Does anyone know what the exact difference is between the 'original' and '2016 MQA remastered versions of the Mariane Thorsen Mozart Violin Concertos is on the 2L test bench?

E.g., there are two versions of the MQA and 16/44 file, one original and one 2016 MQA remaster, but what's the difference, what process was used in the newer file? Is it that the mastering engineer was able to listen to the MQA output while mastering in the latter, etc?

Thanks.
