WOOPS
I quoted the wrong sentence. Let me correct that. 

I wanted to say I agree with the following sentence:

>  I prefer to support "older versions" on newer versions of GemStone (to a certain extent) so that folks can move forward on GemStone without being forced to change to a different version of Seaside ...

Upgrading from 3.0 to 3.1 is not a difficult task at all actually.
It depends a bit on what you are using/extending, so see the change logs [1][2]

Sorry for that!
