@ -17,6 +17,8 @@ OPENSEADRAGON CHANGELOG
* DEPRECATION: MouseTracker exitHandler deprecated for name change to leaveHandler for consistency with DOM event names
* Added missing Button event object properties (were listed in documentation but not implemented)
* Fixed bug in Button class where two MouseTracker event handlers used an invalid "this" causing issues in some browsers
* MouseTracker: IE 10 - MSPointerEnter/MSPointerLeave didn't exist then, simulated with MSPointerOver/MSPointerOut
* MouseTracker: Simulate mouseover/mouseout on IE < 9
