The branch master is the main one, which makes https://github.com/freenowtech/spring-multirabbit lib work on SpringBoot 3.2.x There was a huge change in Spring-AMQP since Spring Boot 3.1.x, so the Spring MultiRabbit was not working anymore. Until now :)
The major change is in in CustomMultiRabbitAutoConfiguration and RabbitMQConnector.
Please help yourself.
