April 2026 monthly summary for hivemq-edge focused on OpenAPI artifact cleanup following Swagger-to-Redocly migration. This work reduced maintenance surface, eliminated an unused OpenAPI YAML, and aligned tooling with current standards without impacting runtime behavior.

March 2026 (Month: 2026-03) delivered targeted API improvements, reliability enhancements, and build/quality work for hivemq-edge with measurable business value. Highlights include enhanced OpenAPI documentation with dynamic version stamping, token caching to stabilize external calls, and a major build-system modernization to improve efficiency and security. In parallel, test stability was reinforced after SDK changes to reduce flaky tests and accelerate release readiness.

February 2026 summary: Delivered API usability enhancements, reliability improvements, and release automation across HiveMQ Edge and Helm charts. Key actions included maintaining and simplifying the OpenAPI spec, re-enabling and hardening telemetry, boosting MQTT bridge robustness against concurrency and payload size, hardening security and JDBC reliability, and keeping adapters/SDKs current with 2026 releases. Helm Chart releases 2026.2 and 2026.3 were released with automated release PR workflows, improving release cadence and branch management. Overall impact: improved API usability, telemetry data quality, message safety, security reliability, and faster, more predictable releases. Technologies demonstrated include OpenAPI, telemetry instrumentation, MQTT bridge robustness, security file handling, JDBC reliability, and automation of Helm chart releases with CI workflows.

December 2025 performance highlights across hivemq-edge and related tooling. Focused on release readiness, developer experience, reliability improvements, and deployment automation. Delivered version-aligned metadata, expanded API exposure, dynamic connection handling, and deployment chart updates to support smoother packaging, integration, and edge stability.

November 2025 (2025-11): Focused on stability and observability for hivemq-edge bridging. Implemented a locking mechanism to serialize bridge updates to prevent race conditions, complemented by extensive logging for traceability and debugging. This work reduces intermittent failures, improves operational reliability, and lays groundwork for safer concurrent bridge operations.

October 2025: Delivered resilience improvements for the OPC UA Adapter in hivemq-edge by improving deserialization of configuration where Auth and Security sections may be missing or empty. Implemented custom JSON deserializers for Auth and Security, and added unit tests to cover edge cases, ensuring null handling when no structure is defined. These changes reduce configuration-related runtime errors and improve operator confidence in the OPC UA integration.

September 2025 monthly summary focusing on delivering features, fixing key issues, and enabling stronger release governance across HiveMQ Edge and Helm charts.

June 2025 monthly summary focusing on release engineering, API documentation, and security upgrades to prepare for the 2025.9 release cycle across hivemq-edge and related charts. Key outcomes include stabilizing versioning across modules, introducing OpenAPI 3.0 spec for HiveMQ Edge REST API, applying TLS/security fixes through library upgrades, and aligning deployment artifacts with the 2025.9 release.

May 2025 monthly summary for hivemq-edge: Delivered a comprehensive OpenAPI 3.0 schema for the HiveMQ Edge REST API, detailing endpoints for authentication, data hub management (behavior policies, data policies, schemas, scripts, states), frontend interactions, gateway configuration, health checks, bridges, protocol adapters, payload sampling, topic filters, and metrics. Removed the standalone OpenAPI specification file to reduce maintenance and technical debt, and prepared API work for release cycles (2025.8 and 2025.9 SNAPSHOT). The changes established a clear API contract, enabling client code generation and smoother evolution of the API surface.

April 2025 (2025-04) monthly summary for hivemq-edge focused on release maintenance, API documentation simplification, and build/config hygiene to accelerate next development cycle. The work prioritized release continuity, reduced maintenance overhead, and preserved downstream development momentum.

March 2025 – hivemq-edge: Focused on resilience, API consistency, and maintainability to boost data reliability and downstream integration quality.

November 2024 (2024-11) — Focused on dependency hygiene in hivemq-community-edition. No bugs fixed this month; main activity was updating dependencies to newer Guava and Jackson patches in the version catalog, enhancing security and performance while keeping the codebase unchanged. Key deliverables: - Dependency Version Updates (Guava and Jackson): Updated minor versions in the version catalog for hivemq-community-edition (commit 91671f9df573b708ceee6740337233108a12e19b). - Changes confined to the version catalog with no code changes, minimizing risk. - Improved security posture and potential performance improvements through library patches. - Documented the change for audit trail. Impact: - Reduced security risk and ensured compatibility with latest libraries. - Maintained production readiness with minimal risk; no code changes, reducing regression surface. Technologies/skills demonstrated: - Dependency management and version catalogs (Gradle/Build tooling) - Repository hygiene and release engineering - Security awareness through timely updates
