0213 <UL>
0214 <LI>It is now possible to introduce gaps between slices in divisions,
0215     by making use of a new specialised physical-volume type,
0216     <TT>G4ReplicatedSlice</TT> for defining the divided daughter volumes.</LI>
0217 <LI>In regular voxelised geometries, the restriction for voxels to completely
0218     fill the envelope container is now relaxed. It is now allowed to define
0219     envelopes of different types other than box for regular geometries,
0220     by making use of a new parameterisation helper class
0221     <TT>G4PartialPhantomParameterisation</TT>.</LI>
0222 <LI>A new specific shape, <TT>G4GenericTrap</TT>, is now implemented.
0223     This new solid represents an arbitrary trapezoid with up to 8 vertices
0224     standing on two parallel planes perpendicular to the <TT>Z</TT> axis.</LI>

0236 <LI>Cylindrical scoring mesh is now fully released.</LI>
0237 <LI>Most of primitive scorers now take their default units, and units may
0238     by altered by their UI commands. These units are used for drawing and

0244 <LI>New model <TT>G4ICRU73QOModel</TT> is available 
0245     for low-energy ionisation of negative-charge projectiles
0246     (including anti-ions); it is  based on ICRU'73 data for oscillator strengths;
0247     this model is the default for negative-charge particles in <TT>G4hIonisation</TT> process class.</LI> 
0248 <LI>Improved modeling of fluctuations in energy deposition, relevant for 
0249     deposit in gasses and silicon. Increases stability when step size changes.</LI> 
0250 <LI>New model of single scattering and NIEL for ions
0251     <TT>G4IonCoulombScatteringModel</TT> is available; the model is applicable 
0252     from <TT>50 keV</TT> to <TT>100 TeV</TT>.</LI> 
0253 <LI>New ionisation models <TT>G4BraggIonGasModel</TT>,
0254     <TT>G4BetheBlochIonGasModel</TT> are available for simulation of ion
0255     transport in low density media, e.g. in vacuum.  
0256     The ion charge of a particle is not changed by these models.</LI> 
0257 <LI>The default angular distribution of gamma in the Bremsstrahlung process
0258     can be substituted by alternative model in physics-list.</LI> 
0259 <LI>Fluorescence and Auger electron production can be activated via UI commands,
0260     using the new models <TT>G4PEEffectFluoModel</TT> and <TT>G4KleinNishinaModel</TT>.</LI> 
0261 <LI>Disabled usage of minimum energy threshold per model. As a result the
0262     production threshold is defined only by range (converted to energy in each 
0263     material). It remains constrained by the minimum limit defined in 'cut' category.
0264     This change is necessary to allow the full set of combinations of models

0270 <LI>Photon Livermore models:
0271     first implementation of pair production in the electric field of the
0272     electron. The <TT>G4BoldyshevTripletModel</TT> should be used in
0273     conjunction with the <TT>G4LivermoreNuclearGammaConversionModel</TT>
0274     model (using <TT>G4MultiModel</TT>) in order not to account twice
0275     for the pair production cross section in the electron field.</LI>

0282     PhotoElectric and Rayleigh). Upgrades of Penelope from version 2001 to
0283     version 2008, named as <TT>G4Penelope08xxxxModel</TT>. To be considered
0284     as beta.</LI>
0285 <LI>For all low energy EM models: no customized production cuts are allowed
0286     anymore for fluorescence/Auger.
0287     Main cuts from the <TT>G4ProductionCutsTable</TT> are always used, for

0307 <UL>
0308 <LI>Hadronic interfaces now require integer Z and A arguments.  Elements or
0309     materials with effective or average values of Z and A are no longer 
0310     allowed.</LI>
0311 <LI>Quark exchange, Reggeon cascade and nuclear destruction parameters in the FTF 
0312     model were tuned.   Tuning of the nuclear destruction parameters was based on
0313     HARP-CDP data. Low mass string fragmentation was improved.</LI>
0314 <LI>The Bertini cascade model was re-written to employ more code re-use, improve
0315     memory management, and provide better energy/momentum conservation.  Angular 
0316     distributions of the two-body final states of hadron-nucleon interactions were 
0317     redone and improved.  
0318     An optional interface to the G4Precompound model (and the associated 
0319     de-excitation processes) is now available;  this is an alternative to the 
0320     dedicated de-excitation which has been used until now.</LI> 
0321 <LI>Anti-baryon-nucleon elastic scattering was added to the CHIPS model.</LI>
0322 <LI>Fermi breakup was extended to include fragments with <TT>1 < A < 5 </TT>.
0323     Several improvements were made to bring the model closer to the original
0324     one of Botvina.  Use hybrid of Fermi breakup and GEM models for
0325     <TT>A < 20</TT>.  Several other improvements were made to the evaporation
0326     models.  A README file was added explaining the photo-evaporation data
0327     files.</LI>
0328 <LI>New, fast models and cross sections for neutron elastic, inelastic and capture
0329     are now available: G4NeutronElasticXS, G4NeutronInelasticXS and 
0330     G4NeutronCaptureXS. </LI>
0331 <LI>An isomer decay table was added to extend the number of existing isomers in the 
0332     radioactive decay model.  All of them will be decayed by isomeric transition
0333     (IT).  A README file was added to explain the radioactive decay data files. </LI>
0334 <LI>RQMD (relativistic quantum molecular dynamics) code was enabled in the QMD
0335     model to allow treatment of higher collision energies.</LI>
0336 <LI>A new model, <TT>G4NuclNuclDiffuseElastic</TT> is now available for 
0337     nucleus-nucleus elastic scattering.</LI>
0338 <LI>A new class <TT>G4ComponentAntiNuclNuclearXS</TT> provides
0339     the total elastic and inelastic cross sections of anti-nucleon
0340     and anti-nucleus interactions with nuclei.
0341     These were calculated using the Glauber approach.</LI>
0342 <LI>All hadronic processes now check to see if the cross section has become negative
0343     at the end of a step, before invoking the model.</LI>
0344 <LI>Checking of Energy/momentum conservation is available in the hadronic
0345     process class.  Methods can set the theshold level for reporting 
0346     and the verbosity of the output.</LI>

