Do I need to know the version numbers?

As an user I don't want to know the version number until extremely
necessary, i.e. I'm not switching everyday from 1.0 to 1.1 to 1.2 then
back to 1.1, etc. Eventually I try newer versions of Pharo to see what
I'm missing, and I choose to update acoordingly to the stability of
the whole set of packages concerning my application. It's not like I
evaluate the same "install base packages" script I've evaluated 6
months ago :)

By the way if you want to support internally the package status you
may try the Specifications pattern?

I'm sure I will never load it again. Got it? :)
