Hmm I didn't get mine automatically but I went to the Help > About Google Chrome section and saw that it's perched for me to close the browser so I guess I should probably do that now.

Hopefully I won't regret it.
edit: Okay just updated, already noticing a few changes (the settings dropdown thing is 3 circles instead of 3 lines, the pinned tabs have different pictures, the X/refresh buttons changed, etc.) Can't complain about anything so far.
