Annie Babcock at Deloitte recently sent out an email showing dates of cut-over to a new format for MSIX submissions. I've gotten several emails about this so I wanted to take a moment and let everyone know - You're Covered!

We implemented support for this change months ago. It was originally supposed to go into effect 8/1/2016 but the MSIX team delayed it. The bottom line is that there's nothing for any MIS2000 state to do. We'll flip a switch on the right day and everything should just work.
