MQTT module stopped working with latest update

Hi All, I've been using the MQTT module without any problems for at least a month. However, I started having problems yesterday, which I see was the day that a new MQTT module was posted on https://www.espruino.com/modules

mqtt.connect() gives this immediate error:

>mqtt.connect()
=undefined
Uncaught SyntaxError: Got ':' expected EOF
 at line 1 col 70
...;var f=c.charCodeAt(0)>>4;a:{var d=c.substr(1,5);var k=1,l=0...

Code is running on
ESP8266-12E flashed with espruino_1v95_esp8266_4mb_combined_4096.­bin ...

Test program, which has worked without a problem is listed below.

Is there an error in the MQTT module? Is there a change in using it?
Also, a related question: is there a way to access a previous version of a module?

Thanks,

Dan

Program:

var wifi = require("Wifi");

  var server = 'm14.cloudmqtt.com';
  var options = {
          keep_alive: 60,
          port: xxxx,
          clean_session: true,
          client_id: "xxxx",
          username: "xxxx",
          password: "xxxx",
          protocol_name: "MQTT",
          protocol_level: 0 };

  var mqtt = require("MQTT").create(server, options); // changes here
    mqtt.on('connected', function() {
    mqtt.subscribe("red");
      mqtt.subscribe("blue");
    console.log("connected");
  });

mqtt.on('disconnected', function() {
  console.log("MQTT disconnected... reconnecting.");
  setTimeout(function() {
    mqtt.connect();
  }, 1000);
});
  
   mqtt.on('publish', function (pub) {  // this place throw error
    console.log("topic: "+pub.topic);
    console.log("message: "+pub.message);
    if (pub.topic == "red") {
     if (pub.message == "on") {digitalWrite(16,0);}
     if (pub.message == "off") {digitalWrite(16,1);}
    }
      if (pub.topic == "blue") {
     if (pub.message == "on") {digitalWrite(2,0);}
     if (pub.message == "off") {digitalWrite(2,1);}
    }   
  });

function onInit() {
  console.log("In onInit");
  wifi.connect("xxxx", {password:"xxxx"}, function(err){
console.log("connected? err=", err, "info=", wifi.getIP());
});
wifi.stopAP(); 
mqtt.connect(); 
}
