 # Changelog
 
+## 0.1.13
+
+- Marked BLE service-discovery disconnect errors as retryable (`failed to discover services, device disconnected`), so the add-on retries automatically.
+
 ## 0.1.12
 
 - Improved BLE connection target resolution by preferring discovered BLE device objects over raw MAC strings to avoid BlueZ `br-connection-not-supported` on some hosts.
