  * Domain Migration Update (July 2025):
  * Updated all Viessmann API endpoints from viessmann.com to viessmann-climatesolutions.com
  * as per official Viessmann notification for modernization of their services.
+ *
+ * API v2 Migration Update (December 2025):
+ * Updated /iot/v1/equipment/installations endpoint to /iot/v2/equipment/installations
+ * The v1 endpoint was deprecated and removed on 2025-12-15 (HTTP 410 Gone)
+ *
+ * Feature Name Changes (April 2025):
+ * The adapter dynamically processes all features from the API without hardcoded feature names.
+ * Therefore, all feature naming changes (e.g., hotWaterStorage -> dhwCylinder, heating.buffer -> heating.bufferCylinder,
+ * heating.fuelcell -> fuelCell, heating.scop -> heating.spf, ventilation.operating.programs -> ventilation.quickmodes/levels)
+ * are automatically reflected as the API returns the updated feature names.
