July 2026: Reliability and stability focus in koyeb/control-panel. Resolved a critical organization-switching issue caused by stale project IDs, leading to 401 errors. Implemented proactive currentProjectId cache invalidation before fetching new organization data and hardened validation to gracefully handle 401s from stale projects. This work reduces user-facing switch failures, lowers support load, and improves data consistency during organization transitions. No new features released this month; the emphasis was on reliability, resilience, and business value. Technologies demonstrated include client-side cache invalidation patterns, robust API error handling, and traceability via commit 11a77b21fd6b7bd71bb5940176c6f609621ba4c7.
