+Dec 12th, 2002     G. Cosmo - field-V04-01-06
+---------------------------
+- Moved unused variable 'nStpPr' to debug section in G4MagIntegratorDriver.cc,
+  method AccurateAdvance().
+
+Dec 06th, 2002     G. Cosmo - field-V04-01-05
+---------------------------
+- Merged changes by Makoto for migration to new G4ApplicationState in
+  messengers of unit tests.
+
+Nov 29th, 2002     J. Apostolakis - field-V04-01-04
+---------------------------------
+Further fixes for unitialised variable - in other steppers:
+G4ExplicitEuler, G4ImplicitEuler, G4ImplicitEuler
+
+Large memory leak fix for G4ImplicitEuler, small for ExplicitEuler.
+Test accuracy requirements for spin adjusted.
+
+Nov 20th, 2002     J. Apostolakis - field-V04-01-03
+---------------------------------
+Further fixes for unitialised variables:
+
+* G4MagIntegratorStepper
+  -  Created instance variables for number of Integration, State variables
+
+* G4MagErrorStepper
+  -  Utilise number of State variables to initialise full state of Output.
+
+* G4Mag_SpinEqRhs
+  -  Initialise the values of dydx that we do not update.
+
+Note: Undoing these changes and the ones below would enable the user to see 
+        if undefined values are used in variables that he/she expects to 
+        have integrated.
+      BUT the fix assists us to find truly undefined values elsewhere
+        -- if they exist -- using valgrind.
+
+Nov  9th, 2002     J. Apostolakis - field-V04-01-02
+---------------------------------
+Fixes to address use of uninitialised variable in seting values of FieldTrack
+(this was done by design, but was neither ideal or always well-behaved.)
+Changed:
+
+* G4MagIntegratorDriver
+  - Added instance variables for number of Integration, State variables
+  - Initialise all State variables of Output with values from initial variables.
+  - Only the Integration variables will be integrated
+
+* G4ClassicalRK4 and G4MagErrorStepper
+  - Copy the initial time to intermediate and output C-vectors, 
+     in order to provide a zero-eth estimate value.
+  Note1: Should clean-up this fix, making it similar to Driver (above)
+  Note2: Should *not* be used for time varying field unless created 
+           with at least 8 integration variables
+---------------------------------  
+G4ChordFinder.cc
+  - Correction from zero dChord
+      which is does not update the Unconstrained step estimate (state)
+  - Added instance variables to store number of calls and chord-trials
+      and new print method for 'debugging'
+
+G4Mag_UsualEqRhs.cc
+  - Attempted approximations for speedup  *overwritten* by full inverse sqrt.
+
+
+Oct  29th, 2002   J. Apostolakis - test-V04-01-02
+--------------------------------
+- Changed output of tests for small output change (GeV->MeV)
+
+Oct  29th, 2002   J. Apostolakis - test-V04-01-02
+--------------------------------
+- (Only changed and tagged test subdirectory)
+  Changed tests to use the new method SetChargeMomentumMass of 
+  PropagatorInField in order to be ready for its full use in 
+  G4PropagatorInField.
+  (A key problem at end-July was this non-preparedness of the unit tests.)
+
+Jul  24th, 2002   G. Cosmo - field-V04-01-01
+--------------------------
+- G4FieldManager[.hh.cc]: made fDefault_Delta_One_Step_Value and
+  fDefault_Delta_Intersection_Val normal constants (not static) to
+  resolve initialisation problems. Coworks with tag "geomvol-V04-01-01".
+  Fixes problem report #383.
+
+Jul  23rd, 2002   G. Cosmo - field-V04-01-00
+--------------------------
+- G4MagIntegratorDriver.cc: cleared warning of unused variable.
+  Protected variable 'nStpPr' with G4DEBUG_FIELD.
+- Updated reference outputs and some other updates to unit tests.
+
+Jun  25th, 2002   J. Apostolakis - field-V04-00-05
+--------------------------------
+- G4ChordFinder.cc
+  In NewStep:  fixed case of stepTrial >> stepTrialOld, to take large multiple - not small;
+       (it was treated the same as stepTrial << old)
+  Added guard for stepTrial==0.0 in FindNextChord
+- G4MagIntegratorDriver.cc
+  Added protection against error of 0.0 in ComputeNewStepSize.
+
+- G4EquationOfMotion
+  Made RightHandSide an inline method 
+  In GetFieldValue signature of Point is double[4], instead of double[3]
+  Defined G4maximum_number_of_field_components as enum
+
