+## Migrating to v0.6.x
+
+starting in 0.6.x `change` event are no longer sent (for pretty much most nodes!) when an item is just added/deleted unless it also changes other nodes (was incorrect and causing inefficiencies). You may need to track `added|removed` [events](https://github.com/gridstack/gridstack.js/tree/develop/doc#events) if you didn't and relied on the old broken behavior.

 ## Migrating to v1.0.0
 
 v1.0.0 removed Jquery from the API and external dependencies, which will require some code changes. Here is a list of the changes:
 
-1. your code only needs to include `gridstack.all.js` and `gristack.css` (don't include other) and is recommended you do that as internal dependencies will change. Right now jquery+jquery-ui (trimmed versions) are still being used internally for a short while.

-We're working on implementing support for other drag'n'drop libraries through the plugin system. Right now it is still jquery-ui based (but minimal build content)
+**NOTE: jQuery Applications** 
+
+We're working on implementing HTML5 drag'n'drop through the plugin system. Right now it is still jquery-ui based. Because of that we are still bundling `jquery` (3.4.1) + `jquery-ui` (1.12.1 minimal drag|drop|resize) internally in `gridstack.all.js`. IFF your app needs to bring it's own version instead, you should **instead** include `gridstack-poly.min.js` (optional IE support) + `gridstack.min.js` + `gridstack.jQueryUI.min.js` + after you import your libs.
