 ### Breaking Changes
 
+Copy and paste as well as create got completely reworked:
+
 * `Create#start`: third argument is context, if you want to specify `source` do `{ source: source }`
 * `CopyPaste`: `elements.copied`, `element.copy`, `elements.copy`, `element.paste`, `elements.paste` removed in favor of `copyPaste.canCopyElements`, `copyPaste.copyElement`, `copyPaste.elementsCopied`, `copyPaste.pasteElement`, `copyPaste.pasteElements`
+* To prevent additional behavior on create after paste you should check for the `createElementsBehavior=false` hint
 * `Modeling#pasteElements` removed in favor of `Modeling#createElements`
 * `MouseTracking` removed in favor of `Mouse`
