The Twitter v2 API is now available in pre-release. It includes functions to specify data fields, plus added objects including mentioned accounts in Tweets, tagged places, quoted and replied-to Tweets, attached media, poll results and pinned Tweets. It also offers public and private Tweet metrics, insights on topics, and improved conversation tracking. This version will replace the standard v1.1, premium v1.1, and enterprise APIs in the future. Specific updated methods include Tweet lookup, recent search, filtered or sampled stream, user lookup and more.
