+** BREAKING CHANGE **
+
+`TagNode.create` method now by default pass `null` to content instead of empty array `[]`
+
+```js
+  // new behavior
+  TagNode.create('img').toString() // -> [img]
+  // old behavior
+  TagNode.create('img', {}, []).toString() // -> [img][/img]
+```
+
+Migrate all calls of `TagNode.create('test-tag')` to `TagNode.create('test-tag', {}, [])
