• Add support for image = client.image(filename='./my.jpg'). (Add loading image from filename. #2778, Add filename parameter to client image proxy. #2792)
• Make public method for multiple annotation detection(Add image.detect() for detecting multiple types. #2770).
• Move emotion attributes directly to face. face.joy instead of face.emotions.joy. (Move emotions to Face class. #2782)
