HUGE update today.

"Feature update to Windows 10, version 1607"

Just updated with a comprehensive download, over 90 minutes to download and install. Changes to Cortana, action center, Windows Ink installed, etc. etc.
Too soon to evaluate fully, but power consumption looks better again.
Here's hoping.

There was a firmware update released on Oct 5th (September Updates for Surface Pro 4, Surface Book, and Surface 3) but I have yet to see it when I check for updates on my Surface Book.

Has anyone gotten the update yet?
