New Google Play Content Policy

I saw this when I was registering new developer account. From 23.august users must comply with new content policy or delete their apps. And they placed this link:

https://support.google.com/googleplay/android-developer/answer/3311168

Does anyone know what’s new in all this? What ads behavior??
