Emergency mitigation this morning - something about client updates

Emergency mitigation this morning - something about client updates

Did anyone else get a yellow banner when they signed into Endpoint Central this AM ?!?!    I should have paid more attention.  it was something about clients updating,  it was pushed via the Emergency mitigation service.   there was a button to Restart services.  I did.   
I  just want some more information about this fix.  we are on version: 10.1.2228.26, it's the latest I think.

thanks
