@ -7,6 +7,16 @@ OPENSEADRAGON CHANGELOG
* Documentation fix (#1814 @kenanchristian)
* Better cleanup on destruction, to avoid memory leaks (#1832 @JoFrMueller)
* Miscellaneous code cleanup (#1840 @msalsbery)
* Improved browser sniffing - detect EDGE and CHROMEEDGE browsers
* Improved DOM event model feature detection
* Added support for options parameter on addEvent()/removeEvent (to support passive option)
* Added OpenSeadragon.eventIsCanceled() function for defaultPrevented detection on DOM events
* MouseTracker: better PointerEvent model detection - removed use of deprecated window.navigator.pointerEnabled
* MouseTracker: added overHandler/outHandler options for handling corresponding pointerover/pointerout events
* MouseTracker: changed enterHandler/leaveHandler to use DOM pointerenter/pointerleave events instead of simulating using pointerover/pointerout
* 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
2.4.2:
@ -54,7 +64,7 @@ OPENSEADRAGON CHANGELOG
* You can now prevent canvas-click events on the navigator (#1416)
* The navigator can now be restricted to just horizontal or just vertical panning (#1416)
* Fixed DziTileSource so it doesn't load levels above maxLevel or below minLevel, if set (#1492)
2.3.1:
* Debug mode now uses different colors for different tiled images (customizable via debugGridColor) (#1271)
