The only noticeable change I have seen is the PCB amount of less than 45ppb (1/2 of the CRN maximum). OmegaRX has it at 10ppb ([i:dc043ba3f1]Page 75, OmegaRX[/i:dc043ba3f1])
Preliminary results on smaller batch testing yielded the standards published in OmegaRX.
Once full scale production began, consistent PCB levels could be achieved at less than 45ppb.
