Thanks for the suggestion. Release notes on new versions of FTB is a great idea.
In the past we have notified users by email when a new version of FTB is released. Those emails include new features updates as well.
For your general informaiton here is a list of the features that were included in the last release of the program (FTB4.0)
In Family Tree Builder 4.0 new features include:
Using our maps, you can explore your family’s origins, gain a better knowledge of your family, and enjoy all the benefits below:
Fix place names according to smart suggestions we provide and improve your data
Map your entire family tree, or any portion of it, or just one individual
Map birth places, places of residence, other particular facts, or all facts
See all people, events and photos associated with any particular country or place
See all places of importance in any person’s life, and trace immigration patterns
Find any place in any language on the map
Organize your photos in albums for your convenience. When you publish your family tree to the web, the album structure is preserved in your family site.
This makes it much more convenient to manage very large photo collections. Inside albums, use drag & drop to change the order of photos. Also use drag & drop to copy or move photos between albums. You can even drag photos from Windows into Family Tree Builder in the new version.
Slide shows and screen saver
You can also view slide shows of any photo album that you create or for all photos. In addition, Family Tree Builder now comes with a Screen Saver that shows this slide show for any or all of these albums.
And there are many other smaller but nevertheless important improvements in version 4.0. For example, you can now restore a family tree you published to your family site, including photos.
