model (G4LowEPComptonModel) along with specific
0214     Physics builder (G4EmLowEPPhysics).</LI>
0215 <LI>New builder selects the most accurate models now available for each
0216     process; this  is G4EmStandardPhysics_option4. Models from both standard
0217     and low-energy options are used.</LI>
0218 </UL>
0219
0220 <B>Hadronic physics</B>
0221 <UL>
0222 <LI>Hadronic processes now trigger re-sampling of the interaction if
0223     energy/momentum non-conservation limits are exceeded. A warning message
0224     is printed if this occurs.</LI>
0225 <LI>New hadron stopping models G4PiMinusAbsorptionBertini,
0226     G4KaonMinusAbsorptionBertini, G4SigmaMinusAbsorptionBertini,
0227     G4AntiProtonAbsorptionFritiof, and G4AntiSigmaPlusAbsorptionFritiof
0228     are added. </LI>
0229 <LI>New total cross section sets based on SAID data-base are added.
0230     (They are used for proton, neutron and pion cross-sections on hydrogen
0231     in majority of physics lists.)</LI>
0232 <LI>A new option in the nuclear de-excitation module allows
0233     to ignore Doppler broadening for long lived meta-stable isotopes and
0234     provide instead decay at rest. This new feature is activated by the
0235     environment variable
0236   <IT>G4AddTimeLimitToPhotonEvaporation</IT>
0237   . If
0238     this environment variable is set the momentum balance of the
0239     de-excitation is broken and energy balance is respected.</LI>
0240 <LI>A new electro-nuclear interaction model, G4ElectroVDNuclearModel,
0241     was created. It is based on the CHIPS total cross sections, with final
0242     state modeling using the Bertini cascade and FTFP.</LI>
0243 <LI>The INCL cascade model (INCL++) was updated and can now handle
0244     heavy-ion collisions.</LI>
0245 <LI>HTML files describing hadronic processes, models and cross-sections can
0246     be printed by invoking the ProcessDescription(), ModelDescription()
0247     and CrossSectionDescription() methods, respectively.</LI>
0248 </UL>
0249
0250 <B>Physics Lists</B>
0251 <UL>
0252 <LI>The model of multiple scattering for electrons and positrons is changed
0253     in all physics lists for HEP applications. Introduced the WentzelVI
0254     model for multiple scattering of e+ and e- above 100 MeV. Below 100 MeV
0255     the Urban95 model is used in the main physics lists (whereas Urban93
0256     is used in EMV or EMX).</LI>
0257 <LI>Relativistic gamma conversion model in used in all physics
0258     constructors above 80 GeV.</LI>
0259 <LI>New EM physics constructor G4EmStandardPhysics_option4  selects the
0260     most accurate models for each EM process. It  combines models from
0261     standard and low-energy sub-packages.</LI>
0262 <LI>New model for lepton-nuclear interactions using Bertini and
0263     Fritiof/Pre-compound has been introduced in most physics list.
0264     Only LHEP- and CHIPS-based physics lists  still use the
0265     (deprecated) CHIPS model for handling lepton-nuclear interactions.</LI>
0266 <LI>Introduced Bertini model for
0267     nuclear capture at rest of pi-, K-, Sigma-, Xi- and Omega- in most
0268     physics lists.
0269     Also use Fritiof/Pre-compound model for anti-proton, anti-Sigma+
0270     and light anti-nucleus capture at rest in the same physics lists.
0271     Only LHEP- and CHIPS-based physics lists are still using the
0272     (deprecated) CHIPS model for handling nuclear capture at rest.</LI>
0273 <LI>CHIPS elastic and inelastic cross-sections for protons, neutrons, pions,
0274     kaons, hyperons and anti-baryons have been extracted and moved to the
0275     default module. They can now be selected individually for use in physics
0276     lists.</LI>
0277 <LI>Barashenkov-Glauber-Gribov nucleon-nucleus inelastic cross sections
0278     are now used in most physics lists instead of Axen-Wellisch
0279     proton-nucleus and Laidlaw-Wellisch neutron-nucleus inelastic
0280     cross sections.</LI>
0281 <LI>Glauber-Gribov nucleus-nucleus inelastic cross sections are now used
0282     in most physics lists instead of Shen (which in turn replaced Tripathi)
0283     cross sections.</LI>
0284 <LI>The new physics list FTFP_BERT_HP has been created: it is similar to
0285     FTFP_BERT, but using HP for low-energy neutrons.</LI>
0286 <LI>Four new physics lists have been created: QGSP_BERT_95,
0287     QGSP_FTFP_BERT_95, QGSP_BERT_95XS and QGSP_FTFP_BERT_95XS.
0288     The "95" variants have the same physics models and cross sections
0289     as QGSP_BERT and QGSP_FTFP_BERT, respectively, in Geant4 version 9.5.
