    Maybe you can find out more about Microsoft's development/release 
process for MRO and why they're still on 4.0.2 (from June 2020)?  I 
followed the "user forum" link on their web page, but it appears to be a 
generic Windows forum ...


    I might tweet at @revodavid (David Smith) to see if there's any more 
information available about the MRO release schedule ...

   good luck,
    Ben Bolker