0427 <H2>7. Compilation Warnings</H2>
0428 
0429 There may be a few compilation warnings on some platforms.
0430 We do not believe that any of these lead to incorrect run-time behaviour.

0440 The following message may be written to standard output at the end of a program:
0441 <PRE>
0442     G4Transportation: Statistics for looping particles 
0443        Sum of energy of loopers killed: 
0444        Max energy of loopers killed: 
0445 </PRE>
0446 It provides the total energy (in <TT>MeV</TT>) of tracks  killed due to
0447 excessive number of steps ('looping') during the simulation, and the maximum
0448 energy of such a track. Such behaviour can be due to looping in magnetic fields
0449 or being abandoned due to being stuck at geometrical boundaries.
0450 <P></P>
0451 In case either of these reported energies is significant, we recommend
0452 increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
0453 each track killed. A user can change the threshold energy above which particles
0454 are killed more reluctantly (only after significant additional effort) using
0455 the method <TT>SetThresholdImportantEnergy()</TT> of <TT>G4Transportation</TT>.
0456 The default value is <TT>100 MeV</TT>.

1733 <LI><B>Management</B>
1734     <UL>
1735     <LI>Added new <TT>/vis/open</TT> command for OpenGL viewers,
1736         <TT>/vis/open OGL</TT>.
1737         This new form allows the same macro to be used whether one is on
1738         Linux or Windows (calling OGLSX on Linux and OGLSWin32 on Windows).
1739         When the application has been built with Qt, it will use the Qt form
1740         of OpenGL; when built with Motif, it will use the Motif form of OpenGL.
1741         Also added options OGLI and OGLS to force Immediate or Stored modes.
1742         The user is still free to use the older, specific viewer names, such
1743         as OGLIX, but the simple form, OGL, will give the most portable macros.</LI>
1744     <LI>Added new <TT>/vis/open</TT> command for OpenInventor, <TT>/vis/open OI</TT>.
1745         This new form allows the same macro to be used whether one is on Linux
1746         or Windows (calling OIX on Linux and OIWin32 on Windows).</LI>
1747     <LI>Added <TT>/vis/scene/add/digis</TT> and <TT>/vis/filtering/digi</TT>
1748         commands, analogous to the already-existing commands
1749         <TT>/vis/scene/add/hits</TT> and <TT>/vis/filtering/hits</TT>.
1750         As with hits, it remains the user's responsibility to provide the
1751         digitisation classes.
1752         Added method <TT>AddCompound(const G4VDigi&)</TT> to drivers.</LI>
1753     <LI>Introduced DispatchToModel without <TT>i_mode</TT>. The archaic form
1754         <TT>G4VTrajectory::DrawTrajectory(i_mode)</TT> is replaced by the
1755         newer form, <TT>G4VTrajectory::DrawTrajectory()</TT>. <TT>i_mode</TT>
1756         used to be a parameter to control whether the trajectory was drawn as
1757         a line, a line plus step points, or only step points:
1758         <UL>
1759         <LI>'i_mode > 0' meant draw lines and points, size of points in
1760                      'pixels = abs(i_mode)/1000'</LI>
1761         <LI>'i_mode = 0' meant draw only lines</LI>
1762         <LI>'i_mode < 0' meant draw only points, size of points in
1763                      'pixels = abs(i_mode)/1000'</LI>
1764         </UL>
1765         Since release 8.1, better control has been available from the command
1766         <TT>/vis/modeling/trajectories</TT>. Since release 5.0, <TT>i_mode</TT>
1767         less than 1000 has in fact drawn no points and <TT>i_mode</TT> of 1000
1768         has drawn points that were so small (a single pixel wide) that they
1769         were overshadowed by the trajectory itself except at endpoints of the
1770         trajectory or where the trajectory made a sharp change of direction.
1771         Use of <TT>i_mode</TT> is now trapped and a warning gets printed.</LI>
