Core Server

Bug Fixes

• When a TLS-enabled listener failed to stop, it logged all of its settings
  which could contain sensitive values.

  GitHub issue: #3803

Enhancements

• Quorum queues now store commands for enqueued messages in a more compact format
  on disk (some derivative data has been dropped).

  GitHub issue: #3804

• queue.declare-ok response to AMQP 0-9-1 clients operating on a stream could return a ready-for-delivery
  message count value that was out of sync with the stream leader replica.

  GitHub issue: #3814

• Classic queues now deliver more efficiently on channels that had global QoS changed
  during consumer operation.

  GitHub issue: #3805

Management Plugin

Bug Fixes

• A help tip on the policies page was misplaced.

  Contributed by @johanrhodin

  GitHub issue: #3825

Management Agent Plugin

Core Server

Bug Fixes

• When the mandatory flag was used when publishing to classic queues,
  but publisher confirms were not, channels memory usage would grow indefinitely.

  GitHub issue: #3560

• rabbitmq-diagnostics memory_breakdown failed to read memory of connection
  reader, writer and channel processes.

  GitHub issue: #3570

• In some environments, Stream replicas advertised IP addresses that could not be reached by cluster peers
  (eg. IP addresses behind a NAT in a Docker deployment). RabbitMQ node hostnames are now advertised as well
  so that other peers can resolve them to get an externally visible IP address.

  GitHub issue: rabbitmq/osiris#53

All Components

• All bytecode is now compiled using the +deterministic compiler flag. This should eliminate the capture of some irrelevant build environment attributes in produced artifacts, improve consistency between builds, and reduce the file level diff between release artifacts.

  GitHub issue: #3442

Core Server

Enhancements

• Classic queue shutdown now uses a much higher timeout (up to 10 minutes instead of 30 seconds).

  In environments with many queues (especially mirrored queues) and many consumers this means that
  the chance of queue indices rebuilding after node restart is now substantially lower.

  GitHub issue: #3409

Bug Fixes

• Quorum queues no longer leak memory and disk space when a consumer is repeatedly added and cancelled on an empty queue.

  GitHub issue: #3445

Prometheus Plugin

Enhancements

• More configurability for metrics exposed via the Prometheus endpoint.

  GitHub issue: #3421

Shovel Plugin

Bug Fixes

• Shovel URIs could be logged with credentials in some scenarios.
