October 2025: Delivered Zephyr Agent Server Token Authentication for Zephyr-packages, enabling server-to-server authentication via environment-stored tokens. The flow now prioritizes secret tokens, then server tokens, and finally existing tokens, improving security and deployment flexibility. Commit: 99f60adc21ee49f08e3495f807c6ec9a754f631f (feat: server token (#229)).

September 2025: Delivered a major revamp of the authentication layer for Zephyr-packages by migrating from a WebSocket-based flow to a Server-Sent Events (SSE) based mechanism. Implemented a dedicated AuthListener and an authentication worker, and updated API gateway configurations to improve reliability, clarity, and scalability of the authentication flow. This reduces coupling to WebSocket, enhances fault tolerance, and sets the stage for further security and observability improvements across the repository.

May 2025 monthly summary for Zephyr-packages (ZephyrCloudIO/zephyr-packages). Delivered two targeted features focused on the preview workflow and build tooling, along with code organization improvements. No separate major bugs fixed were documented this month; however, a build-specific fix for the preview environment was included as part of the feature work. Impact includes more reliable preview URL handling, a smoother preview experience for customers, and a faster, more stable build process through tooling updates.

Dec 1, 2024

December 2024 monthly summary for ZephyrCloudIO/zephyr-documentation focusing on the ZephyrDependencies documentation update. Delivered targeted developer-facing guidance for managing micro-frontend dependencies, including version specification in package.json, with practical examples and clarified default behavior to prevent remote application version conflicts. The work aligns with improving developer experience and reducing support friction by providing clear, actionable docs.
