 # Changelog
 
+## 0.15.7
+
+- Fixes mixed V1/V2 Local discovery: legacy/plain discovery envelopes are no longer treated as proof that a unit is V1.
+- Uses the inner GREE `ver` metadata as a discovery protocol hint (`V1.*` -> V1, `V2.*`/newer -> V2), while keeping unknown results in Auto mode.
+- Auto discovery now verifies the protocol during bind with V1/V2 fallback and persists the generation that actually succeeds; explicit V1/V2 discovery remains locked to the selected protocol.
+- The discovery review UI shows Auto for unresolved candidates instead of incorrectly labeling them V1.
+
 ## 0.15.6
 
 - Removes the obsolete add-all `POST /api/discovery` endpoint and its compatibility-only merge path.
