This is version 9.0 of the Facebook Graph API which includes updates that require developer action in order to ensure that production applications are not interrupted. The Facebook Graph API provides searchable data about content objects on Facebook and the connections between them. This includes people, their friend relationships, shared content, comments, places, events, photos, groups pages, milestones, videos, live video, WhatsApp connections, and others. Public information can be accessed without a developer key/application key, but is required for private data access. Facebook Developers provide services that help build, grow and monetize applications.
