Which RabbitMQ book to read?

Question

Books

The java project I'm currently working on uses RabbitMQ. While I had to deal with it at the copy-paste level - add a new type of message in one place, process it in another. I would like to understand how it happens inside. Especially since I haven't worked with queue brokers before.
I started reading the book RabbitMQ in Action, the beginning is clear. But it's a little worrisome that the book is from 2012 - it's unlikely that the basic principles have changed, but still even the major version has increased.
What do you recommend to read? Maybe you can recommend videos or competent online courses?
