New access permissions for Google Maps v9.1.1
I agree, I see no obvious reason for these permissions to be added based on the change log.  

Yes I can invent some reasons that maybe it "needs" them for one feature or another (clicking restaurant near you and calling from the app directly).

But the point here is that there is no explanation. It is dead wrong for Google to behave this way, as it causes behaviour of "default acceptance" in all future cases. Including non Google ones.

Just like the windows pop-ups...  this application is asking for "internet"...  you have no choice but to say yes, and frankly no way to find out why.

Now, today, you are basically as secure as if there were no permissions at all. Every app needs everything, and everyone just clicks yes.

Well done to everyone.
