@Marc Stridgen I apologize for getting involved in this topic, but maybe there really is some problem with auto upgrade...
Here's what happened to me - when I received an email that you activated 4.7.16, I, as usual, logged into my test installation - I started autoupgrade and it went perfectly (but note that in this installation I already have the 4.7.16 beta update) .
So far so good - but when I started a live site with the same intention to update, I was startled for a moment - because it turned out that the live site is also already with 4.7.16 - ie. for some reason when updating my test installation, the live site was also updated...
I.e. there is some mystery in your new release.
Again, I apologize for writing in this thread, but I thought this information would be useful to you.
Also - with many updates, the changed templates check returned nothing, even though there are important templates with changes from your original development.
