RabbitMQ 3.10 has recently been released and has some major new features which focus on optimizations, performance, and stability.

Release notes page includes information about the specific changes in this version as well as various installation assets. See our upgrade guide for more information about upgrading to 3.10.0.

Let’s have a tour!

RabbitMQ RPM packages for CentOS 7 will be discontinued from May 2022 because that CentOS release series provides outdated versions of OpenSSL and Linux kernel.

CentOS 7 users are recommended to migrate to a new cluster which uses a more recent distribution via one of the options:

• In-place Upgrades
• definition transfer
• Blue-Green Deployment upgrade.

Quorum queues in RabbitMQ 3.10 provide a safer form of dead lettering that uses at-least-once guarantees for the message transfer between queues. This blog post explains everything you need to know to start using at-least-once dead lettering.

This post also introduces two other RabbitMQ 3.10 features: message Time-To-Live (TTL) for quorum queues and Prometheus metrics for dead lettered messages.

We intend to release RabbitMQ 3.10.0 on 11 April 2022. While we have been testing it internally for some time, with production-like workloads, we need your help to check that it is as stable and reliable as we believe it is.

Many organizations have policies around RabbitMQ usage wich they would like to enforce. This blog post explains via example how the Open Policy Agent Gatekeeper project can be used in combination with the RabbitMQ Messaging Topology Operator to manage RabbitMQ resources on Kubernetes and enforce policies on those resources by extending the Kubernetes API.