0290     The "95XS" variants have the same cross sections as QGSP_BERT and
0291     QGSP_FTFP_BERT, respectively, in Geant4 version 9.5, whereas the
0292     physics models are the same as in Geant4 version 9.6.
0293     These physics lists, which have been created for "backward compatibility"
0294     with the production physics lists used by the experiments, are
0295     deprecated and will be removed in Geant4 10.
0296     FTFP_BERT remains the recommended physics list for high-energy
0297     applications.</LI>

0307     modeling.</LI>
0308 <LI>/vis/viewer/save, copyViewFrom - new commands to save view parameters
0309     and copy them from one view to another.</LI>
0310 <LI>Improved OpenGL rendering speed through major re-design of scene and
0311     transient processing. Use new command /vis/ogl/set/eventsDrawInterval
0312     to get even more speed when accumulating multiple events.</LI>
0313 <LI>/vis/scene/add/userAction now supports multiple user vis actions.
0314     Where previously one could only have a single user vis action, one can
0315     now register any number of such actions. Each action gets a specific name,
0316     and each can be assigned to any selected scene.</LI>
0317 <LI>Added Event ID to trajectory attributes so that in scenes that contain
0318     more than one event, one can tell which trajectory came from which event.</LI>
0319 <LI>Improved Qt interface and viewer.</LI>
0320 <LI>Improved handling of text.</LI>
0321 <LI>Added new OpenInventor option: /vis/open OIXE (in addition to the
0322     previous option, /vis/open OIX). Provides many new capabilities such
0323     as ability to set viewpoints and to fly along a trajectory path.
0324     This is an excellent viewer selection for accelerator studies or other
0325     situations in which it can otherwise be difficult to set appropriate
0326     views.</LI>

1077 <UL>
1078 <LI>Removed obsolete "incl" module for INCL model; now replaced by INCL++.</LI>
1079 <LI>Renamed 'photonlepton_hadron/muon_nuclear' model to 'lepto_nuclear'</LI>
1080 <LI>Fixed cases of variable shadowing and Coverity defects.</LI>
1081 <LI>Explicitly use inclusion of headers for system of units and physical
1082     constants.</LI>
1083 <LI><B>Cross sections</B>
1084     <UL>
1085     <LI>G4CrossSectionDataStore: introduced cash for material and element
1086         cross-sections in order to save CPU; cross-section for material
1087         is not recomputed if material, primary particle and kinetic
1088         energy are the same; cross-section for element is not recomputed
1089         if material, element, primary particle and kinetic energy are the
1090         same; G4Nucleus is updated using new method SetIsotope().
1091         Take into account that all elements should have isotopes.</LI>
1092     <LI>G4VCrossSectionDataSet: added virtual method SelectIsotope() which is
1093         used for element wise cross-sections, allowing for the data-set to use
1094         isotope wise cross-sections when isotope is selected; by default the
1095         old method is used based on isotope abundance; no change of results
1096         expected.</LI>
1097     <LI>G4HadronNucleonXsc: updated p,n,pi-,pi+ cross-sections on p,n.
1098         Added new method GetCoulombBarrier().</LI>
1099     <LI>G4GGNuclNuclCrossSection, G4GlauberGribovCrossSection: updated to get
1100         total and inelastic cross-sections from G4HadronNucleonXsc.</LI>
1101     <LI>G4BGGNucleonInelastic, G4BGGNucleonElastic: use SAID data for
1102         scattering
1103         off hydrogen below 1.3 GeV for neutrons and below 2 GeV for protons.
1104         G4BGGPionInelastic, G4BGGPionElastic: use SAID data for scattering
1105         off hydrogen below 2.6 GeV.</LI>
1106     <LI>G4GGNuclNuclCrossSection: updated to get nucleus radii of light
1107         elements p, d, t, He3, He4, Li7 and Be9.
