<H2>3. Items for migration of the user code</H2>
Listed here is some relevant information on developments included in this
release, some of which may require migrations (mainly for users of advanced
Geant4 features) in order to upgrade from release 9.3 to release 9.4.
Note that for all users a full re-installation of libraries (or a full
recompilation) and a recompilation of user applications is required.
<P> </P>
<B>Standard Electromagnetic physics</B>
<P> </P>
<UL>
<LI>Changed default multiple scattering models to <TT>G4UrbanMscModel93</TT>
for electrons and positron, <TT>G4WentzelVIModel</TT> for muons.
<TT>G4UrbanMscModel90</TT> remains the choice for other particles.</LI>
<LI>Removed obsolete classes <TT>G4MultipleScattering, G4UrbanMscModel</TT> and
<TT>G4UrbanMscModel2</TT>. The use of multiple scattering processes
specialised by particle type (<TT>G4eMultipleScattering, G4hMultipleScattering</TT>
and <TT>G4MuMultipleScattering</TT>) is now mandatory.
</UL>
<P> </P>
<B>Low Energy Electromagnetic physics</B>
<P> </P>
<UL>
<LI>The Geant4-DNA <TT>G4DNAEmfietzoglouExcitationModel</TT> class for the modeling of
electron excitation in liquid water is obsolete and should be replaced
by the <TT>G4DNABornExcitationModel</TT> class.</LI>
</UL>
<P> </P>
<B>Persistency</B>
<P> </P>
<UL>
<LI>GDML: to better match the schema definition, a correction to the 'value'
type from <TT>double</TT> to <TT>string</TT> has been made for the
auxiliary-information returned by <TT>G4GDMLParser</TT>. This may require
related change in the user code, where the auxiliary information feature
is used.</LI>
</UL>
<P> </P>
<B>Physics Lists</B>
<P> </P>
<UL>
<LI>Previously obsolete physics lists have been deleted, for the detailed
list please see <a href="#lst-notes">below</a>.
<LI>Introduced new constructor for all builders with a common signature.
Previous constructors are kept for this release, but are declared obsolete.
They will be removed in a future release.
</LI>
</UL>
<P> </P>
<B>Visualization</B>
<P> </P>
<UL>
<LI>The visualization trajectory modeling command
<TT>/vis/modeling/trajectories/create/drawByParticleID</TT>
used to default all trajectories to grey, with the user having to
explicitly set any other color code. While the user can still set any
wished color code, the default has been improved to:
<TT>[e-/red; e+/blue; proton/cyan; gamma/green; neutron/yellow;
pi+,pi-,pi0/magenta; other/grey]</TT>.</LI>
<LI>In some examples, visualization that used to draw trajectories as simple
lines now also draws step points. Users who wish to disable step point
drawing can do so by commenting out a line in the visualization macro.</LI>
</UL>
<P> </P>
<B>Data Sets</B>
<P> </P>
This release introduces new data sets and also new versions.
Please see the corresponding details in
<A href="#data-notes">Section 10</A> of this document.

<!-- ============================================== -->
<H2>4. New Developments and Capabilities </H2>
<B>Geometry</B>
<UL>
<LI>It is now possible to introduce gaps between slices in divisions,
by making use of a new specialised physical-volume type,
<TT>G4ReplicatedSlice</TT> for defining the divided daughter volumes.</LI>
<LI>In regular voxelised geometries, the restriction for voxels to completely
fill the envelope container is now relaxed. It is now allowed to define
envelopes of different types other than box for regular geometries,
by making use of a new parameterisation helper class
<TT>G4PartialPhantomParameterisation</TT>.</LI>
<LI>A new specific shape, <TT>G4GenericTrap</TT>, is now implemented.
