yes - you should push the new ones. not sure what changed on the existing
ones. can you tell what the changes are? if it is just the order of keys
changing or the order of vertices or something like that then i wouldn't bother
to push it, but if it's something else i would wonder if there is something
wrong somewhere because we should be 100% backward compatible with GraphSON
1.0..........nothing should have changed in that sense.
