Team RabbitMQ has two updates related to our Debian and RPM repositories:

1. On August 18, 2024, Team RabbitMQ's PackageCloud account will be discontinued
2. Cloudsmith mirror repositories now use *.rabbitmq.com domains, please update your repository definition files

We are pleased to announce that RabbitMQ 4.0 supports AMQP 1.0 as a core protocol, providing the following benefits:

• Modernized RabbitMQ to natively support the latest AMQP standard
• Support for more AMQP 1.0 features
• Significantly better AMQP 1.0 performance and scalability compared to RabbitMQ 3.13
• Greater interoperability with other AMQP 1.0 message brokers
• AMQP 1.0 is enabled by default in RabbitMQ 4.0

Effective June 1st, the RabbitMQ community support and release policies will change for the open source distributions of RabbitMQ. The goal of these changes is to ensure that the RabbitMQ team has time to focus on developing new features for the Open Source and commercial versions of RabbitMQ.

Erlang/OTP 27.0 was released on May 20th, 2024. While it contains a lot of exciting features and improvements, unfortunately RabbitMQ currently doesn't work well with this version.

RabbitMQ 3.13 is now available with support for MQTTv5, stream filtering and significant improvements to classic queue performance, especially for larger messages.

Read dedicated blog posts for more details about these changes:

• support for version 5 of the MQTT protocol
• support for stream filtering
• performance improvements

RabbitMQ 3.13 is the final minor release in the 3.x series. The next release will be 4.0!

We've already announced two major new features of 3.13 in separate blog posts:

• support for version 5 of the MQTT protocol
• support for stream filtering

This post focuses on the changes to the classic queues in this release:

• classic queue storage format version 1 is deprecated
• new implementation of the classic queue message store

We have been working for several weeks on a new website for RabbitMQ. We plan to release this significant upgrade shortly after RabbitMQ 3.13.0 is released! At this point, we would love you to visit the new website and tell us what you think :-)

In this blog post, I will go over the reasons we are doing this and what improvements it will bring to you.

A previous post gave an introduction to stream filtering, a new and exciting feature in RabbitMQ 3.13. In this post we cover the internals of stream filtering. Knowing the design and implementation will help you to configure and use stream filtering in the most optimal way for your use cases.

Stream filtering is a new feature in RabbitMQ 3.13. It allows to save bandwidth between the broker and consuming applications when those applications need only a subset of the messages of a stream.

Keep reading to find out how stream filtering works and see it in action.

Native MQTT released in RabbitMQ 3.12 has delivered substantial scalability and performance improvements for IoT use cases.

RabbitMQ 3.13 will support MQTT 5.0 and will therefore be the next big step in our journey to make RabbitMQ one of the leading MQTT brokers.

This blog post explains how the new MQTT 5.0 features are used in RabbitMQ.
