Are there any behavior changes between

1.2.1

and 1.3.0-RC2` that we need to be worried about? Especially for `@ExperimentalApi`s?

@zak.taccardi

1.2.2

doesn't exist. If you update from

1.2.1

, as long as you didn't use

@FlowPreview

, there should be nothing to do.

Does `ProducerScope`’s behavior change?

ProducerScope

doesn't appear in the changelog: https://github.com/Kotlin/kotlinx.coroutines/blob/master/CHANGES.md

awaitOnClose()

is now available but it's not required.
