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

Prometheus Plugin

Enhancements

• More data is exposed via the GET /metrics/detailed endpoint.

  GitHub issue: #3520

Management Plugin

Bug Fixes

• When setting topic permissions, the list of exchanges in the UI now honors the
  currently selected virtual host.
