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.

If you are using the Python client and server, the easiest way to ensure compatibility is to use the same version of this package for the client and the server. If you are using this package with a different client or server, then you must ensure the versions are compatible.

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 | python-socketio version -|-|-|- 0.9.x | 1, 2 | 1, 2 | Not supported 1.x and 2.x | 3, 4 | 3 | 4.x 3.x and 4.x | 5 | 4 | 5.x
