On behalf of the team and everyone who contributed, I am pleased to announce the first Release Candidate for Spring AMQP 3.2 generation.

Some highlights of this release:

• The server side retry logic (manual DLX) has been improved for a new retry-count header to make Spring AMQP compatible with recently released RabbitMQ 4.0.x. The MessageProperties.incrementRetryCount() has to be called before re-publishing message to DLX. The previous logic based on the x-death header does not work anymore since RabbitMQ 4.0.x ignored any x-* headers sent from the client;
• More Open Telemetry semantic tags are exposed via Rabbit Listener and Template observations;
• Some bugs and internal code improvement.
…

On behalf of the team and everyone who contributed, I am pleased to announce the third Milestone for Spring AMQP 3.2 generation.

Some highlights of this release:
