Google has confirmed the rumors of a Panda refresh happening over the weekend.
Google said this refresh started rolling out on Friday, June 8th and has an impact of less than 1% of search queries in the U.S. and about 1% worldwide.
As I said, the search forums took notice to major changes in the search results, specifically impacting sites that were originally hit by the Panda update. I reached out to Google this morning for a confirmation and they have confirmed the update.
Previously, Google pushed out Panda 3.6 on April 27th, about 6 weeks before this update. Google tends to do Panda and even Penguin refreshes every one to two months.
