No it didn't. Unless the game updates itself there is no update. Always disable google play automatic updates, they can destroy your game installation (literally)
I don't have Google Play, in fact I don't even have anything remotely Google on my Apple iPad mini. They're called silent updates because the message was sent directly from the game itself without an acknowledgement of an update from an offsite source such as Facebook or Reddit. Every time I get an update message, I check Facebook to confirm it and to see what it's all about. There is usually a server merge attached to an update; this time there isn't.
All I ask is that you please be transparent with your updates. Even if it's a technical issue relating to security or to something trivial like the log-in screen, I'll be okay knowing about the one change ahead of time, and I won't be forced to go through the entire game one feature at a time just to compare versions.
