I believe Norm is correct, the rumor is Purolator acquired another manufacturer and set up manufacturing in a new facility. They make filters for multiple brands including Bosch and some components like end plates may be shared. The design change to outie has left insufficient room to seat the gasket fully.
I measured a few of the previous filters and they were .24" or more gasket surface to where the "nut" might hit. The "outies" have less. Next oil change I'll measure gasket surface to nut for fun, unless someone has already done so.
