* Reverse chronological order (last date on top), please *
----------------------------------------------------------
August 28th 2017, G.Cosmo transport-V10-03-02
--------------------------------
- Make appropriate setting/use of verbosity from base class G4VProcess,
instead of re-defining/using local verbosity flag in G4Transportation
and G4CoupledTransportation.
Addressing problem report #1999.
August 28th 2017, G.Cosmo transport-V10-03-01
--------------------------------
- Fixed use of G4DEBUG_TRANSPORT flag in G4CoupledTransportation.
August 25th 2017, J.Apostolakis transport-V10-03-00
--------------------------------
- G4CoupledTransportation & G4Transportation: obtain equation of motion
using dedicated method of ProgatorInField.
Smaller code, and future proof.
February 12th 2015, J.Apostolakis transport-V10-01-03
--------------------------------
- G4CoupledTransportation:: Made SignifyStepInAnyVolume 'flag' static.
Stoped using IsLastStepInVolume for step limitation.
January 20th 2015, J.Apostolakis transport-V10-01-02
--------------------------------
- G4CoupledTransportation: Added ability to identify first step in a volume in either
the mass geometry or in any geometry. Also added flag for last step in a volume
in the mass geometry.
Extends fix of tag transport-V10-01-00.
Since it is not clear whether user wants/needs to identify the first/last in
any geometry or just in the mass geometry, allowing this to be a choice:
Configurable: whether the flag represents a first/last step in mass geometry
or any geometry (currently the default - what was the case for last step before).
Also depends in geomnav-V10-01-02 and track-V10-01-00.
Addresses Bugzilla issue #1032.
January 10th 2014, M.Kelsey transport-V10-01-01
---------------------------
- G4Transportation.cc, G4CoupledTransportation: In
AlongStepGetPhysicalInteractionLength(), initialize restMass data member
using G4DynamicParticle (as is used in DoIt), not G4ParticleDefinition.
Resolves inconsistent kinematics when dynamic mass is measurably different
from "PDG" mass.
December 17th 2014, J.Apostolakis transport-V10-01-00
---------------------------------
- G4Transportation: Added ability to identify last step in volume for the case of
propagation in field.
Requires use of tags in navigation (geomnav-V10-01-02) and track (track-V10-01-00) .
Addresses Bugzilla issue #1032.
November 21st 2014, J.Apostolakis transport-V10-00-06
--------------------------------- (corrected version of transport-V10-00-04)
- Added initialization of G4CoupledTransportation data members (fixes Coverity issue 15280)
Renamed data member, to make its name canonical.
October 15th 2014, M.Asai transport-V10-00-05
-------------------------
- G4CoupledTransportation is reverted to transport-V10-00-03.
- G4Transportation and G4CoupledTransportation : made data member
fUseMagneticMoment and its set method EnableUseMagneticMoment()
static.
May 27st 2014, V.Ivanchenko transport-V10-00-03
------------------------------
- G4UserSpecialCuts - fixed trivial Coverity report
May 21st 2014, J.Apostolakis transport-V10-00-02
------------------------------
- Revised AlongStepDoIt methods of G4Transportation and
G4CoupledTransportation:
* Adapted to revised signature for G4FieldTrack constructors,
which now take PDG spin.
* Changed to use different constructor for G4FieldTrack (no Velocity)
* Adapted to revised signature of G4ChargeState constructor (PDG spin is
now 3rd argument and mandatory. )
NOTE: Requires tag field-V10-00-03 of geometry/magneticfield
March 14th 2014, J.Apostolakis transport-V10-00-01
------------------------------
- Fix time in case of zero step, in G4CoupledTransportation.
This caused a 'going back in time' error, when a zero step occurred
in particular at the boundary of a parallel world volume when scoring.
> Corrects Issue 1017 in the Geant4 Problem reporting System
http://bugzilla-geant4.kek.jp/show_bug.cgi?id=1017
NOTE: Requires tag geomnav-V10-00-01

------------------------------------------
- Adapted G4Transportation and G4CoupledTransportation to use G4ChargeState
for charge/spin/magnetic moment, and to message the equation of motion
directly with it.
The tag(s) above co-work with and requires the following tags:
had-binary-V09-06-05, geomnav-V09-06-06 and field-V09-06-04.

