+## 1.0.0-1.0.pre
+
+* DEPRECATED: `FirebaseApp.configure` method is now deprecated in favor of the `Firebase.initializeApp` method.
+* DEPRECATED: `FirebaseApp.allApps` method is now deprecated in favor of the `Firebase.apps` property.
+  * Previously, `allApps` was async & `apps` is now synchronous.
+* DEPRECATED: `FirebaseApp.appNamed` method is now deprecated in favor of the `Firebase.app` method.
+* BREAKING: `FirebaseApp.options` getter is now synchronous.
+
+* `FirebaseOptions` has been reworked to better match web property names:
+  * DEPRECATED: `googleAppID` is now deprecated in favor of `appId`.
+  * DEPRECATED: `projectID` is now deprecated in favor of `projectId`.
+  * DEPRECATED: `bundleID` is now deprecated in favor of `bundleId`.
+  * DEPRECATED: `clientID` is now deprecated in favor of `androidClientId`.
+  * DEPRECATED: `trackingID` is now deprecated in favor of `trackingId`.
+  * DEPRECATED: `gcmSenderID` is now deprecated in favor of `messagingSenderId`.
+  * Added support for `authDomain`.
+  * Added support for `trackingId`.
+  * Required properties are now `apiKey`, `appId`, `messagingSenderId` & `projectId`.
+
+* Added support for deleting Firebase app instances via the `delete` method on `FirebaseApp`.
+* Added support for returning consistent error messages from `firebase-dart` plugin.
+  * Any FlutterFire related errors now throw a `FirebaseException`.
+* Added a `FirebaseException` class to handle all FlutterFire related errors.
+  * Matching the web sdk, the exception returns a formatted "[plugin/code] message" message when thrown.
+* Added support for `setAutomaticDataCollectionEnabled` & `isAutomaticDataCollectionEnabled` on a `FirebaseApp` instance.
+* Added support for `setAutomaticResourceManagementEnabled` on a `FirebaseApp` instance.
+
+* Android: Gradle build tools updated to 3.6.3 from 3.3.0.
+* Android: Removed Gradle ‘hacks’ and upgrade Flutter SDK requirement from `>=1.12.13+hotfix.4` to `>=1.12.13+hotfix.5` - based on PR https://github.com/flutter/plugins/pull/2651
+* Android: Switched to using Firebase BoM to manage SDK versions
+
 ## 0.4.5
 
 * Update lower bound of dart dependency to 2.0.0.

+  * Added support for `authDomain`.
+  * Added support for `trackingId`.
+  * Required properties are now `apiKey`, `appId`, `messagingSenderId` & `projectId`.
+
+* Added support for deleting Firebase app instances via the `delete` method on `FirebaseApp`.
+* Added support for returning consistent error messages from `firebase-dart` plugin.
+  * Any FlutterFire related errors now throw a `FirebaseException`.
+* Added a `FirebaseException` class to handle all FlutterFire related errors.
+  * Matching the web sdk, the exception returns a formatted "[plugin/code] message" message when thrown.
+* Added support for `setAutomaticDataCollectionEnabled` & `isAutomaticDataCollectionEnabled` on a `FirebaseApp` instance.
+* Added support for `setAutomaticResourceManagementEnabled` on a `FirebaseApp` instance.
+
 ## 1.0.5
 
 * Update lower bound of dart dependency to 2.0.0.

