This blog post outlines ten advantages of AMQP 1.0 flow control over AMQP 0.9.1, supported by two benchmarks demonstrating significant performance gains. Additionally, we delve into the powerful AMQP 1.0 flow control primitives and how they are used in RabbitMQ.

RabbitMQ 4.0 (currently in beta) includes new quorum queue features:

• message priorities
• consumer priorities combined with Single Active Consumer
• default delivery limit is now 20 (breaking change!)
• faster recovery of long queues

This blog post demonstrates that native AMQP 1.0 in RabbitMQ 4.0 provides significant performance and scalability improvements compared to AMQP 1.0 in RabbitMQ 3.13.

Additionally, this blog post suggests that AMQP 1.0 can perform slightly better than AMQP 0.9.1 in RabbitMQ 4.0.

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.
