<!-- ============================================== -->
<H2>3. Items for migration of the user code</H2>
Listed here is some relevant information on developments included in this
release.
Note that for all users a full re-installation of libraries (or a full
re-compilation) and a re-compilation of user applications is required.
<P> </P>
<B>General</B>
<P> </P>
<UL>
<LI>Minimum required version of CMake to build Geant4 is 3.3.</LI>
<LI>Due to the migration from POSIX threading to C++11 threading, enabling
multi-threading on Windows for use with either static or dynamic
libraries, the following migration is required:
<UL>
<LI>Any usage of <TT>G4THREADCREATE</TT> should pass a reference to an
allocated <TT>G4Thread</TT> pointer.</LI>
<UL>
<LI><TT>G4THREADCREATE</TT> (previously a macro) is
now a variadic template function that accepts an unlimited
number of arguments to the function launched on the thread.</LI>
<LI><TT>G4Thread t; G4THREADCREATE(&t, myfunction, myarg);</TT>
is no longer valid</LI>
<LI><TT>G4Thread* t = new G4Thread();
G4THREADCREATE(t, myfunction, myarg);</TT> is required</LI>
</UL>
<LI><TT>G4MUTEX_INITIALIZER</TT>, <TT>G4MUTEXINIT</TT>, and
<TT>G4MUTEXDESTROY</TT> are now empty macros and their usage is
unnecessary and thus deprecated.</LI>
</UL></LI>
</UL>
<P> </P>
<B>Geometry</B>
<P> </P>
<UL>
<LI>The behaviour of G4Transportation and G4CoupledTransportation
concerning the treatment of looping particles has been reviewed:
<UL>
<LI>From this release on, only stable particles are killed if they
'loop', i.e. take more than the maximum (default 1000) integration
steps in one physics step; unstable particles are now propagated
indefinitely.</LI>
<LI>Warning exceptions with full details of the particle, location and
volume are now generated for stable looping particles which are killed
(as before, this only happens if their energy exceeds a threshold
'warning' energy).
In previous releases a short message with only energy and location
was generated, and only for installations which did not use
G4_NO_VERBOSE. Typically these warnings occur predominantly in vacuum
or other low density media.</LI>
</UL></LI>
<LI>As before the killing of loopers and potential warnings are controlled by
two energy thresholds and a step number parameter. Default settings imply:
<UL>
<LI><TT>100 MeV</TT> (warning energy): below this, tracks are killed
silently.</LI>
<LI><TT>250 MeV</TT> (important energy): above this, tracks are given
multiple chances (10 physics steps).</LI>
</UL>
These settings are fully under user control. The new methods in
G4PhysicsListHelper allow the user to select a set of low (or the above
high) values of the 'looper' energy thresholds.
Existing methods of G4[Coupled]Transportation can be used for fine-grained
control of the parameter values.
Additional information regarding how to reduce the incidence of looping
particles is provided in an expanded section on Transportation in the
Users Guide for Applications Developers.</LI>
<LI>G4MagneticField has been corrected to no longer inherit from
G4ElectroMagneticField; this anomaly used to allow a user to provide a
'full' EM field (mixed electric and magnetic), but obtain the force only
from the B-field when using the equation created in the G4ChordFinder
constructor. With this correction it is no longer possible to use the
equation of motion for a pure magnetic field for the case of a mixed
electromagnetic field. Instead the full chain of classes for equation
of full EM field, steppers and driver must be used for the case of the
'full' EM field.</LI>

