This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.
It DOES NOT substitute the  CVS log-message one should put at every
committal in the CVS repository !

-Sep. 19 2008   H.Kurashige (decay-V09-01-04)
- modify process sub type enumeration

- Aug. 22,  08 P.Gumplinger (decay-V09-01-03)
- fix a bug in G4DecayWithSpin.cc: there is a memory overwrite when the
  GetFieldValue being called initializes a fieldValue array of size 6
  when the array is only defined of size 3 in the calling program.
  Thanks to Kamil Sedlak (PSI) for pointing this out and suggesting this
  fix.
 
- Apr. 16,  08 H.Kurashige  (decay-V09-01-02)
- fix a bug when shortlived particles has finite  pre-assigned proper time
 
- Apr. 11,  08 P.Gumplinger (decay-V09-01-01)
- modify G4DecayWithSpin::DecayIt to allow spin precession also for EM Fields;
  e.g. fields that do "DoesFieldChangeEnergy()" but only if the B-field
  component is > 0. (thanks to Kamil Sedlak, Toni Shiroka from PSI)

- Dec. 15,  07 H.Kurashige (decay-V09-01-00)
- add G4DecayProcessType
- define process sub type

- Oct. 29,  07 P.Gumplinger (decay-V09-00-02)

  set the daughter muon spin for 2 body decays of
  pi, K and K0_long

- Oct. 12,  07 H.Kurashige (decay-V09-00-01)

- Add G4DecayWithSpin class and allow for dependency to
  /geometry/navigation in GNUmakefile
