• Breaking change: the channel.publish() method no longer returns a DeferredPublisher-object, because it was not logical that you had to reinstall the callbacks for bounce-methods after each individual publish() call, not was it logical that the callbacks were not always logically linked to the publish() operation that failed (they were always sent to the handler of the most recent publish() instead of to the handler of the failed publish()). At the same time we added a channel.recall() method that can be used to notify the library that user-space is prepared to recall/take-back/accept bounced messages
• Renamed DeferredConfirmedPublish to DeferredPublish
