There is one awesome new feature that is not mentioned on most "best new features" list: built-in night mode (blue light filter). Works much better than similar apps from the store - those work by placing a translucent overlay window on top of everything else, which gives everything (including black!) a reddish hue. The new built-in filter, on the other hand, just removes blue, and blacks remain black.

Unfortunately, it doesn't appear that this made it into the final version of N. I can't find it anywhere in the settings anyway.
So apparently what happened is that they left the code in, but removed the switch in System UI Turner. So those who were in the beta program, installed preview builds, and enabled the feature, still have it enabled after upgrading to 7.0 final. But if you didn't have it enabled before, there's no way to do so out of the box.

However, there's a third party app that provides access to the switch (seems to not work for some people, or require several tries - YMMV): http://android.wonderhowto.com/how-to/enable-hidden-night-mo...

It's on my 6p which had an updated this morning that I assume was N final (I've been running the betas). It's in the dropdown settings pane. You might need to hit "EDIT" and add it as a tile?
I have updated my 6P to final, and it's still there. You might still need to jump through "experimental feature" hoops to enable it though - I haven't checked, but you had to do so in the last preview build.
I don't think the blue light filter made it into the final release
As in it's available without root? Because this has been available with root since KitKat, and there were also some apps which allowed you to use it...
I didn't know about this and now I am really interested in the update. I've been using one of the overlay ones for a while and it is kind of annoying.
I just upgraded to Android 7.0. Night Mode is still there! You can access it by enabling the system UI tuner.

Just swipe down from the top of the screen to reveal the quick settings, and then press and hold the Settings icon (gear) for a few seconds and release. This will enable the UI tuner.

Swipe down from the top again, then tap "EDIT" in the bottom right corner. There should be a tile for "Night mode", which you can drag and drop into the quick settings panel for easy toggling.

Did you upgrade from DP5?
I didn't and I can confirm the feature isn't there in a 6->7 update.
I can't find it, I searched settings for 'blue, 'bed' & 'night'.
