A notice did appear on the New.FamilySearch.org website (this may be what they mean by an introduction) directing users to "Try FamilySearch Family Tree!" This is one of the major waypoints in the introduction process, letting current users of New.FamilySearch.org about the existence of the program. It would be interesting to see if this link, after signing in, takes the person directly to Family Tree without going through the hitherto necessary "invitation" step. If so, this is a big step towards getting the transition to FamilySearch Family Tree in progress.
If you have not previously used Family Tree and have either an LDS or FamilySearch Account, go to New.FamilySearch.org and click on the link, sign in and see what happens. Since I am already registered, I went directly to Family Tree. I am concerned that those who go to Family Tree by this direct route from New.FamilySearch.org will fail to understand where the Family Tree program resides, that is, that it is not New.FamilySearch.org but merely FamilySearch.org.
Because of the "update" of the Reference Manual in the Help Menu (when you are signed on only) I am not sure which features are or are not available at this time. I tried to search for possible duplicates where the same person was obviously shown twice as a child and got no results from the duplicate search. It appears that, at least in some cases, this feature has been removed for the time being.
OK, if you have gotten to this point in the post, you likely know what I am talking about. If not, I suggest going back through several of my previous blog posts on Family Tree. You may also wish to view the items in the Help Menu on FamilySearch.org concerning the program.
