Changes Worth Mentioning

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

Core Server

Enhancements

• A minor quorum queue optimization.

  GitHub issue: #4873

Bug Fixes

• Avoid seeding default user in old clusters that still use the deprecated management.load_definitions option. This could result in an extra user, guest or under an overriden default user name, to appear in addition to the user accounts imported from definitions.

  Note that the default user with well-known name can only connect from localhost by default, so this would not expose reasonably configured production nodes to remote connections.

  GitHub issue: #4904

• Streams could run into an exception or fetch stale stream position data in some scenarios.

  GitHub issue: #4898

• rabbitmqctl set_log_level did not have any effect on logging via amq.rabbitmq.log (the system exchange for logging)

  Contributed by Péter @gomoripeti Gömöri (CloudAMQP).

  GitHub issue: #4891

CLI Tools

Bug Fix

• rabbitmq-diagnostics status is now more resilient and won't fail if free disk space monitoring repeatedly fails (gets disabled) on the node.

  GitHub issue: #4900

Dependency Upgrades

• ra upgraded from 2.0.11 to 2.0.13
