RabbitMQ 3.12 will be released soon with many new features and improvements. This blog post focuses on the the performance-related differences. The most important change is that the lazy mode for classic queues is now the standard behavior (more on this below). The new implementation should be even more memory efficient while proving higher throughput and lower latency than both lazy or non-lazy implementations did in earlier versions.

For even better performance, we highly recommend switching to classic queues version 2 (CQv2).

RabbitMQ now has an official Discord server started by the core team. If you prefer Discord to Slack, feel free to join it and discuss all things RabbitMQ!

We intend to release RabbitMQ 3.11.0 on 5 September 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.

RabbitMQ 3.10 was released on the 3rd of May 2022, with many new features and improvements. This blog post gives an overview of the performance improvements in that release. Long story short, you can expect higher throughput, lower latency and faster node startups, especially with large definitions files imported on startup.

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!

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.

RabbitMQ is not affected by the Log4j vulnerability, read below for more details.

In RabbitMQ 4.0, we intend to remove some RabbitMQ features to:

• Increase the resiliency of the core broker
• Decrease the number of suboptimal configurations available
• Remove technical surface area (maintaining old code) from the team
• Reduce the support burden

We continually innovate to meet and exceed our users’ expectations. Removal of older functionality that no longer meets these expectations, or serves our users, means we can focus on our mission to provide a stable, performant, and flexible messaging system.

We intend to release RabbitMQ 3.9.0 on 26 July 2021. While we have been testing it internally for months, with production-like workloads, we need your help to check that it is as stable and reliable as we believe it is.
