General Changes
The MessageHistory header is now mutable, append-only container.
And all the subsequent tracks don’t create new message - only their entry is added to existing message history header.
See Message History Chapter for more information.
All the MessageChannel implementations based on the UnicastingDispatcher now can be configured with a Predicate<Exception> failoverStrategy for dynamic decision for the failover on the exception thrown from the current MessageHandler.
See Message Channel Configuration for more information.
