AncestryDNA updating this week

Ancestry is preparing to update its ancestral origins (previously ethnicity estimates) later this week, beginning from Thursday. Along with adding macro-regions (such as Nordic grouping together the Scandinavian countries), decimal percentages instead of rounded percentages similar to MyHeritage, and using a larger reference panel, there are likely other big changes to AncestryDNA.

For the various kits I manage, I am really curious to see what changes from last year's update, and how this compares to similar results with MyHeritage, FTDNA and LivingDNA. I am also waiting to see if new ancestral journeys are added or new sub-regions within countries like Spain and Ireland are added.
