From the product page it seems they did some update of Data Assist, however from what i read the update does not sound like a major new release of DataAssist in functionality and all the new wizard functions still point to the same individual extensions like Universal Email, DigitalFile Pro etc etc.
Also if you look that DataAssist individual price is $199, even for a an upgrade of this extension $149.99 is too much in my opinion.
I really hope WA will reconsider their upgrade pricing for SS users as i really would like to purchase it, but for less then this.
