you might need to wait after servicebus June release (amqp released, but servicebus is not yet).

[weidongxu-microsoft]

I think servicebus is released, you might want to refresh main and get it merged before next code freeze.

Any reason for why we change the name from SERVICE_BUS_MESSAGE_STATE_KEY to SERVICE_BUS_MESSAGE_STATE_ANNOTATION_NAME?

Since we move it into amqp, is it ok to remove SERVICE_BUS prefix?

[ZejiaJiang]

Yeah, the above keys have ANNOTATION_NAME suffix as well and we do get the key from annotation.

I'll check these keys usage and remove the prefix.

[JimSuplizio]

The creation and use of the unreleased_ tag was done correctly and I'm okay with those changes. I'll let the other people review and approve the corresponding code changes.