<B>Electromagnetic and optical physics</B>
<P> </P>
<UL>
<LI>The new data set G4EMLOW-7.7 should be used.</LI>
</UL>
<P> </P>
<B>Hadronic physics</B>
<P> </P>
<UL>
<LI>The new data sets <TT>G4PhotonEvaporation-5.3</TT>, <TT>G4INCL-1.0</TT>,
<TT>G4RadioactiveDecay-5.3</TT>, <TT>G4SAIDDATA-2.0</TT> and
<TT>G4PARTICLEXS-1.1</TT> should be used.</LI>
<LI>Requiring new <TT>G4INCL-1.0</TT> data set and corresponnding G4INCLDATA path
environment variable when using INCLXX physics.</LI>
<LI>The old G4NEUTRONXS data set is now replaced by <TT>G4PARTICLEXS-1.1</TT>,
and the corresponding G4PARTICLEXSDATA environment variable should be
now used.</LI>
</UL>
<P> </P>
<B>Analysis</B>
<P> </P>
<UL>
<LI>The default mode for Root n-tuple merging (in multi-threaded runs) is
changed to row-wise in order to preserve an "event point of view" (the
n-tuple rows) after merging. The output files written with this mode use a
different data schema (organisations of TBranches and TLeaves) than
before and so require adapting the macros for reading back the data.</LI>
</UL>
<P> </P>
<B>Data Sets</B>
<P> </P>
This release introduces new data set versions.
Please see the corresponding details in
<A href="#data-notes">Section 9</A> of this document.
<UL>
<LI>New data set versions: <TT>G4EMLOW-7.7, G4RadioactiveDecay-5.3,
G4PhotonEvaporation-5.3, G4INCL-1.0, G4SAIDDATA-2.0,
G4PARTICLEXS-1.1</TT>.</LI>
<LI>In order to use <TT>ParticleHP</TT> for charged particles
(protons, deuterons, tritons, He3 and alphas), an optional data
set <TT>G4TENDL-1.3.2</TT> is required, and should be downloaded in
addition from the

