+### BREAKING CHANGES
+
+- Minimum Flutter version required is `1.22.0` and Dart SDK `>=2.12.0-0 <3.0.0`
+- Removed `debuggingEnabled` WebView option; on Android you should use now the `AndroidInAppWebViewController.setWebContentsDebuggingEnabled(bool debuggingEnabled)` static method; on iOS, debugging is always enabled
+- `allowUniversalAccessFromFileURLs` and `allowFileAccessFromFileURLs` WebView options moved from Android-specific options to cross-platform options.
