+Dec 11th, 2009 - J.Apostolakis (geomnav-V09-02-11)
+------------------------------
+- G4PropagatorInField
+  * Implementation field by Region 
+      - with extra checking of logical volume
+
+Nov 30th, 2009 - J.Apostolakis (geomnav-V09-02-10)
+------------------------------
+- G4VIntersectionLocator
+  * Fix problem in ReEstimateEndPoint() behaviour for very small steps.
+
+  * Corrected constructor to ensure that it initialises all data members.
+  * Labelled the methods (in header) to make noticable those that 
+      must changed at every step.
+      ( attributes: ChordFinder,  EpsilonStep,  Navigator )
+
+Nov 23rd, 2009 - J.Apostolakis 
+------------------------------
+- Fixed G4PropagatorInField.cc: 
+   * Revise condition for flagging ZeroStep to avoid fake triggering.
+     Small proposed steps (from Physics) could trigger the previous
+     simple condition for Tiny/Zero Problem steps.
+   [ This was first commited on branch geomnav-V09-02-08_branch 
+       and tagged geomnav-V09-02-80  ]

+Nov 12th, 2009 - J.Apostolakis (geomnav-V09-02-09)
+------------------------------
+- G4PropagatorInField: cleanup of minor methods:
+   Added new method RefreshIntersectionLocator to update the state of
+       Use this method to synchronise with IntersectionLocator.
+   Deleted long obsolete methods: SetAccuraciesWithDeltaOneStep
+           SetDeltaIntersection,  SetDeltaOneStep
+   Revised implementation to avoid using the older methods
+           GetDeltaIntersection   GetDeltaOneStep
+
+Nov 12th, 2009 - J.Apostolakis (geomnav-V09-02-08)
+------------------------------
+- Refined G4PropagatorInField.cc: 
+   * Changed parameters for treating consecutive tiny/zero steps:
+     - the value of default decrease factor to 0.25 (from 0.1), 
+     - the value is not used when the step size falls below a certain threshold.s
+       This threshold is changed. It is expressed as a multiple of fZeroStepThreshold 
+       instead of kCarTolerance.  The reasons are:
+         * the threshold were meant to refer to the  ZeroStepThreshold (it was kCarTolerance)
+         * the values were now much larger than this ZeroStepThreshold.
+     - The value given to the decrease factor after the first such thresholds is changed to 0.35
+       instead of 0.25, 0.5.  
+   * Improved printing of Diagnostic message.
+
+Nov  3rd, 2009 - J.Apostolakis (geomnav-V09-02-07)
+------------------------------
+- Refined G4PropagatorInField.cc: 
+   * Added new member fZeroStepThreshold, to enable tuning of threshold for Tiny/Zero steps. 
+   * Changed default value from 0.5 * kCarTolerance 
+                          to max (100,000 * kCarTolerance, 0.1 * micron )
+   * This is first revision to address problem seen at boundary of volumes (Reports of Atlas) .
+
+June 2nd, 2009 - J.Apostolakis (geomnav-V09-02-06)
+------------------------------
+- Fix in G4PropagatorInField::SetNavigator
+   * Forward new Navigator to IntersectionLocator.