------------------------------
- G4Transportation.cc:
Corrected issues with initilisation of data members reported by Coverity.
Renamed data member endpointdistance to fEndPointDistance (to conform).
Jul. 5th, 2012 Gabriele Cosmo transport-V09-05-01
-----------------------------
- Explicitly use inclusion of headers for system of units and physical
constants, in plan to remove implicit inclusion from globals.hh.
Jun. 7th, 2012 Gabriele Cosmo transport-V09-05-00
-----------------------------
- Fixed spurious cases of hidden variable visibility, detected with
'-Wshadow' compilation option on gcc compiler.
Nov. 4th, 2011, J.Apostolakis transport-V09-04-13
-----------------------------
- Turned off tracking for magnetic moment - by default.
It can be enabled in
G4Transportation, G4CoupledTransportation
by using the new method EnableUseMagneticMoment().
Should ensure particles with a moment are not affected
unless user needs this.
Nov. 4th, 2011, J.Apostolakis transport-V09-04-12
-----------------------------
* Reduce overhead of the addition of Gravity
- G4Transportation: Revised condition for gravity field (version 1).
G4CoupledTransportation: Revised the field-detection condition,
with improved logic to cope with ConfigureForTrack (for any field) (v2).
Deleted dependence on G4UniformGravityField in both.
Tag coworks with field-V09-04-05
Nov. 1st, 2011, P.Gumplinger transport-V09-04-11
-----------------------------
- add condition to the condition, gravity != NULL, that the particle's mass is
also restMass != 0.0. Modify G4CoupledTransportation.cc according to
G4Transportation.cc
Oct. 28th, 2011, P.Gumplinger transport-V09-04-10
-----------------------------
- allow for spin tracking of neutral particles with a magn. moment;
allow for uniform gravity field tracking of neutral particles;
tag coworks with field-V09-04-03.
Oct. 28th, 2011, P.Gumplinger transport-V09-04-09
-----------------------------
- remove all special reverence and logic regarding "opticalphoton" from code
in G4Transportation.cc and G4CoupledTransportation.cc
Aug. 8th, 2011, H.Kurashige transport-V09-04-08
---------------------------
- Modify calculation of deltaTime for optical photon in Transportation (and CoupledTransportation)
Use the updated velocity obtained from G4Track::CalculateVelocityForOpticalPhoton
instead of the initial velocity of the step.
(see problem #1239)
[ This is because the velocity at the initial point can refer to
a previous volume. If the PreStepPoint was on a surface, we
the previous step was in another volume, which shared this
PreStepPoint --> and its velocity would be wrong. ]
July 6th, 2011, H.Kurashige transport-V09-04-07
---------------------------
- Modify G4Transportation (and CoupledTtansportation)
to propose the final local time rather than the global time
so that local time can be updated properly.
(see problem #1224)
[ This adapts to the recent change in Tracking, which made
the change of LocalTime trigger the change of Global Time
(instead of vice-versa). ]
June 10th, 2011, J.Apostolakis transport-V09-04-06
------------------------------
- Fix for invalid safety passed to SafetyHelper.
June 10th, 2011, J.Apostolakis transport-V09-04-05
------------------------------
- Fix G4Transportation::AlongStepDoIt
Use only initial velocity to update time. An estimate of velocity
at endpoint is not yet available. (finalVelocity still= initial)
==> It will be updated later in the tracking sequence, when
energy loss is applied, and it will be available to
Transportation only in the PostStepDoIt()
May 26th, 2011, H.Kurashige transport-V09-04-04
---------------------------
- Define ProcessSubType for processes under transportation category
- Change process type of G4NeutronBuilder to fGeneral
January 26th, 2011, G.Cosmo transport-V09-04-03
---------------------------
- Simplified implementation of G4CoupledTransportation::EndTracking(), to
avoid unnecessary static pointer definition.

