RabbitMQ 3.11.19 is a maintenance release in the 3.11.x release series.

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.

Changes Worth Mentioning

Release notes can be found on GitHub at rabbitmq-server/release-notes.

Core Server

Bug Fixes

  • Declaration of a classic queue could run into an exception.

    GitHub issue: #8629

  • Nodes that had a large number of quorum queues could observe accumulation of Erlang processes under significant load. A follow-up change to #7389.

    GitHub issue: #8591

  • Feature flag discovery operations will now be retried multiple times in case of network failures.

    GitHub issue: #8491

  • Feature flag discovery on a newly added node could discover an incomplete inventory of feature flags.

    GitHub issue: #8487

  • Nodes in clusters that had quorum queues and non-mirrored classic queues on stopped (or failed) nodes could run into an exception.

    The same exception could affect rabbitmqctl list_queues.

    GitHub issue: #8596

  • Proxy Protocol v2 LOCAL packets were not supported.

    GitHub issue: #8668

Enhancements

  • When a quorum queue does not find its local replica data files on boot, it will now log a warning.

    GitHub issue: #8630

Management Plugin

Bug Fixes

  • An attempt to clear limits of a non-existent virtual host failed with a 500 status code.

    GitHub issue: #8523

Enhacements

  • Management UI will now display node maintenance status.

    Contributed by @SimonUnge (AWS).

    GitHub issue: #8558

  • The "Queues" tab in the UI was renamed to "Queue and Streams" to better reflect its contents.

    GitHub issue: #8520

  • New HTTP API endpoints for quorum queue replica management, equivalent to the rabbitmq-queues commands that manage replicas.

    POST /api/queues/quorum/{vhost}/{name}/replicas/add
DELETE /api/queues/quorum/{vhost}/{name}/replicas/remove
POST /api/queues/quorum/replicas/on/{node}/grow
DELETE /api/queues/quorum/replicas/on/{node}/shrink

    GitHub issue: #8561

Stream Plugin

Bug Fixes

  • Stream client connections that authenticated using x.509 certificates failed.

    GitHub issue: #8488

OAuth 2 Plugin

Bug Fixes

  • Only set OAuth 2 client's CA certificate file setting when it is defined.

    GitHub issue: #8548

Enhancements

  • The plugin will now accept JWT tokens without a scope. Such tokens would only be useful when the plugin is used exclusively for authentication and not authorization.

    GitHub issue: #8391

  • oauth2 is now an accepted alias for the OAuth 2 authentication and authorization backend:

    auth_backends.1 = oauth2

    Previously the only option for OAuth 2 was using a full module name, rabbit_auth_backend_oauth2.

    GitHub issue: #8513

STOMP Plugin

Bug Fixes

  • STOMP plugin log entries had an extra line feed character.

    GitHub issue: #2568