<!-- ============================================== -->
<H2>4. New Developments and Capabilities </H2>
<B>General</B>
<UL>
<LI>Replaced POSIX threading with C++11 threading, enabling multi-threading
on Windows for use with either static or dynamic libraries.</LI>
<UL>
<LI><TT>G4THREADCREATE</TT> is now a variadic template function
(unlimited arguments) instead of a macro</LI>
<LI><TT>G4THREADCREATE</TT> can be used outside of MT. In sequential
mode, <TT>G4THREADCREATE</TT> will execute the function on the
calling thread.
</UL>
<LI><TT>G4Mutex</TT> is now a typedef to <TT>std::mutex</TT>,
even in sequential mode.
<LI>Added <TT>G4RecursiveMutex</TT> typedef to
<TT>std::recursive_mutex</TT>.</LI>
<LI>Provided generic template functions <TT>G4TypeMutex&lt;T&gt;()</TT> and
<TT>G4TypeRecursiveMutex&lt;T&gt;()</TT> to create and access static
instances of mutexes without the need for declarations.</LI>
<UL>
<LI>When combined with <TT>G4AutoLock</TT>, this enables easy creation of
class-specific locks, e.g.
<TT>G4AutoLock lock(G4TypeMutex&lt;decltype(this)&gt;());</TT></LI>
</UL>
<LI><TT>G4AutoLock</TT> now inherits from <TT>std::unique_lock</TT>, even in
sequential mode.</LI>
<UL>
<LI>In sequential mode, <TT>G4AutoLock</TT> does not lock upon construction,
i.e. <TT>std::defer_lock</TT></LI>
<LI>Added overloads to accept reference to mutex, in addition to previous
form of a pointer to a mutex.</LI>
</UL>
</UL>
<B>Analysis</B>
<UL>
<LI>Switched the default Root ntuple merge mode to row-wise in analysis
tools and added new <TT>G4RootAnalysisManager::SetNtupleRowWise(G4bool)</TT>
function which can be used to override the defaults. </LI>
<LI>Added "Boolean reset" argument in <TT>G4AnalysisManager::CloseFile()</TT>
function, allowing to close a file without resetting data.</LI>
</UL>
<B>Digitization &amp; Hits</B>
<UL>
<LI>Added new class G4StatAnalysis, a lightweight statistics class that
calculates the mean, FOM, relative error, standard deviation, variance
and other quantities. Compatible with usage in G4THitsMap and (new)
G4THitsVector -- replacing <TT>G4THitsMap&lt;G4double&gt;</TT> with
<TT>G4THitsMap&lt;G4StatAnalysis&gt;</TT> and can provide a quick
implementation of accumulating statistics for scoring.</LI>
<LI>Added new class G4THitsVector, a generic hits container compatible with
G4THitsMap, that enables the underlying storage container to utilize a
sequential container instead of a map (saving memory); additionally, it
allows the underlying container to store data as non-pointer types
(saving more memory).</LI>
<UL>
<LI>These containers are intended to be used at the G4Run level to
accumulate data over the course of the run and it is not recommended
for use at the event level -- a G4THitsMap is ideal at the event level
due to the general sparsity of hits per index but at the run level,
G4THitsVector becomes ideal with respect to memory usage as
approximately 40% of the total available indices accumulate non-zero
hits.</LI>
<LI>See <I>DICOM2</I> and <I>ThreadsafeScorers</I> for usage examples,
including demonstrations of G4THitsVector + non-pointer data storage
and the new style of generic iteration over the hits container classes
that is valid for both G4THitsMap and G4THitsVector (the previous form
of iteration over G4THitsMap is still valid, and will remain valid,
for G4THitsMap types).</LI>
</UL>
<LI>Introduced a new interface class, G4VScoreNtupleWriter, which allows
automated storing of scorers hits with Geant4 analysis tools. Concrete
implementations (G4ScoreNtupleWriter with associated messenger) are
demonstrated in new provided extended/analysis examples.</LI>
</UL>
<B>Geometry</B>
<UL>
<LI>A configuration option allows an installation to use the
<A HREF="https://gitlab.cern.ch/VecGeom/VecGeom/">VecGeom Unified Solids
Library</A> primitives, to replace the original Geant4 solids, as in the
previous release. The path to an external installation of the VecGeom
library (VecGeom version <TT>v01.01.00</TT>) should be specified.
See the associated instructions file for configuration and installation.</LI>
<LI>Enabled VecGeom wrappers for G4ExtrudedSolid, G4TessellatedSolid, G4Hype
and G4Tet.</LI>
<LI>Reimplemented <TT>EstimateSurfaceArea()</TT> for approximate calculation
of the surface area of a solid with new algorithm providing more
accurate estimation without performance penalty.</LI>
<LI>Introduced Bulirsch-Stoer method of integration, an alternative to
Runge-Kutta based on the mid-point method.</LI>
<LI>New G4InterpolationDriver field driver class using Runge-Kutta method
with interpolation property to integrate EoM with error control.</LI>
<LI>Updated field steppers to make use of cached field vales.</LI>
<LI>Improved reporting of looping particle, adding info on density,
fraction (%) of proposed step that was completed and momentum.</LI>
</UL>
<B>Electromagnetic physics</B>
<UL>
<LI>Use new parameter <TT>MscEnergyLimit()</TT> (default is <TT>100 MeV</TT>)
in EM physics constructors, allowing to customise transition from
low-energy multiple scattering to high energy combination of multiple
and single scattering.</LI>
<LI>Alg96 lateral displacement algorithm used in G4UrbanMscModel in all
EM physics.</LI>
<LI>Default angular generator for bremsstrahlung is G4ModifiedTsai.</LI>
<LI>Revisions of G4BetheHeitlerModel and G4PairProductionRelModel with
improved screening function approximation, improved LPM function
approximation, angular generation and efficiency of sampling
of the final state.</LI>
<LI>New gamma conversion model G4BetheHeitler5DModel.</LI>
<LI>Added optional possibility to use ICRU90 data.</LI>
<LI>New optional ion ionisation models G4LindhardSorensenIonModel,
G4AtimaEnergyLossModel, G4AtimaFluctuations.</LI>
<LI>Added new classes for the simulation of elastic scattering of gammas.</LI>
</UL>
<B>Hadronic physics</B>
<UL>
<LI>For both Fritiof (FTF) and Quark-Gluon-String (QGS) string models,
we have released the latest versions, which have been developed since
the release 10.2 but have not been included in the two previous releases,
10.3 and 10.4, to keep stable the simulation of hadronic showers
(note that snapshots of these developments have been made available
in previous beta releases: 10.3.beta, 10.4.beta and 10.5.beta).</LI>
<LI>New tuning of the FTF model parameters, for both string formation
and string fragmentation. Introduced smearing of delta-isobar mass and
improved di-quark fragmentation into baryons in Lund string fragmentation.

fragmentation, with introduction of Mt distribution of hadrons.
Improved process probability parameterizations for Pi-Nucleon interactions;
corrected calculation of nuclear residual excitation energy.</LI>
<LI>Major revision of the QGS final-state model: implemented Reggeon cascading
and "Fermi motion"; new algorithm for the determination of the kinematical
properties of partons; improved formation of the residual nucleus.
Improved cross-sections of K-meson - nucleon interactions in QGS: Pomeron
and two non-vacuum exchanges are taken into account.
Gamma-nucleon cross sections are also improved by tuning of parameters.
Improved string fragmentation (G4QGSMFragmentation): new algorithm for
last string decay a-la Lund is implemented; refined the algorithm to stop
the fragmentation.
Tuning the parameters related to both string formation and string
fragmentation to improve the description of thin-target data.</LI>
<LI>For both string models (FTF and QGS): first implementation of alpha
cluster structure of carbon nuclei (affecting only hadron-Carbon
interactions), according to P.Bozek et al., Phys.Rev.C90, 064902 (2014).</LI>
<LI>For Bertini Cascade, extended strange pair production channels, and
improved pion-quasideuteron reactions.</LI>
<LI>Extended upper limit of applicability (from 1 to <TT>100 TeV</TT>) for the
diffuse-elastic processes.</LI>