January 21th, 2011, V.Ivanchenko transport-V09-04-01
--------------------------------
- G4UserSpecialCuts: fixed bug in energy tracking cut; changed order
of checks: 1st energy tracking cut, 2nd track length, 3d time cut,
4th range for charged particles with non-zero mass; removed unnecessary
string comparisons.
January 4th, 2011, M.Asai transport-V09-04-00
-------------------------
- G4CoupledTransportation: added EndTracking() method to reset the
activated navigator list.
September 13th, 2010, J.Apostolakis transport-V09-03-01
-----------------------------------
- Improvement to G4Transportation: copy current safety to SafetyHelper each
time it is computed (it used to be copied only when it was recalculated at
end of step).
September 13th, 2010, J.Apostolakis transport-V09-03-00
----------------------------------
- Retagged - to propose for testing.
November 17th, 2009, J.Apostolakis transport-V09-02-00
----------------------------------
- G4Transportation:
o Fix: Update the Step flag which identifies the Last Step in a volume
It is now done for the linear steps (no charge or no field)
November 26th, 2008, J.Apostolakis transport-V09-01-03
----------------------------------
- G4CoupledTransportation:
o Fix: initialise new data member (in constructor) - found by STT
November 21st, 2008, J.Apostolakis transport-V09-01-02
----------------------------------
- G4Transportation & G4CoupledTransportation:

only when its value comes from ComputeSafety
January 17th, 2008, J.Apostolakis transport-V09-01-00
---------------------------------
- G4Transportation & G4CoupledTransportation:
o Clear state of all Chord Finders using G4FieldManagerStore.
- Syncronised with files on the HEAD.
- Requires co-working tag "field-V09-01-00" (or "field-V09-00-03").
Functionality corresponding to tag "transport-V09-00-52".
November 27th, 2007, J.Apostolakis transport-V09-00-08
----------------------------------
- G4CoupledTransportation
o Added updating of particle-looping flag (was commented out.).
November 10th, 2007, J.Apostolakis transport-V09-00-07
----------------------------------

November 27th, 2007, J.Apostolakis transport-V09-00-05a
----------------------------------
- G4CoupledTransportation
o Added updating of particle-looping flag (was commented out.)
- Also called "transport-V09-00-51" to make it canonical.
November 8th, 2007, J.Apostolakis transport-V09-00-05
---------------------------------
- G4Transportation:
o Created new method (and class member) for flag on Short StepOptimisation.
* When it is true, the optimisation is 'on' steps shorter than the
safety will not call G4Navigator - so long as the particle goes straight
ie it is not charged or there is no field.
* Retained the default value as 'off' - as since changed in
transport-V09-00-02 following Alex's suggestion.
November 8th, 2007, J.Apostolakis transport-V09-00-04
---------------------------------
- G4Transportation (AlongStepGPIL):
o Moved the call to ConfigureForTrack before the check whether
fieldMgr has 0 field ptr, in order to enable it to be called
even if the field manager points to a zero field.
Needed to enable a user to switch a global field on (off was possible),
as a track goes between volume (or regions) of a setup.
[ Response to request of Atlas/ZM. ]
Note: this ordering already existed in G4CoupledTransportation.
October 12th, 2007, J.Apostolakis transport-V09-00-03
---------------------------------
- G4CoupledTransportation:
o Improves condition for flag that regulates Relocating when only
any geometry (including a parallel geometry) limits the step.
New PathFinder method required.
- Requires and co-works with tag geomnav-V09-00-03
October 4th, 2007, J.Apostolakis transport-V09-00-02
--------------------------------
- G4CoupledTransportation:

geometry limited the step.
o Change of condition for recalculation safety (from Alex Howard) used,
as currently it improves stability.
September 25th, 2007, J.Apostolakis transport-V09-00-01
-----------------------------------
- G4Transportation:
Modification to disable 'optimisation' in G4Navigator for small linear
step (ie when a track does less than the safety).
* Relevant only if there is no field, or the particle is neutral
* Temporary measure (in current form) to improve comparison
old / new Transportation (single/old vs coupled with pathfinder).
July 12th, 2007, J.Apostolakis transport-V09-00-00

- Corrected names in Transport, Coupled Transport. (J.Apostolakis)
May 29th, 2007, J.Apostolakis transport-V08-03-10
-----------------------------
- Gone back to G4CoupledTransportation.
o G4Transportation is now the original (what was called G4Transportation8
since "transport-V08-03-03").
o G4Transportation8 still exists, to enable code that utilises it to compile
(transitional). Expect that G4Transportation8 will be taken away asap.
May 29th, 2007, J.Apostolakis transport-V08-03-04
-----------------------------
- G4Transportation. Refined relocation:

to clear propagator state (safety issue in case of overlaps).
May 18th, 2007, J.Apostolakis transport-V08-03-02
-----------------------------
- G4Transportation:
o Corrected full safety at step start, to protect against negative value.

