|
||||
2.0.0: (in progress)
|
||||
|
||||
* True multi-image mode (#450)
|
||||
* BREAKING CHANGE: Passing an array for the tileSources option is no longer enough to trigger sequence mode; you have to set the sequenceMode option to true as well
|
||||
* BREAKING CHANGE: Navigator no longer sends an open event when its viewer opens
|
||||
* BREAKING CHANGE: Viewer.drawers and Viewer.drawersContainer no longer exist
|
||||
* BREAKING CHANGE: A Viewer's Drawer and Viewport are now made once per Viewer and reused for every image that Viewer opens (rather than being recreated for every open); this means if you change Viewer options between opens, the behavior is different now.
|
||||
@ -35,6 +36,7 @@ OPENSEADRAGON CHANGELOG
|
||||
* New Viewport method for managing homeBounds as well as constraints: setHomeBounds
|
||||
* Viewport.open supports positioning config properties
|
||||
* Margins option to push the home region in from the edges of the Viewer (#505)
|
||||
* Rect and Point toString() functions are now consistent: rounding values to nearest hundredth
