There is a newer version: 2.1.0-RC

package kotlin

import kotlin.annotation.AnnotationTarget.*

/**
 * This annotation marks the standard library API that is considered experimental and is not subject to the
 * [general compatibility guarantees](https://kotlinlang.org/docs/reference/evolution/components-stability.html) given for the standard library:
 * the behavior of such API may be changed or the API may be removed completely in any further release.
 *
 * > Beware using the annotated API especially if you're developing a library, since your library might become binary incompatible
 * with the future versions of the standard library.
 *
 * Any usage of a declaration annotated with `@ExperimentalStdlibApi` must be accepted either by
 * annotating that usage with the [OptIn] annotation, e.g. `@OptIn(ExperimentalStdlibApi::class)`,
 * or by using the compiler argument `-opt-in=kotlin.ExperimentalStdlibApi`.