porting changes in G4Transportation since the creation of
CoupledTransportation.
o Also merged branch used for fixes in G4Transportation.cc (1.60.2, 1.60.4)
for convergence to Release 9.0.
- Renamed G4Transportation to G4Transportation8
- G4ProcessPlader changed to reflect these revisions. (A.Howard)

o Added storing of full safety in state; retrieve it after compute step
from PathFinder; calculate them same way at start of step.
o Put back in the code for treating looping particles.
February 15th, 2007, J.Apostolakis transport-V08-02-01
----------------------------------
- G4Transportation: protection against velocity=0 in AlongStep (invalid).
February 15th, 2007, J.Apostolakis transport-V08-02-00
----------------------------------
- G4Transportation: call PropagatorInField to clear state for new track
--> addresses reliabilitiy problem seen by Atlas. This fix is related
to overlaps, clearing the safety value (which is multivalued due
to the overlaps, and thus can become invalid for a new track in
an overlap region.)
November 22nd, 2006, J.Apostolakis transport-V08-01-04
---------------------------------
- Add new classes G4NeutronKiller and G4NeutronKillerMessenger
(created by V. Ivantchenko)

Feb. 6th, 2006, J.Apostolakis/P.MoraDeFreitas transport-V08-00-01
----------------------------------------------
- Corrected problem with suspended tracks - PR# 802.
- Added StartTracking() method which takes over responsibility to
clear the state for a new track, and to message other relevant
component to clear their state (problem report and proposed revision
by P.MoraDeFreitas).
Jan. 16th, 2006, J.Apostolakis transport-V08-00-00
------------------------------
- G4Transportation:
o The particle's charge is now taken from the dynamic particle, so that
it can take into account changes from the interaction of an ion with

and G4ParallelTransport.cc in view of the g4std wrappers migration.
May, 13th, J.Apostolakis transport-V05-01-00
------------------------
- Fixes to G4Transportation.cc to accomodate incorrect and
missing functionality for two use cases:
o a local field when no global field exists (it was not seen)
o overriding an existing global field by a 'zero' field
by creating a local field manager that has a null G4Field pointer
(a use case which did not exist.)
Further work to verify these use cases work is required.

-------------------------
- bug fix in G4TrackLogger
July 11th, 2002 M.Dressel internal-2-transport-V04-01-01
--------------------------------------------------------
- moved the standard scoring classes to run because
they need G4EventManager.
July 10th, 2002 M.Dressel internal-1-transport-V04-01-01
--------------------------------------------------------
- add classes for standard scoreing. Remove G4ScorePrinter and G4Scorer.
G4StandardScorer and G4StandardScoreTable may be used as replacement.
The source file G4StandardScorer.cc may be found in
extended/examples/B09/src because it needs to acces the
G4EventManager.
Jun 13, 2002 M.Dressel transport-V04-00-09
---------------------------------------------

May 29, 2002 M.Dressel internal-2-transport-V04-00-05
--------------------------------------------------------
- bug fix in G4PImportanceWWindowScoreManager.cc
and G4ParallelImportanceManager.hh.
May 24, 2002 M.Dressel internal-1-transport-V04-00-05
-------------------------
- Change in G4VProcessPlacer and G4ProcessPlacer: add member function
RemoveProcess to properly remove a process.
- Add classes for wieght window biasing.
May 02, 2002 M.Dressel
-------------------------
- Change in G4ProcessPlacer: set process vector via process manager not
directly.
- Change in G4ParallelTranport: use StartTracking to signal inital step.
This should help to locate "suspended" tracks.
April 24, 2002 G.Cosmo - transport-V04-00-05
-----------------------
- Added G4DEBUG_TRANSPORT flag in GNUmakefile and (on suggestionh of
J.Apostolakis) replaced to G4VERBOSE in G4Transportation::PostStepDoIt()
for extra-check on volume boundary.
Issues addressed by problem report #130 should now be resolved.
April 10, 2002 M.Dressel - transport-V04-00-04
-------------------------
- Added comments to headers of transportation classes and managers for
importance biasing, to fullfill Software Reference Manual.
Apr 9, 2002 G.Cosmo

