From circa 2005 through 2008, Ancestry.com gave away and/or sold a couple of "special editions" of GenSmarts. These editions, called either "GenSmarts for MyFamily.com" or "GenSmarts for Family Tree Maker" were subsets of the full product and sold exclusively by Ancestry.com and only available on CD. These "special editions" were discontinued at that time (2008), though we continued to provide support and updates for them into 2012. The last update for those products can be downloaded at the links below.
Last Version 1 Special Edition update released (March, 2012): (GenSmarts For MyFamily.com)
Last Version 2 Special Edition update (March, 2012): (GenSmarts For FamilyTreeMaker)
The full edition of the product, of course, continues to work with Ancestry.com and Family Tree Maker, as it always has. Users of the special edition who want to the latest updates would need to purchase the current full edition of the product.
