 This version is the first stable release with [`Flow`](https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.flow/-flow/index.html) API.
 
 All `Flow` API not marked with `@FlowPreview` or `@ExperimentalCoroutinesApi` annotations are stable and here to stay.
-Flow declarations marked with `@ExperimentalCoroutinesApi` have [the same guarantees](/docs/compatibility.md#experimental-api) as regular experimental API.
-Please note that API marked with `@FlowPreview` have [weak guarantees](/docs/compatibility.md#flow-preview-api) on source, binary and semantic compatibility.