if a command is rejected due to the target class or the messenger.</LI>
</UL>
<B>Examples</B>
<UL>

<LI><I>field01</I>: Added code to demonstrate use of G4PhysicsListHelper's
<TT>Use[Low|High]LooperThresholds()</TT> methods and code to demonstrate
fine grained control of G4[Coupled]Transportation parameters for (killing)
looping tracks (tracks which take too many iterations to finish integration;
typically due to electrons in vacuum, but also can affect other charged
particles).</LI>

<H2>5. Expected effects on physics and computing performance</H2>
<B>Electromagnetic physics</B>
<UL>
<LI>Extended G4SeltzerBergerModel model with optional sampling tables for
faster run time sampling of the emitted photon energy. Measuring 40-60%
model speedup.</LI>
</UL>
<B>Hadronic physics</B>
<UL>
<LI>Both hadronic string models (FTF and QGS) describe generally better the
thin-target data with respect to the previous versions.
Moreover, the QGS model becomes competitive with the FTF model, for
most thin-target observables for projectile kinetic energies above
about 20 GeV.</LI>
<LI>For the simulation of hadronic showers, both hadronic string models
give higher energy response with respect to the previous versions,
and consistently higher when compared with test-beam and collider data.
We believe at least part of this is due to an underestimate with the Birks
quenching factor which must be applied to the simulation in order to
compare to measured data. The Birks coefficient is a phenomenological
function of energy loss and not of energy deposit. It therefore neglects
the effect of discrete delta ray production performed in Geant4.
We therefore suggest re-fitting from data the Birks coefficient to the
h/e ratio: energy response of a hadron (charged pion or proton) at a
given energy with respect to the energy response of an electron of the
same energy.</LI>

