XChange: Binance "invalid WebSocket Extension handshake"

Hello,

I’m suddenly experiencing issues connecting to Binance streaming API, since 13:20 UTC today. I checked their changelog and there seem to have been some changes today to the API, see https://binance-docs.github.io/apidocs/spot/en/

It can be reproduced with this example

    StreamingExchange exchange = StreamingExchangeFactory.INSTANCE.createExchange(BinanceStreamingExchange.class);

    ProductSubscription streamSubscription = ProductSubscription.create()
    .addOrderbook(CurrencyPair.BTC_EUR)
    .build();

    exchange.connect(streamSubscription).blockingAwait();

    Disposable subscription1 = exchange.getStreamingMarketDataService()
        .getOrderBook(CurrencyPair.BTC_EUR)
        .subscribe(
            book -> System.out.println(book),
            throwable -> System.out.println(throwable));

The error I’m getting is

Exception in thread "main" io.netty.handler.codec.CodecException: invalid WebSocket Extension handshake for "permessage-deflate; server_no_context_takeover; client_max_window_bits=15"

Could anyone help? Was there a Binance API change that introduced some incompatible changes?
