Month: 2024-11 Overview: Delivered user-facing clarity for AMQP 1.0 vs AMQP 0.9.1 behavior in the website UI and RPC guidance, improved internal documentation for Event Exchange Plugin, and documented MQTT re-authentication and QoS 2 handling. Strengthened test stability and centralized type inference logic to reduce duplication and risk. These changes improve customer onboarding, reduce support friction, and lower maintenance risk across website and server components. Key initiatives and outcomes: - Features delivered across rabbitmq/rabbitmq-website: • AMQP 1.0 visibility in Management UI and RPC guidance: clarify management UI behavior (show message rates for AMQP 0.9.1 only), provide RPC guidance for AMQP 1.0 clients, and note Direct Reply-to remains exclusive to AMQP 0.9.1. Commits: 96c8ffa5ad83e07a423e8953081695cf294f6ac8; 1216c94e0e6c509e04b8c33835c183775aad18c5. • Event Exchange Plugin documentation improvements: consolidate event type docs and clarify consumption of internal events. Commit: ff0dc93f1044b8530a0524333c914186f8457252. • MQTT re-authentication and QoS 2 handling documentation: document limitations on MQTT 5.0 AUTH packets and explain QoS 2 handling when tokens expire. Commit: 0da41f3b986a2a19f29b4ede25707d06a5ff1eca. - Features/Bugs addressed in rabbitmq/rabbitmq-server: • Bug: MQTT management plugin connection test reliability fix by replacing direct assertions with an eventually macro to wait for the expected state, increasing test stability. Commit: 090384fe376d9316eba503987c492d20b74bf51f. • Bug: AMQP 1.0 Erlang client type inference centralization to amqp10_client_types:infer/1 to reduce duplication and prevent potential integer overflows, improving maintainability and reliability. Commit: 6e8b566323a6777fdcfdbc6fa486c35394ff99d5.
