Use the jsonMessageReplacer when automatically responding to a ping with a pong, on both the client and the server

Add an isProd option to the ws, uWebSockets.js and @fastify/websocket use-server helpers, matching the existing crossws option. It controls whether internal error messages are masked with Internal server error before reaching the client, defaulting to the NODE_ENV === 'production' check as before. This lets apps running in production keep reporting onConnect error messages to the client by opting out, or mask eagerly in non-production environments.

Fix the client closing an in-use socket when many subscriptions complete at once and a new one subscribes within the lazyCloseTimeout

Avoid an unhandled rejection when a subscription is disposed before the connection is acknowledged and the socket closes before the subscription releases its connection lock (for example, when the client is disposed while connecting and the WebSocket implementation delivers the close event on a microtask).

Add onPing and onPong server callbacks to ServerOptions, similar to onConnect and onDisconnect. The callbacks receive the connection Context as the first argument and the ping/pong payload as the second, allowing apps to log or react to subprotocol-level pings with access to connection state. The automatic pong reply is preserved when using the server-level onPing callback; the low-level websocket onPing listener still disables the automatic reply for full manual control.

Allow operation IDs that match properties inherited from Object.prototype.

Fix the client leaking memory per operation on long-living connections

Support crossws 0.4 by selecting the GraphQL WebSocket subprotocol during the upgrade handshake. Preserve automatic protocol negotiation in the legacy crossws 0.3 Node and uWebSockets adapters.

Fix the CrossWS adapter ignoring socket closes issued from server.opened

Fix typings for WebSocketServer

Add parse option for custom GraphQL parsing

Disposing of a client event listener twice no longer removes an unrelated listener

Add support for graphql@17
