Spec Differences

Undeprecated Features

In addition to extensions beyond the specification, RabbitMQ also undeprecates some features that were removed from AMQP 0-9-1.

The access class was deprecated from AMQP 0-9-1. RabbitMQ implements the access.request method from this class as a no-op in order to maintain compatibility with older clients. This method will be removed in the future and should not be relied upon.

amq.* Exchange Immutability

AMQP 0-9-1 spec dictates that it must not be possible to declare an exchange with the amq. prefix. RabbitMQ also prohibits deletion of such exchanges.
