- Added configurable default worker pool size, new health check and observability diagnostics commands, and HTTPS proxy support for the Trust Store plugin.
- Fixed bugs across core server, CLI tools, management, Shovel, Web MQTT/STOMP plugins, and Debian packaging (e.g., exclusive queue restart, CLI report failures, Shovel reconnection, connection limits).
- Breaking changes: dropped support for Erlang/OTP 19.3 and OpenSUSE Leap 42.3; when upgrading to Erlang 21+ the RabbitMQ server must be upgraded first.
