Annotation Interface Evolving
Signifies that the annotated program element is subject to incompatible changes by means of adding abstract methods. This, in turn, means that implementing interfaces or extending classes annotated with
Evolvingbears the risk of doing extra work during upgrades. Using such program elements is no different from using ordinary unannotated program elements. Note that the presence of this annotation implies nothing about the quality or performance of the API in question.
