- Requires Erlang 24.3 or later; older Erlang versions are unsupported and nodes will fail to start.
- Core server improvements: reduced memory footprint for dead‑lettering to classic mirrored queues and more detailed heartbeat timeout logs.
- Bug fixes across components (rabbitmqctl tag handling, stream plugin empty‑body translation, Web‑STOMP error‑frame delivery) and dependency upgrades (ra 2.4.6, prometheus.erl 4.10.0).