1108         Fixed condition and setting minimum kinetic energy in to 0.</LI>
1109     <LI>New classes G4ComponentGGNuclNuclXsc based on G4GGNuclNuclCrossSection
1110         (Glauber-Gribov for ion-ion cross section) and G4ComponentBarNucleonNucleusXsc
1111         based on G4NucleonNuclearCrossSection (Barashenkov cross section); implemented
1112         component interface.</LI>
1113     <LI>Added elastic and inelastic cross-sections extracted from CHIPS.
1114         Make GetExchangeT() method public to be used in coherent_elastic.</LI>
1115     <LI>Extended functionality of G4CrossSectionDataSetRegistry to allow
1116         sharing of cross-sections sets. Make exception in method
1117         GetCrossSectionDataSet() optional.</LI>
1118     <LI>New class G4ComponentSAIDTotalXS for SAID cross-sections.</LI>
1119     <LI>Use new cross-sections factory for CHIPS elastic and inelastic
1120         cross-sections. Removed unnecessary statics in CHIPS cross-sections
1121         and fixed case of double-deletion.
1122         Removed G4ChipsBaseXS class.</LI>
1123     <LI>G4NeutronCaptureXS: use G4ElementData for isotope x-sections.
1124         Implemented isotope selection based on isotope cross-section.</LI>
1125     <LI>G4ComponentSAIDTotalXS: fixed cross section computation.</LI>
1126     <LI>Added factory mechanism for G4GlauberGribovCrossSection,
1127         G4NucleonNuclearCrossSection and G4GGNuclNuclCrossSection.</LI>
1128     <LI>Make two methods in CHIPS cross-sections public for the use in
1129         quasi-elastic module.</LI>
1130     <LI>New data-set G4SAIDDATA1.1 controlled by path variable G4SAIDXSDATA
1131         is now required.</LI>
1132     </UL></LI>
1133 <LI><B>Management</B>
1134     <UL>
1135     <LI>Added method to address energy non-conservation; if check finds
1136         violation of energy conservation, re-sample the interaction.
1137         <UL>
1138         <LI>Limits are set in
1139             G4HadronicInteraction, and may be overridden per model; LEP and HEP
1140             override defaults, as these do not include the recoil nucleus in the
1141             final state.</LI>
1142         <LI>Failure of E/p conservation is signalled only if both checks,
1143             absolute and relative, fail. Thus violations which  either a) are
1144             just smaller in absolute value than the value threshold or b) are
1145             just a smaller fraction than the threshold fraction (but not both)
1146             will not fail.</LI>
1147         <LI>Added check for momentum conservation, reusing limits for energy.</LI>
1148         <LI>Added check for charge and baryon number conservation; active only
1149             if limit is less than DBL_MAX.</LI>
1150         </UL>
1151     </LI>

1153         <UL>
1154         <LI>Moved some data members to protected to be used in
1155             derived classes; removed unused code. </LI>
1156         <LI>Changed logic of definition of time for secondary particles
1157             inside method FillResults().</LI>
1158         <LI>Moved to use method ResetNumberOfInteractionLengthLeft() and
1159             GetTotalNumberOfInteractionLengthTraversed() from G4VProcess.</LI>
1160         <LI>Dropped the check cross-section in PostStepDoIt() in the case of
1161             neutral particles, in order to improve CPU performance.
1162             Now check only for charged particles.</LI>
1163         <LI>Improved quick check and full check for case of electro-nuclear.
1164             Copes with case that both primary survives and secondaries are
1165             created.</LI>
1166         <LI>Fixed problem of flushing stdout/stderr for energy checking
1167             printout.</LI>
1168         <LI>Removed GetTargetDefinition(); instead added GetTargetIsotope().</LI>
1169         <LI>Added catch of G4HadronicException inside BuildPhysicsTable()
1170             method.</LI>
1171         <LI>Added full printout about hadronic exception inside G4Exception
1172             body; addressing problem report
1173             <A HREF="http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1377">#1377</A>.</LI>

