TCPClient Device OS release/stable Argon

I compiled and uploaded the Device OS to the device https://github.com/particle-iot/device-os/tree/release/stable using the command
make clean all PLATFORM=argon -s program-dfu
branch = release/stable
And now my user code is not working.
I get message

all works!!
after  setCredentials!!
after connect!!
ip resolve!!
try connecting...
connected
hello.

but I don’t get html code like before
If I return an old firmware everything works fine.

#include "Particle.h"
TCPClient client;
byte mac[6];
SerialLogHandler logHandler;

void setup()
{
    WiFi.on();
    Serial.begin(9600);
    waitFor(Serial.isConnected, 30000);
    WiFi.macAddress(mac);
    Serial.printlnf("mac: %02x:%02x:%02x:%02x:%02x:%02x", mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);
    WiFi.setCredentials("****", "*********");
    Serial.println("after  setCredentials!!");
    WiFi.connect();
    Serial.println("after  connect!!");
    IPAddress ip;
    ip = WiFi.resolve("www.google.com");
    if(ip) {
        Serial.println("ip  resolve!!");
    } else {
        Serial.println("ip  resolution failed!!");
    }

    Serial.println("try connecting...");
    if (client.connect(ip, 80))
    {
        Serial.println("connected");
        client.println("GET /search?q=unicorn HTTP/1.0");
        client.println("Host: www.google.com");
        client.println("Content-Length: 0");
        client.println();
    }
    else
    {
        Serial.println("connection failed");
    }
}

void loop()
{
    if (client.available())
    {
        char c = client.read();
        Serial.print(c);
    }
}

all works if use branch feature/gen3_spi_transfer/ch50466