This new solid represents an arbitrary trapezoid with up to 8 vertices
standing on two parallel planes perpendicular to the <TT>Z</TT> axis.</LI>
</UL>
<B>Detector description persistency</B>
<UL>
<LI>Introduced new UI commands from the GDML parser to allow for importing and
exporting GDML files through macros or interactively, supporting all
various options provided by the parser.</LI>
</UL>
<B>Digitization &amp; Hits</B>
<UL>
<LI>Cylindrical scoring mesh is now fully released.</LI>
<LI>Most of primitive scorers now take their default units, and units may
by altered by their UI commands. These units are used for drawing and
dumping the scores.</LI>
</UL>
<B>Standard Electromagnetic physics</B>
<UL>
<LI>New model <TT>G4ICRU73QOModel</TT> is available
for low-energy ionisation of negative-charge projectiles
(including anti-ions); it is based on ICRU'73 data for oscillator strengths;
this model is the default for negative-charge particles in <TT>G4hIonisation</TT> process class.</LI>
<LI>Improved modeling of fluctuations in energy deposition, relevant for
deposit in gasses and silicon. Increases stability when step size changes.</LI>
<LI>New model of single scattering and NIEL for ions
<TT>G4IonCoulombScatteringModel</TT> is available; the model is applicable
from <TT>50 keV</TT> to <TT>100 TeV</TT>.</LI>
<LI>New ionisation models <TT>G4BraggIonGasModel</TT>,
<TT>G4BetheBlochIonGasModel</TT> are available for simulation of ion
transport in low density media, e.g. in vacuum.
The ion charge of a particle is not changed by these models.</LI>
<LI>The default angular distribution of gamma in the Bremsstrahlung process
can be substituted by alternative model in physics-list.</LI>
<LI>Fluorescence and Auger electron production can be activated via UI commands,
using the new models <TT>G4PEEffectFluoModel</TT> and <TT>G4KleinNishinaModel</TT>.</LI>
<LI>Disabled usage of minimum energy threshold per model. As a result the
production threshold is defined only by range (converted to energy in each
material). It remains constrained by the minimum limit defined in 'cut' category.
This change is necessary to allow the full set of combinations of models
in a process.</LI>
</UL>
<B>Low Energy Electromagnetic physics</B>
<UL>
<LI>Photon Livermore models:
first implementation of pair production in the electric field of the
electron. The <TT>G4BoldyshevTripletModel</TT> should be used in
conjunction with the <TT>G4LivermoreNuclearGammaConversionModel</TT>
model (using <TT>G4MultiModel</TT>) in order not to account twice
for the pair production cross section in the electron field.</LI>
<LI>Electron Livermore models:
<TT>G4LivermoreIonisationModel</TT> is able to generate fluorescence
along the step. Addressing problem report
<A HREF="http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1141">#1141</A>.</LI>
<LI>Penelope models:
added four new models (gamma ray models: Compton, GammaConversion,
PhotoElectric and Rayleigh). Upgrades of Penelope from version 2001 to
version 2008, named as <TT>G4Penelope08xxxxModel</TT>. To be considered
as beta.</LI>
<LI>For all low energy EM models: no customized production cuts are allowed
anymore for fluorescence/Auger.
Main cuts from the <TT>G4ProductionCutsTable</TT> are always used, for
consistency.</LI>
<LI>Geant4-DNA (in liquid water):
<UL>
<LI>New process and model classes for electron attachment and vibrational
excitation.</LI>
<LI>New electronic excitation model for electrons.</LI>
<LI>Extended very low energy coverage of Champion's electron elastic
scattering.</LI>
<LI>New excitation model for neutral hydrogen.</LI>
<LI>Preliminary new ionization models for <TT>C, N, O</TT> and <TT>Fe</TT>.
To be considered as beta.</LI>
<LI>Multi-scale combination of Geant4-DNA discrete processes with Standard
or low energy EM physics processes adopting the unified software
approach of both EM physics sub-categories (see the
<TT>microdosimetry</TT> advanced example for illustration).</LI>
</UL></LI>
</UL>
<B>Hadronic physics</B>
<UL>
<LI>Hadronic interfaces now require integer Z and A arguments. Elements or
materials with effective or average values of Z and A are no longer
allowed.</LI>
<LI>Quark exchange, Reggeon cascade and nuclear destruction parameters in the FTF
model were tuned. Tuning of the nuclear destruction parameters was based on
HARP-CDP data. Low mass string fragmentation was improved.</LI>
<LI>The Bertini cascade model was re-written to employ more code re-use, improve
memory management, and provide better energy/momentum conservation. Angular
distributions of the two-body final states of hadron-nucleon interactions were
redone and improved.
