    * Removed `CesiumViewerWidget` and replaced it with a new `Viewer` widget with mixin architecture. This new widget does not depend on Dojo and is part of the combined Cesium.js file. It is intended to be a flexible base widget for easily building robust applications.  See [#838](https://github.com/AnalyticalGraphicsInc/cesium/pull/838) for the full details.
    * Removed the Dojo-based `checkForChromeFrame` function, and replaced it with a new standalone version that returns a promise to signal when the asynchronous check has completed. 
 * Fix resizing issues in `CesiumWidget` ([#608](https://github.com/AnalyticalGraphicsInc/cesium/issues/608), [#834](https://github.com/AnalyticalGraphicsInc/cesium/issues/834)).
