Lots of under-the-hood updates (preparing for L release) as well as fixes. Kindly test on all your devices and Android versions again. Some heavy SELinux hacking is going on, so behavior between <4.2, 4.2, 4.3, 4.4, L, and latest AOSP builds may differ. Sooner we find the issues there the better, hoping for a Play release over the next few days if not too significant issues are found (which of course, there will be)
