- Fixed numerous crashes and errors across core server, stream, management, federation, Prometheus, shovel, and STOMP plugins (e.g., recovery crashes, message rejection, heartbeat monitor crashes)
- Improved performance and configurability: faster Mnesia‑to‑Khepri migration, added aten settings in rabbitmq.conf, reduced log noise from probes, clearer plugin error messages, and extra policy fields in management API responses
- Enhanced validation and request handling: early rejection of oversize request bodies, stricter API validation, and better handling of load‑balancer probes
