-#### Strong Mode

-* Removed ad hoc `Future.then` inference in favor of using `FutureOr`.  Prior to
-  adding `FutureOr` to the language, the analyzer implented an ad hoc type
-  inference for `Future.then` (and overrides) treating it as if the onValue
-  callback was typed to return `FutureOr` for the purposes of inference.
-  This ad hoc inference has been removed now that `FutureOr` has been added.
-
-  Packages that implement `Future` must either type the `onValue` parameter to
-  `.then` as returning `FutureOr<T>`, or else must leave the type of the parameter
-  entirely to allow inference to fill in the type.
-
-* During static analysis, a function or setter declared using `=>` with return
-  type `void` now allows the returned expression to have any type.

     the Dart VM process current and peak resident set size.
   * Added `RawSynchronousSocket`, a basic synchronous socket implementation.
 
+* `dart:` web APIs have been updated to align with Chrome v50.
+   This change includes **a large number of changes**, many of which are
+   breaking. In some cases, new class names may conflict with names that exist
+   in existing code.
+
+* `dart:html`
+
+  * **REMOVED** classes: `Bluetooth`, `BluetoothDevice`,
+    `BluetoothGattCharacteristic`, `BluetoothGattRemoteServer`,
+    `BluetoothGattService`, `BluetoothUuid`, `CrossOriginConnectEvent`,
+    `DefaultSessionStartEvent`, `DomSettableTokenList`, `MediaKeyError`,
+    `PeriodicSyncEvent`, `PluginPlaceholderElement`, `ReadableStream`,
+    `StashedMessagePort`, `SyncRegistration`
+
+  * **REMOVED** members:
+    * `texImage2DCanvas` was removed from `RenderingContext`.
+    * `endClip` and `startClip` were removed from `Animation`.
+    * `after` and `before` were removed from `CharacterData`, `ChildNode` and
+      `Element`.
+    * `keyLocation` was removed from `KeyboardEvent`. Use `location` instead.
+    * `generateKeyRequest`, `keyAddedEvent`, `keyErrorEvent`, `keyMessageEvent`,
+      `mediaGroup`, `needKeyEvent`, `onKeyAdded`, `onKeyError`, `onKeyMessage`,
+      and `onNeedKey` were removed from `MediaElement`.
+    * `getStorageUpdates` was removed from `Navigator`
+    * `status` was removed from `PermissionStatus`
+    * `getAvailability` was removed from `PreElement`
+
+  * Other behavior changes:
+    * URLs returned in CSS or html are formatted with quoted string.
+      Like `url("http://google.com")` instead of `url(http://google.com)`.
+    * Event timestamp property type changed from `int` to `num`.
+    * Chrome introduced slight layout changes of UI objects.
+      In addition many height/width dimensions are returned in subpixel values
+      (`num` instead of whole numbers).
+    * `setRangeText` with a `selectionMode` value of 'invalid' is no longer
+      valid. Only "select", "start", "end", "preserve" are allowed.
+
+* `dart:svg`
+
+  * A large number of additions and removals. Review your use of `dart:svg`
+    carefully.
+
+* `dart:web_audio`
+
+  * new method on `AudioContext` – `createIirFilter` returns a new class
+    `IirFilterNode`.
+
+* `dart:web_gl`
+
+  * new classes: `CompressedTextureAstc`, `ExtColorBufferFloat`,
+    `ExtDisjointTimerQuery`, and `TimerQueryExt`.
+
+  * `ExtFragDepth` added: `readPixels2` and `texImage2D2`.

 ### Tool Changes
