Core Server

Enhancements

  • Quorum queues: better forward compatibility with (currently in preview) RabbitMQ 3.10.

GitHub issue: #4560

  • Significantly faster queue re-import from definitions
    on subsequent node restarts. Initial definition import still takes
    the same amount of time as before.

GitHub issue: #4538

  • Significantly faster exchange re-import from definitions
    on subsequent node restarts. Initial definition import still takes
    the same amount of time as before.

GitHub issue: #4585

  • RabbitMQ nodes will now filter out certain log messages related to
    connections, channels, and queue leader replicas receiving internal protocol messages
    sent to this node before a restart. These messages usually raise more questions
    and cause confusion than help.

It is still possible to detect relevant underlying events (node or connection failures)
from other log messages.

GitHub issue: #4557

Bug Fixes

  • rabbitmq-upgrade await_online_synchronized_mirror is now a no-op in single node
    clusters

GitHub issue: #4570

Prometheus Plugin

Bug Fixes

  • One metric that was exposed via CLI tools and management plugin's HTTP API
    was not exposed via Prometheus scraping API.
