This is a very minor issue and I really don't know how many people it affects, but I thought I would mention it. I have a scheduled task to issue a command stop at 1:00 AM (wife likes to fall asleep with the TV on, so I used the TV's timer to shut it off and a scheduled task to stop whatever she is watching). Anyway, I used the MC16.exe /CommandStop to do this. However, after the upgrade, the Scheduled task was still using MC16.exe to instead of MC17.exe. I technically don't consider this a bug because it did exactly what I programmed it to do (use MC16.exe), but it is something I noticed that I thought people may want to look out for.
