May 2026 performance summary across mib1185/homeassistant-core and cdce8p/ha-core. Delivered features include improved NoboHub error feedback with explicit IP-vs-serial distinction, DHCP-based auto-discovery for Nobø Ecohub, and enhanced Nobo temperature display precision. Internal stability improvements reduce shared-state risks (HVAC validation removal and mutable defaults in NoboProfileSelector). Quality and maintainability were advanced via Bronze readiness for nobo_hub, test refactors, and a library upgrade to pynobo 1.9.0, along with DHCP rediscovery support and reinforced config-flow error handling.

Month: 2025-10 summary for home-assistant/core focusing on reliability and performance improvements in the DSM integration. Delivered a robust Synology DSM API Initialization Guard by refactoring the DSM configuration flow to create the API object only if it does not already exist. This reduces reinitialization, improves efficiency during reauthentication, and minimizes issues in subsequent setup steps. Minor error handling adjustments and updated test mocks accompany the change to ensure realistic behavior and testing reliability.
