I was checking my Google app for upgrades and a newer version was available. I had version 3.3.38 which was out around 8 weeks ago. I have not seen any changes as of yet, I even checked the web for some sort of change log, but no such luck. If anyone upgrades and notices something new between versions please let us know by comment.
The upgrade went flawless, and uninstalled the older version by prompt automatically. It did require a restart after the install by prompt also. When opening the new installation it completed the install which was very quick.