1177         GetTargetDefinition() and GetCrossSectionPerVolume().
1178         Added e+ and mu+ to level-1 reporting.</LI>
1179     <LI>Added printing of model descriptions to html files.</LI>
1180     <LI>Moved isotope production infrastructure from process to model level;
1181         now done only for LEP models. Updated G4HadronicProcess accordingly.</LI>
1182     <LI>G4IsoParticleChange: moved to models/management module.</LI>
1183     <LI>G4HadronicProcessType: added 'fLeptonAtRest'.</LI>
1184     <LI><U>Models</U>:
1185         <UL>
1186         <LI>Moved G4InelasticInteraction class to 'low_energy' model.</LI>
1187         <LI>G4IsoParticleChange: moved from main 'management' module.</LI>
1188         <LI>G4VIsotopeProduction: replace G4Track argument in GetIsotope() with
1189             G4HadProjectile.</LI>
1190         <LI>G4VHighEnergyGenerator: added virtual method
1191             PartonStringModelDescription().</LI>
1192         <LI>G4VIntraNuclearTransportModel, G4VPreCompoundModel: cleanup for
1193             object construction/deletion.</LI>
1194         <LI>Provide method and default values for checking of "catastrophic"
1195             energy non-conservation. Current default is a deviation larger than
1196             150 MeV and at least 10% of the kinetic energy of the primary.
1197             Set default limit for energy non-conservation to 5 GeV;</LI>
1198         <LI>Added G4VIntraNuclearTransportModel::Description() method, printing
1199             a descriptive message before throwing a G4Exception.</LI>
1200         <LI>Modified G4VHighEnergyGenerator: added ModelDescripion() to interface;
1201             made private the copy-constructor and the =,  ==, and != operators, which are not
1202             implemented.</LI>
1203         <LI>G4VIntraNuclearTransportModel: added PropagateModelDescription()
1204             method.</LI>
1205         <LI>G4HadronicInteractionRegistry: added method FindModel() allowing to

1209 <LI><B>Processes</B>
1210     <UL>
1211     <LI>G4*HadronElasticProcess: replaced use of "aParticleChange" with
1212         "theTotalResult", and drop callback to
1213         G4VDiscreteProcess::PostStepDoIt().</LI>
1214     <LI>G4HadronElasticProcess: use cut for recoil as energy threshold to
1215         produce recoil ion. Added deprecation warning for obsolete method.
1216     <LI>Marked as obsolete G4WHadronElasticProcess class.</LI>
1217     </UL></LI>
1218 <LI><B>Stopping</B>
1219     <UL>
1220     <LI>Removed class G4FTFCaptureAtRest and replaced with the new classes
1221         G4HadronicAbsorptionFritiof, G4AntiProtonAbsorptionFritiof
1222         and G4AntiSigmaPlusAbsorptionFritiof.
1223         Modified initialisation of de-excitation; fixed
1224         potential cases of double deletion of objects; added registration
1225         in G4HadronicProcessStore and added sub-type definition.
1226         Included annihilation of anti_sigma+.</LI>
1227     <LI>Added new classes G4MuonMinusBoundDecay, G4ElementSelector,
1228         G4EmCaptureCascade, G4MuMinusCapturePrecompound,
1229         G4HadronStoppingProcess, G4MuonMinusCapture, providing general
1230         stopping process.</LI>
1231     <LI>New class G4HadronicAbsorptionBertini inheriting from
1232         G4HadronStoppingProcess, registering Bertini as the model.
1233         G4PiMinusAbsorptionBertini as subclass of G4HadronicAbsorptionBertini,
1234         G4KaonMinusAbsorptionBertini and G4SigmaMinusAbsorptionBertini new
1235         subclasses of G4HadronicAbsorptionBertini.</LI>
1236     <LI>G4MuonMinusBoundDecay, G4StopElementSelector: added data
1237         for muon capture rate in Hydrogen and He4 from recent experimental
1238         data.</LI>
1239     <LI>G4HadronicAbsorptionBertini: drop list of "allowed" hadrons, so Bertini
1240         can take care of any negative hadron thrown at it.
