Socket.IO 1.3.3 is a backwards-compatible recommended upgrade for everyone.
It addresses a bug in the parser that could break the decoder with maliciously-crafted binary packets.
We now warn about errors in the console if you dont manually specify an
errorevent handler forSocketobjects on the server.
As usual, you can grab the latest client from the CDN!
