The DNA circles seem to be grouping by subgroups now (for example, by closer to present common ancestor descendant of the farther back ancestor descendant). It's appearing under the name of the DNA tester in the list in a given circle. That seems to be a good change.
The other change is there is now a biography section for the common ancestor up at the top. However, has anyone seen problems with it? For one of my ancestors, it's pulling the correct marriage but also pulled in a brother's marriage, listing it as a second marriage. No one in the circle made that mistake in their trees. The names of the brothers, the marriage dates and locations, and the names of the wives are unique enough that even a computer generated biography should have distinguished it.