1241         Use Bertini's IsApplicable() function to decide whether incident
1242         projectile is suitable for absorption or not.</LI>
1243     <LI>Flag deprecated classes in the 9.6 release, to be removed for next
1244         major release; added warnings to constructors. Stopping hadrons are
1245         now handled by Bertini and Fritiof models, and muon capture by the more
1246         complex process with atomic cascade effects.</LI>
1247     <LI>Added nuclear capture at rest of anti-nuclei with FTFP in
1248         G4HadronicAbsorptionFritiof.</LI>
1249     <LI>G4HadronicAbsorptionFritiof, G4MuMinusCapturePrecompound,
1250         G4MuMinusBoundDecay, G4EmCaptureCascade: fixed memory leak;
1251         reuse G4PreCompoundModel instead from the store of creation of
1252         a new one.</LI>
1253     <LI>G4HadronStoppingProcess: defined two argument constructor with defaults
1254         used G4HadronicProcessType in the constructor.</LI>
1255     <LI>Replaced replicated code blocks for deprecation messages with new
1256         G4HadronicDeprecate macro from 'utils' module.</LI>
1257     </UL></LI>
1258 <LI><B>Utility</B>
1259     <UL>
1260     <LI>G4HadProjectile: added methods SetGlobalTime(), SetBoundEnergy() and
1261         GetBoundEnergy() needed for general stopping process; always set time
1262         to zero at construction or initialisation, so hadronic interaction is
1263         starting from zero local time.
1264         Added Initialise() method allowing to update the projectile and not
1265         instantiate it for any new interaction. Inlined all get methods.
1266         Added protection to kinetic energy computation.</LI>
1267     <LI>G4Nucleus: added methods GetIsotope(), SetIsotope().</LI>

1275     </UL></LI>
1276 <LI><B>Binary Cascade</B>
1277     <UL>
1278     <LI>G4BinaryCascade: when propagating secondaries from HE model,
1279         do not modify initial energy for Fermi level.</LI>
1280     <LI>G4BinaryCascade, G4BinaryLightIonReaction and
1281         G4GeneratorPrecompoundInterface: reuse already instantiated
1282         pre-compound model, if existing.</LI>
1283     <LI>Added description in G4BinaryLightIonReaction.</LI>
1284     <LI>Fixed minor leak in G4GeneratorPrecompoundInterface.</LI>
1285     <LI>Code cleanup & splitting of long methods.
1286     <LI>Fix charge/baryon number violation for Propagate() interface in
1287         G4RKPropagtion. Added method to optionally check baryon/charge
1288         conservation. Added model descriptions also for Propagate().</LI>
1289     </UL></LI>
1290 <LI><B>Bertini Cascade</B>
1291     <UL>
1292     <LI>Developed and improved ability of Bertini cascade to handle
1293         photo-nuclear and elector-nuclear interactions and the interactions
1294         of stopping particles.</LI>
1295     <LI>G4CascadeInterface: check for no-interaction in retryInelasticProton(),
1296         both in return value and in debugging report.
1297         Added new function for dumping configuration.</LI>
1298     <LI>G4CascadeChannelTables: added "om*pro" and "om*neu" to LoadTables().</LI>
1299     <LI>G4CascadeCheckBalance: lower verbosity level for energy-conservation
1300         reports, change violation rules to allow relative OR absolute passing,
1301         consistent with new process-level checks.  Added reporting of
1302         strangeness conservation.</LI>
1303     <LI>G4CascadeCoalescence: fixed bug for clear at start of event of the list
1304         of clusters already considered; entries from previous events prevented
1305         formation of valid clusters. Also improved diagnostic messages.</LI>
1306     <LI>G4CascadeCollisionOutput: added calculations of net strangeness.</LI>
1307     <LI>G4CascadeKminusPChannel: modified two-body cross-section values in
1308         zero-energy bin, to reflect stopping data.</LI>
1309     <LI>G4CascadeOmegaMinusPChannel, G4CascadeOmegaMinusNChannel:  New classes
1310         containing partial cross-sections for omega- p and omega- n reactions.</LI>
1311     <LI>G4CascadeParameters: new singleton container class to hold and
1312         evaluate any developer-configured environment variables. Default
1313         values for parameters are provided. Three new flags are also
1314         defined: G4CASCADE_VERBOSE (pre-set verbosity in G4CascadeInterface
1315         constructor), G4CASCADE_USE_PRECOMPOUND (select use of
1316         PreCompoundModel in G4CascadeInterface constructor),
1317         G4NUCMODEL_USE_BEST (re-set all defaults for nuclear model with
1318         physical units).</LI>
1319     <LI>G4CascadeParamMessenger: new class to define UI macro commands for
1320         setting G4CascadeParameters (string) values, as an alternative to
1321         environment variables.</LI>
1322     <LI>G4CascadeParticle: added public accessor for cumulative path length.</LI>
1323     <LI>G4CascadePPChannel, G4CascadeNPChannel, G4CascadeNNChannel: new
1324         final-state tables implemented as subclass of templated base (rather
1325         than 'typedef'). Overrides findCrossSection() function to apply
1326         analytic (parametrized) function from Stepanov for projectiles below
