Unsure what major features are missing that you might be clamoring for. A lot of the changes are under the hood sort of things, rather than in your face flashy things.

Latest Office Updates for Windows
Windws 10 x64 is Offering me 4 Office 2010 updates: KB2553347, 4011188, 4011055, 2553338.
The catch is, I don't have Office 2010 installed.
I have been running Office 2016 (via Office 365) since it was released.
