It happened about two months ago. It was around the time they finally dumped giveanything.com (who never got around to sending out rewards) and took over all rewards mailing themselves. They credited all accounts that had redeemed after a certain date in July (can't remember when). They also raised the cashout levels but they credited those accounts with an equivalent number of points needed to get the same reward. No advance warning, They just did it. That's the way a lot of rewards programs work.
