+## [2.3.1](https://github.com/socketio/socket.io-client/compare/2.3.0...2.3.1) (2020-09-30)
+
+The `debug` dependency has been reverted to `~3.1.0`, as the newer versions contains ES6 syntax which breaks in IE
+browsers.
+
+Please note that this only applied to users that bundle the Socket.IO client in their application, with webpack for
+example, as the "official" bundles (in the dist/ folder) were already transpiled with babel.
+
+For webpack users, you can also take a look at the [webpack-remove-debug](https://github.com/johngodley/webpack-remove-debug)
+plugin.
+
+### Bug Fixes
+
+* fix reconnection after opening socket asynchronously ([#1253](https://github.com/socketio/socket.io-client/issues/1253)) ([050108b](https://github.com/Automattic/socket.io-client/commit/050108b2281effda086b197cf174ee2e8e1aad79))

+
+In order to see all the client debug output, run the following command on the browser console – including the desired scope – and reload your app page:
+
+```
+localStorage.debug = '*';
+```
+
+And then, filter by the scopes you're interested in. See also: https://socket.io/docs/logging-and-debugging/
