+# Release Notes
+
+## Bug fixes
+
+* The REST proxy (`grpc-gateway` library) had a fallback that redirected `POST`
+  requests to another endpoint _with the same URI_ if no endpoint for `POST` was
+  registered. [This default behavior was turned
+  off](https://github.com/lightningnetwork/lnd/pull/6359), enabling strict
+  HTTP method matching.
