|
| 73 |
|
| 74 | ### BREAKING CHANGES
|
| 75 |
|
| 76 | * the Socket instance will now emit a "connect_error" event instead of "error" (which is not a reserved event anymore)
|
| 77 |
|
| 78 | ```js
|
| 79 | // before
|
| 80 | socket.on("error", () => {});
|
| 81 |
|
| 82 | // after
|
| 83 | socket.on("connect_error", () => {});
|
| 84 | ```
|
| 85 |
|
| 86 | * the Socket#binary() method is removed, as this use case is now covered by the ability to provide your own parser.
|
| 87 |
|
| 88 | * the Socket instance will no longer forward the events of its Manager
|
| 89 |
|
| 90 | Those events can still be accessed on the Manager instance though:
|
| 91 |
|
| 92 | ```js
|
| 93 | socket.io.on("reconnect", () => {
|
| 94 | // ...
|
| 95 | });

|
| 164 | * the Socket instance will no longer forward the events of its Manager
|
| 165 |
|
| 166 | Those events can still be accessed on the Manager instance though:

|
| 175 | ## [2.3.1](https://github.com/socketio/socket.io-client/compare/2.3.0...2.3.1) (2020-09-30)
|
| 176 |
|
| 177 | The `debug` dependency has been reverted to `~3.1.0`, as the newer versions contains ES6 syntax which breaks in IE
|
| 178 | browsers.
|
| 179 |
|
| 180 | Please note that this only applied to users that bundle the Socket.IO client in their application, with webpack for
|
| 181 | example, as the "official" bundles (in the dist/ folder) were already transpiled with babel.
|
| 182 |
|
| 183 | For webpack users, you can also take a look at the [webpack-remove-debug](https://github.com/johngodley/webpack-remove-debug)
|
| 184 | plugin.
