I only would like to inform you that you forgot to set originX and originY to center. I copied the latest version and noticed that all my objects are moved. I set the origin to center and then everything looks like before. In the doc default value is also center.

You can still keep things the same in your app by simply doing something like
fabric.Object.prototype.originX = fabric.Object.prototype.originY = 'center'
