 # Release notes

+## [4.8.1](https://github.com/socketio/socket.io/compare/socket.io@4.8.0...socket.io@4.8.1) (2024-10-25)
+
+Due to a change in the bundler configuration, the production bundle (`socket.io.min.js`) did not support sending and receiving binary data in version `4.8.0`. This is now fixed.

Ben McCann	7fcddcb3bb	fix(engine.io-client): correctly consume the `ws` package (#5220 ) This should fix the following issue: ``` SyntaxError: Named export 'WebSocket' not found. The requested module 'ws' is a CommonJS module, which may not support all module.exports as named exports. CommonJS modules can always be imported via the default export, for example using: import pkg from 'ws'; const { WebSocket } = pkg; ```	2025-01-07 10:53:32 +01:00
Damien Arrachequesne	7427109658	refactor(eio): bump cookie to version 1.0.2 Release notes: https://github.com/jshttp/cookie/releases/tag/v1.0.0 The types are now included in the npm package. The `CookieSerializeOptions` type, which is used in our `ServerOptions` type, has been renamed to `SerializeOptions`, but there are no breaking change.

Damien Arrachequesne	ca9e994815	fix(sio-client): do not mangle the "_placeholder" attribute The "_placeholder" attribute is used when sending binary data, and was incorrectly mangled (converted to a random short property, like "it", to reduce the bundle size). This bug was introduced in [1], included in `socket.io-client@4.8.0`. [1]: `7085f0e3e4` Related: https://github.com/socketio/socket.io/issues/5215	2024-10-22 11:41:08 +02:00

Damien Arrachequesne	175a2c58c1	fix(eio-client/types): remove ws type from .d.ts file Before this change, the following error would be thrown when compiling with TypeScript: ``` node_modules/engine.io-client/build/esm/transports/websocket.node.d.ts:12:101 - error TS1340: Module 'ws' does not refer to a type, but is used as a type here. Did you mean 'typeof import('ws')'? 12 createSocket(uri: string, protocols: string \| string[] \| undefined, opts: Record<string, any>): import("ws"); ~~~~~~~~~~~~ ``` This behavior was introduced in [1], included in version `6.6.0`. The return type is forced as `any`, so that the `@types/ws` dependency is optional. [1]: `f4d898ee96` Related: https://github.com/socketio/socket.io/issues/5202	2024-10-19 07:09:19 +02:00
