I've used this for a while and it's interesting to see that the version numbers have gone from 3.4.1 straight to 4.0.b5 overnight. It sounds like they are trying to cash in and make users pay for a version increase which is in fact still beta (why not implement the upgrade fee when it's out of beta???).

I can't really see much extra functionality that i'd use for the money between 3.4 & 4.0 so for the time being i'll be sticking with the older version which works just fine.

I'm all for paying for upgrade's within reason, but give me something substantial for my money else i'm going to start looking elsewhere.
