AOKP Permission Manager?

I am running Paranoid Android and love it, but it is hard on battery life. So I am looking at flashing back to AOKP. In looking around, I've seen some vague references to a "Permission Management" ([such as mentioned here](http://aokp.co/blog/milestone-2-has-finally-arrived)) in the latest AOKP... but after googling for a couple days, can find no real details on it. Is this something that is in the current stable builds of AOKP, or is just referring to the built-in one from Android 4.3 in the latest AOKP nightlies? If anyone can point me to an article with a some good information on this feature and its current build status, I'd be very grateful. Been missing this functionality since LBE Privacy Guard died with Jelly Bean. Mind you, I am aware of other options such as LBE, PDroid, XPrivacy. I'm looking specifically for more information about AOKP's permission management. Thanks!
