Many of these features will be launching over the next few months. You can read more about these on the Official Google Blog.
We also have an updated program policy that covers data usage related to the launch of these new features.
We hope these features will help you meet your ROI goals by concentrating your ad impressions on the best inventory at the most relevant time and by helping you more effectively manage your campaigns on the Google content network. We're excited about delivering these enhancements while preserving user privacy, and we'll be sure to provide you more info on all of these features as we begin to roll them out in the next few months.
