 # Some breaking changes introduced
-* Please update boost version to at least 1.87.0.
-* When a subscription fails due to the underlying websocket connection fails to open, the emitted message type is SUBSCRIPTION_FAILURE_DUE_TO_CONNECTION_FAILURE instead of SUBSCRIPTION_FAILURE.
-* Removed the spot market making application and the single order execution application.
+* We made a change on how to "Send request by Websocket API".
