public @interface Beta
Signifies that a public API (public class, method or field) is subject to
incompatible changes, or even removal, in a future release. An API bearing
this annotation is exempt from any compatibility guarantees made by its
containing library. Note that the presence of this annotation implies nothing
about the quality or performance of the API in question, only the fact that
it is not "API-frozen."
