 ### Features
 
+- Emit `transaction.data` inside `contexts.trace.data` ([#2284](https://github.com/getsentry/sentry-dart/pull/2284))
+- Blocking app starts span if "appLaunchedInForeground" is false. (Android only) ([#2291](https://github.com/getsentry/sentry-dart/pull/2291))
+- Replay: user-configurable masking (redaction) for widget classes and specific widget instances. ([#2324](https://github.com/getsentry/sentry-dart/pull/2324))
+  Some examples of the configuration:
+
+  ```dart
+  await SentryFlutter.init(
+    (options) {
+      ...
+      options.experimental.replay.mask<IconButton>();
+      options.experimental.replay.unmask<Image>();
+      options.experimental.replay.maskCallback<Text>(
+          (Element element, Text widget) =>
+              (widget.data?.contains('secret') ?? false)
+                  ? SentryMaskingDecision.mask
+                  : SentryMaskingDecision.continueProcessing);
+    },
+    appRunner: () => runApp(MyApp()),
+  );
+  ```
+
+  Also, you can wrap any of your widgets with `SentryMask()` or `SentryUnmask()` widgets to mask/unmask them, respectively. For example:
+
+  ```dart
+   SentryUnmask(Text('Not secret at all'));
+  ```
+

+    MaterialPageRoute(
+      builder: (context) => SentryFeedbackWidget(associatedEventId: id),
+      fullscreenDialog: true,

+  );
