3.0.0-rc1

Features

• add ES6 module export (cbabb03)
• do not reuse the Engine.IO id (bbe94ad)
• remove the implicit connection to the default namespace (249e0be)
• split the events of the Manager and Socket (132f8ec)
• throw upon reserved event names (6494f61)

BREAKING CHANGES

• the Socket instance will no longer forward the events of its Manager

Those events can still be accessed on the Manager instance though:

socket.io.on("reconnect", () => {
  // ...
});

• the slim build was removed

There is now two builds:

• a development build, with the debug dependency: dist/socket.io.js
• a production build, without the debug dependency: dist/socket.io.min.js
