1) The version number update was issued to keep all three products in sync with some common changes.
2) PhotoPost has matured over three plus years of development. Classifieds has come a long way in a few months - to suggest it hasn't come far enough is almost an insult to the time that has been spent getting it where it is.
3) Classifieds as it is makes for a great addition to any site - the level of integration is a first for this kind of script. Many of the just-added features of PhotoPost (including signatures, avatars and style integration) have been added to this very new product.
Like PhotoPost, Classifieds will continue to grow and improve - the changes in just the past few months have themselves been significant and I see no reason to think it wont continue.
