+### 4. Removal of the magnifier feature
+
+Unfortunately, **due to the high volume of issues and bugs introduced by the magnifier**, this feature has been removed to ensure stability.
+
+This feature was introduced in [9.6.0](https://pub.dev/packages/flutter_quill/versions/9.6.0/changelog#960) which supports Android and iOS only.
+
+For more details, refer to [#2406](https://github.com/singerdmx/flutter-quill/issues/2406).