Apr 4, 2002 M.Dressel - transport-V04-00-01
---------------------
- Resolved compilation problems on SUN-CC and Linux-egcs.
Mar 28, 2002 M.Dressel - transport-V04-00-00
-----------------------
- First implementation of transportation classes and managers for importance
biasing and scoring. Co-works with "geometry-V04-00-01".
Mar 25, 2002 G.Cosmo
---------------------
- Added dependency to new module geometry/biasing in GNUmakefile.
Dec 8, 2001 J.Apostolakis - transport-V03-02-07
---------------------------
- Activated the killing of 'looping' particles -- to be used also to
abandon (kill) particles that are stuck (eg at boundaries).
[ Fix for problems of stuck particles reported by CMS (P.Arce),
and Atlas (A.Del'Acqua, A.Rimoldi) ]
Nov 28, 2001 J.Apostolakis - transport-V03-02-06
---------------------------
- Fix for the new updating of the time for fields -- correcting previous
tag. By keeping account whether the field changes the energy (and
therefore the velocity) in the field manager.
Requires and co-works with
- "field-V03-02-07"
- "geomvol-V03-02-02"
in order to compile (let alone have any effect.)
Nov 10, 2001 J.Apostolakis - transport-V03-02-05
---------------------------
- Motivated by the use case of an Electric Field,
* in order to achieve reasonable accuracy in time integration,
* and to enable fields that vary with the global time
changed Transportation to try to obtain the delta_time from FieldTrack.
Co-works with and requires "field-V03-02-03" to have any effect.
Nov 9, 2001 G. Cosmo - transport-V03-02-04
------------------------
- Fix in G4Transportation.cc for initialisation of touchable handle.
Nov 8, 2001 G. Cosmo - transport-V03-02-03
------------------------
- Introduced changes to G4Transportation for reference-counted
touchables (R.Chytracek). Added methods GetFreeTouchable() and
SetTheOtherTouchableFree(G4VTouchable*).
Nov 6, 2001 J. Apostolakis - transport-V03-02-02
------------------------------
- Added protection in G4Transportation::AlongStepGPIL for messaging
"ResestStepEstimate" of ChordFinder for the case there is no global field.
** NOTE this is not a perfect resolution (see NOTE in log file). **
--> Thanks to Radovan Chytracek for reporting this problem (move to file log)
Aug 16, 2001 J. Apostolakis - transport-V03-02-01
------------------------------
- Tagged. (This tag requires field-V03-02-00)
Aug 16, 2001 J. Apostolakis
------------------------------
- Erasing state information from previous track at the first step of
each track. (-> this is required to ensure repeatability)
This should eliminate any non-repeatability due to the propagation
in field.
( Requires updated version of G4ChordFinder )
Jul 19, 2001 G. Cosmo transport-V03-02-00
------------------------
- Synchronised with CVS HEAD after introduction of warrenty disclaimer.
- Modified author list in G4Transportation (P.Gumplinger).
Apr 11, 2001 J. Apostolakis transport-V03-01-02
------------------------------
- Corrected the last update of G4Transportation.cc, which overwrote the
value of the spin in the cases where a particle was not charged (eg photon)
or a charged particle was not in a field.
Apr 11, 2001 P. Gumplinger transport-V03-01-01
-----------------------------
- Updated G4Transportation.cc to make spin tracking work correctly:
o Replaced the line originally commented out:
// fTransportEndPolarization= aFieldTrack.GetSpin() ; // Not yet possible
with:
fTransportEndSpin = aFieldTrack.GetSpin();
o Added to the AlongStepDoIt() the following call:
fParticleChange.SetPolarizationChange(fTransportEndSpin);
Mar 19, 2001 J. Apostolakis transport-V03-00-01
------------------------------
- G4Transportation modified to use new FieldTrack, and get Kinetic
Energy from it.
This new FieldTrack together with changes in associated Equation of Motion
classes implement the momentum vector as independent variable in place of
the velocity.
So this tag requires
- new geometry/magneticfield tag "field-V03-00-01", and
- new geometry/volumes tag "geomvol-V03-00-03" for new
G4PropagatorInField ().
Feb 27, 2001 J. Apostolakis (transport-V03-00-00)
------------------------------
- G4Transportation.cc:
* Modified calculation of energy at the end of field step
to make it more accurate at low velocities,
(while remaining correct at high gammas).
This improves the energy determination.
Together with electromagnetic/standard tag "stand-V03-00-03"
this addresses the main problem in propagating in an electric field
(Problem report # 108 )
Sep 22, 2000 V. Grichine (transport-V02-00-00) [recorded by G.Cosmo]
---------------------------
- G4Transportation.cc:
