2 Commits • 1 Features
Oct 1, 2025October 2025: Delivered key firmware delta orchestration enhancements and fixed a user registration validation bug in nerves_hub_web. The team implemented a dedicated preparation step for delta updates, reworked delta handling, added readiness checks, delta URL generation, and deployment group status management during delta preparation, with improved error handling and logging for delta generation failures. Also fixed overly restrictive name validation by relaxing disallowed character checks, increasing onboarding success for diverse user names. These changes reduce firmware deployment risk, improve update reliability, and smooth the user onboarding experience, demonstrating strong refactoring, instrumentation, and cross-component collaboration.

Jul 1, 2025July 2025 monthly summary for nerves_hub/nerves_hub_web focused on delivering business value through user experience improvements and robust firmware update capabilities. Key outcomes include UI enhancements with a logout button and user menu across both layouts, comprehensive tests for logout functionality, and substantial reliability improvements to the delta update flow, including version checks, FAT support, encryption, and metadata handling. The update logic and firmware lookup/delta generation were refactored to gracefully handle missing source firmware, reducing false error reporting and noise in monitoring. Sentry reporting was adjusted to avoid noise on harmless missing sources. Overall, these changes improve user session security, OTA update resilience, and maintainability through centralized version requirements in the Confuse library.
