According to some reports, the following items have been rolled out to some individuals and should be rolled out to all AncestryDNA testers at some point:
Sort by relationship level
The ability to create and modify groups
Filter by contact status
Other options that haven’t been reported yet.
I don’t know how new one option I found today is, but sort by Regions is something I haven’t seen before. It is only four (4) regions or migration choices, but those appear to be based on my mother’s line for half and my father’s line for the other half. That’s based on the two distinct locations – Mississippi / Louisiana, and North Carolina.
I will update once I either gain the new stuff or somebody provides more details.
