There are only three versions of Snowmass for DS Sr. as far as I am aware: v3.0.0; v3.0.4; and the current version, v3.0.5.
I have never heard of or seen v3.0.1, v3.0.2, or 3.0.3.
You can tell which version you are running from the DS Sr.'s display. I would be very surprised if you have a version numbered v3.0.2.
As for which version people like best, that is for another thread.
