+Release of Sentry's new SDK for Dart/Flutter.
+
+New features not offered by <= v4.0.0:
+
+## Dart SDK
+
+* Sentry's [Unified API](https://develop.sentry.dev/sdk/unified-api/).
+* Complete Sentry's [Protocol](https://develop.sentry.dev/sdk/event-payloads/) available.
+* [Dart SDK](https://docs.sentry.io/platforms/dart/) docs.
+* Automatic [HTTP Breadcrumbs](https://docs.sentry.io/platforms/dart/usage/advanced-usage/#automatic-breadcrumbs) for [http.Client](https://pub.dev/documentation/http/latest/http/Client-class.html)
+* No boilerplate for `runZonedGuarded` and `Isolate.current.addErrorListener`
+* All events are enriched with [Scope's Contexts](https://develop.sentry.dev/sdk/event-payloads/#scope-interfaces), this includes Breadcrumbs, tags, User, etc...
+
+## Flutter SDK
+
+* The Flutter SDK is built on top of the Dart SDK, so it includes all the available features, plus
+* [Flutter SDK](https://docs.sentry.io/platforms/flutter/) docs.
+* Automatic [NavigatorObserver Breadcrumbs](https://docs.sentry.io/platforms/flutter/usage/advanced-usage/#automatic-breadcrumbs)
+* Automatic [Device's Breadcrumbs](https://docs.sentry.io/platforms/flutter/usage/advanced-usage/#automatic-breadcrumbs) through the Android and iOS SDKs or via Sentry's `WidgetsBindingObserver` wrapper
+* No boilerplate for `FlutterError.onError`
+* All events are enriched with [Contexts's data](https://develop.sentry.dev/sdk/event-payloads/contexts/), this includes Device's, OS, App info, etc...
+* Offline caching
+* [Release health](https://docs.sentry.io/product/releases/health/)
+* Captures not only Dart and Flutter errors, but also errors caused on the native platforms, Like Kotlin, Java, C and C++ for Android and Swift, ObjC, C, C++ for iOS
+* Supports Fatal crashes, Event is going to be sent on App's restart
+* Supports `split-debug-info` for Android only
+* Flutter Android, iOS and limited support for Flutter Web
+
+Improvements:
 
 * Feat: Added a copyWith method to all the protocol classes
 
+Packages were released on [sentry pubdev](https://pub.dev/packages/sentry) and [sentry_flutter pubdev](https://pub.dev/packages/sentry_flutter)
+
+## Sentry Self Hosted Compatibility
+
+* Since version `4.0.0` of the `sentry_flutter`, [Sentry's version >= v20.6.0](https://github.com/getsentry/onpremise/releases) is required. This only applies to on-premise Sentry, if you are using sentry.io no action is needed.
+
+We'd love to get feedback.

 Versions below `3.0.1` are deprecated.
 
-###### Preleases (v4.0.0)
-
-- If you wish to try out our Prelease versions, check out the inner [dart](https://github.com/getsentry/sentry-dart/tree/main/dart) and [flutter](https://github.com/getsentry/sentry-dart/tree/main/flutter) folders. 
-
 ##### Usage
 
-Sign up for a Sentry.io account and get a DSN at http://sentry.io.
-
-Add `sentry` dependency to your `pubspec.yaml`:
-
-```yaml
-dependencies:
-  sentry: ">=3.0.1 <4.0.0"
-```
-
-In your Dart code, import `package:sentry/sentry.dart` and create a `SentryClient` using the DSN issued by Sentry.io:
-
-```dart
-import 'package:sentry/sentry.dart';
-
-final SentryClient sentry = new SentryClient(dsn: YOUR_DSN);
-```
-
-In an exception handler, call `captureException()`:
-
-```dart
-main() async {
-  try {
-    doSomethingThatMightThrowAnError();
-  } catch(error, stackTrace) {
-    await sentry.captureException(
-      exception: error,
-      stackTrace: stackTrace,
-    );
-  }
-}
-```
-
-##### Tips for catching errors
-
-- Use a `try/catch` block, like in the example above.
-- Create a `Zone` with an error handler, e.g. using `runZonedGuarded`.
-
-  ```dart
-  var sentry = SentryClient(dsn: "https://...");
-  // Run the whole app in a zone to capture all uncaught errors.
-  runZonedGuarded(
-    () => runApp(MyApp()),
-    (error, stackTrace) async {
-      try {
-        sentry.captureException(
-          exception: error,
-          stackTrace: stackTrace,
-        );
-        print('Error sent to sentry.io: $error');
-      } catch (e) {
-        print('Sending report to sentry.io failed: $e');
-        print('Original error: $error');
-      }
-    },
-  );
-  ```
-- For Flutter-specific errors (such as layout failures), use `FlutterError.onError`. For example:
-
-  ```dart
-  var sentry = SentryClient(dsn: "https://...");
-  FlutterError.onError = (details, {bool forceReport = false}) {
-    try {
-      sentry.captureException(
-        exception: details.exception,
-        stackTrace: details.stack,
-      );
-    } catch (e) {
-      print('Sending report to sentry.io failed: $e');
-    } finally {
-      // Also use Flutter's pretty error logging to the device's console.
-      FlutterError.dumpErrorToConsole(details, forceReport: forceReport);
-    }
-  };
-  ```
-- Use `Isolate.current.addErrorListener` to capture uncaught errors
-  in the root zone.
