Pure speculation: maybe you get lossy compressed 14 bit output now, instead of the lossy 11 bit? Personally I prefer lossless compression over totally uncompressed to save on a bit of storage space.

 

Edit: reading the interview at image-resource does imply it is now 14 bit lossy compressed. So more bit depth, but still lossy.

I don't think this is different. It was always lossy compression of 14 bit. I think you have got the 11 bit from the description of the compression scheme as "11+7"  (except in some modes like fast continuous where it reduced to lossy compressed 12 bit)

 

Having said that, while in exceptional circs there are sometimes artefacts, their compression scheme is damn good, and effects in IQ are extremely rare, even with radical shadow boosting...
