 We now have a native HTML5 drag'n'drop through the plugin system (default), but the jquery-ui version can be used instead. It will bundle `jquery` (3.5.1) + `jquery-ui` (1.12.1 minimal drag|drop|resize) + `jquery-ui-touch-punch` (1.0.8 for mobile support) in `gridstack-jq.js`. 
 
-**NOTE: in v1.x** IFF you want to use gridstack-jq instead and your app needs to bring your own JQ version, you should **instead** include `gridstack-poly.min.js` (optional IE support) + `gridstack.min.js` + `gridstack.jQueryUI.min.js` after you import your JQ libs. But note that there are issue with jQuery and ES6 import (see [1306](https://github.com/gridstack/gridstack.js/issues/1306)).
+**NOTE: in v4, v3**: we ES6 module import jquery & jquery-ui by name, so you need to specify location of those .js files, which means you might be able to bring your own version as well. See the include instructions.

 As for events, you can still use `$(".grid-stack").on(...)` for the version that uses jquery-ui for things we don't support.
