+
+
+### Bug Fixes

+* fix payload encoding for v3 clients ([ed50fc3](https://github.com/socketio/engine.io/commit/ed50fc346b9c58459bf4e6fe5c45e8d34faac8da))
+
+
+### Features

+
+
+### Performance Improvements
+
+* refresh ping timer ([#628](https://github.com/socketio/engine.io/issues/628)) ([37474c7](https://github.com/socketio/engine.io/commit/37474c7e67be7c5f25f9ca2d4ea99f3a256bd2de))

+## [6.0.1](https://github.com/socketio/engine.io/compare/6.0.0...6.0.1) (2021-11-06)
+
+
+### Bug Fixes
+
+* fix payload encoding for v3 clients ([3f42262](https://github.com/socketio/engine.io/commit/3f42262fd27a77a7383cdbb44ede7c6211a9782b))
+
+
+
+# [6.0.0](https://github.com/socketio/engine.io/compare/5.2.0...6.0.0) (2021-10-08)
+
+The codebase was migrated to TypeScript ([c0d6eaa](https://github.com/socketio/engine.io/commit/c0d6eaa1ba1291946dc8425d5f533d5f721862dd))
+
+An ES module wrapper was also added ([401f4b6](https://github.com/socketio/engine.io/commit/401f4b60693fb6702c942692ce42e5bb701d81d7)).
+
+Please note that the communication protocol was not updated, so a v5 client will be able to reach a v6 server (and vice-versa).
+
+Reference: https://github.com/socketio/engine.io-protocol
+
+### BREAKING CHANGES
+
+- the default export was removed, so the following code won't work anymore:
+
+```js
+const eioServer = require("engine.io")(httpServer);
+```
+
+Please use this instead:
+
+```js
+const { Server } = require("engine.io");
+const eioServer = new Server(httpServer);
+```
