+
+New `editor` method that can be overridden to control when the normalization should stop. Default behavior (unchanged) is to throw an error when it iterates over 42 times the dirty paths length.
+
+```ts
+shouldNormalize: ({
+  iteration,
+  dirtyPaths,
+  operation,
+}: {
+  iteration: number
+  dirtyPaths: Path[]
+  operation?: Operation
+}) => boolean
+```
+
+- `editor.onChange` signature change: `(options?: { operation?: Operation }) => void` where `operation` is triggering the function.
+- `editor.normalizeNode` signature change: `(entry: NodeEntry, options?: { operation?: Operation }) => void` where `operation` is triggering the function.
+- `EditorNormalizeOptions` new option `operation?: Operation` where `operation` is triggering the function.
