There was some minor changes in the right hand corner as well. Like the fact that they switched places on the company picker and search button (now not a field) is maybe the most prominent change, but they also swapped the help button and feedback.
There is also a nice separator and the messages has lost the alert/bell icon. Quite good as there are no alert feature any more.
