In August 2025, EMQX core delivered reliability improvements and dependency upgrades that reduce runtime risk and improve tooling compatibility. Key outcomes include a Unicode-aware congestion handling fix preventing crashes with Unicode usernames, and upgrades to observer_cli (1.8.4) and ekka (0.23.1) for better stability and features. Business impact: lower incident rate, smoother deployments, and improved developer experience. Technical accomplishments include proper Unicode handling via unicode:characters_to_binary, dependency management in mix.exs and rebar.config, and alignment with current ecosystem versions.

March 2025 monthly summary for emqx/emqx: delivered features to improve observability and reliability, fixed a critical subscription bug, and enhanced documentation and metrics. Focused on business value and maintainability with concrete delivered items and tests.

February 2025: Key work centered on strengthening security, stability, and maintenance through targeted dependency upgrades across emqx/emqx and rabbitmq/rabbitmq-server. No customer-facing bug fixes this month; instead, upgrades reduce risk and improve compatibility with downstream tooling. The work established a foundation for future features by aligning tooling versions and build configurations across repos.

January 2025 monthly summary focusing on key achievements in the EMQX project. Delivered two critical fixes with clear business value: improved dashboard metric accuracy and strengthened FIFO handling under full queue conditions. Updated documentation and changelogs to reflect the changes, enhancing maintainability and operator clarity.

December 2024 focused on documentation accuracy, CLI reliability, and deployment troubleshooting to reduce user error and support overhead. Delivered three concrete items across two EMQX repositories: corrected URL templating syntax in EMQX docs to improve HTTP bridge configuration clarity; fixed CLI output to JSON for an empty plugins list to ensure consistent UX; and added a Docker Compose health check troubleshooting FAQ in EMQX Docs to guide users through common unhealthy states. These changes enhance configuration clarity, CLI predictability, and onboarding for Docker deployments, reducing support time and increasing user satisfaction.

November 2024 in EMQX (repo: emqx/emqx) focused on stability, configuration reliability, and observability. Delivered four primary changes: WebSocket stability fixes, Auto_Subscribe configuration/import fixes, Crash dump timestamping for data preservation, and Monitoring data clear API with docs. These changes reduce runtime crashes, improve reliability of auto_subscribe, prevent loss of crash data, and enable API-driven monitoring data management, delivering measurable business value in uptime, configuration correctness, and operational clarity.

For 2024-10, the EMQX development cycle focused on stability and reliability of the Retainer API within emqx/emqx. Key outcomes include a robust fix to prevent crashes when the retainer is disabled, and ongoing improvements to the API through safer backend module interactions and default-value fallbacks. A changelog entry was added to reflect release 14090. This work reduces runtime incidents, improves uptime, and streamlines future maintenance of the Retainer API, delivering measurable business value for reliability and user trust.
