Chris Walsh has already broken down the files in the 7392 May Security update that is starting to roll out today. What's interesting is besides those SSL certificates, there's a whole bunch of other files that have been updated that seem to imply.

Now, we should point out that this update is cumulative--meaning it also includes the past NoDo updates, etc. But at least according to Walsh (via Twitter), the files in this cab are different from 7390--meaning these are newer ergo Post-NoDo. Russell Clark from Microsoft though disagrees (via Twitter). What exactly they all do, we're not sure yet, but Walsh promises to break them down over the next few days to find out.  Till then, here's the list of reportedly changed files from 7390:

Managed Assembly Updates (IL diff changes to come)

  • Microsoft.Phone.Interop
  • Microsoft.Phone.InteropServices
  • Microsoft.Phone.MediaExtended
  • Microsoft.Phone.Reactive
  • Microsoft.Phone
  • System.Observable
  • Microsoft.Device.Sensors
  • System.Device (location sensors)
  • Microsoft.Xna.Framework.Game
  • Microsoft.Xna.Framework.GamerServices
  • Microsoft.Xna.Framework.Graphics
  • Microsoft.Xna.Framework.Input.Touch
  • Microsoft.Xna.Framework

AvCore (Camera Operations)

  • Quartz.dll

We'll follow up on this as it develops.
