Why doesn't work the PlayerVars with the YouTube API anymore?

Question

I posted the YouTube API and a video on my site a few days ago. I have set some PlayerVars. Everything worked then. Unfortunately, I noticed today that the player is not working properly anymore. All the PlayerVars are set in the iframe link, but they will not be executed (for example, 'showinfo': 0 will still display the video info). What can this be? Even if I remove all the changes I made since putting the video online, it will not work properly again.

HTML:

<div id="aboutVideoVideo"></div>

JavaScript:

var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
    player = new YT.Player('aboutVideoVideo', {
        height: '100%',
        width: '100%',
        videoId: 'xxx_xx',
        playerVars: {
            'showinfo': 0,
            'disablekb': 1,
            'fs': 0,
            'iv_load_policy': 3,
            'modestbranding': 1,
            'rel': 0
        },
        events: {
            'onReady': onPlayerReady
        }
    });
}
function onPlayerReady(event) {
    event.target.playVideo();
    event.target.pauseVideo();
    event.target.unMute();
}

iframe result:

<iframe id="aboutVideoVideo" frameborder="0" allowfullscreen="1" allow="autoplay; encrypted-media" title="YouTube video player" width="100%" height="100%" src="https://www.youtube.com/embed/xxx_xx?showinfo=0&amp;disablekb=1&amp;fs=0&amp;iv_load_policy=3&amp;modestbranding=1&amp;rel=0&amp;enablejsapi=1&amp;origin=http%3A%2F%2Fxxx.xxx.xxx.xxx&amp;widgetid=1"></iframe>

There has been a recent change in the Youtube embed API. Showinfo parameter has been depreciated. The video title, avatar, watch later and share icons will be displayed on loading, mouseover and when paused. So showinfo=0 doesn't work anymore.

There's also a change in the rel parameter.
