3.10.11

RabbitMQ 3.10.11 is a maintenance release in the 3.10.x release series.

Please refer to the upgrade section from v3.10.0 release notes if upgrading from a version prior to 3.10.0.

This release requires Erlang 24.2 and supports Erlang 25. RabbitMQ and Erlang/OTP Compatibility Matrix has more details on Erlang version requirements for RabbitMQ.

Minimum Supported Erlang Version

Erlang 23 support has reached its end of support.

This release of RabbitMQ requires Erlang 24.2 or later versions. Nodes will fail to start on older Erlang releases.

Erlang 25 is recommended: it offers much improved performance on ARM64 architectures, profiling with flame graphs across all architectures, and the most recent TLS 1.3 implementation.

Changes Worth Mentioning

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

Core Server

Bug Fixes

• Stream unsubscription leaked metric counters.

  GitHub issue: #6325

Enhancements

• Quorum queue replicas no longer try to contact their unreachable peers for metrics. Previously this could result in a 30-40s delay for certain HTTP API requests that list queue metrics if one or more cluster members were down or stopped.

  GitHub issues: #6282, #6285

CLI Tools

Bug Fixes

• rabbitmq-diagnostics status now handles server responses where free disk space is not yet computed. This is the case with nodes early in the boot process.

  GitHub issue: #6303

• When a plugin was enabled as a dependency (e.g. rabbitmq_shovel as a dependency of rabbitmq_shovel_management), CLI tools previously did not discover commands in such plugins. Only explicitly enabled or pre-configured plugins were scanned for commands.

  This behavior was confusing. Now all enabled (explicitly or as a dependency) plugins are scanned.

  GitHub issue: #6020

Stream Plugin

Bug Fixes

• Addition of a stream member could fail if the node being added was very early in its boot process (and doesn't have a certain stream-related components started).

  GitHub issue: #6182

AMQP 1.0 Plugin

Enhancements

• Support for "modified" disposition outcome used by some client libraries (such as QPid).

  GitHub issue: #6243

Management Plugin

Bug Fixes

• Management UI links now include "noopener" and "noreferrer" attributes to protect them against reverse tabnabbing. Note that since management UI only includes a small number of external links to trusted resources, reverse tabnabbing is unlikely to affect most users. However, it can show up in security scanner results and become an issue in environments where a modified version of RabbitMQ is offered as a service.

  GitHub issue: #6211

Shovel Plugin

Bug Fixes

• Plugin could stop in environments where no static Shovels were defined and a specific sequence of events happens at the same time.

  Contributed by @gomoripeti.

  GitHub issue: #6286

Windows Installer

Bug Fixes

• When installation directory was overridden, the plugins directory did not respect the updated base installation path.

  GitHub issue: rabbitmq/rabbitmq-packaging#29
