RabbitMQ 3.10.16

RabbitMQ 3.10.16 is a maintenance release in the 3.10.x release series.

This series reaches end of general support on July 31st, 2023.

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 24.3 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 and 24 versions older than 24.3 have reached end of support.

This release of RabbitMQ requires Erlang 24.3 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.

CLI Tools

Features

• rabbitmqctl hash_password is a new command that produces a hashed value of the provided password.

  Contributed by @SimonUnge (AWS).

  GitHub issue: #5957

• rabbitmq-diagnostics check_port_connectivity now supports a new optional flag, --address,
  that makes the check connect to a specific IP address instead of resolving node's hostname.
  This is useful when target node is configured to only listen for connections on one interface
  but not others:

  rabbitmq-diagnostics check_port_connectivity --address 127.0.0.1
  rabbitmq-diagnostics check_port_connectivity --address "::1"

  GitHub issue: #6853

  that match a naming pattern:

  default_operator_policies.1.vhost_pattern = ^device
  default_operator_policies.1.queue_pattern = .*
  default_operator_policies.1.max_length_bytes = 1GB

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

Core Server

Enhancements

• Backported a number of improvements for non-ASCII character handling in paths on Windows.

  GitHub issue: #5551

• Backported a number of free disk space monitor resiliency improvements.

  GitHub issue: #5831

• If handle.exe is not available, free disk space monitor will now shell out to PowerShell
  to retrieve the number of open file handles used by the node.

  GitHub issue: #6613

• raft.adaptive_failure_detector.poll_interval exposes aten's poll_interval setting to
  RabbitMQ users. Increasing it can reduce the probability of false positives in clusters where
  inter-node communication links are used at close to maximum capacity.
  The default is 5000 (5 seconds).

  GitHub issue: #6632

• When both disk_free_limit.relative and disk_free_limit.absolute,
  or both vm_memory_high_watermark.relative and vm_memory_high_watermark.absolute are set,
  the absolute settings will now take precedence.

  Contributed by @SimonUnge (AWS).

  GitHub issue: #4980

• Closing channels will now log a warning if they had any messages pending a confirmation from the server.

  Contributed by @Kiruamvp.

Bug Fixes

• rabbitmq-queues grow and rabbitmq-queues shrink misformatted the errors
  they could encounter.

  Contributed by @gomoripeti (CloudAMQP).

  GitHub issue: #6601

Enhancements

• Implicit help command (when CLI tools were invoked without a command name)
  now respects all global flags (such as --node). For example, previously
  the --node flag in

  rabbitmqctl --node [email protected]

  was ignored but now CLI tools would discover what plugins are enabled
  on node [email protected] and include them into help output.

  GitHub issue: #6598

• New key supported by rabbitmqctl list_queues: effective_policy_definition that returns
  merged definitions of regular and operator policies effective for the queue.

  GitHub issue: #6556

Management Plugin

Enhancements

• It is now possible to omit explicitly specifying queue type when declaring
  a queue (or stream) in the management UI, and rely on the default queue type
  configured for the selected virtual host.

  (of 1 second vs. several seconds previously). This means it should be easier
  to spot Shovels that run into flow control using management UI.

  Contributed by @gomoripeti (CloudAMQP).

  GitHub issue: #6615

Sharding Plugin

Bug Fixes

• Plugin could fail to boot and halt node boot due to incorrect boot step
  metadata.

Enhancements

• Import of definition files with many streams is now more efficient.

  GitHub issue: #6436

• Lower CPU footprint in clusters with many mostly idle streams.

  GitHub issue: #6436

• Streams with max_age retention now attempt to reclaim disk space every hour.
  This is relevant in environments with a lot of mostly inactive streams that
  set max_age.

  GitHub issue: #6436

• 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

• Dead-lettering of a large number of messages to a classic mirrored queues now has lower peak memory footprint.

  GitHub issue: #5312

  it will refuse to start instead of ignoring the file.

  GitHub issue: #2610

• Fixed a type analyzer definition.

  Contributed by @illotum (AWS).

  GitHub issue: #6401

  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.
