are Channels abandoned and is Flow the future? When Flow was introduced it was a lot of talk about hot channels and cold flows but now it seems that you can run hot flows as well?

[elizarov]

Channels are not abandoned. Moreover, they are critical building blocks on top of which many important flow operators are built.

[elizarov]

However, BroadcastChannel and ConflatedBroadcastChannel will be deprecated in favor of shared flows.

@elizarov will there be quick iteration on these Milestone releases?

[dalewking]

More importantly for me a release that combines SharedFlow with native multithreading

[elizarov]

We are waiting for your feedback to finalize the design.
