NEW??? AC Delco oil filters

I have been using the AC Delco PH35 oil filter for many years now and recently went to purchase a new case of filters only to find the NEW??? Ph35 filter to be blue instead of white and they certainly appear from the outside to be much lighter and cheaper built. I have not cut one open and did not buy these NEW??? ones as I found a case of old stock filters and purchased them instead. I have been told by one dealer they are the same as the old just a new supplier and yet another dealer said they are not at all the same as the old and are from a different supplier and not sure if this is temporary or a long term change. Can anyone share info they have as to what is really going on? Also one of my local GM parts managers called me asking if I knew anything about a PH35"L" filter he found in his listings. It is referred to as a high efficiency filter and retail list prices at $29.00 Cdn. Just what is a high efficiency filter? Is this the General's version of the Moroso oil filter?
