+## 3.43.0
+**`(fix):`** Fix WebSocket client compilation error when a server message type
+produces the same method name as a lifecycle handler. For example,
+a message type `error` generated `onError(Consumer<Error>)` which
+clashed with the lifecycle `onError(Consumer<Exception>)` due to
+Java generics type erasure. Colliding message handler methods are
+now suffixed with `Message` (e.g. `onErrorMessage`).