o added formula for Tkin corresponding directly to
relativistic definition of Tkin = Etot - mc^2 = mc^2(gamma -1),
where gamma is a particle Lorentz factor.
o general cosmetics.
Jun 19, 2000 J. Apostolakis (transport-V01-01-02)
------------------------------
- G4Transportation.cc: Set the True Step Length in G4Transportation.cc
- Cosmetic: updated other files to the head, as there were no differences
from it (CVS headers).
May 15, 2000 J. Apostolakis (transport-V01-01-01)
------------------------------
- G4Transportation.cc: Set the material in materialChange, in order to get
correct behaviour for volumes that parameterise the material.
(Fix is dependant on changes to particleChangeForTransport and StepPoint)
- Modified setting of touchable change, in order to preserve const-ness where
it exists.
Nov 25, 1999 J. Apostolakis (transport-V00-01-01)
------------------------------
- G4Transportation.cc: Added protection for the case of a zero step (when
there is a field)
- G4UserSpecialCuts: protection to use min range and min kinE only for
charged particles.
June 9, 1999 J. Apostolakis (transport-01-00-02)
------------------------------
- Added a protection so that full relocation is not used for very small moves.
Dec 4, 1998 J. Apostolakis (transport-00-04-01)
------------------------------
- The Velocity Vector for Transport in a magnetic field is now set correctly.
(previously the scalar velocity was automatically promoted to a 3-vector)
Nov 25, 1998 J. Apostolakis
-----------------------------
- Added the direction to LocateGlobalPointAndUpdateTouchable.
Nov 19, 1998 J. Apostolakis (transport-00-03-04)
------------------------------
- Fixes:
1) The final energy is set equal to the initial energy, because
the PropagatorInField does not calculate it correctly yet. NEEDS Fix
2) If the requested step size is zero and safety is zero, the
step is now considered geometry limited. (This can happen
if a discrete process tries to take a step that is very small
compared to the mean free path.) Problem observed by Laszlo in EM tests.
3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity.
Nov 11, 1998 J. Apostolakis (transport-00-03-03)
------------------------------
- Changes to accomodate new interface of Field:
G4PropagatorInField and G4FieldTrack.
Oct 30, 1998 J. Apostolakis (transport-00-03-02)
-----------------------------
- In the case of magnetic field, a flag that determines whether the
geometry limited the step was not set.
Sep 16, 1998 J. Apostolakis (transport-00-03-01)
-----------------------------
- Checks whether the particle is out of the world volume,
if so it has exited and must be killed.
Aug 28, 1998 J. Apostolakis
-----------------------------
- The PostStepGetPhysicalInteractionLength has fixed (to return kInf)
The boolean flags for touchables are now initialised. & Other small fixes ?
Test code for non-relocating case added (for debugging).
June 08, 1998 J. Apostolakis (trans-06-04)
------------------------------
- Corrected Safety computation for the case of the field (adding endpoint
distance instead of curve length.)
- Added PostStepDoIt method that tries to relocate the particle using
G4ParticleChangeForTransport
- Transportation is no longer a G4ContinuousProcess.
June 08, 1998 J. Apostolakis (trans-06-03)
------------------------------
- Modified it to recomputate Safety at the start of a step. To do this
it uses the previous step's calculated safety and endpoint.
June 08, 1998 J. Apostolakis (trans-06-02)
------------------------------
- Modified it to add re-computation of Safety at the endpoint of a step,
when the safety would become negative. This is done to allow processes
to benefit from a realistic (geometrical) value of the safety. The
request to do this was from EM physics
June 03, 1998 J. Apostolakis (trans-06-01)
------------------------------
- The safety we is now generalised to mean the limit of assumption of all
processes. The AlongStepGPIL input value is not the remainder from the
previous step's geometrical safety.
So the transportation must recalculate the starting point's safety here.
As a zeroeth order approximation we set it to zero.
April 17, 1998 M. Maire [recorded by John Apostolakis]
------------------------
- A new process, G4UserSpecialCuts, was added to allow the
user an alternative method to set some user cuts.
April 15, 1998 H. Kurasige [recorded by John Apostolakis]
---------------------------
- The transportation does the absolute minimum required to conform to
the new scheme for ParticleChange: G4VParticleChange is used in signature.
[ But default G4ParticleChange is still used ].
April 14, 1998 John Apostolakis
