| 57 | Encoding changes between v3 and v4:
|
|---|
| 58 |
|
|---|
| 59 | - encodePacket with string
|

|---|
| 61 | - output in v3: `"4hello"`
|
|---|
| 62 | - output in v4: `"4hello"`
|
|---|
| 63 |
|
|---|
| 64 | - encodePacket with binary
|
|---|
| 65 | - input: `{ type: 'message', data: <Buffer 01 02 03> }`
|
|---|
| 66 | - output in v3: `<Buffer 04 01 02 03>`