An optional interface to the G4Precompound model (and the associated
de-excitation processes) is now available; this is an alternative to the
dedicated de-excitation which has been used until now.</LI>
<LI>Anti-baryon-nucleon elastic scattering was added to the CHIPS model.</LI>
<LI>Fermi breakup was extended to include fragments with <TT>1 < A < 5 </TT>.
Several improvements were made to bring the model closer to the original
one of Botvina. Use hybrid of Fermi breakup and GEM models for
<TT>A < 20</TT>. Several other improvements were made to the evaporation
models. A README file was added explaining the photo-evaporation data
files.</LI>
<LI>New, fast models and cross sections for neutron elastic, inelastic and capture
are now available: G4NeutronElasticXS, G4NeutronInelasticXS and
G4NeutronCaptureXS. </LI>
<LI>An isomer decay table was added to extend the number of existing isomers in the
radioactive decay model. All of them will be decayed by isomeric transition
(IT). A README file was added to explain the radioactive decay data files. </LI>
<LI>RQMD (relativistic quantum molecular dynamics) code was enabled in the QMD
model to allow treatment of higher collision energies.</LI>
<LI>A new model, <TT>G4NuclNuclDiffuseElastic</TT> is now available for
nucleus-nucleus elastic scattering.</LI>
<LI>A new class <TT>G4ComponentAntiNuclNuclearXS</TT> provides
the total elastic and inelastic cross sections of anti-nucleon
and anti-nucleus interactions with nuclei.
These were calculated using the Glauber approach.</LI>
<LI>All hadronic processes now check to see if the cross section has become negative
at the end of a step, before invoking the model.</LI>
<LI>Checking of Energy/momentum conservation is available in the hadronic
process class. Methods can set the theshold level for reporting
and the verbosity of the output.</LI>
</UL>
<P> </P>
<B>Physics Lists</B>
<UL>
<LI>New physics lists QGSP_BERT_CHIPS and Shielding, details are described <a
href="#lst-notes">below</a>.
<LI>Improved inelastic hadronic cross section at high energies, above 90 GeV,
in all QGS.. and FTF.. lists.
<LI>Improved cross sections for Kaon, and all "misc" particles, including
anti-proton, anti-neutron, and hyperons in FTFP_BERT, QGSP_FTFP_BERT, and the
two new physics lists QGSP_BERT_CHIPS and Shielding.
<LI>Use <TT>G4UrbanMscModel93</TT> by default for e+,e- in all EM physics
builders except <TT>G4EmLivermorePhysics</TT> and <TT>G4EmPenelopePhysics</TT>
where new <TT>G4GoudsmitSaundersonMscModel</TT> is used.</LI>
<LI><TT>G4WentzelVIModel93</TT> and <TT>G4CoulombScattering</TT> are
used by default for mu+,mu- in all builders.</TT>
<LI>In <TT>G4EmStandardPhysics_option2</TT> for small angle multiple scattering
<TT>G4WentzelVIModel93</TT> is used for protons, pions, and kaons;
for angular distribution of bremmstrahlung gamma <TT>G4GeneratorBS</TT>
is applied.</LI>
<LI>Improved <TT>G4EmConfigurator</TT> class, to define alternative models by particle
type, energy range, and detector region.
