##### Important note :warning: from Engine.IO [3.2.0 release](https://togithub.com/socketio/engine.io/releases/tag/3.2.0)
There are two non-breaking changes that are somehow quite important:
- `ws` was reverted as the default wsEngine ([https://github.com/socketio/engine.io/pull/550](https://togithub.com/socketio/engine.io/pull/550)), as there was several blocking issues with `uws`. You can still use `uws` by running `npm install uws --save` in your project and using the `wsEngine` option:
```js
var engine = require('engine.io');
var server = engine.listen(3000, {
wsEngine: 'uws'
});
```
- `pingTimeout` now defaults to 5 seconds (instead of 60 seconds): [https://github.com/socketio/engine.io/pull/551](https://togithub.com/socketio/engine.io/pull/551)

[Compare Source](https://togithub.com/socketio/socket.io/compare/1.7.4...2.0.0)
This major release brings several performance improvements:
- [uws](https://togithub.com/uWebSockets/uWebSockets) is now the default Websocket engine. It should bring significant improvement in performance (particularly in terms of memory consumption) (https://github.com/socketio/engine.io/releases/tag/2.0.0)
- the Engine.IO and Socket.IO handshake packets were merged, reducing the number of roundtrips necessary to establish a connection. ([#2833](https://togithub.com/socketio/socket.io/issues/2833))
- it is now possible to provide a custom parser according to the needs of your application ([#2829](https://togithub.com/socketio/socket.io/issues/2829)). Please take a look at the [example](https://togithub.com/socketio/socket.io/tree/master/examples/custom-parsers) for more information.
Please note that this release is not backward-compatible, due to:
- a breaking change related to utf-8 encoding in engine.io-parser ([https://github.com/socketio/engine.io-parser/pull/81](https://togithub.com/socketio/engine.io-parser/pull/81))
- an update to make the socket id on the client match the id on the server-side ([https://github.com/socketio/socket.io-client/pull/1058](https://togithub.com/socketio/socket.io-client/pull/1058))
Please also note that if you are using a self-signed certificate, `rejectUnauthorized` now defaults to `true` ([https://github.com/socketio/engine.io-client/pull/558](https://togithub.com/socketio/engine.io-client/pull/558)).
Finally, the API documentation is now in the repository ([here](https://togithub.com/socketio/socket.io/blob/master/docs/API.md)), and the content of the website [here](https://togithub.com/socketio/socket.io-website). Do not hesitate if you see something wrong or missing!

You can still use `uws` by running `npm install uws --save` in your project and using the `wsEngine` option: ```js var engine = require('engine.io'); var server = engine.listen(3000, { wsEngine: 'uws' }); ``` - `pingTimeout` now defaults to 5 seconds (instead of 60 seconds): [https://github.com/socketio/engine.io/pull/551](https://togithub.com/socketio/engine.io/pull/551) ### [`v2.0.4`](https://togithub.com/socketio/socket.io/releases/tag/2.0.4) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.3...2.0.4) #### Bug fixes - do not throw when receiving an unhandled error packet ([#3038](https://togithub.com/socketio/socket.io/issues/3038)) - reset rooms object before broadcasting from namespace ([#3039](https://togithub.com/socketio/socket.io/issues/3039)) ##### Links: - Milestone: [2.0.4](https://togithub.com/socketio/socket.io/milestone/13) - Diff: [2.0.3...2.0.4](https://togithub.com/socketio/socket.io/compare/2.0.3...2.0.4) - Client release: [2.0.4](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.4) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.3`](https://togithub.com/socketio/socket.io/releases/tag/2.0.3) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.2...2.0.3) #### Bug fixes - reset rooms object before broadcasting ([#2970](https://togithub.com/socketio/socket.io/issues/2970)) - fix middleware initialization ([#2969](https://togithub.com/socketio/socket.io/issues/2969)) ##### Links: - Milestone: [2.0.3](https://togithub.com/socketio/socket.io/milestone/12) - Diff: [2.0.2...2.0.3](https://togithub.com/socketio/socket.io/compare/2.0.2...2.0.3) - Client release: [2.0.3](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.3) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.2`](https://togithub.com/socketio/socket.io/releases/tag/2.0.2) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.1...2.0.2) #### Bug fixes - fix timing issues with middleware ([#2948](https://togithub.com/socketio/socket.io/issues/2948)) ##### Links: - Milestone: [2.0.2](https://togithub.com/socketio/socket.io/milestone/11) - Diff: [2.0.1...2.0.2](https://togithub.com/socketio/socket.io/compare/2.0.1...2.0.2) - Client release: [2.0.2](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.2) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.1`](https://togithub.com/socketio/socket.io/releases/tag/2.0.1) [Compare Source](https://togithub.com/socketio/socket.io/compare/2.0.0...2.0.1) #### Bug fixes \- update path of client file ([#2934](https://togithub.com/socketio/socket.io/issues/2934)) ##### Links: - Milestone: [2.0.1](https://togithub.com/socketio/socket.io/milestone/9) - Diff: [2.0.0...2.0.1](https://togithub.com/socketio/socket.io/compare/2.0.0...2.0.1) - Client release: [2.0.1](https://togithub.com/socketio/socket.io-client/releases/tag/2.0.1) - Diff `engine.io`: - - Diff `ws`: - ### [`v2.0.0`](https://togithub.com/socketio/socket.io/releases/tag/2.0.0) [Compare Source](https://togithub.com/socketio/socket.io/compare/1.7.4...2.0.0) This major release brings several performance improvements: - [uws](https://togithub.com/uWebSockets/uWebSockets) is now the default Websocket engine. It should bring significant improvement in performance (particularly in terms of memory consumption) (https://github.com/socketio/engine.io/releases/tag/2.0.0) - the Engine.IO and Socket.IO handshake packets were merged, reducing the number of roundtrips necessary to establish a connection. ([#2833](https://togithub.com/socketio/socket.io/issues/2833)) - it is now possible to provide a custom parser according to the needs of your application ([#2829](https://togithub.com/socketio/socket.io/issues/2829)). Please take a look at the [example](https://togithub.com/socketio/socket.io/tree/master/examples/custom-parsers) for more information. Please note that this release is not backward-compatible, due to: - a breaking change related to utf-8 encoding in engine.io-parser ([https://github.com/socketio/engine.io-parser/pull/81](https://togithub.com/socketio/engine.io-parser/pull/81)) - an update to make the socket id on the client match the id on the server-side ([https://github.com/socketio/socket.io-client/pull/1058](https://togithub.com/socketio/socket.io-client/pull/1058)) Please also note that if you are using a self-signed certificate, `rejectUnauthorized` now defaults to `true` ([https://github.com/socketio/engine.io-client/pull/558](https://togithub.com/socketio/engine.io-client/pull/558)). Finally, the API documentation is now in the repository ([here](https://togithub.com/socketio/socket.io/blob/master/docs/API.md)), and the content of the website [here](https://togithub.com/socketio/socket.io-website).
