There have been a few articles about the new exploit protections in Android 4.1. The Duo Security blog has a great write-up on all the security Google added.

My wife recently switched employers and is now a teacher at a nearby university. She's practiced her line of work for the past six or so years and has done an amazing job honing her skills. She now hopes to pass her skills and techniques on to fellow students of massage therapy. Until just a couple days ago when she landed the job, my wife and I shared a single laptop (a MacBook Pro).
