What's the difference between dlnetwork and DAGNetwork about deep learning?

In deep learning toolbox, there are dlnetwork and DAGNetwork object. But I want to know what's the difference between them?

DAGNetwork was the object created when the Deep Learning Toolbox first started supporting CNNs and LSTMs. A few years after dlnetwork came out, to support customized networks like GANs. In the future you will likely see more support for dlnetwork training and inference in MATLAB as it will help us support a larger variety of network types.