+## 1.0.0-1.0.pre
+
+* DEPRECATED: `FirebaseApp.configure` method is now deprecated in favor of the `Firebase.initializeApp` method.
+* DEPRECATED: `FirebaseApp.allApps` method is now deprecated in favor of the `Firebase.apps` property.
+  * Previously, `allApps` was asynchronous where it is now synchronous.
+* DEPRECATED: `FirebaseApp.appNamed` method is now deprecated in favor of the `Firebase.app` method.
+* BREAKING: `FirebaseApp.options` getter is now synchronous.
+
+* `FirebaseOptions` has been reworked to better match web property names:
+  * DEPRECATED: `googleAppID` is now deprecated in favor of `appId`.
+  * DEPRECATED: `projectID` is now deprecated in favor of `projectId`.
+  * DEPRECATED: `bundleID` is now deprecated in favor of `bundleId`.
+  * DEPRECATED: `clientID` is now deprecated in favor of `androidClientId`.
+  * DEPRECATED: `trackingID` is now deprecated in favor of `trackingId`.
+  * DEPRECATED: `gcmSenderID` is now deprecated in favor of `messagingSenderId`.
+  * Added support for `authDomain`.
+  * Added support for `trackingId`.
+  * Required properties are now `apiKey`, `appId`, `messagingSenderId` & `projectId`.
+
+* Added support for deleting Firebase app instances via the `delete` method on `FirebaseApp`.
+* Added support for returning consistent error messages from `firebase-dart` plugin.
+  * Any FlutterFire related errors now throw a `FirebaseException`.
+* Added a `FirebaseException` class to handle all FlutterFire related errors.
+  * Matching the web sdk, the exception returns a formatted "[plugin/code] message" message when thrown.
+
 ## 0.1.2
 
 * Update lower bound of dart dependency to 2.0.0.

 # firebase_core_web
 
-The web implementation of [`firebase_core`][1].
+The web implementation of `firebase_core`.
 
-## Usage
+To learn more about Firebase, please visit the [Firebase website](https://firebase.google.com)
 
-### Import the package
+## Getting Started
 
-This package is the endorsed implementation of `firebase_core` for the web platform since version `0.4.3`, so it gets automatically added to your dependencies by depending on `firebase_core: ^0.4.3`.
+To get started with FlutterFire, please [see the documentation](https://firebase.flutter.dev/docs/overview)
+available at [https://firebase.flutter.dev](https://firebase.flutter.dev/docs/overview)
 
-No modifications to your `pubspec.yaml` should be required in a recent enough version of Flutter (`>=1.12.13+hotfix.4`):
-
-```yaml
-...
-dependencies:
-  ...
-  firebase_core: ^0.4.3
-  ...
-```
-
-### Updating `index.html`
-
-Due to [this bug in dartdevc][2], you will need to manually add the Firebase JavaScript file to your `index.html` file.
-
-In your app directory, edit `web/index.html` to add the line:
-
-```html
-<html>
-    ...
-    <body>
-        <script src="https://www.gstatic.com/firebasejs/7.5.0/firebase-app.js"></script>
-        <!-- Other firebase SDKs/config here -->
-        <script src="main.dart.js"></script>
-    </body>
-</html>
-```
-
-### Initialize Firebase
-
-If your app is using the "default" Firebase app, you need to initialize it now, following the steps in the [Firebase Web Setup][3] docs.
-
-Specifically, you'll want to add the following lines to your `web/index.html` file:
-
-```html
-<body>
-  <!-- Previously loaded Firebase SDKs -->
-
-  <!-- ADD THIS BEFORE YOUR main.dart.js SCRIPT -->
-  <script>
-    // TODO: Replace the following with your app's Firebase project configuration.
-    // See: https://support.google.com/firebase/answer/7015592
-    var firebaseConfig = {
-      apiKey: "...",
-      authDomain: "[YOUR_PROJECT].firebaseapp.com",
-      databaseURL: "https://[YOUR_PROJECT].firebaseio.com",
-      projectId: "[YOUR_PROJECT]",
-      storageBucket: "[YOUR_PROJECT].appspot.com",
-      messagingSenderId: "...",
-      appId: "1:...:web:...",
-      measurementId: "G-..."
-    };
-    // Initialize Firebase
-    firebase.initializeApp(firebaseConfig);
-  </script>
-  <!-- END OF FIREBASE INIT CODE -->
-
-  <script src="main.dart.js"></script>
-</body> 
-```
-
-### Using the plugin
-
-Once you have modified your `web/index.html` file you should be able to use `package:firebase_core` as normal.
-
-[1]: ../firebase_core/firebase_core
-[2]: https://github.com/dart-lang/sdk/issues/33979
-[3]: https://firebase.google.com/docs/web/setup#add-sdks-initialize
+Once installed, Firebase needs to be configured for Web Installation.  Please [see the documentation](https://firebase.flutter.dev/docs/installation/web) on Web Installation
