@ -7,6 +7,7 @@ OPENSEADRAGON CHANGELOG
* Added ControlAnchor options for default controls (#304)
* Enabled basic cross-domain tile loading without tainting canvas (works in Chrome and Firefox) (#308)
* Added a ControlAnchor.ABSOLUTE enumeration. Enables absolute positioning of control elements in the viewer (#310)
* Added a 'navigator-scroll' event to Navigator. Fired when mousewheel/pinch events occur in the navigator (#310)
* Added a navigatorMaintainSizeRatio option. If set to true, the navigator minimap resizes when the viewer element is resized (#310)
* Added 'ABSOLUTE' as a navigatorPosition option, along with corresponding navigatorTop, navigatorLeft options. Allows the navigator minimap to be placed anywhere in the viewer (#310)
* Enhanced the navigatorTop, navigatorLeft, navigatorHeight, and navigatorWidth options to allow a number for pixel units or a string for other element units (%, em, etc.) (#310)