and Pt for baryons 3/2 production at <TT>900 MeV/c</TT>.</LI>
<LI>Fine tuning of G4LundStringFragmentation (for the string fragmentation
of the FTF model). Pt of mesons created at quark fragmentation is
decreased. Pt of baryons created at quark and di-quark is increased.
Corrected fragmentation functions of <TT>qq-&gt;B(1/2)</TT> and <TT>B(3/2)</TT>.
Re-organized and cleaned up code; the variant is tuned using NA49
experimental data on <TT>pp-&gt;p/pi/K +X</TT>.</LI>
<LI>Introduced smearing of delta-isobar mass in the FTF model;
delta-isobars are now treated as a kinetic track; improved
parameterisation of the quark exchange process with excitation.
NA61/SHINE exp. data on Pi+, Pi-, K+, K- and protons in PP interactions
at 20, 31, 40, 80 and 158 <TT>GeV/c</TT> are now described. Now
reproducing the ratio of &lt;Strane Q&gt;&sol;&lt;Normal Q&gt; in PP
interactions. Not describing kink in AA interactions.</LI>
<LI>Improved di-quark fragmentation into baryons in Lund string
fragmentation (used in the FTF model). Improved description of NA49 and
NA61/SHINE experimental data on <TT>p+p-&gt;p+X</TT>. Improvements in
the method SetMinimalStringMass(), relevant for Pbar P annihilation.</LI>
<LI>In the FTF model, improved process probability parameterizations for
Pi - Nucleon interactions. Good results are obtained for HARP data
(<TT>p/Pi+/Pi- + A</TT> at <TT>3, 5, 8, 12 GeV/c</TT>) and for Pi N
inclusive reactions.</LI>
<LI>Corrected calculation of nuclear residual excitation energy in the FTF model.
Fine tuning of the FTF model parameters.</LI>
<LI>For the FTF model, set to false the switches for the A-dependence
in nuclear destruction for baryon projectile in G4FTFParameters.
Uncommented checks for these switches in the code. No changes in the
random number sequence.</LI>
<LI>Improved versions and tuning of Lund and QGS fragmentations
(used, respectively, by FTF and QGS string models).</LI>
<LI>G4LundStringFragmentation: bug fixes related to rotating strings
in the FTF model.</LI>
<LI>G4VLongitudinalStringDecay: removed useless caching in the method
FragmentationMass() which was causing rare irreproducibilities in
gamma-nuclear reactions (i.e. involving QGS).</LI>
<LI>Improved QGS model and fixed issue of event reproducibility in
gammma-nuclear.</LI>
<LI>Fixed leak in <TT>G4QGSParticipants::GetList()</TT> for targets not deleted
after interaction.</LI>
<LI>G4QGSParticipants: introduced protection in the QGS model against
negative squared mass in the method <TT>PutOnMassShell()</TT>, which was causing
some rare crashes. If a negative squared mass occurs, a <TT>JustWarning</TT>
exception is thrown and the squared mass is set to 0, before calling
the square root (which is now computed only once).</LI>
<LI>Moved G4PomeronCrossSection class to 'qgsm' module.</LI>
<LI>G4FTFAnnihilation: fix to get flat <TT>cos(theta)</TT> and <TT>phi</TT>
distributions for antiproton annihilation at rest in the FTF model.
Added also a protection for the evaluation of the rapidity.</LI>
<LI>G4FTFModel, G4DiffractiveExcitation, G4FTFAnnihilation: code
improvements of the FTF model. No changes in physics output, but with
possible differences in the random sequence, due to numerical effects
caused by re-ordering of operations.</LI>
<LI>G4LundStringFragmentation: tuning of strange - anti-strange probability
production, for the FTF model, as a function of energy to describe
NA61/SHINE <TT>31 GeV/c p-C</TT> data on <TT>K+ / K-</TT> production.
Decreased also the Lambda0 production for NA61/SHINE <TT>158 GeV/c</TT>
and <TT>31 GeV/c p-C</TT>: for the former good agreement,
while for the latter the simulation underestimates the data.</LI>
<LI>G4QGSMFragmentation: implemented new algorithm for the last string decay
a-la Lund. Improved the algorithm to stop the fragmentation of QGS strings.
Tuning of parameters with NA49 and NA61/SHINE data was performed.</LI>
<LI>G4Reggeons: improved cross-sections of K-meson - nucleon interactions
in the QGS model. Taken into account Pomeron and 2 non-vacuum exchanges.
Initial parameters for kaons are taken from Kaidalov's paper (1976).
Improved gamma-nucleon cross-sections by tuning of parameters.</LI>
<LI>Fix in <TT>G4FTFModel::GetStrings()</TT> to return a vector with
size zero in wrong conditions for FTF.</LI>
<LI>G4VPartonStringModel: in cases of wrong conditions for the QGS model,
the initial particle/nucleus is returned, according to a similar fix in
FTF model.</LI>

guidance and parameters from <TT>/vis/scene/add/...</TT>.</LI>
<LI><TT>/vis/scene/add/trajectories</TT>: avoid adding new model if one
exists. If no trajectories model exists in the scene create a new one...
else it already exists and there is no need to add a new one
because G4TrajectoriesModel simply describes trajectories in the
trajectories store whatever the type.</LI>
<LI>Added <TT>/vis/touchable/findPath</TT> UI command.</LI>

<LI>Open header files to users. In all header files, changed guards
(similarly for OPENGLX, XM, QT, WT and WIN32), so that a user may
include the OpenGL headers and use the OpenGL library. This will be

<LI>Replaced local physics with FTFP_BERT + G4OpticalPhysics; deleted
custom lists LXeEMPhysics, LXeGeneralPhysics, LXeMuonPhysics and
LXePhysicsList; use G4EmStandard_option4 EM physics.</LI>
<LI>Added LXeRun to record and print results at the end.</LI>
<LI>Removed LXeSteppingVerbose and cleanup of macros.</LI>
<LI>Removed LXeUserEventInformation, use LXeEventAction instead;
removed LXeRecorderBase, replaced with LXeHistoManager.</LI>
<LI>Removed unneeded direction named random.</LI>
<LI>Fixed MT issue: random directory should not be set via EventAction,
this functionality is moved to DetectorConstruction.</LI>
<LI>LXeDetectorConstruction: removed definition of random number
directory from the code, user may define this via UI command.</LI>
