 * V11 add new `GridStack.renderCB` that is called for you to create the widget content (entire GridStackWidget is passed so you can use id or some other field as logic) while GS creates the 2 needed parent divs + classes, unlike `GridStack.addRemoveCB` which doesn't create anything for you. Both can be handy for Angular/React/Vue frameworks.
-* `addWidget(w: GridStackWidget)` is now the only supported format, no more string content passing. You will need to create content yourself (`Util.createWidgetDivs()` can be used to create parent divs) then call `makeWidget(el)` instead.
