January 2026 monthly summary for apache/shenyu: Implemented Gateway Upstream Health State Preservation During Configuration Updates, preserving unhealthy upstreams during admin-driven config changes to improve resilience and recovery. Refactored UpstreamCacheManager to keep health state across updates, introduced processing for offline and valid upstreams, and exposed map management via UpstreamCheckTask to ensure state consistency. Added comprehensive tests and a targeted performance optimization to skip unnecessary processing when upstream lists are empty. These changes reduce downtime, improve reliability during dynamic reconfiguration, and demonstrate strong maintainability and test coverage.

July 2025 focused on delivering Swagger/OpenAPI import capabilities into ShenYu Admin for the apache/shenyu repo, with emphasis on safe import, code quality, and enhanced API management. Key outcomes include a new import feature for Swagger 2.0 and OpenAPI 3.0 definitions, robust URL validation to mitigate SSRF risks, and a code refactor aimed at maintainability and efficiency to support seamless integration of external API definitions. No major bugs closed this month; the change lays groundwork for faster, safer external API onboarding and improved API lifecycle management.
