Version compatibility
The Socket.IO protocol has been through a number of revisions, and some of these introduced backward incompatible changes, which means that the client and the server must use compatible versions for everything to work.
The version compatibility chart below maps versions of this package to versions of the JavaScript reference implementation and the versions of the Socket.IO and Engine.IO protocols.
| JavaScript Socket.IO version | Socket.IO protocol revision | Engine.IO protocol revision | Flask-SocketIO version | python-socketio version | python-engineio version |
|---|---|---|---|---|---|
| 0.9.x | 1, 2 | 1, 2 | Not supported | Not supported | Not supported |
| 1.x and 2.x | 3, 4 | 3 | 4.x | 4.x | 3.x |
| 3.x and 4.x | 5 | 4 | 5.x | 5.x | 4.x |
