Linus explained of the 4.6 merge window, "this has actually been one of the bigger merge windows in a while, and if somebody was planning on trying to sneak in any last-minute features, I really don't want to hear about it any more. On the whole, despite the size of the merge window, this was mostly pretty pain-free. There were fairly few conflicts, and the ARM tree that traditionally has had the most of them was really one of the easiest experiences ever. Good job."
You can read more via the release announcement. If you're reading Phoronix daily, hopefully you saw my dozens of articles over the past two weeks otherwise I will have my Linux 4.6 feature overview coming up in the next few minutes with more information.
Update: See our extensive feature overview of Linux 4.6.
