+#### Deprecated DHT commands removed from `/api/v0/dht`
+
+All the DHT commands that were deprecated were finally removed from `/api/v0/dht`. You can now use them via `/api/v0/routing`.
+
+To match this change, the DHT commands in the Go RPC client have been marked as deprecated, and aliased to the Routing interface. All methods previously available under the DHT interface are now available under the Routing interface.
+
+In the next version, all DHT deprecated methods will be removed from the Go RPC client.
