3.10.12

RabbitMQ 3.10.12 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

Core Server

Enhancements

• Quorum queues are now more resilient to WAL log growth with workloads that involve clients that register a consumer and then close the channel or connection without ever consuming any deliveries or cancelling the consumer.

  GitHub issue: #6447

Bug Fixes

• When a node encouters an invalid definitions.local.file on boot, it will refuse to start instead of ignoring the file.

  GitHub issue: #2610

• Fixed a type analyzer definition.

  GitHub issue: #6401

CLI Tools

Enhancements

• Queue info keys now support more inclusive property names related to (deprecated) classic mirrored queues. For example, mirror_pids can now be used instead of slave_pids.

  Contributed by @illotum (AWS).

  GitHub issue: #2635

• rabbitmq-diagnostics memory_breakdown now executes significantly faster in environments with a large number (say, tens or hundreds of thousands) of quorum queues. Two orders of magnitude faster, in fact.

  GitHub issue: #6388

Bug Fixes

• Definition export in JSON failed on nodes that used definitions.skip_if_unchanged.

  GitHub issue: #6424

• Using quorum queue-specific commands on streams now results in clearer error messages.

  Contributed by @gomoripeti (CloudAMQP).

  GitHub issue: #6488

LDAP Plugin

Bug Fixes

• LDAP server password could end up in the logs in certain types of exceptions.

  Contributed by @SimonUnge (AWS).

  GitHub issue: #4842

STOMP Plugin

Enhancements

• x-max-age stream setting now can be set by STOMP clients via a header.

  GitHub issue: #5003
