* There is now a 'full-screen' event with a `fullScreen` property (true if it has gone to full screen).
* There are now 'pre-full-page' and 'pre-full-screen' events that include a `preventDefaultAction` property you can set in your handler to cancel. They also have `fullPage` and `fullScreen` properties respectively, to indicate if they are going into or out of the mode.
* BREAKING CHANGE: Removed the 'onPageChange' callback from the viewer options. Viewer.goToPage() now raises the 'page' event only (#285)
* Major documentation improvements (#281)
* MouseTracker now passes the original event objects to its handler methods (#23)
* MouseTracker now supports an optional 'moveHandler' method for tracking mousemove events (#215)
* Added stopHandler to MouseTracker. (#262)
@ -56,7 +57,8 @@ OPENSEADRAGON CHANGELOG
* Viewer.innerTracker.scrollHandler: preventDefaultAction == true prevents viewer zooming on mousewheel/pinch
* Fixed: IE8 error with custom buttons - "Object doesn't support this action" (#279)
* Support IIIF servers that don't report tile dimensions (#286)
* Added an autoResize option. Default is true. When set to false, the viewer takes no action when its container element is resized.
* Added an autoResize option. Default is true. When set to false, the viewer takes no action when its container element is resized. (#291)
* Added a static 'version' property to OpenSeadragon. Useful for plugins that require specific OpenSeadragon versions. (#292)