1327         10 MeV, with maximum cross-section at zero-bin value.  Use
1328         Stepanov's cross section values up to 420 MeV.</LI>
1329     <LI>G4CascadeSigmaMinusPChannel: changed zero-bin cross-sections for
1330         Lambda-n and Sigma0-n, based on data from M. Goossens et al.
1331         measurements of Sigma- capture.</LI>
1332     <LI>Removed G4CascadeT1NNChannel class and split into separate pp, pn
1333         and nn files (see G4CascadePPChannel, etc.).
1334     <LI>G4Dineutron, G4Diproton, G4UnboundPN: added protection against warning
1335         messages issued from G4ParticleTable::Remove().</LI>
1336     <LI>G4ElementaryParticleCollider: added angular distributions for elastic
1337         and inelastic 2-body final states of gamma p and gamma n reactions.
1338         Allow photons to be absorbed via dibaryon (quasideuteron) excitation.
1339         In generateSCMfinalState(), defer "particles.resize()" action until
1340         after final-state properties have been validated. In case no final
1341         state can be generated, this ensures that the failure propagates
1342         back up the calling chain, instead of simply looping forever.</LI>
1343     <LI>G4ExitonConfiguration: added empty() function to test exciton state,
1344         reduced printout to single line.</LI>
1345     <LI>G4Fissioner: removed static in local vectors in method collide(), to
1346         ensure event reproducibility.</LI>
1347     <LI>G4IntraNucleiCascader: specify mass when decaying trapped particle.
1348         This fixes reproducibility violations when hyperons are forced to
1349         decay inside the nucleus.</LI>
1350     <LI>G4InuclNuclei: report non-empty exciton configuration in print().</LI>
1351     <LI>Added additional diagnostic messages in G4NonEquilibriumEvaporator and
1352         G4EquilibriumEvaporator.</LI>
1353     <LI>G4NucleiModel: New function isProjectile() identifies incident
1354         particle at start of cascade.  Return zero from getPotential() for
1355         photons in cascade.  Added binned spectrum for photons in
1356         absorptionCrossSection().  Added scale factor for gamma absorption.
1357         Allow photons to be absorbed via dibaryon (quasideuteron) excitation.
1358         Simplified and encapsulated path-length computations.</LI>
1359     <LI>G4PreCompoundDeexcitation: avoid double deletion of pre-compound
1360         model and excitation handler.</LI>
1361     </UL></LI>
1362 <LI><B>Chiral Invariant Phase Space (CHIPS)</B>
1363     <UL>
1364     <LI>New tuning for stopping in CHIPS. Added re-scattering to allow for
1365         wider energy resolution.</LI>
1366     <LI>Fixed charge non-conservation problem and memory leak in
1367         G4QFreeScattering.</LI>
1368     <LI>Bug fixes for E/M violation with (dE)^2+(dp)^2>.5 MeV^2.</LI>
1369     <LI>Split G4QInelastic into G4QInelastic and G4QNGamma classes for use
1370         with the CHIPS_HP physics-list.</LI>
1371     <LI>Fix to hadron elastic and inelastic interfaces to correct the use of
1372         the base class G4VCrossSectionDataSet.</LI>
1373     <LI>Fix for quasi-elastic duplication in G4QInelastic (for p & n).</LI>
1374     <LI>Fixed warning in G4QPDGCode.</LI>
1375     <LI>Added deprecation warning message to constructors for removal in next
1376         major release.</LI>
1377     </UL></LI>
1378 <LI><B>De-excitation</B>

1750     <LI>EM physics builders and options:
1751     <UL>
1752     <LI>In all EM builders use the same instances of the Bremsstrahlung and
1753         e+/e- pair production processes for each particle/antiparticle pair.
