My Nexus 7 (2013) tablet got the OTA upgrade notice on November 10, 2015. It is a big update from Android 5 to Android 6, or from Lollipop to Marshmallow.
It is said new Android 6.0 Marshmallow improved performance, battery life and features.
Since the first announcement at Google I/O on May 28, I wait more than five months to get the OTA update package. The update package size is 334.9MB.
Look at the system update notice.
