I can only presume that this update was released by Adobe in order to squeeze the last drop of blood ie cash from the loyal Golive users that have used this product over the years.

As well as excluding the product from the CS3 suite Adobe now expect users to pay €200 for an upgrade that only has 2 discernable new features : the new Adobe unified interface and a couple of positioning tools for css divs. Both are welcome additions but hardly worth the insane upgrade price. This really should be a free upgrade to Golive users but it's really part of the overall plan to "force" people into switching to Dreamweaver.
