If this algorithm change has already occurred, it didn't do much. What I see: exact match subdomains moving up, an EMD in my sector with thousands and thousands of foreign backlinks moved down exactly two spots, another that expired 2 months ago moved up.
Edit: I spoke too soon. One of those sites is disappearing right before my eyes, term by term.
