30This major release contains the necessary changes for the version 4 of the Engine.IO protocol. More information about the new version can be found [there](https://github.com/socketio/engine.io-protocol#difference-between-v3-and-v4).
31
32Encoding changes between v3 and v4:
33
34- encodePacket with string
35 - input: `{ type: "message", data: "hello" }`
36 - output in v3: `"4hello"`
37 - output in v4: `"4hello"`
38
39- encodePacket with binary
40 - input: `{ type: 'message', data: <Buffer 01 02 03> }`
41 - output in v3: `<Buffer 04 01 02 03>`
42 - output in v4: `<Buffer 01 02 03>`
43
44- encodePayload with strings
45 - input: `[ { type: 'message', data: 'hello' }, { type: 'message', data: '€€€' } ]`
46 - output in v3: `"6:4hello4:4€€€"`
47 - output in v4: `"4hello\x1e4€€€"`
48
49- encodePayload with string and binary
50 - input: `[ { type: 'message', data: 'hello' }, { type: 'message', data: <Buffer 01 02 03> } ]`
51 - output in v3: `<Buffer 00 06 ff 34 68 65 6c 6c 6f 01 04 ff 04 01 02 03>`
52 - output in v4: `"4hello\x1ebAQID"`
53
54Please note that the parser is now dependency-free! This should help reduce the size of the browser bundle.
