RabbitMQ 3.11.26 is a maintenance release in the 3.11.x release series.

This release series is no longer covered by community support.

Please refer to the upgrade section from v3.11.0 release notes if upgrading from a version prior to 3.11.0.

This release requires Erlang 25 and supports Erlang versions up to 25.3.x. RabbitMQ and Erlang/OTP Compatibility Matrix has more details on Erlang version requirements for RabbitMQ.

Minimum Supported Erlang Version

As of 3.11.0, RabbitMQ requires Erlang 25. Nodes will fail to start on older Erlang releases.

Erlang 25 as our new baseline means much improved performance on ARM64 architectures, profiling with flame graphs across all architectures, and the most recent TLS 1.3 implementation available to all RabbitMQ 3.11 users.
