Google rolled out a Panda update late on Friday. Google announced the update on twitter saying:
Panda refresh rolling out now. Only ~1.6% of queries noticeably affected.
Looking into the wording on this tweet, we can learn a few things:
(1) 1.6% of the search queries were effected, which is small but large for those hit.
(2) This is specifically a "refresh" and thus it seems like no new signals or algorithm changes were made to this Panda update. In short, they simply reran the algorithm on their index.
