Upgraded An Existing PixiJSv4 Game To PixiJSv5 - Now Have Bad Warning?

Hi,

We took an older PixiJSv4 game we made and upgraded it to PixiJSv5.
Game runs, but there is a bad warning in Internet browser's console & we don't know how to fix it.
Below is the details, hope someone can help us!

WARNING:
"PixiJS Deprecation Warning: PIXI.loader instance has moved to PIXI.Loader.shared
Deprecated since v5.0.0"

CODE:
var Container = PIXI.Container,
    autoDetectRenderer = PIXI.autoDetectRenderer,
    loader = PIXI.loader,
    resources = PIXI.loader.resources,
    TextureCache = PIXI.utils.TextureCache,
    Texture = PIXI.Texture,
    Sprite = PIXI.Sprite,
    Text = PIXI.Text,
    Graphics = PIXI.Graphics;

Thanks in advance!
