Points of interest: If someone tweets from a specific place, users will be able to see the place and other tweets from the same location. Think of this like “twecking in”.
Promoted tweets: Paid tweets that will appear at the top of Twitter’s search results for specific queries.
Annotations: This will allow developers to “add any arbitrary metadata to any tweet in the system.”
