Changes from version 1 to 2

These are the changes in the API since version 1.1.1:

• It now supports different WebSocket protocol versions simultaneously. Now the listener requires that at least one standard is registered before start:

var rfc6455 = new vtortola.WebSockets.Rfc6455.WebSocketFactoryRfc6455(server);
server.Standards.RegisterImplementation(rfc6455);
server.Start();

• Message extensions are now appended to the WebSocket implementations, rather than in the listener itself, so it is possible to enable different extensions for each WebSocket implementation.

var rfc6455 = new vtortola.WebSockets.Rfc6455.WebSocketFactoryRfc6455(server);
rfc6455.MessageExtensions.RegisterExtension(new WebSocketDeflateExtension());
server.Standards.RegisterImplementation(rfc6455);

• It is possible to flush asynchronously and still be able of pushing more data. This is handy for doing streaming, since buffering is by default.

• It is possible to close asynchronously. This is the best way of ending a message.

using (var messageWriter = ws.CreateMessageWriter(WebSocketMessageType.Text))
{
    await messageReader.CopyToAsync(messageWriter).ConfigureAwait(false);
    await messageWriter.CloseAsync(cancellation).ConfigureAwait(false);
}

• It now measures latency. If the WebSocket implementation fulfill the contract IWebSocketLatencyMeasure, it will expose a Latency property that tells the latency of the last ping. WebSocketFactoryRfc6455 implementation fulfills this contract.

• BufferManager: Now in the options, it is possible to pass a BufferManager object, that will be used to instantiate the Byte[] each WebSocket uses.

• More memory efficient. Each WebSocket uses now a single Byte[] array, and no other arrays are created.
