TPS51604: What date did the MSL change from 1 to MSL 2?

Hi 

Where did you find the device is with MSL2?

We have been using it for some time, and now we have received the MSL1 version for the first time, we have received an inquiry from the customer.
We are urgently waiting to confirm when the change will be made.

The datasheet says Level 1
