     2) Supported customizing service endpoints by assigning the endpoint string to FaceClient.Endpoint. The endpoint string can be found on Azure Portal, it should contain only protocol and hostname, for example: https://westus.api.cognitive.microsoft.com. This change ensures better global coverage.
     3) Aligned with latest Face API, Million-Scale features (LargePersonGroup and LargeFaceList) were added.