1754         As a result, mu+ and mu- share one instance of each process. Pi+
1755         and pi- share a different instance of each process.  The same occurs
1756         for K+ and K-, and for proton and antiproton.
1757         Expect reduction of memory required for physics tables and
1758         initialisation time for EM physics.</LI>
1759     <LI>In all EM builders use WentzelVI multiple scattering model for e+-
1760         above 100 MeV; build transport mean free path for He3 and He4, do not
1761         build for all other ions and heavy hadrons.</LI>
1762     <LI>New builder G4EmStandardPhysics_option, combining standard and
1763         low-energy physics configuration as best combination.
1764         Added "opt4" to G4PhysListFactory.</LI>
1765     <LI>Modified method of instantiation of multiple scattering: the same
1766         process instance is used by mu+ and mu-;
1767         Note: different instances are still used for  pi+, pi-, K+, K-, proton
1768         and antiprotons. Separate processes are needed to enable the different
1769         internal transport cross-section tables.
1770         For all others particles one (extra) process instance is used and no table
1771         is built.</LI>
1772     <LI>Use the WentzelVI model for e+ and e- above 100 MeV in all standard
1773         builders for HEP use cases (Opt0, Opt1, Opt2).  This is coupled with
1774         single Coulomb scattering using G4eCoulombScattering models.
1775         Below 100 MeV the G4UrbanMscModel95 model is retained.
1776         This addresses the issue of unphysical large angle scatters of GeV
1777         electrons reported by Atlas.</LI>

1838         for antiproton, anti-Sigma+ and light anti-nucleus capture at rest
1839         in the same physics lists.</LI>
1840     <LI>Added four new physics lists: QGSP_BERT_95, QGSP_BERT_95XS,
1841         QGSP_FTFP_BERT_95 and QGSP_FTFP_BERT_95XS.</LI>

1850         Only LHEP- and CHIPS-based physics lists keep using exactly the same
1851         physics as before, whereas all other physics lists migrate to the new
1852         default. Deprecated the physics lists that will be removed in next

1925     <LI>Improved commands:
1926         <UL>
1927         <LI>/vis/scene/add/axes - default size is now computed automatically,
1928             limit width to length/50.</LI>

1930         <LI>/vis/scene/add/scale - default size is now computed automatically.</LI>
1931         </UL></LI>
1932     <LI>Extended G4VisManager to support multiple user vis actions.
1933         Where previously one could only have a single user vis action, one can
1934         now register any number of such actions. Each action gets a specific
1935         name, and each can be assigned to any selected scenes.
1936         See the help system or user guide for details:
1937         /vis/scene/add/userAction.</LI>
1938     <LI>Added Event ID to trajectory attributes so that in scenes that contain
1939         more than one event, one can tell which trajectory came from which
1940         event.</LI>
1941     <LI>Removed creation date from EPS files (so that one can more easily use
1942         diff to tell that two files have the same graphics).</LI>
1943     <LI>Implemented 'BeginDraw/EndDraw' and 'BeginDraw2D/EndDraw2D'.
1944         This forces all thus-bracketed Draw messages to have the same
1945         transformation. If an attempt to change the transformation is detected,
1946         a fatal exception is raised.</LI>
1947     <LI>Migrated drivers to use G4VScenehandler::fObjectTransformation.</LI>

1955         unnecessary screen refreshing, incorrect buffer switching
1956         (necessitating extra refreshing), variable shadowing, etc.</LI>
1957     <LI>Removed #ifdef G4VIS... from header files.</LI>
1958     <LI>Protected against use of 2D primitives in viewers that can not handle
1959         these.</LI>
1960     <LI>Improved handling of parallel worlds (some worlds had been missing from redraws).</LI>
1961     <LI>Added SetBaseFullPVPath(). The base full path is the full path of the
1962         top physical volume (actually the full path of the mother of the top
1963         physical volume), so that even if a user issues
1964         '/vis/drawVolume sub-detector', the full path includes the base full
1965         path, i.e., the full path up to the world volume.</LI>
1966      <LI>G4ModelingParameters: added VisAttributesModifiers, enums and a nested
1967         class for communicating a modification to the vis attributes for a
1968         specific touchable defined by PVNameCopyNoPath, to be used by new
