Ancestry v2
From SNPedia
This chip appears to have begun being used by AncestryDNA starting in (late) May 2016, replacing the V1.0 chip.
The V2.0 chip results in Promethease reports that have ~three-fold more information than the V1.0 reports (as of May 2016, about 47,000 genotypes instead of 13,000).
