• The route models (definition classes) preserve property placeholders, which allows round trip editing, and also prevents showing potential sensitive information
• Added onPrepareFailure option to Dead Letter Channel to allow a custom processor to prepare the Exchange before sending to the dead letter queue.
• MongoDB tailable consumers now allow setting the readPreference option.
• Using setFaultBody / setFaultHeader behaves similar to setBody / setHeader to preserve existing headers/attachments by setting on existing IN or OUT message.
• Java DSL using choice with end vs endChoice now validates you use them as intended. Any misconfiguration now throws an exception explaining the problem.
• POJO Producing and POJO Consuming lifecycle is now in sync with CamelContext which ensures it works as similar to Camel Routes does. Also the created producer/consumer is stopped when CamelContext is stopping to cleanup properly.
• JMS component now allows configuring concurrentConsumers/maxConcurrentConsumers separately between from(jms) vs to(jms) using request/reply over JMS

Fixed the following issues:

...

• camel-boom - For mapping POJO to/from json
• camel-paho - For MQTT messaging using Eclipse Paho client
