+### New Quality Attribute in Detection_01 and Detection_03
+* To help system builders and their customers capture high quality images which are necessary for high quality outputs from Face API, we’re introducing a new quality attribute **QualityForRecognition** to help decide whether an image is of sufficient quality to attempt face recognition. The value is an informal rating of low, medium, or high. The new attribute is only available when using any combinations of detection models `detection_01` or `detection_03`, and recognition models `recognition_03` or `recognition_04`. Only "high" quality images are recommended for person enrollment and quality above "medium" is recommended for identification scenarios. To learn more about the new quality attribute, see [Face detection and attributes](concepts/face-detection.md) and see how to use it with [QuickStart](https://docs.microsoft.com/azure/cognitive-services/face/quickstarts/client-libraries?tabs=visual-studio&pivots=programming-language-csharp).
