API sets on the v1.0 endpoint (https://graph.microsoft.com/v1.0) are in general availability (GA) status, and have gone through a rigorous review-and-feedback process with customers to meet practical, production needs. Updates to APIs on this endpoint are additive in nature and do not break existing app scenarios.
