v4.0.2

• Use SocketIOClientOption for SocketEngine

v4.0.1

• Fix engine not being released along with engine

v4.0.0

• Change to a more typesafe options interface.

Instead of using a dictionary, it is now recommended you use a set of SocketIOClientOption.

let socket = SocketIOClient(socketURL: "", opts: ["log": true, "nsp": "/swift"])

Now becomes

let socket = SocketIOClient(socketURL: "", options: [.Log(true), .Nsp("/swift")])

• Fix carthage builds

v3.1.5

• Fixed timeout handler being called after closing the connection
• Fixed crash where pointing to non socket.io server

v3.1.4

• Fixes a bug with error packets not being correctly handled

v3.1.3

• Fixes bug in WebSocket that could cause invalid upgrades.
• Fixes several crash cases relating to closing socket

v3.1.2

• Fixes namespaces

v3.1.1

• Add internal Either type
• Remove tvOS from master

v3.1.0

• This version includes breaking changes, but reconciles the Objective-C and Swift apis. Most notable are changes to how acking is done

socket.on("someEvent") {data, ack in
    ack?(1, 2, 4)
}

Would become

socket.on("someEvent") {data, ack in
    ack?.with(1, 2, 4)
}

• The Objective-C method for adding events has been merged with the Swift method.
• The event callback definition has been changed from (NSArray?, ((AnyObject...) -> Void)?) -> Void To ([AnyObject], SocketAckEmitter?) -> Void
• A method has been added to execute an event only once.
