 # Changelog
 
+## 8.12.0
+
+### Deprecations
+
+- Manual TTID ([#2477](https://github.com/getsentry/sentry-dart/pull/2477))
+
+### Fixes
+
+- Missing replay gestures on Android ([#2515](https://github.com/getsentry/sentry-dart/pull/2515))
+- Replay mask sizing on scaling transform widget children ([#2520](https://github.com/getsentry/sentry-dart/pull/2520))
+- Masking semi-transparent widgets ([#2472](https://github.com/getsentry/sentry-dart/pull/2472))
+- Check `SentryTracer` type in TTFD tracker ([#2508](https://github.com/getsentry/sentry-dart/pull/2508))
+
+### Features
+
+- Replay: device orientation change support & improve video size fit on Android ([#2462](https://github.com/getsentry/sentry-dart/pull/2462))
+- Support custom `Sentry.runZoneGuarded` zone creation ([#2088](https://github.com/getsentry/sentry-dart/pull/2088))
+  - Sentry will not create a custom zone anymore if it is started within a custom one.
+  - This fixes Zone miss-match errors when trying to initialize WidgetsBinding before Sentry on Flutter Web
+  - `Sentry.runZonedGuarded` creates a zone and also captures exceptions & breadcrumbs automatically.
+
+  ```dart
+  Sentry.runZonedGuarded(() {
+    WidgetsBinding.ensureInitialized();
+
+    // Errors before init will not be handled by Sentry
+
+    SentryFlutter.init(
+      (options) {
+      ...
+      },
+      appRunner: () => runApp(MyApp()),
+    );
+  } (error, stackTrace) {
+    // Automatically sends errors to Sentry, no need to do any
+    // captureException calls on your part.
+    // On top of that, you can do your own custom stuff in this callback.
+  });
+  ```
+
+- Warning (in a debug build) if a potentially sensitive widget is not masked or unmasked explicitly ([#2375](https://github.com/getsentry/sentry-dart/pull/2375))
+- Replay: ensure visual update before capturing screenshots ([#2527](https://github.com/getsentry/sentry-dart/pull/2527))
+
