TGeant3 geant321 version number

Hi vmc team,
We've noticed very minor differences between the use of TGeant3 and using geant3.21/14 from cernlib outside of the VMC framework. This has raised a question which is "what is the sub-version of geant3.21 used as part of TGeant3?" Or should we expect that the geant321 code used in TGeant3 has diverged from the original cernlib source, so that this question of which sub-version is not meaningful.
  I've noticed that the sub-version of geant321 in TGeant3 as determined from the package's geant321/gversc.inc is geant3.21/11. It appears however that this sub-version number hasn't changed in some time.   More generally, can you please describe the policy regarding the updates to TGeant3's geant3.21?
For example, are all changes to the most recent cernlib version of geant3.21 included in TGeant3's version, but TGeant3's version may also include additional updates that go beyond cernlib's standard version? Thanks very much for your time.