Can be used to choose configuration EM models before or after the EM physics
has been instantiated.</LI>

<H2>5. Expected effects on physics and performance</H2>
<B>Standard Electromagnetic physics and cuts</B>
<UL>
<LI>Small increase of visible energy deposition in sampling calorimeters
(e.g. 0.5% for a simplified setup with materials of the ATLAS EM barrel calorimeter)
due to improvements in the multiple scattering model.</LI>
<LI>Improved tails of energy deposition in thin absorbers.</LI>
</UL>
<B>Hadronic physics</B>
<UL>
<LI>Improved treatment of low mass strings in the FTF model allows the model
to be used at lower energies and provides a smoother transition in energy
response in the region where string models give way to cascade models.</LI>
<LI>Improved memory management in the Bertini cascade model results in a
10-fold reduction of object creation and destruction. The model also
conserves energy and momentum better.</LI>
<LI>Fermi Break-up Model and GEM evaporation are used by default providing
improved production of light fragments in nuclear fragmentation at low
energy.</LI>
<LI>Improved spectra of nuclear gamma deexcitation including Doppler
broadening simulation.</LI>
<LI>Fast neutron cross-sections can provide significant CPU savings for
applications which need accurate simulation of neutrons below 20 MeV.</LI>
<LI>Materials defined with an effective Z or A can no longer be used
with hadronic processes.</LI>

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

<A NAME="8."></A>
<HR>
<!-- ============================================== -->
<H2>8. Known Run-Time Warnings</H2>
The following message may be written to standard output at the end of a program:
<PRE>
G4Transportation: Statistics for looping particles
Sum of energy of loopers killed:
Max energy of loopers killed:
</PRE>
It provides the total energy (in <TT>MeV</TT>) of tracks killed due to
excessive number of steps ('looping') during the simulation, and the maximum
energy of such a track. Such behaviour can be due to looping in magnetic fields
or being abandoned due to being stuck at geometrical boundaries.
<P></P>
In case either of these reported energies is significant, we recommend
increasing the verbosity of <TT>G4Transportation</TT> to obtain information for
each track killed. A user can change the threshold energy above which particles
are killed more reluctantly (only after significant additional effort) using
the method <TT>SetThresholdImportantEnergy()</TT> of <TT>G4Transportation</TT>.
The default value is <TT>100 MeV</TT>.

<A NAME="vis-notes">
<H3><I>Visualization</I></H3></A>
<UL>
<LI><B>Management</B>
<UL>
<LI>Added new <TT>/vis/open</TT> command for OpenGL viewers,
<TT>/vis/open OGL</TT>.
This new form allows the same macro to be used whether one is on
Linux or Windows (calling OGLSX on Linux and OGLSWin32 on Windows).
When the application has been built with Qt, it will use the Qt form
of OpenGL; when built with Motif, it will use the Motif form of OpenGL.
Also added options OGLI and OGLS to force Immediate or Stored modes.
The user is still free to use the older, specific viewer names, such
as OGLIX, but the simple form, OGL, will give the most portable macros.</LI>
<LI>Added new <TT>/vis/open</TT> command for OpenInventor, <TT>/vis/open OI</TT>.
This new form allows the same macro to be used whether one is on Linux
or Windows (calling OIX on Linux and OIWin32 on Windows).</LI>
<LI>Added <TT>/vis/scene/add/digis</TT> and <TT>/vis/filtering/digi</TT>
commands, analogous to the already-existing commands
<TT>/vis/scene/add/hits</TT> and <TT>/vis/filtering/hits</TT>.
As with hits, it remains the user's responsibility to provide the
digitisation classes.
Added method <TT>AddCompound(const G4VDigi&)</TT> to drivers.</LI>
<LI>Introduced DispatchToModel without <TT>i_mode</TT>. The archaic form
<TT>G4VTrajectory::DrawTrajectory(i_mode)</TT> is replaced by the
newer form, <TT>G4VTrajectory::DrawTrajectory()</TT>. <TT>i_mode</TT>
used to be a parameter to control whether the trajectory was drawn as
a line, a line plus step points, or only step points:
<UL>
<LI>'i_mode > 0' meant draw lines and points, size of points in
'pixels = abs(i_mode)/1000'</LI>
<LI>'i_mode = 0' meant draw only lines</LI>
<LI>'i_mode < 0' meant draw only points, size of points in
'pixels = abs(i_mode)/1000'</LI>
</UL>
Since release 8.1, better control has been available from the command
<TT>/vis/modeling/trajectories</TT>. Since release 5.0, <TT>i_mode</TT>
less than 1000 has in fact drawn no points and <TT>i_mode</TT> of 1000
has drawn points that were so small (a single pixel wide) that they
were overshadowed by the trajectory itself except at endpoints of the
trajectory or where the trajectory made a sharp change of direction.
Use of <TT>i_mode</TT> is now trapped and a warning gets printed.</LI>
<LI>Changed order of flags to follow <TT>G4UIExecutive</TT>.</LI>
