[newbie] 7.0 vs 7.2

[jeff]

I just received 7.0 for linux mall for a buck 98, but now I see folks
talking about 7.2.

Is there a large difference, something I should be concerned about?

Also a bit off subject, but some told me about 3d labs is going to have
a new product that is supposed to shoot the stock through the roof. I
have watch the stock and it has gone up a good bit. Does anyone know
what it is?
